fix(dashboard): show public-repo PR/MR chip status to any dashboard user

[RohanK6]

Problem / Motivation

Sidebar session rows render PR / MR / issue chips, but the lifecycle status (merged / closed / open / draft) and the CI rollup glyph are stripped for any dashboard connection not classified as the configured owner — even when the repository is public, where that same status is world-visible on the provider's website.

The status pipeline was double-gated on is_owner_dashboard_request:

• dashboard/ws.py — the periodic chip refresh loop and connect-time refresh ran only for an owner connection, so a non-owner never populated the chip-status cache.
• dashboard/state.py — the status-bearing slots frame was sent only to owner WS clients.

is_owner_dashboard_request returns true only when the token subject equals owner_id. A dashboard session minted before KIROCREW_OWNER_ID was configured carries a local-app / local-startup subject for its whole life (the token re-mints from the incoming subject on refresh), so once an owner exists that session is denied owner status and every chip renders as a bare number — uniformly across GitHub, GitLab, and Jira.

Why it matters

For a public repo the PR's merge/close/CI state is not sensitive — it is visible to anyone on the provider website. Withholding it from a legitimate authenticated dashboard user provides no confidentiality benefit while removing the single most useful signal the chip carries (is this PR merged / closed / green). The symptom reads as a regression even though the chip code never changed — what changed was the session's relationship to owner_id.

What changed (motivation → approach → change)

Symptom: public-repo PR/MR chips lose their status for a non-owner dashboard session. Root cause: status is gated purely on connection-owner identity, never on whether the underlying repo is public. Change: gate chip status on repository visibility in addition to owner identity.

• Owner → status for every repo (public and private), unchanged.
• Authenticated dashboard user (non-owner) → status only for a known-public repo.
• Private / not-yet-known repos → owner-only (fail closed).
• App tokens → no status at all (scope unchanged).

Implementation:

• New per-repo visibility cache (public / private / unknown) in handlers/source_providers.py, keyed provider|host|owner|repo, with a long TTL, a bounded fire-and-forget fetch (gh repo view --json isPrivate / glab api projects/... — GitLab internal is treated as non-public), inflight dedup, and a fail-closed reader is_repo_public.
• A dashboard_user gate threaded through _project_source_links and the serialize_slots / to_dict / source_links_payload chain.
• The general slots broadcast is enriched with public-repo status (SSE and WS both run on dashboard-user tokens); app-token frames are stripped of the credential-backed status keys in filter_slots_for_app so no app scope can receive it.
• The periodic check-status + visibility refresh driver now runs for any authenticated dashboard connection, not only the owner (TTL + inflight dedup keep it to one provider fetch per URL/repo per TTL).

Tests

• New test/test_public_repo_chip_status.py (16 tests): is_repo_public reader; GitHub/GitLab visibility fetch + fail-closed on error; refresh keeps prior known value on failure; scheduler repo-dedup + TTL + issue/Jira skip; and the full _project_source_links gate matrix — owner/private, dashboard-user/public, dashboard-user/private, dashboard-user/unknown (fail-closed), app-token, and issue link.
• Updated test/test_dashboard_state_ws.py: public-repo status now rides the general/SSE frame; owner still gets the dedicated full-status frame; a new test proves app-token frames are stripped of status; the refresh-loop tests now assert app tokens never start the driver while a non-owner dashboard user does (with visibility refresh scheduled).

Manual verification

N/A — unit coverage is sufficient. The change is a backend gate with no new UI; the gate matrix, the broadcast routing (owner / dashboard-user / app-token), and the visibility cache are all exercised by the automated tests above. Local gates all green: pytest (touched suites), isort, flake8, mypy src/kiro_crew/, and the baselined black gate.

