Both caches age an entry by the lifecycle it describes: an open PR/MR by the short TTL (`_CACHE_TTL_SECS` for the payload, `_CHECK_TTL_SECS` for the chip), a **merged** one by `_TERMINAL_TTL_SECS` (six hours) and a **closed** one by `_CLOSED_TTL_SECS` (one hour — it can be reopened and keeps accruing discussion), because re-reading a finished pull request on the open-PR cadence for as long as its chip stays in a sidebar was one provider subprocess per finished PR per minute, forever. The payload TTL is decided from the payload itself through the same `_project_state` the chip projection uses (`_full_payload_ttl`), so the two caches cannot disagree about whether a URL is finished; the explicit refresh button and mutation invalidation still bypass both, and the turn-boundary force (`request_check_refresh_now`) still re-reads a closed chip (an agent can reopen one) but never a merged one (`_chip_refresh_due`). Those lifecycle clocks govern the chip cache and the full payloads that have no cheaper read (GitLab, registered plugins). A github.com full payload is instead REVALIDATED past the open TTL whatever its lifecycle: `_revalidate_pull_request` first issues small conditional REST GETs through `gh api -i -H If-None-Match` — `issues/{n}` (its ETag follows the pull request's `updated_at`: title/body/labels/lifecycle including a reopen, a push, reviews, comments) and, for an OPEN pull request only, `commits/{head_sha}/check-runs` plus `commits/{head_sha}/status` (CI hangs off the commit and never moves `updated_at`; check runs and legacy commit statuses are separate resources and the rollup renders both) — and only when any probe answers something other than `304` does the fanout run; all-304 re-stamps the cached entry instead. So post-merge comments and a reopen reach the panel within one open TTL for one rate-limit-free request. It is strictly 304-only: the first probe of a URL has no validator, answers 200, and only LEARNS the ETags (`_REVALIDATORS`, bounded, the two commit-level validators scoped to the head sha so a push cannot reuse the old commit's), a failed probe is "unknown", and nothing is ever judged unchanged by comparing bodies. Validators returned by an all-304 are committed at once; those returned by a 200 describe a payload the cache does not hold yet and are committed only after the full read that follows has succeeded, so a failed fanout can never pair the old payload with new validators (which would make every later probe re-stamp it as current). Re-stamping is also capped: each validator set remembers when its payload was last read in full (`read_at`), and past `_REVALIDATED_MAX_AGE_SECS` (the merged TTL, 6 h) one full read runs without probing and the validators are dropped so the next cycle learns a fresh set — the probes rest on GitHub moving the issue ETag for every rendered field, which the API does not promise, so a coverage gap degrades to bounded staleness instead of unbounded. `pulls/{n}` is deliberately not the probe (its ETag churns on the embedded repository counters), GitHub's GraphQL API — what `gh pr view` speaks — has no conditional requests, an authenticated 304 costs nothing on the primary rate limit, and `gh` exits 1 on a 304 so `_parse_conditional_get` reads the status line rather than the exit code. The merge pair moves no validator and stays with the chip protocol; an explicit refresh, a mutation invalidation, GitLab and registered plugins never probe. Full source payloads carry a normalized merge-state pair shared by both providers: `mergeable` is `mergeable|conflicting|unknown` (`''` when the provider omitted it) and `mergeStateStatus` uses GitHub's lowercased merge-state vocabulary extended with a GitLab-specific value (`clean|dirty|behind|blocked|unstable|draft|need_rebase|unknown|''`). GitHub maps `mergeable`/`mergeStateStatus` from `gh pr view` directly; GitLab derives `mergeable` from `detailed_merge_status` (falling back to legacy `merge_status`) and maps `detailed_merge_status` onto the shared vocabulary (`conflict`→`dirty`, `need_rebase`→`need_rebase` (kept distinct: on fast-forward-only projects a merge commit cannot unblock the MR, so it must not be conflated with `behind`), approval/CI/discussion/policy/security gates (including `status_checks_must_pass`, `policies_denied`, `security_policy_violations`, `merge_request_blocked`)→`blocked`, `ci_still_running`→`unstable`, unrecognized non-empty values→`unknown`). Both providers compute mergeability **lazily**: the first read of a pull request they have not evaluated recently answers "not known yet" (GitHub `UNKNOWN`, GitLab `checking`/`unchecked`) *and* is what starts the computation, so a single read reports a conflicting pull request as having no merge blocker at all. Each full fetch therefore re-reads the merge fields alone — `gh pr view --json mergeable,mergeStateStatus` / the GitLab merge-request endpoint, which is the only place `detailed_merge_status` is exposed — at most `_MERGE_STATE_REREADS` (2) times spaced `_MERGE_STATE_REREAD_DELAY_SECS` (0.8s) apart, dispatched inside the existing secondary fanout so the wait overlaps calls the request was already making. A value that is empty rather than unknown is never re-read (the provider omitted the field; re-reading cannot settle it), and an unsettled, failed, or malformed re-read degrades to `unknown` rather than