Vasanth T 021281ebba fix(cli): report MCP servers that failed to start (#822) (#827)
* fix(cli): report MCP servers that failed to start (#822)

`zero mcp check` inspected only the error returned by registration and then
printed "is reachable". RegisterTools is best-effort by design, so a server
that fails to connect is recorded on the runtime and registration returns
nil. That is right for startup, where one bad server must not stop Zero
launching, and wrong here: this is the command a user runs when a server is
misbehaving, and it told them the broken server was fine.

The failure data already existed as SkippedServer{Name, Err}; nothing
consumed it in this path. The check now fails with the recorded error, in
both text and JSON output.

Covered by a test that spawns a genuinely missing command rather than
stubbing the runtime, because the defect was precisely a mismatch between
what registration returns and what it records. Reverting the fix makes it
print "MCP server broken is reachable. 0 tool(s) available."

* test(cli): cover the unreachable --json contract

The text path was covered and the JSON path was not, though the change
adds its own return with a different payload: status "unreachable" plus a
redacted error, rather than status "ok" with a tool count. A caller
parsing that shape was relying on something nothing pinned.

Reverting the fix now fails both cases. The JSON one is the more useful
of the two, because the wrong output is still valid JSON and would decode
cleanly into a caller expecting success.

8e266797a8 perf: improve harness context efficiency (#838)
* Improve harness context efficiency

* Address harness efficiency review findings

* Make recaps idle and cancellable

Delay recap generation until the session has been inactive, orient it around the active goal and next task, cancel stale work on activity, and render the result ephemerally above the composer.

Also strengthen the formatter safety regression to exercise formatter-modified edit output.

* Track every replace-all edit span

Translate each replacement into its post-edit line range, including cumulative shifts from earlier replacements, so follow-up edits remain authorized for every model-supplied change.

* Make review regressions cross-platform

Verify replace-all tracking through the canonical edit tool path instead of a platform-sensitive temp path, and cover cancellation when recaps are disabled during generation.

* fix(tools): derive SeenWhole from the recorded ranges

SeenWhole was a flag set only by a SINGLE read covering the file, while
SeenRange judged coverage from the accumulated ranges. The two then
disagreed about identical reads: after reading lines 1-50 and 51-100 of a
100-line file, SeenRange(1,100) was true and SeenWhole was false.

That matters because write_file gates overwrites on SeenWhole. A file past
the read byte budget cannot be read whole in one call — the read is
truncated and RecordSeenRange is correctly skipped, since the model did not
see those lines — so no sequence of reads could ever set the flag, and the
overwrite was refused permanently with:

    the intended change depends on content that has not been read exactly
    in this session. Read the affected lines with read_file, then retry.

Advice that could not change the answer. edit_file was unaffected because it
gates on SeenRange, so the escape was to edit rather than rewrite, but a
model following the error text would loop.

SeenWhole is now computed from the ranges against the file's recorded line
count, so scoped reads that together cover a file make it writable and the
error text becomes actionable. The observation carries that line count, and
a read reporting a different one clears the accumulated ranges: they
describe a shape the file no longer has.

Coverage is judged by merging sorted ranges rather than walking every line
against every range, which the previous SeenRange did — same answer, and it
no longer scans line-by-line over a large file.

* test(tools): key the large-file test on the resolved path

read_file resolves the workspace root through EvalSymlinks before recording
anything, so the tracker is keyed on the resolved path. The test asserted
against the raw t.TempDir() path, which is the same string on Windows and a
different one on macOS, where the temp dir sits under /var — a symlink to
/private/var. The SeenWhole assertions would have looked up a key that never
existed: passing here, failing on macOS CI.

Also switches the line generator to fmt.Fprintf (staticcheck QF1012).

Both from CodeRabbit on #842.

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

* test(tools): actually switch the line generator to fmt.Fprintf

The previous commit's message claimed this was done. It was not: the edit
silently did not apply and I reported it fixed without re-reading the file,
so builder.WriteString(fmt.Sprintf(...)) survived at the head — caught by
@anandh8x, not by me.

Verified this time by running the linter rather than by reading the diff:
golangci-lint --enable-only unused,ineffassign,staticcheck ./internal/tools/
reports 0 issues.

* fix: keep exact-read workflows recoverable

* test: cover permission normalization wiring

* fix: commit file observations after output budgeting

* fix: defer file observations across retries

* test: normalize patch line endings

15b7a5475c fix(acp): interrupt idle reads on cancellation (#782)
* fix(acp): interrupt idle reads on cancellation

* fix(acp): make idle-read interruption per-Read, not per-Serve-call

Addresses the P2 on #782.

The previous design raced a single, whole-connection Once (endRead) between the
read loop's own "I have a terminal result" claim and a watcher goroutine's
"ctx is done, treat this as interrupted" claim. This has a real, deterministic
failure mode that has nothing to do with goroutine-scheduling luck: bufio.Reader
can obtain data AND a terminal error from ONE underlying Read call (io.Reader
explicitly permits returning (n>0, err) together). If a line delimiter is found
within that data, ReadBytes returns the line with a nil error for that call, but
bufio caches the error internally and returns it — without ever touching the
underlying reader again — on the very next ReadBytes call. If cancellation
happens in the gap between that first, successful read and the next one (e.g.
while a synchronously-dispatched handler is still writing its response), the
watcher's ctx.Done() case fires and claims the Once BEFORE the read loop ever
gets back to a ReadBytes call — so when the cached error then surfaces (with
zero contact with the underlying reader, let alone anything closing it), it is
misattributed as a cancellation-driven interruption and silently swallowed as a
clean shutdown, hiding a genuine broken transport.

The fix moves interruption-detection down to the Read call itself instead of
bracketing the whole Serve loop. interruptibleReader wraps the connection's
reader: each Read runs the underlying call on its own goroutine and races it
against ctx.Done(). If the underlying call finishes first, its result is
returned untouched — cancellation a moment later has no bearing on a call that
already had its answer. If ctx.Done() fires first, the reader is closed (when
closable) to nudge a genuinely blocked read, a generation counter is bumped, and
the call still waits for and returns the underlying call's own result rather
than a synthesized one.

Serve then brackets each ReadBytes call (which may invoke the wrapped Read zero
or more times — zero when bufio answers from its own buffer, including a
previously-cached error) with a snapshot of that counter before and after. A
read whose bracket shows no change was never raced against cancellation — either
answered from the buffer or genuinely completed before ctx.Done() could matter —
so its outcome is reported truthfully regardless of the ctx state by the time it
surfaces. Only a bracket that changed proves this specific call actually took
the cancellation branch.

Verified the fix has teeth: reverted to the original implementation and
confirmed the new regression test (which forces the exact bufio-caching
sequence deterministically, with a panic guard proving the underlying reader is
never called a second time) fails 100% of the time against it, then restored
the fix and confirmed it passes.

Also applied the two open review threads on the existing tests: readStarted and
writeStarted are now buffered channels with non-blocking sends rather than
close(), so a future change causing an extra read or write can't panic on a
double-close.

Validated with go build/vet/test on Windows, plus go vet/build and
`go test -race ./internal/acp/... -count=50` (and count=100 focused on the
cancellation/error tests) under WSL/Linux — this session's Windows host has no
C toolchain for -race directly.

* fix(acp): preserve decided read results and require explicit reader ownership

Addresses jatmn's two #782 review findings:

- interruptibleReader.Read's select between resultCh and ctx.Done()
  chooses pseudo-randomly when both are ready, so a real terminal read
  error decided just before cancellation could be misattributed to
  shutdown and silently swallowed. Re-check resultCh non-blockingly
  before claiming a call for cancellation.

- NewConn inferred reader ownership from an io.Closer assertion and
  closed any reader that happened to implement it, including one a
  caller merely borrowed. Split into NewConn (never closes r) and
  NewOwnedConn (explicit ownership, closes r on cancellation), and
  switch the sole production call site (process stdin) to the latter.

Also applies CodeRabbit's atomic.Int64 and leading-ctx-parameter nits.

