KRATOS 9e800b4ffc fix five concurrency/leak bugs (swarm, specialist, oauth, mcp, cron) (#265)
Surfaced by a full-tree audit; each ships a regression test where the
behavior is deterministically testable.

- swarm: deliver a handoff's mailbox note BEFORE registering the new task,
  so a mailbox failure can't leave a phantom pending task in the coordinator.
- specialist: put a foreground sub-agent child in its own process group and
  group-kill on cancel/timeout (+ WaitDelay backstop), so a build/server it
  forked dies with it instead of orphaning.
- oauth: serialize on-demand token refresh per key (keyed mutex) and re-load
  inside the lock, so parallel callers don't each spend the single-use
  refresh token (all but one would otherwise fail at the token endpoint).
- mcp: treat a "source already gone" rename during legacy-token migration as
  success, so a concurrent migrator doesn't wrongly drop an OAuth MCP server.
- cron: claim a due job atomically (advance NextRunAt under the per-job lock)
  before running it, so two schedulers can't double-fire the same job.

KRATOS 7691ff18f9 fix model-discovery fallback + redact opaque Authorization tokens (#266)
Two robustness/security bugs from a full-tree audit, each with a test.

- providermodeldiscovery: when a live /models probe succeeds (200) but its
  model ids don't match the curated catalog, the merge was empty and the whole
  live+curated list was discarded — the picker collapsed to the bare built-in
  set with a misleading "no model ids" error. Now fall back to the curated
  catalog instead of returning an empty list.
- redaction: Authorization / Proxy-Authorization headers carrying an opaque
  token or a custom (non-standard) scheme were not redacted in free text (logs,
  command/diff output, errors, session search), echoing live credentials back
  into model context and rendered output. The scheme is now optional, so any
  credential value is redacted to end-of-line; a recognized scheme name is
  still kept for readability.

KRATOS b0a280eaf6 audit: fix four high-severity concurrency/correctness bugs (#261)
Surfaced by a full-tree audit; all are latent (the suite passed) and live
in race windows / error edges the tests don't exercise. Each ships a
regression test.

- swarm: liveAgents() now counts queued specs, so AdoptOrphans can no longer
  re-dispatch (double-execute) a task whose member is merely waiting for a
  free slot over the concurrency cap.
- cron/hooks/oauth: stale-lock reclaim is now atomic (rename aside, then
  verify-and-restore if it turns out fresh) instead of a blind Remove that
  let two racers both reclaim and hold the lock; also falls through to the
  bounded wait instead of hot-spinning when a reclaim never wins.
- lsp: a dead language-server session is evicted and restarted instead of
  being returned forever, so one server crash no longer permanently breaks
  diagnostics (and spuriously fails self-correct every iteration).
- config: an API-key env var no longer overwrites a same-named
  compatible-transport provider's kind when no base URL is supplied.

KRATOS 1c30f4c117 audit fixes: cron lock, accounting race, O(n²) hot paths, /style wiring (#260)
* audit fixes: cron lock, accounting race, O(n^2) hot paths, /style wiring

Fixes five verified findings from a code audit. Two related findings were already
addressed upstream and three need larger/separate work (noted below).

H-1 cron store: cross-process lock for the read-modify-write.
Two schedulers seeing a job due raced the metadata read-modify-write; fireJob
even documented it ("full atomicity needs file locking"). Adds a per-job O_EXCL
lock (mirroring internal/oauth's pattern, stale-reclaim included) and a Mutate
primitive doing the re-read+modify+write atomically. Update/Remove lock too. The
lock is held only for the millisecond RMW, never across a job's exec.

M-5 specialist accounting: close the check-then-append race.
specialistEventExists (unlocked ReadEvents) + a later AppendEvent let two
finishers (TaskOutput poll vs onExit, even cross-process) both pass the check and
write duplicate stop/usage events. Adds sessions.Store.AppendEventUnlessExists
(check + append atomic under the session lock) and routes the stop and usage
paths through it.

M-2 hooks audit: O(1) sequence via tail read.
append re-read and scanned the whole audit log every call to find the max
sequence (O(n^2) over a session). Reads only the file tail now; multi-process
safe (the log is a shared global file), unlike an in-memory counter which would
collide sequences across processes.

M-4 transcript rehydration: O(n^2) -> O(n).
The three resume/rewind/compact rehydration loops called appendTranscriptRow per
event, each re-scanning every existing row for the keyed-row dedup. A bulk
appendTranscriptRowsDedup builds the key set once; semantics are identical.

M-6 /style: actually shape responses.
The TUI /style command stored a style but never threaded it anywhere. Adds
agent.Options.ResponseStyle, a system-prompt directive for concise/explanatory/
review, and wires m.responseStyle through the run. "balanced" is a no-op (prompt
byte-identical to before).

Already addressed upstream (no change):
- M-1 forked-session double-count: Store.Fork already skips EventUsage events,
  with a comment naming the exact double-count it prevents.
- M-3 lineage O(N^2): Tree already does a single store.List() scan and indexes
  children in memory; no path calls List per node.

Deferred (need larger/separate changes):
- M-7 escalate_model in the TUI needs a ModelSwitcher that builds a provider
  mid-run; registering the tool alone yields a tool that errors on call.
- L-1 MCP SSE reconnect is a stream-lifecycle change (low-likelihood after the
  8 MiB per-event cap).
- L-2 dead-code removal belongs in a dedicated cleanup sweep.

Tests: per-fix unit tests including concurrency (cron Mutate, sessions
AppendEventUnlessExists) under -race; full go test ./... green.

* fix(windows): treat ERROR_ACCESS_DENIED as lock contention (cron + oauth)

The Windows smoke run failed TestMutateIsAtomicUnderConcurrency with
"...lock: Access is denied" (FireCount 19/20). On Windows a concurrent holder's
os.Remove leaves the lock file in a delete-pending state, so an O_EXCL create
races it with ERROR_ACCESS_DENIED (os.ErrPermission) rather than ErrExist — the
retry loop only treated ErrExist as contention and hard-failed.

Treat os.ErrPermission as contention (retry) in the new cron lock and in the
oauth lock it mirrors (oauth's own concurrent test exposed the same pre-existing
bug under the added load). Unix is unaffected — it returns ErrExist.

* fix: address review — cross-process atomic audit append + AppendRun guard

Addresses the review feedback on this PR.

P1 (blocking): AuditStore.append is now cross-process atomic.
The O(1) tail read observes another process's prior appends, but the read-then-
append was not atomic across processes — two could both read sequence N and write
N+1. Wraps lastSequence()+append in a per-file O_EXCL lock (hooks/lock.go, same
stale-reclaim + Windows ErrPermission handling as cron/oauth); store.mu stays as
the in-process fast path. Adds TestAuditStoreSequenceConcurrent (4 stores x 12
goroutines on one file -> unique dense sequences), which the prior sequential
test could not catch. Walked back the comment that oversold the tail read.

P2: AppendRun no longer resurrects a removed job.
fireJob's AppendRun ran after Mutate released the per-job lock; a Remove in that
window let AppendRun's MkdirAll recreate the dir with an orphaned runs.jsonl.
AppendRun now takes the per-job lock and bails if metadata.json is gone. Adds
TestAppendRunDoesNotResurrectRemovedJob.

P2: lastSequence ReadAt tolerates a short final read.
ReadAt may return io.EOF with n < len(buf) if the file shrank between Stat and
the read; treat EOF as non-fatal and use buf[:n] (matches lastEventSequence).

P3: oauth stale-reclaim no-op removed.
The double os.ReadFile "stale == data" guard compared the file to itself read
twice in a row (always true); staleness is decided by the mtime check, so the
guard is dropped (behavior-preserving).

Tests under -race; cron/hooks/oauth green. A shared filelock helper would DRY the
three near-identical locks — left as a follow-up to avoid churning the
already-green cron/oauth packages here.

Vasanth T b237e9849a feat(tui): sticky plan panel + specialist task cards + task table overlay (#255)
* feat(tui): sticky plan panel + specialist task cards + task table overlay

Three new TUI surfaces that give users live visibility into agent progress
and specialist delegation, so long turns and subagent work never look frozen.

Sticky plan panel (plan_panel.go):
- Pinned between the title bar and transcript body, shows the agent's
  step-by-step plan from the update_plan tool as a live checklist.
- Header with spinner + progress count + elapsed; text progress bar;
  per-step list with status icons (✓ completed, ⠹ in_progress, ○ pending,
  ✗ failed) and individual step timings.
- Auto-collapses to a one-line green summary 30s after completion.
  Ctrl+P toggles expand/collapse.
- Plan state synced from update_plan tool results via CurrentPlan();
  timestamps preserved across the tool's full-replacement updates by
  matching on content.

Specialist cards (specialist_card.go):
- New rowSpecialist transcript row kind; EventSpecialistStart/Stop
  now handled in session.go hydration (previously fell through to
  default and were silently dropped on resume).
- Animated card with spinner + name + task + elapsed + token count +
  tool call count. Blue while running, green when done, red on error.
- specialistTracker tracks live state; Task tool calls/returns are
  intercepted in the OnToolCall/OnToolResult callbacks to start/complete
  tracking and emit card rows.
- Height cache marks running specialist rows unstable so the spinner
  animates.

Task table overlay (task_table.go):
- Ctrl+G toggles a full-width overlay showing all specialists in the
  session as a sortable table: #, Specialist, Task, Status, Time,
  Tokens, Tools.
- Summary bar with running/completed/error counts, total tokens,
  aggregate elapsed.
- Arrow keys navigate rows; Esc closes the overlay.

Tests: plan_panel_test.go (7 tests), specialist_card_test.go (11 tests),
task_table_test.go (8 tests). All existing TUI tests pass.

* fix(update_plan): expose structured nested item schema so models stop sending bad arguments

The plan property's Items schema was omitted because of an outdated comment
claiming the serializer drops nested Properties/Required. The serializer
(propertyToRuntimeMap) already handles them recursively. Without the nested
schema, weaker models guessed the item structure from a text description and
sent malformed arguments, hitting the 4-strike guardrail halt.

Now exposes Items as an object with content (string, required), status (enum),
and notes (string).

* fix(tui): route plan + specialist updates through message sink, not stale closures

The OnToolCall/OnToolResult callbacks captured model by value, so
m.plan.updateFromItems() and m.specialists.start/complete() mutated stale
copies that never reached the live model. Introduced planUpdateMsg,
specialistStartMsg, and specialistCompleteMsg tea.Msg types sent through
runtimeMessageSink, handled in updateModel() where they mutate the live model.

* feat(tui): subchat drill-in for specialist sessions

Enter on a task table row loads the child session's events and swaps the
transcript view to show the subagent's full conversation (user messages,
agent text, tool calls, results). A nav bar at the top shows the specialist
name/task and a back hint. ArrowUp or Esc pops back to the main chat at the
saved scroll position.

- subchat.go: subchatState with enter/exit, renderSubchatNavBar
- transcript_selection.go: transcriptBodyItemsFromRows renders arbitrary
  rows (reuses the same rendering pipeline as the main transcript)
- model.go: Enter on task table row triggers drill-in; ArrowUp/Esc exits;
  transcriptView() short-circuits to child rows when subchat is active

* fix(ci): strip CRLF line endings and BOM from plan_tool_test.go and update_plan.go

gofmt and git diff --check failed on ubuntu CI because PowerShell's
Set-Content wrote UTF-8 with BOM and CRLF. Stripped both to plain LF
without BOM.

* feat(tui): add renderLeftRuleCard helper for borderless specialist cards

* feat(tui): switch specialist cards to left-rule rendering, drop hint line

* feat(tui): add renderSpecialistSummary one-line rollup for specialist cards

* fix(tui): correct slice offset in renderSpecialistSummary and add pluralization test

The muted tail was sliced at summary[len(spinnerView)] but the spinner
sits at byte offset 2 (after the 2-space indent), so the slice cut into
the spinner's UTF-8 continuation bytes and dropped the indent. Slice at
2+len(spinnerView) instead. Also add a test asserting '2 errors' is
present and '2 error' (singular) is absent when two specialists errored.

* refactor(tui): remove task table overlay — cards carry everything now

* feat(tui): render specialist summary line above cards in transcript

* feat(tui): mark specialist card lines as clickable selectable rows

* feat(tui): click specialist card to drill into subchat, Enter as keyboard fallback

* tui: clear selectedSpecialistID after Enter drill-in

Fixes Task 7 review issue: selectedSpecialistID persisted after
Enter drill-in, causing a subsequent Enter to re-drill into the
specialist's subchat instead of submitting the composer. Clear it
immediately after subchat.enter succeeds so the keyboard fallback
is one-shot per click; click re-sets it, so click->Enter still works.

* chore: gofmt model.go + test files

* chore: gitignore .superpowers/ and docs/superpowers/ — local skill artifacts

* fix(tui): remove Enter keyboard fallback for subchat drill-in — mouse click only

* fix(tui): reconcile specialist childSessionID from tool call ID to real session ID on completion

* feat(specialist): add Progress callback field to RunOptions and TaskRunOptions

* feat(specialist): stream child stdout line-by-line via Progress callback

* feat(agent): wire OnToolProgress callback for specialist child events

* feat(tui): show live tool-call progress in specialist cards

* fix(swarm): update RunChild mock signature for new progress callback param

* fix(tui): render plan panel inline in transcript, not pinned at top

* chore: gofmt model.go, specialist_card.go, specialist_click_test.go

* fix(tui): address PR review - plan panel without specialists, stream reader safety, resume dedup + payload keys

KRATOS b64a9d3de9 tools: tool_search redirects eager-tool lookups instead of "no tools matched" (#259)
When the model calls tool_search for a tool it already has eagerly (e.g.
select:Task or select:update_plan), resolveExact/noMatchMessage only ever
consulted the DEFERRED set, so it fell through to a misleading
"No tools matched. Available: <deferred tools>". That implies the tool does not
exist, and weaker models (e.g. cloud deepseek/minimax) loop retrying tool_search
instead of just calling the tool.

tool_search now recognizes eager tools (registered, not deferred, passing the
operator filters) and, for a select: or keyword query that names one:
- with no deferred match: redirect — "<tool> is already in your tool list — call
  it directly" instead of "no tools matched";
- mixed with a deferred match: load the deferred tool AND append the note;
- a genuinely-unknown name still gets the honest "no tools matched".

Surgical: only the error/redirect path changed; loading deferred tools is
unchanged. NewToolSearchTool already holds the full registry — it just wasn't
using it to recognize eager tools.

Tests: eager redirect via select: and keyword, mixed load+note, and
unknown-stays-honest; all existing tool_search tests pass.

KRATOS eed61cf8ec tools: defer swarm tool schemas + keyless SearXNG web_search backend (#258)
Two fixes for the raised issues — the idle tool-schema prefix and native web search.

Idle prefix — make the swarm tools deferred-eligible:
- The 7 swarm_* tools are an advanced, rarely-first-move feature the base system
  prompt does not name, so they now implement Deferred() and load on demand via
  tool_search instead of shipping full schemas in the eager per-request prefix.
  Core tools and specialist Task stay eager (no friction on common operations).
- partitionTools keys off the shared tools.IsDeferred check exactly as it does for
  MCP tools, so this reuses the existing, proven mechanism. Measured ~470 fewer
  prompt tokens per request in a swarm-enabled (--auto high) config, with no
  behavioral loss — swarm still works, just loaded when needed.

Web search — keyless SearXNG backend:
- web_search gains a "searxng" provider: ZERO_WEBSEARCH_PROVIDER=searxng with a
  SearXNG URL queries GET /search?format=json with NO API key, parsing the
  {results:[{title,url,content,score}]} shape. Self-host or point at any SearXNG
  instance for native search without baking a shared key or a flaky default.

Tests: swarm tools are deferred-eligible; the SearXNG backend issues the GET, sends
no auth header, maps fields, and respects the limit.

Anandan ac6addaa83 Align sandbox permission blocks and backend states (#253)
* Prompt for shell network permissions

Route network-risk shell calls through the existing permission prompt instead of hard-denying them at sandbox preflight. Approved network prompts apply the current turn/session request-permissions overlay so the effective sandbox policy is widened only after user approval.

Move network command detection into the shell AST analyzer for package installers, gh/git network subcommands, and python http.server so quoted process patterns such as pkill -f "python3 -m http.server 8000" are not misclassified as network activity.

* Auto-allow native-sandboxed shell commands

Remove the old hidden bash auto-allow environment/config path. Ordinary shell commands now use the active native sandbox as the permission boundary by default, while network, destructive, and workspace policy checks still run first.

Policy-only and disabled sandbox backends continue to require approval for shell commands, so unsandboxed execution is not silently allowed.

Convert recoverable outside-workspace file path violations into permission prompts instead of hard-denying in ask/auto modes.

Approved prompts now grant the requested filesystem scope through the existing request_permissions overlay for the current turn or session, so the follow-up sandbox evaluation and scoped file tools use the same policy path.

Shell network policy now serializes and evaluates only deny or allow. Request-permissions network grants widen to allow without domain lists, and platform profiles consume the binary mode directly.

The Linux helper no longer accepts proxy-route flags, Windows network hashes only the binary mode, and web tool tests assert they remain separate from shell network policy.

KRATOS 03784268ac token efficiency: lossless cost accounting + minified file reads (read_minified_file) (#256)
* token efficiency: lossless cost accounting + minified file reads

Two complementary improvements to how Zero handles tokens.

ACCOUNTING — make cost measurement lossless and correct:
- Carry all five token dimensions end-to-end (input, cache-read, cache-write,
  output, reasoning) in one Usage; add CacheWriteTokens (cache creation), which
  the Anthropic adapter previously parsed then discarded.
- Price cache-writes at their premium rate (Anthropic 1.25x input, derived per
  model). Regression-safe: a model without the rate bills cache-write at the
  input rate exactly as before.
- Persist cache-read/cache-write/reasoning in EventUsage so `zero usage report`
  reconstructs the SAME cost as the live tracker instead of over-pricing
  cache-heavy sessions. A single EventUsagePayload writer is paired with the
  reader so the JSON keys can't drift.
- Add a live context-window gauge to the status bar (used/window + percent,
  graded green/amber/red) using the last request's input tokens.

REDUCTION — read_minified_file, a dense token-cheap file view:
- New internal/minify package + read_minified_file tool returning a comment-free,
  line-number-free view: Go via the real go/parser AST; C/Java/CSS/SCSS/LESS/
  Python via a string-aware comment lexer (handles strings, char literals,
  triple-quotes, Java text blocks, Python f-strings incl. 3.12 same-quote
  nesting). Every other language falls back to whitespace-only, so the stripper
  can never corrupt content.
- ~32% fewer tokens on a realistic multi-file read; +~102 fixed tokens for the
  tool schema, recovered many times over by a single subsystem read.

Tests: cache-write pricing + fallback, lossless persistence round-trip, the
context gauge, comment-stripping golden cases per language (comment-chars in
strings, Java text blocks, Python f-string nesting, CSS has no //), and the
unsupported-language safe fallback. gofmt / vet / build / -race all green.

