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. |

fix: address bugs found in a multi-agent codebase audit (#481)
* fix: address bugs found in a multi-agent codebase audit Five parallel review agents each swept a different area (self-update, TUI keybindings, agent/session handling, sandbox/shell safety, and auth/credential storage) and surfaced nine concrete defects, all fixed here with regression tests: - sandbox: grant_scope path comparisons were case-sensitive, letting a persisted deny grant be bypassed by spelling a Windows path with different case - securefile/oauth: createSecretFile's Windows ERROR_ACCESS_DENIED handling was only applied to the oauth token store, not the shared credstore backend; both also masked the real lock-contention error behind a misleading "file does not exist" timeout - cli: firstUsableProvider ignored OAuth logins when picking a fallback provider, forcing unnecessary re-onboarding for an already-authenticated user - sessions: exec prompt summarization truncated on a raw byte offset, which could split a multi-byte UTF-8 rune and embed invalid UTF-8 into a resumed session's prompt - tui: configurable keybindings had no collision detection, so a remapped chord could silently make a hardcoded shortcut (or another configured binding) permanently unreachable - tools: the Windows shell-syntax pre-flight check wasn't quote-aware and could block harmless commands whose quoted arguments merely contained operator-like text - update: checksum verification didn't cross-check the archive filename it verified against the one being extracted; extractZip didn't reject symlink-mode entries like extractTarGz already did; replaceBinary's restore-on-failure rename had no retry, risking a permanently missing binary on a transient Windows file lock * fix: close remaining PR 481 review findings * Potential fix for pull request finding Co-authored-by: Copilot Autofix powered by AI <[email protected]> * fix(tools): drop stale ; test case after rebasing onto main's MSYS check Rebasing fix/bug-hunt-findings onto main pulled in #476, which replaced this file's regex-based windows_shell_syntax detection with a segment/word-anchored check and deliberately stopped treating ; as a command separator on Windows (cmd.exe doesn't split on ; the way bash does). detectShellCommandIssue itself came out of the rebase unchanged from main (our quote-masking version was fully superseded by #476's more thorough segment-based approach), but the quoted-content test this PR added still asserted the old bash-style semantics for `echo "foo" ; ls -la`, which now correctly returns no issue since it's a single echo invocation with literal arguments under cmd.exe, not a real ls invocation. --------- Co-authored-by: Copilot Autofix powered by AI <[email protected]> |

polish: cut per-turn overhead, stabilize cache, add /new (#478)
* polish: cut per-turn overhead, stabilize cache, add /new Context economy - Compaction: preserveLast 8->6, triggerRatio 0.8->0.7 (both copies in sync). - System prompt: kill the "ELABORATE summary" directive; scale summary to the work. Comment discipline moved into the core prompt for all model families (was Anthropic-only); Minimax/DeepSeek/Qwen/etc. now get it. - Token-budget regression test ratchets the fixed per-turn overhead (base prompt + eager tool schemas) using the runtime's own estimator, so silent prompt/schema growth fails CI. Response quality - defaultResponseStyle balanced->concise. Reversible via /style. Tool discovery - <available_skills> block in the system prompt lists installed skills (name + one-line description) so the model loads the right one on the first call instead of guessing and reading the failure. Budget-capped at 640 bytes with an "...and N more" fallback; renders nothing when no skills are installed (byte-identical to prior prompt). Session lifecycle - /new starts a fresh session in place; previous session stays on disk and is named in the confirmation for /resume. Guards against mid-run reset. - /clear now notes that context persists and points to /new. Performance & caching - partitionTools no longer alpha-sorts the whole tools array every turn, which inserted a loaded deferred tool mid-array and shifted the cached prefix on every load. It now builds append-only regions [eager sorted] + [tool_search] + [loaded deferred sorted] so a mid-session load grows the tail instead of busting the eager prefix. Regression test asserts the eager block precedes any loaded tool. - /context now shows cache hit rate (flags low rate over >5 turns as a possible unstable prefix) and rolling average turn latency with time-to-first-token. Both reset on /new. Measured baselines (auto-mode, no workspace): base prompt 3162 tokens, eager tool schemas 2433 across 12 tools. Budget ceilings set ~10% above. Deliberately deferred (need a decision): inverted safety-policy rewrite (sandbox doesn't catch ~half the B-tier rules), core-tool/web_fetch deferral (activation-semantics blocker), aggressive prompt slim. * fix(tui): clear staged attachments + queued message on /new CodeRabbit: startNewSession reset conversation/usage/latency state but not the staged input (pendingImages, pendingImageLabels, pendingDocuments, queuedMessage), which is only consumed at prompt-submit. Without clearing it, the fresh session's first prompt silently inherited the previous session's images/documents/queued text. Test now stages all four and asserts they clear. |

audit fixes: cron lock, accounting race, O(n²) hot paths, /style wiring (#260)
* audit fixes: cron lock, accounting race, O(n^2) hot paths, /style wiring
Fixes five verified findings from a code audit. Two related findings were already
addressed upstream and three need larger/separate work (noted below).
H-1 cron store: cross-process lock for the read-modify-write.
Two schedulers seeing a job due raced the metadata read-modify-write; fireJob
even documented it ("full atomicity needs file locking"). Adds a per-job O_EXCL
lock (mirroring internal/oauth's pattern, stale-reclaim included) and a Mutate
primitive doing the re-read+modify+write atomically. Update/Remove lock too. The
lock is held only for the millisecond RMW, never across a job's exec.
M-5 specialist accounting: close the check-then-append race.
specialistEventExists (unlocked ReadEvents) + a later AppendEvent let two
finishers (TaskOutput poll vs onExit, even cross-process) both pass the check and
write duplicate stop/usage events. Adds sessions.Store.AppendEventUnlessExists
(check + append atomic under the session lock) and routes the stop and usage
paths through it.
M-2 hooks audit: O(1) sequence via tail read.
append re-read and scanned the whole audit log every call to find the max
sequence (O(n^2) over a session). Reads only the file tail now; multi-process
safe (the log is a shared global file), unlike an in-memory counter which would
collide sequences across processes.
M-4 transcript rehydration: O(n^2) -> O(n).
The three resume/rewind/compact rehydration loops called appendTranscriptRow per
event, each re-scanning every existing row for the keyed-row dedup. A bulk
appendTranscriptRowsDedup builds the key set once; semantics are identical.
M-6 /style: actually shape responses.
The TUI /style command stored a style but never threaded it anywhere. Adds
agent.Options.ResponseStyle, a system-prompt directive for concise/explanatory/
review, and wires m.responseStyle through the run. "balanced" is a no-op (prompt
byte-identical to before).
Already addressed upstream (no change):
- M-1 forked-session double-count: Store.Fork already skips EventUsage events,
with a comment naming the exact double-count it prevents.
- M-3 lineage O(N^2): Tree already does a single store.List() scan and indexes
children in memory; no path calls List per node.
Deferred (need larger/separate changes):
- M-7 escalate_model in the TUI needs a ModelSwitcher that builds a provider
mid-run; registering the tool alone yields a tool that errors on call.
- L-1 MCP SSE reconnect is a stream-lifecycle change (low-likelihood after the
8 MiB per-event cap).
- L-2 dead-code removal belongs in a dedicated cleanup sweep.
Tests: per-fix unit tests including concurrency (cron Mutate, sessions
AppendEventUnlessExists) under -race; full go test ./... green.
* fix(windows): treat ERROR_ACCESS_DENIED as lock contention (cron + oauth)
The Windows smoke run failed TestMutateIsAtomicUnderConcurrency with
"...lock: Access is denied" (FireCount 19/20). On Windows a concurrent holder's
os.Remove leaves the lock file in a delete-pending state, so an O_EXCL create
races it with ERROR_ACCESS_DENIED (os.ErrPermission) rather than ErrExist — the
retry loop only treated ErrExist as contention and hard-failed.
Treat os.ErrPermission as contention (retry) in the new cron lock and in the
oauth lock it mirrors (oauth's own concurrent test exposed the same pre-existing
bug under the added load). Unix is unaffected — it returns ErrExist.
* fix: address review — cross-process atomic audit append + AppendRun guard
Addresses the review feedback on this PR.
P1 (blocking): AuditStore.append is now cross-process atomic.
The O(1) tail read observes another process's prior appends, but the read-then-
append was not atomic across processes — two could both read sequence N and write
N+1. Wraps lastSequence()+append in a per-file O_EXCL lock (hooks/lock.go, same
stale-reclaim + Windows ErrPermission handling as cron/oauth); store.mu stays as
the in-process fast path. Adds TestAuditStoreSequenceConcurrent (4 stores x 12
goroutines on one file -> unique dense sequences), which the prior sequential
test could not catch. Walked back the comment that oversold the tail read.
P2: AppendRun no longer resurrects a removed job.
fireJob's AppendRun ran after Mutate released the per-job lock; a Remove in that
window let AppendRun's MkdirAll recreate the dir with an orphaned runs.jsonl.
AppendRun now takes the per-job lock and bails if metadata.json is gone. Adds
TestAppendRunDoesNotResurrectRemovedJob.
P2: lastSequence ReadAt tolerates a short final read.
ReadAt may return io.EOF with n < len(buf) if the file shrank between Stat and
the read; treat EOF as non-fatal and use buf[:n] (matches lastEventSequence).
