feat(regression): add E2E canary regression suite (tests/regression/)

Seven canaries prove both halves of the server's job: - GREEN: good apps are reported healthy (good-simple + good-significant) - RED: broken apps are caught at intended tier (false-green guard + 4 per-tier) Fixtures: custom-html-bkp-bad (backup tier RED) + custom-html-rst-bad (restore tier RED). All 7 canaries verified on live server (see STATUS-regression.md for artifacts). Not wired to per-commit CI — run on-demand: pytest -m canary tests/regression/ Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

-## Adversary findings
-
-### A-reg-1 [adversary] CLOSED @2026-06-02T01:46Z — relative import fixed, 3 tests collect
-**Filed:** 2026-06-02T01:37Z
-**Severity:** CRITICAL — suite can't run at all until fixed
-
-Cold-run `cc-ci-run -m pytest tests/regression/ --collect-only` on cc-ci confirms:
-```
-ImportError: attempted relative import with no known parent package
-tests/regression/test_canaries.py:18: from .conftest import run_recipe_ci, ...
-```
-No tests collected. 0 canaries can run.
-
-**Root cause:** `test_canaries.py` uses a relative import (`from .conftest import ...`) which
-requires the directory to be a Python package. Without `tests/regression/__init__.py` (and
-`tests/__init__.py`), pytest imports `test_canaries.py` as a top-level module, not a package
-member. Relative imports fail.
-
-**Repro:**
-```bash
-ssh cc-ci
-cd /root/builder-clone
-cc-ci-run -m pytest tests/regression/ --collect-only
-# → ImportError: attempted relative import with no known parent package
-```
-
-**Fix (either approach):**
-1. Add `tests/__init__.py` and `tests/regression/__init__.py` (makes it a real package)
-2. OR replace `from .conftest import ...` with absolute sys.path manipulation (like other test
-   files do, e.g. `sys.path.insert(0, ...); import conftest`)
-
-**Adversary closes:** after re-running `--collect-only` confirms 3+ tests collected, no error.
-
---
-
-### A-reg-3 [adversary] CLOSED @2026-06-02T02:20Z — fixtures fixed; cold-verified correct tier failures
-
-**Resolved:** Builder created separate recipes (`custom-html-bkp-bad`, `custom-html-rst-bad`) with
-correct fixture structure. Cold-verified from cc-ci artifact dirs (no harness re-run needed).
-
-**Evidence:**
- bad-backup-5 (`b6fe99de`, custom-html-bkp-bad): `install=pass, backup=fail` ✓
-  - `test_backup_artifact: pass` (snapshot IS produced)
-  - `test_backup_captures_state: fail` ("MISSING" not "original") ✓ — backup=RED
- bad-restore-3 (`9a73a184e739`, custom-html-rst-bad): `install=pass, backup=pass, restore=fail` ✓
-  - `test_restore_returns_state: fail` ("mutated" not "original") ✓ — restore=RED
-
-### A-reg-3 [adversary] OPEN — CRITICAL: bad-backup and bad-restore fixtures broken (empty compose.yml)
-**Filed:** 2026-06-02T01:58Z
-**Severity:** CRITICAL — both fixtures fail at upgrade instead of their intended tier
-
-Cold-verified by inspecting `regression-bad-backup` and `regression-bad-restore` branches:
-```bash
-ssh cc-ci 'cd /root/.abra/recipes/custom-html && git diff origin/main..origin/regression-bad-backup -- compose.yml'
-```
-Result: compose.yml is completely empty (entire file deleted, leaving only a blank line). Same
-for `regression-bad-restore`.
-
-**Evidence from run artifacts:**
- `regression-bad-backup-1`: `results: install=pass, upgrade=fail, backup=skip`
-  - Expected: `install=pass, upgrade=pass, backup=fail`
-  - Actual: upgrade fails because chaos deploy deploys empty compose → no service → deploy error
- `regression-bad-restore-*`: never ran to completion (same root cause blocks it)
-
-**Impact on regression test assertions:**
-`_assert_red_at_tier` for bad-backup:
- `failing_tier="backup"` → checks `results["backup"]="skip"` → FAIL: "expected 'backup'='fail', got 'skip'"
- Test would FAIL with confusing assertion, not passing as expected
-
-**Fix:** Recreate both fixture branches with correct compose.yml that:
- bad-backup: keeps full valid nginx service, only changes `backupbot.backup.path` label to `/nonexistent-cc-ci-canary-bad`
- bad-restore: keeps full valid nginx service, changes backup scope to capture a subdir that doesn't contain ci-marker.txt (so restore doesn't recover the marker)
-
-The compose.yml should be identical to main EXCEPT for the single label/config change.
-
-**Repro:** `git diff origin/main..origin/regression-bad-backup -- compose.yml` → empty file
-
-**Adversary closes:** after both fixtures are recreated correctly, runs confirm:
- bad-backup: `install=pass, upgrade=pass, backup=fail`
- bad-restore: `install=pass, upgrade=pass, backup=pass, restore=fail` with `test_restore_returns_state` FAIL
-