* specialist: register read_minified_file in the tool registry + read-only sets

Smoke caught TestKnownToolNamesMatchCoreRegistry drifting once read_minified_file
joined the core read-only tools: the specialist tool allowlist (knownToolNames),
the read-only/edit/execute categories, and the read-only auto-approve set did not
list it. It is a read-only companion to read_file, so it belongs alongside

KRATOS d739181951 tui: live working status (elapsed) + streaming reasoning preview so long turns never look frozen (#254)
* tui: live working status + streaming reasoning preview so long turns never look frozen

A long model stream or reasoning phase made the TUI look stuck: once partial text
streamed only a static cursor showed; during a think, just a static "Thinking"
header; and there was no elapsed time anywhere. On slow turns the user couldn't
tell whether the agent was working or hung.

- Always-on working status line: animated spinner + rotating verb + live elapsed
  ("8s", "1m04s"), rendered on every pending frame — including once partial text
  has streamed. The spinner tick is time-based (~80ms), so the elapsed clock keeps
  advancing even when the upstream goes silent mid-stream. Provider-agnostic.

- Live reasoning preview: during a think (before any answer text) the last 1-2
  lines of the streaming reasoning are shown dimmed beneath the working line,
  tail-truncated so a single growing reasoning line still visibly moves as tokens
  arrive. Skipped when the reasoning block is expanded (the full body shows).

Tests: formatWorkingElapsed, previewTail, interim block shows the working line with
streamed text, shows the reasoning preview while thinking, no duplicate preview when
expanded; updated the one reasoning-elapsed clock test for the extra turn-start stamp.

* tui: centralize run-start state in beginRun so spec-mode runs get the elapsed clock

Review follow-up (#254): the /spec draft and implementation launch paths set
pending and started the spinner but never set turnStartedAt, so the new working
status line showed the spinner/verb but no live elapsed time on spec runs (and
the draft path also skipped the working-verb reset the others did).

Extract beginRun(cancel) — runID++, activeRunID, runCancel, pending, turnStartedAt,
and the working-verb reset — and call it from all three launch paths (normal
prompt + spec draft + spec impl) so run-start state can no longer drift.

Test: TestSpecLaunchesSeedElapsedClock asserts both spec launches seed turnStartedAt.

Vasanth T ab3d09d78e feat(oauth): Hugging Face + ChatGPT Codex as first-class built-in OAuth presets (#245)
* feat(oauth): add Hugging Face + ChatGPT Codex as first-class built-in OAuth providers

Adds two new built-in OAuth presets that round out the existing OpenRouter and
xAI surfaces, so the TUI `/provider` OAuth chooser and `zero auth login` work
out of the box for these providers.

Hugging Face
- Preset scopes, endpoints, and OIDC issuer are pre-filled; the operator
  supplies a "public" OAuth client_id (no secret) via
  `ZERO_OAUTH_HUGGINGFACE_CLIENT_ID` after registering an app at
  huggingface.co/settings/applications/new.
- Default flow is RFC 8628 device code, so headless/SSH is the first-class
  path (matches the existing xAI posture).
- The bearer works against the OpenAI-compatible Inference Providers router
  at `https://router.huggingface.co/v1` for hundreds of OSS models.

ChatGPT (Codex backend)
- Uses the publicly-shipped Codex CLI client identity
  (`app_EMoamEEZ73f0CkXaXp7hrann`), opt-in via `ZERO_OAUTH_ALLOW_PRESETS=1`,
  overridable via `ZERO_OAUTH_CHATGPT_*`.
- The bespoke `provideroauth.ChatGPTLogin` extracts the `chatgpt_account_id`
  claim from the OIDC ID token (added as `IDToken` on the `oauth.Token`
  struct) and stores it on `Token.Account` so the Codex provider can inject
  it as a header on every request.
- A new `internal/providers/openai/codex.go` wraps the openai provider with
  the Codex-flavored request shape: `originator: codex_cli_rs`,
  `chatgpt-account-id: <claim>`, and a branded User-Agent. The factory
  branches off the catalog id (not the provider kind) so other
  openai-compatible providers keep the standard openai path unchanged.
- The openai provider gained a `SetRequestExtra` callback so the Codex
  wrapper can inject per-request headers without coupling the openai
  provider to Codex.

CLI / TUI
- `zero auth chatgpt` is a one-shot login command (analog to
  `zero auth openrouter`); the TUI's OAuth chooser now lists both new
  providers automatically (the list is built from
  `providercatalog.OAuthProviders()`).
- The provider-wizard visible-row cap was bumped from 8 to 10 so the
  common providers (OpenAI, Anthropic, Google, Ollama, OpenRouter, the
  new Hugging Face, the new ChatGPT, Groq, …) all fit without scrolling
  the test fixtures.

Tests
- `internal/oauth/presets_test.go`: presets resolve correctly with the
  expected endpoints, scopes, and flows; env overrides win; Hugging Face
  preset stays inert without a client_id (the safety posture the existing
  xAI tests assert).
- `internal/providercatalog/oauth_test.go` + `catalog_test.go`: catalog
  now exposes 4 OAuth providers (`openrouter`, `huggingface`, `chatgpt`,
  `xai`); the `chatgpt` descriptor is `OAuth=true` with
  `OAuthDeviceFlow=false` (Codex is loopback-only) and `RequiresAuth=true`
  via an inline IIFE that sets it after the openAICompat helper.
- `internal/provideroauth/chatgpt_test.go`: ID-token claim extraction
  round-trips (happy path, missing claim, missing token, tampered JWS,
  non-string claim); the full login flow runs against a stub auth server
  and verifies the preset's client_id reaches the token endpoint.
- `internal/providers/openai/codex_test.go`: every request gets the three
  Codex headers; the 401-refresh retry path keeps them on the second
  attempt; configured baseURL wins; default originator is `codex_cli_rs`;
  branded User-Agent wins over the openai default; AccountResolver is
  consulted when AccountID is empty; the header is omitted when the
  resolver says no.

Out of scope (separate PRs): multi-account / profiles, generic
template-driven OAuth wizard, MCP / provider OAuth store unification,
subscription-proxy autoconfig.

* fix(ci): gofmt chatgpt_test.go and provider_wizard.go

The ubuntu smoke job's "Check formatting" step lists these two files as
unformatted (struct field alignment). The local gofmt run on Windows
also lists ~170 other files, but those are CRLF-vs-LF noise from
checkout and not real gofmt issues on Linux; the CI only flags the
two struct-alignment changes below.

- internal/provideroauth/chatgpt_test.go: align chatgptTestServer fields
- internal/tui/provider_wizard.go: align ChatGPTOptions literal fields

* fix(codex): hit the /responses path and resolve account id per request

Addresses the two findings in anandh8x's CHANGES_REQUESTED review on #245.

The Codex provider previously routed the chat-completions body to
{baseURL}/chat/completions, which is not the path the Codex backend serves
(chatgpt.com/backend-api/codex/responses, the Responses API). Add an
Endpoint field to openai.Options so a flavor can target a sibling path on
the same host; the Codex constructor sets it to {baseURL}/responses and
falls back to the openai transport unchanged for everything else.

The factory was also passing the OAuth token's Account field as a static
AccountID at construction time. A refresh that rotates the token (and
its account claim) would leave a stale value on the wire. Drop the
static AccountID from the factory wiring; the per-request
AccountResolver (which reads the live store) is now the sole source, so
a refresh takes effect on the next outgoing request.

Tests:
- codex_test.go: handler mounted on /responses; expected path updated;
  TestCodexProviderResolverIsConsultedOnEveryRequest pins the per-request
  resolver behavior (a refresh-style sequence of calls picks up the new
  account id on the second attempt).
- factory_test.go: expected request path updated to /responses.

* Addresses the Codex path shape on /responses.

The previous fix (2381197) corrected the URL and the per-request account
resolver, but the Codex provider still spoke chat-completions: it sent
{model, messages, tools, stream, stream_options, max_completion_tokens}
to /responses and parsed data: [DONE]-terminated SSE frames
(choices[].delta). The Codex backend at chatgpt.com/backend-api/codex
serves the Responses API — input items, function_call /
function_call_output, response.output_text.delta /
response.function_call_arguments.delta events — and rejects a
chat-completions body.

The Codex provider now has its own request/stream path that matches the
Responses schema:

- internal/providers/openai/codex_responses.go (new) holds the wire
  types (responsesRequest, inputItem, contentItem, responsesTool,
  responsesEvent, itemPayload, responsePayload, usagePayload), the
  request builder (system → message/role=system, user/assistant →
  message with text or content parts, prior tool calls → function_call,
  tool results → function_call_output, tools → responsesTool), the
  Responses SSE dispatcher, the tool-call accumulator
  (response.output_item.added registers the call id + name, the
  argument deltas accumulate, response.output_item.done finalizes),
  and the terminal-event handler (response.completed emits usage +
  done, response.failed surfaces the error after the usage chunk so
  token accounting is preserved).

- internal/providers/openai/codex.go: StreamCompletion now marshals a
  Responses request and dispatches via the new streamResponses
  function. The wrapped openai Provider is still constructed for its
  validated endpoint / auth / retry / idle-timeout config and its
  SetRequestExtra callback, but the openai chat-completions stream
  parser is no longer used for Codex. injectCodexHeaders still runs
  on every attempt (including the 401-refresh retry) so the Codex
  headers stay attached to the rotated bearer.

The shared providerio plumbing (auth + 401-retry, SSE scanner with
the idle watchdog, error humanization, secret redaction) is reused
verbatim so the OAuth 401-refresh and bearer-rotation paths stay
identical to the rest of the openai-compatible surface. The
stream-end fallback surfaces a StreamEventDone with
FinishReasonLength when the Codex backend closes the stream without
a response.completed (e.g. an internal truncation), so the runtime
can react instead of hanging on a phantom completion.

Tests:
- internal/providers/openai/codex_test.go:
  - newCodexTestServer now returns a minimal Responses sequence
    (response.created + response.completed); newCodexResponsesServer
    takes a custom payload sequence for richer cases.
  - The two tests with inline handlers (TestCodexProviderResolverIs-
    ConsultedOnEveryRequest, TestCodexProviderRetriesHeadersAfter401)
    use a response.completed payload on the second attempt instead of
    data: [DONE].
  - TestCodexProviderSendsResponsesRequestShape replaces the old
    TestCodexProviderSendsRequestBody and pins the Responses shape:
    the body MUST carry an `input` array of message / function_call
    / function_call_output items and `tools` of function type, and
    MUST NOT carry the chat-completions `messages` field.
  - TestCodexProviderParsesResponsesTextDeltas: response.output_text.
    delta events surface as StreamEventText in order, the
    response.completed usage chunk surfaces as StreamEventUsage
    (with input_tokens, output_tokens, cached_input_tokens, and
    reasoning_tokens from the optional details blocks), and
    StreamEventDone follows.
  - TestCodexProviderParsesResponsesToolCalls:
    response.output_item.added emits StreamEventToolCallStart with
    the right name, response.function_call_arguments.delta events
    emit StreamEventToolCallDelta in order, response.output_item.done
    emits StreamEventToolCallEnd.
  - TestCodexProviderSendsAssistantToolCallsAsInputItems: a runtime
    message with content + tool_calls serializes as BOTH the
    assistant message and a function_call item; a tool result
    serializes as a function_call_output. The expected count is 5
    items (user + assistant text + function_call + function_call_
    output + user) — earlier this test had 4, which would have
    missed the assistant message before the function_call.
  - TestCodexProviderEmitsErrorOnResponseErrorEvent: a response.error
    event surfaces as a single StreamEventError with the server's
    message and stops the scan.
  - TestCodexProviderEmitsErrorOnMalformedStream: a payload that
    parses as JSON but lacks the `type` field is reported as a
    stream error rather than silently dropped.
  - TestCodexProviderEmitsLengthFinishWhenStreamEndsWithout-
    Completion: a stream that closes without a response.completed
    surfaces a StreamEventDone with FinishReasonLength.

Verification:
- `go build ./...` clean (with the user-owned untracked files moved
  aside per the project's working-tree convention).
- `go vet ./internal/providers/...` clean.
- `go test ./internal/providers/... ./internal/providercatalog/...
  ./internal/provideroauth/... ./internal/oauth/...` PASS.
- `gofmt -l` on the three changed files clean.

Bash permission prompts can now expose a validated session-scoped prefix approval. Prefixes are parsed from simple shell commands or an explicit prefix_rule argument, with redirects, control operators, assignments, expansions, globs, and broad launcher prefixes rejected before the option is shown.

KRATOS 1f92b25e8c sessions: make the events log authoritative for sequencing + fsync checkpoints/rewind (#251)
Two data-integrity gaps in the session store:

1. Sequence numbers were derived from metadata.EventCount, which is persisted
   AFTER the event line (a separate file). A crash between the two writes left
   EventCount behind the log, so the next append reused a sequence number -- a
   duplicate id that mis-targets /rewind (findRewindTarget returns the first
   match). Now the next sequence is derived from the events log itself
   (lastEventSequence, an O(1) tail read that ignores a torn trailing partial),
   so a stale/desynced EventCount can never cause a reused number; it falls back
   to the metadata count only if the log is unreadable.

2. Checkpoint blobs and rewind restores used plain WriteFile+Rename with no
   fsync, while session metadata fsyncs the temp file AND the parent dir -- so
   the /rewind safety net and restored workspace files were not crash-durable.
   They now go through the same writeFileSync + syncDir barrier
   (writeFileAtomicSync), preserving the exact-perm chmod on restore.

Tests: stale-low metadata -> no duplicate (the reported repro); stale-high ->
benign gap; lastEventSequence over empty / multi / torn-tail / large-event logs.

KRATOS a4279662b9 redaction: catch compound secret keys + non-bearer auth schemes; stop scanner over-redaction (#249)
* redaction: catch compound secret keys + non-bearer auth schemes; stop scanner over-redaction

Hardens the secret-redaction last line of defense after an audit of
internal/redaction + internal/secrets.

1. Compound secret keys are now redacted. IsSensitiveKey was exact-match only, so
   db_password, session_secret, stripe_secret_key, auth_token, csrf_token,
   ssh_private_key, backup_api_key, etc. passed through in cleartext. A new
   keyLooksSensitive applies conservative structural heuristics (secret /
   password / passphrase / credential / apikey segments; a singular trailing
   "_token"; api_key / private_key pairs). Critically, the agent's token-COUNT
   fields (max_tokens, prompt_tokens, token_count) and ordinary *_key fields
   (primary_key, public_key, cache_key) are deliberately NOT redacted.

2. Authorization headers with non-bearer/basic schemes were leaking. The header
   pattern now also covers token, apikey, digest, negotiate, oauth, and
   aws4-hmac-sha256.

3. The secrets scanner over-redacted ordinary text: its prefixed patterns (sk-,
   gh*, AIza, AKIA, xox, github_pat, jwt) lacked the word boundaries that
   internal/redaction already uses, so kebab-case words like
   "task-management-and-coordination" matched as a fake key. Added \b anchors.

Design note: a free-text "key: value" colon pattern was prototyped but dropped --
it mangled "file.go:line: message" output (a filename's "secret" segment looked
like a sensitive key), the same over-redaction class fix #3 addresses. The
structured paths (RedactValue for maps/structs, plus assign/JSON/query forms in
RedactString) are covered; free-text colon-form remains out of scope.

Tests: compound-key + token-count-safety matrix, auth-scheme redaction, the
file:line guard, and scanner boundary positives/negatives.

* redaction: redact the full auth-header value for multi-part schemes

The broadened header pattern captured only the first token after the scheme, so
parameterized schemes (Digest "…, response=…", AWS4-HMAC-SHA256 "…, Signature=…")
left the actual secret param visible. Redact the entire value to end of line; the
scheme name is kept. Adds tests with realistic Digest + AWS SigV4 headers.

Addresses review feedback.

Anandan 2cf6fd2334 Add request permissions flow (#248)
* Add request permissions flow

Adds a runtime-handled request_permissions tool that can ask for turn or session filesystem/network grants and return the granted profile as structured JSON.

Temporary turn grants update the shared sandbox scope and effective policy, then clean up at run end; session grants persist in memory for the session.

Read grants now stay read-only through tool path resolution, policy evaluation, and native sandbox profile construction.

The TUI renders request_permissions with grant-specific choices, including strict review, and Esc continues without granting permissions.

Tested: GOCACHE=/tmp/zero-go-cache go test ./...

* Align request permission grants with prompts

Display and return the normalized grant roots that the sandbox actually applies, so file-like permission requests no longer show a narrower path than the directory root being granted.

Also makes the network prompt explicit about all outbound access and relabels the strict option as a model review request instead of implying enforced command review.

KRATOS 995b9086c7 feat(subagent): proactive specialist delegation + swarm execution fixes (#243)
* feat(subagent): proactive specialist delegation + swarm execution fixes

Fixes:
- Task tool dropped the parent's permission mode, so every delegated
  sub-agent ran at --auto high regardless of the parent. Forward
  PermissionMode so a child never exceeds its parent's authority.
- Swarm members never executed: swarm_spawn accepts agent types
  teammate/subagent, but the launcher looked those up as specialist names
  (only worker/explorer/code-review exist), so every member failed with
  "specialist not found". Run each member from its swarm definition via an
  inline manifest on the executor.

Enhancements:
- Auto-delegation: the orchestrator system prompt now lists the available
  specialists and when to use each, nudging it to offload read-heavy work to
  a sub-agent so large tool output stays out of the main context.
- @-mention: a leading "@<specialist> <task>" in the TUI composer delegates
  to that specialist (transcript keeps the verbatim mention); the @ palette
  suggests specialists on the first token, file references mid-message.
- swarm.maxTeamSize config caps concurrent members per team (0 => default 8;
  negative rejected), honored in user and project config.
- Proactive spawning: read-only specialists (explorer/code-review) auto-
  approve via a new args-aware tool permission (tools.ArgsPermissioner), so
  the agent delegates exploration off a normal prompt without an approval
  prompt; write-capable specialists, resume, and unknown names still prompt.
  The exec gate registers specialist tools at medium/high autonomy so a
  non-trivial headless run can auto-delegate read-only too.

* fix(specialist): fail-safe child autonomy when PermissionMode is unset

specialistAutonomy mapped an empty PermissionMode to "--auto high" (unsafe),
silently re-introducing the privilege escalation the rest of this PR fixes: an
orchestrator that forgets to wire PermissionMode would get an unsafe child. The
Task tool and swarm both now propagate a resolved mode, so "" only occurs for a
caller that omitted it -- default that case to "low".

Only an explicit unsafe parent now yields --auto high; everything else (incl.
unset/unknown) is fail-safe low. Updates the stale "back-compat" comments and the
tests that documented the old behavior.

Addresses the non-blocking follow-up from PR review.

KRATOS 4582727f95 tui: image-input UX — drag-drop attach, inline numbered chips, vision fallback, cursor + copy fixes (#247)
* tui: image-input UX — drag-drop attach, inline numbered chips, vision fallback, cursor + copy fixes

Improves the image/PDF attachment flow and two long-standing composer papercuts.

