From 1648a5890a7fccf7aad3d59e5206eae659385c94 Mon Sep 17 00:00:00 2001 From: Mark Kreyman Date: Sat, 26 Sep 2026 16:02:21 -0600 Subject: [PATCH 1/3] US-45.3: review dispatch, checkpoint-bound findings and a server-side round ceiling An orchestrator places a review, which mints the reviewer's dispatch as a sibling of the implementer's; findings and verdicts are accepted only on the key that placed dispatch minted, bound to the review and the checkpoint it reads. The claimant records fixes naming the findings they answer. Round count and ceiling are computed from thread_entries: round 3 only when a round-2 finding is introduced by a round-1 fix checkpoint, never round 4, and a ceiling with a material finding records review_ceiling and escalates the delivery stage. Refusals have their own codes, never self_review_blocked. Ships the MCP tools (2.106.0). The runner contract bump (AC-45.3.8) remains. --- .claude/skills/chain-of-custody/SKILL.md | 13 + CHANGELOG.md | 19 + lib/loopctl/custody/context_surface.ex | 2 +- lib/loopctl/tenants/tier_capabilities.ex | 5 +- lib/loopctl/threads.ex | 127 +- lib/loopctl/threads/entry.ex | 24 +- lib/loopctl/threads/review.ex | 29 + lib/loopctl/threads/reviews.ex | 1216 +++++++++++++++++ .../controllers/thread_controller.ex | 20 +- .../controllers/thread_review_controller.ex | 406 ++++++ lib/loopctl_web/router.ex | 8 + mcp-server/CHANGELOG.md | 15 + mcp-server/README.md | 7 +- mcp-server/index.js | 184 ++- mcp-server/lib/threads.js | 137 +- mcp-server/package-lock.json | 4 +- mcp-server/package.json | 2 +- mcp-server/test/router-routes.json | 5 + mcp-server/test/threads_tool.test.js | 156 ++- .../20260926160000_create_thread_reviews.exs | 126 ++ test/loopctl/threads/reviews_test.exs | 819 +++++++++++ .../thread_review_controller_test.exs | 241 ++++ test/support/fixtures.ex | 76 ++ 23 files changed, 3589 insertions(+), 52 deletions(-) create mode 100644 lib/loopctl/threads/review.ex create mode 100644 lib/loopctl/threads/reviews.ex create mode 100644 lib/loopctl_web/controllers/thread_review_controller.ex create mode 100644 priv/repo/migrations/20260926160000_create_thread_reviews.exs create mode 100644 test/loopctl/threads/reviews_test.exs create mode 100644 test/loopctl_web/controllers/thread_review_controller_test.exs diff --git a/.claude/skills/chain-of-custody/SKILL.md b/.claude/skills/chain-of-custody/SKILL.md index 1fd3f73d..f5c3bf7c 100644 --- a/.claude/skills/chain-of-custody/SKILL.md +++ b/.claude/skills/chain-of-custody/SKILL.md @@ -145,6 +145,19 @@ column and not a `metadata` key on purpose**: `metadata` is cast by `Story.updat REPLACED wholesale by `PATCH /api/v1/stories/:id`, so one ordinary orchestrator request erased the marker and handed the launder path back.

It revokes the review's dispatch and key, so a resend is 401; read the thread instead. A ceiling reached with a critical, high or medium finding returns a `review_ceiling` escalation.

Resets it to `agent_status: pending` with `assigned_agent_id` cleared AND makes the delivery stage row follow the release back to `queued`. **A delivery story then goes to `escalated`, not back to the queue** (loopctl US-44.4): an operator taking a story back is a human decision, so a release that leaves the stage row at `queued` escalates it over `operator_released` in the same transaction, spending no attempt against the retry ceiling — it is not left in the queue behind the human's back. Put it back to work with `resolve_escalation` `to: queued`, which releases (a no-op by then) AND re-contracts. A story with no delivery stage row is simply left `pending`. 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..46a20d13 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).

