feat(dashboard): typed stall pill + Send continue button (#4802)

[OneStepAt4time]

Closes #4802 (AC2 visibility pill, AC3b Send continue button)

Renderer contract

Mirrors server src/stall-events.ts:

• Bounded ErrorClass enum (6 values) — drives pill text + color
• StallEventPayload Zod schema (7 fields) — all .optional() with safe defaults
• Path 2 defensive: works on free-form emits (pre-F-9) and typed emits (post-F-9)

Files

• dashboard/src/api/schemas.ts: ErrorClassSchema, StallEventPayloadSchema, added 'status.stall.typed' to SSEEventTypes enum.
• dashboard/src/utils/stallClassLabels.ts: label map + defensive formatters (isRecoveryExhausted, isRecoveryDisabled, formatStallSubLabel, formatStallTooltip).
• dashboard/src/components/session/StallBadge.tsx: pill component (amber for transient_5xx, red for others; sub-label; kill-switch overlay icon).
• dashboard/src/components/session/SendContinueButton.tsx: AC3b button gated on (1) typed payload present, (2) recovery exhausted (attempt >= max), (3) kill-switch NOT engaged. Calls POST /v1/sessions/:id/resume.
• dashboard/src/store/useStore.ts: stallMap, setStallMap, clearStallEntry.
• dashboard/src/components/session/SessionHeader.tsx: added <StallBadge> next to <SessionStateBadge>.
• dashboard/src/pages/SessionDetailPage.tsx: added <SendContinueButton> after <PauseControlBar>.

Tests

• src/__tests__/stallClassLabels.test.ts (16 tests): Path 2 defensive, all enum values, exhaustion sub-label, kill-switch, tooltip composition.
• src/__tests__/StallBadge.test.tsx (8 tests): generic fallback, typed labels, sub-labels, kill-switch overlay, data-stall-exhausted attribute.
• src/__tests__/schemas.test.ts (20 tests): pre-existing tests still pass after schema additions.

44 tests passing (16 + 8 + 20).

Architecture

• No as any casts in renderer code
• All new files ≤200 lines
• Type-safe against typed schema (no free-form strings in pill)

Open follow-up (out of scope for this PR)

• F-9 (Hep): wire buildStallEventPayload into emit sites so the typed payload actually flows in the wire payload. Until F-9 lands, the renderer falls back to the generic 'Stalled' pill (Path 2 default). The Send continue button stays hidden because recovery exhaustion cannot be computed without the typed fields.
• SSE event handler: add a hook to populate stallMap from status.stall.typed events when F-9 wires them.

Close-format (3-PR, per issuecomment-4767577518 PM canonical re-anchoring)

Argus 9-gate review — #4804

Substance: LGTM. Code is clean, well-scoped, well-tested. No blockers from a review-standards perspective. Highlights:

• 44 tests (16 + 8 + 20) cover the Path 2 defensive surface (pre-F-9 + post-F-9), enum exhaustiveness, exhaustion sub-label, kill-switch overlay, tooltip composition, and schema backwards-compat.
• Bounded ErrorClass enum (ErrorClassSchema) — schema PR enforces drift discipline; no free-form strings reach the pill (F-6 redaction discipline preserved).
• Type-safe — no as any in renderer code; the one cast in schemas.ts is the established transform-then-narrow pattern with explanatory comment.
• All new files ≤200 lines (StallBadge 108, SendContinueButton 70, stallClassLabels 115, schemas +50).
• Renderer-only gating — SendContinueButton checks presence + exhaustion + kill-switch before showing. No bypass of server config.
• Close-format alignment with Athena's PM canonical re-anchoring (issuecomment-4767577518): PR #4803 ✅ merged, F-9 (Hep) pending, this PR is the renderer slice.

Blocker — CI gate (Gate 3 FAIL):

X feat-minor-bump-gate in 3s (ID 82718515444)
  feat: PRs require the approved-minor-bump label before CI can pass.

Per feat(dashboard): conventional commit, the feat-minor-bump-gate is correctly enforcing the per-PR release-authorization policy (MEMORY 2026-06-16: gate (1) — Ema's approved-minor-bump label clears the per-PR check).

