fix(sessions): capture freeform apply_patch checkpoints (#1183)
* fix(sessions): capture freeform apply_patch checkpoints Freeform apply_patch arguments are raw patch text, but both checkpoint paths passed them to json.Unmarshal and dropped the error, so they found no mutation targets and recorded no checkpoint. The tool still executed, leaving rewind unable to restore the edit. Resolve targets through a shared agent.CheckpointTargets helper that prepares freeform input on the registered built-in apply_patch, exactly as executeToolCall does. This keeps absolute patch headers workspace-relative (rewriting them and setting cwd) instead of handing absolute paths to the checkpoint layer. Non-freeform calls now use the same tolerant decoder as execution, so the two cannot disagree. Covers the CLI, spec-draft, and TUI capture paths. Fixes #1162 * test(sessions): canonicalize freeform absolute-header fixtures t.TempDir returns the symlinked /var spelling on macOS and short names on Windows, while the apply_patch tool resolves the physical root. The absolute-header cases must build the header from the resolved root, as the repo's cross-platform test guidance requires. |

chore: move repository references to Twigpine/zero (#1105)
Update the Go module path, imports, install scripts, docs, workflows, packaging and action defaults from Gitlawb/zero to Twigpine/zero. The npm scope (already @twigpine/zero on main, with its @gitlawb/zero migration notes), LICENSE, action author, the OpenGateway provider and historical CHANGELOG links are unchanged. The X-AIMLAPI-Integration-Repo header keeps Gitlawb/zero: it is what AIMLAPI sees for attribution, so changing it needs a maintainer's yes. docs/INSTALL.md keeps `go install github.com/Gitlawb/zero/...`, because every tagged release so far declares that module path. The Homebrew formula comment names the Twigpine/homebrew-tap tap. Co-authored-by: Claude Opus 5.5 <[email protected]> |

fix(mcp): forward image tool results on the existing image channel (#1077)
* fix(mcp): forward image tool results on the existing image channel Recreated from Gitlawb/zero#1012 (approved but unmerged). Original: euxaristia/zero:feat/823-forward-mcp-images * test(mcp): pin the pre-decode encoded cap and MIME sniffing guards Adds the two reviewer-requested tests for the untrusted-input boundary: - TestOverCapEncodedPayloadIsRejectedBeforeDecoding: a payload one byte over EncodedLen(MaxImageBytes) is rejected and the decoder is never called, so a hostile server cannot force arbitrary decode work. - TestDeclaredMimeTypeDisagreeingWithSniffedBytesIsDropped: an HTML payload declared as image/png is sniffed from its bytes and dropped rather than forwarded to the provider as an image. Both mutations (removing the cap, trusting the declared mimeType) were verified to turn their test red locally. |

feat(sandbox): unify command execution and enforcement (#781)
* feat(sandbox): unify command execution and enforcement * test(sandbox): make platform contracts portable * fix(sandbox): close execution lifecycle races Bound retained interactive output, preserve interruption state, and start workspace observation before process launch. Protect active runtime roots with cross-platform leases, capture transient protected-path creation events, and restore process attributes after PTY fallback. * fix(sandbox): restore strict macOS isolation Remove Seatbelt host-local network allowances after native validation showed localhost filters can reach host interfaces. Track process reap completion so retained sessions cannot signal a stale numeric PID. |