- Drag-and-drop: dropping an image/PDF onto the composer attaches it instead of
  erroring as an unknown "/…" command. The dropped path is detected on paste and
  on submit (absolute/escaped/quoted paths to an existing image or PDF).
- Inline numbered chips: staged attachments render as compact [Image #1] /
  [Doc #1] chips INSIDE the input box; the verbose "Attached … (image/png)"
  system line is dropped. Backspace on an empty composer removes the last chip
  (/image clear still drops all).
- Vision fallback: a real multimodal model absent from the curated catalog
  (custom / openai-compatible / local ids) now accepts images via a conservative
  name match; text-only ids stay refused, and the catalog stays authoritative.
- Blinking composer cursor, including when the box is empty (previously no caret
  was drawn for a focused, empty box).
- Ctrl+E releases/recaptures the mouse so native drag-select + copy works (mouse
  capture otherwise intercepts terminal text selection).

Tests: dropped-path detection, vision-by-name + unknown-model fallback,
mouse-release capture toggle, attachment removal, and updated chip-render tests.

* fix(vision): a "vision-less" model name must not match the bare-vision fallback

visionCapableByName treated any id containing "vision" as multimodal, so a model
named "...vision-less..." (i.e. WITHOUT vision) was wrongly classified vision-
capable — which silently skipped the non-vision image gate and broke
TestRunExecDropsImagesOnNonVisionModelWithWarning in internal/cli.

Add mentionsVision, which still matches the "vision" word but excludes the
negated forms (vision-less / visionless / no-vision / non-vision). Used for both
the grok-vision and the general open-multimodal fallback. Added negation cases to
the name table.

* fix(tui): drag-drop path detection corrupted Windows paths (backslash unescape)

unescapeDroppedPath stripped backslashes to undo Unix terminal drag-drop escaping
("\ " -> " "), but on Windows the backslash is the path separator, so a plain
dropped path like C:\Users\x\file.png became C:Usersxfile.png and never resolved
-- TestDroppedAttachmentPath failed on windows-latest.

No-op the unescape on Windows (dropped paths there arrive quoted or plain), and
gate the Unix-only backslash-escaped positive case behind runtime.GOOS.

KRATOS b903825139 perf(tools): lower default deferThreshold to stop eager MCP-schema token waste (#241)
* perf(tools): lower default deferThreshold 10 -> 3 to stop eager MCP-schema waste

MCP tool schemas are only collapsed into compact tool_search reminder lines once
the deferred-eligible tool count reaches tools.deferThreshold. The default of 10
meant a typical single MCP server (Exa-style, a handful of tools) stayed BELOW it,
so every full MCP schema — 300-600 tokens each — was re-sent on every turn, even
for a one-word message. A small MCP set could add several thousand input tokens
per message.

Lower the default to 3 so a normal MCP server's toolset defers and stays cheap.
Capability is unchanged: every tool is still reachable; the model just loads a
deferred tool's schema via tool_search before its first use, after which it is
loaded for the rest of the run. Fully overridable via tools.deferThreshold
(0 keeps the old always-eager behavior for models without tool_search).

* test(agent): measure the deferral token saving (66% smaller tool payload)

* fix(tokens): count non-whitespace bytes so estimates match the real tokenizer

The token estimate was naive len/4, which overcounted by ~15-20%: `zero context`
reported ~6k for a prompt the provider's tokenizer actually counted as 5,203.
BPE tokenizers (the ones zero targets) fold a run's leading space into the
following token rather than emitting whitespace separately, so counting
NON-whitespace bytes / 4 tracks the real count closely (now ~5.2k, ~1% off the
measured 5,203) while staying dependency-free.

Add agent.ApproxTextTokens and route the context-budget preview
(contextreport), the compaction threshold (agent), and the TUI transcript
estimate through it so every surface uses one accurate scale. The provider's
exact usage is still authoritative on each request; this only sharpens the
pre-request preview and compaction timing.

Anandan a1b9bbb07c Align permission prompts for web tools (#242)
Treat hosted web_search as an allowed read-only network discovery tool so normal searches do not stop on a permission prompt, while retaining sandbox network enforcement when tool-network policy is enabled.

Add host-scoped persistent grants for web_fetch URLs so an always-allow decision is bounded to the requested host instead of becoming a blanket tool-wide fetch grant.

Update permission prompt and transcript rendering to show network targets, scoped always labels, and preserved scope metadata across live rows, render caching, and session hydration.

* Route Linux sandboxing through helper

Move Linux command planning to invoke zero-linux-sandbox with the permission profile, command cwd, and command argv instead of exposing bubblewrap construction from the runner boundary.

The helper now builds the bubblewrap argv, binds its own executable for the inner stage, applies the seccomp/no-new-privs step before exec, and preserves the original command cwd path.

Package Linux releases with zero-linux-sandbox next to zero so release builds use the helper directly, while local development can fall back to go run for the helper.

Derive a deterministic Windows ACL operation list from the restricted permission profile, including writable root allows, protected metadata deny-write entries, explicit deny-write paths, and deny-read materialization targets.

KRATOS c0fedade8d feat: free out-of-the-box web (keyless Firecrawl default) + resilient MCP startup (#239)
* fix(mcp): skip an unreachable MCP server at startup instead of aborting

RegisterTools connected to every server eagerly and failed the whole batch if any
server could not be reached or list its tools — and the caller aborts startup with
exit 1 on that error. So a single unreachable MCP server prevented zero from
launching at all and disabled every other (working) server.

Make registration best-effort across servers but still atomic within a server:
each server's tools are validated as a unit before anything commits, and a server
that cannot be connected, returns a nameless tool, or conflicts is SKIPPED —
recorded on Runtime.Skipped(), not fatal. The caller surfaces each skip as a
warning and keeps launching. The "no dead tools" and no-partial-tool-set
guarantees are preserved.

* feat(mcp): ship keyless Firecrawl as a default web search/scrape server

Seed an enabled-by-default Firecrawl MCP server (keyless: 1,000 free credits/month,
no API key, no setup) into ResolveMCP before user/project config is merged, so web
search and scraping work out of the box for open-source users. A user can override
any field (self-hosted URL, bring-your-own-key header) or disable it entirely;
`zero mcp disable firecrawl` writes the override even though the default lives in
code rather than the config file.

The built-in web_fetch tool stays the always-local floor. Firecrawl is AGPL-3.0,
but zero only calls it over the network, so the license never reaches zero's own
code. README documents disable / self-host / bring-your-own-key / the privacy note
that keyless routes through firecrawl.dev.

Depends on the resilient-startup change: on an offline machine the default is
skipped with a warning, not fatal.

* perf(mcp): connect MCP servers concurrently with a per-server startup timeout

RegisterTools connected servers serially with a 30s handshake timeout, so startup
waited for the SUM of all servers and one slow/unreachable server (e.g. a hosted
endpoint blocked by the local network) blocked every other server AND the first
model response — often 10-30s of dead time per launch.

Connect all servers CONCURRENTLY, each bounded by a per-server ConnectTimeout
(default 8s). A server that doesn't connect+list in time is abandoned (its context
cancelled to tear down the half-open connection/subprocess) and skipped, so total
startup cost is now the slowest REACHABLE server, not the sum. The concurrent
phase does only connect+list (no shared state); validation, conflict detection,
and registration stay in a deterministic serial phase, so the outcome is identical
regardless of completion order. A kept server's context is released at Close — a
stdio subprocess is tied to its context, so it must outlive the connect.

Pairs with the resilient skip-on-failure behavior already in this branch.

Vasanth T 7d66942564 docs: rewrite AGENTS.md as user-facing 'Extending Zero' guide (#237)
* docs: rewrite AGENTS.md as a user-facing 'Extending Zero' guide

The previous AGENTS.md (a 19-line Go-specific instruction set) was replaced
with a user-facing extension guide for Zero as an open-source CLI agent
product. Covers:

- Project-level AGENTS.md (where to drop one, format, tips)
- Custom specialists (droids): scopes, manifest format, CLI
- Skills: discovery, SKILL.md format, ZERO_SKILLS_DIR override
- Hooks: lifecycle events, JSON config locations, exit code semantics
- MCP: as client (config.json mcp.servers) and as server (zero serve --mcp)
- Plugins: plugin.json manifest, install/enable/disable/remove
- Configuration locations: built-in < user < project < CLI < env
- End-to-end example: what a team commits vs what a contributor adds
- Reference links to README and docs/SPECIALISTS.md, docs/PRD.md, etc.

This positions AGENTS.md as the entry point for end users who want to
customize Zero, mirroring the role that similar files play in Claude Code
and Codex.

* docs(AGENTS): align Extending Zero with actual loader behavior + D-style features

Fix six claims that were wrong about Zero itself, document the new
upward path-walking the loader now does, and surface three roadmap
gaps in the relevant sections.

What changed in the doc:
- Section 1 (Drop a project AGENTS.md): rewrote the file table to
  match the real priority order [AGENTS.md, ZERO.md, .zero/AGENTS.md]
  and added the case-insensitive basename callout (git tracks
  AGENTS.MD uppercase on case-sensitive filesystems).
- Section 1: documented the per-file (8 KiB) and total (32 KiB) caps
  and the eager-load + restart-required caveat.
- Section 1: added the monorepo tip and the path-walking explanation
  ("walks from cwd up to git root, general-to-specific order").
- Section 2 (Custom specialists): added a roadmap note about the
  planned /droids in-UI manager.
- Section 3 (Skills): corrected the discovery-root chain
  (ZERO_SKILLS_DIR -> XDG_DATA_HOME/zero/skills -> ~/.local/share/zero/skills),
  noted that project-level skills aren't supported yet, and called
  out the plugin-declared-skill gap.
- Section 4 (Hooks): roadmap note about the planned /hooks in-UI
  manager.
- Section 6 (Plugins): roadmap note about the planned /plugins in-UI
  manager; cross-link to the skills gap.
- Frontmatter globs broadened to include *.json / *.toml / *.yaml /
  *.yml, matching the actual file types Zero reads.

* feat(agent): make AGENTS.md loader case-insensitive + add path-walking

Two changes to the project guideline loader that bring Zero closer
in line with D's DynamicContextDiscovery and fix a real bug.

1. Case-insensitive basename matching. The git-tracked filename is
   AGENTS.MD (uppercase MD), but the loader was looking for AGENTS.md
   (lowercase md). On a case-sensitive filesystem (Linux, the WSL
   filesystem, or a CI runner) this means the file was invisible to
   the loader. The new findProjectContextFile uses ReadDir + ToLower
   to resolve the on-disk filename and matches AGENTS.MD, Agents.md,
   agents.md, etc. to the same entry. On Windows/macOS the visible
   filename in the prompt label is now the actual on-disk name
   (AGENTS.MD), not the lookup name.

2. Upward path-walking. The loader previously did a single
   first-match-wins lookup at cwd. The new projectGuidelines walks
   from cwd up to the nearest git root, finds the first matching
   project context file at each level, and injects them in
   general-to-specific order (git root first, cwd last). A monorepo
   with a root AGENTS.md and per-service AGENTS.md files now sees
   both, with the most specific rules last. This mirrors what D
   does per-Read on the dynamic path, just at session start.

Cap behavior:
- Per-file cap is unchanged: 8 KiB.
- New total cap of 32 KiB across all matched files, enforced via a
  rolling counter; when the budget is exhausted, further files are
  dropped (and the per-file limit is the lesser of the per-file cap
  and what's left of the total).
- Truncation marker is unchanged: \n… (truncated).

New helpers and tests:
- projectGuidelineDirs / projectGuidelineLabel / findProjectContextFile
  / resolveDirCaseInsensitive / findProjectGitRoot.
- 8 new tests covering case-insensitive matching, monorepo
  path-walking, ZERO.md fallback, .zero/AGENTS.md fallback, total
  cap truncation, and the helper functions.

Existing TestBuildSystemPromptInjectsWorkspaceContext still passes;
the label for a single-file repo is still AGENTS.md / AGENTS.MD as
appropriate to the on-disk name.

* docs(AGENTS): drop syntax that doesn't exist in the current code

Per the review on #237, the previous "Extending Zero" guide documented
several commands, flags, and conventions that the runtime does not
implement. Concretely:

- `zero plugins install` / `enable` / `disable` are not subcommands.
  `runPlugins` (internal/cli/extensions.go) only dispatches
  `list` / `add` / `remove`(`rm`). Replace the example with `add` and
  note that enable/disable are not CLI verbs today (the plugin is
  enabled by being present and disabled by being removed, or by
  setting `"enabled": false` in its manifest).

- `zero specialist create ... --prompt-file api-reviewer.md` is wrong:
  there is no `--prompt-file` flag. `runSpecialistCreate` takes the
  prompt inline via `--prompt`. Show a `$(cat ...)` shell substitution
  as the practical way to load a file, and add `zero specialist path`
  to the example.

- `"Authorization": "Bearer ${env:GITHUB_TOKEN}"` implies env-var
  expansion that does not exist: MCP header values are sent verbatim
  (internal/mcp/permissions.go, client.go mergeProcessEnv). Use a
  literal placeholder and document the three real ways to keep the
  token out of the file (wrapper script, command substitution, server
  reading its own env).

- Hook `args: ["${tool}", "${input}"]` is the same mistake plus a
  shape mismatch: the actual hook payload (event, matcher, tool call
  id, tool input/output, status) is delivered as JSON on stdin
  (internal/hooks/dispatch.go `execCommandRunner`), not via `${...}`
  substitution. Drop the placeholders, add a short bash handler that
  reads stdin, and show the `args` field as verbatim CLI args.

- "use `zero doctor` to surface them" — the doctor backend
  (internal/doctor/doctor.go) has no hook check; its checks are
  runtime / config / provider / connectivity / sandbox / lsp.
  Reword to point at the audit log instead.

Secondary: drop the `globs:` and `alwaysApply:` example and the
"Use globs: to scope which files the rules apply to" tip — the loader
injects the whole file (frontmatter included) as prompt text and does
not parse those keys. Add a one-liner noting the frontmatter is
preserved verbatim. Also drop the parenthetical "(droids)" on
§2 to match the "specialists" terminology the rest of the codebase
(and the CLI) actually use, and reword the §2/§4/§6 roadmaps that
promised in-UI managers via non-existent `/droids`, `/hooks`,
`/plugins` slash commands.

KRATOS 29fc29a41d feat: add providers detect and sandbox check (wire audit-found unwired features) + coverage (#238)
* feat(providers): add `zero providers detect` for local-runtime onboarding

Wire the previously-unwired provideronboarding detect/advice surface into the
CLI. `zero providers detect` probes for running local OpenAI-compatible runtimes
(Ollama, LM Studio) on their default ports and prints a no-key adopt command for
each, followed by the next-step actions (use / check / set key) for every
configured provider. Supports --json.

This connects DetectLocalRuntimes, LocalRuntimeCandidates,
DetectedLocalRuntime.SetupAction, ProviderActions, MissingCredentialAction,
SetupCommand, and ProviderState.Actions — a fully built, tested feature that had
no caller. Adds an injectable detectLocalRuntimes appDep for hermetic tests.

* feat(sandbox): add `zero sandbox check` to evaluate a decision as JSON

Wire the previously-unwired zerocommands sandbox-snapshot contract into the CLI.
`zero sandbox check <tool>` evaluates what the sandbox engine would decide for a
hypothetical tool action against the resolved policy, and emits the active plan
(policy + backend + restrictions), the decision (allow/prompt/deny with risk and
any violation), and any persistent grant matching the tool. Supports --json;
grant reasons are redacted.

This connects SandboxPlanSnapshotFromPlan, SandboxPolicySnapshotFromPolicy,
SandboxBackendSnapshotFromBackend, SandboxDecisionSnapshotFromDecision,
SandboxRiskSnapshotFromRisk, SandboxViolationSnapshotFromViolation, and
SandboxGrantMatchSnapshotFromLookup — a fully built, tested JSON contract that
had no production consumer. The existing `sandbox policy` output is unchanged.

* test(providermodelcatalog): cover model predicates and remote fetch layer

Add targeted tests for the audit-identified coverage gaps: the pure logic
(LooksLikeCodingModelID, modelMatchesProvider, defaultedOpenGatewayURL,
modelSortLabel/sortModels) and the HTTP fetch layer (fetchJSON, FetchModelsDev,
FetchOpenGateway, FetchRemote routing) via httptest. Package coverage 48.9% ->
79.5%. cmd/zero (main shim) and browser.OpenURL (exec wrapper) are intentionally
left to CI smoke — their only logic seams (openCommand) are already covered.

* fix(sandbox): address CodeRabbit review on `sandbox check`

- Pass the configured write-root scope (NewScope with AdditionalWriteRoots) into
  the check engine, so its decision matches real enforcement and a stale
  extra-root config surfaces here too instead of a workspace-only fallback.
- Validate --side-effect and --autonomy against their advertised value sets and
  return a usage error on a typo, rather than letting the engine normalize it.
- Reword the unmatched-grant line to "no grant matched this action" — Lookup only
  checks this tool/scope/autonomy, not whether any grant exists for the tool.
- Add tests: invalid-flag rejection and a matched-grant reason-redaction
  regression.

* test(sandbox): make the out-of-workspace check test path OS-portable

Smoke (windows-latest) failed: "/etc/passwd" is not absolute on Windows, so the
check joined it into the workspace and returned "prompt" instead of "deny".
Build the out-of-workspace path under a separate temp dir so it is absolute and
outside the workspace on every OS.

KRATOS 7c36805505 fix(providers): clear error when a model host is unreachable (#233)
* fix(providers): surface a clear error when a model host is unreachable

A local Ollama daemon serving a "-cloud" model answers on localhost but
returns HTTP 502 carrying an opaque proxied transport error (e.g.
`Post "https://ollama.com:443/...": net/http: TLS handshake timeout`) when it
cannot reach its own cloud backend. A direct hosted endpoint blocked by the
local network fails the same way at the transport layer. Both previously
surfaced as raw strings ("provider error:" / "provider stream error:") that
read like a zero bug and gave the user nothing to act on.

Add providerio.UpstreamUnreachable: it detects a transport-level connectivity
failure (TLS handshake timeout, context deadline exceeded, connection refused,
no such host, network unreachable, i/o timeout) bound to a concrete host and
rewrites it into an actionable message naming the host and explaining the
request never reached the model. It requires both a marker and a host, so the
agent's own request-deadline cancellations are left untouched.

Wire it into the OpenAI-compatible adapter's gateway-error and transport-error
paths, covering both the local daemon proxy and direct hosted providers;
secrets are still redacted. Covered by unit tests over the real error shapes
and an end-to-end 502 adapter test.

* fix(providers): don't humanize a caller-context timeout as an upstream outage

Address CodeRabbit review: in the OpenAI-compatible adapter's transport-error
path, a caller-driven cancel/deadline surfaces as an error string containing
"context deadline exceeded" plus the request host, which UpstreamUnreachable
would mislabel as "upstream unreachable" — the host is reachable; the caller's
clock ran out. Check the parent ctx.Err() first and surface it verbatim, so only
genuine connect failures (ctx still live) are humanized.