Vasanth T d82b94defe test(cli): order the prewarm probe against the turn (#809)
* test(cli): order the prewarm probe against the turn

TestRunExecOptimizedSessionUnderGate intermittently sees zero prewarm HEAD
probes on the Windows runner. It polled for up to 5s after the run returned,
reasoning that the deadline exceeded the 3s prewarm timeout so a slow probe
could not flake it. That reasoning does not hold. The probe is issued on the
run's context and runExec cancels that context as it returns, because the stop
function signalContext hands back is a CancelFunc. Once the run is over the
probe is cancelled rather than slow, so polling cannot observe one that has not
already landed, at any deadline.

Against a mock server the turn finishes in microseconds, which leaves the probe
racing teardown. The turn now blocks until the probe arrives, giving it a
window while the run is still alive. The wait is bounded, so a probe that never
fires still fails the assertion with a useful message.

This widens the window rather than closing it: prewarmTimeout is armed inside
the probe goroutine, so holding the turn cannot extend it. The comment says so,
and names prewarmTimeout as the thing to look at if this ever recurs.

* test(cli): fail when the prewarm hold gives up

The bounded wait let the turn proceed after its guard expired, so a probe that
arrived late still left the count at 1 and the test passed. That proves the
probe was eventually received, not that it preceded the turn, which is the only
thing this test claims. Raised by CodeRabbit.

The expiry is now recorded and checked before the count, since the count cannot
tell the two apart.

Verified by suppressing the probe, which makes the guard expire: the assertion
fires with its own message rather than the count assertion, and the run takes
the full guard duration.

Vasanth T 3524f795e5 fix(cli): warn when ZERO_PROVIDER overrides a providers-use selection (#767)
Closes #721.

`zero providers use <name>` wrote activeProvider to config.json and reported
"Active provider set to <name>" even when ZERO_PROVIDER was set, which applyEnv
makes win over config.json unconditionally. So the switch was reported as a
success while `providers current` still showed the env-pinned provider, a silent
no-op.

Detect the override and say so: the text path prints a note to stderr naming the
env var and the provider that stays active, and the --json path adds
effectiveProvider / overriddenByEnv fields so a machine consumer is not misled
either. The config write still lands unchanged; only the reporting is honest.

The env read is injected via a new appDeps.getenv (os.Getenv in production, left
nil by fillAppDeps like exportActiveProvider) so tests stay hermetic against an
ambient ZERO_PROVIDER. The related env-derived-profile "not found" case the issue
also mentions is already handled by the unpersisted-provider path (#707) and #716.

KRATOSandKRATOS a21a052a4a feat(sandbox): disable the sandbox via config (#687) (#746)
* feat(sandbox): disable the sandbox via config (#687)

Add a sandbox.enabled field (`"sandbox": {"enabled": false}`). ModeDisabled
already short-circuits the engine but had no config surface.

- SandboxConfig.Enabled *bool (pointer distinguishes an explicit false from an
  omitted key).
- mergeConfig honors it (global config / CLI); applyConfiguredSandboxPolicy maps
  enabled:false to ModeDisabled.
- mergeProjectConfig intentionally does NOT merge it: a cloned repo must not be
  able to disable the sandbox that constrains it — same posture as
  AdditionalWriteRoots and the Network tighten-only rule.

* fix(config): honor sandbox.enabled from the CLI override path (#687 review)

applyOverrides copied BlockUnixSockets/MonitorDenials but not the new Enabled
tri-state pointer, so a CLI/programmatic Overrides{Sandbox:{Enabled:&false}} was
dropped — contradicting the 'global config / CLI can disable' contract. Preserve
the pointer in applyOverrides (runs after all config sources, so an explicit
override wins) and add a resolver regression test: an explicit false override
disables, and an explicit true override wins over a lower-precedence config false.

* fix(config): keep sandbox.enabled out of the provider-command path (#687 review)

mergeConfig now copies Sandbox.Enabled, and it is shared by two callers: the
global-config merge (trusted) and the provider-command merge (not). A provider
command is an arbitrary executable named in config, and LoadProviderCommand
parses its stdout into a full FileConfig -- so one returning a valid provider
plus {"sandbox":{"enabled":false}} could disable the sandbox meant to constrain
it, despite the setting being documented as global-config/CLI only. Confirmed
reproducible in both directions before the fix.

Clear Sandbox.Enabled from the provider-command config before merging, mirroring
the carve-out mergeProjectConfig already applies for the same reason. Done at the
call site rather than inside mergeConfig because that helper must keep honouring
the setting for the trusted global-config merge.

Adds TestResolveSandboxEnabledIgnoredFromProviderCommand covering both
directions (cannot disable, cannot enable) and asserting the provider itself is
still applied, so the guard cannot be satisfied by dropping the command wholesale.

Vasanth T 378d538e24 perf(agent): execution profiles with one-shot posture escalation (PR10b+PR10c) (#740)
* perf(agent): execution profiles, --exec-profile, bench passthrough, TUI /profile (PR10b+10c)

* fix(execprofile): harden profiles against review findings

- fast escalates on critical-risk mutations, not high: the sandbox marks
  every shell command high before command analysis, so a high trigger
  spent the one-shot on the first go test of any task
- escalation can now restore the provider-default effort a profile
  displaced (PostureEscalation.RestoreDefaultEffort; a plain empty
  target means leave untouched)
- TUI /turns while a profile is active pins the budget: disarms the
  escalation turn target (mirroring exec's explicit --max-turns rule)
  and profile reverts use touched bits instead of value equality, so
  explicit choices survive even when they coincide with profile values
- spec-draft runs get the same escalation policy as the main run
  instead of the displaced budget with no safety net
- bench validates and canonicalizes --exec-profile before spawning:
  an unknown name previously produced an exit-0 report full of
  millisecond usage-error walls
- turn summary prints exec-profile alongside mode; zero exec rejects
  an inline-empty --exec-profile=; balanced trace label documented and
  pinned as deliberate attribution

* fix(execprofile): explicit effort choices disarm the escalation effort restore

An explicit effort set AFTER profile selection could be cleared by a
mid-run escalation (the effort analog of the /turns pin, introduced by
RestoreDefaultEffort): TUI /effort and Ctrl+T now disarm the restore on
a policy clone, and the spec-draft path only arms it when no explicit
--spec-reasoning-effort governs the draft.

* fix(execprofile): address review findings on the profile surfaces

- --use-spec projects away a profile's self-correct knob instead of
  silently arming an option the draft runner ignores (the explicit
  --self-correct --use-spec combination is already a parse-time error)
- RunTurnBench canonicalizes and validates ExecProfile at the library
  boundary, so a direct caller's casing/whitespace cannot fork report
  labels and an unknown name fails before anything runs
- reverting a profile whose displaced budget was zero clears
  ZERO_MAX_TURNS (SetMaxTurnsEnv ignores zero, so sub-agents would have
  kept the removed profile's budget)
- the TUI effort-disarm test fails instead of skipping when the catalog
  stops filling low effort

* fix(tui): reconcile an active profile's effort fill on model switch

The fill is per-model, not a session preference: fast selected on a
model without low fills nothing, and switching to a model that supports
it should behave like selecting the profile there; the reverse switch
must not keep sending a level the destination does not support. Both
switch paths (the /model command and the cross-provider picker) now
re-derive the fill, leaving explicitly touched efforts alone and
keeping the escalation's effort restore in step. Also: the revert-env
test asserts key removal via LookupEnv, and applyProfileTurnBudget's
pinned-budget parameter is named and documented as covering mode
presets, not just the flag.

* fix(tui): void profile effort bookkeeping when the model-switch drop erases it

The /model path's pre-existing unsupported-effort drop ran before the
profile reconciliation and left contradictory state behind: a dropped
touched override kept blocking the profile from governing, and a
dropped profile fill left a stale applied value with the effort restore
still armed. The drop itself is load-bearing (the TUI run path forwards
the effort to the provider unfiltered), so instead of preserving a
known-unsupported level, the voided choice now resets the profile's
effort bookkeeping and the reconcile re-derives from scratch. The whole
sequence lives in one ring-parameterized helper driven by the switch
target's authoritative ring, unit-tested against synthetic rings for
both the void-then-refill arc and the supported-override survival.