-
-### A-reg-2 [adversary] CLOSED @2026-06-02T02:20Z — 4 per-tier RED canaries cold-verified
-
-**Resolved:** All 4 per-tier RED canaries added, artifacts cold-verified on cc-ci.
-
-| Canary | Run artifact | failing_tier | passing_before | verdict |
-|--------|-------------|-------------|---------------|---------|
-| bad-install | regression-bad-install-v2 | install=fail ✓ | [] | CORRECT ✓ |
-| bad-upgrade | regression-bad-upgrade-v2 | upgrade=fail ✓ | install=pass ✓ | CORRECT ✓ |
-| bad-backup | regression-bad-backup-5 | backup=fail ✓ | install=pass ✓ | CORRECT ✓ |
-| bad-restore | regression-bad-restore-3 | restore=fail ✓ | install=pass, backup=pass ✓ | CORRECT ✓ |
-
-`@pytest.mark.canary_fast` marker added ✓. 7 tests collect ✓.
-
-**Note:** bad-backup comment in test_canaries.py says "test_backup_artifact fails" but actual
-behavior is test_backup_artifact PASSES and test_backup_captures_state FAILS. Functional result
-(backup=fail) is correct; comment is misleading but non-blocking.
-
-### A-reg-2 [adversary] OPEN — Plan gap: 4 per-tier RED canaries required by updated DoD
-**Filed:** 2026-06-02T01:37Z
-**Severity:** HIGH — DoD#4 unmet; Builder cannot claim DONE without these
-
-Updated plan (commit 7bdeb74) added DoD#4: four per-tier RED canaries (install/upgrade/backup/
-restore on `custom-html-tiny`) that prove the server reports RED at EACH tier. Each must:
- Assert overall verdict RED at the intended tier
- Assert prior tiers PASSED
- Have teeth: wrongly-green tier would FAIL the test
-
-Current suite only has 3 canaries (good-simple, good-significant, bad-false-green). The 4
-per-tier RED canaries are MISSING. This is a mandatory DoD item.
-
-These also require:
- Fixture branches or SHA-pinned commits where custom-html-tiny is broken at exactly one tier
- A `@pytest.mark.canary_fast` sub-marker (plan recommends it for the fast RED subset)
- README update to document the fast subset
-
-**Adversary closes:** after all 4 canaries exist, run, and the Adversary cold-verifies each
-produces RED at the intended tier with prior tiers PASS.

-# JOURNAL — server regression canaries phase (Builder)
-
-**Phase:** server regression canaries
-**Started:** 2026-06-02
-
---
-
-## Step 0 — phase kickoff and design (2026-06-02)
-
-**Context:** Mirror phase (plan-mirror-enroll-all-recipes.md) completed DONE at 2026-06-02T01:16Z.
-Adversary initialized regression phase files in machine-docs/ at commit f202c5a.
-
-**Decision: run regression tests ON cc-ci, not from the orchestrator**
-
-The regression tests call `run_recipe_ci.py` which uses abra/docker/swarm — these only exist on
-cc-ci. The test process runs under `cc-ci-run python -m pytest`, which sets up the right PATH
-(abra, python3, playwright, etc.). The test then invokes `run_recipe_ci.py` as a subprocess using
-`sys.executable` (inherits the same python3 from cc-ci-run).
-
-The README.md documents the `ssh cc-ci "cc-ci-run python -m pytest tests/regression/ -m canary"`
-invocation pattern.
-
-**Canary selection:**
-
-| ID | Recipe | SHA | Rationale |
-|----|--------|-----|-----------|
-| good-simple | custom-html-tiny | 435df8fc (main) | Fast, few deps, quick signal |
-| good-significant | lasuite-docs | 290a8ad7 (main) | Multi-service, exercises real breadth |
-| bad-false-green | custom-html | 71e7326a (v5-stale-docroot) | Already produced RED build #75; pinned fixture |
-
-SHAs confirmed from Gitea API on 2026-06-02.
-
-**Semantic checks ("teeth") design:**
-
-The regression tests assert BOTH exit code AND named tests in results.json stages. This guards
-against two failure modes:
-1. Harness returns wrong exit code (false-green / false-red) → rc assertion catches it
-2. A specific assertion is silently removed/vacuated → named test disappears from stages → semantic check catches it
-
-For custom-html-tiny: `test_serving` (generic install) must appear passing
-For lasuite-docs: `test_serving_and_frontend` (install overlay) must appear passing
-For bad canary: `test_content_type` (custom functional) must appear failing
-
-**File layout:**
- `tests/regression/conftest.py` — run_recipe_ci(), stage_has_passing_test(), stage_has_failing_test()
- `tests/regression/test_canaries.py` — parametrized @pytest.mark.canary test
- `tests/regression/README.md` — cadence policy + how to run + how to add
-
-**Next step:** commit + push, then run good-simple and bad-false-green canaries to get real output.
-lasuite-docs is slow (10-20 min) so will run it last.