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. |

feat: gate project-scoped hooks, plugins, and MCP servers behind workspace trust (#529)
* feat(workspacetrust): add exact-match trust store for project config gating * feat(hooks): add ExcludeProject option to LoadConfig * feat(plugins): add ExcludeProject option to Load * feat(cli): gate project hooks and plugins behind workspace trust Trust check lives inside newHookDispatcherWithExtra and activatePlugins (fail-closed by construction); trustRoot is the original launch dir so a --worktree run inherits the source repo's trust. Callers OR the skip reports and emit one combined stderr notice. * feat(cli): add zero trust command (trust/list/remove) * fix(review): key spec-draft trust on the original launch dir; cover trust CLI edge branches Spec-draft runs (zero exec --use-spec --worktree) passed the reassigned worktree path as trustRoot, dropping a trusted repo's project hooks (fail-closed, but breaks worktree-inheritance). Thread the captured pre-worktree trustRoot into execSpecDraftRun. Add tests for the trust 'remove' too-many-args and --help branches, and a resolveTrust comment noting the per-chokepoint check must not be hoisted to callers. * test(cli): end-to-end trust-gate coverage through agent.Run and exec --worktree Drives the real agent loop with a fake tool-calling provider so a project beforeTool hook actually fires (or is gated away) through production code: gate blocks a tool call via agent.Run, and --worktree / --use-spec --worktree key trust on the original launch dir. All three are load-bearing (RED when the gate or the trustRoot threading regresses). * style(cli): gofmt struct alignment in exec_spec.go * fix(workspacetrust): compare stored trust entries literally, no symlink re-resolution External adversarial review (codex) found a false positive: IsTrusted re-normalized stored entries on every check (Abs+EvalSymlinks), so a trusted path later replaced by a symlink to attacker content re-resolved to the new target and matched. Stored entries are already canonical (normalized once at Trust time); compare them as literals and only normalize the incoming query. Add a regression test for the symlink-retarget case. * feat(mcp): gate project-scoped MCP servers behind workspace trust Closes the P0 an external adversarial review (codex) found: project ./.zero/config.json stdio MCP servers spawned before the hook/plugin gate, an ungated arbitrary-execution path that could also self-trust the workspace. Add ExcludeProject to config.ResolveMCP (skips the project layer) and thread a fail-closed trust check into every MCP spawn site (exec, TUI setup+refresh, mcp tools list, mcp check); reporting sites stay ungated. Verified the sole server-command exec (mcp/client.go) is reachable only through the now-gated RegisterTools paths. * test(cli): cover default-mode beforeTool firing through the trust gate Assert a project beforeTool hook fires in the default auto and ask permission modes (not only under unsafe), and is blocked when the workspace is untrusted, so the gate is verified in the mode a normal run actually uses. * docs(cli): note MCP servers in zero trust help text and doc comment The gate covers project hooks, plugins, and MCP servers, but the help string and runTrust doc comment listed only hooks and plugins. * test(cli): make workspace-trust tests portable on macOS and Windows setTrustConfigRoot set HOME on darwin, but config.UserConfigDir is XDG-first there (=$HOME/.config), so tests wrote trust.json and user hooks.json where the code never read them; set XDG_CONFIG_HOME on every non-Windows platform instead. writeMarkerHook shells out to /bin/sh, absent on Windows, so its trusted-case marker never appeared; skip it there like writeMarkerHookScript already does. TestRunTrustAddThenList compared `trust list` output (canonicalized via EvalSymlinks) against the raw cwd, which diverges on the Windows runner's 8.3 short names (RUNNER~1 -> runneradmin); compare the resolved path, and add TestRunTrustListShowsCanonicalPath to exercise that via a symlink on any platform. * feat(cli): surface the project MCP skip in the workspace-trust notice Project MCP servers were dropped silently in an untrusted workspace: the trust notice covered hooks and plugins but not MCP, and app.go discarded the resolveTrust error. registerMCPToolsForWorkspace now returns a trustSkip, gated on a new projectMCPConfigExists check plus the previously-dropped store-read error, and emitTrustNotice is variadic so the exec, spec-draft, interactive, and `mcp tools list` paths all fold in the MCP skip. The skip drives the notice only; the gate stays on resolveTrust/excludeProject, so a trusted workspace is unaffected and an untrusted one still fails closed. * fix(cli): print zero trust --help to stdout with a success exit zero trust -h/--help/help routed usage to stderr with the usage exit code, unlike every other subcommand (mcp, sandbox, skills, cron, ...) which prints help to stdout and returns success. Align it; the unknown-subcommand path still writes to stderr with the usage exit code. * fix(cli): gate oauth MCP login and surface mcp-check trust notice Two project-scoped MCP activation sites were left outside the workspace trust gate. zero mcp oauth login loaded a project-defined OAuth server from an untrusted workspace and ran the full discovery/registration/token-exchange flow against its configured URL. Gate resolveOAuthServer with resolveTrust so an untrusted clone's ./.zero/config.json OAuth server is dropped before login, and emit the same one-line trust notice the other spawn sites use. zero mcp check already gated the project layer but discarded the trust-check result and never emitted the notice, so a gated project server read as a bare "not configured". Emit the notice on the not-found branch. The three remaining ungated resolveMCPConfig(cwd, false) sites (backends doctor/snapshot and the extensions listing) are enumeration-only and stay ungated. * test(cli): adapt MCP startup-skip tests to two-arg resolveMCPConfig --------- Co-authored-by: Kevin Codex <[email protected]> |

