…y limit @opencode-agent mentions could not enqueue because both the first-hop wrapper payload and the merge-scheduler forwarder sent 14 client_payload keys. GitHub's repository_dispatch API allows 10 and returns HTTP 422. Keep identity on both hops, bind review-only flags in the invocation claim, hardcode those flags in the wrapper, and fail closed if a payload grows past 10 keys.

Pull request overview
OpenCode reviewed the current-head bounded evidence and found no blocking issues.
Findings
No blocking findings.
Summary
Approval sufficiency: Affirmative — PR #1115 fixes the HTTP 422 failure for @opencode-agent mention pings by trimming both repository_dispatch hops to <=10 client_payload keys in scripts/ci/agent_mention_router.py and .github/workflows/agent-mention-opencode-dispatch.yml, with docs/automation/review-agent-comment-invocation.md:48 updated and three test files added/updated. Verification posture: Coverage execution evidence reports Result: PASS (supported repository test suites passed; configured docstring gates passed or advisory); no completed failed GitHub Checks at head; no unresolved review threads; mergeStateStatus behind is not a conflict. Linter/static: repository contract provides pytest+coverage --fail-under=100 (coverage_commands), interrogate (docstring_commands), bandit/pip_audit (security_commands); the PASSed coverage run covers the changed Python paths per Coverage execution evidence. TDD/regression: new tests/test_agent_mention_dispatch_payload_limit.py (141 lines) plus updated tests/test_agent_mention_complete_payload_binding.py and tests/test_agent_mention_router.py bind the 10-key cap and the complete payload shapes; suite passed per Coverage evidence. Coverage: Coverage execution evidence — Result: PASS, supported repository test suites passed. Docstring coverage: Coverage execution evidence — configured repository docstring gates passed or docstring coverage was advisory. DAG: base-to-head flowchart via CodeGraph changed-scope exploration (42 symbols, 4 files): mention event -> agent_mention_router.py repository_dispatch_body guard -> agent-mention-opencode wrapper (hardcoded TRIGGER_REVIEWS/REVIEW_DISPATCH_LIMIT/ENABLE_AUTO_MERGE/UPDATE_BRANCHES/MERGE_MODE) -> merge-scheduler forward with exactly 10 client_payload keys; reflects the changed head flow vs base, which forwarded 14-key payloads rejected with 422. PoC/execution: non-web workflow/script surface; no browser receipts applicable; trusted execution anchor is the PASSed repository test run in Coverage execution evidence. DDD/domain: dispatch/claims domain — payload builders centralized through repository_dispatch_body, a single enforcement point for the platform cap. CDD/context: the wrapper workflow remains the only review-only gate; the five merge-behavior flags moved from caller-controlled client_payload into wrapper-hardcoded env, tightening the trust boundary. Similar issues: CodeGraph shows no other callers beyond the two payload builders and their tests; no similar open findings. Claim/concept check: the GitHub 10-key client_payload cap is stated consistently in the PR body, the updated docs bullet, and the new limit test; independent verification of GitHub's REST documentation was unavailable to this isolated model (source limitation), but all in-repo contracts agree and the forward payload sits at exactly 10 keys. Standards search: repo-native contract only; no external standards material required for this workflow/script change. Compatibility/convention: naming conforms — REPOSITORY_DISPATCH_CLIENT_PAYLOAD_MAX_KEYS (SCREAMING_SNAKE_CASE constant) and repository_dispatch_body (snake_case function) are multi-word and idiomatic; no new DB/API/route/serialized identifiers; pr_number and source_comment_id are pre-existing GitHub-native identifiers with no new sequential-id exposure. Breaking-change/backcompat: first-hop opencode payload drops only the five review-only flag keys (keeps requested_agent and requested_by, so the wrapper's unchanged PAYLOAD_AGENT == REQUESTED_AGENT validation still passes); the merge-scheduler forward drops requested_agent/requested_by while keeping agent_invocation_key and source_comment_id, exactly as documented; wrapper env REQUESTED_BY/PAYLOAD_AGENT reads are unchanged. Implementation completeness: repository_dispatch_body is fully implemented (ValueError when len(client_payload) > 10) and both noema_payload and opencode_payload are wired through it; the removed claim = agent_invocation_claim(...) line was a dead local assignment in base; no placeholders. Performance: negligible — constant-time key-count check per dispatch. Developer experience: operator docs now explain why review-only constants are not copied onto the first hop and exactly what the forward keeps; no diagnostic information lost. User experience: non-web interaction surface — review-comment mention dispatch output; hardcoded flags guarantee mention pings can no longer silently fail to enqueue due to payload size or carry caller-controlled merge behavior. Visual/DOM: non-web change — no DOM/UI surface; reviewed workflow/review-comment output instead. Accessibility/i18n: no UI or motion changes; not applicable to this workflow/script surface. Supply-chain/license: no dependency additions/removals; no new packages. Packaging: no packaging changes; python test contract is python3 -m pytest tests per Review execution contracts. Security/privacy: invocation validation (agent identity, 64-hex invocation key, repository allowlist, SHA/base-branch regexes) is unchanged; the merge-behavior flags are now wrapper-hardcoded, shrinking the caller-controlled dispatch surface; no secrets or tokens touched.
Approval sufficiency: bounded evidence supplied affirmative approval evidence for changed files, coverage/docstring posture, risk surfaces, and current-head verification; approval is not based merely on the absence of known blockers.
Verification posture: CodeGraph evidence was initialized and bounded current-head evidence reviewed for changed-file evidence including .github/workflows/agent-mention-opencode-dispatch.yml, docs/automation/review-agent-comment-invocation.md, scripts/ci/agent_mention_router.py, tests/test_agent_mention_complete_payload_binding.py, tests/test_agent_mention_dispatch_payload_limit.py, and 1 more.
Linter/static: workflow/static review evidence is bounded by the current-head GitHub Checks gate and changed-file evidence.
TDD/regression: coverage execution evidence and focused changed hunks were reviewed from bounded-review-evidence.md.
Coverage: coverage execution evidence reports supported repository test suites passed.
Docstring coverage: coverage execution evidence reports configured repository docstring gates passed or docstring coverage was advisory.
DAG: CodeGraph/source-backed behavior map connects .github/workflows/agent-mention-opencode-dispatch.yml to the affected review, runtime, or workflow path and required checks.
PoC/execution: coverage-evidence job executed on the current head and reported PASS.
DDD/domain: workflow and repository-governance invariants were reviewed against changed files in bounded evidence.
CDD/context: CodeGraph evidence, changed-file history, and focused hunks were reviewed from bounded-review-evidence.md.
Similar issues: changed-file history evidence was reviewed for comparable local precedents.
Claim/concept check: bounded evidence, repository source, current-head workflow evidence, and, where numeric, scientific, statistical, or literature-backed claims are affected, original-paper/formula evidence and parameter-recovery expectations were used for claims.
Standards search: standards and external-source claims require trusted bounded source evidence prepared outside the isolated model process; no evidence-backed standards blocker is present in bounded evidence.
Compatibility/convention: changed workflow/script conventions, object naming, and reserved-word safety for schema/API/config/code surfaces were checked in bounded evidence.
Breaking-change/backcompat: deployment evidence and changed-file history were checked for backward-compatibility risk.
Performance: changed surfaces were checked for performance risk in bounded evidence.
Developer experience: changed automation, review, test, setup, and maintenance surfaces were checked for helpful or obstructive DX impact in bounded evidence.
User experience: connected user, operator, API, CLI, documentation, review-comment, status-check, rendering, and workflow-reader behavior was checked for contradictions against code, docs, and tests in bounded evidence.
Visual/DOM: deterministic repair does not infer browser runtime execution; source-backed DOM/UI evidence and trusted workflow receipts were reviewed when present, and non-web surfaces used API/CLI/log/docs/workflow evidence instead.
Accessibility/i18n: accessibility, localization, and human-readable text surfaces were checked where UI, CLI, API message, docs, logs, or review text changed.
Supply-chain/license: dependency, package, model, container, and external-tool changes were checked in bounded evidence.
Packaging: package, build, test, lint, and security contracts were checked in bounded evidence.
Security/privacy: workflow-token, review-gate, and repository-automation security/privacy boundaries were checked in bounded evidence.