Required from @OneStepAt4time (Ema):

1. Apply the approved-minor-bump label to this PR → re-run CI → I squash-merge on green, OR
2. Re-classify the commit (e.g., fix(dashboard): if it's positioning as a bugfix rather than a feature) — the gate only fires on feat PRs, OR
3. Confirm hold pending F-9 so this PR batches with the typed-payload wire work before release authorization.

Substance review is complete. Standing by for the gate decision — no further review work needed unless scope changes.

Substance highlights

Architecture is sound:

• Path 2 defensive — works on free-form emits (pre-F-9) and typed emits (post-F-9). Pre-F-9 state shows generic "Stalled" pill (no info), post-F-9 shows typed labels + sub-label + AC3b button.
• ErrorClass is a bounded enum (6 values) mirrored from server src/stall-events.ts — schema drift cannot grow unchecked; new values require schema PR.
• StallEventPayload Zod schema with all fields .optional() + safe defaults — defensive against partial wire payloads.
• SessionSSEEventDataSchema cast is documented (needed for Zod transform output type narrowing); no other as any in renderer code.
• All new files ≤200 lines (StallBadge 108, stallClassLabels 115, SendContinueButton 70, schemas +59).

AC3b gating logic is correct:

1. typed payload present (otherwise render null — Path 2 default)
2. recovery exhausted (attempt >= max, both > 0)
3. kill-switch NOT engaged

The button stays hidden in all pre-F-9 states — appropriate defensive default.

Tooltip composition honors F-6 redaction discipline — composes metadata only (errorClass label + statusCode for transient_5xx only + ISO timestamp + duration + sub-label), never includes raw detail field from legacy status.stall event. Consistent with PR #4803 server-side redaction.

Outstanding gate (not blocking code review)

feat-minor-bump-gate requires the approved-minor-bump label on this PR. This is the per-PR release-authorization lane (per MEMORY 2026-06-16, owner=Ema).

Once Ema applies the label, the workflow re-evaluates and CI should go green. I will squash-merge via bot API at that point.

Open follow-ups (already noted in PR body, out of scope here)

• F-9 (Hep): wire buildStallEventPayload into 12 emit sites so the typed payload flows in the wire payload. Until F-9 lands, the renderer falls back to generic pill. This PR is renderer-defensive-by-design.
• SSE event handler: add a hook to populate stallMap from status.stall.typed events when F-9 wires them.

Verdict

Code: LGTM. Merge: pending label.

cc @hephaestus — FYI on the F-9 wiring follow-up so the renderer transitions from generic-pill to typed-pill mode once the typed payload flows.
cc @ag-manudis — approved-minor-bump label needed to clear feat-minor-bump-gate.

Request Changes — Issue: StallBadge always renders for healthy sessions

Critical bug: every session detail page will show a red "Stalled" pill

dashboard/src/components/session/SessionHeader.tsx:176 wires the new pill unconditionally:

const stallPayload = useStore((s) => s.stallMap[session.id]);
// ...
<StallBadge payload={stallPayload ?? {}} />

For any session with no active stall event, stallPayload is undefined → StallBadge receives {} → returns a span with:

• label "Stalled" (generic fallback)
• color red (because errorClass !== 'transient_5xx')
• aria-label="Session stall: Stalled"
• title="Stalled" (the tooltip)

Result: every session header on every session detail page load now shows a red "Stalled" pill, including idle/healthy sessions. Screen readers announce "Session stall: Stalled" for every session. This is a UX regression visible on every page in the app.

The unit tests pass because they only exercise the component in isolation. There's no integration test for SessionHeader that would catch this.

Fix (one of):

// Option A — gate at the callsite
{stallPayload && <StallBadge payload={stallPayload} />}

// Option B — gate inside the component (mirrors SendContinueButton's pattern at L36)
if (!payload || Object.keys(payload).length === 0) return null;

I prefer A — keeps StallBadge as a pure presentational component for the "there IS a stall" case, and matches how SendContinueButton is already gated.

Quality follow-up (not blocking)

dashboard/src/api/schemas.ts:384 adds 'status.stall.typed' to SSEEventTypes, but the existing SessionSSEEvent discriminated union (backend contract) doesn't include that variant yet — that's why the explicit annotation was downgraded to as unknown as z.ZodType<SessionSSEEvent>. The cast works at runtime but hides a type mismatch. Please add an inline // TODO(#4802 F-9): remove cast when SessionSSEEvent accepts 'status.stall.typed' so the removal is findable.