* fix(tui): only drop an explicit effort when the target ring is authoritative

A nil ring meant both a catalog model with no effort controls and a
live-discovered custom model the catalog cannot vouch for. The drop now
requires an authoritative ring (a resolved catalog entry, whose ring may
legitimately be empty); an unknown ring preserves an explicit preference,
matching the cross-provider picker's behavior, while the profile's own
fill still applies only where support is known.

directCommandPlan (used when the native sandbox backend is unavailable,

left Env nil whenever spec.Env was nil, so exec.Cmd inherited the full

dynamically named ZERO_OAUTH_<NAME>_CLIENT_SECRET variables leaked
through that path even though the wrapped sandbox plans already
scrubbed them.

Route direct plans through scrubSensitiveEnv the same way wrapped

still applies. Adds a regression test covering the degraded-fallback
path with both a configured and a dynamically named secret.

* fix(aimlapi): address review findings in onboarding flow

- topup: use errors.As for the 5xx retry check so a wrapped APIError
  still retries instead of aborting a paid checkout.
- onboarding: a Path-A top-up on an email with no account now lands on a
  single coherent "key saved, balance not topped up" screen instead of a
  green "ready" plus a red error.
- onboarding: an empty amount field is rejected instead of silently
  falling through to the $25 default.
- collapse the two identical top-up prompt constants into MsgTopUpPrompt
  and drop the dead amountPrompt() branch.
- reuse stdlib maps.Clone instead of a third bespoke header-copy helper.

euxaristia 9acb4113cc feat(cli): show ZERO wordmark on --version (#673)
* feat(cli): show ZERO wordmark on --version

The TUI's empty-state ZERO ascii art gets exposed via a new tui.Wordmark
helper and printed above the version line for `zero -v`/`--version`.
Coloring only applies when stdout is a real TTY and NO_COLOR isn't set,
so redirected or piped output (scripts parsing the version) stays plain.

* fix(release): match --version output by suffix, not exact string

The release smoke check compared zero --version output to an exact
"zero <version>" string, which broke once --version started printing
the wordmark above the version line. Check for a "version: <version>"
suffix instead so the smoke check doesn't couple to the wordmark art.

* fix(cli,tui): keep --version machine-readable off-TTY, drop wordmark color

- When stdout is not a terminal, --version prints exactly "zero <version>"
  again: pipes, redirects, command substitutions, and the release smoke
  contract all parse that single record, so the banner is a TTY-only
  affordance now.
- The TTY path keeps the banner but restores "zero <version>" as the
  version record instead of "version: <version>".
- Wordmark renders uncolored: only newModel resolves --theme/ZERO_THEME,
  so painting the global dark palette here was unreadable on light
  terminals. The terminal's default foreground works on any background.
- smokeVersion goes back to requiring the exact "zero <version>" output
  instead of the suffix match that papered over the banner.

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.

Leonardo Faoro 7d579996b4 feat(skills): discover shared ~/.agents/skills with multi-root skill loading (#696)
* feat(skills): discover shared ~/.agents/skills with multi-root skill loading

Add ~/.agents/skills as a read-only global discovery root after the
primary
Zero skills dir and before plugin roots. Unify runtime and CLI discovery
on
one multi-root path (DiscoveryRoots / LoadFromRoots / GlobalRoots) and
always
register the multi-root skill tool so bare runs and plugin runs share
the
same load surface.
Install/remove/lock still target only the primary Zero skills directory.
Fixes #610

* docs(skills): note lock stays on the primary write root

Document that install/remove/lock target only the primary Zero skills
directory, matching multi-root discovery write-root isolation.

* fix(skills): bubble primary root load errors from LoadFromRoots

Return non-missing failures from the first non-empty skills root so a
broken primary dir is not reported as an empty skill list. Keep fail-open
behavior for optional roots (~/.agents/skills, plugins).

* fix(skills): treat non-directory skills root as error on Windows

Windows maps ENOTDIR to ErrNotExist, so ReadDir on a regular file looked
like a missing skills dir. Reclassify existing non-directories and assert
the portable load behavior in tests.

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.

euxaristia 6fc1220f6a fix(sandbox): scrub sensitive credentials from sandbox environment (#660)
* fix(windows): retry atomic file renames on Access is denied / Sharing violation

* test(swarm): add unit tests for rename retry and non-retryable errors

* test(swarm): skip TestMailboxRenameRetry on non-Windows platforms

* fix(sandbox): scrub sensitive provider credentials from sandbox env

* refactor(sandbox): unify environment creation and reduce lines of code

* fix(sandbox): forward workspaceRoot through sandboxEnvironment, gate Windows env on backend

* style(sandbox,swarm): remove stray blank lines flagged by gofmt

* refactor(fsutil): extract shared rename retry helper, derive scrub list from provider catalog

Address CodeRabbit review feedback:

- Add internal/fsutil.RenameWithRetry with an injectable rename override and
  move the four duplicated renameWithRetry/isWindowsSharingViolation copies
  (cron, sessions, sandbox, swarm) onto it. Mailbox keeps its rename test
  seam by passing its field through. Add fsutil tests for the Windows retry
  and non-retryable paths.
- Remove the orphaned metadata.json.tmp in cron writeJob when the rename
  permanently fails, matching the sibling writers.
- Derive scrubSensitiveEnv keys from providercatalog AuthEnvVars plus a
  static list of non-catalog secrets, so new providers are scrubbed
  automatically. AWS_PROFILE and GOOGLE_APPLICATION_CREDENTIALS stay
  because they are pointers, not secrets.

* fix(sandbox): deny sandboxed reads of cloud credential stores by default

Address CodeRabbit finding that scrubbed env pointers still left the
underlying credential files readable under the read-all workspace posture:

- Add credentialDenyReadPaths: default profile-level deny-read entries for
  ~/.aws, ~/.config/gcloud, ~/.azure, and the GOOGLE_APPLICATION_CREDENTIALS
  target file, wired into both permission profile builders so the seatbelt
  and Linux helper backends enforce them. Entries are stat-filtered and a
  store nested under a user AllowRead entry is dropped, keeping an explicit
  opt-out.
- Keep the defaults out of Policy.DenyRead, whose emptiness gates escalated
  execution, and skip Windows so the profile deny list does not flip the
  runner off the WRITE_RESTRICTED token path.
- Scrub GOOGLE_APPLICATION_CREDENTIALS from the sandbox env; keep AWS_PROFILE
  since the deny-read rule on ~/.aws is the real protection and the SDKs
  fall back to the default profile regardless.
- Add credential deny path tests, extend the scrub test, relax the profile
  test's exact deny count to containment.

* test(cli): pin HOME in sandbox policy golden test

The default credential-store deny-read entries depend on what exists in the
real home directory (the macOS CI image ships ~/.aws), which leaked host
paths into the policy JSON golden comparison. Point HOME at an empty temp
directory so the golden stays hermetic.

* fix(sandbox): protect GOOGLE_APPLICATION_CREDENTIALS without a home, retry lock violations

Address CodeRabbit review feedback:

- credentialDenyReadPaths no longer returns early when the home lookup
  fails; home-based candidates become conditional and the
  GOOGLE_APPLICATION_CREDENTIALS target is always considered.
- fsutil.RenameWithRetry also retries ERROR_LOCK_VIOLATION (errno 33),
  matching the mcp lock handling; helper renamed to
  isWindowsSharingOrLockViolation.
- Extend tests: homeless GOOGLE_APPLICATION_CREDENTIALS case and a lock
  violation step in the retry sequence.

* fix(sandbox): tighten env-scrub test assertion and add missing secret keys

TestScrubSensitiveEnv only checked an allowlist plus a length count, so a
duplicate allowed key silently replacing a required one would still pass.
Compare the exact expected key/value map instead.

Also add ZERO_WEBSEARCH_API_KEY and ZERO_DAEMON_REMOTE_TOKEN to
scrubSensitiveEnv's sensitiveKeys list: both are real bearer secrets read
from the environment but were missing from the scrub list, leaving them
readable by sandboxed commands when set in the parent shell.

euxaristia 5c4815a66e fix(sandbox): unblock git fetch/commit/add under the write-restricted sandbox (#654)
* fix(sandbox): stop blocking git fetch/commit/add by unblocking .git writes

The sandbox denied every write under .git for shell-executed commands,
so any git operation that touches its own metadata (fetch, commit, add,
pull, merge, stash) failed under the default sandbox. Narrow the block
to .git/hooks (auto-executing scripts) and .git/config (remote URLs,
credential.helper, core.hooksPath), the two subpaths that are actually
dangerous to write; the rest of .git stays writable to git subprocesses
since those writes go through git's own invariants.