Adds a deadline regression test; the existing cancel test used Cancel, whose
"context canceled" is not a marker, so it never covered this path.

922a5bab5f feat(tui): Ctrl+T cycle + divider display for reasoning effort (#229)
* feat(tui): Ctrl+T cycle + divider display for reasoning effort

Reasoning effort was already fully wired (per-model supported lists,
DefaultReasoningEffort, the EffectiveReasoningEffort clamp, /effort and
/mode), but it was invisible in the UI and reachable only by typing a
command. Add the opencode-style one-key fast path:

- Ctrl+T cycles the active model's effort ring (auto -> low -> medium ->
  high -> auto), gated by the same modal condition shift+tab uses and a
  silent no-op on models with no effort controls.
- The composer divider shows the active effort in the brand lime when
  set; the segment is omitted on "auto", so its presence/absence is
  itself the auto-state feedback.

Zero per-frame registry lookups: the cycle runs only on the rare
keypress and the divider branches purely on m.reasoningEffort != ""
(DefaultRegistry rebuilds the whole catalog on every call, so it must
never be touched from the render path).

Tests cover every cycle branch (auto->first, mid-ring advance,
last->auto wrap, unknown->auto, no-op on unsupported model) and the
divider show/omit paths.

Co-Authored-By: Claude <[email protected]>

* fix(tui): address CodeRabbit review on Ctrl+T effort cycle

- Block Ctrl+T effort cycling inside the detailed transcript (matches the
  shift+tab gate) so state changes don't happen while the user is reading
  a frozen view.
- Use a guaranteed-unplaceable sentinel in the unknown-effort reset test
  instead of ReasoningEffortMinimal, so the test stays correct if Minimal
  becomes a supported ring level later.

* fix(tui): extract shared noBlockingModal() for shortcut gates

The 7-term modal gate was duplicated verbatim between the shift+tab and
Ctrl+T cases. Fold it into a single noBlockingModal() helper so the two
shortcuts can't drift the day a new modal is added to one and not the
other. Pure refactor, no behavior change.

Co-authored-by: factory-droid[bot] <138933559+factory-droid[bot]@users.noreply.github.com>

* fix(tui): hide divider effort segment on models without effort controls

The divider showed whatever m.reasoningEffort was set to, even when the
active model had no effort controls (e.g. gpt-4.1). Switching from
claude-sonnet-4.5 (low/medium/high) to gpt-4.1 would leave a stale
"high" floating in the divider even though it has no effect.

Make the segment selective: only render it when the active model exposes
availableReasoningEfforts, matching the same appearing/disappearing
state feedback the divider already uses for the auto case. The lookup
hits a hard-coded static catalog, not a per-frame rebuild, so it's
safe on the render path.

handleModelCommand already resets an unsupported effort preference on
model switch, so no changes are needed there.

Co-authored-by: factory-droid[bot] <138933559+factory-droid[bot]@users.noreply.github.com>

* fix(tui): drop model-aware effort gate in divider; /effort picker already selective

The previous commit added `&& len(m.availableReasoningEfforts()) > 0` to
the divider's effort-segment gate so a stale value couldn't be shown
after switching to a model without effort controls. Reverting that
change: the underlying state mutation is already gated elsewhere
(handleModelCommand clears an unsupported preference on switch, and the
/effort picker only opens for models that actually expose effort
controls), so the divider doesn't need its own check.

The /effort picker (newEffortPicker, pickerEffort kind) is already
fully wired and tested — /effort with no args on a supported model
opens the picker; on a model with no effort controls, the text path
returns "Active model does not expose reasoning effort controls."

Co-authored-by: factory-droid[bot] <138933559+factory-droid[bot]@users.noreply.github.com>

* fix(tui): open effort picker even when active model has no effort controls

Previously newEffortPicker returned nil for any model not in the hard-coded
catalog (e.g. ollama-cloud providers serving glm-5.1 or similar). The
case commandEffort dispatch fell through to handleEffortCommand, which
rendered a grey "Effort / status: warning / available: none for active
model" status card -- the very static panel users were reporting.

Now newEffortPicker always returns a picker: a single "auto" option when
the active model exposes no effort controls, or "auto" plus the model's
known efforts otherwise. handleEffortCommand already returns the "Active
model does not expose reasoning effort controls" message if any
non-auto value is later set, so no other gate is needed.

Co-authored-by: factory-droid[bot] <138933559+factory-droid[bot]@users.noreply.github.com>

* feat(tui): render description hint below composer for single slash match

Claude-code-style: when the user types a slash command that resolves to
exactly one command in the autocomplete palette, surface that command's
description on a muted line just below the composer box. Multiple
matches keep the existing dropdown as the right affordance; once the
user starts typing arguments the hint clears; the @file palette keeps
its own rows and the hint stays scoped to slash commands.

The inline argument hint ([low|medium|high|auto]) still renders inside
the composer box after the slash, so both UIs coexist.

Co-authored-by: factory-droid[bot] <138933559+factory-droid[bot]@users.noreply.github.com>

* feat(tui): render /effort output as a polished command card

The /effort command used to push its status text through renderCommandOutput,
which renders as a thin grey panel (faint text on panel background, neutral
border). Replace that path with renderCommandCardTranscript so the result
renders the same way as /tools, /mcp, /permissions, etc.: a lime-bordered
titled card with a key/value "State" section and a footer of next-step actions.

Three call sites updated:
- handleEffortCommand("auto") -> sets effort to auto, shows confirmation card
- handleEffortCommand(<value>) -> sets effort, shows confirmation card
- handleEffortCommand(<bad>) -> unknown / unsupported / not exposed -> shows
  the same card with the relevant detail line

effortText() (the no-arg / list / picker-dismiss path) follows the same
pattern. The "status: warning" line and grey panel are gone; the warning
case instead keeps the lime accent and surfaces "no reasoning controls on
this model" in the summary, matching the rest of the TUI's visual language.

KRATOS 6df5c2b4cb Improve /resume: interactive session picker + model-generated titles (#224)
* tui: interactive /resume session picker + resume fixes

- /resume (no arg) now opens an interactive picker like /model and /provider:
  one row per resumable session showing the title and session id (+ relative
  age); arrow to highlight, type to filter, enter to load. /resume <id> and
  /resume latest still resolve directly.
- Resume now loads the rehydrated (compaction-aware) event view instead of the
  raw log, so a resumed session honors a prior /compact — matching the CLI's
  `zero exec --resume` and the in-TUI /compact reload. Falls back to raw on a
  rehydrate error.
- The resume summary reports the model/provider the continuation will actually
  use (the active ones), noting the session's recorded model/provider when it
  differs, instead of implying a switch that doesn't happen.
- Drop the dead, self-contradictory resumeText(arg) branch (it was unreachable
  and its hint was circular); resumeText is now the no-session/error fallback.

Tests: session picker opens with title+id rows and hydrates on selection;
resume honors prior compaction (rehydrated, not raw events).

* tui: lead /resume picker rows with a precise timestamp

Same-titled sessions (e.g. the same first prompt run several times) looked like
duplicates because the row showed only the identical title plus a long id that
truncated the age away. Lead each row's label with a precise local timestamp
(HH:MM:SS today, "Jan _2 15:04" earlier this year, else the date) so distinct
sessions are obviously distinct; the full id stays as the right-aligned meta and
is what selection resolves. sessionWhen parses the RFC3339 UpdatedAt.

* tui: hide empty/no-output sessions from the /resume picker

Most of a heavily-retried prompt's sessions are empty failed runs — just the
prompt plus the no-output guardrail stop ("Agent stopped … with no output …"),
with no assistant text and no tool calls. They have nothing to resume and flood
the picker with identical-looking rows. Skip any session with no resumable
content (no tool call/result and no real non-user message) from the picker; they
stay on disk and are never deleted. Adds agent.IsNoProgressStop to recognize the
stop message from a recorded event, and a test that the picker hides an empty
run while keeping a real one.

* feat(tui): model-generated session titles (auto + /retitle backfill)

Sessions were titled from their first user message, so prompts that
started the same way (or empty/failed runs) looked identical in the
/resume picker. Generate a concise, specific title with the active
provider instead.

- sessions.Store.UpdateTitle(id, title): rewrites only Title under the
  per-session lock, re-reading the latest metadata first; leaves
  UpdatedAt untouched (a retitle is not activity and must not reorder
  the resumable list), rejects a blank title, and no-ops an unchanged
  one.
- Title generator: a bounded digest of the conversation (user/assistant
  text + tool names, per-message and total caps, skipping the no-output
  guardrail stop) is sent as a one-shot completion; the response is
  cleaned (first content line, quotes/markup/"Title:" label stripped,
  word- and rune-capped) before storing.
- Auto-title going forward: after a successful turn, a session still
  carrying its default first-message title gets a title in the
  background, at most once per session.
- /retitle: backfills existing resumable sessions that still have a
  first-message title, one at a time, skipping empty/failed runs and
  already-named sessions, with kickoff and completion status lines.

Generation runs off the Update goroutine; failures are non-fatal (the
first-message title simply stays). Adds store + TUI unit tests
(UpdateTitle semantics, digest/cleaning, auto-title one-shot, backfill
candidate selection). gofmt/vet/build(host+linux+windows)/test -race/
staticcheck all green.

* address review: tighten no-progress detection, fix fallback errors + nil guard

Three review findings on the /resume work:

- IsNoProgressStop matched any content CONTAINING the no-output marker
  substring (strings.Contains), so a legitimate assistant/tool message that
  quoted the marker could be misread as a failed empty run — wrongly hiding a
  real session from the /resume picker and skipping its title generation. Now
  it requires the full answer structure (prefix + marker + suffix); a quote no
  longer matches.
- resumeEvents returned the earlier rehydration error when the raw ReadEvents
  fallback itself failed, masking the actual fallback failure. Returns rawErr.
- resumeText dereferenced m.sessionStore unconditionally; a nil store (fallback/
  test paths) would panic. Now renders a safe "store unavailable" message.
  (newSessionPicker already guarded nil.)

Tests: IsNoProgressStop accepts the real answer and rejects a quoting message /
bare marker / prefix- or suffix-only; resumeText with a nil store returns the
safe message instead of panicking. Full gate green.

* address review (Vasanth): structural no-progress check, retryable auto-title, nil-store guard, deep resume assertion

- guardrails: IsNoProgressStop now matches the exact structure noOutputStopAnswer
  emits — prefix + "<int> turns " + marker + " " + suffix — instead of
  prefix && contains(marker) && suffix. A genuine message that merely quotes the
  marker amid other prose is no longer misclassified as a failed empty run (which
  would wrongly hide a real session from /resume and skip its title generation).
  Adds the hostile-input regression cases (quoted marker, text between
  marker/suffix, non-integer turn count).
- session_title: release the optimistic titledSessions gate when a generation
  FAILS (provider error, empty title, store write error) so a later turn or
  /retitle can retry; success keeps the one-shot gate. Kept the optimistic mark
  (rather than mark-on-success) to preserve the no-double-fire guarantee while a
  generation is in flight.
- session_title: guard maybeAutoTitleActiveSession against a nil sessionStore
  (the title cmd calls store.UpdateTitle) — mirrors the resume nil-store guards.
- model_test: assert resumed sessionEvents with reflect.DeepEqual against the
  rehydrated context, not just slice length, so a reordered/substituted-but-
  same-length regression is caught.

KRATOS b7f90a787f tui: right-click pastes the clipboard directly (no menu) (#231)
* fix(tui): right-click pastes the clipboard directly (no menu)

A right-click now pastes the OS clipboard straight into the focused input —
composer, provider/MCP wizard, or setup — with no context menu, mirroring the
bracketed-paste behavior. Keyboard and selection copy/paste are unchanged.

- clipboard.go: pasteFromClipboardCmd reads the clipboard off the Update
  goroutine; routePaste is the shared router for both bracketed paste (PasteMsg)
  and right-click paste (clipboardReadMsg), so the two behave identically.
- mouse.go: a right-click returns pasteFromClipboardCmd; input_compat.go adds the
  mouseRightPress helper.
- model.go: PasteMsg now routes through routePaste; clipboardReadMsg inserts on
  success or shows a brief "Paste failed" status when the clipboard can't be read
  (e.g. no clipboard utility on a remote session).

Tests: right-click returns the read command (chat + wizard), clipboard content
routes to the focused field, read errors surface a status, empty is a no-op.

* fix(tui): right-click paste in setup mode + scope the paste test

Setup mode routes mouse events to handleSetupMouse, which only handled
left-click and wheel — right-clicks were swallowed, so paste never fired
during onboarding. Add the same mouseRightPress -> pasteFromClipboardCmd
branch handleMouse uses; routePaste already targets the setup field.

Test: assert the right-click contract at handleMouse/handleSetupMouse
scope instead of via Update (which batches unrelated commands and masks a
regression), and cover the new setup-mode path.

Addresses review on #231: mouse.go (setup paste, critical) and
clipboard_test.go (weak Update-level assertion, minor).
2026-06-17 11:53:39 +05:30
KRATOS b1cf24831d fix(tui): selectable + clickable permission popup (#232)
The permission prompt now has a moving cursor and clickable options, on top of
the existing a/y/d hotkeys (which still resolve directly):
- ↑/↓ and Tab/Shift+Tab move the highlight across allow once / always / deny
  (resting default: allow once); Enter confirms the highlighted option.
- each option is rendered on its own row, and a left-click on a row resolves
  that choice directly.

- permission_prompt.go: permissionOptions + cursor move/clamp/confirm helpers.
- model.go: pendingPermissionPrompt gains a cursor; Enter confirms it, ↑/↓/Tab
  move it; a/y/d are unchanged.
- rendering.go: renderFocusedPermissionPrompt renders per-option rows with the
  cursor highlighted (▸ + reverse label) and returns each option's card-relative
  Y offset so the caller can register clickable rows.
- transcript_selection.go: transcriptSelectableLine gains permOption/permChoice;
  the pending-permission item registers each option row as clickable, and a
  left-click on one resolves the permission.

Tests: cursor default/move/wrap, Enter confirms the highlight, hotkeys still
resolve directly, render emits highlighted clickable offsets. Existing card/
submit-block tests updated for the new per-option layout + Enter-confirms.

Anandan 0b496ce87d Render transcript viewport from measured items (#227)
Add a bounded per-model transcript body height cache keyed by the existing row render fingerprint, then use measured spans to render only the visible alt-screen item window instead of building the full body string every frame.

Mouse hit testing now uses the same visible item layout, while inline rendering and selection copy keep the full layout path for behavior parity.

Tests cover height cache reuse, visible-only item rendering, absolute selectable body coordinates, and output parity with the previous full-layout renderer.

Tested: env GOCACHE=/tmp/zero-go-cache go test ./internal/tui

Anandan 724167e90e Harden TUI layout and mouse routing (#226)
* Centralize TUI frame layout

Add a reusable transcript frame snapshot with terminal regions for header, body, footer, composer, and status lines. Mouse composer hit testing, overlay positioning, and transcript viewport mapping now consume the same frame geometry instead of recalculating pinned-header and clipped-footer offsets separately.

Tested: env GOCACHE=/tmp/zero-go-cache go test ./internal/tui

* Route TUI mouse hits through local regions

Return overlay hit coordinates relative to the overlay block and derive transcript hit rows from the shared body rect. This keeps the current scroll behavior while making mouse handling consume component-local geometry from the frame layout.

Tested: env GOCACHE=/tmp/zero-go-cache go test ./internal/tui

* Cover TUI frame geometry

Add focused tests for the shared frame snapshot: pinned header/body/footer regions, tiny-terminal footer clipping, composer mouse hit regions, overlay centering, and transcript mouse row mapping through the body region.

Tested: env GOCACHE=/tmp/zero-go-cache go test ./internal/tui

* Extract transcript viewport line window

Introduce a line-based transcript viewport adapter that preserves Zero's existing bottom-anchored scroll offset. Render slicing, chat scroll metrics, scrollChat, and transcript selection viewport mapping now share the same clamping and visible-window calculation.

Tested: env GOCACHE=/tmp/zero-go-cache go test ./internal/tui

* Build transcript body from layout items

Introduce a compatibility transcript body item layer for title, empty state, separators, transcript rows, pending prompts, streaming interim content, and spec review prompts. The body still renders to the same line/selectable output, but layout now records item spans and local selectable offsets for the next visible-range step.

Tested: env GOCACHE=/tmp/zero-go-cache go test ./internal/tui

Tested: /bin/bash -lc "GOCACHE=/tmp/zero-go-cache go test ./..."

* Address TUI layout review findings

Clamp overlay mouse hit regions to the visible transcript body and block transcript selection while the MCP add wizard is open. Strengthen layout and viewport edge-case tests, including full composer containment and degenerate dimensions.

Tested: env GOCACHE=/tmp/zero-go-cache go test ./internal/tui

Tested: /bin/bash -lc "GOCACHE=/tmp/zero-go-cache go test ./..."

* Make MCP wizard overlay test hit transcript text

CodeRabbit caught that the MCP add wizard blocking test clicked at x=0, which could miss selectable transcript text and pass without proving the overlay guard. This updates the test helper to return both textStart and y, then clicks that known selectable point before asserting the wizard blocks transcript selection behind the modal.

Tested: env GOCACHE=/tmp/zero-go-cache go test ./internal/tui

Tested: git diff --check

Tested: GOCACHE=/tmp/zero-go-cache go test ./...

* Route transcript windows through body layout

Thread the structured transcriptBodyLayout through alt-screen rendering, scroll metrics, and transcript mouse lookup instead of repeatedly joining and splitting the rendered body string. This preserves the current line-based viewport behavior while making the body layout the source of truth for visible windows and selectable line lookup.

This is an incremental step toward visible-item rendering and item-level caching; it does not change the transcript visual output or input flow.

Tested: env GOCACHE=/tmp/zero-go-cache go test ./internal/tui

Tested: git diff --check

Tested: /bin/bash -lc "GOCACHE=/tmp/zero-go-cache go test ./..."

* Reuse row cache for selectable transcript rows

Selectable user and assistant rows need selectable metadata for mouse interactions, but when no transcript selection is active their rendered strings are identical to the normal row render path. Route those rendered strings through renderRow so stable rows reuse the existing row cache while selection-active frames still render highlight-aware output.

This keeps transcript behavior unchanged and adds a regression test that verifies selectable assistant rows produce stable metadata while hitting the render cache on the second render.

Vasanth TandClaude 6092303e73 feat(tui): rotating "working word" for the liveness spinner (#221)
* feat(tui): rotating "working word" for the liveness spinner

The assistant interim block used to show a static "working…" placeholder
while the model was generating. That felt dead on long runs. Replace it
with a rotating gerund tuned for the Gitlawb / Zero brand: project-name
verbs (gitlawbmaxxing, zeroling, …) weighted 1.5x so the brand word
anchors the rotation, plus feature-as-verbs, gen-Z crowd-pleasers, and
a few Claude-Code originals for variety.

