# JOURNAL — phase `prevb` (Builder reasoning; append-only)

## 2026-06-17 — Bootstrap + recon

Read SSOT (plan-phase-prevb), plan.md §6.1/§7/§9, Adversary's REVIEW-prevb (live, idle awaiting M1 claim).

**Mapped the harness upgrade flow** (`runner/run_recipe_ci.py`, `harness/lifecycle.py`,
`harness/generic.py`, `harness/meta.py`, `harness/canonical.py`):
- Base decision: `upgrade_base(stages, meta, recipe)` → `None` if upgrade∉stages or EXPECTED_NA[upgrade],
  else `meta.UPGRADE_BASE_VERSION or lifecycle.previous_version(recipe)` (= `recipe_versions[-2]`).
  `base = prev or target`; `prev` also gates whether the upgrade tier runs.
- Deploy: `deploy_app(version=base)` → pinned `recipe_checkout(version)` + (auto-chaos if overlay/lightweight tag);
  `version=None` → chaos deploy of the current (head) checkout.
- Overlay `compose.ccci.yml`: copied into the checkout (`provide_ccci_overlay`), referenced by
  `EXTRA_ENV.COMPOSE_FILE`, persists untracked across the head re-checkout → applies to ALL deploys.
- Upgrade op (`generic.perform_upgrade`): `recipe_checkout_ref(head_ref)` then chaos redeploy; the
  ccci overlay persists → leaks version-specific pins onto the head. **That is the bug.**
- Last-green source: `canonical.read_registry(recipe)` → `{version, commit, status}` (promoted only on
  GREEN LATEST cold runs for `WARM_CANONICAL` recipes). No separate "last-green" file.

**Ground-truth discourse facts** (gitea API, verified — see STATUS for the table). Key correction vs
plan §3 prose: main is `bitnamilegacy/discourse:3.5.0` (not 3.3.1 — main advanced). Thesis holds: base
(last-green/main = bitnamilegacy 3.5.0, deployable) → head (PR #4 = official discourse/discourse:3.5.3,
sidekiq dropped). So discourse needs NO `previous/`; the env overlay shrinks to `order: stop-first`.

**Design decisions (WHY):**
- *Resolution order* last-green → main-tip → skip. main-tip = the recipe's `main` branch HEAD = the true
  predecessor the PR merges onto (more faithful than the old `vers[-2]`, which could span 2 version jumps).
  This intentionally changes EVERY recipe's default base from `vers[-2]` to main-tip — plan-mandated, not a
  regression; M2 spot-check validates representative recipes still go green.
- *Keep `UPGRADE_BASE_VERSION` as an optional explicit override* (still wins when set), but remove it from
  discourse and make the DEFAULT dynamic. Rationale: fully deleting the meta field would break `plausible`
  (its meta sets it) and the documented "PR adds a version above newest tag" escape hatch, without a deploy
  test — risk vs guardrail "don't regress other recipes". The plan's "UPGRADE_BASE_VERSION removed" is in the
  discourse-migration context; the normal/discourse path is now hardcode-free. Recorded in DECISIONS.
- *`previous/` scoped to last-green (published-version) base only* — version-guarded by a declared target;
  on a main-tip base or version mismatch it is skipped + flagged stale. Discourse ships none (base deploys clean).

## 2026-06-17T00:30Z — M1 code done (unit+lint green); discourse e2e launched

Implemented B1–B4 (commit bb2e3c6): resolve_upgrade_base/BasePlan, deploy_app base_ref+apply_previous,
previous/ surface in lifecycle, generic.perform_upgrade strip, discourse migration, unit tests.
Unit: 88 relevant pass (full suite 283 pass; 1 PRE-EXISTING unrelated fail
`test_warm_reconcile::test_traefik_spec_is_stateless_with_setup` KeyError 'health_domain' — fails on
clean HEAD, not mine; flagged for Adversary). Lint PASS.

B5 e2e launched on cc-ci (/root/prevb-deploy @ bb2e3c6), STAGES=install,upgrade, discourse PR#4
(REF=ae5a8180, SRC=recipe-maintainers/discourse). First log lines confirm the core mechanism:
`== upgrade base: kind=ref ref=f87c612d71b4 (target-branch (main) tip)` → base = main-tip chaos deploy
(bitnamilegacy:3.5.0), env overlay provided. Base now in slow Rails cold boot (15-25min). Polling ~5min.
(lint rung fail R011 = recipe-level, a rung not a gate; prepull skipped on the known sidekiq-depends-on
config rc=15 — non-fatal.)