P3: oauth stale-reclaim no-op removed.
The double os.ReadFile "stale == data" guard compared the file to itself read
twice in a row (always true); staleness is decided by the mtime check, so the
guard is dropped (behavior-preserving).
Tests under -race; cron/hooks/oauth green. A shared filelock helper would DRY the
three near-identical locks — left as a follow-up to avoid churning the
already-green cron/oauth packages here.

sessions: make the events log authoritative for sequencing + fsync checkpoints/rewind (#251)
Two data-integrity gaps in the session store: 1. Sequence numbers were derived from metadata.EventCount, which is persisted AFTER the event line (a separate file). A crash between the two writes left EventCount behind the log, so the next append reused a sequence number -- a duplicate id that mis-targets /rewind (findRewindTarget returns the first match). Now the next sequence is derived from the events log itself (lastEventSequence, an O(1) tail read that ignores a torn trailing partial), so a stale/desynced EventCount can never cause a reused number; it falls back to the metadata count only if the log is unreadable. 2. Checkpoint blobs and rewind restores used plain WriteFile+Rename with no fsync, while session metadata fsyncs the temp file AND the parent dir -- so the /rewind safety net and restored workspace files were not crash-durable. They now go through the same writeFileSync + syncDir barrier (writeFileAtomicSync), preserving the exact-perm chmod on restore. Tests: stale-low metadata -> no duplicate (the reported repro); stale-high -> benign gap; lastEventSequence over empty / multi / torn-tail / large-event logs. |

Improve /resume: interactive session picker + model-generated titles (#224)
* tui: interactive /resume session picker + resume fixes
- /resume (no arg) now opens an interactive picker like /model and /provider:
one row per resumable session showing the title and session id (+ relative
age); arrow to highlight, type to filter, enter to load. /resume <id> and
/resume latest still resolve directly.
- Resume now loads the rehydrated (compaction-aware) event view instead of the
raw log, so a resumed session honors a prior /compact — matching the CLI's
`zero exec --resume` and the in-TUI /compact reload. Falls back to raw on a
rehydrate error.
- The resume summary reports the model/provider the continuation will actually
use (the active ones), noting the session's recorded model/provider when it
differs, instead of implying a switch that doesn't happen.
- Drop the dead, self-contradictory resumeText(arg) branch (it was unreachable
and its hint was circular); resumeText is now the no-session/error fallback.
Tests: session picker opens with title+id rows and hydrates on selection;
resume honors prior compaction (rehydrated, not raw events).
* tui: lead /resume picker rows with a precise timestamp
Same-titled sessions (e.g. the same first prompt run several times) looked like
duplicates because the row showed only the identical title plus a long id that
truncated the age away. Lead each row's label with a precise local timestamp
(HH:MM:SS today, "Jan _2 15:04" earlier this year, else the date) so distinct
sessions are obviously distinct; the full id stays as the right-aligned meta and
is what selection resolves. sessionWhen parses the RFC3339 UpdatedAt.
* tui: hide empty/no-output sessions from the /resume picker
Most of a heavily-retried prompt's sessions are empty failed runs — just the
prompt plus the no-output guardrail stop ("Agent stopped … with no output …"),
with no assistant text and no tool calls. They have nothing to resume and flood
the picker with identical-looking rows. Skip any session with no resumable
content (no tool call/result and no real non-user message) from the picker; they
stay on disk and are never deleted. Adds agent.IsNoProgressStop to recognize the
stop message from a recorded event, and a test that the picker hides an empty
run while keeping a real one.
* feat(tui): model-generated session titles (auto + /retitle backfill)
Sessions were titled from their first user message, so prompts that
started the same way (or empty/failed runs) looked identical in the
/resume picker. Generate a concise, specific title with the active
provider instead.
- sessions.Store.UpdateTitle(id, title): rewrites only Title under the
per-session lock, re-reading the latest metadata first; leaves
UpdatedAt untouched (a retitle is not activity and must not reorder
the resumable list), rejects a blank title, and no-ops an unchanged
one.
- Title generator: a bounded digest of the conversation (user/assistant
text + tool names, per-message and total caps, skipping the no-output
guardrail stop) is sent as a one-shot completion; the response is
cleaned (first content line, quotes/markup/"Title:" label stripped,
word- and rune-capped) before storing.
- Auto-title going forward: after a successful turn, a session still
carrying its default first-message title gets a title in the
background, at most once per session.
- /retitle: backfills existing resumable sessions that still have a
first-message title, one at a time, skipping empty/failed runs and
already-named sessions, with kickoff and completion status lines.
Generation runs off the Update goroutine; failures are non-fatal (the
first-message title simply stays). Adds store + TUI unit tests
(UpdateTitle semantics, digest/cleaning, auto-title one-shot, backfill
candidate selection). gofmt/vet/build(host+linux+windows)/test -race/
staticcheck all green.
* address review: tighten no-progress detection, fix fallback errors + nil guard
Three review findings on the /resume work:
- IsNoProgressStop matched any content CONTAINING the no-output marker
substring (strings.Contains), so a legitimate assistant/tool message that
quoted the marker could be misread as a failed empty run — wrongly hiding a
real session from the /resume picker and skipping its title generation. Now
it requires the full answer structure (prefix + marker + suffix); a quote no
longer matches.
- resumeEvents returned the earlier rehydration error when the raw ReadEvents
fallback itself failed, masking the actual fallback failure. Returns rawErr.
- resumeText dereferenced m.sessionStore unconditionally; a nil store (fallback/
test paths) would panic. Now renders a safe "store unavailable" message.
(newSessionPicker already guarded nil.)
Tests: IsNoProgressStop accepts the real answer and rejects a quoting message /
bare marker / prefix- or suffix-only; resumeText with a nil store returns the
safe message instead of panicking. Full gate green.
* address review (Vasanth): structural no-progress check, retryable auto-title, nil-store guard, deep resume assertion
- guardrails: IsNoProgressStop now matches the exact structure noOutputStopAnswer
emits — prefix + "<int> turns " + marker + " " + suffix — instead of
prefix && contains(marker) && suffix. A genuine message that merely quotes the
marker amid other prose is no longer misclassified as a failed empty run (which
would wrongly hide a real session from /resume and skip its title generation).
Adds the hostile-input regression cases (quoted marker, text between
marker/suffix, non-integer turn count).
- session_title: release the optimistic titledSessions gate when a generation
FAILS (provider error, empty title, store write error) so a later turn or
/retitle can retry; success keeps the one-shot gate. Kept the optimistic mark
(rather than mark-on-success) to preserve the no-double-fire guarantee while a
generation is in flight.
- session_title: guard maybeAutoTitleActiveSession against a nil sessionStore
(the title cmd calls store.UpdateTitle) — mirrors the resume nil-store guards.
- model_test: assert resumed sessionEvents with reflect.DeepEqual against the
rehydrated context, not just slice length, so a reordered/substituted-but-
same-length regression is caught.

Deep-audit remediation + sandbox hardening (batches 1–35) (#189)
* audit batch 1: redact nested secrets fully; count image tokens in compaction estimate
- secrets.Redact: replace longest matches first so a containing PRIVATE KEY
block is redacted before a nested shorter match corrupts its exact string
(audit medium internal/secrets/scanner.go:81) + regression test.
- agent compaction estimateTokens: add a flat per-image token cost so an
image-heavy context trends toward compaction instead of reading as ~0
(audit medium internal/agent/compaction.go:58) + test.
- ledger: re-verify against current main; mark scanner.go:35 and
redaction.go:362 already-fixed-on-main, record this batch's fixes.
* audit batch 2: worktrees defaultRunGit separates stdout/stderr
Capture git stdout and stderr into separate buffers instead of CombinedOutput,
so parsed rev-parse output is not polluted by git warnings and CommandResult.Stderr
carries the real error text (audit medium internal/worktrees/worktrees.go:247) + test.
* audit: re-verify all 87 pending findings against current main
Independent agent per file re-checked each open/partial finding against the
actual current code (the 06-11 ledger was verified on a since-diverged branch),
with an adversarial second pass on every already_fixed verdict. Authoritative
result: 78 genuinely pending (66 still_open + 12 partial); 9 rows were already
fixed on main and are reclassified. Full table in 2026-06-13-reverification.md.
* audit batch 3 (agent): cancellation identity, always-allow w/o sandbox, compaction usage, dedup
- loop.go: check ctx.Err() before collected.Error so a cancelled run returns
context.Canceled (errors.Is holds) instead of a plain stringified error.
- loop.go: 'Always allow' with no sandbox engine now allows THIS call instead of
denying it (persistence is skipped when there's nowhere to persist).
- loop.go: remove a duplicate schema["items"] assignment in propertyToRuntimeMap.
- compaction.go: forward OnUsage (token accounting) through the summarizer while
still omitting OnText, so compaction's token cost is counted in usage/budgets.
- tests for all three behavioral fixes (each fails pre-fix).
* audit batch 4 (cli): list-tools -o json, interrupted -o json terminal, surface session-record failures
- exec --list-tools -o json now emits a JSON tool listing instead of falling
through to the human-readable text (audit medium exec.go:182) + test.
- interrupted run with -o json now emits a terminal error+done on stdout instead
of only printing to stderr, so a JSON consumer sees a clean end (medium exec.go:500) + test.