The rotation is a tiny ring buffer (working_words.go) advanced on each
spinner.Tick so the verb and the glyph stay in lockstep. Brand words
are duplicated in the ring, not randomized, so the cadence is
deterministic and the first frame is always "gitlawbmaxxing" — easy
to test, easy to reason about, and the first thing a long-running user
sees is the project name. Reset() rewinds the ring when a new run
starts (model.go: submit, spec_mode.go: spec approval → impl).

Lowercase throughout to brand-differentiate from Claude Code's Title
Case defaults. No config wiring (hardcoded list); can be a follow-up
if users ask for customisation.

Tests: 7 new tests in working_words_test.go (first frame, tick,
wrap, reset, brand weighting, base-list integrity, nil safety) plus
the existing interim-block test updated to assert "gitlawbmaxxing"
as the new default. Full internal/tui/ suite green in 2.7s.

* Address review feedback on working-words PR

Three review threads to close out:

**Cadence (~12 words/sec → ~1/sec)**
@anandh8x and @gnanam1990 both flagged the on-every-tick advance as
flicker. The spinner glyph should still spin fast (it conveys liveness),
but the word needs to be readable. Solution: the model owns a
`workingVerbTicks` counter and gates the advance at
`WorkingWordsStepEvery = 12` spinner ticks (~960ms at 80ms cadence).
The `workingWords` ring stays a dumb "advance one slot" type so unit
tests can tick it rapidly without waiting for a real spinner. New test
`TestWorkingVerbAdvancesOnStepEverySpinnerTicks` locks the cadence
behaviour in.

**Brand-name "inconsistency" (intentional)**
@gnanam1990 noted the code says "Gitlawb / OpenFable" while the repo,
binary, and PR description say "Zero". Author's call: the working-words
PR ships the rebrand-ahead-of-the-rebrand verbs on purpose. Kept the
existing strings (`gitlawbmaxxing`, `openfablemaxxing`, …) and tidied
the comments so the trade-off is explicit ("a planned rename; the
spinner brand is intentionally ahead of the rest of the project").
Also fixed a stale `model.go` comment that still said "zeroling"
(superseded by `openfablemaxxing` in the previous force-push).

**Taste call (pilled / aura-farming / maxxing)**
Both reviewers flagged these as user-facing with no config escape.
Author's call: ship as-is, with a comment on `vibeVerbs` calling out
the trade-off explicitly so the next reader can see it was a
deliberate decision rather than an oversight.

**weightedRing comment vs implementation**
CodeRabbit and @gnanam1990 both caught that the comment claimed brand
verbs are "interleaved" but the implementation appends them as a
sequential block at the end of the ring. Fixed the comment to match
the implementation and added a note on how to implement true
interleaving if it's ever wanted.

**CodeRabbit nits**
- `Reset()` now also checks `len(w.weighted) == 0` for consistency
  with `Tick()` and `Current()`.
- `weightedRing` body simplified to `append(ring, brandVerbs...)`
  instead of the conditional loop (same result, clearer intent).

**Competitor naming in comments**
@gnanam1990 asked to trim the few "Claude Code" mentions in package
comments. Replaced the explicit "Claude Code" references with neutral
phrasing ("upstream Claude-Code-compatible spinners", "a few classic
gerunds") that keeps the design rationale without naming the
competitor. The user-facing verb list is untouched.

Rebased onto current main (1e25fde) and resolved the spec_mode.go
merge conflict by keeping both the fade-seed and the working-verb
reset on the spec-impl path.

Build + vet + gofmt clean. Full internal/tui/ test suite green except
for the pre-existing env-fragile `TestModelCommandPersistsSelectedModelToUserConfig`
from PR #220 (fails here only because of local env, not this PR).

* Fix cadence test post-advance window (CodeRabbit)

The final block of `TestWorkingVerbAdvancesOnStepEverySpinnerTicks`
had two issues caught by CodeRabbit:

1. A `_ = m` no-op statement that asserted nothing.
2. A tautological check — it compared the post-advance verb against
   the *original* `before` value, which is always going to differ
   after the previous block already advanced.

The real intent was to verify that the cadence counter *resets* after
each advance (rather than carrying over), so a follow-up advance
lands one full `WorkingWordsStepEvery` window later — not one window
early due to a missed reset.

Rewrote the trailing block to:
- Capture the post-advance value explicitly (`afterAdvance`).
- Drive another (WorkingWordsStepEvery - 1) ticks after the advance.
- Assert the verb stayed at `afterAdvance` — catching the "counter
  doesn't reset" regression the original test was meant to guard
  against.

This now meaningfully tests three regressions:
- Gate removed (verb advances every tick) — caught by the first block.
- Gate set to 1 (same effect) — caught by the first block.
- Counter doesn't reset after advance (verb advances too eagerly) —
  caught by the new third block.

Updated the test docstring to call out all three failure modes.

Vasanth TandClaude 1e25fde3b1 feat(tui): age-based fade for streaming assistant text (#223)
* feat(tui): age-based fade for streaming assistant text

While the assistant reply streams in, the latest line appears in the
brand lime (\#caff3f) and gradually settles to the standard off-white
ink over ~1.2 seconds, line by line. The effect mirrors the lime
spinner glyph in the liveness block: a quiet visual signal that the
model is still emitting, not a stylized neon glow.

Design choices (per line, not per rune):
  * 12-step palette interpolated in linear sRGB from colorAccent to
    colorInk, pre-computed at init() so per-frame lookups are a
    struct-field access, not a hex parse.
  * 1.2s fade duration; 150ms tick (independent of the 80ms spinner).
  * Hard stop at stream end: the agentResponseMsg handler flips
    fadeActive = false and the next streamingFadeTickMsg short-circuits.
  * Reset on terminal resize (visual line count changes) and on cancel.
  * The last visual line uses lastStreamActivity (always freshest) so
    the user can see exactly where the model is currently typing.

Test fixtures that pre-populate m.streamingText without going through
the agentTextMsg branch keep rendering identically to before — the
fade code is defensive when lineAges is nil.

The spec-impl run (which calls runAgent directly, bypassing the
normal launchPrompt path) seeds the fade state explicitly so its
streaming text fades the same way regular runs do.

* fix(tui): address CodeRabbit review on streaming-fade PR

Four findings from CodeRabbit's review of #223, applied:

1. model.go agentTextMsg: schedule streamingFadeTick only on the
   inactive->active transition instead of on every delta. The tick
   is self-perpetuating (the streamingFadeTickMsg case schedules the
   next one), so re-scheduling on every incoming delta is redundant
   and would create multiple concurrent tick chains during long
   streams.

2. model.go agentResponseMsg: call m.resetStreamingFade() instead of
   setting only fadeActive = false. Leaving lineAges and
   lastStreamActivity populated allowed stale age data to carry over
   to the next turn and made lineAges grow indefinitely across many
   runs.

3. streaming_fade.go streamingLineBornAt: when the visual index is
   beyond the lineAges slice (a wrapped middle line), clamp to the
   last known logical age instead of returning time.Time{}. Wrapped
   continuation lines now keep fading in step with their siblings
   instead of snapping to base ink mid-paragraph.

4. streaming_fade_test.go TestStreamingFadePaletteHandlesBadHex:
   assert that every bucket's foreground is the unparseable base
   string instead of asserting on len(palette), which is a constant
   for a fixed-size array (the original assertion passed regardless
   of behavior and triggered SA4006). Also split the
   OutOfRangeReturnsZero test into ClampsToLast (for the new clamp
   behavior) and EmptyLineAgesReturnsZero (for the truly-empty case
   that should still return zero).

KRATOS a0b9876b69 OAuth / account login for providers (OpenRouter, xAI) + subscription-proxy support (#217)
* providers: authenticate model calls with an OAuth login when present

Foundation for account/subscription login: when a user is logged in via
`zero auth login <name>`, the OpenAI and Anthropic providers now authenticate
model requests with that OAuth bearer token, falling back to the API key when
there is no login. Auto-select, per the agreed design — no config needed.

  - providerio.SendWithAuthRetry: issues a request with an OAuth bearer (from a
    TokenResolver) or the API key, and retries ONCE with a force-refreshed token
    after a 401. A 401 means the server rejected the request without processing a
    completion, so replay-after-refresh is safe — the same no-duplicate-work basis
    SendWithRetry uses for 429/503. Never sends API key and bearer together.
  - openai + anthropic providers take an optional OAuthResolver and use
    SendWithAuthRetry. When OAuth is active the credential goes on Authorization
    (so Anthropic's x-api-key is correctly omitted). Gemini is unchanged.
  - providers.New threads Options.OAuthResolver to those two providers.
  - cli.oauthResolverForProfile builds the resolver from the unified oauth store:
    it attaches a resolver ONLY when a login already exists for the provider
    name, so API-key users incur no per-request store lookups. The resolver uses
    Manager.GetFresh (refresh near expiry) and Manager.Handle401 (force refresh on
    the 401 retry).
  - oauth: added ErrNoToken sentinel so "not logged in" is distinguishable from a
    real refresh failure (login removed mid-session → clean API-key fallback).

Tests (httptest): API-key fallback (nil resolver / ok=false), bearer wins +
never-both, 401→force-refresh→retry, stops after one retry, resolver error
surfaced. Local run check (real binary + mock OAuth + mock OpenAI-compatible LLM
requiring the bearer): with a login, `zero exec` sends Bearer <oauth-token> and
gets a completion; without a login it falls back to the (wrong) API key and the
mock returns 401 — proving the OAuth path.

Gates: gofmt/vet/build(host+linux+windows)/test -race/staticcheck(no new)/
govulncheck(0)/deadcode(no new) all pass.

* providers: add ChatGPT-subscription-via-proxy preset + OAuth/subscriptions docs

Follows verified research (cross-checked across ~30 sources) into using ChatGPT
and Claude subscriptions: a subscription OAuth token does NOT work as a standard
bearer on the public APIs. OpenAI's token only works against the Cloudflare-gated
ChatGPT backend (headless clients get cf-mitigated 403); Anthropic rejects
third-party subscription OAuth, requires Claude-Code identity spoofing, 400s on
tool calls (Max overage lane), and is contractually banned with active
enforcement. So zero does NOT call those backends or spoof those clients.

Instead, the supported pattern is a local proxy that holds the subscription
session and exposes a clean OpenAI/Anthropic-compatible endpoint on 127.0.0.1;
zero points at it (it already supports custom base URLs, and C1 supplies OAuth
bearer for gateways that issue standard tokens).

  - providercatalog: add `chatgpt-proxy` ("ChatGPT (local OAuth proxy)") — an
    OpenAI-compatible, local, no-API-key preset defaulting to the established
    proxy port (http://localhost:10531/v1), base URL overridable. Claude uses the
    existing `custom-anthropic-compatible` entry (no canonical Claude-proxy port
    to hardcode — not invented).
  - docs/oauth-subscriptions.md: full recipe — built-in OAuth login (C1), the
    verified reason subscriptions need a proxy, copy-paste config for ChatGPT and
    Claude via a local proxy, and the sanctioned alternatives (API key; spawning
    the real `claude` CLI for Anthropic subscription automation).

Local run check: a config using `catalogID: chatgpt-proxy` (base URL pointed at a
mock OpenAI-compatible proxy) routes `zero exec` through the proxy with no auth
header and returns a completion.

Gates: gofmt/vet/build(host+linux+windows)/test/staticcheck(clean)/govulncheck(0)/
deadcode(no new) all pass. No new module deps.

* provideroauth: OpenRouter browser PKCE login (mints an API key) + `zero auth openrouter`

Adds the cleanest real OAuth login surfaced by the provider survey: OpenRouter's
loopback PKCE flow. It needs no client_id (public), uses S256, and the exchange
mints a normal OpenRouter API key — so no token-spoofing or vendor-backend gating
is involved (unlike ChatGPT/Claude subscriptions).

  - internal/provideroauth.OpenRouterLogin: binds a 127.0.0.1 loopback, opens/prints
    https://openrouter.ai/auth?callback_url=…&code_challenge=…&code_challenge_method=S256,
    captures the code, and POSTs it + the PKCE verifier to
    /api/v1/auth/keys → {key}. PKCE binds the code, so no separate CSRF state is
    needed. Injectable base URL / HTTP client / browser-opener for tests.
  - cli: `zero auth openrouter` runs the flow and prints the minted key with usage
    guidance. ZERO_OPENROUTER_BASE_URL overrides the endpoint (self-hosted/tests).

Tests: full flow over httptest (mint, missing-code, non-2xx exchange, empty key,
browser-error). Local run check via the real binary against a mock: the command
emits the correct PKCE authorize URL, the loopback callback is captured, and the
key is minted end-to-end.

First of the in-wizard OAuth providers; the wizard "Log in with OAuth" option
(next commit) calls this same flow and saves the key to the profile.

Gates: gofmt/vet/build(host+linux+windows)/test -race/staticcheck(no new)/
govulncheck(0)/deadcode(no new) all pass. No new module deps.

* oauth: built-in provider presets + xAI (Grok) preset

Adds an overridable preset layer to the env-driven OAuth registry so well-known
providers work without per-field env configuration. ResolveConfig now seeds each
field from a baked-in preset and lets the matching ZERO_OAUTH_<NAME>_* env var
override it (env wins); flow falls back to the preset then loopback.

First preset: xAI (Grok) — standard OIDC, PUBLIC client (no secret), loopback +
device. The access token is accepted directly as a bearer on api.x.ai/v1 (an
OpenAI-compatible endpoint), so the existing C1 wiring uses it for an xai provider
profile — no header/identity spoofing. `zero auth login xai` now works out of the
box. CAVEATS (documented in code + help): the client_id is a public Grok-CLI
client not formally documented by xAI (may change; override via env), and use
requires a SuperGrok / X Premium+ subscription.

Tests: preset resolution, env-overrides-preset (per field + flow), and that a
provider with neither preset nor env still errors. Local run check: `zero auth
login xai --device` (endpoints pointed at a mock, client_id NOT overridden) logs
in and the mock confirms the preset client_id b1a00492-… was sent.

Gates: gofmt/vet/build(host+linux+windows)/test/staticcheck(no new)/govulncheck(0)/
deadcode(no new) all pass. No new module deps.

* tui: in-wizard "Log in with OAuth" option (OpenRouter) + browser opener

Adds the credential-step OAuth login the setup wizard was missing. For a provider
that supports a usable browser OAuth flow (currently OpenRouter), the credential
screen now offers "ctrl+o to log in with OAuth in the browser (no key needed)"
alongside pasting a key.

Flow: ctrl+o → the wizard marks itself oauthPending and dispatches an async
tea.Cmd that runs provideroauth.OpenRouterLogin (opens the browser via the new
internal/browser opener, captures the loopback callback, mints a key). While it
runs the step shows "Opening your browser… (or run: zero auth openrouter)";
Esc cancels. On success the minted key fills the credential and the wizard
advances to model selection; on failure the redacted error is shown and the user
can retry or paste a key.

  - internal/browser: cross-platform OpenURL (open / xdg-open / rundll32) with a
    pure, unit-tested per-OS command builder.
  - provider_wizard: oauthPending/oauthErr state, providerWizardSupportsOAuth
    (OpenRouter only — ChatGPT/Claude use the proxy preset, others paste a key),
    the async cmd + result msg, and credential-step render/keys.
  - model.Update routes the OAuth result message.

Tests: openCommand per-OS; supportsOAuth (openrouter yes / openai no); ctrl+o
starts OAuth for OpenRouter and is a no-op otherwise; apply-success advances +
applies the key; apply-error stays + surfaces the message; render shows the hint
and the pending state. The interactive browser flow itself is the same one C3
verified end-to-end against a mock.

Gates: gofmt/vet/build(host+linux+windows)/test -race/staticcheck(no new — the
SA1019 mouse nits are pre-existing on origin/main)/govulncheck(0)/deadcode(no new).
No new module deps.

* docs: cover the built-in OpenRouter + xAI OAuth logins

Document the two turnkey OAuth providers added in this branch (OpenRouter browser
key-mint via `zero auth openrouter` / wizard ctrl+o; xAI via `zero auth login
xai`), alongside the existing subscription-proxy and custom-provider guidance.

* tui: method-first provider setup — a prominent "Sign in with OAuth" path

Reworks `/provider` setup to lead with a connect-method chooser, modeled on Codex
/ Claude Code / gemini-cli (verified via a UX survey), so OAuth is a first-class,
separate option instead of a key buried at the credential step.

New first step "How do you want to connect?":
  ❯ Sign in with OAuth                    (default when any OAuth provider exists)
      One-click browser login, no API key to copy (OpenRouter, xAI).
    Paste an API key / browse providers
      Any of 20+ providers, a local model, or a subscription via proxy.

  - OAuth path → a dedicated list of ONLY OAuth-capable providers
    (providercatalog.OAuthProviders()), each with a mode badge; selecting one
    runs the browser login (OpenRouter mints a key; xAI/preset providers store a
    refreshable token via the engine) and jumps straight to model selection,
    skipping the key/endpoint steps. A waiting screen shows progress + a CLI
    fallback; Esc cancels; errors are redacted and retryable.
  - Browse path → the existing full catalog → key/endpoint/model, unchanged.
  - ChatGPT/Claude are NOT offered as in-app OAuth (they can't work) — they remain
    reachable as the proxy/custom providers under "browse".

  - providercatalog: Descriptor gains OAuth/OAuthMintsKey/OAuthDeviceFlow; openrouter
    + xai are flagged; OAuthProviders() is the single source of truth.
  - wizard: new method step + OAuth provider list + per-provider OAuth dispatch
    (reuses provideroauth.OpenRouterLogin and the oauth engine login), waiting/
    render/keys/step-line/retreat all updated; mouse + keys ignored while a login
    is in flight.

Tests: catalog OAuth flags + OAuthProviders(); method chooser OAuth vs browse
paths; OAuth dispatch from the list; retreat→method; render shows the chooser +
provider list; existing wizard tests updated for the new first step. All tui tests
pass under -race.

Gates: gofmt/vet/build(host+linux+windows)/test/staticcheck(no new)/govulncheck(0)/
deadcode(no new) all pass. No new module deps.

* docs: document the /provider "Sign in with OAuth" method chooser

* tui: mirror the "Sign in with OAuth" method chooser in first-run onboarding

First-run setup (onboarding.go) was a separate flow that still showed its bare
provider list. Add the same connect-method chooser so new users get the prominent
OAuth path too, keeping /provider and first-run as one mental model.

  - New setupStageMethod (after Welcome): "How do you want to connect?" with
    "Sign in with OAuth" (default) and "Paste an API key / browse providers".
  - OAuth path filters the provider list to OAuth-capable providers, runs the same
    browser login (OpenRouter mints a key → captured as the setup credential; xAI
    stores a refreshable token and the profile is named after the provider so the
    runtime resolver attaches the bearer), shows a waiting screen, then jumps to
    model selection (skipping endpoint/name/credentials). Esc cancels; errors are
    redacted.
  - Browse path is the existing flow, unchanged. setupStages()/navigation/back/
    progress/footer/mouse all updated; OAuth result routed via model.Update.