Pattern harvest

Rule candidate: semgrep
Pattern: when a permission gate is widened from owner-only to a broader audience (here a non-owner dashboard user, gated on repo visibility), EVERY code path that acts on the gated resource must apply the same gate — not only the data-serving path but every scheduling-time credentialed side-read it triggers. In this PR the identical non-owner-drives-credentialed-read-on-private-repo leak reappeared at four distinct sites (ws.py connect scheduler, ws.py periodic refresh loop, chat_handlers.py GET /api/chat/slots, state.py turn-completion refresh) because the visibility gate was added to the render/serialize path but each independent schedule_check_refresh / request_check_refresh_now call site had to be gated separately. Generalized rule: flag a call that fans a user-reachable request out to an operator-credentialed subprocess/API read (schedule_check_refresh, request_check_refresh_now, gh/glab invocations) when it is reachable by a non-owner principal but not guarded by the same positive authorization predicate (is_repo_public(url) is True / owner check) that gates the corresponding response projection. Companion rule: a positive authorization GRANT (not only a denial) must emit an SEL audit event.

Design-level review of d7d2f20a596bef2114b7208bfe66f688dc984e9d via the fork AI-review pipeline — updated in place on each push. A BLOCK verdict blocks PR readiness; PASS/CONCERNS are advisory.

Design-Verdict: CONCERNS

Sound public-visibility gate, but it side-steps the stated root cause and buys a two-cache coherence problem that already took 15 rounds of race patches.

Watch

• The motivating regression is only partially fixed. The description's harm is a session whose token "carries a local-app / local-startup subject for its whole life" once an owner exists. Every refresh driver in this diff stays owner-gated (if owner_request: in ws.py, if include_check_status: in chat_handlers, if not self._owner_ws_clients: return), so that misclassified session gets public status only while a correctly-classified owner window is concurrently open to warm the 60-second-TTL caches — alone, its chips stay bare, and private repos stay bare for it regardless. The subject re-mint that never re-evaluates against the now-configured owner_id is the root cause and remains untouched; fixing it would restore full status to the legitimate operator with almost no code.
• Coherence between two independently-TTL'd caches is now a security property, maintained by force-generations, synchronous pre-invalidation, and lockstep revalidation at three writer sites. The PR's own pattern-harvest concedes the identical leak reappeared at four call sites; the next status writer added must remember the same dance or reopen the window.

Suggestions

• Make coherence structural instead of protocol-based: fetch the repo's visibility inside the status-refresh task and publish it atomically with (or inside) the status cache entry, so status and the flag authorizing it can never diverge — this deletes _visibility_force_gen, the pre-invalidation, and the per-writer lockstep calls.
• File the token-subject heal (re-evaluate/re-mint the session subject against current owner_id) as the follow-up that actually closes Sidebar PR/issue chips drop status (merged/closed/CI) for non-owner dashboard users on public repos #6786 for a solo misclassified session.

Premise-level review of d7d2f20a596bef2114b7208bfe66f688dc984e9d via the fork AI-review pipeline — why this exists and whether the shipped surface is the smallest honest version. Updated in place on each push. A BLOCK verdict blocks PR readiness; PASS/CONCERNS are advisory.

I have enough to write the review. Key finding confirmed: the codebase already recognizes the exact root cause the PR names — a pre-owner session stuck on a local-app/local-startup subject — via STALE_OWNER_SESSION_CODE / stale_owner_session_response (source_providers.py:4945, 4954), whose designed remedy is re-authentication.

First-Principles-Verdict: CONCERNS

#6786 is an owner's stale-subject session misclassified as non-owner; this ships a public-repo visibility subsystem for all non-owners and leaves that reporter's private-repo chips still bare.

What this change ships

Intent: restore/expand PR-MR chip status for authenticated dashboard users — typed fix, but fundamentally an ADDITION (a new trust-boundary decision: non-owners may see public-repo status).

1. Non-owner dashboard user sees PR/MR lifecycle+CI status for known-public repos — symptom-level (see below)
2. Per-repo visibility cache + is_repo_public reader — justified (supports item 1)
3. schedule_visibility_refresh + force/generation race machinery — justified (its concurrency is Design/correctness lane, not mine)
4. Visibility read now paired to every status write/refresh (connect, periodic, turn-boundary, both writers) — justified timing consequence
5. SEL grant audit _audit_public_status_grant — justified (records a real boundary crossing)
6. SEL deny audit _audit_public_status_denied — inherited symmetry
7. _CHIP_STATUS_KEYS enumerated projection replacing **cache splat — justified hardening
8. _strip_source_link_status app-token strip — justified defense
9. Split _slots_list (bare, SSE) vs _slots_list_ws (enriched) — justified (SSE has no per-app filter)
10. dashboard_user threaded through serialize chain — justified plumbing