The app-level auto-allow gate for direct file-tool writes (write_file,
edit_file, apply_patch) is unaffected and still treats all of .git as
protected, since hand-editing git's internals bypasses those invariants.

* test(cli): normalize Windows path separators in sandbox policy golden

The sandbox policy golden is shared across platforms, but readOnlySubpaths
carve-outs are built with filepath.Join and render as backslash paths on
Windows. normalizePortableJSONRootString only converted a bare backslash, so
the Windows smoke run diverged from the forward-slash golden. Replace all
backslashes with slashes during normalization so the shared golden passes on
every runner.

euxaristia 635c93af51 fix(agent): raise default and deep-mode turn budgets (#650)
* fix(agent): raise default and deep-mode turn budgets

The default per-run tool-turn budget of 50 was still too low for larger
multi-step tasks that span several files: agents hit the ceiling and
stopped with a "remaining work" summary instead of finishing. Raise the
default from 50 to 80.

The "deep" preset also carried MaxTurns: 50, identical to the default, so
its "larger turn budget" promise no longer held on the turn-budget axis.
Raise it to 160 so deep runs get a genuinely larger budget again.

Users can still override per-session with /turns or --max-turns (bounded
by MaxTurnsCeiling).

euxaristia b6117af86d fix(exec): stop false INCOMPLETE downgrades on conversational final messages (#608)
* fix(agent): scope self-reported incompletion to sentences about the current objective

The detector matched inability stems anywhere in the final message, so a
conversational recap of a past exchange ("You asked if I could work
autonomously ... so I couldn't actually do it at the time") downgraded a
completed run to INCOMPLETE. Match per sentence instead, drop quoted spans,
and skip sentences that retell a past exchange. The real transcript is now a
regression test, and genuine admissions still fire, both present tense and
past tense about the current task.

* feat(exec): add --no-completion-gate for conversational callers

A chat frontend driving zero exec has an operator present, so a final
message that hands the turn back ("the sandbox blocks network egress,
approve it and I'll continue") is a complete conversational answer, not an
unfinished task. The headless completion gate still stamped such runs
INCOMPLETE (exit 4) on the honest inability phrasing, and no phrase
heuristic can fix that case because the admission is true. The new flag
maps to RequireCompletionSignal=false so conversational callers can opt
out. Default behavior is unchanged.

* fix(exec): address review findings on quote stripping and --use-spec combination

stripQuoted now removes only balanced quoted spans: an opening delimiter
that never closes is restored verbatim, so a stray quote cannot swallow
the rest of the message and hide a genuine admission from the detector.
Regression tests cover dangling straight, curly, and backtick delimiters.

--no-completion-gate combined with --use-spec is now rejected at parse
time, mirroring the --self-correct check: the spec-draft path never
consults the completion gate, so the flag would be silently ignored.

beardthelionandKevin Codex a880ce80a6 feat: gate project-scoped hooks, plugins, and MCP servers behind workspace trust (#529)
* feat(workspacetrust): add exact-match trust store for project config gating

* feat(hooks): add ExcludeProject option to LoadConfig

* feat(plugins): add ExcludeProject option to Load

* feat(cli): gate project hooks and plugins behind workspace trust

Trust check lives inside newHookDispatcherWithExtra and activatePlugins
(fail-closed by construction); trustRoot is the original launch dir so a
--worktree run inherits the source repo's trust. Callers OR the skip
reports and emit one combined stderr notice.

* feat(cli): add zero trust command (trust/list/remove)

* fix(review): key spec-draft trust on the original launch dir; cover trust CLI edge branches

Spec-draft runs (zero exec --use-spec --worktree) passed the reassigned
worktree path as trustRoot, dropping a trusted repo's project hooks
(fail-closed, but breaks worktree-inheritance). Thread the captured
pre-worktree trustRoot into execSpecDraftRun. Add tests for the trust
'remove' too-many-args and --help branches, and a resolveTrust comment
noting the per-chokepoint check must not be hoisted to callers.

* test(cli): end-to-end trust-gate coverage through agent.Run and exec --worktree

Drives the real agent loop with a fake tool-calling provider so a project
beforeTool hook actually fires (or is gated away) through production code:
gate blocks a tool call via agent.Run, and --worktree / --use-spec --worktree
key trust on the original launch dir. All three are load-bearing (RED when the
gate or the trustRoot threading regresses).

* style(cli): gofmt struct alignment in exec_spec.go

* fix(workspacetrust): compare stored trust entries literally, no symlink re-resolution

External adversarial review (codex) found a false positive: IsTrusted
re-normalized stored entries on every check (Abs+EvalSymlinks), so a trusted
path later replaced by a symlink to attacker content re-resolved to the new
target and matched. Stored entries are already canonical (normalized once at
Trust time); compare them as literals and only normalize the incoming query.
Add a regression test for the symlink-retarget case.

* feat(mcp): gate project-scoped MCP servers behind workspace trust

Closes the P0 an external adversarial review (codex) found: project
./.zero/config.json stdio MCP servers spawned before the hook/plugin gate,
an ungated arbitrary-execution path that could also self-trust the workspace.
Add ExcludeProject to config.ResolveMCP (skips the project layer) and thread a
fail-closed trust check into every MCP spawn site (exec, TUI setup+refresh,
mcp tools list, mcp check); reporting sites stay ungated. Verified the sole
server-command exec (mcp/client.go) is reachable only through the now-gated
RegisterTools paths.

* test(cli): cover default-mode beforeTool firing through the trust gate

Assert a project beforeTool hook fires in the default auto and ask permission
modes (not only under unsafe), and is blocked when the workspace is untrusted,
so the gate is verified in the mode a normal run actually uses.

* docs(cli): note MCP servers in zero trust help text and doc comment

The gate covers project hooks, plugins, and MCP servers, but the help string and
runTrust doc comment listed only hooks and plugins.

* test(cli): make workspace-trust tests portable on macOS and Windows

setTrustConfigRoot set HOME on darwin, but config.UserConfigDir is XDG-first
there (=$HOME/.config), so tests wrote trust.json and user hooks.json where the
code never read them; set XDG_CONFIG_HOME on every non-Windows platform instead.

writeMarkerHook shells out to /bin/sh, absent on Windows, so its trusted-case
marker never appeared; skip it there like writeMarkerHookScript already does.

TestRunTrustAddThenList compared `trust list` output (canonicalized via
EvalSymlinks) against the raw cwd, which diverges on the Windows runner's 8.3
short names (RUNNER~1 -> runneradmin); compare the resolved path, and add
TestRunTrustListShowsCanonicalPath to exercise that via a symlink on any platform.

* feat(cli): surface the project MCP skip in the workspace-trust notice

Project MCP servers were dropped silently in an untrusted workspace: the trust
notice covered hooks and plugins but not MCP, and app.go discarded the
resolveTrust error. registerMCPToolsForWorkspace now returns a trustSkip, gated
on a new projectMCPConfigExists check plus the previously-dropped store-read
error, and emitTrustNotice is variadic so the exec, spec-draft, interactive, and
`mcp tools list` paths all fold in the MCP skip.

The skip drives the notice only; the gate stays on resolveTrust/excludeProject,
so a trusted workspace is unaffected and an untrusted one still fails closed.

* fix(cli): print zero trust --help to stdout with a success exit

zero trust -h/--help/help routed usage to stderr with the usage exit code, unlike
every other subcommand (mcp, sandbox, skills, cron, ...) which prints help to
stdout and returns success. Align it; the unknown-subcommand path still writes to
stderr with the usage exit code.

* fix(cli): gate oauth MCP login and surface mcp-check trust notice

Two project-scoped MCP activation sites were left outside the workspace
trust gate.

zero mcp oauth login loaded a project-defined OAuth server from an
untrusted workspace and ran the full discovery/registration/token-exchange
flow against its configured URL. Gate resolveOAuthServer with resolveTrust
so an untrusted clone's ./.zero/config.json OAuth server is dropped before
login, and emit the same one-line trust notice the other spawn sites use.

zero mcp check already gated the project layer but discarded the trust-check
result and never emitted the notice, so a gated project server read as a
bare "not configured". Emit the notice on the not-found branch.