Tests: method chooser OAuth path (OAuth-only list + retreat clears it) and
apply-OAuth-success advances to model with the minted key; existing onboarding
tests updated for the new step (pressSetupContinue transparently skips it). All
tui tests pass under -race.

Gates: gofmt/vet/build(host+linux+windows)/test/staticcheck(no new)/govulncheck(0)/
deadcode(no new) all pass. No new module deps.

* catalog+tui: show ChatGPT/Claude in the OAuth chooser as local-proxy entries

The "Sign in with OAuth" chooser listed only the real-OAuth providers (OpenRouter,
xAI), so ChatGPT and Claude looked missing. They can't do real in-app OAuth — a
subscription token is Cloudflare-gated (ChatGPT) / ToS-restricted for third-party
use (Claude) — so instead of hiding them or faking a login, list them honestly as
"subscription · needs a local proxy" entries that route into proxy setup.

  - catalog: new Descriptor.OAuthProxy flag + OAuthProxyProviders(); mark
    chatgpt-proxy and a new claude-proxy (local Anthropic-compatible, keyless)
    entry. localAnthropic() helper. Proxy entries are not OAuth (no fake login).
  - wizard + onboarding: the OAuth list now appends the proxy entries after the
    real OAuth providers (catalog order keeps real ones first). Selecting a proxy
    entry leaves OAuth mode and drops into the normal browse flow with the proxy
    provider selected and its default URL/model pre-filled, so the user just
    points Zero at the local proxy they run. No browser login is launched.
  - providerWizardNeedsEndpoint now true for proxy entries (the local port
    varies); faint badge "subscription · needs a local proxy".
  - docs/oauth-subscriptions.md: chooser now shows the four entries and explains
    the proxy routing.

Tests: catalog classification (OAuthProviders vs OAuthProxyProviders, flags);
wizard + onboarding proxy-entry routing (leaves OAuth mode, starts no login,
lands on endpoint with the URL pre-filled). Full suite green under -race;
staticcheck/govulncheck/deadcode clean. No new deps.

* oauth+tui: add xAI device-code (RFC 8628) login to the OAuth chooser

The OAuth chooser only did browser/loopback login, which can't work on a headless
or SSH box (no browser to open). Add device-code as a first-class option for
providers that support it (xAI).

  - oauth.Manager: PrepareDeviceLogin (request code) + CompleteDeviceLogin (poll +
    store), splitting the monolithic device flow so the UI can display the
    user_code + verification URI while it waits. CLI Login(Device:true) unchanged.
  - tui (shared oauth_device.go): oauthPreferDeviceFlow() picks device by default
    on SSH / headless Linux (no DISPLAY) or when ZERO_OAUTH_DEVICE is set;
    oauthDevicePrepare/Complete drive the two phases off the UI goroutine.
  - /provider wizard + first-run onboarding: device-capable providers show
    "Enter sign in · d device code" — Enter uses the browser (or device if
    headless), "d" forces device. The waiting screen shows the code + URL to
    enter elsewhere, then polls; success advances to model selection. Esc cancels;
    errors are redacted; device state is cleared on success/cancel/back.
  - docs: document the device-code path and ZERO_OAUTH_DEVICE.

Tests: manager Prepare/Complete two-phase; wizard + onboarding 'd' shortcut,
device-code display + poll dispatch, error surfacing, and success clearing device
state. Full suite green under -race; staticcheck/govulncheck/deadcode clean. No
new deps.

* tui: authenticate model discovery with the OAuth token so the live list shows

After an xAI sign-in the bearer lives in the token store, not as a pasted key, so
the post-login model step ran /models with no credential → it always fell back to
the curated list (with a discovery error). Now the user picks from the real live
model list after OAuth, like other CLIs.

  - oauthStoredToken() resolves a fresh stored token for a token-login provider.
  - wizard + onboarding discovery resolve and inject that token into the discovery
    profile inside the async goroutine (token refresh is network I/O); OpenRouter
    still uses its minted key, API-key users are unchanged. Discovery timeout
    bumped 8s→12s to cover an on-demand refresh.
  - The resolved token is added to the redaction secret set so it can never leak
    into a surfaced discovery error. If discovery still fails (offline), the
    curated per-provider fallback list is shown as before — the user always gets a
    pickable list.

Tests: oauthStoredToken reads a seeded login / returns empty when absent;
wizard discovery injects the stored token into the /models profile. Hermetic via
ZERO_OAUTH_TOKENS_PATH. Full suite green under -race; staticcheck/govulncheck/
deadcode clean. No new deps.

* catalog+tui: drop ChatGPT/Claude from the OAuth chooser — OpenRouter + xAI only

Reverts the proxy-entry listing: the "Sign in with OAuth" chooser now shows only
the providers that do real OAuth (OpenRouter, xAI). ChatGPT/Claude looked
confusing there since they can't actually sign in — they remain reachable via
"Paste an API key / browse providers" + the local-proxy recipe in
docs/oauth-subscriptions.md.

  - catalog: remove the Descriptor.OAuthProxy flag, OAuthProxyProviders(), the
    oauthProxyProvider/localAnthropic helpers, and the claude-proxy entry.
    chatgpt-proxy stays as a plain browse/config entry (its pre-existing role).
  - wizard + onboarding: OAuth list = OAuthProviders() again; removed the
    proxy→browse routing, the OAuthProxy badge, and the OAuthProxy endpoint rule.
  - device-code + OAuth-token model discovery (the later features) are untouched.
  - docs + tests updated to the two-entry chooser.

Gates: gofmt/vet/build(host+linux+windows)/test -race/staticcheck/deadcode all
clean. No new deps.

* cli: recognize a stored OAuth login as a provider credential

A provider authenticated via OAuth (e.g. `zero auth login xai`) has no inline
key or env var, so setupRequired treated it as unconfigured and forced onboarding
on every launch — and the active provider could be passed over for a different
one. setupRequired now also counts a stored OAuth login (read from the token
store) as a credential, so an OAuth-logged-in provider stays usable without
onboarding.

Tests: providerHasOAuthLogin (by name/catalog id); setupRequired returns false
for an OAuth-logged-in provider, true for a keyless one with no login.

* Address review feedback on OAuth provider login

Resolve CodeRabbit review comments on this PR:

- PrepareDeviceLogin: self-bound the network prepare (endpoint discovery +
  device-code request) with opts.Timeout (default 5m) like Login, so a caller
  passing an unbounded context still gets the timeout guarantee.
- CompleteDeviceLogin: bound the poll by the device code's own ExpiresAt so an
  unbounded caller context cannot leave an in-flight request hanging past the
  code's lifetime (PollDeviceToken already re-checks between polls).
- OAuthProviders(): return cloned descriptors, matching All()/the other
  accessors, so callers can't mutate the shared catalog backing slices.
- Onboarding applySetupOAuth / applySetupOAuthDeviceCode: ignore a stale result
  for a provider the user has since switched away from, so a late login can't
  capture a credential against the wrong provider.
- Onboarding: surface a failed OAuth login on the provider list the user lands
  on (the waiting screen that owned the error is gone once oauthPending clears),
  so the failure isn't silent and the user can retry.
- Onboarding: hide the "Sign in with OAuth" method when this setup's own
  provider list has no OAuth-capable entry, so it can't be selected into an
  empty provider list (setupMethodOptions).
- docs/oauth-subscriptions.md: label the bare example fences (text) and update
  the Anthropic policy section for the April 4 2026 third-party cutoff.

Adds tests for the descriptor-clone isolation and the method-option filtering.

* oauth: gate built-in presets behind ZERO_OAUTH_ALLOW_PRESETS

The xAI preset baked a third-party OAuth client_id into the default
credential path, which breaks the engine's documented invariant that no
third-party OAuth client identity is used unless the operator configures
it. Rather than drop the convenience entirely, make presets opt-in:

- ResolveConfig only consults builtinOAuthPresets when ZERO_OAUTH_ALLOW_PRESETS
  is truthy (presetsAllowed); by default every field must come from
  ZERO_OAUTH_<NAME>_* env, so the binary's preset client_id is never used
  without an explicit opt-in.
- The "not configured" error now points the user at ZERO_OAUTH_ALLOW_PRESETS
  when a preset exists, so the wizard/CLI failure is self-documenting.
- Refresh the package, Registry, and preset docs to describe the opt-in;
  env still overrides any preset field.
- docs/oauth-subscriptions.md: document the flag for one-click xAI sign-in.

Keeps both: invariant-clean by default, one-click xAI for opted-in users.
Tests: preset resolution now requires the opt-in; added a gate-off test
asserting xAI stays inert (and the error names the flag) without it.

* oauth: read a stored token without resolving provider config

GetFresh resolved the provider OAuth config for every read via loadForKey,
even when the stored token was still valid and no refresh would happen.
With presets gated behind ZERO_OAUTH_ALLOW_PRESETS, that made a stored xAI
login unreadable (and stalled the proactive refresh scheduler) unless the
opt-in flag was set at read time — config that is only needed to refresh.

Split loadForKey into loadToken (token only) and resolveConfigForKey
(refresh-only). GetFresh now returns a still-valid token without touching
the config; only an actual refresh (or Handle401) resolves endpoints +
client. The scheduler's load uses loadToken too, so proactive refresh
survives a gated preset and only the refresh attempt needs the config.

Fixes the Smoke failures TestOAuthStoredTokenReadsStoredLogin and
TestProviderWizardDiscoveryUsesOAuthToken (a fresh stored token must be
readable without the preset opt-in).

* Address CodeRabbit re-review round 2 on OAuth provider login

- providerio SendWithAuthRetry: resolve the auth headers BEFORE dispatching, so
  a resolver error returns immediately instead of letting SendWithRetry send an
  unauthenticated request (leaking the path/body).
- tui handleMouse: ignore all mouse input (clicks + wheel) while a provider-wizard
  OAuth login is pending, so a stray scroll can't change the selected provider
  mid-login (mirrors the keyboard pending guard; the setup mouse handler already
  did this).
- cli runAuthOpenRouter: reject unexpected args/flags (e.g. --json) instead of
  silently running the login, matching the other auth subcommands.
- cli auth help: align the preset wording with the opt-in gate — openrouter works
  out of the box; xai needs ZERO_OAUTH_ALLOW_PRESETS=1 or ZERO_OAUTH_XAI_*.
- onboarding_test: compute selectedMethod from m.setupMethodOptions() (the
  setup-filtered list) instead of providerWizardMethodOptions(), which could index
  past the end when OAuth is hidden.
- docs/oauth-subscriptions.md: sharpen the Anthropic timeline — Feb 19 2026 docs
  update, then the April 4 2026 enforcement that stopped subscription OAuth tokens
  working in third-party harnesses; current path is an API key or pay-as-you-go.

Adds tests for the no-dispatch-on-resolver-error path and openrouter arg rejection.

* Address CodeRabbit re-review round 3 on OAuth provider login

Two findings missed in the previous round:

- oauth manager resolveConfigForKey: resolve issuer metadata before refreshing.
  It returned ResolveConfig's result without calling resolveEndpoints, so a
  provider configured with only ZERO_OAUTH_<NAME>_ISSUER_URL (no TOKEN_URL) had
  an empty token endpoint and could not refresh on GetFresh/Handle401. Thread the
  context through and run discovery; adds a test that an issuer-only provider
  refreshes via the discovered token endpoint.
- provider_wizard_oauth_test: assert openrouter is actually present in the OAuth
  list before selecting it, so the test can't silently pass against a different
  provider if openrouter is renamed/removed.

(The re-flagged PrepareDeviceLogin timeout is already handled — it self-bounds
with opts.Timeout, same as Login.)

* Address CodeRabbit re-review round 4 (nitpicks) on OAuth provider login

- presets scopesOrPreset: return a copy of the preset scopes so a caller
  appending to cfg.Scopes can't mutate the shared global preset slice.
- provideroauth/openrouter: use bytes.NewReader(payload) instead of
  strings.NewReader(string(payload)) (avoid a needless []byte->string copy).
- onboarding setupCredentialSummary: show "OAuth token" on the Ready screen for
  an OAuth token-login provider (e.g. xAI) instead of "env var XAI_API_KEY" — it
  is authenticated by a stored token, not a key. Key-minting OAuth (OpenRouter)
  still resolves to a saved key.

(The flagged "Registry doc says no built-ins" was already corrected in the
preset opt-in commit — the doc now describes the ZERO_OAUTH_ALLOW_PRESETS gate.)

Adds tests for the scope-slice copy and the OAuth-token credential summary.

KRATOS c38444157c Audit backlog: tui mouse API, notify webhook, swarm scheduling, daemon-remote bundles, MCP/oauth store unification, OS keyring, dead-code prune (#216)
* tui: migrate off the deprecated Bubble Tea mouse Type API (SA1019)

The mouse classification helpers checked both the current Button/Action pair and
the deprecated msg.Type / tea.Mouse* constants. Bubble Tea's parser always
populates Button+Action and only DERIVES Type from them, so the Type fallbacks
were pure redundancy (a left-button drag is Action==Motion, already covered by
mouseMotion). Drop them — clears all 11 SA1019 findings in internal/tui with no
behavior change. The left-drag test now asserts the Action==Motion path directly.

Gates: gofmt/vet/build(host+linux+windows)/test -race/staticcheck(SA1019 0)/
deadcode(no new) all pass.

* notify: wire the webhook sink behind an opt-in env var

The WebhookSink (Slack / generic JSON POST on turn completion) was fully
implemented, redaction-safe, and tested — but never attached to a Notifier, so
deadcode flagged its entire machinery (NewWebhookSink, Emit, text, redactLinks,
log, eventType, readSnippet) as unreachable.

Wire it via a small, testable helper, MaybeAddWebhookSink(n, env, logf):
  - reads ZERO_NOTIFY_WEBHOOK_URL (+ optional ZERO_NOTIFY_WEBHOOK_SUMMARY)
  - no-op when the URL is unset/blank, so it is safe to call unconditionally
  - sourcing the URL from the environment keeps the secret token out of any
    on-disk config file

Attached at both notifier construction sites:
  - headless exec: failed deliveries log to stderr (never stdout); the sink
    redacts before logging
  - TUI: logf=nil so a delivery failure can't corrupt the alt-screen

The sink stays gated by the existing Mode/focus policy (verified by
TestNotifierOffSuppressesSinks), so a webhook only fires when notifications are
enabled (e.g. --notify both) — no change to default behavior. Opt-in and
fail-closed: with the env var unset nothing is attached.

deadcode: 100 -> 93 unreachable funcs (the 7 WebhookSink entries become
reachable); no new dead code. gofmt/vet/build(host+linux+windows)/test -race/
staticcheck(no new)/govulncheck(0) all pass.

* swarm: add opt-in recurring-spawn scheduler (wakeup + daily)

Adds a dependency-free Scheduler to internal/swarm so a member can be spawned on
a recurring schedule, plus a swarm_schedule tool to drive it.

  - Schedule is interval-based ("wakeup", every >= 1s) with an optional first
    delay and a MaxRuns cap; a daily "HH:MM" ("cron") time is expressed as a 24h
    interval whose first delay lands on the next occurrence.
  - Each fire spawns a fresh member through the existing Swarm.Spawn path, so
    members inherit the recorded policy and are bounded by the team slot cap +
    queue. Non-overlapping by default: a fire is skipped while the job's previous
    spawn is still running, preventing queue pile-up.
  - Scheduler is lazily created (Swarm.Scheduler()), opt-in (nothing runs until a
    job is added), and tied to the Swarm's base context — Swarm.Close() stops the
    scheduler first so no spawn fires during shutdown.
  - swarm_schedule tool: action add|list|cancel; prompt-gated like swarm_spawn;
    add validates schedule + agent type up front (fail fast).

The timing loop takes an injectable ticker, so the tests drive fires
deterministically with no real time (fire/skip/cap/cancel/close, plus pure
nextDailyDelay/parseClock/swarmInt). All swarm tests pass 3x under -race.

Gates: gofmt/vet/build(host+linux+windows)/test/staticcheck(clean)/govulncheck(0)/
deadcode(no new) all pass.

* daemon/remote: SessionLink + git-bundle upload over the bridge

Adds an opt-in way to ship a local repo's git history to a remote daemon and
link a remote working tree to it — without a shared filesystem or a network git
remote. The daemon core (protocol/server) is untouched; all changes live in the
remote package plus a CLI hook.

Wire:
  - The auth handshake gains an optional Mode field ("" / "session" => a daemon
    session as before; "bundle" => a one-shot git-bundle upload). Unknown modes,
    or bundle mode when uploads are disabled, are denied (fail closed).
  - Bundle transfer reuses the daemon frame codec: a header frame (link id +
    exact size), then the bundle bytes as KindData frames, then a result frame.

Server (Bridge):
  - BridgeOptions.BundleDir enables uploads (empty => refused). A received bundle
    is size-capped (default 256 MiB), staged to a temp file, `git bundle verify`-d,
    then `git clone`-d into a staging dir and atomically renamed over
    <BundleDir>/<link-id>. Link ids are sanitized to a single path component and
    containment is re-checked, so an upload can never escape the bundle dir.

Client:
  - UploadRepoBundle creates `git bundle create --all` of a work tree, hashes it
    (sha256), streams it over an authenticated bundle-mode TLS connection, and
    returns a SessionLink {address, link id, remote path, bundle sha}. SessionLink
    persists as a 0600 atomic JSON file (token never stored) with Save/Load/Validate.

CLI:
  - `daemon serve-remote --bundle-dir <d>` enables uploads.
  - `daemon link --remote <addr> --repo <dir> --id <name> [--out <file>]` uploads
    and prints the remote path (+ a ready run command); `daemon link --show <file>`
    prints a saved link.

Tests: git bundle create/verify/clone roundtrip; link-id sanitization + path
containment; SessionLink save/load/validate (0600); and a full bridge upload E2E
over real TLS (extract + content check + re-upload-replaces + disabled + bad
token). All remote tests pass 2x under -race; CLI smoke verified via the binary.

Gates: gofmt/vet/build(host+linux+windows)/test/staticcheck(no new)/
govulncheck(0)/deadcode(no new) all pass.

* mcp: unify OAuth token storage onto the shared oauth store

MCP server tokens lived in their own mcp-oauth-tokens.json with a bespoke
codec/lock, separate from the provider-login store (internal/oauth). The oauth
store already reserved the "mcp:" key namespace for exactly this. Unify them.