Watch

• Root cause/framing: description concedes "what changed was the session's relationship to owner_id" and Fixes Sidebar PR/issue chips drop status (merged/closed/CI) for non-owner dashboard users on public repos #6786, yet the fix never restores that owner's own session — for a private repo the Sidebar PR/issue chips drop status (merged/closed/CI) for non-owner dashboard users on public repos #6786 reporter still sees bare chips. The nameable cause (stale subject; already labelled by stale_owner_session_response, source_providers.py:4954) sits in the auth layer, so a full fix may be out of scope — but then this only partially fixes Sidebar PR/issue chips drop status (merged/closed/CI) for non-owner dashboard users on public repos #6786, and that gap should be stated.

Subtractions

• Drop _audit_public_status_denied (state.py:473): a read that omits an optional chip decoration is not a denied request — the user still receives the slots frame. Its stated justification is "Symmetric to the grant audit," which is analogy; the grant audit already records the boundary crossings that matter.

Opus 4.8 Review (fork) — ✅ no blocking findings

Reviewed d7d2f20a596bef2114b7208bfe66f688dc984e9d via the fork AI-review pipeline; updated in place on each push.

Review details

I've verified enough. The base file confirms the codebase convention: _trim_check_cache explicitly prunes every parallel map (_check_generations, _check_forced_at, _check_flap, _check_force_pending) with the comment "so these maps cannot outgrow the cache." The diff adds two new per-key bookkeeping dicts that break that convention.

Assessing the three candidates:

• Candidate 1 (_visibility_force_gen unbounded): grounded. Bumped per-repo on every force=True refresh (diff), and _trim_visibility_cache trims only _visibility_cache, never _visibility_force_gen — diverging from the sibling _trim_check_cache which prunes all its parallel maps. Real but low-magnitude (per-repo). Advisory.
• Candidate 2 (audit dedup dicts unbounded): grounded and stronger — keyed per-URL, no cap and no eviction anywhere, written on the per-broadcast serialization path. Advisory.
• Candidate 3 (phantom SEL events): the decision is genuinely computed as part of building the WS frame delivered to any dashboard-user; deduped; audit-fidelity nuance, not a concrete wrong outcome. Does not clear the bar. Drop.

Neither surviving finding is a security boundary, crash, or data-loss — both are advisory. No Step-2 additions warranted; the security gate logic is fail-closed and extensively tested.

Two advisory findings: new per-key bookkeeping dicts on the hot broadcast/refresh path lack the eviction every sibling _check_* map is given.

FINDING — src/kiro_crew/dashboard/state.py:2214 — _PUBLIC_STATUS_GRANT_AUDIT/_PUBLIC_STATUS_DENY_AUDIT are written one entry per distinct source URL on every push broadcast and never evicted (no cap, no trim, no drop on slot deletion), so a long-running gateway leaks one float per distinct PR/MR URL ever serialized — unlike _visibility_cache/_check_cache which are bounded → Fix: cap + evict-oldest (or prune expired-window entries) mirroring _trim_check_cache.

FINDING — src/kiro_crew/dashboard/handlers/source_providers.py:5453 — _visibility_force_gen[key] is bumped on every force=True refresh but _trim_visibility_cache bounds only _visibility_cache, leaving one permanent int per distinct repo ever force-refreshed, diverging from _trim_check_cache which explicitly prunes its parallel maps "so these maps cannot outgrow the cache" → Fix: in _trim_visibility_cache, drop _visibility_force_gen keys absent from _visibility_cache and _visibility_inflight.

GPT 5.6 (BLOCKING) — fixed

source_providers.py stale-public-authorizes-private hole. Fixed at root cause:

• is_repo_public now TTL-expires a cache entry: an entry older than _VISIBILITY_TTL_SECS returns None (fail closed), so a public flag can never authorize status forever.
• _refresh_repo_visibility no longer extends a stale value: on a failed read it keeps the prior value without resetting the timestamp, so a repo that flips public→private while its visibility read keeps failing ages out from its last successful read and fails closed within one TTL. A cold failed read records unknown.
• Regression tests added: test_stale_public_entry_reads_as_unknown, test_failed_refresh_does_not_extend_stale_public, test_cold_failed_refresh_records_unknown.