The three remaining ungated resolveMCPConfig(cwd, false) sites (backends
doctor/snapshot and the extensions listing) are enumeration-only and stay
ungated.

* test(cli): adapt MCP startup-skip tests to two-arg resolveMCPConfig

PierrunoYTandCopilot App 062328b632 fix: warn about untracked scratch files left behind after a run (#571)
* fix: warn about untracked scratch files left behind after a run

Fixes #551. Headless exec runs could leave behind debug/scratch files
(e.g. _fix_test.py, _debug.py) created by write_file during iteration,
which would then be silently swept up by a later git add -A.

- FileTracker now records brand-new files (RecordCreated/CreatedFiles),
  distinct from the existing version-baseline tracking used for
  conflict detection.
- write_file records a path as created only on first write, not on
  overwrite of an existing file.
- After a headless run completes, exec.go checks git status for any
  created file still present and untracked, and surfaces a warning via
  the existing writer.warning() (works across text/-o json/stream-json).
  No files are deleted automatically — a wrong guess at 'scratch' could
  destroy real work, so this only surfaces what git already knows.

euxaristia 041167a272 Fix OpenGateway credential lookup, stream error code mapping, and model catalog (#580)
* 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.

* fix(auth): persist OpenRouter API key after login

zero auth openrouter minted a key but only printed it, leaving the
provider unusable unless the user manually exported it or edited
config by hand. Now the key is saved into the credential store, the
provider profile is created/activated, and stale inline/env key
fields are cleared. Auth-failure hints also now point at zero setup
and zero auth openrouter instead of the vaguer zero auth.

* fix(auth): sanitize minted key and roll back orphaned credential on save failure

Addresses PR review comments: trim the OpenRouter key right after
login so both the save path and the manual fallback instructions use
the sanitized value, and delete the just-written credential-store
entry if persisting the stored-key marker in config.json fails, so a
partial failure doesn't leave an orphaned secret.

PierrunoYTandCursor d0c4e62cd4 feat(tui): remember recent provider+model selections in /model picker (#568)
* feat(tui): remember recent provider+model selections in /model picker

The /model picker's "Recent" section only ever showed the currently active
model, making it hard to switch back to a previously used provider+model pair
once you've moved on to something else (especially when the same model name
exists across multiple providers). Track a short automatic history of
provider-qualified switches instead: newest first, capped at 5, deduped by
provider+model pair (not model name alone), and selectable across providers
like any other picker row.

Closes Gitlawb/zero#562

Co-authored-by: Cursor <[email protected]>

* chore: gofmt fixes

* fix(tui): restore favorites one-row-per-model semantics in /model picker

Favorites de-dup had switched to the provider+model key, letting the same
favorited model ID surface once per provider. Revert to per-Value de-dup for
Favorites, and skip any model ID already shown under Favorites from Recent
and Catalog so favorited models don't reappear in a second group. Recent and
Catalog still de-dup among themselves by provider+model so cross-provider
rows remain distinct.

Also correct the recordRecentModel doc comment: in-memory history is updated
even without a user config path (only persistence is skipped), not a no-op.

Addresses Copilot review comments on #568.

* fix(tui): set OwnerProvider on registry catalog rows; dedupe recent-model normalization

- registryModelPickerItem now tags rows with OwnerProvider (the registry
  entry's canonical provider), fixing the plain-registry fallback path (no
  saved providers resolved any models) where two providers offering the same
  model id would collide in pickerItemDedupKey and silently drop a row.
- Export config.NormalizeRecentModels and have
  internal/tui/picker.go's normalizeRecentModelEntries delegate to it instead
  of maintaining an independent copy of the same trim/dedupe/cap logic, so the
  TUI and persisted-config normalization can never drift apart.
- Add regression tests for both.

Addresses remaining CodeRabbit review comments on #568.

* fix(tui): batch recent-model persistence into one write per switch; tighten tests

- Add recordRecentModels(pairs...), a batched form of recordRecentModel that
  normalizes and persists exactly once per switch instead of twice (outgoing
  + incoming pair each triggered their own read-modify-write to
  userConfigPath). handleModelCommand and switchProviderModel now call it
  once with both pairs.
- picker_test.go: capture and assert switchProviderModel's status return in
  TestSwitchProviderModelRecordsRecentHistory instead of discarding it, so a
  failed switch fails at the actual point of failure.
- picker_test.go: also assert the persisted config (not just in-memory
  recentModels) after the reorder/dedupe case in
  TestModelCommandRecordsAndPersistsRecentHistory.
- picker_test.go: pin down the surviving Favorites row's OwnerProvider in
  TestAssembleModelPickerItemsFavoritesDedupByModelIDAndHideFromOtherGroups,
  and drop the tautological otherRecent assertion (other-model was never
  added to recent, so it could never fail).
- resolver_test.go: add TestResolveIgnoresProjectOnlyRecentModels, covering
  the case where only project config sets preferences.recentModels and user
  config omits it — resolved value must stay empty.

Addresses remaining CodeRabbit nitpick comments on #568.

* fix(tui): route unresolvable OwnerProvider rows in-place; align recent-history keys

- choosePicker: only treat a picker row as cross-provider when its
  OwnerProvider resolves to an actual saved provider. Registry-fallback
  catalog rows (tagged with a provider *kind* string) and stale "Recent"
  rows referencing a since-removed provider now fall back to an in-place
  model switch instead of erroring "unknown provider".
- handleModelCommand/switchProviderModel: capture and record recent-history
  entries using m.providerName (the resolved value recentModelPairsForPicker
  pins the active row with) instead of the raw, possibly-empty provider
  profile Name, so a no-name provider profile can no longer produce a
  duplicate "Recent" row for the same switch.
- newModelPicker: scope the registry-fallback's active-model exclusion by
  provider too, consistent with the provider-aware de-dup used elsewhere.
- recentModelPairsForPicker: delegate to config.NormalizeRecentModels
  instead of reimplementing the same trim/dedup/cap logic.
- Remove the unused recordRecentModel wrapper.
- assembleModelPickerItems: build Favorites from recent/catalog directly
  instead of allocating a concatenated copy of both slices.

PierrunoYTandClaude Sonnet 5 302f58bb5f fix(mcp): silence startup warning for unconfigured default servers (#563)
* fix(mcp): silence startup warning for unconfigured default servers

Firecrawl is seeded as an always-on default MCP server with no
credentials (config.DefaultMCPServers), so every fresh install prints
a loud "warning: MCP server firecrawl unavailable, skipped: ... HTTP
401" line on first launch, even though the user never configured or
touched it.

Add config.IsUnconfiguredDefault to detect a server whose resolved
config is byte-identical to its built-in default, thread it through
mcp.Server and mcp.SkippedServer, and skip the startup warning in
app.go when a skipped server is an untouched default. Servers the
user actually configured still warn loudly on failure.

Fixes #552

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

* fix(mcp): address review feedback on #563

- mergeMCPServer now marks disabledSet on the merged config whenever a
  disabled toggle was explicitly applied, so an explicit re-enable
  (e.g. `zero mcp enable firecrawl`) is no longer indistinguishable
  from an untouched default even though the resolved value matches —
  the toggle itself is the "configured" signal for IsUnconfiguredDefault.
- Tighten TestRegisterToolsFlagsUnconfiguredDefaultOnSkip to assert
  presence in the Skipped() map before checking UnconfiguredDefault,
  so a missing entry fails loudly instead of comparing zero values.

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

* fix(config): close IsUnconfiguredDefault gap for redeclared default values

IsUnconfiguredDefault compared the resolved MCPServerConfig against
DefaultMCPServers() with reflect.DeepEqual. A user who explicitly
redeclares a default's exact field values in their config JSON (e.g.
copying firecrawl's default type/url verbatim, perhaps intending to add
credentials later) produced a resolved value byte-identical to the
default, so the comparison silently treated a real, deliberate config
entry as "unconfigured" — the same trap the disabled/enabled toggle
case was already patched for, just left open for every other field.