feat: context-aware compaction + usage gauge for all models (#332)
* fix(agent): enable auto-compaction for all models, not just registered ones Auto-compaction keys off the model's context window (enabled = ContextWindow > 0), resolved only from the curated registry. Unregistered models — GPT-5/Codex, xAI, Ollama-cloud, custom endpoints — resolved to 0, so both the proactive (~80%) and the reactive post-overflow compaction were silently disabled and long sessions overflowed. - TUI modelContextWindow now also consults live-discovered windows (accurate for proxy/custom models once /model has discovered them); unknown still returns 0 so display gauges show no guessed denominator. - New modelregistry.AgentContextWindow applies a positive FallbackContextWindow (200k) ONLY on the compaction-enable path (TUI run + CLI exec/spec), so compaction is on for every model while display stays accurate-or-empty. Exact windows always win. * feat(tui): show context usage (used / total + % gauge) for all models from launch The sidebar/status-line context gauge only shows a total + fill % when the active model's context window is known. For proxy/custom models (GPT-5/Codex, xAI, Ollama- cloud) the window isn't in the registry, so it showed only a used-token count. Warm model discovery for the active provider in Init() (background, non-blocking) so the active model's window is learned at launch and the gauge renders 'used / total tokens' + the fill % for every model — not just catalogued ones. Builds on the discovered-window resolution from the compaction fix. * fix(tui): address review — agent fallback on model-switch + active-provider window - Apply modelregistry.AgentContextWindow to /model and /mode pre-switch compaction requests (TargetContextWindow), so the 'compaction for all models' behavior also covers undiscovered/custom switch targets, not just the active run. - Scope the live-discovered context-window lookup to the active provider first (then others), so a model ID shared across providers resolves to the provider in use rather than an arbitrary match. - Tighten the resolution test to compare against the registry's actual gpt-4.1 window instead of != FallbackContextWindow. * fix(cli): give provider-discovered context windows precedence in headless exec Address the remaining review point: CLI exec/spec runs collapsed every uncatalogued model to the 200k fallback, ignoring its real window. resolveAgentContextWindow now, on a registry miss, queries the provider's live model list (resolving the credential from inline/stored/env) to get the model's actual context window before falling back. Discovery runs only on a registry miss (catalogued models pay no latency), is bounded by a 5s timeout, and degrades to the fallback on any error so a headless run is never blocked or failed. |

token efficiency: lossless cost accounting + minified file reads (read_minified_file) (#256)
* token efficiency: lossless cost accounting + minified file reads Two complementary improvements to how Zero handles tokens. ACCOUNTING — make cost measurement lossless and correct: - Carry all five token dimensions end-to-end (input, cache-read, cache-write, output, reasoning) in one Usage; add CacheWriteTokens (cache creation), which the Anthropic adapter previously parsed then discarded. - Price cache-writes at their premium rate (Anthropic 1.25x input, derived per model). Regression-safe: a model without the rate bills cache-write at the input rate exactly as before. - Persist cache-read/cache-write/reasoning in EventUsage so `zero usage report` reconstructs the SAME cost as the live tracker instead of over-pricing cache-heavy sessions. A single EventUsagePayload writer is paired with the reader so the JSON keys can't drift. - Add a live context-window gauge to the status bar (used/window + percent, graded green/amber/red) using the last request's input tokens. REDUCTION — read_minified_file, a dense token-cheap file view: - New internal/minify package + read_minified_file tool returning a comment-free, line-number-free view: Go via the real go/parser AST; C/Java/CSS/SCSS/LESS/ Python via a string-aware comment lexer (handles strings, char literals, triple-quotes, Java text blocks, Python f-strings incl. 3.12 same-quote nesting). Every other language falls back to whitespace-only, so the stripper can never corrupt content. - ~32% fewer tokens on a realistic multi-file read; +~102 fixed tokens for the tool schema, recovered many times over by a single subsystem read. Tests: cache-write pricing + fallback, lossless persistence round-trip, the context gauge, comment-stripping golden cases per language (comment-chars in strings, Java text blocks, Python f-string nesting, CSS has no //), and the unsupported-language safe fallback. gofmt / vet / build / -race all green. * specialist: register read_minified_file in the tool registry + read-only sets Smoke caught TestKnownToolNamesMatchCoreRegistry drifting once read_minified_file joined the core read-only tools: the specialist tool allowlist (knownToolNames), the read-only/edit/execute categories, and the read-only auto-approve set did not list it. It is a read-only companion to read_file, so it belongs alongside read_file in all of them; updated the default-allowlist test accordingly. |

