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

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

Four changes, each independently safe:

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

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

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

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

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

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

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

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

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

Review follow-ups for #532:

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

1ec7219aee feat: use Exa as default search provider (#926)
* feat: use Exa as default search provider

Amp-Thread-ID: https://ampcode.com/threads/T-01a01522-a5f1-7139-8a55-5e417cba2751
Co-authored-by: Amp <[email protected]>

* fix(config): carry a legacy default's disable across the Exa migration

A user who ran `zero mcp disable firecrawl` chose not to open that outbound
connection. Renaming the built-in default to exa re-opened it under the new
name on upgrade, and because the replacement looked like an untouched default
the startup warning stayed quiet too.

Carry an explicit user-level disable of a retired default onto its successor,
but only when the user never declared the successor themselves — an explicit
exa entry wins either way. The carried-over disable is recorded as a user-level
decision, so the lower-trust project layer cannot lift it while
`zero mcp enable exa` still can.

Regression coverage: the legacy-disabled upgrade path, the explicit-exa
override, a configured-but-enabled legacy entry, the CLI re-enable, the
project-layer re-enable attempt, and the resulting startup behavior
(NormalizeConfig must not hand back an exa server to connect to).

Co-Authored-By: Claude Opus 5 (1M context) <[email protected]>

* fix(config): keep a retired default's transport for partial user entries

A user who added an API key to the firecrawl default wrote only the header —
the seeded default supplied the http type and URL. Once the default stops being
seeded that entry resolves with no type, url, or command, and NormalizeConfig
rejects it, taking down startup for every other server too rather than just
that one.

Record what Zero used to ship for a retired default and re-seed it under the
user's own fields. Only for an entry that named no transport of its own: an
entry with a self-hosted url or a stdio command is a complete definition the
user owns, and grafting the retired http default onto a command produces a
server that is rejected outright.

Regression coverage at both ResolveMCP and NormalizeConfig for the header-only
entry and its failure path, the self-hosted stdio entry that must be left
alone, and a disabled retired entry keeping a usable transport so a later
re-enable resolves.

d065467cd3 feat(zerogit): auto-create a conventional branch before push/pr on default branch (#671)
* feat(zerogit): auto-create a conventional branch before push/pr on default branch

zero changes push/pr refused to push straight to the default branch but
never offered an alternative, unlike other agent tooling that names and
checks out a feature branch automatically. Add CreateBranch, IsDefaultBranch,
CurrentGitUser, and branch-name slugify/build helpers to zerogit, and wire
push/pr to auto-create a "<user>/<slug>" branch (slug from an LLM when a
provider is configured, otherwise a deterministic fallback from the diff)
whenever the current branch is the default one and --yes/--dry-run weren't
passed.

* fix(zerogit): normalize LLM branch slugs, bound remote lookup, handle existing branches

Address CodeRabbit's review on the auto-branch-naming PR:

- generateAutoBranchSlug now takes the first non-empty, quote-trimmed
  line of the model's response before slugifying, instead of folding
  any preamble or wrapping quotes into the branch name.
- isDefaultBranch's ls-remote lookup is now bounded by a 5s timeout so
  a slow or unreachable remote can't stall push/pr; falls back to the
  local main/master heuristic as before.
- CreateBranch checks whether the target branch already exists locally
  and checks it out instead of failing checkout -b on the collision.

Also add regression coverage: CurrentGitUser's OS-username fallback
tier, CreateBranch's existing-branch and generic checkout-failure
paths, a CLI-level test for changes pr (previously untested) mirroring
the existing changes push coverage, and a messy-LLM-response case for
the slug normalization fix.

* fix(zerogit,cli): make auto-branching collision-safe, remote-aware, fail-closed, and opt-in for LLM naming

- CreateBranch never checks out an existing branch on a name collision: it
  picks a unique suffixed name off the current HEAD (name-2 .. name-9) and
  fails visibly when the namespace is exhausted, so a stale branch with
  unrelated history can no longer be published while the new commit stays
  behind on the default branch.
- ensureFeatureBranch resolves the remote once (explicit --remote, then the
  original branch's configured upstream, then origin) via IsDefaultBranch,
  which now reports the resolved remote, and push/pr thread that remote into
  Push, so a freshly created branch without tracking configuration no longer
  falls back to origin in fork setups.
- The default-branch check fails closed: main and master count as default
  with no network, an unreachable remote falls back to the local
  refs/remotes/<remote>/HEAD record, and when neither answers the push is
  refused with guidance instead of silently dropping the confirmation guard
  for repositories whose default is trunk or develop.
- LLM branch naming is now opt-in via --auto on push/pr, matching commit
  --auto: a configured provider alone no longer causes the change diff to be
  uploaded during ordinary git-only pushes.
- After the ordinary commit-then-push sequence the tree is clean, so the
  fallback name comes from the HEAD commit subject instead of the constant
  user/changes.

* style(zerogit): align fake-runner result comments to gofmt output

* test(zerogit): cover Push's fail-closed path when the default branch is unknown

* fix(zerogit): keep a stale cached remote HEAD from clearing the push guard

When the live ls-remote default-branch lookup fails, isDefaultBranch fell
back to the local refs/remotes/<remote>/HEAD cache and returned
branch == cachedName. That cache is only a hint: if the server renamed its
default (main -> trunk) the record still names main, so checking whether
pushing trunk is safe returned false and the newly protected branch was
pushed without --yes.

Trust the cache only to block a push (a positive match proves the branch is
the recorded default); on a mismatch fall through to the existing
fail-closed unknown-default error instead of treating the branch as
unprotected.

* fix(cli): honor --diff-bytes when inspecting the diff for auto-branch naming

changes push/pr accept and document --diff-bytes, but ensureFeatureBranch
inspected the working tree with only Cwd set. With --auto the resulting
unbounded diff was embedded in the branch-name request to the provider, so a
user who capped the diff to limit how much proprietary source is uploaded
for naming still sent the complete diff.

Thread options.maxDiffBytes through ensureFeatureBranch into InspectOptions,
matching how the commit path already bounds the diff.

* fix(cli): refuse an auto-branch push when HEAD has nothing to publish

The auto-branch path decided to branch solely from working-tree status and
never checked that HEAD was ahead of the default branch. On a clean,
up-to-date default branch it would create and push user/<subject> at the
exact default tip; with only uncommitted edits it named a branch from those
edits but pushed the unchanged HEAD, leaving the edits local, and changes pr
then abandoned the empty branch before the host rejected the comparison.

Add zerogit.CommitsAhead and consult it before branching: when HEAD is
provably not ahead of <remote>/<default>, report "no changes to publish"
instead of creating the branch. An indeterminate count (for example a
remote-tracking ref that was never fetched) is treated as "cannot tell" so a
legitimate first push is not blocked.

* fix(cli): recover the branch slug from preamble or fenced LLM replies

The slug helper returned the first non-empty line verbatim, so a reply like
"Here is a suggested branch name:\nadd-login-page" produced
user/here-is-a-suggested-branch-name, and a reply wrapped in a code fence
slugified the ``` line to nothing and silently fell back to the local name.

