euxaristiaandeuxaristia b76c764b77 fix(providerio): close idle connections periodically to prevent HTTP/2 PROTOCOL_ERROR (#1058)
* fix(providerio): close idle connections periodically to prevent HTTP/2 PROTOCOL_ERROR

OpenRouter and other HTTP/2 backends can silently reset or drop connections
that sit idle in Go's client connection pool across user turns. When a
subsequent turn reuses the stale connection, it fails on stream connect with
PROTOCOL_ERROR.

Launch a background idle connection closer on non-darwin platforms to evict
idle pooled connections on a 30-second interval, forcing fresh handshakes
after idle pauses while preserving connection reuse across fast agent turns.

Refs #1057

* test(providerio): poll for idle connection eviction with bounded deadline

Replace the fixed 60ms sleep in TestStartIdleConnCloserClosesIdleConnections
with a 2-second bounded polling loop to avoid test flakes under heavy CI
load or under the race detector.

Vasanth T 91d921f4c5 feat(tui): offer mid-run model escalation behind --allow-escalation (#1019)
* feat(tui): offer mid-run model escalation behind --allow-escalation

Mid-run escalation existed but only exec offered it. The TUI already handled
every consequence of a switch, re-deriving the compaction threshold "after a
mid-run escalate_model switch" and resolving the summarizer against the active
profile, while nothing on that surface could cause one: escalate_model was
registered by exec alone. This closes that, opt-in, the same conservative way
exec answers the question.

Opt-in rather than default because escalation moves a run onto a different model,
which changes what it costs and which provider sees the conversation. That is the
operator's call, and the exec flag already answers it.

The switchers are built per turn from m.providerProfile rather than once at
launch. A TUI session can change models with /model, so a closure capturing the
startup profile would escalate from whatever the session began with instead of
what is in force now, and would carry that stale profile's base URL and
credential with it. exec has no such problem because its profile cannot change
mid-run, which is why the wiring lives in different places on the two surfaces.

The nil-contract logic is now shared rather than copied. providers.
EscalationSwitchers is the single implementation both surfaces call: the loop
swaps only on a non-nil provider, so a (nil, nil) return has to leave everything
untouched including the caller's usage attribution, and the session switcher is
installed only when the run STARTED optimized so escalation cannot change the
transport underneath a session. A second copy of that would only ever have been
exercised on one surface. exec's behaviour is unchanged: its six existing
escalation tests pass against the shared builder.

The tool and the switchers ride on one flag and a test asserts they cannot be
separated. Registering escalate_model without wiring a switcher ships a tool the
loop silently ignores, so the model reports an escalation that never happened;
that is the specific failure worth a guard rather than a comment.

Note this does not answer all of #554. Assigning models per phase, plan with one
and execute with another, is still not built. This makes the mechanism reachable
from the interactive surface, which is the part that was one flag away.

Refs #554

* fix(tui): attribute usage after an escalation to the model in force

exec reassigns currentModel when the escalation switcher fires; the TUI
captured usageModelID once per run and handed the switcher no callback,
so every usage event after a mid-run escalation was billed to the model
the run started on. The switcher now updates usageModelID, and the final
response carries the model per usage event so the batch fallback does
not swing the other way and bill the events before the switch to the
escalated model. Covered by a run through a scripted escalation that
checks both the live and the batch attribution.

* fix(cli): accept the root flags in any order

Each leading-flag splitter stops at the first token it does not own, so
running them once in a fixed sequence made the order load-bearing:
`zero --allow-escalation --theme auto` stranded the theme as an unknown
command and exited with an argument error instead of launching, and the
same happened after --skip-permissions-unsafe. The three splitters now
run until they make no progress, at the root and after the unsafe flag,
so every ordering reaches the TUI with every flag applied. A --theme
written before --skip-permissions-unsafe was dropped on that path; it is
kept now, with a later one winning as the last occurrence does.

* fix(cli): forward a root --allow-escalation into exec, reject it elsewhere

The root flag was stripped before dispatch, so `zero --allow-escalation
exec ...` and `zero --allow-escalation -p ...` ran without the opt-in the
help text promises, and `zero --allow-escalation version` accepted a flag
it could only discard. It now follows --add-dir: re-synthesised into the
exec argument list for the exec and -p shapes, so exec parses it as its
own flag, and rejected loudly for every other command. The ordering test
now generates every permutation of the three root flags, with
--skip-permissions-unsafe absent or at any position.

* fix(tui): record the model on an escalated run persisted usage events

The live usage record carried the model in force; the persisted session
payload did not. The usage report rebuilds cost from that payload and
falls back to the session-wide model when an event does not name one, so
an escalated interactive run was priced end to end at the model it started
on. Written only under escalation, matching what exec records under the
same flag, so an ordinary run persists the same compact payload as before.

* test(cli): isolate the new launch helpers from real user state

A temporary working directory isolates project files and nothing else.
runWithDeps fills the dependencies a test leaves out with production ones,
and the interactive launch path reads user config, opens stores, refreshes
the models.dev cache and migrates any inline plaintext API key into the
credential store before it reaches an injected runTUI callback. Running
these tests on a developer machine therefore rewrote that developer's
config.json and wrote a credential file beside it, and the results depended
on whatever providers, MCP servers and plugins the machine had.

Both new helpers now point every per-user base directory at a throwaway
root, pin the models.dev cache path, disable its background fetch, and
force the file credential backend so nothing reaches the host keyring. A
new test seeds a config with an inline key outside those fixture roots and
fails if either helper rewrites it or leaves a file beside it; without the
isolation it reports the rewritten config and the credentials.enc files.

* test(cli): check each launch helper isolation on its own

t.Setenv restores at the end of the test, not when the helper returns, so
one test exercising both helpers let the first isolation cover for the
second. Each helper now seeds its own emulated user config in a subtest,
and removing the isolation from either one fails that subtest.

* test(cli): pin the isolation itself, not only what this platform writes

The exec helper writes its models.dev cache from a background goroutine,
so a footprint check could not prove its isolation deterministically. Each
subtest now also asserts the helper moved the per-user paths off the
seeded root and disabled the fetch and the keyring backend, which fails
for either helper when the isolation call is removed.

Kevin CodexandClaude Fable 5 6645f9744b perf(agent): cheap compaction — dedicated summarizer model, input cap… (#532)
* perf(agent): cheap compaction — dedicated summarizer model, input caps, free reactive prune, window re-derive

Compaction summarization was the single most expensive recurring event
in a long run: the full elided middle — verbatim tool bodies included —
went to the session's main model at full price (a ~100k-token call near
a 200k window, recursively multiplied on overflow).

Four changes, each independently safe:

- Dedicated summarizer model. Compaction summaries route to a cheap
  model resolved as ZERO_COMPACTION_MODEL > preferences.compactionModel
  > a curated default on official endpoints (Haiku 4.5 / Gemini
  Flash-Lite / gpt-4.1-mini; custom-endpoint catalogs are unknowable so
  they get none). Built lazily on the first paid compaction; ANY
  failure permanently falls back to the main provider for the run, so a
  misconfigured summarizer can never break compaction. "main" at any
  level forces the old behavior.

- Summarizer input caps. renderTranscript clamps tool-result bodies to
  2,000 chars and tool-call arguments to 500 (head+tail, rune-safe) —
  the summary needs what was done and decided, not raw payloads. Cuts
  summarizer input 5-10x on tool-heavy sessions.

- Free reactive prune. recover() now runs the same prune-first stage as
  the proactive path: a context-limit error is first answered by
  pruning stale tool bodies at zero cost, without consuming the
  one-shot reactive budget; the paid summarizer only runs when a later
  error finds nothing left to prune.

- Window re-derivation on model switch. Options.ContextWindowFor
  (wired to the model registry in exec and the TUI) lets the loop
  re-derive the compaction threshold after escalate_model, closing the
  documented KNOWN LIMITATION where a switch to a smaller-window model
  could overflow and a larger one over-compacted.

## Rebase notes (2026-08-25, onto 2749447c)

Rebased across 214 commits. main now summarizes through the context planner
(#879) and switches models via turn sessions, so the agent side was reworked
rather than merged textually:

- Summarizer selection lives on compactionState and is resolved lazily per
  main model through summarizeWithPlanner (planner + trace preserved); a
  failing dedicated summarizer is marked broken and the same slice is
  retried once on the main provider.
- Options.Summarizer now receives the main model in force:
  `func(ctx, mainModelID string) (Provider, error)`, and may return
  (nil, nil) when no dedicated model applies. After a successful
  escalate_model switch the loop calls compactor.switchModel, which
  re-derives the window and re-resolves the summarizer — a run that started
  on the cheap model and escalated regains cheap summaries (review P2).
- recover()'s free prune stage runs before the one-shot reactive guard
  (pruning is free and cannot loop) and mirrors maybeCompact's two prune
  passes; the free retry is taken only when the pruned history fits the
  window the provider enforces (with a 5% estimate margin), otherwise the
  same call falls through to the paid summarizer. Gating on the 70%
  proactive threshold would have sent histories in the 70-95% band to the
  summarizer unnecessarily (review P1 and the follow-up question).
- ContextWindowFor is wired through the turn-session switch path; the
  planner's window is updated alongside the compactor's.

Tests: the PR's suite is ported to the new seams, plus insufficient-prune
fall-through, free prune after the budget is spent, window-vs-threshold
gating, and summarizer re-resolution across a model switch.

* fix(agent): branch on a dedicated-summarizer flag instead of comparing providers

Review follow-ups for #532:

- summarizeProvider now reports whether the dedicated summarizer was
  selected and summarizeClosure branches on that flag; the previous
  `chosen == provider` compared Provider interface values, which panics
  when the dynamic type is not comparable. Regression test uses a provider
  with a slice field for both the summarizer and the main provider.
- CompactionModelID's curated-default test covers the official OpenAI
  profile alongside Anthropic and Google.

Eli Lap 1a81292d3f Fix LM studio (local) model discovery. (#918)
* Fix LM studio (local) model discovery.

* fix(openai): handle typed-nil properties in normalizeToolParameters

The `properties == nil` interface comparison misses typed-nil
`map[string]any` values, which JSON-serialize as `null` instead of
`{}`. Strict OpenAI-compatible servers (LM Studio) reject the request.

Type-assert first, then compare the underlying map, so a typed-nil
properties field is rewritten to an empty object. Adds a regression
test that exercises the typed-nil path.

* test(openai): cover non-map properties in normalizeToolParameters

CodeRabbit follow-up on the typed-nil fix: lock in the behavior
when `properties` is a non-map value (e.g., empty slice) so the
type-assert branch normalizes it to an empty object on the wire.

* chore: remove dead wrapper functions and unused test seams

These five functions are unreachable from any cmd/* main even when tests are included (deadcode -test ./...), so they are genuinely dead on every platform:

- TraceEventKeys: one-line alias of ParseTraceEventKeys, no callers
- ValidateToolCapabilities: one-line alias of ValidateCapabilities, no callers
- GetLocalDiffStats and WatchPRState: test seams in internal/tui/export_test.go that no test calls
- ScanSSEData: non-context SSE scanner in internal/providers/providerio, fully superseded by ScanSSEDataWithContext

The five remaining -test findings are //go:build !linux stubs (landlock/seccomp/linux_helper) that are live on Linux, so they are left in place.