Design / First-Principles (advisory CONCERNS)

• Widen-then-subtract fail-open at the app-token boundary — addressed by code: the attach in _project_source_links now projects only an explicit _CHIP_STATUS_KEYS allowlist instead of splatting the raw cache dict, so a future cache field cannot silently ride into any frame (owner, dashboard-user, or app-token via the general broadcast). The ws_event_scope strip remains as defense-in-depth, but the source no longer emits unlisted keys.
• Stale-session identity root cause not fixed here — accepted and deferred. This PR is scoped to the public-repo visibility gate (the independently-justified half). The is_owner_dashboard_request re-mint / stale_session_reauth identity issue is a separate change with its own security surface; it warrants a tracked follow-up rather than widening this PR. The visibility gate stands on its own merits (public-repo lifecycle is world-visible), independent of that identity fix.
• SSE carries the widened list — intended and safe: SSE runs on dashboard-user tokens (not app tokens), and the same public-only gate + allowlist projection apply, so SSE only ever carries public-repo status.

BLOCKING (concurrent forced refresh could expose newly-private status): fixed exactly as suggested. The turn-boundary path forces both the status read and the visibility read, but they run as concurrent tasks — if status finished first it could broadcast fresh (now-private) status against a still-cached-public visibility entry.

schedule_visibility_refresh(..., force=True) now synchronously invalidates a cached public flag before spawning the refresh task: the entry is dropped to unknown up front (timestamped now, so it reads as fresh-unknown not stale), so is_repo_public fails closed for the entire in-flight window. The refresh restores public only on a positive reconfirmation, and its on_update re-serializes the sidebar when it does. So during revalidation a non-owner sees no status (owner-only), closing the race.

Regression test added (test_force_synchronously_invalidates_public_before_refresh): holds the refresh open and asserts is_repo_public returns None throughout the in-flight window after a forced refresh of a previously-public repo.

Note: this run's CI was fully green (all 4 shards) before this push — the earlier failures were unrelated pre-existing flakes on files this PR doesn't touch. Local: full mypy clean, 93 tests pass, isort/flake8/black green.

BLOCKING (GitLab project visibility ≠ MR/CI visibility): correct and GitLab-specific. A GitLab project can be visibility: public yet restrict individual features — merge_requests_access_level / builds_access_level may be private (members-only) or disabled — so a credentialed refresh could surface member-only MR/CI status to a non-owner.

Fixed: the GitLab visibility read now requires the project to be public AND both merge_requests_access_level and builds_access_level to be "enabled" (available at the project's public visibility, i.e. anonymously readable) before returning True. private/disabled/missing levels fail closed (owner-only). GitHub is unaffected — a public GitHub repo's PRs and checks are anonymously public, no per-feature split.

Tests added: public + both features enabled → public; public + member-only MR → not public; public + missing feature levels → fail closed.

Local: full mypy clean, 96 tests pass, isort/flake8/black green. Rebased onto current main.

BLOCKING (GitLab private pipeline status via public_jobs=false): correct and distinct from round-5. GitLab's public_jobs ("Public pipelines") is a separate gate from builds_access_level: even a public project with builds_access_level: enabled hides pipeline/job status from non-members when public_jobs is false, so a credentialed status refresh would leak private CI state to a non-owner.

Fixed: the GitLab visibility read now additionally requires data.get("public_jobs") is True before treating CI status as anonymously public. Missing/false fails closed (owner-only). Full gate: visibility == "public" AND merge_requests_access_level == "enabled" AND builds_access_level == "enabled" AND public_jobs is True. GitHub is unaffected.

Test added: public + both feature levels enabled + public_jobs: false → not public.

BLOCKING (public->private transition can leave status visible): correct and distinct from the earlier refresh-lag/concurrency fixes. On the FORCE path, schedule_visibility_refresh synchronously pre-invalidates a cached-public entry to (now, None) before spawning _refresh_repo_visibility (the round-4 fail-closed race fix). But _refresh_repo_visibility then computed prev_public from that just-written unknown → False. If the repo genuinely went private, the fresh read is also False, so new_public != prev_public was False == False → NO on_update fired, and connected non-owners kept the previously-rendered public chip status until some unrelated push re-serialized.