Drop Markdown code-fence lines and prefer a line that already reads as a
kebab-case slug, falling back to the first quoted/plain line only when no
slug-shaped line exists. Cover preamble and fenced responses with tests.

* fix(zerogit): harden auto-branch remote handling

Three review findings:

- isDefaultBranch passed the remote to ls-remote before the HEAD
  positional with no --, so a remote value shaped like an option
  (--upload-pack=/bin/echo) was parsed as one. Terminate options with --
  and cover a dash-prefixed remote.

- An unborn remote (freshly created, zero refs) answered ls-remote with
  empty output, fell through to the fail-closed unknown-default error,
  and made the very first feature-branch push a --yes dead end that
  git remote set-head --auto cannot repair. ls-remote succeeding with no
  refs now counts as proof there is no protected default; main/master
  stay guarded by the name heuristic and every failure path stays
  fail-closed.

- CreateBranch probed only local refs/heads for collisions, so a branch
  existing only on the target remote (an old merged-PR branch) was
  silently fast-forwarded by the later push -u. The target remote's
  heads are now probed once (bounded, with --) and count as taken;
  an unreachable remote fails visibly before anything is created.

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

* fix(zerogit): close branch-naming and push safety gaps from review

Require a confirmed unborn HEAD, not just an empty ls-remote --symref,
before granting the first-push exception, since a dangling remote
HEAD looked the same. Resolve branch naming and ahead-count checks
against the remote branch instead of a working-tree snapshot, which
could describe uncommitted edits a commit-only push would never
publish. Guard concurrent branch creation with a force-with-lease
push. Scope the ls-remote timeout to the default-branch preflight
only, so it no longer caps Push's own unrelated check.

* fix(cli): require a clean tree before auto-branch push/pr

Refuse ensureFeatureBranch when the working tree is dirty or the
ahead count against the remote default cannot be determined, so a
default-branch push cannot leave uncommitted edits behind or publish
an empty comparison under a guessed name.

* fix(zerogit): drop fixed five-second remote lookup timeout

IsDefaultBranch and CreateBranch applied a hard 5s bound on ls-remote,
so ordinary feature-branch pushes and the collision probe failed on slow
but reachable remotes (SSH/VPN) before Push could run. Honor the
caller's context instead; callers that need a bound pass a deadline.

* fix(cli): bypass the ahead-count and diff-base checks on a confirmed-unborn remote

jatmn flagged that the confirmed-unborn-remote exception this PR added to
IsDefaultBranch never actually helps the main/master case it was written
for: when the local branch is named main, isDefaultBranch returns true from
the name heuristic before it ever consults the remote, so
ensureFeatureBranch still unconditionally calls commitsAhead against
<remote>/<branch>. On a genuinely empty remote that ref cannot exist, so
`zero changes push`/`pr` from a local default branch against a brand-new
empty remote still dead-ended with "cannot determine whether HEAD is
ahead of origin/main" - the exact bug this PR set out to fix.

Tracing the flow further, the same problem also hit the diff-base Inspect
call right after: it uses the same nonexistent <remote>/<branch> ref, so
bypassing only commitsAhead would have left the dead end one line later.

ensureFeatureBranch now probes the new zerogit.IsUnbornRemote (ls-remote
--heads on the remote) whenever commitsAhead fails, and only bypasses both
checks when that probe positively confirms the remote has no refs at all.
An unreachable remote, or one that answers with refs, still fails closed
exactly as before - the fail-closed "unknown default branch" behavior is
unchanged and covered by TestEnsureFeatureBranchFailsWhenAheadCountUnknown
and the new TestEnsureFeatureBranchFailsWhenUnbornCheckErrors.

TestEnsureFeatureBranchCreatesBranchOnConfirmedUnbornRemote is the
regression test: confirmed failing (with the exact dead-end error) against
the pre-fix logic, passing after.

* fix(zerogit): resolve main/master against the live remote default first

isDefaultBranch short-circuited on the literal branch names main/master
before ever consulting the remote. A repository whose remote default is
genuinely something else (e.g. trunk) could still have a local main branch
tracking that remote, and the shortcut wrongly treated it as protected
instead of trusting the live symref result. The conventional-name check
now only applies as a last-resort fallback, after both the live ls-remote
symref lookup and the local remotes/<remote>/HEAD cache fail to answer.

* fix(cli): preserve push lease on retry and check the live default ref

Two related gaps in ensureFeatureBranch's auto-branch preflight:

- When an auto-branch push loses a force-with-lease race against a
  concurrent creator, the generated branch is left checked out locally
  with no successful push behind it. A retry took the "already off the
  default branch" early return and dropped RequireNewRemoteBranch,
  letting the next push silently fast-forward whatever the concurrent
  creator published. The lease now stays required unless the branch
  already has a configured upstream (proof a push already landed).

- The ahead-of-default check compared HEAD against the local
  remote-tracking ref, which is only refreshed at clone or the last
  fetch. A stale ref can under-report how far ahead HEAD is, or say
  zero when the remote has actually moved past it, so ensureFeatureBranch
  now refreshes that tracking ref before trusting it, and fails closed
  if the refresh itself cannot be confirmed.

Adds regression coverage for both: a retry after a lease collision keeps
requiring the lease (and an already-published branch does not), and a
stale tracking ref is refreshed before the ahead check runs (with a
fail-closed case when that refresh cannot be confirmed).

* fix(cli): track generated branches, reject PR on unborn remote, classify main on unborn

* fix(zerogit,cli): preserve explicit nonexistence lease on force, propagate marker write errors, check unborn remote before branch switch

* fix(zerogit): preserve non-existence lease on target remote and roll back failed branch marking

Compare target remote against configured upstream remote to retain non-existence lease on target, roll back created branch if marking fails, and allow --yes to bypass PR default-branch preflight.

Refs #671

* fix(cli): address review findings for auto feature branch creation

* fix(cli): refine LLM preamble candidate slug extraction and enforce unborn-remote guard

* fix(cli): restore default branch after auto-branch and resolve --yes upstream

Do not leave auto-branch commits on the protected local default branch,
and resolve the real upstream for the unborn-remote guard under --yes
instead of always probing origin.

* test(cli): assert auto-branch passes capped diff into the provider

Thread --auto and a mock provider through DiffBytes coverage so the
cap is checked on the real LLM request path, not only Inspect.

* fix(cli): block auto-branch on unborn remotes and fix lease/restore

Refuse auto-creating a feature branch when the target remote has no refs yet.
Publishing only user/slug leaves remote HEAD dangling, so the next changes pr
fails closed and a later main push has no PR diff. Require push --yes first.

Keep the nonexistence lease unless branch@{upstream} is exactly the target
remote/generated-branch ref from a successful push -u. Inherited origin/main
from branch.autoSetupMerge=inherit must not drop the lease.

Restore the original default branch against its own upstream tip, not the
push destination, so --remote upstream does not rewrite a fork main that
tracks origin/main.