raising — an unknown merge state costs one banner, never the panel. Settledness is judged on the **pair**, not on `mergeable` alone: GitLab settles `need_rebase` and its branch-protection gates in the detail field while `mergeable` stays `unknown`, so keying on `mergeable` would re-read a state the provider had already answered and then discard it. Provider CLIs run through `sandboxed_spawn_argv(..., mode="standard")` using absolute paths only: an explicit absolute `KIROCREW_GH_BIN` / `KIROCREW_GLAB_BIN` override, else the fixed well-known install dirs, else the ambient `PATH` (`provider_executable_candidates()`). The trust policy itself (candidate dirs, validation, strict mode) is single-sourced in `kiro_crew.github_runner` and re-exported here, so this panel, Issue Radar, and Code Review Sage can never drift apart. The default policy is *if the CLI works in the user's terminal, it works here*: the gateway user's OWN install is accepted — Homebrew/Linuxbrew/asdf symlink layouts included — and only provenance the user did not choose is refused, namely a binary (or ancestor) owned by another unprivileged account, anything world-writable (a world-writable *directory* is tolerated only when sticky — `/tmp`-style 1777, where only the owner may replace an entry, so the ownership check still decides), and anything inside the agent-writable project checkout or workspace root (`github_runner.agent_writable_roots()`, the one substitution vector the model controls; the same rule codex applies to its own sandbox helper). A gateway running as **root** is refused outright in BOTH modes, because every process it spawns — the agent's own shell included — would be root too, which makes the ownership and agent-tree checks vacuous. Requiring a root-owned copy instead made every stock `brew install gh` fail and pushed users into a `sudo cp` ritual for a CLI they had already installed and authenticated, so provenance was traded for containment: the provider child still gets only a minimal provider-scoped env, and every spawn is SEL-audited. `KIROCREW_PROVIDER_BIN_STRICT=1` restores the historical hardened rule for shared or multi-tenant hosts — canonical, symlink-free, root-owned and non-writable through every ancestor, `PATH` never consulted — and its setup error then names the privileged `/usr/local/libexec/kirocrew/` (or `/usr/libexec/kirocrew/`) copy to provision plus the override to point at it. The child receives a fixed system `PATH`, never the gateway/workspace `PATH`; `resource_limit_preexec()`, a minimal provider-specific environment, and host pinning remain enforced, and unrelated gateway/AWS/Slack credentials are not inherited. `github.com` and `gitlab.com` are always accepted; a self-managed GitLab instance is accepted only when the URL's exact `host[:port]` is a member of the operator's `dashboard.gitlab_hosts` allowlist (deny-by-default, config-only, never browser-supplied, no suffix or wildcard matching, `www.` not stripped, and a portless entry does not authorize an arbitrary port; an explicit `:443` is treated as absent on both sides so it matches the browser URL API, which drops the default HTTPS port). The allowlist is served from a process-cached snapshot refreshed at most once per 30s by `ensure_gitlab_hosts_loaded()`, which every async entry point awaits before validating a URL: the config read runs in a worker thread, never on the event loop, and the synchronous accessor that URL parsing and slot serialization use only reads the cached snapshot (empty before the first refresh, which fails closed). Refreshes are serialized behind a lock with a post-acquire freshness recheck, so a loader holding the pre-revocation config cannot install its snapshot after a newer one and re-admit a just-removed host for another interval. Each content change bumps `gitlab_hosts_generation()`, which `_ChatSlot._pr_source_links()` folds into its per-slot cache key alongside the message revision -- the synchronous scan can run before the first load, and without the generation that cold-snapshot rejection would stay memoized until the next message mutation, leaving a self-managed chip missing (or a revoked one present). A `glab` call to a self-managed host drops `GITLAB_TOKEN` from the child environment: that variable carries no host binding, so forwarding it would hand a gitlab.com credential to the self-managed server; such hosts authenticate from their per-host entry in glab's own config, still reachable via `GLAB_CONFIG_DIR`. gitlab.com keeps the ambient token. `host` is a REQUIRED argument for every `glab` invocation rather than a defaulted one: an omitted host raises instead of silently resolving to gitlab.com, so no future call site (including a mutation endpoint) can read or write an allowlisted self-managed MR on the public instance at the same project/IID. Because slot source-link extraction is synchronous and cannot load the snapshot itself, the owner WebSocket awaits `ensure_gitlab_hosts_loaded()` before its first `serialize_slots()` and again once per refresh round, pushing a slots update whenever the generation changes -- otherwise a newly authorized (or revoked) self-managed chip would wait for an unrelated message mutation. `GET /api/chat/slots` performs the same warm-up so a cold direct fetch is not missing those links either. A full payload's `url`/`number` identity always