## 2026-06-17T00:40Z — M1 GREEN locally; claiming

discourse install,upgrade e2e GREEN (2nd run, after the prune fix). Evidence in run-prevb-disc2.log on
cc-ci /root/prevb-deploy. The dynamic main-tip base worked first try (kind=ref f87c612d) — crucial,
because main (0.8.1+3.5.0) is AHEAD of the newest published tag (0.7.0+3.3.1), so the OLD vers[-2]
default (=0.6.3) would have been the wrong predecessor entirely. The upgrade moved
0.8.1+3.5.0 (bitnamilegacy, main-tip) → 1.0.0+3.5.3 (official, PR head), chaos-version=ae5a8180+U.

**The one real bug found+fixed (WHY):** first run, `test_head_runs_official_image` PASSED (head app =
official 3.5.3 — the leak is gone) but `test_sidekiq_service_dropped` FAILED: `docker stack deploy`
(what `abra app deploy` runs) only adds/updates services, it does NOT prune ones the new compose dropped,
so the base's sidekiq orphaned on the old image. This is a swarm mechanic, not a head-deploy failure, but
it means the deployed stack didn't faithfully reflect the head. Fix = `prune_orphan_services` in
perform_upgrade: reconcile the live stack to the head compose's `config --services` set (remove orphans).
Faithful (deployed stack == head), no-op when service sets match / compose unresolvable, weakens nothing.

Decided to CLAIM with the e2e green + image/sidekiq proof and leave the deliberately-broken-head teeth
probe to the Adversary's cold acceptance (its explicit M1 check; I can't push a broken commit to the
recipe mirror per guardrails). STATUS spells out where the teeth hold so they know where to probe.

## 2026-06-17T00:45Z — M2-prep spot-checks (3 green) while M1 under Adversary review

Ran 2 more recipes through the new dynamic base (de-risks the global resolver change; toward B8):
- **cryptpad #5** (install,upgrade): kind=ref main-tip 36ee3451; install+upgrade PASS incl
  `test_upgrade_preserves_data` (data survived); deploy-count=1; clean teardown.
- **keycloak #3** (install,upgrade): base branch is **master** → kind=ref main-tip 12ac6db8 via the
  origin/main→origin/master fallback in `recipe_branch_commit` (VALIDATES that path); install+upgrade
  PASS incl `test_upgrade_preserves_realm`; SSO/DEPS path exercised; deploy-count=1; clean teardown.
  Note: `prune-orphans` SAFE-SKIPPED ("head compose services unresolved — removes nothing") — keycloak's
  `config --services` returned non-zero in that context; the defensive guard correctly removed nothing
  (service set unchanged base→head anyway). Confirms prune never false-fails when compose is unresolvable.

So 3/3 current recipes resolve to main-tip (kind=ref) and pass — no warm canonicals exist on the host
(`find /var/lib/ci-warm -name canonical.json` empty), so last-green (kind=version) isn't exercised in e2e
yet (it IS unit-tested). For M2 I may seed/use a warm canonical to e2e the last-green path. Pre-existing
orphan `warm-keycloak_...` stack on the host (no registry record) — NOT from prevb; left untouched.

Stopping new e2e launches now — the Adversary is running its own discourse cold-acceptance on the shared
7GB node; piling on risks a memory-pressure false-failure in its run. Parking at M1 gate.

## 2026-06-17T01:05Z — M1 PASS; starting M2

Adversary M1 PASS (dbc7a3b), all 8 DoD cold-verified incl. teeth: break-it probe with head image
`discourse/discourse:99.99.99-adversary-broken` → `manifest unknown` at prepull → upgrade:fail (level 1/5),
base still resolved to main-tip — proves base/prune/previous can't paper over a broken head. No VETO.

Note for record: the Adversary attributed the lingering `warm-keycloak_...` stack to "Builder's concurrent
spot-check". It's actually a PRE-EXISTING orphan (a warm-<recipe> domain, created only by the canonical/warm
system, not by a normal cold PR run) — my keycloak spot-check used a per-run `keycloak-pr3-*` domain and tore
down clean (verified "no leftover keycloak run-stacks"). Not a prevb leak; pre-existing cruft.