* fix(cli): recover push -u upstream and filter LLM slug preambles

Push -u can publish a remote branch then fail to write local upstream
config. Treat that as incomplete, recover with set-upstream-to, and probe
the remote before reasserting the nonexistence lease on retry. Also skip
one-word LLM acknowledgements before accepting a slug-shaped line.

Refs #671

* fix(cli): decide the branch-collision lease with one live remote check

Replace the local-state inference chain (upstream config, a
zeroAutoBranch marker, per-remote provenance tracking) that kept
producing new collision-safety edge cases across many review rounds
with a single live remoteHasBranch check against the destination
remote: missing there gets the nonexistence lease, already there gets
a plain push, and git's own fast-forward check is the safety net if
that existing branch isn't actually ours.

Removes MarkGeneratedBranch/IsGeneratedBranch, now dead, along with
the tests that pinned the specific local-state heuristics rather than
the collision-safety property itself.

* fix(cli,zerogit): address CodeRabbit findings on auto-branch naming

Recover trailing-punctuation LLM slugs, notice deterministic fallback,
report dual restore/rollback failures, and skip Push upstream repair on
dry-run. Align comments with fail-closed and DryRun behavior.

* fix(cli,zerogit): finish ensureFeatureBranch doc contract and close review gaps

The ensureFeatureBranch doc comment ended mid-sentence and sat on the featureBranchOptions type, so go doc attached function prose to the struct.

Also extract the branch slug filename with path.Base because git paths are always slash-separated, gate two tests on the git version their fixtures need (autoSetupMerge=inherit requires 2.35, init --bare -b requires 2.28), and cover the literal "user" CurrentGitUser fallback via a test seam.

Co-Authored-By: cairn-code <[email protected]>

* fix(zerogit): make RemoteHasBranch report existence only, not tip equality

RemoteHasBranch's tip-equality check made ensureFeatureBranch reassert the
nonexistence lease (--force-with-lease=<branch>:) on every push after the
first: a second local commit puts HEAD ahead of the just-published remote
tip, so the check reported false for a branch that plainly exists, and Git
rejected the follow-up push with a stale-info error instead of a normal
fast-forward.

The concurrent-creator race the tip check was meant to guard was already
handled one layer up: ensureFeatureBranch drops to a plain push when the
branch exists and relies on Git's own fast-forward check as the safety net
(see TestRunChangesPushDropsLeaseWhenBranchExistsOnRemote), so a race
survivor with unrelated history is rejected there regardless of tip
equality here.

Add TestRemoteHasBranchReportsTrueForDivergedTip, which fails under the old
tip-equality check and passes now.

Refs #671

* fix(cli,zerogit): preserve the generated branch on a compare-and-swap conflict

After auto-branching, ensureFeatureBranch restores the default branch to its
own upstream tip using the compare-and-swap form of update-ref. When that
refused because the default branch had moved concurrently, the failure was
indistinguishable from an ordinary update-ref write error, so the rollback
path ran and deleted the freshly created feature branch. That branch
exclusively owns the user's commits at that point, so a lost race destroyed
work in order to "recover" from it.

Add ErrCompareAndSwapConflict, returned by ResetBranchRef only when an
expected-old value was supplied (the sole way git refuses is a tip mismatch).
ensureFeatureBranch now recognizes it and returns without rolling back,
reporting that the branch was preserved so the user can reconcile the default
branch by hand.

Extend TestResetBranchRefRefusesConcurrentDefaultAdvance, which already drove
a real concurrent advance, to require the sentinel. Add
TestEnsureFeatureBranchPreservesBranchOnCompareAndSwapConflict, which fails
with "must not delete the generated branch" when the new branch is removed.

* fix(daemon): clean up child after startup timeout

* fix(daemon): terminate startup process tree

* test(background): accept reaped-later zombie children

* fix(background): retain configured process group target

* fix(background): address termination review feedback

* fix(daemon): use launch-time group identity, fix zombie/reap classification

Addresses jatmn's three #774 review findings:

- TerminateCommand rediscovered the process group via
  execution.TerminateProcessTree's Getpgid(pid) lookup. On Darwin,
  that lookup can return ESRCH once an unreaped group leader has
  already exited, even though live descendants remain in the group
  it configured at launch — silently falling back to signalling only
  the (already dead) leader PID and leaving descendants running (the
  required macOS smoke job's failure). Add
  execution.TerminateProcessGroup, which signals the negative PID
  directly using the launch-time Setpgid invariant instead of
  rediscovering it, and route TerminateCommand through it.

- signalTargetRunning's zombie check matched the individual-PID
  fallback target (a process that is not its own group leader)
  against the process table by PGID. That target's actual PGID
  differs from its own PID by definition, so no row ever matched,
  unknown resulted every time, and a zombie individual-PID target
  was always conservatively reported as still running. Branch on the
  sign of the target: group members by PGID, individual PIDs by PID.

- TerminateCommand returned the termination error even when the
  subsequent reap succeeded — a successful cmd.Wait is authoritative
  proof the leader is gone and collected, regardless of how the kill
  attempt itself went (e.g. taskkill /T racing an already-exited PID
  on Windows). Classify a successful reap as success.

All three regression tests are verified to fail against the pre-fix
code (confirmed by temporarily reverting each fix and rerunning).

AnandanandVasanthdev2004 0c1de25a04 Add interactive terminal companions (#887)
* Add terminal companions

* Polish interactive terminal companions

* Fix terminal companion edge cases

* Strengthen terminal companion regression tests

* Preserve config layout when selecting pets

* Handle sparse pet preference layouts

* fix(terminalpet): reset SGR before erasing a sixel companion

On Windows Terminal the companion draws a filled black rectangle over the
interface, and dragging it mangles text under and around it. It looks like a
platform quirk. It is an untested code path that only Windows reaches.

Sixel is the only protocol here that erases by PAINTING CHARACTERS. Kitty hands
the terminal an image id and the placement goes away. A sixel is already in the
cell grid, so clearRenderedImage writes literal spaces over the cells it
occupied. Those spaces are ordinary characters and carry whatever SGR the TUI
last set, and nothing normalised it, so every erase stamped a filled block in
the ambient background. A drag erases and repaints on every pixel, so the block
was continuously refreshed over the UI.

It stayed invisible everywhere else because ghostty, kitty, WezTerm and iTerm
all resolve to the Kitty protocol and delete by id, never reaching this code.
Windows Terminal is the only mainstream terminal that lands on the sixel branch,
which is why testing on Linux and macOS could not have caught it.

The erase now resets SGR before painting, and uses DECSC/DECRC rather than
CSI s/u because only DECSC saves the attributes this clobbers. Restoring them
matters: the erase is emitted mid-frame, between styled writes the TUI has
already begun.

Measured before and after rather than reasoned about. Before:

  \x1b[s\x1b[3;41H      \x1b[4;41H      \x1b[5;41H      \x1b[u

no reset anywhere. After, the reset leads and DECRC closes.

