A high-tier native review runs four reviewer lenses through the Pi host relay, and each lens run is an in-process model completion taking several minutes (runInProcessReviewer, lib/inprocess-reviewer.ts). While capture runs, the session shows only a static amber in-flight card naming the lens because:
gentle_review_capture and gentle_review_capture_group discarded the streaming onUpdate callback in their execute handlers (extensions/gentle-ai.ts).
Per-slot progress was computed only after all slots settled and returned as the tool's final result value (reviewHostRelayGroupProgress).
This left single-lens and multi-lens reviews looking hung for minutes with zero feedback into prompt materialization, in-flight review completions, or group concurrency.
Solution
Thread Progress Callbacks through the Relay: In lib/review-host-relay.ts, added ReviewHostRelayProgressCallback and ReviewHostRelaySlotProgress tracking slot phases (materializing, reviewing, prepared, submitting, submitted). Threaded an optional progress callback through prepareReviewHostRelaySlot, submitReviewHostRelayPreparedResult, runReviewHostRelaySlot, and runReviewHostRelayReviewerGroup.
Compact Progress Formatters: Added formatReviewHostRelaySlotProgress and formatReviewHostRelayGroupProgress to format compact, human-readable status lines for single slots and parallel groups.
Wire onUpdate in Capture Operations: In extensions/gentle-ai.ts, wired onUpdate in gentle_review_capture and gentle_review_capture_group through executeReviewCaptureOperation and executeReviewCaptureGroupOperation, updating live progress across parallel reviewer runs and provider submissions.
Testing
node --experimental-strip-types --test tests/review-host-relay.test.ts (45/45 passed, including progress callback tests for single and group runs)
node --experimental-strip-types --test tests/review-relay-transport-agent.test.ts (16/16 passed, including live onUpdate verification for capture and group capture)
Review relay operations now report progress phases for individual reviewer slots. Single and grouped capture operations forward these updates through their onUpdate callbacks. Tests cover relay phase order and capture-level progress updates.
The relay adds progress phases, payloads, callbacks, and formatting helpers. It reports preparation and submission phases, and forwards indexed preparation progress for reviewer groups. Tests check phase order and slot indices.
Capture callback wiring and slot updates extensions/gentle-ai.ts, tests/review-relay-transport-agent.test.ts, odd/tasks/feat-1492-review-capture-live-progress.md
Single and grouped capture operations pass progress callbacks to the relay. Capture tools pass their onUpdate callbacks into those operations. Grouped capture tracks and emits per-slot progress through submission. Tests check single and grouped capture updates. The task document records the progress phases, callback wiring, and verification tasks.
A progress-display error can make a completed capture appear to fail, even after submission. Guard the remaining progress callbacks before merging.
Security Architecture Review
Security architecture risk:🔵 Low · up to a2c55
Live progress adds visibility without changing who can run reviewers or submit results. The remaining risk is that progress can be misleading when a run fails; no new security exposure was established.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The new observable surface is the active capture tool's progress stream. The examined updates contain routing labels, phase, and elapsed time, not materialized prompts or reviewer results.
Trust Boundaries and Controls
observed — Caller-supplied capture parameters are checked against selected provider bindings before progress begins; grouped capture checks fresh status again before each submission and reconciles uncertain submission outcomes.
Resilience and Maintainability Implications
observed — Grouped updates pass the same mutable slot-state array as structured details on each emission. Whether the receiving host copies or retains those details is unverified; rendered progress text is formed at emission time.
Hardening Proposals
proposed — Consider emitting point-in-time structured snapshots and a terminal progress state aligned with the authoritative failure or reconciliation result, so retained updates cannot imply an operation is still in flight.