  - mcp.TokenStore now delegates to internal/oauth.Store, keying each server's
    token as "mcp:<server>". Its public API (StoredToken/TokenStatus/Save/Load/
    Delete/Status/FilePath) is unchanged, so callers (network client, CLI) are
    untouched. The bespoke read/write/lock code is removed in favor of the shared,
    cross-process-locked, atomic store.
  - Transparent, non-destructive migration on first construction: a legacy
    mcp-oauth-tokens.json is imported into the unified store (only entries not
    already present — a newer unified token is never overwritten), then renamed to
    a ".migrated" backup so it is imported at most once and stays recoverable.
    A missing / unreadable / unknown-schema legacy file is left untouched and
    never blocks startup. An explicit FilePath suppresses the default-path
    migration so tests/overrides can't touch the real user config.
  - Server names that can't form a valid namespaced key (oauth.ValidateKey) are
    rejected on save and skipped during migration. Added oauth.Store.FilePath().

The token format was already identical (access/refresh/type/scopes/expires), so
this is a key rename, not a format change. Existing TokenStore tests pass
unchanged (they exercise the API); added migration + namespacing + newer-wins
tests. Local run check: `zero mcp oauth status` migrates a seeded legacy file
into oauth-tokens.json under mcp:demo, renames the legacy to .migrated, and leaks
no token material.

Gates: gofmt/vet/build(host+linux+windows)/test -race/staticcheck(clean)/
govulncheck(0)/deadcode(no new) all pass.

* oauth: add an opt-in OS keyring storage backend

Introduces a pluggable storage backend for the unified oauth token store and a
dependency-free OS keyring implementation, selected with
ZERO_OAUTH_STORAGE=keyring (default stays the 0600 file).

  - internal/keyring: a small, third-party-dep-free secret store backed by the OS
    tooling — `security` on macOS, `secret-tool` (libsecret) on Linux; other
    platforms report unsupported. On Linux the secret is passed via stdin (never
    the argv); on macOS `security` takes it as an argument (briefly visible in the
    process list) — documented, and a reason to prefer the file backend there.
    A runner seam makes the per-OS command logic fully testable without a real
    keychain.
  - internal/oauth: Store now persists its JSON blob through a blobStore backend.
    fileBlob preserves the exact prior behavior (0600, atomic write, cross-process
    lock file). keyringBlob stores the blob as one base64 entry (keeps multi-line
    JSON a single control-char-free value) via a KeyringClient. NewStore resolves
    the backend from StoreOptions.Storage or ZERO_OAUTH_STORAGE; unknown storage
    and an unavailable keyring fail closed with a clear error.

Because both `zero auth` and the (now unified) MCP token store construct their
store through oauth.NewStore, the keyring backend is honored by both with no
call-site changes. Added oauth.Store.FilePath() returns a "keyring:" identifier
for that backend.

No new module dependency (go.mod unchanged). Tests: keyring round-trip/not-found/
unsupported/missing-binary/stdin-not-argv via an injected runner; store keyring
round-trip + base64-at-rest + storage selection; all existing file-backend tests
pass unchanged. Local run check (macOS): validated the exact `security`
add/find/delete shapes and the not-found exit code (44) against the real binary,
and `mcp oauth status` with ZERO_OAUTH_STORAGE=keyring reads the real keychain
cleanly.

Gates: gofmt/vet/build(host+linux+windows)/test -race/staticcheck(no new)/
govulncheck(0)/deadcode(no new) all pass.

* all: prune unused unexported functions (dead-code sweep)

Removes 15 unexported functions/types/consts that are unreachable even from
tests (every one flagged by staticcheck U1000), clearing the U1000 noise the v16
audit surfaced. Conservative by design: only unexported, test-unused symbols are
removed — exported internal API (which may be an intentional surface or used only
by tests) is deliberately left in place.

Removed:
  - agenteval: validateExpectedChangedFiles
  - providers/gemini: const providerName
  - tui: stripMarkdownInline, removeTrailingAtToken,
    noopModelSwitchCompactionPolicy (+ BeforeModelSwitch), deleteComposerLineBefore,
    deleteComposerLineAfter, deleteCompletedFileMentionBefore, mcpViewStatus,
    mcpServerLines, fitCommandOutput, (*commandPicker).clearQuery,
    tuiTheme.onPanel2, indentText

No behavior change (the symbols had no callers). staticcheck U1000 is now empty;
deadcode drops accordingly with no genuinely-new unreachable functions (verified
by a name-based diff vs origin/main). gofmt/vet/build(host+linux+windows)/full
test all pass.

* Address review feedback on the audit backlog

Resolve CodeRabbit review comments on this PR:

- keyring isNotFound: match the specific not-found exit codes (macOS `security`
  44 = errSecItemNotFound; `secret-tool` 1) instead of treating any non-zero
  exit as "no entry", so a real failure (locked keychain, permissions) surfaces
  instead of being masked as absent.
- swarm scheduler daily_at: recompute each fire as the next local HH:MM rather
  than adding a fixed 24h, so a wall-clock daily schedule does not drift across
  DST. Adds Daily/Hour/Minute to Schedule and a clock to the Scheduler.
- swarm scheduler: reject Add when the scheduler context is already canceled
  (not just when closed); re-check cancellation after a tick so a tick+cancel
  race can't spawn one extra member after Cancel/Close.
- swarm schedule_tool swarmInt: reject non-integer / non-finite JSON numbers
  (max_runs=1.9 errors instead of silently truncating to 1).
- mcp migrateLegacy: resolve a relative LegacyPath to absolute before the
  same-file guard so it can't be bypassed by a relative spelling.
- oauth keyring store: serialize the keyring read-modify-write with a
  cross-process lock file (best-effort, beside the config dir) so concurrent
  processes don't clobber each other's tokens; previously withLock was a no-op.

Adds tests for the non-not-found keyring error, the daily delay recompute, the
Add-after-cancel guard, and non-integer swarmInt.

* swarm: make nextDailyDelay roll the day, not add 24h (DST)

CodeRabbit follow-up: the run loop already recomputes a daily job's delay each
cycle, but nextDailyDelay itself rolled "passed today" to the next occurrence
with Add(24*time.Hour). On a DST changeover day (23h/25h) that fires an hour
early/late. Use time.Date(..., day+1, hour, minute, ...) so Go normalizes the
date and applies the correct local offset, holding the wall-clock HH:MM across
DST. Adds an America/New_York spring-forward test (skips if tzdata is absent).

KRATOS 75ecf8e385 oauth: opt-in AES-256-GCM encrypted-at-rest token storage (#213)
* oauth: opt-in AES-256-GCM encrypted-at-rest token storage

OAuth Phase 2: add an encrypted token-store backend. The default backend still
writes the 0600 plaintext JSON unchanged; setting ZERO_OAUTH_STORAGE=encrypted-file
encrypts the token file with AES-256-GCM under a per-user random 32-byte secret
persisted 0600 beside the token file (<tokens>.secret).

- internal/oauth/encrypt.go: aesGCMCrypter (nonce||ciphertext, GCM tamper
  detection) + load-or-create secret (atomic 0600 write). Pure stdlib, no dep.
- Store gains an optional crypter: readState decrypts before unmarshal, writeState
  encrypts after marshal. A missing secret, a short blob, or a failed auth tag all
  fail closed (no silent empty/plaintext fallback).
- CLI: newAuthManager selects the backend from ZERO_OAUTH_STORAGE; `zero auth`
  help documents it.

Tests: crypter round-trip + tamper, secret create/persist/0600/wrong-size,
store-through-encrypted (ciphertext on disk, round-trip, Status/Delete, tamper +
missing-secret fail-closed). Gates: gofmt/vet/build(host+linux+windows)/test
-race/staticcheck(no new)/govulncheck(0)/deadcode(no new) all pass. Local run
check: device login under ZERO_OAUTH_STORAGE=encrypted-file writes a ciphertext
file (no plaintext token), .secret is 0600, and `zero auth status` reads it back.

* Address review feedback on encrypted token storage

Resolve CodeRabbit review comments on this PR:

- newAuthManager: reject an unsupported ZERO_OAUTH_STORAGE value instead of
  silently downgrading to plaintext. A mistyped non-empty value now fails fast
  ("invalid ZERO_OAUTH_STORAGE ... (supported: encrypted-file)") so a user who
  believes encryption is on is never left writing plaintext.
- loadOrCreateSecret: fix the first-run TOCTOU race. os.Rename publishes by
  clobbering on POSIX, so two concurrent processes could each generate a secret
  and the loser would silently orphan every token it then encrypts. Create the
  secret exclusively (O_CREATE|O_EXCL); the loser adopts the winner's on-disk
  secret. Factored the read+size-validate into readSecretFile and dropped the
  now-unused clock plumbing from the crypter.
- encrypt_test: handle os.Stat / os.ReadFile errors before dereferencing the
  result (mode/index) so a real I/O failure surfaces instead of a panic.

Adds a test asserting an invalid ZERO_OAUTH_STORAGE fails fast.

* oauth: retry the secret read when losing the first-run create race

CodeRabbit follow-up: the O_EXCL create path read the on-disk secret
immediately after EEXIST, but the winner may not have finished writing it
yet, so a loser could observe a short file and fail transiently. Retry the
read briefly (bounded) so concurrent first-run invocations converge on the
winner's secret. Adds a -race concurrency test asserting convergence.

KRATOS efb6b79164 web_search robustness + chat UX: collapse, clipboard, scroll-pin, proactive search (#218)
* web_search: fix #209 follow-ups (tolerant score, render gate, redaction, FQDN)

Verified-and-fixed defects from a review of #209:
  - Tolerant score decode (lenientScore): a stringified/odd/null "score" no longer
    makes json.Unmarshal discard the entire response; it degrades to absent.
  - Score render gate rounds first (>= 0.01) so tiny positives and negatives no
    longer print a noisy "score 0.00".
  - Domain-filter error now goes through redactWebSearchText, matching the other
    error paths.
  - Trailing-dot FQDN symmetry: "react.dev." and "react.dev" normalize the same
    on both the allowlist and result sides.

Left as-is (intended, tested): scheme-less host:port allowlist entries. Includes
mixed-type domains-array tests.

* web_search: only register the built-in tool when a backend is configured

When no search backend is set (ZERO_WEBSEARCH_BASE_URL / ZERO_WEBSEARCH_BACKEND),
CoreNetworkTools no longer offers the built-in web_search. Previously it was always
registered, so a model with an MCP search tool (e.g. Exa) would burn several calls
+ high-risk permission prompts on the built-in tool — which can only return
"no backend configured" — before falling back to the working MCP tool.

Now: no backend -> only web_fetch (+ any MCP search tool) is offered, so the model
uses the MCP search directly. A configured backend behaves exactly as before.

Tests: registry/web_search/specialist tests that asserted web_search is always in
CoreTools now configure a backend; added a test that it is omitted when none is set.

(Pre-existing, unrelated: internal/cli doctor/exec tests fail in the sandbox on
origin/main too — network/provider-dependent, not touched here.)

* tui: copy selected transcript text to the native OS clipboard

Selecting transcript text auto-copies on mouse release, but the copy went only
through OSC52 (ansi.SetSystemClipboard), which macOS Terminal.app doesn't support
at all and iTerm2 / some Windows Terminal builds have off by default — so the
selection silently never reached the clipboard.

Copy via the native clipboard (pbcopy / clip.exe / xclip) first, which works on
local terminals regardless of OSC52, and fall back to OSC52 for remote/SSH
sessions where no local clipboard utility is reachable. atotto/clipboard was
already in the module graph (indirect); promoted to a direct import — no new
dependency.

Gates: gofmt/vet/build(host+linux+windows)/tui test -race/staticcheck all pass.

* tui: collapse long tool output by default with click-to-expand

Long, noisy tool output (web-search / MCP / read dumps) flooded the transcript.
Now a tool result whose output exceeds the live body cap renders collapsed by
default — head + a "▸ N lines — click to expand" footer — and you click the card
(while it is live) to expand (▾) / collapse. Mirrors the existing reasoning-row
collapse, so collapsed rows also flush to scrollback clean.

Scoped to avoid hiding what matters:
  - diff tools (edit_file / apply_patch / write_file) never collapse — their body
    must stay reviewable (matches the deeper flush cap intent);
  - the uncapped detailed transcript view (Ctrl+O, bodyCap==0) never collapses —
    it still shows full output;
  - short output (<= cardBodyMaxLines) stays inline as before.

Reuses transcriptRow.expanded + the row toggle (toggleReasoningRow generalized to
toggleTranscriptRow); the card head is a clickable toggle line. Running tool
cards (spinner) are unchanged.

Tests: collapse/expand, short-output inline, diff tools never collapse, toggle,
and the head exposes a click toggle; existing diff + detailed-view tests updated.
Gates: gofmt/vet/build(host+linux+windows)/tui -race/staticcheck all clean.

* cli: fall back to a usable saved provider instead of re-running onboarding

If the active provider lacked a credential (e.g. it relies on an env var that
isn't set, or an OAuth login that isn't stored), the TUI forced first-run
onboarding on every launch — even when other saved providers were fully
configured. Each onboarding then appended yet another provider.

Now, when the active provider isn't usable, fall back to the first usable saved
provider (prefer a remote keyed one over a local endpoint) for the session, and
skip onboarding. Onboarding only runs when no configured provider is usable — a
genuinely fresh setup. Saved logins persist; switch the active provider with
`zero provider use <name>`.

Tests: firstUsableProvider prefers remote keyed, falls back to local, accepts a
keyless local proxy, and reports none-usable. Gates: gofmt/vet/build
(host+linux+windows)/staticcheck clean; the only failing cli tests
(doctor/exec, network-dependent) are pre-existing on origin/main.

* tui: hold the scroll position while output streams in

The chat viewport scroll offset is measured from the bottom, so when the
transcript grew (a streaming turn) the window followed the new bottom and yanked
the user off whatever they had scrolled up to read.

syncChatScroll now pins the viewport: while the user is scrolled up, it bumps the
offset by however many lines the body grew, so the absolute view holds where they
are reading; at the bottom (offset 0) it follows the tail as before. Hooked into
the single Update funnel; only the scrolled-up path renders the body, so the
common (at-bottom) case stays cheap.

Tests: pins by the growth delta while scrolled up; resets/follows at the bottom.
Gates: gofmt/vet/build(host+linux+windows)/tui -race/staticcheck clean.

* agent: search the web proactively instead of answering "I don't know"

When a web search/fetch tool is available and the user asks about something
external the model is unsure of or that may be current (a product, library,
company, price, version, recent event), the system prompt now tells it to search
and read results before answering, rather than replying that it doesn't know
without checking. Addresses the model saying "I don't know about that" until the
user explicitly asked it to search.

Tests: prompt includes the new guidance ("search the web and read"). Existing
prompt assertions use Contains, so the addition is non-breaking.

* tui: show clean labels for MCP tool cards (mcp_exa_web_search_exa → web search)

* agent: sharpen web-search guidance (disambiguate, refine, scale)

Strengthen the search rule so the model searches before answering about an
external entity/product/library/model/version/release it doesn't recognize,
doesn't assume the most common meaning of an ambiguous name (disambiguates by the
conversation's domain), and refines + re-searches when results look off-topic —
rather than confidently answering the wrong interpretation (e.g. reading "Fable 5"
as a video game instead of an AI model). Also: don't web-search timeless facts or
workspace-answerable questions (use the file tools), keep queries short, and scale
the number of searches to the question.

Tests: prompt includes the new guidance ("search the web before answering",
"do not recognize"). Existing assertions use Contains, so non-breaking.

* test: gofmt setup_fallback_test.go (comment alignment)

* Address review feedback on web_search + chat UX

Resolve CodeRabbit review comments on this PR:

- firstUsableProvider: skip a profile whose CatalogID no longer resolves
  *and* that has no explicit BaseURL (no endpoint → unusable). A stale
  CatalogID with a BaseURL still works as a custom endpoint and is kept.
- providerProfileIsLocal: classify by parsed URL hostname (exact
  localhost / 127.0.0.1 / ::1) instead of substring matching, so hosts
  like "notlocalhost.com" are no longer misread as local.
- lenientScore: reject non-finite scores (ParseFloat accepts "NaN"/"Inf")
  so the documented score filter actually holds and the renderer never
  emits a non-finite value.
- syncChatScroll: shift the pinned from-bottom offset by the signed line
  delta so the view also holds when the body shrinks (card collapse,
  transcript clear), clamped at zero; previously only growth was handled.
- copyTranscriptSelectionCmd: report "Copy failed" when both the native
  clipboard and the OSC52 fallback fail, instead of claiming success;
  keep the selection so the user can retry.
- Drop vestigial ZERO_WEBSEARCH_BACKEND test env: the native backend was
  removed (MCP path), so the var is read by no product code and the
  references misrepresented it as a config knob.

Adds tests for the local-host parsing, the catalog/BaseURL skip, and the
non-finite score rejection.

Anandan 2bcb85bfb3 Polish TUI title bar (#219)
* Polish TUI title bar

* Show PR diff stats in TUI title bar

Add a small PR status service that detects the active GitHub PR or GitLab merge request via gh/glab, computes diff stats against the PR base with git diff --shortstat, and publishes updates to the TUI.

Render the resulting +N -N #PR segment in the title bar next to the branch, linked to the PR URL, while keeping the composer footer unchanged.

Tested: GOCACHE=/tmp/zero-go-cache go test ./internal/tui

Tested: git diff --check

* Make submitted prompt bubble terminal-safe

Replace half-block top/bottom rows in submitted user prompts with background-filled padding rows. macOS Terminal renders the half-block glyphs as visible horizontal artifacts, while filled-space padding keeps the prompt bubble height without relying on ambiguous block glyph behavior.

Update selectable transcript rendering to use the same padding helper and remove the now-unused half-block theme style.

Tested: GOCACHE=/tmp/zero-go-cache go test ./internal/tui

Tested: git diff --check

KRATOS f857c4afb4 feat(daemon): TLS remote bridge — authenticated network access to the daemon (#211)
* feat(daemon): TLS remote bridge — authenticated network access to the daemon

Add internal/daemon/remote: an OPT-IN, TLS-only network bridge on top of the
local daemon. A remote client drives the SAME SessionManager/Pool over the
network behind bearer-token auth, reusing the daemon's framing and dispatch
unchanged. The local Unix-socket daemon stays the default and is unchanged.

- Bridge: per accepted TLS connection, authenticate THEN hand to the daemon's
  control dispatch via the new Server.ServeConn seam — a remote session runs
  under the same sandbox/risk model as a local one (never bypasses it).
- Authenticator + TokenAuthenticator: constant-time bearer-token check, token
  from $ZERO_DAEMON_REMOTE_TOKEN or a file; optional attestation hook (no-op
  default). Auth happens before any control frame; failure closes the connection
  after a small backoff; tokens are never logged.
- RemoteClient (DialRemote): verified TLS dial (never InsecureSkipVerify) + auth
  handshake, then the existing daemon.Client via the new NewClientConn seam, so
  remote and local share one protocol.
- Fail-closed: TLS mandatory (refuses without cert/key), a configurable
  min-protocol-version floor, the 1 MiB frame cap reused, and a bounded
  concurrent-connection cap that refuses overflow.
- CLI: `zero daemon serve-remote --addr --tls-cert --tls-key`; `run`/`attach`
  gain `--remote <addr> [--token --ca-cert --server-name]`.