Ceiling: placement applied the reverse of the dispatch ceiling. Both now call Dispatches.lineage_within_caller?/3, the one copy; the caller must be the implementer's parent or an ancestor. The on-chain check it made unreachable is gone. 2. Round 3 is decided at the round-2 verdict: only fixes with a lower seq count. 3. A verdict revokes every other open review of its round; a verdict refused review_round_superseded revokes its own dispatch. 4. Moduledoc and MCP text: a verdict resend is 401 once the key is revoked; the answer-from-row path remains for a failed revocation only. 5. The ceiling escalation goes through Escalations.escalate_as_control/3, which shares escalate/3's transition, replay and stale_stage recovery minus the claimant check. 6. Judgement idempotency is scoped to the review, in the replay lookup and in a review-scoped unique index; the author-scoped index now excludes judgements. 7. LoopctlWeb.ThreadHTTP is the one render/param helper for both thread controllers; location_untrusted is rendered on every thread read. 8. The judgement CHECK refuses a NULL finding_ids. 9. An implementer dispatch that does not resolve is 409 unresolvable_dispatch_lineage. 10. The review payload carries the latest 100 fixes with fixes_truncated, their findings read by join rather than an id list. Mutations (bin/mutate.sh, 0 = caught): 62 run, 59 caught. M33 survives (RLS on agents), N02 survives against the dispatch controller suite (its ceiling test does not probe the prefix direction; caught by the review suite as N01). --- CHANGELOG.md | 2 +- lib/loopctl/delivery/escalations.ex | 22 +- lib/loopctl/dispatches.ex | 31 ++ lib/loopctl/threads.ex | 24 +- lib/loopctl/threads/entry.ex | 1 + lib/loopctl/threads/reviews.ex | 309 ++++++++++-------- .../controllers/dispatch_controller.ex | 30 +- .../controllers/thread_controller.ex | 79 +---- .../controllers/thread_review_controller.ex | 86 ++--- lib/loopctl_web/thread_http.ex | 80 +++++ mcp-server/README.md | 4 +- mcp-server/index.js | 11 +- .../20260926160000_create_thread_reviews.exs | 36 +- test/loopctl/threads/reviews_test.exs | 175 +++++++++- .../thread_review_controller_test.exs | 7 + test/support/fixtures.ex | 25 +- 16 files changed, 608 insertions(+), 314 deletions(-) create mode 100644 lib/loopctl_web/thread_http.ex diff --git a/CHANGELOG.md b/CHANGELOG.md index b0150503..4bdb4edc 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -21,7 +21,7 @@ All notable changes to loopctl are documented here. `introduced_by` and `finding_ids` columns on `thread_entries`.

A caller with an empty lineage places a review only as the operator, decided by Placement.may_mint_session_dispatch/2 (now public, the one copy); a legacy key is 409 caller_lineage_required. 2. The reviewer may not be the agent of any dispatch on the implementer's lineage or the review's own ancestry, checked at placement, under the record lock, and on every judgement write. 3. The author-scoped idempotency lookup excludes judgements, matching the partial index. 4. Placement is prepare then commit; the round and the separation are re-decided under the thread lock when the review is recorded. 5. review_round_superseded and reviewer_not_separate end the review and revoke its dispatch, for findings and verdicts. 6. The record revokes the minted dispatch on a refusal, on busy when no row landed (a row that did land is answered), and on a raise before re-raising. 7. The ceiling escalation takes a new control-only review_ceiling stage edge with a control label; the runner-reportable set is unchanged. 8. The review authority (a review of this story) is decided before the payload. 9. Reviews uses Threads.story/2 and Threads.checkpoint_of/3; its copies are gone. 10. The dispatch ceiling suite now tests the prefix direction. 11. The migration's down refuses, with an explicit Ecto.MigrationError, when judgement keys shared across reviews would break the per-author index it restores. --- CHANGELOG.md | 4 +- lib/loopctl/delivery/escalations.ex | 18 +- lib/loopctl/delivery/placement.ex | 13 +- lib/loopctl/delivery/stage_machine.ex | 15 +- lib/loopctl/threads.ex | 40 +- lib/loopctl/threads/reviews.ex | 342 ++++++++++++++---- .../controllers/thread_review_controller.ex | 11 +- mcp-server/README.md | 6 +- mcp-server/index.js | 11 +- .../20260926160000_create_thread_reviews.exs | 21 ++ test/loopctl/threads/reviews_test.exs | 228 +++++++++++- .../dispatch_lineage_ceiling_test.exs | 44 +++ .../thread_review_controller_test.exs | 4 + test/support/fixtures.ex | 5 +- 14 files changed, 640 insertions(+), 122 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 4bdb4edc..db060b9e 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -16,12 +16,14 @@ All notable changes to loopctl are documented here. its round and revokes the review's dispatch and key, round 3 is placeable only when a round-2 finding's `introduced_by` names a checkpoint a round-1 fix is carried by, and there is never a round 4; a ceiling reached with a critical, high or medium finding records a - `review_ceiling` escalation and escalates the story's delivery stage.

Resets it to `agent_status: pending` with `assigned_agent_id` cleared AND makes the delivery stage row follow the release back to `queued`. **A delivery story then goes to `escalated`, not back to the queue** (loopctl US-44.4): an operator taking a story back is a human decision, so a release that leaves the stage row at `queued` escalates it over `operator_released` in the same transaction, spending no attempt against the retry ceiling — it is not left in the queue behind the human's back. Put it back to work with `resolve_escalation` `to: queued`, which releases (a no-op by then) AND re-contracts. A story with no delivery stage row is simply left `pending`. 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`.
