Round 3 is placeable only when a round-2 finding's + `introduced_by` names a checkpoint a round-1 fix is carried by, counting only fixes written + before the round-2 verdict, so the decision is made once and a later fix cannot reopen it. + Round 4 never is. + + A review is over when its verdict commits, and so is every other review placed for that round + or an earlier one; all of their dispatches and keys are revoked then, and a verdict refused + `review_round_superseded` revokes its own.

A story parked at `claimed` with nobody on it is the residue of a compensation that did not complete, not what a refused dispatch normally leaves: placement releases the claim inline when a runner refuses, and the claim lease releases it unattended once `claimed_until` passes — reach for this to get it back now, or when both of those left it held. Requeues from any stage a claim holds; a stage no claim holds keeps its stage and is rebound to the new epoch; `done` and `failed` are untouched. For an ESCALATED story use `resolve_escalation` instead — that one releases AND re-contracts, so its `queued` really is placeable. Requires an orchestrator-ROLE key: the action is `exact_role: :orchestrator`, so a user or superadmin key is 403'd like any other non-member. Put it in `LOOPCTL_ORCH_KEY` (which is then the key sent, and a global `LOOPCTL_API_KEY` does not displace it) or, with no orchestrator key set, in `LOOPCTL_API_KEY`. The orchestrator key must be linked to a registered agent (400 otherwise) and the tenant must be human-anchored (403 `custody_tier_required` otherwise). Does not touch `verified_status`. Run again on an already-pending story it is still an operator's release: a row stranded behind the story's claim epoch is rebound, an in-flight row is requeued, and a row then at `queued` — including one already sitting there — is escalated over `operator_released`, as on the first run; a row already escalated, or anywhere else at that epoch, is left alone. Every 500 means the whole release rolled back and the story is still claimed: `audit_chain_append_failed` (the escalation's chain entry was refused) is a server-side condition a re-run meets again until an operator acts; `force_unclaim_failed` (the server log names the step) — call it again. A 422 means the release write itself was rejected. No request body. Required: `story_id` (refused locally if it is not a UUID). | | `merge_precondition` | **Run the merge gate over a story's real pull request** (`POST /api/v1/stories/:id/merge-precondition`). Both delivery gates run again over the diff that exists, plus custody, the 12-file / 1000-line hard bound, the head-has-not-moved check and the self-deploy exclusion; the story must be at stage `ci`. **Gate A reads what triage persisted, never the caller**: the lens verdicts recorded with the story's most recent triage, or a human's re-queue of a Gate A escalation — `gate_a_inputs` on the answer says which, and `missing` refuses with `gate_a_inputs_missing`. This tool sends no trio. Decisions: `allow` (recorded against the head; the only thing that licenses a merge), `refuse` (the story is escalated before this returns), `already_merged`, `head_moved`, `unevaluated` (503 with `Retry-After`). Requires an orchestrator- or user-ROLE key (`exact_role: [:orchestrator, :user]`, so an agent key is 403'd); `LOOPCTL_ORCH_KEY` is sent when set, else `LOOPCTL_API_KEY`. 403 `custody_tier_required` without a human anchor, 404 for an unknown story, 422 when the story is not at `ci`. Required: `story_id` (refused locally if not a UUID) and `claim_epoch` (a non-negative integer, refused locally otherwise); optional `effect_proof`. | | `intake_source_enroll` | **Bind a GitHub repository to a work project and mint its webhook secret** (`POST /api/v1/intake/sources`) — the step that gives the delivery loop an input, and the row `place_dispatch` reads `repo` and `base_branch` from (its 409 `no_intake_source` means this has not been done; 409 `ambiguous_intake_source` means it has been done twice). **The secret is returned ONCE and can never be read again** — the column is encrypted at rest and redacted on the schema, so no other tool carries it and losing it costs a revoke, a re-enrolment and a reconfigured GitHub webhook. **This tool does not