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 JS-01 [major]. from_jsonschema's eager placeholder-binding check is skipped when input_schema has no properties key: spec_name_references_undeclared (from_jsonschema.rs:166-188) hits if properties.is_empty() { return false; } at :173-175. So:

FromJsonSchema::new(spec_with_input_schema_type_object_no_properties,
                    path_template = "/widgets/{id}")

passes construction — then every call fails ({id} unbound → INTERNAL at forward.rs:441-446; a peer-supplied id key → INVALID_INPUT). The from_openapi equivalent (unbound_placeholders, from_openapi.rs:36-57) handles the empty case correctly: with no declared properties, any placeholder is unbound. The existing test (from_jsonschema.rs:699-724) covers only the properties-present case.

Acceptance Criteria

  • Drop the is_empty early return (or return true for placeholders when properties are empty — same semantics as the from_openapi path)
  • Test: FromJsonSchema::new with a no-properties schema + {id} template fails at construction with the placeholder error; a no-properties schema with a placeholder-free template still constructs fine
  • cargo test, cargo clippy --all-targets -- -D warnings, cargo fmt --check pass

References

  • docs/reviews/002-post-remediation-review.md (Part E', cluster item JS-01; Test-gap 11)
  • src/adapters/from_jsonschema.rs:166-188 (the early return), :77-93 (the construction-time validation), :699-724 (the present-props test)
  • src/adapters/from_openapi.rs:36-57 (the correct reference implementation)
  • docs/architecture/decisions/066-from-jsonschema-as-http-adapter.md

Notes

One-line fix + one test. Explicitly approved to fold into any commit that is already touching from_jsonschema.rs (e.g. the wire-tests task) if a session prefers — but if touched standalone, keep it its own commit per the small-units convention.