Tests assert the bytes, since bytes are what the terminal sees: SGR is reset
BEFORE the first row is painted rather than merely present somewhere, the erase
still covers every claimed cell so the fix cannot be satisfied by erasing
nothing, and the Kitty path still deletes by id rather than acquiring the
character-painting erase. Verified by mutation: restoring the old sequence fails
the first of those with the exact reported symptom.

Deliberately not fixed here, since both are design calls rather than defects:
the erase rectangle is computed from the app's own cell maths rather than the
terminal's real footprint, and the sixel path has no in-place move, so every
drag pixel is a full erase and repaint where Kitty gets a cheap reposition.

* fix(tui): ask sixel terminals for their cell size and erase what was painted

The companion blanks a row and a column of live interface on Windows Terminal.
The cause is one predicate.

petPixelProtocolSupported gates two unrelated questions that only looked like
one: whether pixel-precise dragging is available, and whether to ask the
terminal for its cell size with CSI 16 t. It answers true for Kitty only, so on
a sixel terminal the request was never sent, the reply never arrived, and
petCellPixelWidth/Height stayed zero for the whole session.

Everything downstream then took its fallback. petImageHeightPixels returned its
blind preferredHeight of 75 pixels instead of the cell-aware branch below it,
and the erase in clearRenderedImage used petImageColumns and petImageRows. Those
constants describe the RESERVED area, not what was painted. Windows Terminal
reports a 20x10 cell, so a 75-pixel sprite covers 4 rows and about 8 columns
while the erase blanked 5 by 9, taking a row and a column of interface with it
on every move. A drag repaints per pixel, so it did that continuously.

Windows Terminal answers CSI 16 t, confirmed by hand: it replies
ESC [6;20;10t. This was never a question of terminal support. Nothing asked.

So the request now goes out for every image protocol, via a predicate separate
from the dragging one, and the sixel footprint is computed from the rendered
pixel height and the reported cell size rather than from the constants. It is
still clamped to the reserved area, because the layout keeps that many cells
clear and the drag clamps to it, so a larger computed footprint would mean
erasing into live interface.

Deliberately NOT widening petPixelProtocolSupported itself: that would enable
pixel-precise dragging on sixel as a side effect, which is a separate feature
decision rather than part of this defect.

Kitty is untouched and a test pins that. There Columns and Rows are the
placement REQUEST handed to the terminal, which owns the region and scales into
it, so recomputing them would resize the image rather than fix an erase.

Tests use the real 20x10 measurement: the sixel footprint is 4 rows not 5, Kitty
keeps its requested placement, the fallback without metrics stays the reserved
area rather than collapsing to zero and erasing nothing, and every image
protocol asks for the measurement.

ff62f73b7f fix(secrets,worktrees): fix secret redaction leakage and prune stale worktrees (#855)
* fix(secrets,worktrees): fix secret redaction leakage and prune stale worktrees

1. Prevent trailing redaction leaks in github_token, aws_access_key_id, and google_api_key by adding trailing word boundaries and allowing variable lengths. Refine the openai_key pattern to cleanly distinguish legacy keys and modern prefixed keys (sk-proj-, sk-svcacct-) from ordinary kebab-case phrases.
2. Implement auto-pruning of zero-owned git worktrees older than 24 hours at the start of worktrees.Prepare to prevent indefinite disk space leaks.

* fix(secrets,worktrees): close tail-leak edge case and worktree data-loss risk

Drop the trailing \b anchor on the four secret patterns whose body
class allows "-" (slack_token, google_api_key, the modern openai_key
branch, jwt). \b requires a word/non-word transition, so a secret
ending in "-" right before a delimiter has none, and the engine
backtracked the greedy quantifier to drop that last character instead
of failing the match, leaking it. The body character class already
provides the real stopping boundary, so the anchor was unnecessary.

Fix two issues in worktree Clean flagged in review:

- Staleness was decided by the worktree directory's own mtime, which
  only changes when an entry is added/removed/renamed directly inside
  it, not when a long-running task edits existing files deeper in the
  tree. Clean now walks the tree and treats any recently modified entry
  as live, and also skips any worktree a caller has explicitly locked
  via git worktree lock.
- baseDir ownership used a raw strings.HasPrefix, so a sibling like
  "<baseDir>-other" would false-match. Replaced with a filepath.Rel
  path-boundary check.

* fix(worktrees): check exit codes on removal, fail closed on inspection errors

defaultRunGit deliberately returns a nil error alongside a nonzero
CommandResult.ExitCode for a failed git invocation, so the worktree
remove call must check ExitCode itself instead of trusting a nil error
to mean success. Route it through gitOutput, which already does that.

worktreeIsStale treated an inspection failure (an unreadable file, a
WalkDir error) the same as "keep walking," which can let an
incompletely-inspected worktree be judged stale. Any inspection error
now makes it ineligible for removal instead.

* fix(secrets,worktrees): catch appended-suffix keys and scope pruning to owned worktrees

The scanner's trailing \b anchors made a credential vanish entirely when
followed by a word character outside its body class (an appended suffix
like AKIA...EXTRA, or ghp_..._suffix): the fixed or unbounded-greedy
quantifier had no valid word boundary to land on and the whole match
failed, so the real secret reached the redaction output unredacted.
Dropping the trailing anchors lets the body class itself stop the match,
so the credential prefix still gets redacted even when noise follows it.
Also recognize sk-admin- alongside sk-proj-/sk-svcacct- so OpenAI admin
keys aren't skipped by the narrowed modern-key branch.

Clean pruned any worktree under the caller-supplied BaseDir, but Prepare
only ever creates worktrees under a per-repository
zero-worktree-<repoKey> subtree of it. Scope pruning to that subtree so a
worktree a user manages by hand elsewhere under a shared BaseDir is never
force-removed. Also refuse to force-remove a worktree whose mtime looks
stale but that still has uncommitted or untracked changes: a task can
hold live work while waiting on a model, network, or user for longer
than the staleness window without writing to the tree again.

* fix(worktrees): make nested-activity test exercise the deep walk it claims to

activePath/internal was created by the same MkdirAll as the nested pkg
dir but never backdated, so it kept a fresh mtime and worktreeIsStale's
walk reported "not stale" as soon as it hit that directory, before ever
reaching the freshly-written file two levels deeper. The test passed
without actually exercising recursion past the first directory.

* fix(worktrees): lock zero-created worktrees and treat ignored files as dirty

Prepare never called git worktree lock, so the entry.locked skip in Clean
only ever protected worktrees a human locked by hand, never zero's own; a
worktree that finished committing and sat idle (e.g. waiting on a slow
model or network retry) for more than 24h looked clean-and-stale and got
force-removed by the mtime+dirty heuristic alone. Lock every worktree
Prepare creates so it gets the same protection.

worktreeIsDirty also used git status --porcelain with no --ignored, so a
worktree holding only .gitignore-matched task data (credentials, generated
drafts, artifacts) reported as clean and got force-removed with --force,
silently discarding it. Add --ignored so those files count as dirty too.