- execSessionRecorder: surface a latched session-append failure to stderr once at
run end (deferred) instead of silently dropping it (medium exec_sessions.go:114/115) + test.
- left app.go trailing-arg ignore as-is: documented-intentional, TUI has no argv prompt.
* audit batch 5 (zerogit): status -z porcelain (renames + non-ASCII paths); document env-drop on plain Runner
- parseStatus: switch `git status` to `--porcelain -z` and parse the
NUL-delimited form (audit medium zerogit.go:212). Previously the default
--short output was split on newlines, so a rename `R old -> new` was kept as
one bogus path and a non-ASCII/whitespace filename arrived C-quoted+escaped
(e.g. `"caf\303\251.txt"`). The -z form never quotes paths and emits a
rename/copy as `XY <dest>\0<src>`, so we now record the destination verbatim
and consume the source field. + TestParseStatusZHandlesRenamesAndSpecialPaths.
- resolveRunners: document that the plain-Runner EnvRunner adapter intentionally
drops env (audit low zerogit.go:417). The branch is reached only when a caller
supplies a custom Runner without a RunGitEnv — in practice fake-Runner tests.
Production leaves both nil and gets defaultRunGit/defaultRunGitEnv, which honor
GIT_INDEX_FILE, so snapshot-diff isolation holds. Routing env calls to real git
instead would break the fake-Runner test pattern and fix nothing in production.
- update Inspect/Commit mock tests to the -z status format and the new command.
* audit batch 6 (config): reject negative maxTurns; drop dead contract-gap helpers
- FileConfig.UnmarshalJSON now rejects a negative maxTurns instead of letting the
`MaxTurns > 0` merge gates silently drop it and fall back to the default,
hiding the misconfiguration (audit medium resolver.go:136). 0 is left as the
"unset" sentinel (omitempty) and still falls back to the default; the CLI
--max-turns flag continues to reject 0 too since there it is distinguishable
from absent. + TestResolveRejectsNegativeMaxTurns / ...ZeroFallsBackToDefault.
- remove dead config/contracts.go (ContractGap, DefaultContractGaps,
FindContractGapsByMilestone, ContractOwnerRuntime) and its test — referenced
only by that test, never by production (audit low contracts.go:12).
- NOT changed: ResolveMCP intentionally does not run the provider command
(TestResolveMCPDoesNotRunProviderCommand guards this), so the "ZERO_PROVIDER_COMMAND
MCP servers dropped" row is by-design, not a defect.
* audit batch 7 (mcp): bound captured MCP server stderr
connectStdio attached a plain bytes.Buffer as cmd.Stderr that is only ever read
on initialize failure, yet it kept growing for the entire process lifetime as a
long-lived server logged to stderr (audit medium client.go:98). Replace it with
a concurrency-safe boundedBuffer capped at 64 KiB that keeps the head (enough for
init-error diagnostics) and discards the rest, reporting full write lengths so
os/exec never sees a short write. + TestBoundedBufferCapsRetainedBytes.
Left as-is (not defects worth the risk in the MCP client):
- client.go writer.write under client.mu: already designed to release the lock
before the unbounded response wait; the residual concern is a server that stops
draining stdin, an involved async rewrite for a theoretical deadlock.
- readLoop not answering server-initiated requests (ping): responding safely
needs re-locking around the shared writer; no configured server relies on it.
* audit batch 8 (tools/providers): read_file truncation marker; drop dead provider branch
- read_file: when a max_lines cut occurs, append an explicit "[truncated: N more
line(s)... set start_line=X to continue]" marker to the output. Previously only
the Result.Truncated flag was set, which is invisible in the rendered text, so
the model could not distinguish a cut read from a complete one (audit low
read_file.go:89). + TestReadFileToolMarksTruncation.
- providers/factory: simplify `if !explicitProvider || isImplicitOpenAI(...)` to
`if !explicitProvider` and delete the now-unused isImplicitOpenAI. The clause
was dead: explicitProvider==true implies ProviderKind or Provider is set, but
isImplicitOpenAI required both empty, so it could never contribute a case
(audit low factory.go:118). Behavior-preserving; providers tests still green.
* audit batch 9 (sessions): Tree builds from a single List() snapshot (no N+1 disk scans)
Store.Tree recursed via ListChildren per node, and each ListChildren ran a full
store.List() that re-read every metadata.json from disk — O(nodes * total-sessions)
reads for one tree (audit medium lineage.go:140). Snapshot all sessions once, index
children by parent in memory, and recurse over that. Child ordering is factored into
sortChildSessions so ListChildren and Tree stay identical; path-scoped cycle
detection (delete(seen,...)) is preserved. Existing tree/lineage tests still pass.
Left as-is: store.go timestamp() second precision (RFC3339) — switching to
RFC3339Nano would break lexical UpdatedAt ordering against existing second-precision
records ("...00.5Z" sorts before "...00Z"), so it is not a safe one-line change.
* audit batch 10 (specialist): serialize accounting dedup-then-append
recordSpecialistStop and appendSpecialistUsageRollup checked for an existing event
(specialistEventExists → ReadEvents) and then appended under SEPARATE store locks,
so two concurrent finishers — a foreground onExit racing a TaskOutput poll, or a
background reaper — could both pass the dedup check and write duplicate stop/usage
events (audit medium accounting.go:72). Guard each check-then-append pair with a
package-level accountingMu (Executor is used by value, so a struct field would not
be shared). + TestRecordSpecialistStopDedupesUnderConcurrency (passes under -race).
* audit batch 11 (zeroruntime/gemini): O(1) text accumulation; gemini cached-token counts
- zeroruntime CollectStreamWithOptions accumulated assistant text with
`collected.Text += event.Content`, reallocating the whole string on every chunk
(O(n^2) over a long streamed response). Accumulate in a strings.Builder on the
collector and materialize it once in flush, the single finalization point hit
before every return (audit low helpers.go:104). Existing collect tests still pass.
- gemini decoded usageMetadata without cachedContentTokenCount, so a cached-prompt
response reported zero cached input tokens while the other providers report them
(audit medium gemini/types.go:88). Decode the field and thread it through
streamState into NormalizeUsage as CachedInputTokens. + extended
TestStreamCompletionEmitsTextUsageAndReasoningTokens.
* audit batch 12 (specialist): parse child stream without a line-length cap; drop dead helper
- ParseStream used a bufio.Scanner capped at 1 MiB, so one large stream-json line
from a child (a big tool result or final answer) hit bufio.ErrTooLong and aborted
the entire specialist run (audit medium streamer.go:43). Switch to a bufio.Reader
with ReadString, which has no per-line limit; the child is our own trusted
subprocess, so its output length is the legitimate bound. Line numbering and
blank-line/EOF handling are preserved. + TestParseStreamHandlesLineLargerThan1MiB.
- remove dead formatTaskOutput (output_tool.go:244): zero callers and zero tests;
it only forwarded to formatTaskOutputSummary, which is the one actually used.
* audit batch 13 (background/specialist): kill background tasks as a process group
Background children were launched in the parent's process group and terminated by
signalling only the single PID, so any process the task forked was orphaned and
outlived a cancel; the signal also risked hitting a recycled PID after the child
was reaped (audit medium process_posix.go:38/50).
- ConfigureChildProcessGroup (Setpgid on POSIX, no-op on Windows where taskkill /T
already tree-kills) is applied at launch so the child leads its own group.
- terminateProcess now SIGTERM/SIGKILLs the negative PID (the whole group), with a
pid>1 guard so a bogus 0/1 can never expand to "our own group" or "everything",
and treats ESRCH as already-gone. Liveness polls the group. Targeting a group
(rarely recycled vs. a bare PID) also shrinks the reaped-then-recycled window.
- specialist launchBackgroundProcess opts every child into its own group; on a
SetPID failure it now kills the child + group, marks the task errored, and records
the stop (deduped) instead of leaking an untracked orphan.
- tests launch as group leaders; new TestTerminateProcessKillsForkedChildren proves
a forked grandchild dies with the group.
* audit batch 14 (sandbox): quote-aware shell segment splitting
splitShellSegments used a quote-unaware strings.Replacer, so a shell operator
inside quotes was treated as a separator: `git commit -m "use top | less"` split
into a `less` segment and `echo "a; vim b"` into a `vim` segment, both falsely
flagged as interactive (audit medium safe_command.go:138).
Replace it with a quote-aware scanner that mirrors the shell: single quotes make
everything literal; double quotes keep $(...)/`...` substitution active but treat
|, ;, && as literal; unquoted text splits on the same operator set as before
(;, |, ||, &&) plus substitution boundaries. Real unquoted operators still split,
so an interactive program behind a separator — or inside a live `"$(...)"`
substitution — is still caught (no new false negatives, the security-relevant
direction). + TestDetectInteractiveQuoteAwareSeparators covering both directions.
* audit batch 15 (cron): collapse DST fall-back repeated hour to one fire
On a fall-back day the clock repeats an hour (e.g. 01:30 EDT then 01:30 EST), so
Next("30 1 * * *", <01:30 EDT>) returned the same-day 01:30 EST — firing a daily
job twice (audit medium schedule.go:171, which previously guarded only the
spring-forward gap).
Next now skips a match whose local wall-clock minute equals `after`'s but whose
absolute time is later (the repeated-hour duplicate) and keeps searching. Normal
forward search always advances the wall-clock, so this only triggers on the
fall-back repeat; when the scheduler passes the last fire time as `after`, the
repeated hour collapses to a single fire. + TestNextDSTFallBackDoesNotRepeatHour
(spring-forward termination test still passes).