Add an unexported `configured` field to MCPServerConfig, set whenever
MCPServerConfig.UnmarshalJSON actually runs for a server key (built-in
defaults are seeded as Go struct literals and never unmarshaled, so
they start unconfigured). IsUnconfiguredDefault now requires both
!configured and the value still matching the default — the value check
remains as a fallback for callers that construct MCPServerConfig
directly rather than through the JSON/merge pipeline, where configured
is always false.

This also lets mergeMCPServer drop the disabledSet-specific
"mark as touched" workaround added for the toggle case, since
`configured` now generalizes it.

Adds TestResolveMCPExplicitRedeclareOfDefaultValuesIsNotUnconfiguredDefault
covering the redeclared-values case.

ba99fa8d48 fix(provider): stop dropping custom no-auth providers on restart (#558)
* fix(provider): stop dropping custom no-auth providers on restart

Custom OpenAI/Anthropic-compatible catalog entries hardcode
RequiresAuth as a template default for the setup wizard, not a fact
about the user's actual endpoint. Leaving the credential step blank
(e.g. a local llama.cpp server) still stamped the saved profile with
a guessed OPENAI_API_KEY/ANTHROPIC_API_KEY env var, and that same
static RequiresAuth flag then made the profile look like it was
missing a required credential on the next run, silently filtering it
out of /model.

Add a Custom flag to the catalog descriptor so both the wizard
(write side) and setupMissingCredentialEnv (read side) judge these
profiles by their own explicit APIKeyEnv instead of the catalog's
static default.

Fixes #555

* fix(provider): self-heal legacy custom profiles stamped by the old wizard bug

CodeRabbit flagged that profiles saved before this fix could already
carry the phantom APIKeyEnv the old wizard stamped on every custom
provider (e.g. OPENAI_API_KEY), and the new custom-branch logic would
keep treating any non-empty APIKeyEnv as an explicit requirement —
leaving already-affected users' providers filtered out of /model even
after upgrading.

Treat an APIKeyEnv that exactly matches the catalog's own guessed
default as indistinguishable from unset, so already-broken saved
profiles self-heal without a config.json migration. A deliberately
different env var name (e.g. via --api-key-env) still means auth is
required.

Co-authored-by: Pierre Bruno <[email protected]>

* fix(provider): centralize custom-endpoint credential logic, fix two more surfaces

Copilot's review of the earlier fix found the same RequiresAuth-as-
authoritative bug in two more places that decide whether a saved
provider needs a credential:

- validateProviderRuntimeReady (zero providers check) would hard-error
  a no-auth custom endpoint with "requires API key".
- providerWizardCredentialLabel and providerCredentialRequired (/providers
  status, wizard summary) would still claim/warn that one was needed.

Added config.ProviderProfile.MissingCredentialEnv as the single source
of truth for this decision (custom-endpoint self-heal included), and
had setupMissingCredentialEnv and validateProviderRuntimeReady delegate
to it. providerWizardCredentialLabel and providerCredentialRequired
take the same Custom-aware fix directly, since their non-catalog
fallback path uses runtime-resolved provider-kind metadata that
shouldn't be collapsed into the canonical helper.

Anandan 87158a1c90 feat: voice dictation (speech-to-text) (#557)
* ## Speech-to-text dictation

Adds voice dictation to Zero. Run `/voice` to enter hold-to-record mode, then hold **Space** to dictate and release to transcribe (run `/voice` again to turn it off so Space types normally). Pick a backend with `/stt-model`.

### Backends
- **Local (sherpa-onnx)** — offline, no API key. Auto-downloads a model via `/stt-model`; the engine binary is fetched once and shared across models. Family auto-detection covers the mainstream offline families (Whisper, transducer/Zipformer, Moonshine, Paraformer, SenseVoice, and the CTC families FireRedASR, NeMo, TeleSpeech, WeNet, Zipformer-CTC, Dolphin, Omnilingual — plus the encoder/decoder families Canary and FireRedASR-AED).
- **Cloud batch** — Groq and OpenAI Whisper. Keys resolve from a configured provider, the encrypted credential store, or the env var; a missing/invalid key is entered inline.
- **Streaming** — a warm local sherpa-onnx websocket server (live transcript as you speak) on desktop, or Deepgram / OpenAI Realtime.

### Highlights
- Live audio-reactive waveform while recording (real mic levels when streaming; a synthesized wave for batch).
- `/stt-model` download chooser: recommended models first, Live/Batch tag per row, size + download state, and a search filter.
- Streaming transcript is inserted live into the composer and committed on stop; batch inserts on stop. Insert-for-review by default (`stt.autoSubmit` to fire straight at the agent).
- The warm streaming server is released when `/voice` is turned off and on exit.

### Implementation notes
- No CGO and no bundled runtimes — every OS integration shells out via `exec.Command` with discrete argv (never a shell string).
- The streaming server manager mirrors the LSP manager's warm-subprocess lifecycle.
- OS-boundary code (recorders, transcribers, server) is unit-tested via injected fakes; real microphone / websocket behavior is covered by env-gated smoke tests.

### Testing
- `go build ./...`, `go vet ./...`, and the config / dictation / cli / tui suites pass.
- Verified end-to-end against real downloaded binaries + models (offline batch, streaming websocket server, and the model auto-download), including the FireRedASR-CTC and NeMo streaming transducer families.

* fix(dictation): harden recorder.Stop, Esc-cancel priority, streaming region

Three correctness issues from PR review:

1) recorder.Stop() panicked (nil-deref) when called on a StartStreaming
   session because StartStreaming intentionally leaves r.proc nil. Reject
   that misuse with a clear error. Termux's batch path also leaves
   r.proc nil by design — keep that path working.

2) Esc was consumed by an active dictation session before the
   confirming second Esc could cancel a pending run, so a user
   mid-recording who double-Esc's to kill the run found the first Esc
   swallowed by dictation. Gate dictation-cancel on the Esc not being
   a pending-run confirm.

3) applyStreamingText hard-reset the cursor to regionStart on every
   partial, yanking focus away from users editing elsewhere in the
   composer, and stored regionStart/End as absolute indices that became
   stale the moment the user typed or pasted before the live region.
   Preserve the cursor when it's outside the region, and snapshot the
   prefix BEFORE the region so the next partial can detect external
   edits and shift [start,end) to stay aligned.

Kevin Codex 16550569c1 feat(providers): OAuth login profiles and list-first /provider manager (#560)
* feat(providers): OAuth login profiles and list-first /provider manager

Make multiple providers a first-class workflow: every OAuth login is now a
visible, switchable provider, and /provider manages the whole lifecycle.

OAuth logins become provider profiles:
- zero auth chatgpt / zero auth login <preset> and all four TUI login paths
  (wizard + first-run, browser + device-code) now upsert a catalog-backed
  profile via config.EnsureCatalogProvider after storing the token — without
  stealing the active provider. Previously the token was stored invisibly:
  the provider showed up nowhere and 'providers use' failed not-found.
- Switching to an OAuth provider no longer inlines the bearer as an API key,
  which suppressed the runtime resolver (no token refresh, no Codex
  chatgpt-account-id header → guaranteed 401s). The credential gate now
  recognizes stored OAuth logins on keyless profiles.
- providers list / current report truthful credential state: stored keys
  count as configured (APIKeySet honors apiKeyStored) and token logins show
  'oauth login'; providers check accepts an OAuth login as a credential.

List-first /provider manager (TUI):
- /provider opens the saved-provider list: Enter activates via the shared
  switch path, 'a' adds (existing wizard), 'e' opens a field-level editor
  (endpoint, model, key, description, and safe rename — the stored key,
  activeProvider, and live ZERO_PROVIDER follow the new name), 'd' deletes
  with an inline confirm and stored-key cleanup. Esc walks back one level.
- Credential states resolve asynchronously so keychain reads never block
  the render loop; 'stored key missing' surfaces broken keychain entries.
- Implemented as manager steps on providerWizardState so every existing
  overlay gate, key route, and mouse hook covers it unchanged.

CLI + config parity:
- zero providers remove <name> (deletes the stored key, hands the active
  pointer off) and zero providers rename <old> <new>.
- config.RemoveProvider / RenameProvider: read-modify-atomic-write; rename
  migrates the credential-store entry write-new-then-delete-old so an
  interruption can never lose the key.