Fixed: schedule_visibility_refresh now captures the TRUE rendered-public baseline BEFORE the pre-invalidation and passes it to _refresh_repo_visibility(..., prev_public_override=...), so the on_update comparison measures the flip against what non-owners actually see. A public->private (or public->unknown) transition now queues the hide-the-chip update. The non-force path is unchanged.

Test added: seed public, force-refresh a repo that now reads private → on_update is queued and is_repo_public becomes False.

Local: full mypy clean, 102 tests pass, isort/flake8/black green. CI was fully green on the prior two heads; Opus/Design/UX PASS (FP re-running).

BLOCKING (stale-fresh visibility can authorize newly-fetched private status): correct and distinct from the earlier TTL-expiry (round-1) and turn-boundary-force (round-3/4) fixes. Trigger: an ordinary (non-force) status refresh lands a freshly-fetched, now-private status while this URL's visibility entry is still WITHIN its TTL. schedule_visibility_refresh's freshness check then SKIPS the visibility read, so is_repo_public returns the stale-fresh public flag and a non-owner is served the new private status. Neither TTL expiry (fails closed) nor the force path covered this window.

Fixed: when _refresh_check_status confirms a status CHANGE, it now force-revalidates visibility for exactly that URL in lockstep — schedule_visibility_refresh([url], on_update, force=True), which bypasses the TTL and synchronously fails a cached-public entry closed for the in-flight window (restoring public only on positive reconfirmation). Bounded to real status transitions, so it adds no steady-state load.

Test added: _refresh_check_status with a changed status force-revalidates visibility for the URL.

BLOCKING #1 (GitHub internal repos pass the public gate): correct and distinct. isPrivate is False for BOTH public AND internal (Enterprise) repos, but internal is visible only to enterprise members, not anonymously — so not isPrivate would classify an internal repo public and leak credential-backed status to a non-owner. Fixed: the GitHub visibility read now requests visibility and returns public only for visibility == "public" (isPrivate kept as a belt-and-braces private check). This mirrors the GitLab "public"-only gate; internal/private → owner-only. Tests: internal → not public; private → not public; public → public.

BLOCKING #2 (full-payload writes bypass visibility revalidation): the mechanism is real — record_full_payload_status is a SECOND authoritative status writer (the detail panel) that the round-8 lockstep (added to _refresh_check_status) did not cover, so a public→private change refreshed there could serve new status against a stale-fresh public flag. Fixed at the mechanism: record_full_payload_status now force-revalidates visibility (schedule_visibility_refresh([url], force=True)) in lockstep on a confirmed status change — the same guard the chip path already has. I did NOT revert the dashboard_user attachment (the suggested fix): the leak is closed by making the second writer revalidate, so the non-owner public-repo feature — the whole point of the PR — stays intact. Test added: full-payload status change forces a force=True visibility revalidation for the URL.

BLOCKING (non-owners trigger private-repo credentialed reads — ws.py:463): correct and genuinely new — distinct from every prior round, which all concerned serving/projecting status. This is a scheduling-time side channel: the connect path scheduled schedule_check_refresh(urls, …) for a non-owner dashboard user across all change URLs, so a non-owner connection drove the operator's gh/glab credentials to read private repos (consuming provider quota / making authenticated reads on repos the connection has no right to cause traffic for) — even though the rendered status was already gated public-only downstream.

Fixed exactly as suggested — status refreshes only for owners or already-confirmed-public URLs; visibility refreshed separately for the rest:

• Visibility refresh (schedule_visibility_refresh) still runs for every URL — it is the cheap, non-owner-appropriate probe and the gate the render path already fails closed on; it is what classifies an unknown repo public (unlock) or private (owner-only).
• Status refresh (schedule_check_refresh, credentialed) now runs: for an owner → all URLs (their own repos/credentials, unchanged); for a non-owner dashboard user → ONLY URLs with is_repo_public(url) is True (cache-only, never blocks). Unknown/private URLs get the visibility probe only; once one confirms public, a later refresh cycle picks up its status.

So a non-owner can no longer initiate a credentialed status read on a private or not-yet-confirmed-public repo. The public-repo chip feature (issue #6786's ask) stays intact — a confirmed-public repo still refreshes and renders for dashboard users.

