Session A audit (read/plan only). Reconciled docs/cc-2.1.x-gap-matrix.md (the
v5.2.0 plan) against HEAD: the entire HIGH-priority false-positive cluster is
already CLOSED in v5.2.0 (settings keys + xhigh, 28 hook events, MCP POSIX/trust,
claude-md HIGH->MEDIUM reframe, DIS/CNF param-aware). The 8 unreleased commits add
incrementally; no active bug or false positive remains unshipped.
Operator GO 2026-06-19: "Release-only, ship-list tom" -> Session B SKIPPED. All
still-open gaps are M-effort enhancements -> defer to v5.4. v5.3.0 = docs +
knowledge + release of the 8 commits already on main.
Output: scope-decision block appended to docs/v5.3.0-release-plan.md (empty
ship-list + verbatim GO + full draft CHANGELOG bullets mapping all 8 commits +
What's New draft + 3 knowledge-backing entries for Session C); reconciliation
block prepended to docs/cc-2.1.x-gap-matrix.md. Version confirmed 5.3.0 (minor,
non-breaking). 9 commits 1576909..HEAD = 8 mapped + 1 excluded (the plan commit).