Operational-acceptance follow-up from the read-only Orgmetra dependency boundary: the merged router repair is on protected Reproductions after the integrated repair:
This is downstream evidence only; Orgmetra is not changing central router source/settings. Please treat this as the post-merge operational-acceptance RED required by this PR: trace each source comment through trusted actor/allowlist evaluation, exact-head resolution, durable invocation claim, local queue admission, wrapper dispatch and acknowledgement. Smallest acceptable GREEN proof is a source-comment receipt/durable exact-name invocation artifact plus the matching OpenCode wrapper start for the same repository/PR/head, with review-only controls preserved and no branch-update/merge authority. |

@opencode-agentcomments, including issue comment5328489083on PR #1124, could remain unacknowledged and never start the existing OpenCode review path. The failure occurs before model execution.Root cause
Two independent central-router defects produce the same operator-visible symptom:
repository_dispatchhops carried 14 top-levelclient_payloadproperties. GitHub accepts at most 10 and rejects a larger payload with HTTP 422 before the trusted wrapper starts.issue_commentroutes and the five-minute organization sweep shared one workflow-level concurrency group. Under the default single-pending contract, a new sweep could replace a pending interactive request before exact-head resolution, durable ledger claim, dispatch, or acknowledgement.This is not a maintainer-trust, model, allowlist, or review-verdict defect.