Note: Next is stateless, so it dedupes relative to `after`; a caller that passes
an arbitrary mid-hour "now" instead of the last fire time is out of scope here.
* audit batch 16 (mcp): skip SSE notifications before the response; larger SSE buffer
- decodeSSERPCMessage returned the first non-empty `message` event unconditionally,
so a server-initiated notification/request arriving before the response made the
caller see an id mismatch and fail (audit medium network_client.go:621). It now
skips any message carrying a method (notifications/requests have one; a response
does not) and returns the first real response; the caller's rpcIDMatches still
validates the id. + TestDecodeSSERPCMessageSkipsNotifications.
- raise the per-event SSE scanner cap from 1 MiB to a bounded 8 MiB so a large but
legitimate MCP message no longer hits bufio.ErrTooLong and fails the request
(audit medium network_client.go:637); still bounded against an unbounded server.
Out of scope (kept): full reconnect of a persistent SSE stream after a fatal read
error — a larger change than this remediation.
* audit batch 17 (sessions): fsync session metadata before the atomic rename
writeMetadata wrote the temp file with os.WriteFile (no sync) and renamed it into
place, so a crash right after the rename could expose a metadata file whose bytes
were never flushed — a torn or empty file that corrupts the whole session (audit
medium store.go:632). Write+fsync the temp via a new writeFileSync helper before
renaming, closing that window. + TestWriteFileSyncRoundTrips.
Deliberately scoped:
- Event-log appends (appendEventLocked) are NOT fsynced per append: that would add
a disk flush to every event (every tool call), and a hard-crash loss of the log's
unsynced tail is acceptable, whereas torn METADATA is not. Metadata is the
integrity-critical part and is what this syncs.
- Directory fsync is omitted for cross-platform simplicity (it errors on Windows);
the file fsync already prevents the torn-contents failure, the serious case.
Left for follow-up (in this bucket but not safe/clear wins here):
- hooks append sequence still re-reads the file per append; the in-memory cache is
cross-process-unsafe and the safe last-line read is fiddly for a low-volume log.
- Fork event re-append/de-dup is nuanced usage-accounting and needs its own change.
* audit batch 18 (agent): count tool-defs in compaction estimate; don't deny an always-allow on persist failure
- maybeCompact's estimate omitted the tool definitions, which ride on every
request, so the real input could exceed the model limit while the message-only
estimate stayed under threshold and compaction never fired (audit medium
compaction.go:58). partitionTools is now computed before maybeCompact (it does
not depend on the messages) and the exposed tools' estimated tokens are added to
both the threshold check and the post-compaction shrink check. + estimateToolDefTokens
and TestEstimateToolDefTokensCountsDefinitions.
- PermissionDecisionAlwaysAllow denied the call when persistPermissionGrant failed,
overriding what the user explicitly allowed (audit medium loop.go:468). Persisting
is now best-effort: a failure (or no sandbox engine) just means the grant is not
remembered and the user is re-prompted next time, not denied now. This also drops
the dead requestEvent.GrantMatched/Grant writes (audit low loop.go:473) — the
emitted event derives them from the sandbox decision via buildPermissionEvent.
Left intentional (documented, not defects): the reactive-retry path omits OnText to
avoid duplicating mid-stream text (loop.go:183); OnContext/MeasureContext is a
complete, tested context-breakdown scaffold awaiting a consumer (types.go:183).
* audit batch 19 (usage): price escalated usage from the event's own model
exec persists payload["model"] on --allow-escalation runs (the model can change
mid-run), but BuildReport priced every event from the session's Metadata.ModelID
and never read the payload, so usage from an escalated model was mis-priced at the
base model (audit medium report.go:17). usageEventPayload now carries Model and
BuildReport prefers it, falling back to the session model when absent (older
events stay byte-identical and behave as before). + TestBuildReportPricesFromEventModelWhenPresent.
* audit batch 20 (sessions): don't copy usage events into a fork (no double-count)
Fork re-appended every parent event, including provider_usage, into the child, so
a usage report aggregating the parent and the fork double-counted the parent's
usage (audit medium store.go:387). Skip EventUsage when copying — it already
counted against the parent and is not part of the conversation history a fork
replays — and record the actual copied count in the fork marker. + TestStoreForkSkipsUsageEvents.
* audit batch 21 (cli/skills): warn on duplicate skill names instead of silently dropping
skills.Load deduplicates same-named skills (first directory wins) and records the
dropped collisions via skills.Duplicates, but nothing surfaced them, so a shadowed
skill just vanished with no signal — and Duplicates had no production caller (audit
low skills.go:91). `skills list` now reports each collision to stderr (keeping
stdout/--json clean), using Duplicates. + TestRunSkillsListWarnsOnDuplicateNames.
Note: skills.Get is kept — it is a by-name accessor used throughout the package's
tests, not dead code.
* audit batch 22 (cli/cron): capture the run error from stream-json stdout
Cron jobs run exec with --output-format stream-json, so a failure is reported as an
`error` event on STDOUT, but the run record's Error was set only from stderr — so a
failed job often recorded an empty/uninformative error while the real message sat
unread in outBuf (audit low cron_run.go:150). On a non-zero exit, scan the stdout
stream-json for the error event's message and prefer it, falling back to stderr.
+ extractStreamJSONError and TestExtractStreamJSONError.
* audit batch 23 (sandbox): richer macOS seatbelt profile (signal + mach-lookup)
The generated sandbox-exec profile was default-deny with only process/sysctl/file
allowances, so two real gaps remained on macOS (sandbox quality report H1):
- A sandboxed script could not signal the children it spawned — `kill` returned
"Operation not permitted" under seatbelt, breaking common `cmd & ... kill`,
test-runner, and timeout patterns. Add `(allow signal (target self) (target pgrp))`,
which stays scoped to the command's own process group.
- XPC to system daemons was denied, so keychain (securityd/trustd), user/group
lookup (opendirectoryd), preferences (cfprefsd), network config
(SystemConfiguration), launch services, and the pasteboard all failed. Add a
curated `(allow mach-lookup ...)` allowlist (`sandboxMachServices`).
Neither touches the file-write or network rules, so the workspace boundary is
unchanged — verified on a real macOS host: `security`/`scutil`/`pbpaste`/self-kill
now succeed while writes to $HOME and /etc are still denied. iokit-open was tried
and dropped as unnecessary. + unit assertions (TestSandboxExecProfileGrantsSignalAndMachLookup)
and extended the darwin integration test with a self-kill case and an
outside-workspace deny check.
* audit batch 24 (sandbox/tools): remove dead OnSandboxDecision hook
RunOptions.OnSandboxDecision had no setter anywhere, yet registry.RunWithOptions
spawned a goroutine (with panic recovery) for it on every sandboxed tool call —
pure per-call overhead for an unreachable callback (sandbox report M1). The sandbox
decision is already surfaced to observers via the permission event
(buildPermissionEvent reads the decision), so this hook is redundant; delete the
field and its call site.
* audit batch 25 (sandbox/cli): exact-path grants — create and revoke by path
The engine already matched ScopeFile grants and DeriveScope already produced them
from path/file tool args, but the CLI could neither create one explicitly nor
revoke a single one (sandbox report L3 / prompt 7). Add:
- GrantStore.RevokePath(tool, path): revokes only the grant whose scope matches the
given file/dir, leaving tool-wide and other-path grants intact (path canonicalized
to absolute like stored scopes). + TestGrantStoreRevokePathRemovesOnlyMatchingScope.
- `zero sandbox grants allow <tool> --path <p>`: persists an exact-file (ScopeFile)
grant, path resolved to absolute so it matches lookups and revokes.
- `zero sandbox grants revoke <tool> --path <p>`: revokes just that grant (default
still revokes all grants for the tool). + TestRunSandboxGrantsCreateAndRevokeByPath.
The TUI permission-card "Allow always (exact path)" option is intentionally left for
the TUI feature branches (it overlaps #187/#188); the engine + CLI now cover the
full create/match/revoke round-trip for file-scoped grants.
* audit batch 26 (sandbox): Engine.Precheck — report violations before execution
Add Engine.Precheck(ctx, request) []Violation, which reports the sandbox
violations that would block a tool request before it runs (sandbox report / prompt 6).
It reuses Evaluate so policy is not duplicated: an allowed or merely-prompted
request yields no violations; a denied request yields its violation (via the shared
violationsFromDecision helper, with a ViolationPolicyDenied fallback for a deny that
carries no structured violation). A nil engine yields nothing.
+ TestEnginePrecheckReportsViolationsBeforeExecution.
Wiring Precheck into the batch-confirmation prompt is intentionally left to the TUI
branch: it touches prompt rendering, and short-circuiting the agent loop's deny path
would skip the before/after-tool hooks that currently fire around a policy-denied
call. The engine API is in place for that consumer.
* audit batch 27 (sandbox): scoped-egress domain prompt with timeout + caching
The scoped-egress proxy failed closed on any host outside the allowlist. Add an
opt-in DomainPrompt callback (prompt 8): an UNKNOWN host (neither allowed nor
explicitly denied) is authorized at request time via the callback instead of being
refused outright. An explicitly denied host is still refused without prompting; the
callback is bounded by PromptTimeout (default 60s, timeout/error => deny); decisions
are cached for the proxy's lifetime so a host is prompted at most once. With no
callback set the strict fail-closed behavior is unchanged. Wired through both the
CONNECT and HTTP handlers via authorizeTarget.