Vasanth T 8acd42a3bd fix(providers): retry provably pre-send transport failures (#447) (#750)
* fix(providers): retry provably pre-send transport failures (#447)

A flaky link that failed the streaming completion POST at connect time
stopped the turn and forced a manual continue, because the shared retry
layer never retries transport errors: a completion POST is
non-idempotent, so a replay could duplicate billable work.

That rationale does not apply to a PROVABLY pre-send failure, where no
request bytes ever left this host: a replay cannot duplicate anything,
exactly like a 429/503 where the server told us it did not accept the
request. SendWithRetry now retries, with the existing backoff, only that
narrow class: DNS resolution failure, a refused or unreachable dial, and
a TLS handshake timeout. Every ambiguous or post-send failure stays
unretried and is checked first so a mixed message can never be misread:
connection reset, broken pipe, EOF, a bare i/o timeout, context
deadline. All three providers route their completion POST through this
layer, so one change covers them uniformly.

This deliberately narrows the issue's ask (which listed connection
reset) to the provably-safe subset, and keeps the reset-stays-unretried
test green. Tests cover the retry-on-pre-send, no-retry-on-ambiguous,
and predicate-classification paths.

NOTE FOR REVIEW: this refines a deliberately conservative, documented
no-retry stance. Opening it for the owner's sign-off on the stance, not
as a settled call.

* fix(providers): classify pre-send dials by errno so Windows retries too

CodeRabbit flagged that the pre-send predicate matched only POSIX dial
wording, so a refused or unreachable dial on Windows (whose text differs
entirely: 'No connection could be made because the target machine
actively refused it') would not be retried.

Match the syscall errno via errors.Is instead: Go maps ECONNREFUSED /
ENETUNREACH / EHOSTUNREACH / ECONNRESET to the host's real values,
including the WSA codes on Windows, so classification is identical on
every platform. Errno matching is also authoritative where the string
markers were only heuristic, closing the theoretical substring gap. The
string markers stay as a fallback for errors already flattened to text.
ECONNRESET is added to the post-send exclusions by identity so a Windows
reset is excluded too.

Tests build the production error shape (net.OpError -> os.SyscallError ->
errno) so the Windows path is exercised portably on every platform, plus
an end-to-end SendWithRetry case for an errno-wrapped refused dial. Cross
-compiled and vetted for linux and darwin.

* fix(providers): scope pre-send retry to the dial phase and fail fast on permanent errors

Addresses gnanam's two [Major] review findings on this PR.

[Major] Pre-send errno classification was not scoped to the dial, so a post-send
read/write carrying ECONNREFUSED/ENETUNREACH/EHOSTUNREACH (a route dropping
mid-generation) was misclassified "provably pre-send" and could replay a
non-idempotent completion POST up to 6 times. errors.Is matches an errno
anywhere in the chain regardless of which operation raised it, so
isPreSendTransportError now requires an Op=="dial" *net.OpError before admitting
those errnos or their POSIX wording. That makes "no request bytes were sent"
structural: a post-send failure can no longer replay a POST. The dial errno
match still covers Windows (Go maps the WSA* codes), so the platform coverage
this PR added is preserved.

[Major] Permanent failures hung the agent ~60s on the 429-tuned schedule.
NXDOMAIN (net.DNSError with IsNotFound) is now treated as permanent and not
retried, and the pre-send path gets its own short bound and sub-second schedule
(preSendMaxAttempts=3, 500ms/1s) instead of reusing the 2/4/8/16/30s rate-limit
backoff, so a mistyped host or a dead local daemon fails in about 1.5s.

[Minor] Fixed the stale SendWithRetry doc that still claimed transport errors are
never replayed.

Tests: post-send read/write errnos and NXDOMAIN now assert exactly 1 call (no
replay); dial errnos plus the string fallback assert the pre-send cap; added the
pre-send backoff schedule. Race detector and all provider packages green.

* fix(providers): match Windows WSA dial errnos so refused dials retry on Windows too

CodeRabbit caught a real Windows bug, which I verified with a real dial on
Windows: errors.Is(err, syscall.ECONNREFUSED) returns FALSE for a refused dial
there, because a real Windows dial carries the raw WSAECONNREFUSED (10061) while
Go's syscall.ECONNREFUSED is a distinct value the net package never produces. The
POSIX string fallback ("connection refused") does not match the Windows wording
("No connection could be made because the target machine actively refused it")
either. So the pre-send dial classification silently never fired on Windows, the
exact platform this PR set out to fix.

Move the dial errnos into a platform-specific list (dialPreSendErrnos): POSIX
everywhere, plus the WSA* codes on Windows. The existing wrapDialErrno fixtures
wrap the Go syscall constants, which is why they passed on both platforms and
missed this. Adds TestIsPreSendTransportErrorRealRefusedDial, which does a REAL
refused dial and asserts pre-send classification, so the platform's true error
shape is exercised on every OS.

* fix(providers): exclude Plan 9 from the POSIX dial-errno build tag

* fix(providers): keep the pre-send errno classification off Plan 9

retry.go referenced syscall.ECONNRESET and dialPreSendErrnos directly, but the
errno definitions live in build-tagged files that exclude Plan 9 (which has no
BSD-style errno constants), so the package stopped compiling for GOOS=plan9 on
this branch even though it builds on the merge base.

Move the two syscall touch-points behind per-platform helpers: retry.go now
calls isConnResetErrno and ranges dialPreSendErrnos, both provided by
retry_dialerrno.go, retry_dialerrno_windows.go, and a new
retry_dialerrno_plan9.go. The Plan 9 variant supplies an empty errno list and a
false isConnResetErrno, so retry.go falls back to its existing string-marker
heuristics there. Behavior on linux/darwin/windows is unchanged (isConnResetErrno
matches the same syscall.ECONNRESET as before). retry_test.go is tagged !plan9
because it constructs real syscall.Errno dial shapes.

Verified: GOOS=plan9 build and vet now pass; windows and linux build, vet, gofmt,
and the full providerio test suite stay green.

* fix(providers): stop pre-send retry from replaying a redirected POST

Addresses jatmn's review on #750.

[P1] client.Do could follow a 307/308 after already transmitting the original
POST, and a dial failure to the redirect target then satisfied
isPreSendTransportError and replayed the request, re-billing a completion the
first host already received. SendWithRetry now disables redirect following
(CheckRedirect returns http.ErrUseLastResponse on a cloned client), so any
dial/DNS/TLS error from Do can only come from the single initial request and
the pre-send classification is sound. A 3xx surfaces as the response for the
caller's existing non-2xx handling. Regression test asserts the POST is sent
once and the 307 is not followed.

[P2] The pre-send retry used the loop-wide attempt counter shared with 429/503
retries, so a couple of status retries exhausted the pre-send budget and the
first dial/DNS/TLS blip after them got no retry. Track pre-send failures and
their backoff ordinal in a separate counter. Regression test covers a
status-then-transport-failure sequence.

[P3] Correct the Plan 9 and wrapDialErrno comments: the Plan 9 string-marker
fallback keeps the pre-send inclusions and the separate reset exclusion, and
the errno fixtures do not reproduce a real Windows dial (that carries distinct
WSA errnos), which the real-dial test covers.

* fix(providers): decouple the status retry budget from pre-send retries

Addresses jatmn's follow-up on #750.

The previous change gave pre-send failures their own counter, but every retry
still advanced the loop-wide attempt counter that the 429/503 branch used. So
the coupling survived in the opposite direction: two safely replayed refused
dials shortened the later status retry window and started its backoff at a
later rung.

Give the status path its own statusAttempts counter and backoff ordinal. With
both budgets tracked separately the shared loop counter has no remaining
reader, so the loop no longer carries one. Behaviour is unchanged when only one
kind of failure occurs: the first retryable status still waits on rung 1 and
still gets maxAttempts requests.

Adds TestSendWithRetryStatusBudgetSurvivesPreSendRetries, the inverse of the
existing mixed-sequence test: two refused dials followed by rate limiting must
still leave the status path its full window.

* fix(providers): keep following redirects, but never replay a redirected POST

Addresses jatmn's follow-up on #750.

Blocking redirects outright was too blunt. SendWithRetry is the shared
completion path, so replacing every caller's CheckRedirect with
ErrUseLastResponse turned a legitimate 307/308 from a redirecting
OpenAI-compatible gateway into a terminal non-2xx that providers report as an
upstream error, and it discarded an injected client's redirect policy.

Observe the redirect instead of preventing it: a per-attempt flag is set from
CheckRedirect, which then delegates to the caller's policy when one is set and
otherwise mirrors net/http's default ten-hop cap. The pre-send retry is gated on
that flag, so an attempt that entered a redirect is never replayed while
redirecting endpoints keep working. The safety property is unchanged, since a
dial failure on a redirect hop follows a POST the origin already received.

Adds three regressions: a redirect is followed through to the final response, a
dial failure after a redirect is not replayed, and a caller-supplied
CheckRedirect still runs and still decides.

* test(providerio): pin the redirect asymmetry for retryable statuses

A reviewer read the redirect guard as incomplete, because it stops a redirected
POST being replayed after a transport error but not after a 429/503/529. The
asymmetry is intentional, and nothing recorded that, so the next reader would
reasonably reach the same conclusion.

The two cases differ in what is known about the request. A transport failure
after a redirect leaves it unknown whether the redirect target received and
began processing the POST, so replaying could duplicate billable work. A
retryable status means every hop answered: the 307/308 is the origin declining
and delegating, and the 429 is the target declining as well, so nothing accepted
the request and a replay duplicates nothing.

The exposure is also the same as a retryable status with no redirect involved,
which this package has always retried, so guarding here would not close a gap.
It would make a rate-limited completion behind a redirecting gateway fail
outright rather than back off, which is the regression class already raised
against disabling redirects wholesale.

Adds the case as a test asserting the intended behaviour, plus a comment at the
branch explaining why it is not guarded.

* fix(providers): retry connect timeouts and proxy CONNECT failures

Three classification gaps against #447, all raised in review.

A connect-phase timeout was never retried. It is provably pre-send for the same
structural reason a refused dial is, since the connection was never established
and no request bytes left this host, but it arrives carrying "i/o timeout" and
the blanket wording exclusion rejected it before the connect gate could admit
it. Intermittent connect timeouts are exactly the transient failure the issue
is about, so the most common case was the one not covered. It is now admitted
ahead of the wording exclusions, gated on the connect phase so a post-send read
timeout, which is also Timeout(), still cannot replay a POST.

A failed CONNECT through an HTTP proxy was never retried either. net tags it Op
"proxyconnect" rather than "dial", so it missed the gate entirely. Same
guarantee applies: the tunnel to the model host was never built. The gate now
accepts both, which matters most in the environment where transient connect
failures are most common.

ETIMEDOUT and WSAETIMEDOUT join the errno lists so a connect timeout still
classifies if it reaches us with the errno but without the timeout flag.