* fix(providers): address PR #560 review findings

All six review findings validated as real; fixes with regression tests:

- Persist the apiKeyStored marker when a key is captured onto an existing
  profile: mergeProfile deliberately ignores the marker (a project config
  must not claim the user's stored keys at resolve time), so the user-config
  WRITE path (UpsertProvider) now re-applies it — previously editing a key
  onto an env/no-key profile stranded the secret in the credential store
  while every ApplyStoredAPIKey gate skipped it. [jatmn P2]
- Let active-pointer recovery select OAuth-login providers:
  firstUsableProvider now applies the same providerHasOAuthLogin check as
  setupRequired/usableSavedProviders, so a stale activeProvider plus a saved
  ChatGPT/xAI login recovers instead of forcing onboarding. [jatmn P2]
- Delete stored keys from the store BESIDE the config being edited:
  providers remove and the TUI manager delete now use ProviderKeyStoreAt
  (matching setup/rename) instead of the default-path store. [jatmn P2]
- Roll back the key migration when RenameProvider's config write fails, so
  the store and config.json can't desync (key under the new name, config
  still naming the old one). [CodeRabbit]
- Clear provider descriptions for real: new SetProviderDescription writes
  the field verbatim (the upsert merge treats empty as unchanged); the
  manager's editor routes description changes through it. [jatmn P3]
- Surface stored-key deletion failures in providers remove (stderr warning
  + keyError in the JSON payload) and the TUI delete status, instead of
  letting a lingering secret read as a clean removal. [CodeRabbit]

* fix(providers): second review round — case-only rename, logout hint, test hermeticity

- Skip the credential-store migration on case-only renames (groq -> Groq):
  the store normalizes names case-insensitively, so Set(new)+Delete(old)
  target ONE entry and the delete removed the key that was just "moved".
  The existing entry already serves the new name. [CodeRabbit]
- Point the delete flow's cleanup hint at the stored login that actually
  exists: after a rename ({name:"codex", catalogID:"chatgpt"}) the token
  lives under the catalog id, and `zero auth logout codex` would delete
  nothing. oauthLoginName resolves the same FirstStored candidate the
  runtime uses. [jatmn P3]
- Lock in APIKeyEnv semantics after a key edit: the env reference survives
  as an explicit override (a SET env var wins at resolve time; the stored
  key applies when it is absent). [CodeRabbit nitpick]
- Make main's new firstUsableProvider tests hermetic: they read the REAL
  OAuth token store, so any developer with an actual xai/chatgpt login gets
  spurious failures (found because this machine has one).

Also rebased onto main; the only conflict was comment wording in
firstUsableProvider, where the audit commit (#481) independently landed the
same OAuth-login fallback check this branch added.

* fix(tui): read stored keys from the active config's credential store

The TUI's write paths (SecureProviderProfile capture, rename migration,
manager delete) all target the store beside m.userConfigPath, but the read
paths still opened the DEFAULT-path store: profileWithCredential (feeding
the /model and manager switch gate), the model picker's discovery
credential lookup, and the manager's async credential-status probe. With a
non-default config path, a provider saved with only apiKeyStored had its
key in the config-adjacent store, so the gate rejected it as having no
usable credential and the manager showed 'stored key missing' for a
healthy profile.

All TUI stored-key reads now resolve through providerKeyStoreForPath
(config-adjacent, default-path fallback for ephemeral sessions), so the UI
reads from the same store it writes to. Regression test covers both the
credential probe and the switch path with a key seeded only beside the
config.

Also consolidates the OAuth test-store seeding on withAuthStore (now pins
ZERO_OAUTH_STORAGE=file so an inherited keyring backend can't bypass the
temp path) per review nitpick.

* fix(providers): resolve self-review findings — atomic edits, key normalization, threading

Findings from a multi-agent code review of this branch (8 finder angles,
independently verified); all confirmed against the code, several with
empirical repros.

Correctness:
- config.EditProvider: one atomic read-modify-write for the manager's Save
  (rename + fields + verbatim description + stored-key marker + key
  migration with write-failure rollback). Replaces the rename→upsert→
  describe sequence that (a) turned a case-only rename (groq → Groq) into a
  DUPLICATE profile via UpsertProvider's case-sensitive merge, and (b) could
  fail halfway, leaving config.json renamed while savedProviders and
  ZERO_PROVIDER still held the old name (retry then failed 'not found').
  A rename now also migrates a freshly captured replacement key (captured
  under the current name; the migration moves it).
- savedProviders is mutated surgically on manager delete/edit instead of
  being replaced with the raw user-config list — the session list is seeded
  from the RESOLVED (project-config layered) and usability-FILTERED set, so
  wholesale replacement dropped project-contributed providers and
  resurrected filtered stubs for the rest of the session.
- oauth.ProviderKey normalizes provider names to lower case at the single
  write/lookup choke point: `zero auth login xAI` stored provider:xAI while
  every candidate lookup was case-sensitive — a successful login invisible
  to the runtime. Map-based presence checks lowercase to match.
- OAuth login persistence moved onto the Update goroutine (message handlers)
  — a background tea.Cmd (device-code polls land minutes later) doing an
  unlocked config read-modify-write raced UI-thread writes (lost updates).
  The write error is now surfaced and the in-memory mirror is skipped on
  failure, so a profile that never reached disk can't show as a working
  provider that vanishes on restart.

UX / consistency:
- Esc inside a manager-launched add flow walks back to the provider list
  from EVERY step (was: first step only; deeper steps destroyed the overlay
  and the user's place). In-flight OAuth logins are invalidated on the way
  out; footers say 'Esc back'.
- switchProviderModel returns a structured outcome; the manager branches on
  it instead of strings.Contains(text, "Switched to") — UI copy is no longer
  a control-flow contract (a provider named 'Switched to prod' could close
  the manager on a refusal).
- Manager delete's keychain subprocess + OAuth lookup run in a follow-up
  tea.Cmd (the confirm keypress no longer blocks the render loop); the
  credential probe takes ONE token-store snapshot instead of 2 reads per
  row, and resolved states carry over across reloads (no 'checking…' flash).
- Credential-state reporting converges: /provider status recognizes OAuth
  logins (was 'api key: not set' + warning for a WORKING provider), doctor
  uses the shared HasConfiguredCredential definition plus OAuth awareness
  (its 'matching ProviderSnapshot.APIKeySet' claim is true again), and the
  manager's classifier falls through a stale stored-key marker to env/OAuth
  the way the runtime does.

* fix: address bugs found in a multi-agent codebase audit

Five parallel review agents each swept a different area (self-update,
TUI keybindings, agent/session handling, sandbox/shell safety, and
auth/credential storage) and surfaced nine concrete defects, all fixed
here with regression tests:

- sandbox: grant_scope path comparisons were case-sensitive, letting a
  persisted deny grant be bypassed by spelling a Windows path with
  different case
- securefile/oauth: createSecretFile's Windows ERROR_ACCESS_DENIED
  handling was only applied to the oauth token store, not the shared
  credstore backend; both also masked the real lock-contention error
  behind a misleading "file does not exist" timeout
- cli: firstUsableProvider ignored OAuth logins when picking a
  fallback provider, forcing unnecessary re-onboarding for an
  already-authenticated user
- sessions: exec prompt summarization truncated on a raw byte offset,
  which could split a multi-byte UTF-8 rune and embed invalid UTF-8
  into a resumed session's prompt
- tui: configurable keybindings had no collision detection, so a
  remapped chord could silently make a hardcoded shortcut (or another
  configured binding) permanently unreachable
- tools: the Windows shell-syntax pre-flight check wasn't quote-aware
  and could block harmless commands whose quoted arguments merely
  contained operator-like text
- update: checksum verification didn't cross-check the archive
  filename it verified against the one being extracted; extractZip
  didn't reject symlink-mode entries like extractTarGz already did;
  replaceBinary's restore-on-failure rename had no retry, risking a
  permanently missing binary on a transient Windows file lock

* fix(tools): drop stale ; test case after rebasing onto main's MSYS check

Rebasing fix/bug-hunt-findings onto main pulled in #476, which replaced
this file's regex-based windows_shell_syntax detection with a
segment/word-anchored check and deliberately stopped treating ; as a
command separator on Windows (cmd.exe doesn't split on ; the way bash
does). detectShellCommandIssue itself came out of the rebase unchanged
from main (our quote-masking version was fully superseded by #476's
more thorough segment-based approach), but the quoted-content test
this PR added still asserted the old bash-style semantics for
`echo "foo" ; ls -la`, which now correctly returns no issue since it's
a single echo invocation with literal arguments under cmd.exe, not a
real ls invocation.