+ TestEgressProxyAuthorizeDomainPrompt / ...TimeoutDenies / ...NilPromptFailsClosed.
The user-facing prompt that supplies the callback is left to the permission UI (TUI)
branch; the egress mechanism (callback + timeout + cache) is in place and tested.
* audit batch 28 (sandbox): AST-based shell analysis (AnalyzeCommand)
Add AnalyzeCommand(script) AnalysisResult, a static shell analyzer built on the
mvdan.cc/sh/v3 parser (prompt 12). Walking the parsed command tree makes it a more
precise second opinion than the regex detector: a program name only counts when it
is an actual command, so `echo "vim ..."`, `printf 'open with vim'`, and
`git commit -m "rm -rf /"` are clean, while real commands are flagged —
interactive (editors/pagers + REPLs, with the same -e/script suppression as
nonInteractiveREPLFlags), destructive (rm -rf/-fr, dd, mkfs, shred, ...), and
network (curl/wget/ssh/nc/...). An unparseable script yields TooComplex so callers
can treat it as higher-risk. + TestAnalyzeCommand (16 cases) / ...EmptyIsClean.
Dependency: mvdan.cc/sh/v3 pinned to v3.11.0 — compatible with the existing go 1.24
directive (the latest v3.13.1 would have bumped the module to go 1.25). It is kept
as a standalone analyzer for callers to consult; feeding it into Engine.Evaluate is
deliberately not done here, since that would change allow/deny classification.
* audit batch 29 (sandbox): unify proxy-env generation (ProxyEnv)
Export ProxyEnv as the single source of truth for proxy-env injection (prompt 9
req 1), replacing the unexported scopedProxyEnv used by the sandboxed-shell path.
+ TestProxyEnv.
Investigation that bounds the rest of prompt 9 (documented in the ProxyEnv doc):
- web_fetch already honors HTTP_PROXY/HTTPS_PROXY — its transport clones
http.DefaultTransport, whose Proxy is http.ProxyFromEnvironment.
- MCP children already inherit the parent env (mergeProcessEnv appends os.Environ),
so they pick up any proxy vars the agent has.
So the only missing link to scope FetchUrl/MCP is a SESSION-level egress proxy whose
address reaches the agent process. That is deliberately NOT wired here: doing it
safely requires allowlisting the active LLM provider's own domain first, or the
agent's provider calls would route through the scoped proxy and be denied — a
correctness pitfall that also can't be verified end-to-end on this host. Flagged
rather than shipped blind.
* audit batch 30 (sandbox): Linux seccomp Unix-socket block — UNVERIFIED, needs Linux CI
Adds a pure-Go (no cgo, no vendored binary) seccomp BPF filter that denies
socket(AF_UNIX) with EPERM on x86-64/arm64, closing the Unix-socket gap bubblewrap's
filesystem/network isolation leaves open (prompt 11):
- internal/sandbox/seccomp.go: the classic-BPF program as a platform-neutral
[]sockFilter, built and UNIT-TESTED (structure + every jump offset in range — the
classic way a hand-written BPF filter goes silently wrong).
- seccomp_linux.go: ApplyUnixSocketBlock installs it via prctl(NO_NEW_PRIVS) +
prctl(SET_SECCOMP, MODE_FILTER). seccomp_other.go is a no-op everywhere else.
- cmd/zero-seccomp: a tiny linux-only exec wrapper that applies the filter then
execs the real command (the standard way to install seccomp in a child with
os/exec); degrades gracefully (warns + runs) if the kernel lacks seccomp.
⚠️ HONEST CAVEAT: I developed this on macOS and CANNOT run the actual AF_UNIX block
here. darwin build, `GOOS=linux` cross-compile, vet, and the structure test all pass,
but the unit test verifies the program's SHAPE, not that the kernel actually blocks
AF_UNIX — that MUST be verified on Linux CI (create a Unix socket under the wrapper
and assert EPERM). Safe to ship as-is: it is linux-only, no-op on every other
platform, and not wired into the bwrap command yet (opt-in prefixing the sandboxed
command with zero-seccomp is the remaining integration), so it cannot regress any
current path.
* audit batch 31 (sandbox): macOS denial log monitor (opt-in, default off)
Re-adds the macOS seatbelt-denial monitor as an opt-in feature (prompt 10). When
Policy.MonitorDenials is set, the sandbox-exec profile tags its default-deny with a
marker and bash tails `log stream` for that tag during the command, appending any
captured denials as a <sandbox_violations> block to the command's stderr so the
model can see what was blocked.
- DenialMonitor (darwin) tails/parses tagged denials with a capped, deduped ring
buffer and noise filtering; no-op stub on other platforms. parseSandboxDenyLine is
unit-tested. + profile-tag test + appendSandboxViolations test.
- Default OFF: with MonitorTag empty, StartDenialMonitor is a no-op and the command
path is byte-for-byte unchanged, so there is no regression or per-command overhead
unless enabled.
CAVEAT: on at least one macOS host (verified live) seatbelt denials are NOT delivered
to the `log stream`-queryable unified log, so the monitor captures nothing there. It
is the standard mechanism and works on macOS versions that do log denials; shipping
it default-off means it never affects whether a command runs.
* audit batch 32 (sandbox): wire seccomp Unix-socket block into bubblewrap (opt-in)
Completes prompt 11: the zero-seccomp helper (which installs the AF_UNIX seccomp
filter) is now actually invoked by the sandbox instead of only existing as a
standalone binary.
- bubblewrapCommandPlan, when Policy.BlockUnixSockets is set, ro-binds the
discovered zero-seccomp helper into the sandbox at its host path and prefixes the
command with it so the filter is installed before the real argv runs.
- findSeccompHelper discovers the helper next to the running executable first, then
on PATH; it returns "" when absent, so the sandbox degrades gracefully (runs
without the extra filter — bubblewrap's fs/net isolation still applies) rather
than failing the command. Exposed as a package var so the wiring is unit-tested
on any OS.
- Reachable from config: SandboxConfig.BlockUnixSockets and .MonitorDenials now map
onto the policy in applyConfiguredSandboxPolicy (opt-in only — config can turn a
hardening flag on, never off). Both default OFF.
- Tests: helper-prefix present when enabled / absent by default; config flags apply
independently and stay off when omitted.
Default OFF and Linux-only effect; the runtime seccomp enforcement still needs a
Linux host/CI to exercise end-to-end (the wiring and BPF program are unit-tested).
* audit batch 33 (sandbox): enforce scoped/deny network policy in web_fetch & web_search
Completes prompt 9: the built-in network tools now honor the SAME allow/deny/scoped
policy the sandboxed shell egress proxy enforces, instead of bypassing it. Before
this, web_fetch/web_search would reach any public host even when the policy was
NetworkDeny or NetworkScoped — the egress proxy only constrained shell commands.
- New shared gate Engine.NetworkHostAllowed(host) reuses the egress domain matcher
(domainAllowed/normalizeDomains/effectiveNetwork) as the single source of truth:
allow → all hosts; deny → none; scoped → only AllowedDomains minus DeniedDomains
(empty allowlist collapses to deny). Disabled policy / nil engine impose nothing.
- web_fetch is now sandbox-aware: the host is checked before the request AND on every
redirect, so a denied/unlisted host fails closed before any dial. Plumbed via a
networkPolicyGate so the no-sandbox path is byte-for-byte unchanged.
- web_search is sandbox-aware: the configured backend's endpoint host is checked
before the query leaves the machine; blocked under deny, and under scoped unless the
backend host is allowlisted.
- The registry already routes sandbox-aware tools through RunWithSandbox when an
engine is present, so this activates automatically wherever the sandbox is wired.
- Tests: engine gate matrix (deny/allow/scoped/denylist/empty/disabled/nil + host:port);
web_fetch & web_search block denied/unlisted hosts without dialing and allow listed
ones; endpoint-host parsing.
* audit batch 34 (sandbox): prove network-policy wiring end-to-end + document opt-in flags
Verification follow-up to batches 31-33; no behaviour change.
- Adds a registry-level test that exercises the FULL chain for the scoped-network
enforcement: registry.RunWithOptions -> engine.Evaluate (passes a scoped,
egress-capable sandbox-exec backend) -> routes web_fetch through RunWithSandbox ->
per-host allowlist blocks an unlisted host before any dial. This proves the
Tool-interface value actually satisfies sandboxAwareTool at the registry boundary,
not just in a direct method call.
- Documents the two opt-in hardening flags (sandbox.blockUnixSockets,
sandbox.monitorDenials) and the scoped web_fetch/web_search behaviour in the README
so the config keys are discoverable. Both remain off by default.
Confirmed wiring: agent loop forwards options.Sandbox to the registry; the registry
routes sandbox-aware tools (web_fetch, web_search) through RunWithSandbox when an
engine is present; MonitorTag is set only on the macOS sandbox-exec plan; the
seccomp helper prefix is added only on the bubblewrap plan when BlockUnixSockets is
set; both config flags map onto the policy via applyConfiguredSandboxPolicy.