The pre-send budget also now resets after a hop that reaches the server. It is
meant to bound consecutive connect failures, not the lifetime of the call, and
without the reset an early run of blips permanently spent it, so a later blip
surfaced as a transport error while the status budget still had room. That is
the coupling the two counters were split apart to remove, in the one ordering
the earlier tests missed. Total work stays bounded, since every reset costs a
status attempt and those are capped.

Also corrects the SendWithAuthRetry comment, which still claimed the inner path
retried only 429/503/529.

Tests cover dial and proxyconnect timeouts as retryable and read/write timeouts
as not, a refused proxy CONNECT, and the interleaved pre-send/status/pre-send
sequence. Each fix fails its test when reverted.

euxaristiaandClaude Sonnet 5 97ef90d27a chore: remove code unreachable on every supported platform (#706)
* chore: remove code unreachable on every supported platform

The Security and code health job's advisory deadcode step reports 152
unreachable functions on main. Running the same check under GOOS=linux,
windows, and darwin shows 13 of those are false positives whose callers
live in windows build-tagged files, so only functions unreachable on all
three platforms are touched.

Functions with no references anywhere are deleted, including the
internal/reasoning package, which nothing imports. Functions that only
tests reference move into per-package export_test.go files so tests keep
their seams while the production binary sheds the code. Test call sites
of deleted convenience wrappers are ported to the live APIs (scoped tool
constructors, tools.DeferredSource, FinishReason checks).

Kept despite the report: cron.Store.Runs (only reader of runs.jsonl,
which production writes), and agenteval.TraceEventKeys and
MissingTraceEvents (used across packages by the trace contract test).

* docs(config): correct ValidateFile's errors.As claim

Message is a flattened string (.Error() already called on the parse

The dead-code pass removed the Emit methods but left Sink, NDJSONSink, and
TextSink exported with a contract nothing implements; remove the types with
their contract. Also remove the stray blank line at EOF of trace.go flagged
by gofmt, and update skills package docs and HOW_ZERO_WORKS.md to stop
directing callers to DiscoveryRoots/Duplicates, which are now test seams.

Co-Authored-By: Claude Fable 5 <[email protected]>

* chore: clean up remaining review nits on dead code removal

Replace a pointless fmt.Errorf(...%w...).Error() with fmt.Sprintf
using %v, since the wrapped error was discarded immediately anyway.
Remove a comment block that was duplicated verbatim.

* docs(skills): drop remaining references to test-only List/Get

Load and MergedSkills comments still named List/Get as production
entry points after they moved to export_test.go. Point callers at
Load and ListFromRoots instead.

* chore: remove now-unreferenced export_test.go seams

execSessionManager.len() and likelySandboxDenied/sandboxDenialKind had
no remaining callers after the sandbox unify-command-execution rebase;
the production code they wrapped for tests no longer exists.

d66a9dda69 feat(providers): add AI/ML API preset (rebased onto main) (#621)
* feat(providers): add AI/ML API preset

* fix(providers): relocate aimlapi preset and drop referral header

Addresses the two review asks on #402:

- Move the AI/ML API descriptor out of catalog slot #2 (it sat above the
  first-party OpenAI/Anthropic/Google entries) down next to openrouter in
  the aggregator cluster. Re-sync expectedCatalogIDs and the
  TransportOpenAICompat order-list to match.
- Drop the always-on X-AIMLAPI-Partner-ID / Integration-Repo /
  Integration-Version attribution headers. There's no partner arrangement
  behind the preset, so a non-overridable referral tag on every user's
  request isn't something to ship on a community preset. aimlapi now rides
  through plain CopyHeaders like every other provider. Removes
  HeadersForCatalog (it existed only for this special-case), reverts the
  factory and discovery call sites to CopyHeaders, and drops the header
  test. The factory/discovery tests now assert the endpoint, auth, and the
  user's own custom headers survive while no attribution header is sent.

* fix(providers): address CodeRabbit review on #621

- Document AIMLAPIID for docstring coverage.
- Apply providerio.CopyHeaders for Anthropic and Google provider paths,
  matching the OpenAI path introduced for aimlapi header isolation.

Vasanth T abe24bcb10 Add per-turn tracing and a turn-benchmark harness (Phase 0 baseline) (#700)
* Add per-turn tracing and a turn-benchmark harness (Phase 0 baseline)

Introduce an opt-in `internal/trace` package that attributes a run's wall
time to named spans — prompt build, provider connect/queue, generation,
tool queue/execution, permission wait, verification, compaction,
persistence — plus counters for model requests, tool calls, retries,
reconnects, compactions, completion nudges, acceptance checks, model
switches, and input/cached/output tokens. The recorder is nil-safe (a nil
*Recorder is a no-op), so every stamp site can call it unguarded; an
untraced run is byte-identical to today.

The recorder threads into agent.Run via a new `Options.Trace` field and a
single `trace.WithContext` assignment, so the shared providerio seam
(connect around client.Do, queue around OAuth resolve, first token at the
first non-keepalive SSE payload) reaches it through `trace.FromContext`
without any provider-interface change. All instrumentation is opt-in: when
`Options.Trace` is nil the hot path is untouched.

Headless `zero exec` gains `--trace <path>` (and `ZERO_TRACE=<path>`),
writing an agenteval-contract-compatible NDJSON trace (`-` for stderr).
The trace is pure observation; enabling it does not change behavior.

A new per-turn benchmark harness extends `internal/perfbench` (reusing the
existing TaskSet/NumericStats/subprocess runner shapes): `RunTurnBench`
aggregates per-span median/P95 across iterations, ranks the top three
controllable latency sources by share of attributed time, rolls up per
task class, and totals tokens/counts. A checked-in 42-task manifest across
seven classes (nav, edit, fix, refactor, longproc, longctx, parallel) and
local offline fixtures back it, and `make baseline` runs it against the
built `zero`, writing `internal/perfbench/reports/baseline.json`. The
report is machine-specific and regenerated, not hand-edited.

The manifest is JSON rather than YAML to avoid adding a dependency;
per-task verification targets the specific test (`go test -run <name>`)
so fix tasks are independent. Each task is a fresh `zero exec` process, so
iterations are cold-start samples; a warm in-process path is left for
follow-up.

Verified: `go build ./...`, `go vet ./...`, `gofmt -l` clean on touched
files; `go test -race` green for internal/trace, internal/agent,
internal/perfbench, and cmd/zero-perf-bench.

* test(trace): make TestAttributionRatio clock-independent

The test recorded two synthetic 10ms spans with no real delay and asserted
the attribution ratio stayed <= 1.0. On a precise clock (Linux/macOS CI) the
wall is microseconds while attributed is 20ms, so attributed/wall blows past
1.0 and the test failed — even though the ratio legitimately exceeds 1.0
when spans overlap (parallel tool execution). On Windows the coarse timer
masked it, so the failure only surfaced in CI.

Assert the contract instead: attributed is the deterministic sum of span
durations, and the ratio equals attributed/wall (0 when wall is zero). Add a
zero-wall case for the divide-by-zero guard.

* Address review feedback on the per-turn tracer + benchmark harness

Benchmark runner (internal/perfbench):
- A nonzero agent exit code no longer counts as Passed. The runner set
  VerifyErr but then fell through to outcome.Passed = true, so a crashed
  run could be recorded as a pass. Return before the verification block
  when VerifyErr is already set.
- A task now passes only when every iteration passes. The previous
  "any iteration passes" rule let a flaky fail hide behind one good run.
- Each invocation copies its workspace fixture to a fresh temp dir and
  runs the agent + verifier there, so mutating tasks (edit/fix/refactor)
  can't dirty the checked-in fixtures or bleed into the next iteration.
- Trace load failures (missing/malformed trace file) are surfaced as
  result warnings via a new TraceIssue field instead of being swallowed.

Tracer (internal/trace):
- Finish freezes the recorder: Counter, addSpan, and the first-event
  stamps are dropped after Finish returns, so a snapshot captures exactly
  one turn and late stamps can't mutate it.
- WriteText propagates the first write error instead of silently
  swallowing sink failures.

Provider seam (internal/providers/providerio):
- FirstTokenAt is stamped only after a payload is accepted as real model
  output, not before handle() decides to drop it as an error payload.

Agent loop (internal/agent):
- The compaction counter increments only when the history actually
  shrinks, in both the proactive and reactive paths — paid no-ops no
  longer inflate the compaction total.
- Document on Options.Trace that a fresh Recorder is required per Run.

CLI (internal/cli/exec):
- Finish the trace at the agent.Run boundary and defer only the
  serialization, so the snapshot covers exactly the turn.
- Reject --trace / ZERO_TRACE for spec-draft runs with a clear error
  instead of silently accepting and writing nothing.

Manifest + fixtures:
- Strengthen the edit verifiers: rename and value-bump tasks now assert
  the old symbol is gone, and the getter task greps the method signature.
- Add the missing testdata/edit fixture (10 edit tasks referenced a
  directory that was never committed, so the whole edit class errored
  out at run time).
- The manifest test now stats each fixture so a missing dir fails at
  load time instead of at every run.
- longproc benchmark keeps Process live across the loop; README code
  fence gets a language tag and documents the per-invocation fixture copy.
- Add tests for the tracing wrapper (nil vs wired recorder, OnUsage
  forwarding, token aggregation) and the frozen-recorder contract.

* Address review feedback: exclusive-time attribution + wired spans + fix-suite compile

Rewrite the trace attribution model so concurrent/nested spans no longer
double-count. Spans record wall intervals; the recorder derives a parent for
each by interval containment and computes exclusive time (duration minus the
union of its children). AttributedDuration sums only top-level spans; Coverage
is the union of intervals over wall, capped at 1, the honest ">=95%" metric.
Top-latency ranking uses exclusive time so shares sum to ~1 instead of being
inflated by overlapping provider_connect/generation and nested
permission_wait/tool_execution.

Wire the spans that were named but never stamped: verification around the
self-correct verify pass, and StampFirstVisibleEvent on the first forwarded
text event. Drop the tool_queue/process_wait/persistence constants that had no
stamps, and rename the misnamed near-noise prompt_build span to tool_partition.
Trim RequiredEventKeys to events a healthy short run actually emits; move
conditional phases (tools, permission, compaction, verification) to
OptionalEventKeys so a short trace does not false-fail.

Make ReadNDJSON fail loudly on a corrupt file: require a type:trace header,
error on span/counter lines that appear before it, and error when a header
yields no spans or counters.

Fix the blocking fix-suite compile error: Label's %d format verb on a string
tripped go test's vet before any fix task could verify. Make it a runtime
wrong-prefix bug ("admin-" vs "user-") that still type-checks, so each fix
task is independent again.

Manifest: correct refactor-04's stats.go to main.go, reword fix-07 to the
wrong-prefix bug, add a latency-only description (read-only tasks carry no
verification oracle by design), and frame the report README on exclusive time
and coverage.

Tests updated for the occurrence/exclusive/coverage model; trace, perfbench,
and agent green under -race.

* Fix exclusive-time round-trip, identical-interval nesting, and empty-trace parse

Three correctness bugs in the attribution model found by an adversarial review
of the prior commit, all undermining the no-double-count guarantee:

1. exclusive_ms:0 was overwritten with the inclusive Duration on re-parse. A
   parent whose children tile its interval legitimately has exclusive time 0;
   WriteNDJSON emits exclusive_ms:0, but ReadNDJSON's "<= 0 means missing"
   fallback turned that back into the full duration, so every re-parsed trace
   re-introduced the double-counting the model exists to prevent (the benchmark
   harness, which ranks re-parsed traces, inherits it). Gate the fallback on
   key ABSENCE, so a written 0 is preserved.