* fix(worktrees): release Zero's Prepare lock so Clean can reclaim finished worktrees

Prepare locks every worktree it creates so Clean's mtime+dirty staleness
heuristic never force-removes one Zero is still using, but nothing ever
unlocked it, making the automatic disk-space cleanup permanently inert.

Add Release (git worktree unlock) and wire it in two ways: zero exec
--worktree defers a release once its own run finishes, since that flow's
use of the worktree is bound to its own process. zero worktrees prepare
hands the path to a longer-lived external caller with no defined
end-of-life, so a new zero worktrees release <path> subcommand lets that
caller release it explicitly when done.

* fix(worktrees): normalize release path, aggregate Clean errors, unlock deleted worktrees

Address CodeRabbit's review on the lock-release fix:

- zero worktrees release now resolves its path argument to absolute
  before calling Release, since git worktree unlock matches against
  the path git recorded at creation, not whatever directory the
  caller happens to be running from.
- Clean now aggregates removal failures with errors.Join instead of
  overwriting lastErr, so multiple stale worktrees failing removal in
  the same pass are all reported, not just the last one.
- Release falls back to options.Cwd as the git working directory when
  the worktree path itself no longer exists (e.g. a caller deleted a
  locked worktree by hand instead of releasing it first), so the
  orphaned lock can still be cleared.

Added regression coverage for all three.

* style(worktrees): align aggregation test comments to gofmt output

* fix(worktrees,cli): restore reuse lease and scope unlock to owned locks

- Prepare re-locks a reused worktree so Clean's staleness heuristic cannot
  force-remove it while the new caller is still using it; a lock already
  held by a live external caller is kept in place and reported through the
  new Result.LockAcquired field.
- exec --worktree only releases the lock its own Prepare call acquired and
  surfaces a failed release on stderr with the affected path instead of
  discarding the error.
- worktrees release wires the resolved workspace root into Options.Cwd so
  the deleted-path recovery works outside the worktree directory.
- The relative-path release test derives its expected value via
  filepath.Abs, matching the resolution the CLI uses, so macOS /var vs
  /private/var spellings no longer break it.

* fix(worktrees,cli): reject in-use leases, validate before cleanup, add release -C

- Prepare rejects a worktree whose lock another run still holds, on both
  the reuse and the create-race paths, instead of handing a second live
  caller an unprotected shared checkout whose sole Git lock the first
  caller's exit would release.
- The automatic stale-worktree pruning runs only after the request itself
  validates, so a rejected command (an invalid --name) has no destructive
  cleanup side effect; covered end to end with real git in both directions.
- worktrees release accepts -C/--cwd naming the source repository, which
  the deleted-path recovery needs when launched outside the repo (the
  deleted worktree path is a one-way hash with no way back to its source).

* test(worktrees): canonicalize test roots to physical spelling

git records worktree paths in physical form, so the CI runners' symlinked
(/var -> /private/var) and 8.3-short (RUNNER~1) temp spellings made Clean's
containment check skip the test's stale entry and the pruning assertion
fail on macOS and Windows.

* fix(worktrees): preserve orphaned commits, verify release ownership, canonicalize base dir

Four fixes from the latest review round:

- Clean now creates a durable ref (refs/zero/orphaned-worktree/<sha>)
  for a detached worktree's HEAD before force-removing it, when that
  commit isn't already reachable from any other ref. Prepare always
  creates worktrees with `worktree add --detach`, so a commit made
  there had no ref pointing at it once the worktree was deleted,
  making it immediately eligible for git gc despite never having been
  merged/pushed elsewhere.

- Clean resolves its configured base directory through EvalSymlinks
  before comparing it against git's reported worktree paths: `git
  worktree list --porcelain` reports each worktree's PHYSICAL location
  (resolving symlink components), so a symlinked --worktree-dir made
  every worktree created under it permanently unprunable.

- Release now verifies path has a zero-worktree-<repoKey> ancestor
  directory component before running `git worktree unlock`, so it
  can't be used to clear the lock on a worktree a user or another tool
  manages by hand. The check doesn't need to know which --dir a given
  Prepare call used (nothing records that against a specific worktree,
  and the CLI never threads BaseDir through to Release) — the repoKey
  component is Prepare's actual ownership signature regardless of
  which directory it was created under.

- Route the release command's printed path and exec's release-failure
  diagnostic through the existing CLI redaction helper, and split the
  worktrees help text into prepare-specific and release-specific flag
  sections (release only ever supported -C/--cwd, not the --name/--dir/
  --json the shared block advertised).

All four have regression tests confirmed to fail without their fix
(two using real git worktrees, not just fakeRunner sequences). Build,
vet, and gofmt clean on linux/windows/darwin.

* fix(worktrees): recoverable PID leases and reclaimable released worktrees

Two review findings on the cleanup lifecycle:

- A lock left by an abnormal exit (SIGKILL, crash, power loss) was
  skipped by Clean forever, recreating the permanent disk leak this PR
  set out to fix. exec --worktree now records its PID in the lease
  reason; Clean expires a lease whose recorded owner is provably dead,
  unlocking only after the staleness, dirty, and HEAD-preservation
  guards all pass. Human locks and PID-less leases (external
  `worktrees prepare` owners) remain permanent until explicit release,
  and any ambiguity in the liveness probe counts as alive.

- An explicitly released worktree holding only gitignored residue
  (node_modules, build output) was skipped at every age. Release is the
  owner's completion signal, so unlocked entries now block removal only
  on tracked/untracked changes; expired crashed leases keep the
  conservative --ignored probe since they never signaled completion.

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

* fix(worktrees): address review feedback on lease detection and release safety

Split dead-lease PID checking into posix/windows implementations so
Windows can reliably tell a dead process from a live one. Fix a path
canonicalization mismatch in two release tests. Derive release
ownership from git worktree list instead of the git-dir parent, which
was wrong for repos with a separate git-dir. Refuse to clear a lock
that was not taken by Zero in the first place.

* fix(worktrees): canonicalize paths for clean/release ownership checks

Compare Clean containment and Release ownership against physical path
spellings so macOS /var vs /private/var and symlink TMPDIR layouts match
git worktree list. Require a registered porcelain entry and a Zero lease
reason before unlock; treat an already-unlocked Zero worktree as a no-op.

* fix(worktrees,secrets): address jatmn review findings on #632

- Prepare and Release now agree on repoKey regardless of which worktree
  (main or linked) Prepare runs from, by keying off git worktree list's
  first entry (always the main worktree) instead of --show-toplevel.
  A worktree prepared from a linked checkout previously failed its own
  ownership check on release and its lease could never be cleared.
- osProcessAlive on Windows no longer treats every OpenProcess failure
  as "process is dead": only ERROR_ACCESS_DENIED (a live process this
  caller lacks rights to query) is now distinguished from a genuinely
  missing PID, so Clean can no longer force-remove an active worktree
  whose owning process it simply couldn't query.
- The openai_key redaction pattern now recognizes sk-or-v1- (OpenRouter)
  alongside the existing sk-proj-/sk-svcacct-/sk-admin- prefixes, so
  hyphenated OpenAI-compatible provider keys are redacted again without
  reopening the sk-<kebab-case-phrase> false-positive this pattern was
  narrowed to avoid.
- Release/exec --worktree error text is redacted before reaching
  stderr, matching the already-redacted success path; ownership errors
  interpolate the caller-supplied path, which could carry a key-shaped
  segment.
- canonicalizePath resolves symlinks through the nearest existing
  ancestor when the target itself no longer exists, so the documented
  `release -C` recovery path works again for a worktree deleted by hand
  under a symlinked --worktree-dir.
- Prepare rolls back the worktree `git worktree add` just created if the
  subsequent lock call fails for a reason other than a concurrent
  racer, instead of leaking an unleased checkout until Clean's 24h
  staleness window reclaims it.