* audit batch 35 (sessions): fix Windows CI failure in TestWriteFileSyncRoundTrips
The exact-permission assertion (perm == 0o600) added in batch 17 fails on
windows-latest because Windows does not honor Unix permission bits: Go reports
0o666 for a writable file regardless of the mode passed to OpenFile. This was the
sole cause of the failing Smoke (windows-latest) CI job; macOS and Ubuntu passed.
Guard the perm check with runtime.GOOS != "windows" so it still verifies the mode
on the platforms that enforce it, while the round-trip (write + read-back) is still
asserted on every platform.
* audit batch 36: address CodeRabbit review (5 findings)
- background/process_posix: after SIGKILL, poll until the process group is
actually gone (SIGKILL is async) and return an error if it survives past a
second deadline, instead of returning nil while descendants still race.
- sandbox/safe_command: only treat ')' as a substitution boundary when it closes
an active $(...). A literal ')' (e.g. echo "a) less") no longer splits into a
fake `less` segment and is no longer misflagged as interactive. Depth-tracked so
nested $(...) still isolate their inner command. Direct splitShellSegments test
(fails pre-fix: yields ["echo \"a", "less\""]).
- cron/schedule: the DST fall-back collapse now only applies when `after` sits
exactly on the minute boundary (its "last fire time" form). With sub-minute
precision (e.g. 01:30:30 EDT) the first 01:30 fire already passed, so the repeated
01:30 EST is the legitimate next fire and is returned — restoring strictly-after
semantics. New test fails pre-fix (skipped to next day).
- config/types: maxTurns error message now reads "must be >= 0" to match the check
(0 is accepted; only < 0 is rejected). Negative-maxTurns test asserts the message.
- docs/audit: header date/branch metadata now matches the body (2026-06-13,
fix/audit-batch) instead of the stale 2026-06-11/fix/audit-critical-high snapshot.
Verified: gofmt clean; go vet clean; host + linux + windows builds; affected suites
green. Each behavioural fix ships with a test confirmed to fail without the change.
* audit batch 37: address CodeRabbit re-review (12 findings)
Findings on the audit code from batches 21-36; each behavioural fix ships with a
regression test (several confirmed to fail without the change).
sandbox/analyzer (AnalyzeCommand):
- Unwrap launcher prefixes (sudo/env/nice/bash -c/...) and recurse into `sh -c`
payloads so `sudo rm -rf`, `env curl …`, `bash -c 'vim x'` classify on the real
command, not the launcher. Mirrors DetectInteractiveCommand.
- Honor rm's `--` end-of-options marker so `rm -- -rf` (delete a file named -rf) is
not flagged destructive.
sandbox/engine: NetworkHostAllowed now shares one backend-aware effective-mode
helper with Evaluate, so scoped collapses to deny when the backend can't enforce
scoped egress — the per-tool gate can no longer permit traffic the engine-level
decision would fail closed.
sandbox/egress: cache domain-prompt decisions by host:port, not host, so one
"allow" can't authorize other ports on the same host.
sandbox/safe_command: the segment splitter is now escape-aware (\| , \" ) so an
escaped operator/quote can't manufacture a fake interactive segment.
sandbox/log_monitor (darwin): Wait() the `log stream` child after draining stdout
so the cancelled process isn't leaked as a zombie.
tools/web_search: confine the search backend to same-host redirects (with a limit)
so a redirect chain can't egress to a host the scoped/deny policy never authorized.
cli/sandbox: an explicit empty --path (`--path=` / `--path ""`) now fails closed
instead of silently widening an allow to tool-wide or a revoke to all-grants.
cli/skills: warn on stderr when duplicate-skill detection fails instead of
swallowing the error.
specialist/exec: don't mask a failed orphan-kill — join the TerminateProcess error
with the SetPID error so a surviving process is visible.
background/process_posix: resolve the PGID and only group-signal when pid leads its
own group; otherwise signal the individual PID. Avoids both a false-success on a
non-leader ESRCH and the hazard of signalling an unrelated (possibly our own) group.
Verified: gofmt + go vet clean; host + linux + windows builds; full go test ./...
green.
* audit batch 38: address CodeRabbit re-review round 2 (3 findings)
Follow-ups to batch 37, each with a regression test:
- safe_command (splitter): a ')' is now only a substitution boundary when it
closes an active, UNQUOTED $(...). A quote-state stack saved at each '$(' lets a
substitution run in a fresh quoting context and restores the outer quoting on
its matching ')'. Fixes `echo $(printf "a) less")` splitting into a fake `less`
segment, while still isolating the inner command of `echo "$(vim x)"`.
- egress: deduplicate in-flight domain prompts per host:port. Concurrent requests
for the same unknown target now wait on the first prompt and reuse its cached
decision instead of each firing a prompt (a prompt storm) and racing to write
the final decision. Race-tested with 25 concurrent authorizers → one prompt.
- analyzer + safe_command: wrapper option-value consumption is now wrapper-specific
(wrapperValueOptionsByProg) instead of a global option set. A valueless flag like
`sudo -n` no longer swallows the real payload, so `sudo -n rm -rf` /
`sudo -n curl …` are correctly classified destructive/network; `sudo -u root vim`
still consumes its value. Shared by the AST analyzer and the regex detector so
they can't diverge.
Verified: gofmt + go vet clean; host + linux + windows builds; go test ./... and
-race on sandbox/background all green.
* audit batch 39: address CodeRabbit re-review round 3 (12 findings)
All verified against current code; each behavioural fix has a regression test.
Security / correctness:
- tools/web_search: redirect policy now also refuses a scheme change, blocking a
same-host https→http downgrade that would send the query + bearer token over
plaintext.
- sandbox/safe_command: a ')' is only a substitution boundary when it closes an
active UNQUOTED $(...), and backticks now get the same quote-state save/restore
as $( — so `echo "`a | less`"` and `echo "$(true | less)"` no longer hide the
inner pager from interactive detection.
- sandbox/analyzer + safe_command: wrapper option-value consumption stays
wrapper-specific, and unwrapping no longer aborts on a dynamic ($x) wrapper arg
once a wrapper is active, so `env "$opts" curl` / `sudo "$x" rm -rf` are still
classified.
- sandbox/egress: in-flight prompts deduped per host:port (carried from batch 38);
the prompt callback is now cancellable (context cancelled on timeout) so a stuck
prompt can abort instead of leaking; signature threaded through.
- sandbox/runner: per-plan unique denial tag (pid+counter) so concurrent monitored
sandbox-exec runs can't ingest each other's denials; helper selection now
requires an executable regular file so a non-exec sibling degrades gracefully.
- mcp/network_client: aggregate SSE event-size cap (not just per-line) so a server
can't grow memory with many unterminated data: lines.
- specialist/accounting: a previously-recorded stop/usage with an empty runId is a
catch-all and now suppresses a later runId-bearing duplicate.
- sessions/lineage: Tree fetches the root via Get() first so a corrupt root
surfaces its real error instead of degrading to "not found".
Docs/tests:
- background/terminate: docstring now states the leader-only group-kill (PID-only
fallback for non-leaders); test child-liveness probe uses ESRCH specifically.
- cli/sandbox: grant usage strings include --path.
Verified: gofmt + go vet clean; host + linux + windows builds; go test ./... and
-race on sandbox/background all green.
* audit batch 40: address CodeRabbit re-review round 4 (8 fixed, 1 skipped)
Verified each against current code.
Fixed:
- sessions/lineage: PANIC FIX — store.Get returns (nil, nil) for a missing
session, so the batch-39 root prefetch could nil-deref. Guard root == nil and
return a not-found error. Regression test added (was a panic).
- agent/compaction: the reactive recover() now records lowWaterMark in the SAME
combined (messages + tool-defs) token domain maybeCompact uses, so the proactive
shrink-guard compares like with like. recover() takes tools; callers pass
request.Tools.
- mcp/network_client: SSE aggregate counter no longer counts a joining newline for
the first data line (only when prior content exists), avoiding premature rejects.
- sessions/store: fsync the parent directory after the metadata rename so the
rename is durable across a crash (no-op on Windows, which can't fsync a dir).
- sandbox/egress: parse the target port with strconv.Atoi instead of
net.LookupPort (no context-unaware resolver use).
- sandbox/runner: escape the per-plan denial tag through sandboxProfileString when
embedding it in the seatbelt profile.
- sandbox/seccomp_linux: guard against an empty filter program before taking
&kernelFilters[0] (defensive; the program is fixed non-empty today).
- cli/cron_run_test: assert last-error-wins with two error events.
- background/terminate, cli/sandbox usage, process_posix_test ESRCH (carried).
Skipped (with reason):
- zerogit worktree-rename (Y='R') test: git porcelain v1 -z only emits the
rename-source field when the INDEX column is R/C; the worktree column never
carries 'R' with a source field in v1, so the fixture would test output git
doesn't produce, and making parseStatus consume on code[1]=='R' would risk
mis-consuming the following entry for a plain ` R` status. Left as-is.
Verified: gofmt + go vet clean; host + linux + windows builds; go test ./... and
-race on sandbox/background all green.
* audit batch 41: address CodeRabbit re-review round 5 (4 findings)
All verified against current code; code fixes have regression tests.
