Summary

Phase 2 (issue #164) citation-backfill batch 23: CANCEL (request_cancel.c).

Cited 7 of 8 remaining uncited REQ-CANCEL-* requirements against TC18 §11.2.3's three cancellation mechanisms:

  • REQ-CANCEL-003 — clear-all decode validation (§11.2.3.1 Figure 13/Table 11, request_type 0x05)
  • REQ-CANCEL-006 — clear-single decode validation (§11.2.3.3 Figure 15/Table 13, request_type 0x07)
  • REQ-CANCEL-008, 010 — cancellable-window predicate
  • REQ-CANCEL-009, 011 — NOT_FOUND/CANCELED outcome logic
  • REQ-CANCEL-012 — chain-cascade predicate

Left uncited: REQ-CANCEL-001 (strerror() uniqueness) — standing pattern.

A second id-mapping error caught and fixed before any edit ran, same class as batch 22's: REQ-CANCEL-007 was drafted as a target but the pre-flight scan showed it already cited — folded its intended citation into 006.

Verification

  • Purely additive .fusa-reqs.json change; no source/test code touched.
  • Full build: 69/69 targets. Full test suite: 64/64 passed.
  • cfusa check: 0 errors.
  • cfusa trace --req-coverage 100 --sec-tested 100: 100%/100%.
  • .fusa-reqs.json JSON-validated.
  • Citation count: 622/1028 (60.5%) → 629/1028 (61.2%). CANCEL module: 4/12 → 11/12.

Ref: issue #164.

Cited 7/8 remaining uncited REQ-CANCEL-* requirements against TC18
§11.2.3's clear-all/clear-single wire formats, the cancellable-window
predicate, NOT_FOUND/CANCELED outcome logic, and the chain-cascade
predicate. A second id-mapping error (REQ-CANCEL-007, already cited)
caught and fixed by the pre-flight check before any edit ran.

Purely additive; no code or test behavior changed. 1028 requirements
(unchanged count), 100% traced+tested, 0 cfusa check errors.