2. deriveNesting formed a 2-cycle for two spans with identical [start, end]
   intervals: the symmetric containment check made each parent the other,
   dropping both from top-level and zeroing AttributedDuration. Break the tie
   deterministically — strict containment is an unambiguous parent; for
   identical intervals, only the lower-indexed span may parent the other, so
   one stays top-level.

3. ReadNDJSON returned a valid empty TurnTrace for empty/blank-only input, so a
   run that crashed before emitting a trace (or where --trace was not honored)
   masqueraded as a clean zero-attribution sample. Empty input now errors, so
   the harness records a TraceIssue.

Also: decode counters via json.Number so int64 values above 2^53 round-trip
exactly instead of losing precision through float64; and drop the harness's
own "exclusive <= 0 -> Duration" ranking fallback, which was the same
double-count on the re-parsed path. Added regression tests covering the
zero-exclusive round-trip, the identical-interval nesting, empty-input
rejection, and counter precision.

* perf(turn-bench): split pass/fail into oracle tiers so the pass rate can't be misread as correctness

The turn benchmark counted any exit-0 task as passed, including the 24
read-only tasks (nav/longproc/longctx/parallel) that carry no verification
oracle — so the JSON tasksPassed / "N/M passed" headline could read as a
correctness verdict it never was. Split pass/fail into three oracle tiers:

- correctness (edit grep + fix go test): the only pass rate that can move
  with model quality (tasksVerified / tasksPassed / correctnessPassRate)
- build-only (refactor go build): a non-positive oracle, reported as
  buildPassRate and excluded from correctnessPassRate; the manifest declares
  buildOnlyClasses: ["refactor"]
- latency-only (no oracle): counted in latencyOnlyTasks, never in any pass
  rate

NewTurnExecRunner no longer sets Passed=true for tasks with no
verificationCommand, and the summary headline names each tier explicitly so
an exit-0 read-only run cannot inflate a correctness number. Bumps
TurnSchemaVersion to 2. Class breakdown and tier contract documented in
internal/perfbench/MANIFEST.md and reports/README.md.

Also install the trace first-token/visible-event forwarding handlers in
agent.Run whenever options.Trace is set, not only when a UI OnText /
OnReasoning callback is set, so a headless traced run (zero exec --trace)
still captures FirstTokenAt. forwardedVisibleText stays tied to the user
callback so stall-retry semantics are unchanged. Adds a regression
assertion to the existing traced-run test.

* Address CodeRabbit review on 2bfb3406: omitempty + crash visibility

Three findings from CodeRabbit's review of the 3-tier pass-rate fix:

- BuildPassRate dropped its omitempty so an explicit 0.0 (all refactor
  tasks fail to compile) is no longer indistinguishable from 'no build
  tasks ran' in the JSON. Matches CorrectnessPassRate's always-serialize
  behavior, which is the whole point of the tier split: the report
  cannot be misread.
- A crashed sample (outcome.Err) now emits a Warning mirroring the
  TraceIssue path, so a run that died every iteration can't look like a
  normal benchmark with fewer measurements instead of a failure.
- cmd.Run()'s returned error is preserved on the no-run_end path: when
  stderr is empty and Run failed (binary missing, exec permission
  denied), the actual OS error is reported instead of collapsing to the
  generic 'missing terminal run_end event'.

go build/vet/gofmt clean; go test -race green for perfbench/agent/trace.

* Address CodeRabbit re-review: anti-averaging README + fixture-isolation test

Re-review at d0615249 asked for the pass-rate contract to be loud to
downstream consumers and for the fixture-isolation property to be asserted,
not just read from code.

- reports/README.md gains a prominent 'do not average the tier pass rates /
  do not report a single pass rate' warning. The schema offers no headline
  pass rate on purpose; a consumer must name the tier it is reporting. This
  is the durability fix for the misread the tier split exists to prevent.
- turn_bench_test.go gains TestCopyFixtureIsolatesSourceFromMutation: copies
  a fixture, mutates the copy, and asserts the source is byte-identical
  (and that a file added to the copy never appears in the source). Proves the
  'fixtures stay clean across runs' property without needing the binary.

Items the re-review also raised that were already satisfied: the
oracle-presence-over-declared-list precedence is documented on the
BuildOnlyClasses field (taskbench.go), and the PR body already says
'48-task manifest'. The Share->exclusiveShare rename is tracked in #701.

go build/vet/gofmt clean; go test -race green for perfbench.

KRATOSandKRATOS 1af58828eb fix(openai): omit prompt_cache_key for openai-compatible providers (#636)
Interactive TUI always has a session ID, so every completion request
forwarded OpenAI's prompt_cache_key. Strict openai-compatible gateways
(e.g. NVIDIA NIM) reject unknown fields with a 400, while plain zero
exec usually has no session and omits the field.

Disable prompt_cache_key for ProviderKindOpenAICompatible; keep it for
official OpenAI. ZERO_DISABLE_PROMPT_CACHE_KEY remains a global kill
switch.

* Fix OpenGateway credential lookup, stream error code mapping, and model catalog

* fix(providers): map semantic OpenAI stream error codes, not just numeric

Addresses jatmn's review (following up on CodeRabbit's original request):
the streamed error classifier only recognized numeric codes ("429", 401,
403 as string/float64/int), so semantic string codes OpenAI-compatible
providers commonly send instead (rate_limit_exceeded, insufficient_quota,
invalid_api_key) fell back to a generic 500 and lost their rate-limit/auth
classification.

Unified the numeric and semantic mappings into one
openAIStreamErrorStatusByCode table so both forms of the same condition
classify identically. insufficient_quota maps to 429, matching OpenAI's
own API behavior for quota-exceeded errors.

Added TestStreamCompletionClassifiesStreamErrorCode covering both forms.

* test(providermodelcatalog): cover the new gitlawb-opengateway catalog IDs

Addresses jatmn's review (completing CodeRabbit's original request):
TestModelsAreProviderScoped only asserted mimo-v2.5-pro and tencent/hy3
for gitlawb-opengateway, missing the other newly curated IDs added in
this PR (xiaomi/mimo-v2.5-pro, minimax/minimax-m3, qwen/qwen3.7-max,
google/gemini-3.1-flash-lite, z-ai/glm-5.2,
nvidia/nemotron-3-ultra-550b-a55b:free). A typo or accidental removal
in any of them would not have failed a test.

* test: cover the last catalog ID and probeProviderHealth's stored-key wrap

Addresses jatmn's second follow-up review on PR #580:
- TestModelsAreProviderScoped still missed xiaomi/mimo-v2.5 (distinct
  from xiaomi/mimo-v2.5-pro) among the newly curated gitlawb-opengateway
  catalog entries.
- fillAppDeps wraps probeProviderHealth the same way it wraps
  newProvider, applying the stored credential-store key before
  delegating, but only newProvider's wrap had a regression test
  (TestFillAppDepsWrapsNewProviderWithStoredKey). Added the parallel
  TestFillAppDepsWrapsProbeProviderHealthWithStoredKey so the health-check
  path used by `zero providers check --connectivity`, `zero doctor
  --connectivity`, and the TUI doctor panel can't silently regress back
  to keyless probes.

Kevin Codex 87e7e69afd feat(openai): forward prompt_cache_key for server-side prefix cache routing (#515)
* feat(openai): forward prompt_cache_key for server-side prefix cache routing

Send the session ID as OpenAI's prompt_cache_key on every completion
request so consecutive turns route to a backend replica that already
holds the conversation prefix in its prompt cache, instead of re-billing
the full ~11k-token system+tools prefix each turn on OpenAI-compatible
endpoints (which get no cache_control breakpoints, unlike Anthropic).

Keyless requests serialize byte-identically to before, and
ZERO_DISABLE_PROMPT_CACHE_KEY=1 suppresses the field for strict
endpoints that reject unknown parameters. The Codex (Responses API)
flavor is deliberately untouched: the ChatGPT backend is a separate,
stricter surface.

* fix(openai): parse prompt-cache-key kill switch as a boolean flag

ZERO_DISABLE_PROMPT_CACHE_KEY=0 or =false previously disabled forwarding
because any non-empty value tripped the check. Parse it the same way
ZERO_FORMAT_ON_WRITE parses boolean flags, so explicitly-falsy values
are a no-op and only truthy values flip the toggle.

Kevin Codex 3c81fea228 feat: agent quality, caching, retry, and tooling upgrades (#506)
* feat: agent quality, caching, retry, and tooling upgrades

Ten self-contained improvements to the core agent engine and tools:

- edit_file: fuzzy fallback matching (7-strategy cascade with uniqueness
  protection and a disproportion guard) when old_string does not match
  byte-for-byte; exact match remains the fast path
- edit_file/write_file: inline error-severity LSP diagnostics in tool
  output so the model sees a break it introduced in the same turn
- lsp: expand server registry from 4 to 28 languages; doctor grades only
  tier-1 servers and lists the long tail informationally
- agent: consecutive read-only tool calls execute concurrently (bounded
  at 8), consumed in original order, never spanning a mutating call
- anthropic: cache_control breakpoints on the last two conversation
  messages so the transcript prefix stays a prompt-cache hit
- providerio: retry schedule raised to 6 attempts with exponential
  2s-30s backoff when the server sends no Retry-After
- tools: truncated exec/bash output spills to a redacted temp file
  referenced in the truncation notice; bash output (previously
  unbounded) now shares exec_command's token budget
- web_fetch: dependency-free HTML-to-markdown conversion (format:
  auto|raw|markdown) and larger limits (256KiB default, 2MiB max, 30s)
- modelregistry: live models.dev overlay refreshes context limits and
  base pricing from a TTL-cached fetch; opt-in at the CLI entrypoint
- tools: opt-in format-on-write (ZERO_FORMAT_ON_WRITE=1) runs standard
  formatters across 27 extensions, ordered before the file-tracker
  re-baseline so conflict detection is preserved

* fix: address PR review feedback on fuzzy edits, diagnostics, spill

- edit_file: adapt the replacement to the fuzzy-resolved span — when the
  span is a uniformly deeper-indented copy of old_string (line-trimmed /
  indentation-flexible matches), the same indentation delta is applied to
  new_string, and a span ending in a bare CR keeps its CR so CRLF files
  never gain a mixed line ending; block-anchor matches with drifted
  interiors are deliberately left untouched
- diagnostics: render workspace-relative paths in inline post-edit
  diagnostics (base name outside the workspace) so absolute paths never
  leak the local username or directory layout into the model prompt or
  session transcript
- spill: harden the spill directory for shared temp dirs — per-uid name,
  reject symlinked or non-directory paths (MkdirAll follows symlinks),
  and on Unix require current-user ownership
- bash: the branch's output cap and truncation-flag threading are
  superseded by main's capture-time bounding (boundedBuffer +
  budgetBashCapture), which already sets Result.Truncated; this rebase
  adopts that design and keeps spill-to-disk on exec_command, where the
  full output is still buffered and a spill is genuinely complete

* fix: address review round 2 — permission-event race, fuzzy ambiguity, spill reachability

- agent: serialize OnPermission behind the same mutex as
  OnPermissionRequest in the parallel read batch. buildPermissionEvent
  fires for batched reads with a non-trivial sandbox decision (e.g. a
  grant-matched extra root), and front-end handlers append to shared
  session-recording state without their own locking — two batched reads
  emitting concurrently was a data race the pre-batch serial loop never
  allowed.
- edit_file: reject two or more DISTINCT candidate spans from one fuzzy
  strategy as ambiguous instead of silently editing the first. Duplicate
  blocks at different indentation each resolve to a unique literal, so
  the previous occurrence-uniqueness check passed and wrote the wrong
  span. A single candidate occurring at multiple positions still
  cascades to stricter strategies as before.
- tools: make spill files actually reachable by the recovery path the
  truncation notice advertises — resolveScopedReadPath now recognizes
  files inside the per-uid spill dir (containment verified after symlink
  resolution, so a planted link cannot smuggle an out-of-scope file
  through the gate); read_file/grep can follow the notice instead of
  re-running the command.

