+
+## 2026-06-17 — Phase bootstrap + sweep start
+
+### Context
+Phase `prevb` completed with DONE at b6f526a. The prevb change introduced:
+- Dynamic upgrade-base resolution: last-green (warm canonical) → main-tip (ref) → skip
+- `previous/` overlay mechanism (base-only, version-guarded)
+- Environmental vs version-specific overlay split
+
+There are NO warm canonical registry records on the server (`/var/lib/ci-warm/` has only
+keycloak/traefik reconciler dirs, no `canonical.json`). So for all recipes, the post-prevb base
+resolution will use **main-tip ref** as the upgrade base (kind=ref), unless:
+- EXPECTED_NA[upgrade] is declared (bluesky-pds → skip)
+- UPGRADE_BASE_VERSION is set (plausible → version 3.0.1+v2.0.0)
+
+This is the key structural difference from pre-prevb: old code used `lifecycle.previous_version(recipe)`
+(the previous published tag), new code uses main-tip commit ref for most recipes.
+
+Three prevb spot-checks already confirmed green with post-prevb code:
+- cryptpad PR#5: kind=ref main-tip 36ee3451; upgrade=pass
+- keycloak PR#3: kind=ref main-tip 12ac6db8; upgrade=pass (prune-orphans safe-skip)
+- hedgedoc PR#1: kind=ref main-tip 09bf4d54; upgrade=pass
+
+Remaining 18 recipes to sweep.
+
+### Sweep strategy
+- Batch ≤3 concurrent Drone builds via !testme on open PRs
+- Create trivial "chore: regall test trigger" PRs for recipes with no open PRs
+- Monitor Drone build numbers, collect results.json levels
+- Compare to baseline table

+
+SSOT: `/srv/cc-ci/cc-ci-plan/plan-phase-regall-recipe-regression.md`.
+State files: this + BACKLOG-regall.md, REVIEW-regall.md (Adversary), JOURNAL-regall.md. DECISIONS.md shared.
+
+## Phase
+Started 2026-06-17. Gates: **M1** (sweep complete + classified), **M2** (regressions fixed + re-verified).
+
+## Current status
+
+Sweep **IN PROGRESS** — batch 1 triggered, awaiting results.
+
+### Pre-prevb baseline (from run records, Jun 12-15 with OLD code)
+
+| recipe | baseline level | upgrade rung | baseline run |
+|---|---|---|---|
+| bluesky-pds | 5 | skip (EXPECTED_NA) | 556 |
+| cryptpad | 5 | pass | 554 |
+| custom-html | 5 | pass | 541 |
+| custom-html-tiny | 5 | pass | 510 |
+| discourse | 4 | pass (prevb M2 fix → run 717) | 717 |
+| drone | 5 | pass | 692 |
+| ghost | 5 | pass | 657 |
+| gitea | 5 | pass | 695 |
+| hedgedoc | 5 | pass | 608 |
+| immich | 5 | pass | 522 |
+| keycloak | 5 | pass | 553 |
+| lasuite-docs | 5 | pass | 523 |
+| lasuite-drive | 5 | pass | 524 |
+| lasuite-meet | 5 | pass | 525 |
+| mailu | 5 | skip (no deployable base) | 526 |
+| matrix-synapse | 5 | pass | 656 |
+| mattermost-lts | 5 | pass | 529 |
+| mumble | 5 | pass | 558 |
+| n8n | 5 | pass | 528 |
+| plausible | 5 | pass | 658 |
+| uptime-kuma | 5 | pass | 531 |
+
+Note: discourse baseline = run 717 (prevb M2, post-prevb code, Jun 17). All others Jun 12-15 (pre-prevb code).
+
+### Post-prevb spot-checks (done during prevb M2, count toward regall)
+
+These were run on Jun 17 with post-prevb code and confirmed GREEN:
+- **cryptpad** PR#5: upgrade=pass (kind=ref main-tip; data-continuity pass) — Adversary-confirmed
+- **keycloak** PR#3: upgrade=pass (kind=ref main-tip via origin/master fallback; realm-continuity pass)
+- **hedgedoc** PR#1: upgrade=pass (kind=ref main-tip)