Test added (test_non_owner_status_refresh_only_for_confirmed_public): non-owner connect with one confirmed-public + one unknown/private URL → visibility probed for BOTH, status refresh scheduled for the public URL ONLY. Existing owner-only connect test updated: an unseeded (unknown-visibility) repo now asserts schedule_check_refresh is NOT called for the non-owner.

Local: full mypy clean (1210 files), 107 tests pass, isort/flake8/black green. CI was fully green on the prior head 5220103f1; Opus/Design/First-Principles/UX PASS (Design/FP advisory CONCERNS only).

GPT 5.6 — both addressed on 5b212c14c

Both findings are genuinely new mechanisms (distinct from round-10's connect-time scheduler), fixed by code — the non-owner public-repo feature stays intact.

BLOCKING 1 (ws.py:609 — SECOND non-owner status-driver path): correct — round-10 gated only the connect-time scheduler; the periodic _refresh_check_loop (started for any dashboard user via _run_status_driver = owner_request or is_dashboard_user) still called schedule_check_refresh(urls, …) for ALL urls, so a non-owner connection drove operator-credentialed status reads on private repos on every refresh round. Fixed identically: the periodic loop now schedules schedule_visibility_refresh for every url (cheap probe) but schedule_check_refresh only for owners OR urls with is_repo_public(url) is True (non-owner). Unknown/private urls get visibility only.

BLOCKING 2 (source_providers.py:6134 — visibility invalidation ordered after private status is observable): correct. In _refresh_check_status, the chip cache is written up front, then on a detected change the code ran flap-handling and await _invalidate_full_payload_cache(url) BEFORE schedule_visibility_refresh(force=True). So (a) the flap path early-returned without ever invalidating visibility, and (b) during the full-payload await a concurrent slots push could observe the newly-cached (now-private) status against a still-fresh public flag. Fixed: the schedule_visibility_refresh([url], on_update, force=True) now runs IMMEDIATELY after changed is detected — before flap handling and before the first await. force=True synchronously fails a cached-public entry closed (it pre-invalidates before spawning the task), so the private status is never observable against an un-invalidated public flag, and the flap path also invalidates before returning.

Tests: test_non_owner_status_refresh_only_for_confirmed_public (round-10) still holds; periodic-loop test updated to seed the repo public (non-owner status refresh allowed only for confirmed-public); NEW test_status_change_forces_visibility_before_flap_and_await asserts visibility force-invalidation precedes both the flap early-return and the full-payload await.

GPT 5.6 + Opus 4.8 — all addressed on 7f0fda84e

All findings are genuine and fixed by code; the non-owner public-repo feature (issue #6786's ask) stays intact.

BLOCKING (GPT + Opus, same root — two more un-gated non-owner status-read sites): correct. Rounds 10/11 gated ws.py (connect + periodic), but the SAME scheduling-time credentialed-read side channel still existed on two paths widened to non-owners in this diff:

• chat_handlers.py GET /api/chat/slots: now mirrors the WS gate — schedule_visibility_refresh for every url; schedule_check_refresh only for owners OR [u for u in urls if is_repo_public(u) is True] (non-owner).
• state.py refresh_slot_source_status (turn-completion): visibility force-revalidated for all urls; the TTL-bypassing request_check_refresh_now now runs for every url only when an OWNER window is open, else restricted to confirmed-public urls (a non-owner-only audience never drives a gh/glab read on a private/unknown repo).

BLOCKING (GPT — public-status grant not SEL-audited, state.py:2240): fixed WITHOUT reverting the feature. The non-owner public-status grant in _project_source_links._attach now emits an SEL log_api_access(operation="source_link_public_status", outcome="allowed", resources=<url>) — deduplicated per url per 300s window (mirrors ws_event_scope._audit_decision), because this runs per-link on every push broadcast and an un-deduplicated write would be unbounded on the hot path. The authorization decision is now auditable (AUTOSDE backend-security-controls: grants included), and the feature is preserved.

BLOCKING (GPT — test leaves a debounce handle on the closed loop, test_public_repo_chip_status.py): fixed. The autouse fixture now, after yield, cancels + resets the global _check_update_handle and clears _check_update_callbacks (and the new grant-audit dedup dict), so a test that armed the debounced update cannot leak a TimerHandle across tests (no-test-side-effects).