* fix: surface competing block-anchor spans; make write-barrier test observe cross-probe order

- edit_file: blockAnchorReplacer now returns every span clearing the
  similarity threshold (best first) instead of silently picking the
  single most-similar block. Hiding competitors from the cascade's
  distinct-candidate check could edit the wrong block when two blocks
  share anchors and both interiors are plausible; one clear winner still
  resolves, two plausible blocks now report ambiguity (covered by a
  two-block test that asserts the file is untouched).
- agent tests: the parallel write-barrier test now records both probes
  into one mutex-guarded shared log and asserts the cross-probe ordering
  it always claimed to (write starts after the first read batch ends;
  second read batch starts after the write ends). The previous version
  only compared indices within the read probe's own log, which a
  regression letting the write overlap a batch could still pass; the
  stray no-op mutex assignment is gone.

* feat(tui): actionable hints on provider/model errors

Classify a failed turn's provider error into auth / rate-limit /
connectivity / model-not-found / context-overflow and render a one-line
next step below the red error row, instead of dumping an identical raw
blob for every failure mode.

The classifier lives in a new internal/errhint package so both the TUI
error row and the CLI exec path can share it (TUIHint references slash
commands, CLIHint references zero subcommands). Classification is a
conservative string heuristic keyed off providerio.ClassifiedError's
prefixes plus lower-level DNS/TLS/timeout/context-length signatures,
since the numeric HTTP status is gone by the time the error reaches a UI
surface.

* feat(tools): budget bash output with head+tail truncation

bash was the one tool that returned command output with no byte cap —
'cat large.log' or a verbose test run could dump megabytes into context
and force compaction, while every other read/search tool already applies
a budget.

Cap stdout and stderr at 96KB each, keeping the head and tail of an
oversized stream (build/test failures usually land at the tail) and
dropping the middle behind a marker that points at redirect-to-file +
read_file. Record raw_bytes/emitted_bytes/estimated_tokens/truncated in
Meta like the other tools. Sandbox-denial and shell-issue detection still
run on the full raw output before budgeting.

* fix(gemini): retry 401 with refreshed OAuth token

The Gemini provider used providerio.SendWithRetry (429/503/529 only),
so an expired OAuth token surfaced as a terminal 'API key not valid'
auth error while OpenAI and Anthropic silently recovered via
SendWithAuthRetry's force-refresh-and-replay on 401.

Plumb OAuthResolver through gemini.Options/Provider and the factory
(exactly as the other two providers already do) and switch the stream
send to SendWithAuthRetry. With a nil resolver (API-key users) behavior
is unchanged.

* fix(errhint): gate classification on provider-origin marker

Address CodeRabbit review on #1: agentResponseMsg.err can also carry
local failures (a tool's 'permission denied', a 'file does not exist',
a config error), and broad substrings would have attached a bogus
/provider or /model hint to those.

Classify now returns Unknown unless the message carries a provider marker
the provider layer always attaches (auth error: / rate limit error: /
provider error: / provider request error: / provider stream error:).
Local errors never draw a provider hint; provider errors sub-classify as
before. Added local-failure test cases proving they stay Unknown.

* feat(cli): actionable hint on text-mode exec provider errors

zero exec printed provider failures as a bare '[zero] <raw error>' with
no next step. Append a one-line hint (reusing the shared errhint
classifier) for recognized provider failures — 'run `zero auth`',
'run `zero doctor`', etc. The provider-origin gate means non-provider
codes (sandbox_error, mcp_error) and JSON/stream-json output are
untouched.

* fix(tools): set Result.Truncated for budgeted bash output

Address CodeRabbit review on #3: budgetBashOutput recorded truncation in
meta["truncated"] but never set the Result.Truncated struct field, so
consumers reading the struct (like glob/web_fetch/read_minified do) would
miss truncated bash results. Return the bool from budgetBashOutput and
set Result.Truncated on every return path.

* perf(tui): reuse one LSP manager across prompts

runAgentWithOptions built a fresh lsp.NewManager per run and shut it down
when the run returned, so gopls (and every other language server)
cold-started on the first edit of every turn — 200ms-2s of latency the
manager's own design (long-lived, reused servers) exists to avoid.

Build one manager per session in newModel (cheap: servers start lazily on
first Check) and reuse it across runs; the SelfCorrector still gets a
fresh checker wrapping the shared manager each run. Torn down with a
short deadline in quit(). Runs fall back to a per-run manager when the
session manager is absent (cwd unknown, or a directly-built test model).

* perf(tui): accumulate streamingText as []byte (O(1) append)

m.streamingText += msg.delta was O(len) per delta -> O(n²) across a long
generation (a 10k-token code gen allocates hundreds of MB of intermediate
strings and the UI gets progressively laggier). Accumulate into a []byte
with append (O(1) amortized) and read via streamingTextString().

A []byte rather than strings.Builder because the TUI model is copied by
value on every Update, which would trip strings.Builder's copy check;
[]byte is nil-safe and copies cleanly like the other slice fields.

* perf(tui): coalesce streamed text deltas to one frame

Every OnText delta was its own tea.Msg, so a fast provider (100+ tok/s)
drove 100+ full Update->View cycles per second, each re-parsing the
growing markdown — visible stutter over SSH and wasted CPU.

Batch agentTextMsg deltas at the runtime sink over a ~16ms frame and
forward them as a single message, decoupling render rate from token rate.
Any non-text message flushes pending text first so ordering with
tool-call / reasoning / row messages is preserved; the final
agentResponseMsg (a tea.Cmd return, not a sink message) is safe because
the model already drops deltas for an inactive runID.

* fix(agent): raise tool-failure stop threshold 4->6

guardrails.go halted a run after 4 consecutive same-error tool failures.
A corrective hint fires at 2, and a model iterating on a genuinely tricky
edit can legitimately fail a couple more times after the hint while
converging — stopping at 4 cut those runs short. Raise to 6; the streak
still resets the instant the tool succeeds or hits a different error, so
only true same-error loops are affected.

* fix(agent): more reconnect retries with jitter; narrow to transport errors

#19: bump maxStreamReconnects 2->4 and add up-to-50% jitter on the
exponential backoff (capped at 8s), so a multi-second network blip is
ridden out instead of killing the run on a 2s hiccup, and concurrent runs
(swarms, cron fleets) don't reconnect in lockstep.

#34: drop the '502'/'503' substring matches from shouldReconnect. 503
already exhausted providerio.SendWithRetry (retrying here is a redundant
double-retry) and 502 is non-idempotent by providerio's rule (the POST
may have been processed). Only genuine transport failures — where no
response was received — reconnect now.

* fix(agent): reduce stall retries 2->1 to bound stuck-session time

A no-output stream stall is detected only after the full stream idle
timeout (~5min) elapses, and each retry can idle again — so 2 retries
left an interactive session frozen for ~15min. Drop to 1 retry: keeps the
common single-hiccup recovery while bounding the worst case to ~2x the
idle timeout.

* fix(tui): serialize coalescer forwarding to preserve message order

Address CodeRabbit review on #7: flush() and the run-switch path drained
the text buffer under c.mu but called forward() after releasing it, so a
timer-fired text flush could race a concurrent non-text send() and land
after the tool-call/reasoning message it should precede.

Hold c.mu across drain AND forward (drainAndForwardLocked), so whoever
holds the lock delivers atomically and the other caller blocks until it
is done — text can never overtake a following non-text message. Added a
concurrency stress test (timer racing an inline send) that passes under
-race.

* feat(tui): accept /compact now

Bare /compact already triggers compaction, but /compact now — what users
reach for when the context gauge climbs — hit the usage-error branch.
Accept the 'now' keyword and advertise it in the command usage.

* feat(tui): add /retry, /edit, /copy, /export commands

/retry resends the last prompt; /edit recalls it into the composer to
tweak and resend — both read a new lastPrompt field captured verbatim
(pre-expansion) in launchPrompt. /copy puts the last answer on the
clipboard via the existing copy machinery; /export writes a plain
role-prefixed transcript to a file (timestamped default, or a given
path). Real gaps for SSH users with no mouse select.

* feat(tools): separator-insensitive tool_search matching

tool_search ranked deferred tools by exact substring, so a model that
typed 'webfetch' (dropping the underscore) matched nothing and looped.
Add a separator-squashing fallback ('web_fetch' -> 'webfetch') scored
below an exact substring match, so precise queries still rank first.

* feat(tools): signal ask_user dismissal distinctly from a blank field

Empty answers all rendered as '(no answer provided)', so the model
couldn't tell a wholesale dismissal (user closed the prompt without
answering anything) from one field left blank amid real answers — and
might invent a default. FormatAskUserAnswers now flags a full dismissal
up front as a skip and marks individual empties '(left blank)' vs
'(skipped)'.

* feat(tui): fuzzy ranking in model/session pickers

The pickers filtered by flat strings.Contains with no ranking, so
finding 'sonnet 4.5' among 50+ models meant an exact prefix or scrolling.
Rank matches (exact < prefix < contains < subsequence, reusing
fuzzySubsequenceGap) so the closest match lands on top, and 'snt45' now
matches 'Sonnet 4.5'. Groups stay contiguous — ordered by their best
match, never split — so the grouped model picker still renders one header
per provider. Covers both /model and /resume (shared commandPicker).

* perf(agent): cache per-tool schema render across turns

partitionTools re-ran the recursive schema->map conversion
(schemaToRuntimeMap) for every tool on every turn — redundant, since a
tool's advertised name/description/schema is stable for the run. Add a
per-run definition cache keyed by tool name (nil-safe; the plain
partitionTools entrypoint and tests pass nil for fresh renders).

The partitioning itself (visibility, deferral, ordering) still recomputes
every turn — it must, because a tool's deferred state can flip mid-run
(swarm tools un-defer once a swarm is active). Only the expensive schema
render is memoized. tool_search is excluded by its callers (dynamic
description) so it never poisons the cache.