Daemon seams added (additive, behavior unchanged): Server.ServeConn,
NewClientConn. SessionLink (event POST) and git-bundle repo transfer are
documented follow-ups.

Tests cover auth accept/reject (env + file), TLS-required, cert verification,
version floor, run/status/attach round-trip, re-attach resumption, connection
cap, and ListenAndServeTLS/Close. Gates: gofmt / vet / build (host+linux+
windows) / test -race / staticcheck (no new) / govulncheck (0) / deadcode
(no new) all pass.

* swarm: de-flake TestMailboxConcurrentSends on Windows CI

The 200-way concurrent-send stress test inherited from the swarm package timed
out on Windows CI (103/200 sends hit the 10s lock timeout): the lock's 20ms
retry sleep starves waiters when Windows file ops are slow under heavy
contention. Shorten the retry to 2ms (a freed lock is re-acquired promptly) and
raise the test's lock timeout to 60s so a legitimately-slow CI never times a send
out. Passes repeatedly under -race. (CI de-flake of a test that surfaced on
#210's Windows smoke; functionally unrelated to the OAuth changes.)

* remote: address CodeRabbit re-review (TLS dial + Close idempotency)

- client: replace the deprecated, non-cancellation-aware tls.DialWithDialer with
  a context-aware tls.Dialer.DialContext (resolves the golangci-lint noctx CI
  blocker; the context bounds the dial + TLS handshake).
- bridge: Close now clears b.listener under the lock, so a repeat Close is a
  no-op instead of returning a closed-listener error (matches its doc). Test
  asserts a double Close succeeds.

Gates: gofmt/vet/build(host+linux+windows)/test -race/staticcheck(no new)/
govulncheck(0)/deadcode(no new) all pass.

KRATOS bb7de29c80 feat(oauth): reusable provider OAuth engine + zero auth CLI (#210)
* feat(oauth): reusable provider OAuth engine + `zero auth` CLI

Add internal/oauth: a transport/identity-agnostic OAuth 2.0 engine that powers
provider login alongside the MCP-server OAuth zero already has. It is additive
and provider-neutral — NO providers, endpoints, or client identities are baked
into the binary; every provider is configured entirely via ZERO_OAUTH_<NAME>_*
env vars, so the engine works with any OAuth 2.0 / OIDC server.

Engine (internal/oauth):
- PKCE (S256 mandatory; "plain" refused) + per-flow CSRF state.
- Authorization-code flow: BuildAuthorizationURL / ExchangeCode / Refresh, with
  an https-only token-endpoint guard (loopback exempt) and error bodies that
  carry only error/error_description (never token material).
- Loopback callback server: 127.0.0.1-only, OS-assigned port, single use, state
  verified, then closed.
- Device-authorization grant (RFC 8628): RequestDeviceCode + PollDeviceToken
  honoring authorization_pending / slow_down / interval / expiry (headless/SSH).
- RFC 8414 + OIDC discovery (issuer-driven endpoint resolution).
- Namespaced token store ("provider:<name>" / "mcp:<name>"), 0600, file-locked
  (ownership-aware), atomic writes, malformed-fails-closed; GetFresh (on-demand
  refresh) + Handle401 (forced refresh).
- Opt-in proactive RefreshScheduler.

CLI (zero auth):
- login <provider> [--device] [--scope ...], logout, status [provider],
  refresh <provider> [--watch]. Status/output never print token material.
- Registered in app.go dispatch + top-level help.

MCP OAuth (internal/mcp) is left byte-for-byte unchanged (zero regression);
sharing the engine with MCP and encrypted-at-rest/keyring storage are documented
follow-ups. Tests cover every path (PKCE, auth URL, https-guard + redaction,
exchange/refresh, loopback capture + state-mismatch + timeout, device pending/
slow_down/expired, store namespacing/0600/locking, provider env resolution,
manager login (loopback+device)/GetFresh/Handle401, scheduler). Gates: gofmt /
vet / build (host+linux+windows) / test -race / staticcheck (no new) /
govulncheck (0) / deadcode (no new) all pass.

* oauth: fix Windows smoke — use OS-appropriate path in store-path test

TestResolveStorePathHonorsOverride hardcoded a unix "/tmp/custom/tok.json"
literal, which is not absolute on Windows (no drive), so ResolveStorePath
correctly resolves it against the current drive and the verbatim comparison
failed (D:\tmp\custom\tok.json). The production code is correct; the test now
builds the override with filepath.Join(t.TempDir(), ...) so it is absolute and
clean on every OS.

* oauth: address CodeRabbit review (11 findings)

Security / correctness:
- flow: caller-supplied ExtraAuthParams/extraParams can no longer override the
  reserved OAuth/PKCE fields (state, redirect_uri, code_challenge[_method],
  response_type, client_id) — e.g. forcing method=plain.
- device: a device-authorization response without expires_in now gets a bounded
  default lifetime (fail closed), and the poll loop re-checks expiry AFTER the
  interval sleep so it never polls past the deadline (e.g. after slow_down).
- lock: handle WriteString/Close errors on the token lock file — a partial write
  no longer strands an undeletable lock.
- store: a non-nil env map is now authoritative (hermetic) — a controlled map
  never falls back to ambient ZERO_OAUTH_* / HOME / XDG_CONFIG_HOME.
- scheduler: a transient loadForKey error backs off and retries (bounded) instead
  of permanently stopping proactive refresh.
- cli auth: reject flags a subcommand does not accept (e.g. login --watch,
  status --device) and reject empty --scope values — fail fast.

Lint blockers:
- manager: restructured the discovery fallback so the non-nil-err branch no longer
  returns nil (nilerr).
- providers: dropped the ineffectual flow initializer (ineffassign).

Tests: assert Save/Load errors in the scheduler test; the slow_down device test
no longer depends on post-expiry polling. Added tests for reserved-param
stripping, hermetic env, device default-expiry, and CLI flag validation. The
store-path test was already made OS-portable in the Windows-smoke fix.

Gates: gofmt/vet/build(host+linux+windows)/test -race/staticcheck(no new)/
govulncheck(0)/deadcode(no new) all pass.

* swarm: de-flake TestMailboxConcurrentSends on Windows CI

The 200-way concurrent-send stress test inherited from the swarm package timed
out on Windows CI (103/200 sends hit the 10s lock timeout): the lock's 20ms
retry sleep starves waiters when Windows file ops are slow under heavy
contention. Shorten the retry to 2ms (a freed lock is re-acquired promptly) and
raise the test's lock timeout to 60s so a legitimately-slow CI never times a send
out. Passes repeatedly under -race. (CI de-flake of a test that surfaced on
#210's Windows smoke; functionally unrelated to the OAuth changes.)

* oauth: address CodeRabbit re-review (4 findings)

- loopback (security): NewLoopbackListener refuses an empty CSRF state — an empty
  state would match a callback carrying no state at all, defeating the check.
- device (correctness): RequestDeviceCode now sends client_secret when set, so a
  confidential client authenticates on the device-authorization endpoint too
  (consistent with the token poll).
- cli auth: document --watch in the help Flags section.
- scheduler test: assert the seed Save error instead of ignoring it.

Also scrubbed a stray third-party reference from a loopback.go comment.
Tests added: empty-state rejection, device client_secret is sent. Gates:
gofmt/vet/build/test -race/staticcheck(no new)/govulncheck(0)/deadcode(no new)
all pass.

* mcp(oauth): delegate the OAuth engine to internal/oauth (dedup) (#212)

OAuth Phase 2: the MCP OAuth code now reuses the shared internal/oauth engine
instead of carrying its own copy of the transport/identity-agnostic primitives.
internal/mcp/oauth.go drops ~110 lines (526 -> 418): newPKCE, newState,
discoverAuthorizationServer, the authorize-URL builder, token exchange/refresh,
the token-response parser, and joinWellKnown now delegate to internal/oauth.

Behavior-preserving: MCP keeps its own OAuthConfig/StoredToken types,
LoginOptions/Login orchestration, loopback handling, registerClient (dynamic
client registration — not part of the shared engine), CLI output, and on-disk
token format (mcp-oauth-tokens.json, raw server-name keys). The existing mcp
oauth tests pass UNCHANGED. The only behavioral delta is a hardening inherited
from the shared engine: the token endpoint must be https (loopback exempt) —
a credential is no longer sent to a plaintext non-loopback endpoint.

Stacks on #210 (the internal/oauth package). Gates: gofmt/vet/build(host+
linux+windows)/test -race/staticcheck(no new)/govulncheck(0)/deadcode(no new
vs base) all pass; `zero mcp oauth status` output is identical.

de5d402e1f web_search: add domains allowlist + score field (#209)
* web_search: add domains allowlist + score field

The web_search tool now accepts an optional 'domains' array that filters
results to the listed hostnames before they reach the model. This is the
zero-only prompt-injection defense that none of the major CLIs ship: a
model that the user has constrained to a known-good set of domains cannot
be tricked into fetching arbitrary pages from search results.

Also surfaces the provider's optional 'score' field on each result row
when present (zero/absent scores are not rendered, to keep the common
case tidy). The 'score' field is parsed from the generic JSON shape
already understood by the httpSearchBackend.

Filters are applied after the search returns, before the empty-result
short-circuit, so a non-empty allowlist that ate every hit surfaces as a
clear 'no results matched domains' error rather than a misleading
'no results' message.

Co-Authored-By: Claude <[email protected]>

* web_search: fail closed on all-invalid domains, strip :port on canonicalize

CodeRabbit review fixes:

1. canonicalizeWebSearchHost: switch parsed.Host -> parsed.Hostname() so
   an allowlist entry like 'https://react.dev:443/path' normalizes the same
   as 'react.dev'. The previous code left ':443' in the string, which
   silently broke every match against a result URL on the default port.

2. stringListArgWebSearch: return a 'provided' bool so Run can distinguish
   'no allowlist' from 'allowlist that normalized to empty'. The previous
   code returned len(domains)==0 in both cases, and Run fell through to
   the unfiltered path — defeating the prompt-injection defense the
   parameter exists to provide. Now we error fail-closed.

3. Tests:
   - TestWebSearchDomainsFilterRejectsAllInvalidInputs: locks in the
     fail-closed contract for all-whitespace, all-empty, embedded-space,
     and mixed-invalid allowlists.
   - TestWebSearchDomainsFilterAcceptsHostPort: locks in the
     Hostname()-strips-port fix for the scheme'd case and asserts that
     scheme-less 'host:port' is rejected.
   - TestCanonicalizeWebSearchHostStripsPort: the direct unit-level
     regression test for canonicalizeWebSearchHost.

KRATOS 9ddef0e957 feat(swarm): multi-agent swarm over the specialist sub-agent (#207)
* feat(swarm): multi-agent swarm over the specialist sub-agent

Add internal/swarm so an orchestrator can spawn and coordinate MULTIPLE
specialist members concurrently under one team, communicate via per-agent
mailboxes, hand work off, and adopt orphaned tasks. Additive and opt-in: the
single Task tool is unchanged; swarm tools only act when invoked.

- Registry/Definition: agent roster (built-in teammate/subagent + user-defined).
- Mailbox: per-team/per-agent JSON inbox, owner-only 0600, file-locked with
  stale-break, size-capped, path-confined, and malformed-fails-closed.
- Coordinator: in-memory task registry with terminal-state guards and stable
  per-agent colors.
- Team: bounded concurrent members per team with a FIFO overflow queue that
  drains one-per-slot.
- Lifecycle: spawn / handoff / orphan-adoption with bounded relaunch on
  temporary failures; members run under the Swarm's base context so they
  outlive the spawn call.
- Tools: swarm_spawn, swarm_send, swarm_inbox, swarm_status, swarm_handoff,
  swarm_collect.
- Wiring: each member is launched through specialist.Executor and inherits the
  orchestrator's model + permission mode (never widened) and runs under the same
  sandbox/policy. Mailbox state lives under the workspace so writes fall within
  the sandbox write rules. Swarm lifetime is paired with the specialist runtime.

Scheduling (cron/wakeup) and daemon-pool-backed members are deferred follow-ups.

* swarm: address CodeRabbit review (7 findings)

- coordinator: SetStatus rejects unknown TaskStatus values (fail closed) so a
  task can never enter a state Summarize/lifecycle don't reason about.
- permission inheritance ENFORCED end-to-end (was resolved but discarded):
  thread PermissionMode through specialist.TaskRunOptions -> BuildArgs/
  BuildResumeArgs. A headless specialist child now runs "--auto high" (unsafe)
  ONLY when the parent is unsafe or no mode is given (preserves the Task tool's
  behavior); any other parent mode yields non-unsafe "--auto low", so a member
  never gains more authority than its orchestrator. Also fixed the swarm
  permission vocabulary to the real agent runtime modes (ask/spec-draft/auto/
  unsafe) instead of TUI display names, and the launcher substitutes "auto" for
  an empty mode so a member can't fall into the empty-means-high path.
- mailbox: symlink-aware confinement (EvalSymlinks) rejects an inbox dir that
  resolves outside BaseDir; dirs tightened to 0700 even if pre-existing with
  broad perms; lock release is ownership-token-aware so a stale-broken writer
  can't delete a newer writer's lock (split-brain).
- member: recover panics inside a member goroutine -> fails that member only,
  never crashes the orchestrator.
- tools: collapse() truncates on rune boundaries (no invalid UTF-8).

Tests added for every fix. Existing specialist behavior is unchanged (empty
PermissionMode keeps --auto high). Gates: gofmt/vet/build (host+linux)/test
-race/staticcheck(no new)/govulncheck(0)/deadcode(no new) all pass.

* swarm: address review round 2 (Windows lock + non-blocking notes)

Blocking (Vasanth): mailbox acquireLock now treats Windows ERROR_ACCESS_DENIED
/ ERROR_SHARING_VIOLATION as lock-contended (retry/wait) instead of a fatal
error, via a platform-aware isLockContended (lock_windows.go / lock_other.go).
A contended lock under Windows file-sharing semantics no longer fails a
send/read spuriously. TestMailboxConcurrentSends raised to 200 goroutines with a
10s lock timeout and now asserts zero send failures (regression guard).

Non-blocking notes addressed:
- Removed third-party reference-project names from doc comments (clean-room +
  provider-neutral); the Go code is original.
- Documented the inbox-file size bound's ×2 (pretty-print overhead) constant.
- Documented Send's O(N) rewrite cost + when to switch to append-only.
- permissionRank: spec-draft now ranks below ask (it never widens authority).
- Documented watch's per-member-id retry binding (Member.ID == MemberSpec.ID).
- handoff Safety.Reason now also mentions the inbox write.

Gates: gofmt · vet · build (host+linux+windows) · test -race · staticcheck
(no new) · govulncheck (0) · deadcode (no new) all pass.

KRATOS ba8fbb8b71 feat(sandbox): complete sandbox breadth — WSL fallback + opt-in MITM TLS inspection (#206)
* feat(sandbox): complete sandbox breadth — WSL fallback + opt-in MITM TLS inspection

Adds the two remaining sandbox features on top of the strict fail-closed core
(the other four — SOCKS5 egress, re-entrancy guard, fine-grained path lists,
sandbox-aware ripgrep — already shipped and are untouched). Both new features are
opt-in and the DEFAULT policy is unchanged (enforce + network deny, InspectTLS
off; AllowPolicyOnlyRunner keeps its existing default).

1) WSL detection + safe fail-closed fallback
   - parseWSL/detectWSL (wsl.go + wsl_linux.go reading /proc/version; wsl_other.go
     stub) classify WSL/WSL2.
   - SelectBackend: on Linux without bubblewrap, if running under WSL it selects a
     new BackendWSL instead of silently degrading to a plain policy-only runner.
   - BuildCommandPlan(BackendWSL): FAILS CLOSED unless Policy.AllowPolicyOnlyRunner
     is set (errWSLPolicyOnlyDisabled explains how to opt in). When allowed it runs
     the policy-only fallback that still routes egress through the filtering proxy
     (Backend.ProxyEgress => EnforcesScopedEgress, best-effort HTTP+SOCKS), sets
     ZERO_SANDBOXED=1 / ZERO_SANDBOX_BACKEND=wsl, and records an auditable
     least-privilege downgrade note (CommandPlan.Notes). Never runs unsandboxed
     silently.

2) Optional gated MITM TLS inspection (Policy.InspectTLS, default OFF)
   - Off => the egress proxy is a pure CONNECT passthrough, byte-for-byte
     unchanged (no CA generated).
   - On => the proxy terminates TLS toward the sandboxed client with an EPHEMERAL,
     locally generated ECDSA CA (mitm.go), minting per-host leaves on the fly, so
     it can re-check the DECRYPTED request Host through the SAME
     authorize()/domainAllowed() gate (deny-wins, empty allowlist => deny) — MITM
     widens visibility, never authority. The UPSTREAM dial is ALWAYS validated
     against the system roots (never InsecureSkipVerify; tests inject a known root
     pool to exercise validation). The CA's PUBLIC cert is written owner-only and
     surfaced via ZERO_SANDBOX_CA_CERT; MITM only runs on backends that already
     permit reading it (sandbox-exec allows file-read; WSL shares the host fs), so
     no new bind path is introduced. Trust implications documented loudly on the
     field. (No "raw passthrough only" flag exists in zero, so the mutual-exclusion
     case is N/A.)

Tests: parseWSL table; WSL fail-closed-without-opt-in and policy-only-with-proxy
(markers + ProxyEnvWithSocks) + deny-mode markers-no-proxy; MITM passthrough-by-
default (no CA), CA mints a chaining leaf, full TLS-terminate-and-forward of an
allowlisted host (upstream validated via an explicit root pool), and decrypted-
Host deny. Gates: gofmt, go vet (host + GOOS=linux), go build (host/linux/
windows), go test (incl -race), staticcheck (no new, host + linux), govulncheck
(0), deadcode -test=false under GOOS=linux (no new unreachable funcs).

* sandbox: address review on #206 (WSL + MITM)

- mitm: bound the upstream transport's TCP connect (DialContext 30s) so a
  blackholed upstream can't park a goroutine; disable upstream HTTP/2 and
  normalize the response to HTTP/1.1 before writing to the HTTP/1.1 client.
- mitm: mint leaves for the AUTHORIZED CONNECT host (not arbitrary client SNI)
  and cap the leaf cache (512) so SNI churn can't drive unbounded keygen/memory.
- mitm: re-check the decrypted Host with the FULL authorize gate
  (authorizeTarget) so a DomainPrompt-allowed host is honored consistently with
  the CONNECT check, not just domainAllowed.
- runner (WSL): preserve the caller's env in the direct-run WSL plan (it is not
  OS-wrapped), appending the sandbox markers last; the downgrade note says
  "with proxy egress" only when a proxy was actually started.
- tests: WSL caller-env preservation; deny-mode asserts no HTTP/HTTPS/ALL_PROXY
  leak + the downgrade note; MITM forward asserts HTTP 200; mitmConnect sets an
  I/O deadline.

Gates: gofmt, vet (host+linux), build (host/linux/windows), test (incl -race),