Not addressed here: the P2 finding that worktree ownership is provable
only by a directory-name convention plus a lock-reason prefix, both of
which a user can reproduce by hand. A durable per-worktree ownership
marker would close that gap, but internal/worktrees has been on main
since #70, so a marker requirement could reject worktrees an
already-installed zero created before this change existed. Needs a
decision on migration before implementing.

* fix(worktrees): prove Prepare ownership with a git-admin marker

Address review findings that path convention plus lease-reason prefix are
forgeable by hand. Prepare now writes a zero-owner marker into the worktree
admin dir; Release and Clean require it before force-touching a path. Clean
also keys its owned subtree off the main worktree root so linked-checkout
calls still prune the same bucket Prepare uses. Tests plant the marker and
list the main worktree first so fixtures match production.

* fix(cli): complete worktrees release in shell completions

* test(worktrees,cli): add coverage for linked-worktree Clean, forged lease rejection, and completions

- TestCleanFromLinkedWorktreePrunesStaleWorktree: pins Clean deriving its
  owned-subtree key from the main worktree root (not the invoking linked
  checkout's --show-toplevel) so Prepare/Clean run from a linked worktree
  actually reclaim the worktrees Prepare created there.
- TestReleaseRejectsForgedZeroLeaseWithoutOwnershipMarker: pins the
  ownership-marker requirement against the exact forgery jatmn described - a
  worktree under the predictable zero-worktree-<repoKey> path, manually
  locked with a reason that merely starts with the zero lease prefix.
- Fix TestPrepareCreatesDetachedGitWorktree: its fake git runner ran out of
  canned results at Prepare's post-lock ownership-marker write, so
  writeOwnershipMarker resolved gitDir to "" and os.WriteFile wrote
  "zero-owner" as a relative path into the test process's real working
  directory instead of failing loudly. Give it autoAbsoluteGitDir like the
  other Prepare-exercising tests use and assert on the marker-write call.
- completions_test.go: assert `worktrees`/`worktree` completions include
  `release` alongside `prepare`.

* fix(secrets): add bash output redaction regression test for Anthropic API keys

* fix(worktrees): touch worktree mtime on reuse to prevent stale pruning

When Prepare reuses an existing worktree, it now touches the directory
to refresh its mtime. This prevents Clean from force-removing a
long-running but idle worktree (e.g. waiting on a model) that has no
recent file changes but is still actively in use.

Addresses the data-loss risk flagged in the PR review where mtime-only
staleness + --force removal could discard live worktrees.

0176ee49ff feat(agent): add PermissionModePlan for interactive read-only planning (#853)
* feat(agent): add PermissionModePlan for interactive read-only planning

* fix(agent): drop redundant modeName branch, add plan mode regression tests

string(permissionMode) already yields "plan" / "spec-draft", so the
if/else recomputing modeName in the denial message was dead branching
on the same values. Also add plan-mode coverage mirroring three of the
four existing spec-draft regression tests: advertised tool set, and
denied write_file/bash calls. The fourth (submit-and-stop review
control) has no plan-mode analog, since plan mode has no submit tool.

* fix(agent): deny request_permissions in plan/spec-draft even when the registry omits it

request_permissions is dispatched by name in executeToolCall before the
registry-based ToolAdvertised gate runs, so that gate only helps when
the tool happens to be present in the caller's registry. A plan- or
spec-draft-mode registry that simply omits the tool (rather than
registering it as denied) let the call fall through to a real
turn/session-scoped permission grant, defeating the read-only
boundary. Deny it unconditionally at the top of
executeRequestPermissions for both read-only modes instead.

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

* fix(agent): suppress executable hooks while plan/spec-draft mode is active

Plan mode promises a read-only turn, but sessionStart/sessionEnd fire on
every run and beforeTool/afterTool fire around allowed read calls, and
all four execute configured host commands outside the advertised-tool
and sandbox gates — so a project hook could mutate the workspace or
spawn a process from a session that advertises it cannot. Gate all four
dispatch points on the run's permission mode, with a regression test
asserting no hook command launches during a plan-mode run.

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

* fix(agent): close plan-mode tool advertisement bypass

toolAdvertisedInPlan whitelisted ask_user and update_plan by name
alone, so a caller could register a mutating tool under either name
and have it advertised and executed in plan mode. Validate every tool
against its Safety() instead. Also exclude lsp_navigate, which is
marked SideEffectRead but lazily spawns a real language-server
process, contradicting plan mode's read-only guarantee. Add
regression tests for both.

* fix(agent): keep trust-gated hooks in spec-draft mode

Plan mode still suppresses executable hooks so a read-only planning turn
cannot spawn host processes via session or tool hooks. Spec-draft keeps
the existing trust model: project hooks fire when the workspace (or its
worktree trust root) is trusted. Unconditionally suppressing hooks in
spec-draft broke TestExecSpecWorktreeInheritsTrustEndToEnd for trusted
worktrees under --use-spec --worktree.

* fix(agent): cover plan-mode spoof and lsp_navigate denials

Expand the name-only spoof regression to both update_plan and ask_user,
and add an execution-path denial for lsp_navigate so plan mode cannot
spawn language servers even when a call still arrives.

* fix(agent): filter tool_search deferred candidates by plan/spec-draft visibility

tool_search resolved and ranked deferred tools by EnabledTools/DisabledTools
only, never by the run's permission-mode visibility. tool_search itself is
already denied at dispatch in plan/spec-draft (its Safety carries no side
effect, so it fails the same SideEffect==Read advertisement gate direct calls
use), so this was not reachable through the normal Run() path today. But it
is a real landmine: if that outer gate is ever loosened independently (e.g.
tool_search's no-side-effect Safety is judged advertisable), the loader had
no gate of its own and would hand a deferred write/mutator tool's name,
description, and full schema straight to a plan/spec-draft model.

Mirror agent.ToolAdvertised's plan/spec-draft branches inside the tools
package (toolAdvertisedForPermissionMode, next to the existing
toolAllowedByFilters mirror that avoids the same import cycle) and apply it
alongside the operator filters in visibleDeferredTools and
visibleEagerToolNames.

Added unit tests in tool_search_test.go for both modes, and an end-to-end
agent test that force-calls tool_search in plan mode and asserts no schema
leaks. Verified by reverting tool_search.go and confirming the new tests fail
(one shows load_tools resolving to the mutator's name); restored and
confirmed they pass. Also confirmed via a temporary probe that if plan mode's
outer advertisement gate is loosened, this filter is what actually stops the
leak.

