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 OAI-13 [major]. Three common real-world OpenAPI shapes are
still silently mishandled (verified at `openapi_spec.rs:276-336` +
`from_openapi.rs:136-145`):
1. **Path-item-level `parameters`** (shared params declared next to
the path key — extremely common in real specs) never merge into
operations → `{id}` unbound → the whole import fails with a
*misleading* diagnosis (the skip filter at :314-320 explicitly
whitelists `"parameters"` out of the unsupported-methods warning,
so nothing names the cause).
2. **Response wildcard keys**: `"2XX"` is missed by the SSE-detection
success sweep (an SSE stream under `2XX` imports as a giant-text
Mutation — the exact OAI-06 misbehavior, one spelling away);
`"4XX"/"5XX"` error keys drop silently with the generic warn (the
test at from_openapi.rs:840 enshrines silent `5XX` dropping).
3. **Top-level `webhooks`** silently vanish from mixed documents.
## Acceptance Criteria
- [ ] Path-item `parameters` merge into each operation under the path
(operation-level entries override per OpenAPI spec semantics);
the import no longer fails with "unbound placeholder" for
shared-param specs
- [ ] Success sweep accepts `"2XX"` (SSE detection + output schema)
and error sweep accepts `"4XX"/"5XX"` (`HTTP_`-class mapping per
the wildcard's implied status range — choose the mapping, e.g.
4XX → the strongest available code, and document it)
- [ ] `webhooks`: import (as Mutations/Webhook-kind ops or a decided
visibility) or reject the key loudly — pick per ADR-066's
single-endpoint adapter philosophy and record the decision
- [ ] The misleading-diagnosis fix: when import fails after skipping
path-item parameters, the error names the actual cause (the
skip-filter whitelist must not hide the parameter key from the
unsupported-features warning)
- [ ] Tests: shared-path-params spec imports correctly (incl.
operation-override precedence); `2XX`-declared SSE imports as
Sub; `5XX`-declared error lands in error schemas; webhooks-only
and mixed docs behave per the decision
- [ ] `cargo test`, `cargo clippy --all-targets -- -D warnings`,
`cargo fmt --check` pass

## Notes
Slice suggestion: (1) path-item parameters + diagnosis fix, (2)
wildcard sweeps, (3) webhooks decision. The wildcard-to-error-status
mapping is the one judgment call worth a line in ADR-066 (e.g. "4XX
wildcards project to their range's first legal HTTP_ code per error
dedup rules"). Sequence after review-002-oai11-ref-memoization (same
file, resolver shape changes first) — or rebase-verify.