comes from the validated `SourceRef`, never from the provider's echoed `web_url`/`iid`/`url`: the browser submits that url back for refresh and thread resolution, so a hostile or compromised instance echoing a different merge request could otherwise steer an owner-authenticated call at an unrelated one. Each `glab` invocation pins `GITLAB_HOST` to the host `parse_source_url` authorized for that URL and re-checks it against the allowlist at spawn time, so a configured self-managed default in `glab` config cannot redirect bare API paths and a caller that skipped URL validation is denied rather than reaching an unauthorized instance. The dashboard-config GET exposes `gitlab_hosts` read-only (absent from the PUT allowlist) purely so the client knows which pasted links to surface as source tabs. Provider stdout is section-bounded at 1 MiB for metadata/checks, 2 MiB for discussions, and 4 MiB for diffs/changes; normalized full payloads are capped at 8 MiB. A global four-command semaphore covers full-source, direct-check, resolve, and sidebar work. Unique direct full/check tasks share a 16-task ceiling and a conservative 128 MiB retained-byte budget: full tasks reserve 64 MiB and checks tasks reserve 8 MiB until the underlying task terminates. Same-URL callers coalesce before admission, detached stale full fetches retain their leases, and a stale pre-mutation fetch plus its required fresh successor can coexist at the exact aggregate ceiling. Successful thread resolution advances that URL's cache generation and detaches older shared fetches so pre-mutation results cannot refill the cache or satisfy the post-resolution refresh. Secondary metadata endpoints degrade independently so core source details remain available, but every failed files, commits, discussion/thread, pipeline, job, or GitHub check-rollup request is named in `partialSections` before its data falls back to an empty section. GitHub's `statusCheckRollup` is never bundled into another `gh pr view` field set: `gh` resolves a `--json` field set atomically, so a fine-grained token without Checks read access would lose the fields it WAS authorized for — the full payload, the sidebar chip, and the checks poll all read the rollup through one isolated query (`_github_rollup_read`, which also carries `headRefOid`), and a rollup read that fails or that straddled a push (its head sha differing from the core read's) marks `checks` partial with an empty list instead of failing the read or rendering another commit's checks; provider page limits and overflow evidence use the same deduplicated markers. Native Windows is not refused by a platform check of its own: it has no OS-level provider sandbox backend, so it reaches the same no-backend policy a backend-less Linux host does — `sandboxed_spawn_argv` fail-closes and the read is refused unless the operator set `agent.sandbox_allow_unsandboxed_exec`, whose refusal text names that opt-in. With the opt-in set, provider commands (reads and the PR/MR mutations alike) do spawn on Windows, under the same non-sandbox bounds every host keeps: the `{gh, glab}` allowlist, the validated absolute executable, the minimal provider env with a fixed system `PATH`, host pinning, the output caps, and the SEL audit. Every provider execution emits credential-free SEL `invoked` plus `completed`/`failed` lifecycle events; policy and provenance rejections emit `denied`. The critical `invoked` append is shielded and awaited on a worker thread before spawn, preserving audit-or-deny ordering without blocking the gateway event loop; cancellation waits for that worker, pairs a landed `invoked` event with `failed/request_cancelled`, and never spawns, while other terminal events are best effort. Events contain only the logical provider and coarse reason, never argv, URL, repository, output, environment, credentials, thread id, or exception text. Sidebar refreshes run outside slot serialization with inflight deduplication, a 16-task pending ceiling, one-TTL overflow backoff, and a 512-entry status cache. Scheduling requires an exact dashboard-owner request. Cached check state is otherwise only repopulated at WebSocket-connect and slots-GET time, so each owner WebSocket connection additionally runs a background refresh driver that re-schedules refreshes for its currently-rendered sidebar chip URLs (`DashboardState.source_link_urls()` — the first `_SERIALIZED_SOURCE_LINKS_PER_SLOT` links of every slot) once per cache TTL (`CHECK_STATUS_TTL_SECS`, sleeping exactly one TTL so each round finds the previous round's entries just expired — one provider fetch per URL per TTL, coalesced across tabs by the inflight dedup; a merged or closed chip is skipped by the same `_chip_refresh_due` gate until its terminal TTL lapses); without it a PR merged or a CI run completed after page load would keep its stale connect-time chip until a full reload. The driver is owner-gated (never created for non-owner connections), cancelled with the connection, and advances a per-round starting offset by the pending admission cap (`CHECK_STATUS_PENDING_MAX`) each round so that when the number of stale chips exceeds the cap the admitted window rotates across every chip within `ceil(len/cap)` rounds instead of the same slot-order prefix winning every TTL and starving newer slots' chips indefinitely. Each round's work is individually guarded so a transient failure is logged and the loop continues rather than the driver dying silently and reverting to frozen chips. Generic slot serialization and broadcasts omit cached `state`/`ci`; owner HTTP and WebSocket snapshots opt in, and changed statuses trigger a debounced generic update followed by an owner-WebSocket-only overlay. `_ChatSlot` retains only the first 64 unique durable source links and stops scanning at the cap; `to_dict()` exposes up to three sidebar chips as `{url, provider, number}` to all authenticated callers and adds the whole cached chip-status entry — `{state?, ci?, mergeable?, mergeStateStatus?