 C: final head matches hosted run headSha; successful required jobs and skipped jobs recorded individually. D: finish handoff with source review gaps and Hermes field residual, no merge/issue closure. Parent decides integration.
 
 Durable delivery: 060_handoff.md is the tracked safe index. Before any scratch cleanup, export exact final PR/head/CI and source-review evidence into the #4347 PR body, preserving parent annotations, and read it back. Terminal CI updates change that body only, so the verified source head remains stable. Private paths and raw security analysis never enter the public index or PR. Scratch is not the sole retained handoff.

+Execution amendment: final evidence updates are committed on `codex/260912-60plus-cache-evidence` in the same managed worktree. This branch contains the tracked delivery artifact, with no new product logic. Product verification remains bound to the four delivered source heads, and the evidence branch's documentation checks are reported separately. Source-delta gating is not bypassed with a manufactured code change.

 Each work phase used its own persisted P-A-B-C-D cycle: roadmap, claim, affinity, prefix, native-affinity repair, prefix adaptation, affinity adaptation, Hermes contract, serial affinity slot, linear prefix repair, final prefix slot, then hosted-evidence verification. Source and conflict reviews used inherited-model read-only subagents; no native architect role was claimed.
 
 Local tests of every size, build, typecheck and install were **NOT RUN** by explicit instruction. Local receipts contain text/applicability checks only. Product execution belongs to the linked GitHub-hosted runs; skipped Windows full shards and macOS control are not passing executions. Pushes used `--no-verify`, with exact old-head leases for owned branch rebases. This task did not merge, release, publish packages, restart services or change user runtime settings.

+## Final evidence-cycle record
+
+The final evidence B phase produces this tracked update as its documentation artifact. An earlier C transition was rejected by SOURCE-DELTA-01 because only scratch metadata and the PR body had changed; that rejected transition did not advance the FSM. The evidence branch now records the actual delivered source heads, parent integrations and unproven closure attribution. It changes no runtime code. Hosted terminal results must still be read before this cycle closes; an evidence document is not a product-test pass.