Kevin Codex 95ccd5bc32 perf: universal tool-output ceiling with spill + async post-edit diagnostics (#518)
* feat(tools): universal token-based output ceiling with spill-to-disk

Cap every tool result at the registry boundary (16k estimated tokens,
ZERO_TOOL_OUTPUT_CEILING_TOKENS-tunable, 0 disables) unless the tool
manages its own deliberate budget. Head+tail truncation, full output
spilled to the existing redacted spill dir and re-readable via
grep/read_file, so nothing is lost — only deferred.

This closes the three unbounded paths a single call could flood the
context window through (and then re-bill every following turn):
- web_fetch: up to 256KiB default / 2MiB max of non-HTML body
- skill: full SKILL.md returned uncapped
- MCP-served tools: no budget at all

Self-budgeting tools opt out via an unexported marker interface (an MCP
server can never exempt itself): bash, exec_command (model-raisable),
read_file, read_minified_file, grep, glob, list_directory. Browser
snapshots deliberately stay under the net.

bash itself is tightened to match the unified token model: emit budget
96KiB -> 32KiB per stream (~24k -> ~8k tokens worst case per stream),
while capture retention stays at 96KiB head+tail so the new spill file
covers 6x more of the output than the transcript shows.

* perf(agent): collect post-edit LSP diagnostics off the tool-call path

Inline post-edit diagnostics blocked every edit_file/write_file result on
the language server: a >=300ms quiet-period debounce that reset on each
publish, seconds on the first edit per language, capped at 10s — the
largest recurring latency tax in an edit-heavy session.

Diagnostics are now collected in the background: a file is enqueued the
moment a mutating tool finishes, a single worker checks it while the rest
of the batch executes, and the loop drains completed results just before
building the NEXT provider request, appending errors as a user nudge.
The model always issues another request after an edit turn (to read its
tool results), so it still sees introduced errors at the same decision
point — no tool call ever stalls on the language server.

A file re-edited before its check runs is checked once in its final
state (the checker re-reads the file); re-edited after, it is re-queued
and the newer result wins. A drain that finds the worker still busy
gives up after 3s and delivers on a later turn — results stay accurate
because any further edit re-enqueues the file.

The tools-side inline mechanism (tools.RunOptions.Diagnostics) is kept
for direct API callers; the loop just no longer wires it.

* fix: address review — max-turns diagnostics drain, capture-gap marker, test hardening

- Drain background diagnostics before the max-turns final-answer request
  so an error introduced by the LAST turn's edit is reported in the
  summary instead of silently dropped (+ regression test).
- spillBashStreams marks the head/tail junction with a capture-gap
  marker when boundedBuffer dropped the middle of a stream, so a spilled
  log never reads as contiguous when it is not; junction position is
  asserted in the test.
- Tests override TMP/TEMP alongside TMPDIR (os.TempDir reads TMP/TEMP on
  Windows) via a shared setTestTempDir helper.
- TestBudgetBashCaptureReportsTrueTotal now asserts spill_path meta and
  spill file content; exemption-list test gains read_minified_file.

* fix(test): use a real workspace root in async diagnostics tests

filepath.IsAbs("/ws") is false on Windows (no drive letter), so the
collector test's workspace-absolute assertion failed on the windows
smoke job. Root the fake workspace at t.TempDir() — absolute on every
platform — and assert against it.

* fix: pattern-scrub spill files and gate finalization on pending diagnostics

Review follow-ups (Vasanthdev2004):

- Spill files now pass the pattern-based secret scanner (AWS keys,
  GitHub/Slack/OpenAI tokens, PEM blocks, JWTs) in addition to the
  configured-key scrub. A bash spill runs before formatBashOutput's
  scan, so without this a spilled file held in cleartext exactly the
  credentials the transcript redacts. Applied centrally in
  spillTruncatedOutput, covering bash, exec_command, and ceiling spills.

- Finalization diagnostics gate: a no-tool-call final answer now drains
  pending post-edit diagnostics with the full inline-era budget (10s,
  vs the 3s per-turn wait) before the run is accepted; introduced
  errors append the nudge and give the model one more turn instead of
  being silently dropped when no later turn exists. The max-turns
  summary path uses the same finalization budget. Free for runs that
  never edited — an idle collector returns immediately.

KRATOS 284a6c86cb Skills: deterministic invocation — /<skill-name>, searchable /skills picker, discovery-budget fix (#520)
* feat(skills): make skill invocation deterministic and discoverable

Skills were model-pulled only: the model had to notice a skill in a
640-byte system-prompt list (~6 skills visible; the rest collapsed into
'…and N more') and call the skill tool on its own. Users could not run a
skill at all — typing /<skill-name> reported 'unknown command'. The two
halves of the fix:

User invocation
- /<skill-name> [args] now runs an installed skill directly: resolved
  after builtins and user commands, the skill body is inlined as the
  prompt with the typed args appended, and submitted through the same
  launch path user commands use.
- /skills lists installed skills with their slash form, live from disk.
  Labels are honest: a skill shadowed by a builtin, alias, user command,
  or a case-colliding sibling is listed bare with a '(via skill tool)'
  note instead of advertising a dead /name.
- The slash palette suggests skills (labeled '(skill)') read through the
  same loader dispatch uses, so mid-session installs appear and shadowed
  or case-colliding names are never advertised.
- Skill and user-command invocations now apply the plain-prompt run-state
  guards: mid-run submissions queue the EXPANDED prompt (the queue flush
  submits literal text), compaction-in-flight warns, exiting drops.
- Skills resolve through a lazy plugin-aware loader (default dir merged
  with plugin skill roots — the same set the skill tool and the system
  prompt see), TTL-cached so palette keystrokes don't re-read SKILL.md
  bodies.

Model triggering
- Raise the skills-list budget 640 -> 4096 bytes: the list is the model's
  only discovery surface, and the old cap made skills past ~6 invisible —
  invocation reliability collapsed exactly for users invested in skills.
- Raise description truncation 100 -> 200 runes: the description carries
  the trigger conditions ('use when…'); cutting them is what stopped the
  model from firing the skill.
- Strengthen the instruction line: scan the list before acting, call the
  matching skill FIRST, don't substitute your own approach.

* feat(tui): /skills opens a searchable skill picker

Replace the static /skills card with the same picker UX /model uses:
type-to-filter (ranked search), arrow-key selection, Enter runs the
chosen skill immediately. Selection is by the skill's exact name, so
skills the slash path cannot reach — names shadowed by a builtin or
user command, or names that don't fit a slash token — are still
runnable from the picker, where the choice is unambiguous. The text
card remains only as the no-skills install hint, and the picker path
applies the same run-state guards as slash invocation.

* feat(tui): ask-first guard for bare skill invocations

A skill invoked with no request submits only its body — instructions
with no target ("review the PR" — which PR?) — and the model improvises
a target instead of asking, which is especially wrong in a fresh
session. Bare invocations (slash and picker) now append a conditional
note: if the instructions need a target or details not already clear
from the conversation, ask first; self-contained skills still just run.
Invocations that carry a request are unchanged.

* fix(tui): review follow-ups — restore typed invocation on compaction guard, cap merged suggestions

- The compaction-in-flight guard for skill/user-command invocations fired
  after the dispatch path had already cleared the composer, so the typed
  "/name args" was lost and had to be retyped; thread the raw invocation
  through and restore it into the composer (the plain-prompt guard keeps
  the composer intact by firing before the clear). The picker path has no
  typed form and restores nothing.
- Cap the merged autocomplete list at the shared bound: each source
  self-caps, but three sources could stack to ~3x the palette limit.
- Tighten the shadowed-skill palette test to assert on the advertised
  Name rather than the fallback Desc wording.

* chore: ignore zero-skills local build artifact

A locally built test binary under this name was accidentally committed
(and has been scrubbed from the branch history); ignore the name so it
cannot recur.

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.