- agent/compaction: summarizeWithFallback's reduce pass no longer swallows ALL
errors. A context-limit error still falls back to the joined partial summaries
(documented "extreme" case), but a non-context failure (auth/network/provider)
now surfaces unchanged, per the function's contract. Two tests (propagate vs.
joined-fallback); the propagate test fails without the fix.
- sandbox/safe_command + analyzer: wrapper value-consuming options now include the
long spellings (sudo --user root, env --unset NAME, timeout --signal …), so a
long flag's value is no longer mis-read as the program (interactive/destructive/
network detection bypass). A `--flag=value` token carries its own value and never
consumes the next token. Tests for space and = forms in both the AST analyzer and
the regex detector.
- docs/audit: the status-ledger summary table's open/partial cells (64/14) were the
lone outlier — the ledger's own narrative and 2026-06-13-reverification.md both
state 66/12. Corrected to 66/12 (66+12+97 = 175); derivation: body 69 open + 18
partial minus the 9 already-fixed-on-main (3 open + 6 partial) = 66/12 = 78
pending, fixed 88+9 = 97. Added a comment documenting the summary-vs-body
relationship. The reverification doc already states 66/12, so both now agree.
Verified: gofmt + go vet clean; host + linux + windows builds; full go test ./...
green.
* audit batch 42: address CodeRabbit re-review round 6 (1 fixed, 1 kept w/ proof)
CodeRabbit re-surfaced two "duplicate" refinements; CI was already green (its 6th
pass was a COMMENT with no new findings).
- cli/sandbox_test (TestRunSandboxGrantsRejectsEmptyPath): now seeds a tool-wide
grant and asserts grant-store immutability after EACH rejected empty-`--path`
call (reflect.DeepEqual before/after), so a mutation in one call can't be masked
by a later one — and a buggy "revoke all" is actually observable (it's a no-op on
an empty store). Stronger than the suggested patch.
- zerogit.parseStatus: KEPT consuming the rename source on the index column only
(code[0]), with an explanatory comment. Verified empirically that git porcelain
v1 -z reports a rename/copy (and emits the extra source field) only in the index
column: `git mv` → "R new\0old\0"; a worktree-only rename → " D old\0?? new\0"
(delete + untracked, never "R" in code[1]). Consuming on code[1]=='R'/'C' would
match no real git output and would only risk mis-consuming the next entry on
malformed input, so the suggestion is declined as incorrect for v1.
Verified: gofmt + go vet clean; host + linux + windows builds; affected suites green.

tui/resume: list only standalone conversations, not sub-runs (#169)
The /resume picker called sessions.Store.List() unfiltered, so it showed every session directory — including the child (specialist/sub-agent) and spec draft/impl sessions an agent spawns by the dozen per conversation. That flooded the picker (the reported '… 779 more · /resume <id>') even though the TUI creates exactly one session per conversation. Add Store.ListResumable()/LatestResumable() (and an IsResumableKind predicate) that keep only regular and user-fork sessions, and use them for the picker and for '/resume latest' so latest never lands on a newer child/spec sub-run. An explicit '/resume <id>' still resolves any session by id. Covered by TestListAndLatestResumableExcludeSubRuns and TestResumePickerExcludesSubRunSessions. |

audit: address PR review findings (security, correctness, tests)
Fixes from the code review on the critical/high audit branch: - tools/apply_patch: parseHunkCounts now reads only the range section between the opening and closing "@@". A crafted section heading like "@@ -1,1 +1,1 @@ +1,999999" could otherwise overwrite the line count, wedge the parser in hunk mode, and swallow later file headers so they escaped validatePatchPaths / recheckPatchWriteTargets — a workspace-confinement bypass. - providerhealth: the SSRF-hardened dial now tries every validated address in order instead of pinning addrs[0], so a dual-stack/multi-record provider isn't failed by a single dead record. Extracted dialValidatedAddrs for coverage. - hooks/dispatch: a beforeTool hook killed by its deadline now fails CLOSED (vetoes the tool) instead of fail-open. A launch failure (missing binary) still fails open so a misconfigured hook can't wedge every tool call. - cron: Store.Get returns a distinct ErrJobNotFound sentinel; cron_run only treats that as "removed during run" and still records/persists on a transient read error instead of silently dropping the run. - providers/anthropic: closeOpen finalizes thinking buffers still open at stream end (SSE ended after thinking_delta/signature_delta but before content_block_stop), so they survive in the done event's ReasoningBlocks for replay. Finalized in index order. - providers/gemini: corrected the stale thinkingConfig comment (no IncludeThoughts field; thought summaries are suppressed by skipping part.Thought parts). Tests: regression coverage for each fix, plus the requested nitpicks — EOF-terminated MCP line, recipe-prompt propagation assertion, checked file.Close() in session store tests, and a shortened bash process-group timeout test via the bashWaitDelay hook. Note: declined the suggestion to replay a "signature" on redacted_thinking blocks — Anthropic's redacted_thinking carries only an opaque "data" field; the signature is for regular thinking blocks, and the stream never populates one for redacted blocks. |

sessions: only tolerate a torn tail when the final line is unterminated
The torn-tail tolerance dropped any malformed final line, including a complete-but-corrupt line ending in a newline — silently swallowing real corruption. A genuine torn tail is an incomplete write with no trailing newline; gate the tolerance on that so a fully-flushed corrupt line fails loudly again, while a truncated final line is still recovered. |

sessions: tolerate a torn tail when reading the event log
ReadEvents returned an error on any malformed JSONL line, so a single interrupted append (truncated final line) made resume hard-fail and lose the whole session. Drop only a malformed final line (a torn tail); malformed lines earlier in the file are real corruption and still error. |

TUI scrollback re-architecture, Lime chat surface, and deep-audit fixes (#158)
* docs(design): add Lime TUI prototype and rebuild spec
* tui: remove the zeroline skin system
One design remains in the tree ahead of the Lime rebuild: the zeroline
package, its TUI view/skin plumbing (Options.Skin/ThemeVariant/ThemeDark,
model skin branches, theme picker), and the zeroline CLI subcommand are
gone. /theme keeps its shell-only message.
* tui: replace the cyan palette with the Lime token table
theme.go is rebuilt around the Lime design tokens (docs/design/
zero_tui_lime.html): near-black panels, one lime accent, solid tint
stand-ins for the prototype's rgba overlays. Existing render sites map
onto the new role styles (ink/line/userPrompt/toolName/toolArg) without
layout changes; no hex exists outside theme.go.
* tui: build the Lime chat-surface components
Title bar with brand badge + context window, empty state replacing the
deleted splash (block-art 0, tagline, 1-3 starter suggestions), stream
blocks (user prompt gutter, muted interim with cursor, final-answer
accent rail, done line, bordered notes), tool cards with diff/read/
bash/grep bodies and MiniDot run spinner, borderless composer with
run-state hints, and the grouped status line. Final answers are marked
at append time; resolved tool calls collapse into their result cards.
* tui: fix Stage 2 review findings
Adversarial review of the chat-surface commit confirmed 15 issues, all
fixed here:
- wrapPlainText sliced wide runes by rune count: CJK/emoji prose could
panic the TUI or emit lines ~2x the measure; split at width instead
- a cancelled run's streamingText leaked into the next turn's interim
block; cancelRun now clears it
- orphaned tool-call cards (cancelled/errored turns) re-animated with
the spinner on any later run; the glyph is now scoped to the call's
own runID
- starter-suggestion digit capture was active while the chips were off
screen (/clear mid-run); the guard now mirrors the render condition
- prompt submits while a deferred Ctrl+C quit is draining could start a
run the quit would orphan; submission is blocked while exiting
- the running placeholder advertised ctrl+c (which quits) as the
interrupt key; it now says esc
- read-card parser expected 'N: text' but read_file emits 'N | text',
so the gutter and L-range never rendered on real output
- toolCard borders were one column short of the body rows
- diff tint bands now span the full row; NEW FILE renders green on
addBg; preamble/no-newline lines are unnumbered meta and no longer
shift hunk numbering
- card bodies and system notes paint the panel surface; the head gains
the separate faintest arg column (grep target + pattern)
- title-bar overflow now truncates the minimal candidate instead of
rendering the deleted design's 'ZERO … READY' line
- untracked the stray snake-game.html (left on disk, ignored)
* tui: restyle the interactive surfaces for Lime
Permission prompts render as the amber permission card (PERMISSION
badge, risk readout, key chips); resolved prompts collapse to one line
(allowed once/always/denied · tool) and unprompted allows fold into the
tool card's [auto] tag. Ask-user and spec-review prompts share the card
language with line borders. Autocomplete and picker overlays move onto
the panel/selection tints with the accent ❯ marker; model-picker rows
gain the provider dot and ctx · KEY_ENV metadata from the registry and
provider catalog. /resume renders its list as stacked session cards
(id + age, title, meta). Key handling is untouched everywhere.
* tui: adaptive width tiers, doc updates, final polish
Width tiers re-evaluate from the live width: ≥100 renders the full
spec; 80–99 drops the tool-arg column, header ctx, and the status
'interactive' group; 58–79 drops the diff/read gutters, bares the
badge, and keeps provider+tokens+mode; <58 renders a single-segment
header, rail-less cards, and a mode-only status line. Table-driven
tests cover {58,70,80,100,120} plus a frame-wide invariant that no
emitted line exceeds the terminal at any tier. Card bodies expand tabs
so width math holds. Dead splash-chip machinery (startupCommandNames,
startupOrder) is gone; README's TUI section now describes Lime.