Docstring Coverage
Docstring coverage is inconclusive: files from earlier reviews still need to be rechecked within the check's analysis limits. Not blocking.
Full details: Linked Issues check
Explanation
Directly linked issue [#1492] is the only active target. Its coding requirements are: (a) forward the capture tools' onUpdate through the relay; (b) emit per-slot phases selected, materialized, reviewing, prepared, submitted with elapsed time; (c) show live state in the in-flight card; (d) stay read-only with no cancel affordance.
Relay requirements (verified in the lib/review-host-relay.ts diff, base to head): ReviewRelaySlotPhase includes selected, materializing, reviewing, prepared, submitting, and submitted. prepareReviewHostRelaySlot emits materializing, then reviewing with elapsedMs: 0, then prepared with elapsed time. A 1000 ms interval emits reviewing with elapsed time while the reviewer runs. runReviewHostRelayReviewerGroup forwards progress with each slot index. submitReviewHostRelayPreparedResult emits submitting and submitted. runReviewHostRelaySlot forwards the callback through both steps. The periodic callback is wrapped in try/catch and the interval is cleared in finally. No cancel path is added.
Capture-tool wiring (onUpdate in gentle_review_capture and gentle_review_capture_group) could not be read directly. The extensions/gentle-ai.ts diff was unavailable. This wiring rests on the PR summary and the described live-onUpdate tests in tests/review-relay-transport-agent.test.ts. Those sources are consistent with the requirement.
Minor deviations, not treated as unmet: the code uses materializing and has no separate materialized event. The issue names materialized. The selected phase is typed and formatted, but its emission is in gentle-ai.ts, which was not read. Rendering in the existing lifecycle card is not shown in the PR summary. It is inferred from the standard streaming update path.
Previous PASS remains supported. Changes since the previous review add the periodic-callback guard, the finally cleanup, and the unref call. These are verified in the relay diff and match the commit message.
Full details: Out of Scope Changes check
Explanation
Changes map to [#1492]. In lib/review-host-relay.ts, the progress types, formatters, optional callback parameters, reviewer-interval reporting, and group index forwarding implement live per-slot progress. The interval guard and finally cleanup protect the reviewer run from callback failures. The PR summary describes extensions/gentle-ai.ts changes as onUpdate forwarding and progress formatting only. The summary also describes tests in tests/review-host-relay.test.ts and tests/review-relay-transport-agent.test.ts for phase order, group indexes, and live capture updates. The task document odd/tasks/feat-1492-review-capture-live-progress.md supports the same work. No cancellation, provider-contract, agent-overlay, or cross-turn status change appears in the relay diff or the summary.
Limit: the extensions/gentle-ai.ts diff was unavailable, so its hunks were checked only against the PR summary. Submission-side progress formatting in the relay is not called from any non-test path in the verified diff. Its use depends on the gentle-ai.ts wiring. This does not show an unrelated change.

If onProgress throws during an interval tick, the exception escapes the reviewer promise and can terminate the Node process. This differs from errors during the initial progress call, which reject the preparation call. Catch interval callback errors and settle the preparation call through its normal error path. Clear the interval when that happens.

Handle exceptions from the periodic onProgress callback.
The setInterval callback calls onProgress without a guard. If onProgress throws, the exception happens in a timer callback. It does not reject the awaited runReviewer promise. Node raises an uncaughtException and can terminate the process while a reviewer run is active.
The initial onProgress calls run inside the async function. Their errors reject the promise. The interval path does not have this protection.
A progress callback must not break a reviewer run. Wrap the interval call in try/catch and ignore the error. A hook error can then not change the run outcome. This also matches the existing guarded unref() call.
Proposed fix
progressInterval = setInterval(() => {
- onProgress({- phase: "reviewing",- lens,- role: preparedRequest.routingKey,- elapsedMs: Date.now() - startedAt,- });+ try {+ onProgress({+ phase: "reviewing",+ lens,+ role: preparedRequest.routingKey,+ elapsedMs: Date.now() - startedAt,+ });+ } catch {+ // Progress reporting is best-effort and must not affect the reviewer run.+ }
}, 1000);

Wrap the periodic onProgress call in the setInterval callback in try/catch and
ignore callback errors so they cannot escape the timer or affect the reviewer
run. Leave the existing progress payload and interval behavior unchanged.
The test only checks that the first reviewing event has elapsedMs of 0. The reviewer resolves at once, so the 1-second interval never fires. The test title says "periodic updates", but it does not check them. A broken interval would still pass.
Hold runReviewer with a deferred promise. Wait for an event with elapsedMs > 0. Then resolve the promise. Alternatively, rename the test to match what it checks.

Add failure-path coverage for relay progress.
The new tests cover successful progress only. Add focused tests for preparation refusal or throw after reviewing progress starts, and for submission refusal after submitting progress. Assert that no later success phase is emitted and that reviewing updates stop after failure.
This is additional regression coverage. The general lib/**/*.ts test requirement is already satisfied by the added progress tests.

Keep progress errors from discarding completed reviews.
If the host callback keeps throwing after a timer update, this unguarded prepared update rejects the completed review. A throwing submitted update can also report failure after the provider accepted the result. (raw.githubusercontent.com)
Use the same best-effort handling for all phase updates. Test a callback that continues to throw after a timer tick.

Apply the existing best-effort error handling for the timer update to every
onProgress phase update, including prepared and submitted, so callback
exceptions cannot reject a completed review or report failure after provider
acceptance; add a test where the callback continues throwing after a timer tick.