}` — only at an owner-authorized serialization boundary. `state` is `open|draft|merged|closed` and `ci` is `running|passed|failed` when known; the merge pair uses the shared merge-state vocabulary above and is present only once settled. Both providers derive `state` with terminal states outranking draft (a GitLab MR keeps `draft` set after being closed as a draft, so draft is reported only while the MR is `opened`), and a provider state outside the known set (e.g. GitLab `locked`) yields no `state` rather than a mislabeled `open`. `ci` rolls a GitLab pipeline status up the same way GitHub's check conclusions roll up: any failure fails, anything still in flight runs, and a terminal non-failure -- including a wholly `skipped` pipeline -- passes, so a skipped pipeline settles instead of spinning. Pipeline-level `manual` is the one deliberate split from the job-level bucket: a pipeline in `manual` is blocked awaiting a required manual job, so it reports `running` rather than green, while a single `manual` job among finished ones still buckets as skipped -- unless it carries `allow_failure: false`, which makes it a required gate and therefore pending. GitLab's chip status reads `head_pipeline` from the merge-request payload and falls back to the MR pipelines list only when that field is absent. GitHub's chip refresh pairs its core-field read (`state,isDraft,mergeable,mergeStateStatus,headRefOid`) with the same isolated rollup read, concurrently; only the core read is load-bearing — a rollup that fails or describes a different head degrades to an internal ci-unavailable marker that `_refresh_check_status` strips before caching, keeping a previously known `ci` glyph rather than erasing it (the same keep-known posture the full-payload write-through applies when `checks` is partial), while a successful rollup with zero checks still clears a stale glyph. Because the chip entry is spread whole, a refresh in which only the merge pair settles also counts as a status change and triggers the same debounced generic update plus owner overlay. This module also owns the TRANSCRIPT-SEARCH seam for provider ids: `SourceProviderPlugin` carries an optional `search_ref(token) -> (canonical, alts) | None` hook (getattr-discovered, like `path_markers()`), `source_search_ref()` fans out across the registered plugins and asks each registered plugin until one answers and hands that answer through UNVALIDATED, without reading `alts` itself (the shape checks belong to the single normalizer, whose guard also wraps this collector because it IS the resolver core calls, while a raising hook is caught per provider here); the FIRST plugin to ANSWER wins, for every token shape, and the spellings it contributes are bounded once in core by `_MAX_SEARCH_REF_SPELLINGS` rather than by a collector-side ceiling that would drift from it. There is deliberately no cross-plugin merge: one would exist to serve two registrants holding a real item at the same number, and this repo registers no provider at all, so it would be surface no code path can reach — additive if a second registrant ever appears. `register_source_provider()` additionally publishes that collector downward into `history_search.register_search_ref_resolver` — dashboard → core, at registration rather than from a route handler, so the non-HTTP callers of `parse_search_query` answer identically. Casefolding, dedup and the per-provider spelling cap belong to `history_search._provider_search_ref`, the single normalizer; `reset_source_providers_for_tests()` unpublishes the resolver alongside the plugin registry. - `server.py` — app factory, route registration, startup, SPA fallback middleware for React Router, `/api/ws` WebSocket route, token auth middleware, loopback-only binding (`127.0.0.1`). Fires background MCP probe at startup via `asyncio.create_task()`. Honors `agent.yolo=true` config at startup via `_apply_startup_yolo()` — attempts SEL audit first and only activates dashboard YOLO (6h TTL) if the audit succeeds (fail-closed). diff --git a/src/kiro_crew/context.py b/src/kiro_crew/context.py index 9bff2af5080..3c8ecf38bd2 100644 --- a/src/kiro_crew/context.py +++ b/src/kiro_crew/context.py @@ -667,31 +667,139 @@ def _is_marker_ignorable(ch: str) -> bool: ) -def _scrub_member_payload(text: str) -> str: - """Neutralize member-authority markers in an untrusted payload. - - The payload is first NORMALIZED — NFKC-folded (so fullwidth/compatibility - confusables like ``［ＰＥＲＭＡＮＥＮＴ ＲＵＬＥＳ］`` collapse to their - ASCII forms), then Unicode default-ignorables dropped and every dash folded - to ASCII ``-`` — and the normalized copy is what gets injected, so a - confusable forgery (``[PERMANENT RULES‐``) cannot slip past the ASCII - patterns.