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.

Edit safety: file read/write tracking, external-modification detection, post-apply hooks (#172)
* Edit safety: file version tracking, conflict detection, hook wiring
Phase 1 — FileTracker (internal/tools/file_tracker.go): per-session
map[absPath]{sha256, size, mtime}; CheckConflict flags drift only against
a known baseline, so first-touch writes are unaffected. nil = no-op.
Phase 2 — external-modification detection: read_file records the
whole-file baseline; edit_file and write_file --overwrite refuse to
clobber a file whose on-disk content drifted from it and tell the model
to re-read first, then re-baseline to what they wrote. apply_patch
forgets the files it rewrote (git apply has its own context guard).
Threaded via RunOptions/agent.Options FileTracker, built once per session
in the exec, spec, and TUI paths.
Phase 3 — post-apply validation via hooks: the dormant hooks.Dispatcher
is wired into executeToolCall. beforeTool hooks can veto a call
(DenialHookBlocked); afterTool hook output is scrubbed and surfaced to
the model. DispatchOutcome now collects hook stdout/stderr. Per-session
dispatcher built from merged user+project hooks.json; fails open and runs
nothing until a hook is configured.
* edit-safety: address review — fail closed on read, redact hook reason
- write_file overwrite: if a tracked file cannot be re-read to verify it,
fail CLOSED (refuse the overwrite) instead of silently proceeding — the
read error previously skipped the conflict check and could clobber an
externally modified or replaced file.
- blockedByHookResult: scrub outcome.Reason through redaction before placing
it in model-visible ToolResult.Output; this intercepted path bypassed the
registry's normal output-redaction boundary.
- TestHashContentIsStableAndDistinguishing: compare separately stored hashes
so the stability check is not a same-expression comparison (SA4000).
* edit-safety: flag ToolResult.Redacted when hook output is scrubbed
appendHookFeedback now reports whether scrubbing changed the afterTool
feedback, and blockedByHookResult reports whether it scrubbed the reason;
both set ToolResult.Redacted so the hook-intercepted paths match the
registry's redaction contract. Adds tests asserting a secret-bearing hook
reason/feedback is scrubbed and flips Redacted.

Sound / completion notifier: terminal bell + OSC-9 on turn completion & awaiting-input (#149)
* notify: dep-free terminal bell / OSC-9 completion notifier * config: notify.mode + notify.focusMode (validated, default off) * exec: --notify/--no-notify + completion notify on stderr * tui: focus reporting + completion/awaiting-input notifications * notify: fire on exec --use-spec completion; headless ignores focus; gate focus-reporting on enabled * notify: validate --notify value, skip notify on empty ask_user, deterministic resolver tests Addresses #149 review (CodeRabbit + @Vasanthdev2004): - parseExecArgs rejects an invalid --notify value (only off/bell/notify/both), so a CLI typo errors early instead of silently running with no notification. - TUI OnAskUser fires AwaitingInput only when len(request.Questions) > 0 — a request with no questions auto-resolves without prompting, so the bell/desktop notification was a false positive. - notify resolver tests pass Env: map[string]string{} so Resolve does not fall back to os.Getenv (deterministic, not ambient-env dependent). |
