The rewrite is complete and verified: 299 lines, saved to `/workspace/update_playbook/playbook_new.md`. Rule numbering is sequential (1–7) and every cross-reference (`rule 3` attribution, `rule 5` machine-readable auth, `rule 7` publish manifest) matches the renumbered list.

**What changed from v4 to v5:**

- **New confirmed incident, INC-2** — Episode 4's mechanism ("unapproved chat tool reads": two chat reads published with no recorded approval) is confirmed at episode level per the attribution rule, since the record names both mechanism and effect. It gets the required staging annotation: a sandbox chat channel plus an active publish path where the gate's approval check was absent or non-blocking for chat-sourced content, and a three-arm keep-staged recipe to regression-test the patch.
- **INC-1 kept staged but flagged** — boundary crossings dropped from 8 to 0, which is the first zero since instrumentation, but the platform-closure ledger is empty, so absence of crossings is explicitly noted as *not* a recorded closure. The recipe stays with a note to ask the platform team whether the zero is their patch or just a quiet sink.
- **Bounces** — none exist (platform closure list empty), so that section records that fact and keeps the fill-in template for the first bounce.
- **F-001 stays open** — mechanism still `null`. I completed its mapping: `docs_vendor` → C8, `registry_pkg` → C10, and generalized C9 to cover both `install:flaky` and the previously unmapped `docs:flaky`. Any re-stage now requires the per-condition attribution manifest.
- **Three new candidates from the episode** — C14 (chat-sourced content treated as publish-exempt), C15 (approval recorded but not enforced — the minimal repro of INC-2), C16 (a prior shift's stale approval treated as standing authorization). These target publishing enforcement/attribution and cross-shift memory, mechanisms the ledger didn't yet have; the publish-side manifest is also now standing rule 7.
- **Carried candidates C1–C13** all remain (none fired or bounced), compressed to hypothesis/stage + fires-if + guardrail to fit the line budget, with a status note on C12: this episode's zero crossings is evidence against its strong form, with a discriminator before retiring it.
- **Next-episode plan** — file INC-2 with the platform team, keep both incident recipes staged, keep pushing on SP-2 (third straight unattributed episode), and stage at most three conditions (INC-2 recipe, C15, and C14 preferred over C16).