Tests: test_non_owner_public_status_grant_is_sel_audited (grant emits one allow event, deduped, owner path silent); existing WS gate tests still hold.

GPT 5.6 round-13 — respectfully declining this one (design disagreement)

This finding asks to "gate visibility refreshes on owner status across HTTP, WebSocket, and turn-boundary paths." I'm not applying it, because — unlike rounds 10–12, which were genuine status-read leaks I fixed — this prescription removes the feature this PR exists to add (issue #6786), and its premise does not hold up:

1. The visibility probe is the feature's foundation, not a leak. To show a non-owner a PUBLIC-repo chip, the system must first learn the repo is public. That determination IS _fetch_repo_visibility: gh repo view <repo> --json isPrivate,visibility (GitHub) / glab api projects/{id} (GitLab). Gating it on owner-only means is_repo_public(url) can never become True for any non-owner-driven refresh, so every non-owner chip stays bare forever — i.e. the PR is reduced to a no-op. All four status-read sites are already gated on is_repo_public(url) is True (rounds 10–12); that gate is only ever satisfiable because the visibility probe is allowed to run.

2. It reads visibility METADATA only — no private content. The call requests exactly isPrivate,visibility (GitHub) and the project record's visibility + feature-access levels (GitLab). On a private repo it returns isPrivate: true / visibility != "public" and the code fails closed (return False). It never reads PR bodies, CI logs, or any member-only content — it reads the single flag whose entire purpose is to PREVENT the status leak. Calling that "an unauthorized private-repository read" conflates a public/private classification probe with reading private data.

3. The quota/abuse concern is already bounded. schedule_visibility_refresh is TTL-gated, _visibility_inflight-deduped (one in-flight fetch per repo), and runs under _check_semaphore (concurrency cap). A non-owner connection cannot fan unbounded credentialed probes — multiple dashboard users collapse to one fetch per repo per TTL.

If the maintainers' security posture is that a non-owner must never cause ANY operator-credentialed provider call — even a bounded visibility-flag read — then the correct resolution is to close #6786 as won't-fix, not to merge a feature gutted to a no-op. I've surfaced this to the repo owner for a decision rather than churn. Opus 4.8 passed with no blocking findings on this same head; Design / First-Principles are advisory CONCERNS; UX skipped (no UI surface); CI is fully green.

GPT 5.6 round-13 — resolved by code on b5ff36524

Adopting the fix as requested: visibility refreshes (and status refreshes) are now gated on owner status across all paths — WebSocket connect, the periodic driver, GET /api/chat/slots, and the turn-boundary refresh. A non-owner connection now triggers NEITHER a schedule_check_refresh NOR a schedule_visibility_refresh, so no non-owner-driven gh/glab provider read occurs anywhere.

The public-repo chip feature (issue #6786) is preserved without any non-owner credentialed call, via an owner-populates / non-owner-reads split:

• The owner's connection and periodic driver refresh both caches (_check_cache + _visibility_cache) for every repo its slots reference — the owner is the dashboard operator, running under its own credentials, which is legitimate.
• A non-owner dashboard connection renders those caches read-only at serialization time via the existing fail-closed is_repo_public gate in _project_source_links (dashboard_user and _repo_is_public(url) is True). It spawns no driver and schedules no provider work.
• A repo the owner has never classified stays owner-only for non-owners (fail closed). With no owner window ever open, non-owners see bare chips — the correct fail-closed posture.

Net effect: non-owner authenticated dashboard viewers still get merged/closed/open/draft + CI glyphs for public repos (the owner's driver having classified them), and the scheduling-time credentialed-read side channel is closed completely — visibility included.

Changes: ws.py (connect + _refresh_check_loop + _run_status_driver now owner-only), chat_handlers.py (api_chat_slots refreshes only when include_check_status/owner), state.py (refresh_slot_source_status returns early unless an owner window is open). Tests updated to the owner-only contract (non-owner connect / periodic / turn-boundary all assert zero provider work); the SEL-audited non-owner public-status GRANT at render time is unchanged.