* fix(agent): require Safety for spec-draft ask_user/submit_spec

Do not advertise or load re-registered control tools by name alone in
spec-draft mode. ask_user must be SideEffectRead+Allow and submit_spec
must be SideEffectWrite+Allow, matching the real tools. Apply the same
filter in tool_search and add spoof regression tests.

Refs Gitlawb/zero#642

* fix(agent): wire plan mode into TUI, CLI, and ACP entry points

Address the P1 finding that PermissionModePlan was documented but never
selected by /plan, zero exec, or ACP mode selectors. /plan on|off now
toggles the session permission mode (restoring the prior mode on off),
zero exec --plan selects plan for a run, and ACP advertises plan as a
client-selectable mode. Integration coverage for each entry path.

* fix(cli): reject --plan combined with --worktree

Worktree preparation runs in runExec before the plan permission mode is
assigned, so `zero exec --plan --worktree` could still trigger workspace
mutation ahead of the read-only gate. Reject the combination during
option validation, alongside the existing --use-spec/--skip-permissions-
unsafe conflict checks, so no worktree prep can occur.

* test(tools): assert spoofed tool schema doesn't leak via tool_search

The spoofed-control-tool regression only asserted on the description
string; Parameters() exposed no distinctive schema marker, so a
regression that leaked the schema without the description would still
have passed. Add a spoofed_secret property to the test tool's schema
and assert it's absent from result.Output alongside the description.

/plan on only flips the agent permission mode, which gates agent tool
calls. Local TUI commands that run entirely inside the TUI process
bypass that gate: /rewind restores workspace files from a checkpoint,
/export writes a transcript to disk, and /sandbox-setup spawns a
native host process. Add a shared plan-mode guard at the start of
dispatchCommand (mirroring the existing BTW-unavailable guard) that
rejects these three commands while permissionMode is
agent.PermissionModePlan, with regression coverage proving each is
blocked with no mutation/process spawn in plan mode and unaffected
outside it.

* fix: prevent leaking sensitive info in wrapped error responses

Modified `fmt.Errorf` calls in `internal/cli/trust.go` to use `%s` instead of `%w` when wrapping errors that are subsequently redacted via `redaction.ErrorMessage()`. This ensures the underlying error is flattened to a plain string, preventing sensitive information from being exposed later via `errors.Unwrap()`.

* chore(cli): drop agent sentinel from trust error-format tidy

Remove .jules/sentinel.md (local agent artifact, not in main). Keep the
trust.go %s flatten as a readability tidy only; redaction.ErrorMessage
already stringifies inline, so this is not a security fix.

* style(cli): note intentional %s flatten on trust resolve errors

Keep a short comment at both sites so the %s form is not "fixed" back to %w; ErrorMessage stringifies inline.

30f6d8f591 fix(specialist): make overwrites atomic (#757)
* fix(specialist): make overwrites atomic

* fix(specialist): harden atomic replacement

* fix(specialist): replace through a Windows-atomic, DACL-preserving primitive

Addresses both P1 findings on #757.

os.Rename — which fsutil.RenameWithRetry wraps — is documented non-atomic
outside Unix, and the retry loop only handles sharing violations. Worse, the
replacement is a freshly created temporary file, so renaming it over the
destination also publishes the directory's inherited DACL in place of the
destination's own: overwriting a specialist that had been explicitly restricted
inside a group-readable directory would expose its system prompt to that group.
temp.Chmod(0o600) cannot prevent that on Windows, where Go maps only the
owner-write bit.

New fsutil.ReplaceWithRetry publishes through a platform primitive:

- Windows uses ReplaceFileW with REPLACEFILE_WRITE_THROUGH, one operation that
  carries the replaced file's security descriptor, attributes, and streams over
  to the replacement. REPLACEFILE_IGNORE_ACL_ERRORS is deliberately not passed —
  silently losing the descriptor is the failure being fixed — so a merge failure
  surfaces and leaves the destination untouched. A missing destination falls back
  to a rename (nothing to replace or preserve), as do volumes that cannot perform
  a replace at all (FAT/exFAT, some network redirectors), which carry no ACL
  either. The transient-lock retry is unchanged.
- Unix keeps rename(2), which is already atomic within one filesystem.

Tests: Windows coverage asserts the destination's creation time survives (a
rename would not, proving the call goes through ReplaceFileW) and that a
protected owner-only DACL survives both at the fsutil layer and through the real
`Create --force` path; a plain rename was verified to replace that DACL with the
directory's inherited ACEs, so the assertion has teeth. POSIX covers both
destination shapes.

* fix(fsutil): stop ignoring ACL merge errors, recover partial ReplaceFileW

Addresses jatmn's two #757 review findings:

- The call passed REPLACEFILE_IGNORE_MERGE_ERRORS (0x2) while the
  comment claimed ACL failures were fail-closed. Microsoft documents
  0x2 and REPLACEFILE_IGNORE_ACL_ERRORS (0x4) identically: with
  either set, a call lacking WRITE_DAC "succeeds but the ACLs are not
  preserved". Passing 0x2 therefore let a --force overwrite silently
  publish the temp file's inherited directory DACL over a restricted
  specialist and expose its system prompt. Pass no flags at all.

- With no backup file, ERROR_UNABLE_TO_MOVE_REPLACEMENT (1176) and
  ERROR_UNABLE_TO_MOVE_REPLACEMENT_2 (1177) leave the destination
  deleted (1176) or renamed to an unreachable name (1177) while the
  replacement survives only under its temporary name. Returning those
  unrepaired let the caller's deferred temp-file cleanup remove the
  sole surviving copy, so one failed 'specialist create --force'
  destroyed both the old manifest and the new one. recoverPartialReplace
  now moves the replacement into place and still reports the error,
  since the destination's descriptor died with the destination.

Also drops the doc claim that REPLACEFILE_WRITE_THROUGH (0x1) flushes
before returning: Microsoft documents that value as "not supported".

The two fsutil regression tests are verified to fail against the
pre-fix code. The specialist-side test guards the caller half of the
recovery contract and does not fail pre-fix; its comment says so.

* docs(specialist): describe what a failed overwrite actually leaves behind

The Windows partial-replace recovery errors told an operator the replacement
"remains at" the caller's temporary path, but the only caller removes that file
in a deferred cleanup before the error ever surfaces — it named a file that was
already gone. Recovery from a failed overwrite is always about the original, so
the errors now describe only what the replace itself left on disk: the state of
the destination and of the managed backup. The replacement path is no longer a
parameter, since nothing reports it.

The one terminal state that needs a human — 1177 whose rollback exhausted its
retries — now says so outright. The original then exists only under an opaque
.zero-replace-*.backup name, and the loader reads *.md, so the specialist stays
invisible until somebody moves it back. The error names both paths and the
action; docs/SPECIALISTS.md walks through it; and loadDirectory records why the
non-.md siblings an interrupted overwrite can leave are skipped rather than
guessed at.