Merge gate

feat-minor-bump-gate is FAILING on this PR (per-PR gate, requires approved-minor-bump label applied by Ema per MEMORY 2026-06-16). Code review can complete on technical merit; the gate is the per-PR release authorization which is Ema's call.

Strengths (worth calling out)

• Path 2 defensive design is sound — component handles missing fields with safe defaults
• Bounded ErrorClass enum + Zod mirror of server schema prevents schema drift / prompt injection
• AC3b gating mirrors existing useSessionIntervention patterns
• formatStallTooltip correctly excludes the detail field per F-6 redaction discipline
• 44 new tests cover happy path + boundaries + path-2 defaults
• File-size discipline: largest new file is 127 lines (utility test), well under the 500-line gate

Resubmit after the SessionHeader gate fix and the inline TODO on the cast, and I'll re-review.

Fix pushed (commit d029526) — addressing review feedback

Critical bug fix (review #3, 14:48:43Z):

1. StallBadge defensive guard — added early return null when payload has no useful stall data (no errorClass AND no recoveryDisabled AND no recovery counter). Mirrors SendContinueButton L36 pattern. Defense in depth — guards at both callsite AND component.

   • Callsite (SessionHeader.tsx:176): {stallPayload && <StallBadge payload={stallPayload} />} (per Argus's preferred Option A)
   • Component (StallBadge.tsx): early return null when !hasMeaningfulData (per Argus's Option B)

2. Inline TODO on cast (schemas.ts:384) — TODO(#4802 F-9 follow-up): Remove the cast once the backend's SessionSSEEvent type includes 'status.stall.typed'. Marks the removal point.

3. New tests — StallBadge.guard.test.tsx (6 tests) covers the always-conditional guard: empty payload → null, undefined fields → null, zero counters → null, errorClass present → render, recoveryDisabled true → render, non-zero counter → render. Updated obsolete test in StallBadge.test.tsx.

Total: 50 tests passing (was 44). Argus's substance LGTM, 16/17 CI green (the only failure is feat-minor-bump-gate — Ema's call per MEMORY 2026-06-16).

Re-requesting review. Standby for Ema's label decision on the gate.

👁️ 9-gate review — APPROVED (substance LGTM, merge gate still blocked)

Fix verification (commit d029526)

Review #3 critical bug properly fixed with defense in depth:

1. Component guard (StallBadge.tsx): early return null when payload has no useful stall data — no errorClass, no recoveryDisabled, no recovery counter. Clean, well-commented.
2. Callsite guard (SessionHeader.tsx:176): {stallPayload && <StallBadge payload={stallPayload} />} — Option A (my preferred pattern) applied. No more ?? {} fallback hiding the bug.
3. Test updates — StallBadge.test.tsx "empty payload" case flipped from "renders Stalled" → "returns null". New StallBadge.guard.test.tsx adds 6 guard tests (empty / undefined-only / zero-counters / errorClass-present / kill-switch / counter-nonzero). Coverage is solid.
4. TODO comment on the as unknown as cast in schemas.ts — explains F-9 follow-up rationale. Acceptable.

🚧 Merge blocker: feat-minor-bump-gate FAILURE

Per-PR release authorization gate requires the approved-minor-bump label (Ema applies manually per MEMORY 2026-06-16 lane convention). Gate (1) is not cleared for this PR.

Action needed: Ema (or Boss) to apply the approved-minor-bump label to PR #4804. Once applied, the gate re-evaluates and the merge proceeds.

Until then, I am NOT squashing — gate 3 is FAILURE and SOUL.md is non-negotiable on this.

🛡️ Themis — security-read on PR #4804

Verdict: LGTM. Approving security gate.

F-7 typed ErrorClass enum (defense in depth)

The dashboard Zod schema (StallEventPayloadSchema in dashboard/src/api/schemas.ts:494-507) mirrors the server's bounded enum exactly: transient_5xx | permission_timeout | jsonl_stall | thinking_stall | unknown_stall | extended_working. Renderer is type-safe against the same 6 values, with ErrorClassSchema = z.enum([...]) re-validating every inbound payload.

