Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to This change enables feedback composition and makes the runner workspace configurable, but the current test harness can delete the entire directory supplied through PI_RUNNER_CWD, potentially removing shared developer or CI files.

Expose an immutable channel set.
EnumSet.of(...) returns a mutable set. Because ISSUE_REVIEW_CHANNELS is public static state, any caller can add IN_CONTEXT or remove IN_APP; later issue reviews will stage the wrong channel contract. Wrap the value with Set.copyOf(...) before exposing it.

A review recorded what it found and then stopped. The step that turns those findings into something a developer reads is gated on a request file the server stages, and nothing staged it: the helper that writes it had no production caller, only tests. So every review ended with observations persisted, no feedback composed, and delivery refused for want of a composition it never asked for. Both handlers now stage it. IssueReviewHandler already carried the constant for what an issue may compose — every lane, but artifact placement only, since an issue has no diff — and its test already spelled out the call; wiring it was a matter of making the code do what its own tests described. The staging helper already declines a backfill sweep. The test that would have caught this asserts over what preparation actually produces rather than calling the helper directly, because a test that calls it directly passes whether or not a review ever does. pi-runner.ts gains PI_RUNNER_CWD, the seam pi-mentor-runner.ts already has, so the runner can be driven from a harness with no /workspace. SandboxLayoutSyncTest now pins the workspace root and the task filename separately rather than their concatenation, so a derived path stays checkable without production code carrying a literal it does not use. Also repairs the live harness, which could not run: a practice fixture kept its pre-rename filename, and inputs/manifest.json — which the runner refuses to start without — was never staged.

Restrict PI_RUNNER_CWD to a test-owned directory.
If the parent process sets PI_RUNNER_CWD to an existing shared or incorrect directory, cleanWorkspace() deletes that entire directory at Lines 141-144 before the test runs. The code does not validate ownership or scope. Use a dedicated temporary or target directory, or reject values outside an allowed test root before calling deleteTree.

Description
A practice review measures a pull request, records what it found, and then a second turn composes
that into something the developer reads. The second turn is gated on the server staging
inputs/feedback-composition.json— and nothing staged it.FeedbackCompositionInputs.stage(...)had zero production callers. Three tests called it; noreview did. Both handlers imported it, and
PullRequestReviewHandlernamed it only in a commentdescribing a call that was never written.
git log -Sfinds no history of it, so this was neverwired rather than removed.
Everything downstream followed from that:
stage()uncalledexistsSync(...)inpi-runner.tsfeedbackkey[exitCode, timedOut, rawOutput, runnerDebug]requireMatchingCompositionDigest— nothing composed to matchfeedbacktable emptyBoth handlers now stage it.
IssueReviewHandleralready carried the constant describing what anissue may compose — every lane, but artifact-level placement only, because an issue has no diff — and
IssueReviewHandlerTestalready spelled out the exact call. Wiring it was a matter of making the codedo what its own tests had been describing. The helper already declines a backfill sweep.
How to test
stagesTheRequestThatTurnsFeedbackCompositionOnasserts over the file mapprepareInputsactuallyproduces, and fails when the call is removed — verified by deleting it and watching it go red.
That is the whole point: three existing tests call
stage()directly and pass whether or not a reviewever does.

Notes for reviewers
PI_RUNNER_CWD.pi-runner.tshardcodedconst CWD = "/workspace", so it could only run wherethat path exists and is writable — on macOS it cannot be created at all. This is the seam
pi-mentor-runner.tshas had all along, and the shape here is now identical to it:That asymmetry is worth naming, because it is the likeliest reason this side of the runtime has no
harness-level tests while the mentor side does.
A bug this PR introduced and then removed, worth knowing about. My first version added a
second
ISSUE_REVIEW_CHANNELStoFeedbackCompositionInputs, set to the two longitudinal lanes,inferred from a prose comment. That was wrong twice over:
IssueReviewHandler:261parsesFeedbackChannel.IN_CONTEXTunits to build the note it posts, so excluding that lane would havestarved the only one the issue path reads — and the handler already had its own constant, with a test
pinning it. The duplicate is gone; the existing constant is used.
SandboxLayoutSyncTestchanged, and it is the part most worth arguing about. It pins runnerliterals against
SandboxLayoutby grepping the source. It asserted the concatenated"/workspace/task.json", which a derived path cannot contain. My first attempt kept a redundantliteral alive purely so the grep would match — production code bent around a test. That was wrong, so
the test now pins the root and the leaf separately, which is the style its own practices-index
assertion already used. Both constants are still pinned; if you would rather the ABI check moved to a
generated constant, say so.
The live harness could not run at all, and two rot points are repaired here so it can: a practice
fixture kept its pre-rename filename, and
inputs/manifest.json— which the runner refuses to startwithout, because it gates every citation — was never staged. Both rotted unnoticed because
@Tag("live")tests do not run in CI. With those fixed I drove the real runner against a live modellocally; it found the planted secret (
PRESENT / CRITICAL).A known asymmetry.
PullRequestReviewHandlergets a test asserting the staging call happens;IssueReviewHandlerdoes not. The issue test class has noprepareInputsfixture, and building onefor a single assertion would add more scaffolding than signal. The issue side is not unguarded — the
request shape it stages is already covered — but the call site itself rests on the PR-side test and
review. Say the word if you would rather have the fixture.
What this PR does not do. Composition needs an observation-admission round trip to the server, so
an LLM-only harness cannot exercise the composing turn — I removed a live test that asserted it,
because a test that cannot pass is worse than no test. The natural next step is a database-backed test
of the composed-note path, and I deliberately stopped short:
PracticeDetectionPipelineIntegrationTeststages an empty
unitsarray, manufacturing the digest without asking delivery to place anything,which is exactly why a DB-backed test stayed green while production placed nothing. Closing it means
satisfying a contract spread across several files — a unit needs
title,nextStepand aplacement;basedOnmust ground against a staged observation of the same practice — and I wouldrather land that deliberately than guess at it here.
Adjacent debt, deliberately not in scope:
PullRequestReviewHandlerlines ~501–541 are unreachable:processObservationsis only ever calledwith
admissionOnly=true.failOnViolation=false, no lifecycle binding, no CI job. It reports232 violations, 116 of them
UnnecessaryImport. Two of those were the unused imports in these veryhandlers; refactor: replace Biome's linter with oxlint and strengthen quality gates #1479 has since removed them, which is why this branch had to add them back.
foldConfusablesis TypeScript-only andapplied only to the non-diff branch, and Java's
String.lines()strips\rwhere TS'ssplit("\n")keeps it. The sandbox admits a claim; the server re-verifies differently and withholds it. For the
record, NFKC does not fix the Unicode half — it maps U+2011 to U+2010, not to ASCII