* tui: fix final-review findings across Stages 3-4
A second adversarial review confirmed 14 issues, all addressed:
- permission collapse and tool-card pairing are now run-scoped (rcKey):
providers with repeating synthetic ToolCallIDs (Gemini gemini_tool_N)
could attribute a decision or result to a different run's call
- rehydrated always-grants no longer mislabel as 'allowed once'
(GrantMatched fallback)
- the width invariant now actually holds everywhere: empty-state
tagline/hint, ask-user rows, permission detail blobs, pending image
chips, and the sessions trailing hint are wrapped or fitted; the
invariant test renders the empty state and all of those rows at
widths 24-120
- every card (permission, ask-user, spec-review, sessions, notes)
drops side borders on tiny terminals, not just tool cards
- /resume card fields are sanitized against separator bytes from
user-controlled titles
- the picker's selected row paints its gap so the selBg band is solid
- dead splash helpers (normalizedStartupWidth, countLines, nonEmpty,
unreachable rowWelcome branch) and stale /theme comments are gone
- README no longer claims transcript scrolling keys or Tab-accept
behavior that never existed; chatWidth documents its 24-col floor
Tag tui-lime-s4 moves to this commit.
* audit: deep-audit report, TUI scrollback re-architecture, and cross-module fixes
TUI: settled-row flush frontier prints history to native terminal
scrollback (tea.Println, ordered + ack-serialized); View() renders only
the live tail. Full diffs (400-line flush cap) and OSC 8 file:// links
land in history; streamed interim text, cancellation markers, ask_user
exchanges, and composer input history are preserved; run-scoped dedup
keys fix Gemini's repeating tool-call ids; /exit, Ctrl+C-after-Esc, and
cross-session late flushes no longer orphan or contaminate checkpoints.
Cross-module: zero search panic + offset mapping, usage report
robustness, 529 retry, SSE keep-alive watchdog, registry corrections,
update --check on dev builds, MCP ping + mcp list --json secret
redaction, sandbox.network config knob, doctor apiKey presence, atomic
config writes, C1-safe notifications, rune-safe truncation everywhere,
gofmt + vet CI gates, dead glamour dependency dropped.

TUI shell: ask_user modal, pickers, autocomplete, zeroline skin (#127)
* TUI shell: ask_user modal, pickers, autocomplete, zeroline skin Lands the interactive TUI shell on main. (The earlier PR for this content targeted the stacked agent-runtime branch and never reached main, which already has the agent runtime via #125; this re-targets the same reviewed content onto main.) - ask_user: interactive questionnaire modal wired to agent.OnAskUser via an answer channel; transcript rows + session payloads; degrades gracefully without an interactive surface. - compaction sizing: modelContextWindow() sets the agent ContextWindow from the active model's registry entry (unknown models -> 0, compaction off). - pickers (model/theme/effort/mode) + slash-command autocomplete overlay; zeroline skin rendering (boot/home/chat) behind Options.Skin. - checkpoint recording: before each mutating tool the run batches an EventSessionCheckpoint in order and flushes it at end-of-run and on cancel; /rewind reloads in-memory session state so dropped events don't re-reach the agent. Exposes sessions.SnapshotForCheckpoint with an orphan-blob safe-usage contract for the batch-in-order path. build/vet/-race/full-suite + GOOS=windows build green; 116 tui tests; no new deps. * Address #127 review (CodeRabbit): validate checkpoint session id, fix mode toggle, harden ask_user/rewind/flush - sessions.SnapshotForCheckpoint validates the session id (ValidSessionID), matching CaptureToolCheckpoint, so an exported caller can't route blob writes through an invalid session path. - nextPermissionMode: Unsafe now folds to Ask (the stricter landing), not Auto — toggling an Unsafe session must never make it less strict. Test added. - ask_user: a request with zero questions resolves immediately instead of opening a prompt that stalls the run. - cancelled-run flush: surface appendSessionEvents persist-failure rows instead of discarding them (a silently-failed checkpoint flush would degrade /rewind). - /rewind: handle post-rewind reload failures explicitly — on ReadEvents error, clear in-memory context and report, so stale rewound-away events can't reach the next prompt. - transcript dedupe: key ask_user rows on row.id (survives rehydration when row.askUser is nil). - ask_user Esc test: replaced the empty branch with a real assertion (run stays pending after Esc cancels only the prompt). build/vet/-race/full-suite + GOOS=windows build green. * Address #127 re-review: mirror normal flow for zero-question ask_user The zero-question fast path now records the (empty) request in the transcript and answers with an empty slice ([]string{}) instead of nil, so it matches the normal resolveAskUser flow and downstream sees a consistent Answers shape. (Skipped the suggested 'defer Ctrl+C quit until flush failures are acknowledged': blocking quit on Ctrl+C contradicts prompt-exit expectations, is a non-minimal UX change, and the edge is rare with graceful impact — the failure rows are already appended for the common non-exit cancel, and a missed checkpoint only makes that one /rewind unavailable.) --------- Co-authored-by: KRATOS <[email protected]> |

Session checkpoints & safe rewind: content-addressed blobs, atomic restore, file locking (#112)
* Session checkpoints & safe rewind: content-addressed blobs, atomic restore, file locking Module 4 of the runtime-core split. Scope: internal/sessions only. 3-way merged cleanly onto main's #106 Tag/Depth work (preserved); no new deps (filelock uses stdlib syscall); build/vet/-race/windows-cross-compile/full-suite green. - CaptureToolCheckpoint snapshots a tool's target files into content-addressed (sha256) blobs before a mutating tool runs; SnapshotForCheckpoint records file mode; oversize files are skipped, identical content deduped. - RestoreToSequence reverts to a target sequence: applies only the closest-to-target checkpoint per path, verifies each blob's sha256 before writing, preserves file mode, and confines paths with EvalSymlinks (no symlink escape). ApplyRewind runs restore+truncate+prune+marker atomically under one session lock. - Cross-process file lock (flock) serializes session mutations; Fork copies checkpoint blobs so a fork can rewind; writeMetadata uses a unique tmp suffix. FORWARD: this is the persistence layer; the CLI 'zero sessions rewind' and the TUI '/rewind' + pre-tool checkpoint capture wiring land in later modules. Exercised here by checkpoint_test.go / rewind_test.go. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]> * Address #112 review: capture-side confinement, atomic-only checkpoint API, Windows lock, test hygiene - [critical/human blocker] snapshotForCheckpoint now confines every capture target with resolveWithinWorkspace (same EvalSymlinks/no-".." guard as restore) BEFORE stat/read, so a traversal/symlink target can't read files outside the workspace into a blob. os.Stat failures are classified correctly: only os.IsNotExist -> Absent (restore deletes); permission/IO/symlink-loop -> Skipped (restore leaves alone), instead of treating every failure as Absent. Regression test added (TestCaptureRejectsTraversalTargets). - [major] SnapshotForCheckpoint unexported -> snapshotForCheckpoint: the blob writes and the referencing EventSessionCheckpoint must be committed atomically under one session lock, which only CaptureToolCheckpoint guarantees. Removes the unsafe snapshot-only external entry point (blob/event gap). - [major] Windows: real LockFileEx/UnlockFileEx (filelock_windows.go) replacing the no-op, so cross-process/cross-Store session serialization holds on Windows too. No new deps (x/sys already required for the unix flock). - [minor] checkpoint_test hygiene: check os.WriteFile/ReadDir/ReadFile/ReadEvents errors via helpers, add bounds checks before p.Files[0]/events[...] so setup failures fail at the source instead of panicking or passing spuriously. - rewind restore: documented the residual symlink-swap TOCTOU (boundary re-resolved immediately before the mutation; full closure needs openat2 RESOLVE_BENEATH / per-component O_NOFOLLOW, tracked for the CLI/TUI rewind-wiring work). build/vet/-race/full-suite + GOOS=windows build all green. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]> * Address #112 re-review: fail rewind on undecodable checkpoint payload [major] restoreToSequenceLocked silently continued past a checkpoint whose payload failed to decode, which let a NEWER checkpoint win for that path and restore a later state than the caller requested. Treat corruption as a hard rewind error. Regression test TestRestoreFailsOnCorruptCheckpointPayload (fails-open before, errors now). Re-review note: the earlier capture-target-validation (critical) and test bounds (minor) were already addressed in |

All relevant tests now pass. * fix(agent): make sandbox decision available synchronously on Result for permission events The recent change to invoke OnSandboxDecision asynchronously (to satisfy non-blocking requirement) broke the agent's immediate capture of the decision for building PermissionEvent after registry.RunWithOptions. - Add SandboxDecision *sandbox.Decision to tools.Result (not serialized). - Populate it on all sandbox-involved return paths in registry.RunWithOptions (sync, before/while firing async callback for observers). - In agent executeToolCall, use result.SandboxDecision for buildPermissionEvent (reliable ordering) instead of side-effect capture via the callback. - The async callback is still supported for any external OnSandboxDecision consumers. This fixes the two failing agent tests that were causing the cross-platform 'Smoke' CI jobs to fail on this PR: - TestRunEmitsPermissionEventForPersistentSandboxGrant - TestRunAppliesSandboxEvenInUnsafeMode All go tests now pass. --------- Co-authored-by: KRATOS <[email protected]> |