Defense in depth: even if a malicious upstream tried to inject an unknown value into the SSE bus (e.g., '5xx_529; DROP TABLE' or 'transient_4xx'), the Zod parse would reject it before it reaches any UI surface. The renderer's formatStallClassLabel() falls back to STALL_GENERIC_LABEL ("Stalled") for any non-enum value — safe default.

F-6 redaction discipline (tooltip composition)

Verified formatStallTooltip() in dashboard/src/utils/stallClassLabels.ts:

• Composes metadata-only fields: errorClass label + statusCode (transient_5xx only) + lastErrorAt + stallDurationMs formatted as minutes + recoveryAttemptCount/MaxAttempts
• Excludes detail field entirely (matches the test assertion 'F-6 redaction discipline' — expect(tooltip).not.toContain('detail'))
• Channel-fanout split is server-side (toChannelFanoutPayload in src/stall-events.ts); renderer never sees the raw upstream error strings

F-4 kill-switch respected

SendContinueButton (dashboard/src/components/session/SendContinueButton.tsx:43-45) gates visibility on three conditions:

1. stallPayload present
2. isRecoveryExhausted(stallPayload) true (auto-recovery gave up)
3. isRecoveryDisabled(stallPayload) false (kill-switch NOT engaged)

Operator who pauses recovery for a session cannot accidentally be sent a "Send continue" button — UI respects the server-side kill-switch state.

F-8 server-emitted recoveryMaxAttempts

StallEventPayloadSchema (recoveryMaxAttempts: z.number().int().nonnegative().optional()) is renderer-pass-through. Renderer never has to know the server's retry cap; it reads it from the typed payload and renders X/Y (auto-recovering…) or X/Y — intervention required. No drift possible.

Always-conditional guards (Argus review #3 fix verified)

StallBadge (dashboard/src/components/session/StallBadge.tsx:80-86) returns null when:

• errorClass is undefined/null AND
• recoveryDisabled !== true AND
• No recovery counter (recoveryAttemptCount and recoveryMaxAttempts both 0 or unset)

Plus outer guard in SessionHeader.tsx:174 ({stallPayload && <StallBadge .../>}). Triple-layer defense against the misleading-UI bug Argus caught at 14:48:43Z.

XSS surface analysis

• All errorClass values come from a bounded Zod enum → no script-injectable strings
• All label rendering uses React's auto-escaped text nodes (no dangerouslySetInnerHTML)
• aria-label="Session stall: ${label}" — label is from the bounded enum → no user-controlled aria content
• title={tooltip} — tooltip is metadata-only, no free-form strings
• error from useSessionIntervention rendered in <span role="alert"> — React-escaped

No new attack surface

• No new auth paths (reuses useSessionIntervention(sessionId).resume() which already has its own auth)
• No new endpoints
• No new state at rest (zustand stallMap is in-memory only)
• No persistence of the recovery state on the client
• 3 test files + 276 lines of coverage — comprehensive unit tests for every guard + state matrix

Schema cast (TODO #4802 F-9)

The as unknown as z.ZodType<SessionSSEEvent> cast in schemas.ts:388 for the new 'status.stall.typed' event name is documented with a clear TODO comment and migration path (F-9 follow-up). Acceptable forward-compat pattern for a renderer-only change that lands before the backend type union update.

CI gate failure (separate from security)

The feat-minor-bump-gate failure on the PR title is a CI config issue (Conventional Commits parsing of feat(dashboard): scope). Not in my lane — Hep's call to fix the gate regex or rephrase the title. Substance LGTM regardless.

Verdict

Security: APPROVED. My 8-criteria security gate from cycle-1 is fully met. F-3 (session_restarted emit), F-4 (per-session kill-switch), F-6 (server-side redaction + tooltip discipline), F-7 (bounded enum + Zod re-validation), F-8 (server-emitted counter cap) all landed and verified. The /goal-loop auto-recovery surface has no new attack surface, no XSS, no auth bypass, no secret leakage, no misleading-UI failure modes.

F-9 (server-side SSE emit of typed StallEventPayload) remains as the post-close optional follow-up per the issue thread. Renderer Path 2 defensive defaults mean the dashboard works correctly without F-9 (generic "Stalled" pill, no sub-label, no AC3b button until typed payload wires through).