return it either:** a tool result lands in the transcript and the audit log, so it is written to the required `secret_file` with mode 0600 (the handling `runner_enroll` gives a runner credential) and the result carries the source row, the `webhook_url` and that path. The path is reserved before the request, so an existing file or an unwritable directory is refused with nothing enrolled, and any outcome that is not a clean creation withholds the response body — an unparsed 2xx body IS the secret. A 2xx carrying the source and the secret but no webhook path is RECOVERED rather than discarded (the path is derived from the source id, flagged `webhook_url_derived`), and an outcome that proves a source id but no usable secret REVOKES that source rather than leaving it holding the repository's unique slot. Then configure GitHub: Payload URL = the returned `webhook_url`, content type `application/json`, Secret = the contents of the file, and the **Issues** event only — `gh api repos/OWNER/REPO/hooks -f name=web -f config[url]= -f config[content_type]=json -f config[secret]="$(cat )" -f 'events[]=issues'`. Every later delivery failure is the SAME 401 `invalid_signature` — unknown or revoked source, suspended tenant, missing or wrong signature, or a payload whose `repository.full_name` does not match — so the webhook's Recent Deliveries tab cannot tell you which. `base_branch` is set HERE: it defaults to `master` when the body does not name it, so name `main` for a repository created on GitHub since 2020 or every dispatch is cut from a trunk that does not exist. It is not nullable (a dispatch must name a branch), so null or blank is refused rather than falling back to the default, and `intake_source_update` changes it afterwards. Refusals: 403 `api_key_mint_forbidden` if your key was minted by a dispatch (this mints a credential belonging to no lineage, so only an unlineaged operator key may), 403 `custody_tier_required` on an agent-rooted tenant, 422 for a repository that is not `owner/name`, an ACTIVE source already binding it, a project that is missing / archived / not a work project, or a `target_epic_id` outside that project. Required: `repo_full_name`, `project_id`, `secret_file`. Optional: `base_branch`, and `target_epic_id` — **omitting the epic is not a neutral default**: with no epic every triaged report is escalated to a human and every record stays `pending_triage` until `intake_source_update` names one. Requires `LOOPCTL_USER_KEY`. | diff --git a/mcp-server/index.js b/mcp-server/index.js index d6f14af6..b369a185 100755 --- a/mcp-server/index.js +++ b/mcp-server/index.js @@ -48,9 +48,14 @@ import { enrollRunner, listRunners, revokeRunner, runnerPool } from "./lib/runne import { claimLeaseNotice, renewStoryClaim as renewStoryClaimRequest } from "./lib/claim-lease.js"; import { escalateStory as escalateStoryRequest, escalationNotice } from "./lib/escalation.js"; import { + getReview as getReviewRequest, getThread as getThreadRequest, + placeReview as placeReviewRequest, recordCheckpoint as recordCheckpointRequest, recordEntry as recordEntryRequest, + recordFinding as recordFindingRequest, + recordFix as recordFixRequest, + recordVerdict as recordVerdictRequest, } from "./lib/threads.js"; import { forceUnclaimStory as forceUnclaimStoryRequest, @@ -1241,6 +1246,27 @@ async function threadEntry(args) { return toContent(await recordEntryRequest(args, { apiCall: threadApiCall })); } +// US-45.3: review on the thread, on the same exact-key path. +async function threadPlaceReview(args) { + return toContent(await placeReviewRequest(args, { apiCall: threadApiCall })); +} + +async function threadReviewGet(args) { + return toContent(await getReviewRequest(args, { apiCall: threadApiCall })); +} + +async function threadFinding(args) { + return toContent(await recordFindingRequest(args, { apiCall: threadApiCall })); +} + +async function threadVerdict(args) { + return toContent(await recordVerdictRequest(args, { apiCall: threadApiCall })); +} + +async function threadFix(args) { + return toContent(await recordFixRequest(args, { apiCall: threadApiCall })); +} + async function startStory({ story_id, capability }) { // Cache first, then DELIVERY of the token claim already minted, then recovery // (which mints a fresh one).