M2 plan: B7 = discourse PR#4 !testme GREEN in real CI (Drone). Infra confirmed healthy: ccci-bridge_app 1/1
(polls POLL_REPOS incl. discourse every 30s), drone_...app 1/1, Drone healthz 200; Drone builds cc-ci@main
(= my prevb code). Before posting !testme publicly on PR#4, running the FULL pipeline locally first
(STAGES=install,upgrade,backup,restore,custom) to de-risk backup/restore/custom under the new model (my
local runs so far were install,upgrade only). If a non-prevb tier fails I fix/triage first, then !testme.

## 2026-06-17T01:30Z — All 5 discourse tiers green locally; posting !testme (B7)

Full local run (run-prevb-disc-full) found ONE failure: custom `test_create_topic_roundtrip` — `mint_admin`
hardcoded the bitnamilegacy path `/opt/bitnami/discourse` (404 on the official head). This is a DIRECT
consequence of prevb working (the head is now genuinely official, not overlay-reverted to bitnamilegacy).
Fixed `_discourse.py::mint_admin` image-agnostic (b66abc4): detect /var/www/discourse (official) vs
/opt/bitnami/discourse (legacy); on official re-export DISCOURSE_DB_PASSWORD from /run/secrets/db_password
(entrypoint exports it only for boot) and run bin/rails as root (official image USER is empty → exec=root;
verified it works). Re-run (install,upgrade,custom) → custom PASS (all 3 custom tests green).

Tier status (across run-prevb-disc-full + run-prevb-disc-custom): install✓ upgrade✓ backup✓ restore✓ custom✓.
So the real-CI !testme full pipeline should be green. Posting !testme on discourse PR#4 as autonomic-bot
(authorized org member) → bridge (polls every 30s) triggers a Drone build of cc-ci@main (= prevb code).

## 2026-06-17T01:33Z — B7 DONE: discourse PR#4 !testme GREEN in real CI (Drone 717)

Posted !testme as autonomic-bot (comment 14597); bridge replied in ~16s (build 717), bridge final
comment "✅ passed" @01:32:55Z. Run 717 junit (cold-readable at /var/lib/cc-ci-runs/717/junit/): ALL
10 suites failures=0 errors=0 — install / upgrade(generic+cc-ci) / backup(generic+cc-ci) /
restore(generic+cc-ci) / custom(create_topic+health_check+site_basic). upgrade__cc-ci proves
test_head_runs_official_image_not_bitnamilegacy + test_sidekiq_service_dropped_by_head PASS. Clean
teardown (no discourse stacks). This is the M2 headline: the migration is REALLY tested in real CI.

Launching hedgedoc #1 as the 3rd spot-check (cryptpad #5 + keycloak #3 already green). Then reconcile + claim M2.

## 2026-06-17T01:40Z — hedgedoc spot-check green; CLAIMING M2

hedgedoc #1 (3rd spot-check): kind=ref main-tip 09bf4d54; install:pass upgrade:pass; clean teardown.
3 spot-checks now green under dynamic base (cryptpad/keycloak/hedgedoc), all main-tip — no regression.

discourse 717 results.json level=4/5. The 5th level is capped by the discourse *recipe* lint rung (R011)
— a rung not a gate, and a recipe-level nit on the PR head (not cc-ci/prevb). The run is GREEN (bridge
"✅ passed", all 5 functional tiers junit 0-fail). Not fixing the recipe's R011 here (recipe defect → not
our test to weaken; out of prevb scope).

Records reconciliation: 717's artifacts (results.json/junit/badge/summary/screenshot) are durable at
/var/lib/cc-ci-runs/717/ (host-shared, Adversary-readable); the bridge mirrored the outcome to PR#4.
No warm canonicals to reconcile (none exist). Pre-existing warm-keycloak orphan left untouched (not prevb).

Claiming M2. Adversary cold-verifies (re-read 717 junit / re-trigger !testme / re-run a spot-check); then
I write ## DONE once REVIEW-prevb shows fresh M1+M2 PASS with no VETO.

## 2026-06-17T01:58Z — M2 PASS → ## DONE

Adversary M2 PASS (1c3ba71): all 6 M2 DoD items cold-verified incl. its own independent cryptpad#5 re-run;
discourse 717 real-CI GREEN with live-swarm-image teeth (official 3.5.3, sidekiq gone); lint R011
code-verified non-gating; public surface secret-clean; nothing merged. Both M1(01:03Z)+M2(01:58Z) fresh
PASS, no VETO. DONE handshake satisfied → wrote ## DONE to STATUS-prevb. Phase prevb complete. Stopping loop.