* perf(agent): calibrate compaction estimate against real prompt tokens

The byte/4 heuristic (ApproxTextTokens) over-counts code-heavy content
~15-20%, so with triggerRatio=0.7 compaction fired at ~60% of true
capacity — premature summarizer calls that degrade quality. Each turn now
folds (rawEstimate, provider InputTokens) into an EMA calibration ratio,
clamped per-sample to a sane band; maybeCompact and the reactive path
scale their estimates by it. Turn 1 uses the raw estimate (no data yet);
later turns compact near real capacity.

* style: gofmt the new agent test files

The CI gofmt check flagged the #22/#25 test files (struct-field and
switch alignment). No behavior change.

* feat(agent): turn-based plan staleness reminder

The stale-plan nudge only fired after 10 tool calls since the last
update_plan, so a plan that drifts stale across many low-tool-call turns
(one call per turn) took many turns to catch — the 'plan set turn 1 stays
pending forever' case. Add a turn-count complement: after
stalePlanTurnThreshold (8) turns without an update AND with items still
pending, fire the same one-shot reminder. Gated on pending items so a
fully-completed plan is never nagged; the existing tool-call trigger is
unchanged. (The roadmap's fuzzy 'tool calls unrelated to plan items'
relevance match is deliberately omitted — too false-positive-prone.)

* feat(agent): preserve recent-edits summary across compaction

Compaction preserved the plan, loaded skills, tool schemas, and project
instructions, but not file edits — so after the editing turns were elided
the model knew it had changed a file only vaguely, and would re-read to
rediscover its own footprint. Extract write_file/edit_file targets from
the elided middle with a one-line note from each tool result, merge them
across repeated compactions (newer note per path wins), and carry them in
the preserved-state JSON (capped at 20 paths / 160 bytes per note).

* feat(tui): workspace-scoped /resume + fewer event reads

/resume listed sessions from every project globally, and read the full
event file for each of them to test for resumable content. Filter the
picker (and /resume latest) by the current workspace Cwd, checked BEFORE
the per-session read so a large global history no longer pays N full file
reads to build one workspace's list; also skip zero-event sessions via
metadata without any read. Sessions with no recorded Cwd (older runs) and
an unknown current workspace stay visible so nothing is hidden that can't
be confidently placed. Explicit /resume <id> still resolves any session.

* feat(tui): warn on model switch that drops staged images

Staged images were silently dropped at submit when the active model had
no vision support — the user only learned after sending. Chips already
render above the composer (renderAttachmentChips); add an immediate amber
warning line to the /model switch status (both same-provider and
cross-provider paths) when images are staged and the newly selected model
can't accept them, so the drop is surfaced at switch time.

* feat(tui): inline recovery affordance on setup errors

A first-run setup error rendered as a bare red 'error: <text>' with no
pointer to the fix. Append a faint, stage-tailored recovery line (edit
the endpoint/name/key above then Enter, or pick another model) that names
only keys the stage's footer confirms, so the guidance is always accurate.
Empty for stages whose footer already makes recovery obvious.

* fix: address CodeRabbit review (5 findings)

- loop.go: recompute the compaction calibration estimate at calibration
  time, not request-build time, so a reactive-compaction reissue that
  shrinks the request feeds the EMA the sample that actually completed.
- errhint: match bare HTTP status codes (401/403/429/529) only at digit
  boundaries, so an incidental number ('4290ms', 'id 14015') isn't
  mis-bucketed as auth/rate-limit.
- bash: drop the stray unmatched ']' in the output-truncation marker.
- tui /retry: apply the same exiting/compactInFlight guards commandPrompt
  has, so a retry can't race compactResultMsg's rewrite of session state.
- tui /export: write the transcript 0o600 (it may contain echoed
  secrets), not world/group-readable 0o644.

* test(tui): skip export file-mode assertion on Windows

os.WriteFile ignores Unix permission bits on Windows and Stat reports
0666, so the 0o600 assertion failed there. The production 0o600 is
honored on Linux/macOS (where it matters); guard the check with
runtime.GOOS so Windows smoke passes.

* fix(tui): align /resume latest filters + case-insensitive workspace match on Windows

Address CodeRabbit review on #21:
- latestResumableInWorkspace now applies the SAME filters as the picker
  (skip zero-event metadata and empty/failed runs), so /resume latest
  can't land on a session the picker intentionally hides.
- sessionMatchesWorkspace compares paths case-insensitively on Windows
  (its filesystem is), so the same workspace spelled with different casing
  no longer hides resumable sessions; other platforms stay case-sensitive.

* fix(tui): /retry resends the last prompt's image/PDF attachments

/retry relaunched only lastPrompt's text, but launchPrompt clears the
pending image/document queues once a turn is sent. A vision- or PDF-backed
prompt that failed would silently retry as text-only and answer a different
task. Snapshot the consumed attachments at launch and re-stage them on
/retry so launchPrompt rebuilds an identical request (document preamble,
images, and the submit-time vision re-check). startNewSession drops the
snapshot so a post-/new /retry cannot leak the previous session's
attachments. Also correct the OAuthResolver factory comment, which omitted
the Gemini provider it is now passed to.

* fix: address jatmn review (reconnect 5xx, /edit attachments, edit-cap, coalescer test)

- reconnect: exclude HTTP 5xx (500/502/503/504) before the transport
  substring match so "504 Gateway Timeout" no longer slips through on the
  generic "timeout" needle. A gateway timeout is non-idempotent — the
  completion POST may already have reached the model — so replaying the
  connect risked duplicate billable work. Reuses a digit-boundary status
  matcher exported from errhint (HasStatusCode). Test asserts 504/500 stay
  non-reconnectable.

- tui /edit: re-stage the remembered image/PDF snapshot alongside the
  recalled prompt text, mirroring the /retry fix — editing a vision- or
  document-backed prompt no longer silently resends a text-only version.

- compaction recent-edits: order edits by LAST edit, not first, and move a
  re-touched path to the newest position on merge, so the maxRecentEdits
  tail cap keeps the file the model most recently edited instead of dropping
  it. Adds mergeRecentEdits (edit-specific) and a capped-list regression.

- coalescer test: inject the frame timer via afterFunc so
  TestCoalescerBatchesDeltas proves buffering deterministically instead of
  racing the real 16ms wall-clock timer.

* fix(tools): bound bash output capture in memory, not just model-visible text

Previously stdout/stderr streamed into unbounded bytes.Buffers and were only
truncated to the 96 KiB budget AFTER the command finished, so a runaway command
(cat huge.log, yes) could grow Zero's memory until it stalled or OOMed before
budgetBashOutput ever ran. Replace the capture with boundedBuffer, an io.Writer
that keeps only the head+tail each stream will surface and discards the middle as
it arrives, while counting the true total for the truncation marker. Memory is now
bounded to ~head+2×tail per stream regardless of output size.

truncateHeadTail is refactored onto a total-aware core so the string path (and its
tests) are unchanged, and budgetBashCapture reports the true raw_bytes even though
only a bounded slice was held. Adds boundedBuffer/capture unit tests and an
end-to-end test that streams ~5× the budget and asserts bounded emission with an
accurate raw_bytes.

KRATOS 39e7100674 fix(gemini): strip unsupported JSON Schema fields from tool declarations (#374)
Every exec against the Google/Gemini provider failed: Zero emits tool
parameter schemas in OpenAI's JSON Schema dialect, which always includes
`additionalProperties` (schemaToRuntimeMap writes it unconditionally).
Google's functionDeclarations schema doesn't recognize that keyword and
400s the whole request — "Unknown name \"additionalProperties\" …
Cannot find field" — so no tool-using call ever reached the model.

Sanitize tool parameters in the Gemini mapper (only there — the field is
valid and wanted for OpenAI strict mode and harmless for Anthropic):

- sanitizeGeminiSchema keeps only the keywords Gemini's Schema type
  supports (type, description, enum, properties, required, items, anyOf,
  default, nullable, format, and the min/max/length constraints) via an
  allowlist, so any future OpenAI-ism or MCP-supplied field can't leak.
- Recurses through properties, items, and anyOf so nested schemas are
  cleaned at every depth, not just the top level.

Tests: a unit test on the sanitizer (nesting, legit fields preserved,
nil-safe) and an end-to-end test asserting the outgoing request body's
functionDeclarations[].parameters carry no additionalProperties while the
real schema survives. Bypassing the sanitizer reproduces the reported
payload, so the coverage is red-green.

Fixes #373

KRATOS 6e0a665118 fix(auth): propagate credentials to every provider-build surface and pin children to the live provider (#366)
* fix(auth): propagate credentials to every provider-build surface and pin children to the live provider

Sub-agents, swarm members, ACP sessions, and mid-run escalation switches
could build providers without the credentials the parent was running with.
This consolidates credential resolution so every surface gets the same auth:

- Wrap deps.newProvider once in fillAppDeps to fold the stored API key in
  centrally; ACP, exec escalation, and buildProvider no longer patch it
  per call site (an apiKeyStored profile previously went out keyless on
  those paths and 401'd).
- Export ZERO_PROVIDER at startup (buildProvider) and keep exporting on
  every runtime switch (wizard, onboarding, /model, /provider), so spawned
  children resolve the parent's live provider instead of whatever another
  process last persisted to config.json. Injected via appDeps so tests
  never mutate the process environment.
- Share one OAuth login selection end to end: ProviderProfile.
  OAuthLoginCandidates (name, then catalog-ID fallback; nothing for a
  profile with its own configured credential) + oauth.FirstStored resolve
  the login ONCE, and the bound store key is threaded through
  providers.Options.OAuthLoginKey so the Codex account-id header always
  reads the same login that issued the bearer token. A renamed profile
  (name != catalog ID) now finds its login; an explicit API key is never
  silently overridden by a same-name or catalog-shared OAuth login.
- Export ProviderProfile.HasConfiguredCredential as the single "profile is
  key-authed" predicate (cli/tui/config previously had three copies).
- applyProviderWizard commits live state (provider, profile, name, env
  export) only after BOTH the build and the config persist succeed, so a
  persist failure no longer leaves the chat running on a provider the
  status line and children disagree with.

Covered by red-green tests for each path: stored-key wrap, escalation
switch, catalog-ID fallback (incl. case-variant names), explicit-key
protection, same-login account selection, wizard persist-failure rollback,
onboarding/startup env export.

* test: isolate OAuth/config test storage and fix the flaky MCP response-id test

Review + CI fixes, all test-only:

- factory/cli OAuth tests: pin ZERO_OAUTH_STORAGE=file next to the temp
  ZERO_OAUTH_TOKENS_PATH — an inherited "keyring" value sends NewStore to
  the OS keychain and ignores the temp path entirely, so the tests could
  read (or clobber) the developer's real logins. newOAuthStoreForTest now
  owns both pins so a future call site can't forget them.
- TestApplyProviderWizardExportsActiveProviderEnv: point m.userConfigPath
  at a temp config and stub newProvider, so the SUCCESS path exercises the
  full build+persist+commit sequence in isolation (the default empty path
  silently skipped persist; a changed default must never reach the real
  user config).
- TestClientRequestWaitsForMatchingResponseID (ubuntu smoke flake): the
  responses were pre-loaded into a bytes.Buffer, so the client's reader
  goroutine could consume the matching response — and hit EOF — before
  request() registered its pending id, failing with "request() error =
  EOF" on fast runners. The fake server now sits on pipes and responds
  only after reading the outgoing request, matching production ordering;
  survives -race -count=50.

