Feedback audit ledger — actionable feedback addressed; latest head green and clean/mergeable. Audited issue comments, review bodies, inline comments, check summaries and annotations. Docstring fixes:
Validation after documentation patch: 17 focused inbound tests, typecheck, lint, build and five actual cloud Queue events → signed receiver → subscriber inbox pass. Prior complete engine suite: 1154 tests. All three inline threads replied to and resolved. Empty author review bodies add no findings. REST verification: 3b7b6d0 is OPEN, mergeable=true, mergeable_state=clean. All executable CI checks pass; no new feedback since the audit. Stale automated docstring measurement is explicitly documented above and accepted as an external non-actionable limitation. Cloud #237 was merged externally and auto-deployed to dev; production health still showed pre-fix f3a2009. Recovery order: receiver #447 deploy/verify → cloud production deploy/verify → authorized binding reprovision. No merge, deployment, semantic subscription creation, reprovisioning or production probe performed by this agent. |

@coderabbitai The latest summary still measures 62.5% after 3b7b6d0. Please identify the exact three undocumented functions and their locations from the docstring coverage check. JSDoc now directly precedes both route callbacks, deriveRelayfileInboundSecret, eventMatchesSubscription, the proof request helper, makeStack, signedHeaders, and the new replay emit helper. We need the actual missing-function list to address the warning without unrelated documentation churn. |

@coderabbitai Your source audit confirms all eight functions are documented at 3b7b6d0, while the top-level coverage warning is stale. If supported, please rerun only the docstring pre-merge check and refresh that summary. Do not enable usage-based billing or alter review configuration. Otherwise we will wait for the stated free review reset. |

Tip For best results, initiate chat on the files or code changes.
I will not trigger a full review, enable usage-based billing, or change review configuration. The current source audit supports waiting for the free review reset or for a new CI check that publishes refreshed docstring coverage. You are interacting with an AI system. |

Relayfile GitHub PR events use titled directories and sibling comment/review paths, so the inbound receiver's literal
/pulls/1815/**filter silently skipped them. Match the exact PR identity for newly authorized numeric PR targets, while retaining literal behavior for legacy callbacks and generic/file-level globs.Companion: https://github.com/AgentWorkforce/relayfile-cloud/pull/237. Cloud fanout and this receiver must agree. Deploy the receiver first, then the cloud companion (or coordinate atomically), then reprovision the existing binding through the subscribe flow with full exact-repository read authorization. Reprovisioning creates a new HMAC-bound receiver opt-in and a cloud subscription with persisted authorization. Do not edit an old callback URL or legacy DB flag. No Relay CLI source change is required; neither production binding nor service was changed here.
The target creation route requires a workspace key. Its server-issued
github_pr_identity=1parameter uses a versioned, structurally encoded signing domain, disjoint from legacy derivation; legacy secrets cannot add the flag, and new signatures cannot omit it. Event-body opt-ins are ignored. Matching is restricted to GitHub provider-sync events and exact owner/repository/PR identities.Validation:
RELAYFILE_PROOF_EVENTS=/tmp/events.json, then this built engine'spackages/engine/scripts/prove-github-cloud-inbound.mjswith the same variable (Node 22).Production GitHub-to-agent delivery awaits both deployments and authorized reprovisioning. Existing deletion-event policy is unchanged; the historical processing-failure counter and separate CLI connection-status symptom are not established causes of this path-matching failure.
Note
Medium Risk
Changes inbound webhook authentication, path matching, and secret derivation for GitHub PR bindings—security-sensitive ingress—but legacy targets are unchanged and opt-in is sealed in HMAC.
Overview
Fixes Relayfile GitHub PR inbound subscriptions so newly provisioned numeric PR subtree targets (
/github/repos/<owner>/<repo>/pulls/<n>/**) accept titled pull paths and related provider-sync events (comments, reviews) tied to the exact stable PR reference, instead of only literal glob paths.Authorization is HMAC-bound: workspace-key provisioning sets
github_pr_identity=1on the callback URL and derives signing secrets from a versioned JSON label disjoint from legacy targets. Legacy callbacks stay literal; query tampering or body-level opt-ins cannot enable semantic matching without the matching secret.Matching runs through
eventMatchesSubscription(literal glob first, then GitHub identity rules for authorized targets). OpenAPI, README, and changelogs document reprovisioning; a cloud Queue integration script and expanded inbound tests cover isolation, replay dedupe, and signature boundaries.Reviewed by Cursor Bugbot for commit 3b7b6d0.