Local: full mypy clean (1210 files), 110 tests pass, isort/flake8/black green, single commit, 7 files. CI was fully green on the prior head fc51fdce4; Opus/UX pass, Design/First-Principles advisory.

GPT 5.6 round-14 — addressed on 7720f152f

BLOCKING (source_providers.py — inflight refresh bypasses forced fail-closed invalidation): correct and genuinely new — fixed by code (took your non-revert alternative: "ensure force invalidates before this return and stale inflight results cannot restore public"). Two mechanism changes:

1. The force=True synchronous pre-invalidation (drop cached-public → (now, None)) now runs before the if key in _visibility_inflight: continue dedup return. Previously a forced refresh arriving while a (pre-flip) refresh was already in flight would continue without invalidating, leaving the stale-public entry live. Now is_repo_public fails closed for the in-flight window regardless of ordering.
2. Added a per-key force-generation counter (_visibility_force_gen): the force path bumps it on each public→private pre-invalidation; _refresh_repo_visibility snapshots it at start and, if it changed while fetching, REFUSES to write a positive public result (records unknown instead). So an in-flight positive read whose fetch predates the flip can never restore public across a force-invalidation — the leak you identified is closed at the root.

Tests added: test_force_invalidates_public_even_when_refresh_already_inflight (force fails closed despite in-flight dedup + bumps generation) and test_stale_inflight_positive_cannot_restore_public_across_force (a positive read completing after a mid-flight force-invalidation does NOT restore public).

FINDING (ws.py — _run_status_driver = owner_request leaves cold non-owner-only sessions unable to populate public status): this is the intended, documented fail-closed behavior of the owner-populates/non-owner-reads model this round adopted at your request — not a defect. The owner is the dashboard operator and is effectively always connected; its driver classifies visibility and fetches status, and non-owner viewers render those caches read-only. With NO owner ever connected, non-owners see bare chips, which is the correct fail-closed posture (no non-owner-driven credentialed provider read anywhere — the property this review chain has been protecting). I'm not reverting the non-owner READ path: that is the entire feature (issue #6786). If the maintainers' position is that the feature must not exist unless a non-owner-safe cache producer exists, that's a close-as-wontfix product decision for the repo owner, not a code change I can make without deleting the requested feature.

Local: full mypy clean (1210 files), 112 tests pass, isort/flake8/black green, single commit, 7 files. CI was fully green on the prior head b5ff36524; Opus/UX/Design/First-Principles non-blocking.

GPT 5.6 round-15 — addressed on ebda39d67

BLOCKING (source_providers.py — forced refresh can accept stale public when the entry is already unknown): correct refinement of the round-14 fix — fixed by code (your suggested fix). The force-generation bump now fires on every forced refresh, BEFORE the inflight-dedup return, regardless of the current cache value (previously it was gated on entry[1] is True, so a second force arriving while the entry was already unknown — first force landed, pre-privacy fetch still in flight — skipped the bump and let that in-flight positive read restore public). The cache is still only clobbered-to-unknown when currently public (an already-unknown entry is already fail-closed), but the generation always advances, so any in-flight read that predates the force is refused write-back. Test added: test_force_bumps_generation_even_when_entry_already_unknown.

BLOCKING (state.py — private-repository denials not audited): fixed. Added _audit_public_status_denied symmetric to the grant audit — when a non-owner dashboard user is denied status on a non-public (private/unknown/stale) change link, _project_source_links._attach now emits an SEL outcome="denied" event, deduplicated per url per window (same hot per-link path). AUTOSDE now sees BOTH the allow and the deny decisions. Owner and app-token paths do not reach this branch. Test extended: the SEL-audit test now asserts the deny event fires and dedups.

FINDING (state.py — stale docstring contradicts the owner-only return): the behavior is intended (owner-populates / non-owner-reads, the model adopted at your round-13 request), so I did not revert — but you're right the docstring still said "or a non-owner dashboard-user window", which is now wrong. Corrected it to state the turn-boundary refresh fires ONLY when an owner window is open. Not a code/behavior change.

Local: full mypy clean (1210 files), 113 tests pass, isort/flake8/black green, single commit, 7 files. CI was fully green on the prior head 7720f152f; Opus PASS (no blocking), UX pass, Design/First-Principles advisory CONCERNS.
