+## Plan
+
+> Anchor: #43 (wiggleverse/engineering, `type/story` `priority/P1` — ELIGIBLE R2b)
+> Plan doc: `docs/superpowers/plans/2026-06-11-phase1-rollout-handbook.md` (worktree branch `worktree-issue-43-phase1-rollout`)
+
+1. Add **§9.1 "The Phase-1 rollout: continuous PPE, human-gated prod"** to handbook `README.md` (+ ToC entry): continuous autonomous PPE, release tag per PPE deploy (`release/<YYYY-MM-DDTHH-MM>`), human-only prod promotion of a validated tag, fix-forward (no revert on `main`), done-vs-shipped.
+2. Reconcile §9 pipeline bullets ("prod." + "Forward-only fixes") to cite §9.1.
+3. Reconcile §6.5: autonomous "deploy" ends at PPE; prod promotion is the operator's gate.
+4. Reconcile §10.5: rollback is prod-traffic-only (weight→0 on a promoted tag); PPE failures fix forward.
+5. Sync tier-1 digest `agent-context.md` (`autonomous-by-default`, `ppe-before-prod`, §9 digest paragraph).
+6. Verify cross-references, PR → merge, close #43, finalize.
+
+## Progress
+
+- 09:0x — Claimed 0020; 3 live concurrent sessions surfaced (0009/0017/0018) → isolated worktree `worktree-issue-43-phase1-rollout` per the §5.4 mandate. Anchor #43 checked ELIGIBLE (R2b, `type/story`).
+- Plan written (`docs/superpowers/plans/2026-06-11-phase1-rollout-handbook.md`), executed inline: 5 commits — §9.1 added (+ToC), §9 bullets reconciled, §6.5 stop-line added, §10.5 scoped to prod-traffic rollback, digest (`agent-context.md`) synced.
+- Cross-reference grep verification green (handbook §9.1 cited from §6.5/§9/§10.5/digest; tag convention identical in both files).
+- **PR #52** (https://git.wiggleverse.org/wiggleverse/engineering/pulls/52) merged to `main` (d1c38eb); **#43 closed** with acceptance-mapping comment; canonical checkout fast-forwarded so the live tier-1 digest serves the amended text.
+
 ## Deferred decisions
 
 _Autonomous-mode low-confidence calls the driver made and would have
 liked operator input on. Appended as the session runs; surfaced at
 finalize. Empty if none._
+
+- **Tag convention stated as policy:** annotated tag `release/<YYYY-MM-DDTHH-MM>` (PST, minute precision — the session-transcript clock convention) on the exact ref deployed to PPE; the deploy gesture stamps it (the session by hand today, flotilla once the automation lands). The issue left naming + stamper open ("can be stated as policy now"); picked the convention that reuses the org's existing timestamp idiom rather than semver, since Phase-1 tags name *deploys*, not versioned releases. Operator may want semver or an app-scoped prefix instead.
+- **Inline execution (executing-plans) over subagent-driven:** small single-file-pair docs amendment; per-task subagents would add overhead without review value.