KRATOS 02f0c0929b fix: cut the content-stall dead-wait and auto-retry a mid-tool-call stall (#362)
* fix: cut the content-stall dead-wait and auto-retry a mid-tool-call stall

Root-caused (via a verified multi-agent audit) the chatgpt/gpt-5.5 "stuck"
reports: the ChatGPT Codex backend pauses real generation mid-stream on
large single tool-call outputs (a ~1000-line write_file) while continuing
SSE keep-alive heartbeats. That is an upstream limitation, not a Zero bug
or a connection-pooling issue (the darwin DisableKeepAlives fix is applied
and confirmed not the cause). Zero already detected it, but two UX gaps
made it feel like a hang:

1. Faster abort. The content-stall watchdog fired at idle*2 = 10 minutes.
   A heartbeat-pause stall on gpt-5.x rarely recovers, so 10 minutes of a
   frozen token counter was a terrible wait for a doomed turn. Replaced the
   StreamContentStallFactor=2 const with ContentStallTimeout(idle)=idle*1.2
   (6 minutes at the default). It still only ever fires on a TRUE zero-output
   freeze — any real data line resets it — so healthy slow-reasoning runs are
   unaffected. Scales with ZERO_STREAM_IDLE_TIMEOUT; returns 0 (disabled)
   when idle is disabled.

2. Auto-retry the actual stall. The existing stall-retry only fired when
   NOTHING had been forwarded — so the common case (model streamed transient
   reasoning + began the big write_file, then froze mid-arguments) was NOT
   retried, because the incomplete tool call is collected and transient
   output was forwarded. Relaxed the gate to retry when no visible PROSE was
   shown (forwardedVisibleText, marked only by OnText) and no final text was
   collected — dropping the len(ToolCalls)==0 exclusion, since an incomplete
   tool call from a timed-out stream is never executed (the turn returns on
   the error before dispatch) and never appended to messages, so the retry
   re-sends clean context with no duplication. A visible
   "[no output — model stalled; retrying N/max]" notice fires per attempt.
   Forwarded prose still blocks the retry (it would duplicate answer text).

Verified: full -race suite green; a 4-dimension root-cause audit and a
3-dimension adversarial review of this diff both passed with no confirmed
defects. New tests: TestRunRetriesStallAfterIncompleteToolCall (the exact
gpt-5.x case), TestRunRetriesStallAfterOnlyReasoning; preserved
TestRunDoesNotRetryStallAfterPartialOutput (prose still blocks retry).

* fix(providerio): make ContentStallTimeout overflow-safe

Address PR #362 review: idleTimeout*6/5 could overflow int64 for a
pathologically large ZERO_STREAM_IDLE_TIMEOUT and wrap to a NEGATIVE
duration, which would arm the content-stall timer to fire immediately and
abort every stream. Compute 1.2× as idle + idle/5 with a clamp to the max
duration on overflow (which just means "effectively no content watchdog",
the sane result for an absurd idle timeout). The normal 1.2× values are
unchanged (5m->6m, 30s->36s, 100ms->120ms).

New test: TestContentStallTimeout covers the scaled values, the
zero/disabled case, and the MaxInt64 overflow guard.

KRATOS 85273ea72d fix(providerio): disable HTTP keep-alive reuse on macOS to defeat degraded-connection stalls (#360)
This codebase already has a documented, previously-diagnosed macOS-only
bug: "sharedHTTPClient... defeats the stale-pooled-connection hang...
reproduced on BOTH chatgpt and ollama... surfaces on macOS far more than
Linux because macOS keeps dead pooled connections around longer." The
existing mitigation (ResponseHeaderTimeout=120s, IdleConnTimeout=30s)
catches a reused connection that never responds at all, or one that sat
idle too long.

Traced a live report that doesn't fit either case: a session accumulated
301 real completion tokens over ~12.5 minutes (~0.4 tok/s) on
chatgpt/gpt-5.5 before being manually cancelled - not silent, just
catastrophically slow, on a retry shortly after a prior attempt on the
same host. That's a third failure mode: a reused connection that's
alive-but-severely-degraded, still delivering real bytes (enough to keep
resetting Zero's stream idle/content-stall watchdogs, which only fire on
true silence) but never at a usable rate. Basic network diagnostics on
the affected machine (DNS, TCP connect, TLS handshake) were all healthy
and routed directly with no VPN/proxy involved, pointing at the same
connection-reuse class of bug rather than a local network misconfig.

DisableKeepAlives removes pooling from the equation entirely rather than
just tightening the timeout window, since a degraded-not-dead connection
isn't reliably distinguishable from genuine backend slowness once inside
the stream. Scoped to darwin only via runtime.GOOS: a fresh TCP+TLS
handshake per request costs low tens of milliseconds (measured ~92ms
against a real host on the affected machine) against potential
minutes-long stalls, and Linux/Windows don't exhibit this OS-level
pooled-connection behavior, so they keep full connection reuse.

New test: TestHTTPClientReturnsStallHardenedSharedClient extended to
assert DisableKeepAlives matches runtime.GOOS == "darwin".

KRATOS 33410d8730 fix(tui): make the stall watchdog visible before it fires, not just after (#357)
Zero already has a content-stall watchdog built specifically for this
exact case (providerio.ErrStreamStalled's own doc comment: "observed on
chatgpt/gpt-5.x and ollama reasoning models") - a heartbeating-but-silent
upstream is aborted after idleTimeout * StreamContentStallFactor (5min *
2 = 10min by default). It works. The gap is that until it fires, the
"still generating... Xs" cue is the ONLY signal the user has, and it
looks completely identical whether real (if slow) content is still
coming or the stream is already dead and just hasn't been caught yet -
confirmed against a live report where the token count sat frozen for
7+ minutes with no way to tell from the UI alone.

Past half the effective idle timeout, quietGenerationHint() now escalates
to name what's actually happening and when Zero will act on its own:
"still generating... Xs - unusually quiet, Zero will auto-recover by
~Ys if it doesn't resume". Exported StreamContentStallFactor from
providerio (was unexported) so the TUI can compute the same ceiling the
watchdog itself uses, instead of duplicating the constant.

New test: TestQuietGenerationHintEscalatesPastHalfIdleTimeout, using
ZERO_STREAM_IDLE_TIMEOUT to shrink the timeout so the test runs fast
while exercising the exact same math the real watchdog uses.

KRATOS 7fb0092de7 fix: agent runtime resilience — stream stalls, weak-model tool args, and sub-agent reliability (#349)
* fix(local): defeat the macOS stale-pooled-connection hang (transport + stall-retry)

Root cause (you confirmed it: both chatgpt AND ollama hung, only on macOS): providers
fell back to http.DefaultClient, whose pooled keep-alive connections get reused on a
later turn after the server/NAT silently dropped them. The model call is a POST
(non-idempotent), so Go won't auto-retry it on a fresh conn — it blocks forever.
macOS keeps dead pooled conns around longer than Linux, so it reproduced on macOS only.

1. providerio.HTTPClient now returns a shared, tuned transport (ResponseHeaderTimeout
   60s bounds a hung POST that gets no response; IdleConnTimeout 30s stops dead conns
   from lingering to be reused). Routed openai/codex through it too (anthropic/gemini
   already used HTTPClient). Slow first tokens / long reasoning are unaffected — the
   header timeout only bounds time-to-first-response-header, not the stream body.
2. Agent loop now retries a stream idle/stall timeout that produced NO output yet, on
   a fresh connection (capped + backoff). A partial-output turn is NOT retried (would
   duplicate). Recovers any stall that slips past the transport timeout.

Local only — not pushed.

* fix(local): tolerate concatenated tool-arg JSON + widen response-header timeout

1) Weak models (minimax-m3, glm) pack MULTIPLE concatenated top-level JSON objects
   into one tool-call arguments slot ({A}{B}), which json.Unmarshal rejects with
   'invalid character {' after top-level value' (~9 failed tool calls/session).
   New recoverableToolArguments returns the first JSON value ONLY when the payload is
   one value optionally followed by more WHOLE JSON values; it rejects a bad/truncated
   first value OR trailing NON-JSON garbage ({"x":1}xyz) so genuine corruption still
   errors (adversarial-review fix). decodeToolArguments uses it at the central dispatch
   (executeToolCall) so {A}{B} runs the first object; historySafeToolCalls uses the
   SAME helper so the replayed transcript records the recovered first object (not {}),
   keeping dispatch and history consistent. Truly-malformed JSON still hits the
   existing sanitize-to-{} + retry path. Trailing objects are dropped (the model
   re-issues on a later turn).

2) Raise the shared transport ResponseHeaderTimeout 60s -> 120s so a slow cloud proxy
   (ollama *:cloud) that withholds its 200 header until first token isn't wrongly
   aborted; still bounds a truly dead reused connection.

Local only — not pushed.

* feat(local): add /turns command + raise default maxTurns 30->50

Agentic multi-step runs (build + delegate + swarm + MCP + self-verify) routinely hit
the 30-turn ceiling mid-task and never reached the later steps; removing /mode earlier
also left NO interactive way to raise the budget.

- /turns [n]: per-session tool-turn budget setter (commandGroupSession), mirroring
  /selfcorrect. Empty/status shows the current budget; a positive int sets
  agentOptions.MaxTurns (read by the run at model.go); clamped to maxTurnsCeiling=500
  to guard against typos; invalid/non-positive shows usage without changing it.
- defaultMaxTurns 30 -> 50 (matches the old 'deep' preset). Raise per-run with /turns
  for long tasks (e.g. /turns 150 for a full acceptance run).

Local only — not pushed.

* fix(local): swarm reports failed members as failed + sub-agents inherit /turns budget

Issue B — a swarm member whose child exited non-zero (e.g. exit 4 / max-turns) was
recorded [done] (swarm_status '0 failed'), so the orchestrator — which can't see the
AGENTS panel — trusted incomplete work. The specialist launcher ignored
res.Result.Status; it now surfaces a StatusError result as a member FAILURE
(errors.New(report)) so the swarm marks it [failed]. Added Coordinator.FailWithSession
and switched the member watch path to it so a failed member keeps its session id
(still drillable) and its report rides along as the failure message.

Issue A — a member hit its OWN turn limit because /turns raised only the parent's
budget; children re-resolved config.json's default. New config.SetMaxTurnsEnv exports
ZERO_MAX_TURNS, read in applyEnv -> cfg.MaxTurns; /turns now exports it so spawned
sub-agents / swarm members (which inherit the env) run with the same budget. A
non-numeric/zero env value never clobbers the configured budget.

Tests: launcher non-zero-exit -> failed (+ session kept); SetMaxTurnsEnv round-trip
+ garbage-env guard; /turns exports + clamps the env. Full gate green (73 pkg).

Local only — not pushed.

* fix(local): corrective error for unknown specialist name + clamp ZERO_MAX_TURNS

1) A model that invents a specialist name (validator-runner, file-creator,
   file-writer — none registered) got an opaque 'specialist not found' and kept
   spawning doomed sub-agents. loadManifest now lists the available specialists and
   notes that 'worker' has shell/edit while explorer/code-review are read-only, so the
   model self-corrects to a capable specialist. New availableSpecialistList helper.