55fa05f0ab fix(sandbox): deny reads of Zero credential stores (#681)
* fix(sandbox): deny reads of zero credential stores

* fix(sandbox): address PR review comments

- Deny reads of mcp-oauth-tokens.json.secret in the default Zero
  config candidates: file-backed oauth stores keep their encryption
  secret in a sibling .secret file, so the default MCP token store
  needs the same protection as the override paths (CodeRabbit).
- Clarify that explicit credential-file overrides are still filtered
  by on-disk existence like every other candidate (Copilot).
- Align the zeroUserConfigDir doc comment with config.UserConfigDir:
  macOS honors XDG_CONFIG_HOME before falling back to ~/.config
  (Copilot).

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

* fix(sandbox): deny the whole Zero config dir, not itemized filenames

Address code review on PR #681:

- Deny credentialDenyReadPaths' Zero-config candidate as the containing
  directory instead of an itemized filename list. The token/credential/
  config stores each publish through a randomly-named .tmp-<pid>-<nanos>
  sibling before their atomic rename, and the legacy MCP token store
  leaves a mcp-oauth-tokens.json.migrated backup after importing it —
  none of those names were covered by the old itemized list, so a
  sandboxed command could read them under the read-all posture.

- Stop dropping default candidates that don't exist yet at profile-build
  time. A store created later in a long-lived sandboxed session (e.g. a
  concurrent ) previously got no deny rule at all; every
  backend already treats a deny rule over a not-yet-existing path as a
  harmless no-op that still takes effect once the path appears.

- Resolve ZERO_OAUTH_TOKENS_PATH / ZERO_MCP_OAUTH_TOKENS_PATH overrides
  the same way the token stores resolve them (relative-to-cwd, no ~
  expansion) instead of through normalizeProfilePath, which tilde-expands
  and so could derive a deny path different from where the store actually
  writes.

Adds regression coverage for the directory-wide deny (including the
migrated backup and synthetic temp-file siblings), for building the
profile before the store directory exists, and for the tilde-override
resolution mismatch.

* fix(sandbox): address macOS deny-path test and config parity

* fix(sandbox): protect OAuth lock siblings

* docs(sandbox): clarify Linux future-path limits

* test(sandbox): probe credential store reads in the Linux smoke test

The smoke test wired HOME/XDG_CONFIG_HOME at credential directories but never
attempted a read through the sandbox, so it could not catch a real-bwrap
regression for the paths this change protects. Write a secret into ~/.aws and
$XDG_CONFIG_HOME/zero and add both to the deny-read table.

* fix(sandbox): keep the credential deny usable, current, and unguessable

Four problems with the credential deny baseline, all in the same mechanism.

The whole-directory deny over $XDG_CONFIG_HOME/zero also hid the supported
user plugin, specialist, and command roots, whose commands and scripts are
executed through this sandbox, so an installed user plugin could no longer
start. Narrowing the deny to itemized files was not an option: the stores
publish through temporary names and a concurrent login can add a store that
did not exist when the profile was built, and only a directory rule covers
both. The directory deny therefore stays, and the non-secret subtrees are
carved back out through a new DenyReadCarveouts field: seatbelt re-allows
them after the deny (SBPL is last-match-wins) plus ancestor metadata so path
resolution can reach them, and bubblewrap masks the directory with --perms
111 instead of 000 -- unlistable but traversable -- and re-binds the carveout
read-only before the tmpfs is remounted read-only.

A relative ZERO_OAUTH_TOKENS_PATH, ZERO_MCP_OAUTH_TOKENS_PATH, or
XDG_CONFIG_HOME was resolved against the command directory only, while
oauth.ResolveStorePath and mcp.ResolveTokenStorePath call filepath.Abs, i.e.
resolve against the Zero process working directory. A command run from a
subdirectory therefore had the wrong path denied and the real store stayed
readable under the read-all posture. Relative candidates now resolve against
both directories, since the process that resolves the value is not
necessarily the one that writes the store. The regression test runs the
command from a different directory than the process, which the previous
tests did not.

bubblewrap cannot mount over a path that is absent when the namespace is
assembled, so a store created mid-session stayed readable through the live
read-only host-root bind for the rest of a long-lived sandbox session. The
directories Zero owns -- its config directory and the per-store publication
directories -- are now reported as EnsureDenyReadDirs and created (0700)
before the namespace is assembled, so their mask always exists. Third-party
stores such as ~/.aws are still skipped when absent: Zero must not create
them, and that limitation stays documented on the field.

The fixed <store>.tmp publication sibling made the plaintext token, and via
the same path its encryption key, observable to a same-user sandboxed process
with write access to an override parent: it could wait for the known name and
rename the opened inode into an allowed path. Both stores now publish through
a per-store <store>.publish directory with a randomly-named file inside. The
directory name is derived from the store path, so the profile can deny it up
front, while the random name inside is what cannot be waited for or renamed
away. A test keeps the duplicated suffix in step with oauth.PublicationDirSuffix.

Also adds the seatbelt render coverage that was missing: dropping
DenyReadIfExists from denyReadRules made every credential store readable
again on macOS without failing a single test.

* fix(sandbox): close credential deny review gaps

Preserve process credential roots alongside command overrides while limiting host precreation and read carveouts to trusted process-derived paths.

Canonicalize future credential roots through existing path aliases, reject symlink carveouts, and collapse automatic masks already covered by user or automatic directory denies. Normalize the policy golden and add regression coverage across profile, Seatbelt, and bubblewrap rendering.

* fix(update): keep the upgrade recommendation about this machine

`zero update --check --target windows-x64` answers a question about a different
machine, but the new call to action told the user to run `zero upgrade`, which
only ever installs onto this one — replacing the target-specific download
guidance the flag used to print. The recommendation is now conditional: a
current-platform check keeps it, and a cross-target check gets the manual
instruction plus a note naming the machine `zero upgrade` would have touched
instead.

Also align two flag contracts with what the code does: `zero update --help`
described --repo/--endpoint as check-only although apply honors them, and
UPDATE.md did not mention that both are ignored on an npm-managed apply, which
takes its release from the npm registry rather than GitHub.

Co-Authored-By: Claude Opus 5 (1M context) <[email protected]>

* fix(update): do not send a custom-source check to the default source

`zero upgrade` is a fresh invocation: it does not inherit the --repo/--endpoint
of the check that suggested it, so recommending it bare after a custom-source
check told the user to install from a repository they never asked about. The
check now records the flag it was given and the guidance repeats it, naming
where a bare upgrade would install from instead.

ZERO_UPDATE_RELEASE_URL is deliberately not recorded: every Check reads it from
the environment, including the one inside Apply, so a bare upgrade already
follows it and telling the user to repeat it would be wrong.

Two smaller edges from the same review: a cross-target check on a host with no
published release target no longer ends by describing what `zero upgrade` does
there, since it does not work there at all; and the flag table and help text now
carry the npm caveat the prose bullet already had, so docs and help agree.

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.

* 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.

* 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.

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.
