glm-5.3-flash e2c255d40c docs(tasks): decompose review-002 into 24 tasks (23 implementation + 1 bracketed follow-up)
Decomposition of docs/reviews/002-post-remediation-review.md per its
5-unit remediation plan:

- Unit 1 (security-critical): gw15-publish-body-cap,
  prj16-schema-via-call (CF-004 filed alkcall-side), fwd13-dot-segments,
  fwd16-missing-capability, oai11-ref-memoization
- Unit 2 (timeout/terminality): ws13-idle-progress,
  fwd15-stream-timeout, cli01-retry-after-budget, con17-mcp-pagination,
  con18-wss-sweep-exit
- Unit 3 (projection/docs): projection-truthfulness, mcp-batch-cap,
  gw16-status-drift
- Unit 4 (spec-import): yaml-normalization, oai13-path-item-wildcards,
  import-loudness-cluster, js01-placeholder-check,
  fwd17-19-contract-decisions
- Unit 5 (WS polish + tests): con18b-ws-polish,
  client-policy-wire-tests, cov-deployment-knobs, cov13-dead-code,
  srv11-srv12-router-ordering
- review-002-bracketed-followup: tentatively planned post-bulk pass
  (stale-check, OQA-18 enforcement decision, CON-08/09 close() lever,
  cross-crate re-checks) — deliberately not serialized against the
  bulk

Also: review-002 numbering repair (CON-14 was double-booked; MCP
pagination now CON-14, from_wss monitor renumbered CON-18, missing
CON-14 section added).

taskgraph: 66 valid, no cycles; 24 pending (all review-002);
gen-1/gen-2 parallel waves identified; workflow-cost hotspots are
prj16 (12.8) and ws13 (11.1), both carrying the reviewed slicing
guidance in their Notes.

Description

Review 002 PRJ-22 [minor]. The MCP batch tool has no cap on the calls array (to_mcp.rs:215-247 executes serially) while HTTP /batch rejects at 101 (routes.rs:173-184, MAX_BATCH_OPERATIONS). A 10,000-entry MCP batch occupies the dispatch spine serially (each invoke up to the 30 s deadline) — the doc (PRJ-09's fix) advertises no limit either.

Acceptance Criteria

  • The batch tool enforces the same MAX_BATCH_OPERATIONS cap (share the constant; do not duplicate the literal) — over-cap → structured INVALID_INPUT-family error consistent with the tool's other argument errors (including retryable, per PRJ-13)
  • Tool description states the limit (mirroring how /batch docs it) — ADR-041 shape unchanged (4 fixed tools)
  • Test: over-cap calls array → structured error, no dispatch happened (spy/gateway-count assert via the existing invoke_tool harness)
  • cargo test --features mcp, cargo clippy --all-features --all-targets -- -D warnings, cargo fmt --check pass

References

  • docs/reviews/002-post-remediation-review.md (Part F', PRJ-22)
  • src/adapters/to_mcp.rs:215-247 (the loop), src/gateway/routes.rs:42,173-184 (the cap to share)
  • tasks/adapters/review-001-mcp-tool-fidelity.md (the PRJ-07..10/13 work whose conventions to follow)

Notes

One of the smallest tasks in the batch — a good first warm-up slice or fold-in candidate if a session runs short (but keep the commit separate; it is its own unit of work).