2) Defense-in-depth (review nit): applyEnv now clamps an inherited ZERO_MAX_TURNS to
   MaxTurnsCeiling, so a raw shell 'export ZERO_MAX_TURNS=999999' can't bypass the
   /turns ceiling. Ceiling promoted to config.MaxTurnsCeiling (single source of truth,
   referenced by the TUI /turns clamp).

Tests: unknown-name error lists worker/explorer/code-review; applyEnv clamps an
over-ceiling env value. Full gate green (73 pkg).

Local only — not pushed.

* fix(local): surface sub-agent kill signal instead of opaque exit -1

When a sub-agent child is terminated by a signal, command.Wait returns an ExitError
whose ExitCode() is -1, losing the cause. Capture ProcessState.String() (portable,
e.g. "signal: killed") into ChildRunResult.Signal and have BuildFinalResult render
it — "Subagent terminated by a signal (signal: killed) — killed before it finished.
Likely causes: the OS out-of-memory killer ... a timeout, or cancellation." — instead
of an opaque "Subagent failed (exit -1)". The message lists causes rather than
asserting OOM, since timeout/cancellation also SIGKILL the child. A captured signal
always surfaces even if a late run_end reported a clean exit. The background task
path (which can't carry the signal name) emits the same hint for a negative exit code.

* address CodeRabbit review on #349

- loop.go: gate stall-retry on a turn-level forwardedAnything flag (wrapped
  callbacks), so a retry never re-streams on top of output already forwarded earlier
  in the turn (e.g. across the reactive-compaction retry). New test covers a
  reasoning-then-stall (collected.Text empty but output forwarded).
- loop.go: route a reissued stream's non-stall error through the SAME recovery as
  the initial stream (image-rejection wrapping / context-limit compaction) via a
  shared recoverStreamError closure, instead of returning it raw.
- exec.go: drop the hardcoded worker/explorer/code-review guidance from the
  unknown-specialist error; rely on the dynamically-rendered available list (a
  custom registry may not have those names).
- streamer.go: kill-signal message lists OOM/timeout/cancellation evenhandedly
  instead of asserting OOM (the branch also covers timeouts/cancellations).
- launcher_specialist.go + exec.go: preserve the child SessionID on a post-start
  failure too, so FailWithSession keeps those failed members drillable.
- model.go: block /turns while a run is active (mid-run change would make the
  inherited ZERO_MAX_TURNS budget inconsistent for later-spawned sub-agents).

KRATOS 02a3d12f34 fix(providerio): bound heartbeat-but-no-output streams so they can't hang forever (#347)
* fix(providerio): bound heartbeat-but-no-output streams (content-stall watchdog)

A stalled-but-alive upstream hung the agent indefinitely: SSE keep-alives reset the
idle watchdog (intentionally — a heartbeating upstream isn't 'dead', and aborting it
killed healthy long requests), so a stream that heartbeats while producing nothing
never tripped the idle timeout and there was no other ceiling. Observed on both
chatgpt/gpt-5.x (Codex) and ollama minimax-m3 — different provider code, same shared
providerio SSE loop — so the fix belongs here, once, for every provider.

Add a second 'content' watchdog alongside the idle one: keep-alives still reset idle
(no regression for heartbeating connections), but only REAL data lines reset the
content watchdog. If no data arrives for streamContentStallFactor (2) × the idle
timeout, abort with ErrStreamStalled instead of hanging. A slow-but-producing stream
(data between heartbeats) keeps resetting content and is never killed.

Contained to internal/providers/providerio — no provider/caller changes.

* fix(providerio): surface ErrStreamStalled in callers + widen flaky test margins

Address review:
- All four provider stream handlers (openai, codex, anthropic, gemini) now treat
  ErrStreamStalled in the same branch as ErrStreamIdle, via a new
  providerio.StreamTimeoutMessage helper that gives the stall a distinct, accurate
  message (it reports the content window and does NOT claim the upstream stopped
  sending data — keep-alives were still arriving). Previously a stalled stream fell
  through to the generic provider-error path.
- Widen the content-watchdog test timing margins (idle 100ms, data/keepalive every
  30ms) so CI/GC jitter can't trip the idle watchdog and mask the content path.
- Add a StreamTimeoutMessage unit test.

KRATOS a0548d707b test(providers): isolate the OAuth store in the chatgpt Codex routing test (#346)
TestNewRoutesChatGPTCatalogToCodexProvider asserts the chatgpt-account-id header is
empty when no OAuth login is stored, but never redirected the token store — so on a
developer machine with a real chatgpt login it read that login and failed (it still
passed in CI, where no token exists). Point ZERO_OAUTH_TOKENS_PATH at an empty temp
path, mirroring TestNewRoutesChatGPTCatalogWithStoredAccountID, so the test is
deterministic regardless of the developer's stored credentials.

KRATOS 83a371d669 fix: stream Codex reasoning + drop swarm agents on their own completion (#345)
Two agent-visibility fixes surfaced diagnosing a 20-minute gpt-5.5 step and an
'agents never disappear' report.

A) Codex Responses path streamed no reasoning, so a long thinking phase produced
   zero visible output and read as a hang (the activity clock never advanced).
   Root cause: the request never asked for a reasoning summary and the parser had
   no case for reasoning deltas. Now request reasoning.summary="auto" and forward
   response.reasoning_summary_text.delta as StreamEventReasoning — the existing TUI
   handler renders it live and refreshes the activity clock.

B) A finished swarm member stayed in the AGENTS panel until the whole turn ended.
   Now it drops once ITS OWN task completes (fade over the linger window, then
   remove), independent of the overall run — matching how finished specialists
   already behave. Running members and mid-flight collect are unaffected.

KRATOS cfd065b565 fix(openai): always send message content so strict OpenAI-compatible servers accept it (#343)
Some OpenAI-compatible endpoints (e.g. glm-* on Ollama-cloud) reject a request whose
message 'content' is absent or null with HTTP 400 'invalid message content type:
<nil>'. The chat-completions mapper relied on 'content,omitempty', so a message with
empty text (a tool result, an assistant turn that only makes tool calls, or a
sub-agent that failed with no output) serialized with no content field at all.

- Drop omitempty on chatMessage.Content and always set it (to "" when there is no
  text), so contentless messages serialize as "content":"" instead of being
  dropped. Standard OpenAI/xAI/groq already tolerated the omission; this makes the
  strict servers work too.
- Skip a degenerate assistant turn that has neither text nor tool calls, mirroring
  the Anthropic/Gemini mappers (which already drop empty turns).

Fixes the failure seen on glm-5.2:cloud after a sub-agent failed with empty output.

Vasanth T d99ac4d1e3 fix(openai): forward reasoning effort to the Codex Responses API (#336)
The Codex provider speaks the Responses API, where reasoning_effort is nested
under `reasoning.effort` rather than sent as a top-level field. buildResponsesRequest
never set it, so a user's chosen effort was silently dropped for every Codex
model — the request always ran at the model default.

Add a `reasoning` object to the Responses request and populate it from the
request's effort, reusing the chat path's openAIReasoningEffort normalizer so
only API-accepted values (minimal/low/medium/high) are sent and an empty or
unsupported effort omits the field (no empty object, no 400).

Vasanth T 29246e5659 fix(providers): make the stream idle timeout global, configurable, and less aggressive (#285)
A long generation could die with "provider stream error: idle timeout after
1m30s (upstream stopped sending data)". The 90s idle watchdog was duplicated as
defaultStreamIdleTimeout in three providers (anthropic, gemini, openai; codex
inherits openai) and wired to no config, so a slow cloud/reasoning backend that
goes silent without SSE keep-alives for >90s was killed mid-stream.

Centralize it in providerio:
- providerio.DefaultStreamIdleTimeout — single source of truth, raised 90s -> 5m
  so a genuine silent pause has real headroom. The watchdog still resets on SSE
  keep-alive comments, so a heartbeating-but-slow upstream is never aborted; this
  only changes how long true silence is tolerated before aborting a hung stream.
- providerio.ResolveStreamIdleTimeout(option): precedence is explicit option >
  ZERO_STREAM_IDLE_TIMEOUT env (a Go duration or bare seconds; 0/off/none
  disables the watchdog) > default. All providers resolve through it, so one env
  var tunes every provider at once.

Removes the three duplicated consts. Existing idle tests (which set an explicit
short StreamIdleTimeout) keep passing because an explicit option still wins. Adds
resolver tests (precedence, env parsing, disable, typo-falls-back-to-default) and
documents ZERO_STREAM_IDLE_TIMEOUT in the README.

KRATOS 09888e64e8 providers: surface non-normal terminal turns instead of silent empty completions (#263)
* providers: surface non-normal terminal turns instead of silent empty completions

Four stream-adapter cases where a non-normal turn was treated as a clean
empty completion, hiding the real outcome. Each ships a regression test.

- openai/codex: a tool call arriving with output_index 0 and no item_id
  had its argument deltas dropped (the call dispatched with empty JSON).
  output_index is now a *int so a real 0 is distinguishable from absent.
- openai/codex: response.failed / response.completed with a nil payload
  returned silently with no terminal event; now failed emits an error and
  completed emits done, so a failure is never masked as an empty success.
- gemini: terminal finishReasons (RECITATION, MALFORMED_FUNCTION_CALL,
  IMAGE_SAFETY, OTHER, LANGUAGE, UNEXPECTED_TOOL_CALL) were treated as a
  normal stop; safety reasons now map to content_filter and the rest
  surface the raw reason so the truncation notice fires.
- anthropic: stop_reason "refusal" was treated as a normal completion;
  it now maps to content_filter.

* address review: restore Gemini integration/tool-call tests; justify pause_turn

Review follow-ups on the provider silent-failure fixes:

- Gemini: restore the end-to-end finish-reason and dropped-tool-call tests that
  the earlier refactor removed, alongside the mapFinishReason unit test. This
  re-covers the full SSE -> done-event wiring (MAX_TOKENS -> length, SAFETY ->
  content_filter, normal STOP -> "") and the nameless-functionCall drop signal,
  and adds a RECITATION integration test that exercises the M3 widening through
  the streaming path (not just mapFinishReason in isolation).

- Anthropic: document why pause_turn is classified as a normal stop — it is the
  long-running-turn pause (server-side tools) the client resumes by sending the
  response back, not a truncation/refusal, so it correctly maps to "" rather than
  firing a spurious truncation notice.

gofmt/vet/build clean; gemini/anthropic/openai suites pass.

* codex: surface response.failed even when the payload omits the error object

A response.failed terminal event carrying a non-nil Response whose `error`
object is null/omitted (the backend can report the failure only via `status`)
fell through to a clean StreamEventDone — reporting a real failure as a normal
successful turn. Only the nil-payload path was guarded. Branch on the failed
terminal (event type / Response.Status) before the clean-done fallthrough and
emit StreamEventError. Adds a regression test for the non-nil-payload-without-
error case (verified to fail without the fix).

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
read_file in all of them; updated the default-allowlist test accordingly.

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/...

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.

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.

* 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.

* 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).