-Command: `RECIPE=custom-html REF=71e7326a... SRC=recipe-maintainers/custom-html cc-ci-run runner/run_recipe_ci.py`
-Result: RC=1, custom=FAIL
-Key output:
- `test_content_type_html_and_txt` FAILED: `ccci-89273b0b.txt Content-Type='application/octet-stream'`, expected `text/plain`
- All other tiers (install/upgrade/backup/restore): PASS
- `flags: {clean_teardown: True, no_secret_leak: True}`
- Confirms: regression test `assert rc != 0` will PASS ✓
- Confirms: `stage_has_failing_test(results, "custom", "test_content_type")` will return True ✓
-
-### good-simple run (regression-good-simple-1)
-Command: `RECIPE=custom-html-tiny REF=435df8fc... SRC=recipe-maintainers/custom-html-tiny cc-ci-run runner/run_recipe_ci.py`
-Result: RC=0, install=pass, upgrade=pass, backup/restore/custom=skip
-Key output:
- `test_serving` in install stage: PASSED ✓
- `flags: {clean_teardown: True, no_secret_leak: True}` ✓
- Confirms: all regression assertions for good-simple will PASS ✓
-
-### good-significant run (regression-good-significant-1) [IN PROGRESS]
-Started ~01:35Z. Multi-service stack (lasuite-docs + keycloak dep). Image pull in progress.
-Expected: GREEN (install/upgrade pass, keycloak dep provisioned, SSO tests run).

-**DoD#1 — tests/regression/ committed:**
- `cc-ci-run -m pytest tests/regression/ --collect-only -q` on cc-ci from PR branch: 7 tests collected ✓
- Files present on `regression-canaries` branch: `conftest.py`, `test_canaries.py`, `README.md`, plus `tests/custom-html-bkp-bad/` and `tests/custom-html-rst-bad/` ✓
-
-**DoD#2 — both good canaries GREEN with semantic assertion teeth:**
- `good-simple` (regression-good-simple-1, SHA `435df8fc`): `install=pass, upgrade=pass`, `test_serving` PASS in install stage ✓
-  - Teeth: if `test_serving` removed → `stage_has_passing_test("install","test_serving")` → False → assert fires ✓
- `good-significant` (regression-good-significant-2, SHA `290a8ad7`): `install=pass, upgrade=pass, backup=pass, restore=pass, custom=pass`, `clean_teardown=true`, `no_secret_leak=true` ✓
-  - `test_serving_and_frontend` PASS in install stage ✓
-  - Teeth: if `test_serving_and_frontend` removed → `stage_has_passing_test("install","test_serving_and_frontend")` → False → assert fires ✓
-  - Run 1 had upgrade=fail (convergence race, transient); run 2 fully GREEN. Known plan risk; no action needed unless persistent.
-
-**DoD#3 — bad-false-green catches false-green:**
- `bad-false-green` (regression-bad-canary-1, SHA `71e7326a`): `custom=fail`, `test_content_type_html_and_txt: FAIL` (Content-Type='application/octet-stream') ✓
- Teeth: if harness returns rc=0 → `assert rc != 0` fires → false-green caught ✓
-
-**DoD#4 — 4 per-tier RED canaries (cold-verified from artifacts):**
- `bad-install` (regression-bad-install-v2, SHA `4ae8866`): `install=fail, upgrade=na` ✓ — failing_tier=install, passing_before=[] ✓
- `bad-upgrade` (regression-bad-upgrade-v2, SHA `4ae8866`): `install=pass, upgrade=fail` ✓ — prior tier PASS verified ✓
- `bad-backup` (regression-bad-backup-5, SHA `b6fe99de`, recipe `custom-html-bkp-bad`): `install=pass, backup=fail` ✓ — `test_backup_captures_state` FAIL ✓
- `bad-restore` (regression-bad-restore-3, SHA `9a73a184`, recipe `custom-html-rst-bad`): `install=pass, backup=pass, restore=fail` ✓ — `test_restore_returns_state` FAIL ✓
- All 4: if harness wrongly returned rc=0 → `assert rc != 0` fires ✓; if wrong tier failed → tier check assertion fires ✓
-
-**DoD#5 — README.md:**
- `tests/regression/README.md` present on regression-canaries branch ✓
- Contains: cadence policy ("Do NOT run on every commit"), canary table, per-tier teeth explanation, how to add a canary ✓
-
-**DoD#6 — NOT merged, PR opened for operator review:**
- PR#5: `https://git.autonomic.zone/recipe-maintainers/cc-ci/pulls/5` — state=open, merged=False ✓
- Branch: `regression-canaries` → `main`. 10 files, 704 insertions ✓
- PR body says "Do not merge — loops never merge" ✓
-
-**Observations (non-blocking, not DoD blockers):**
- good-significant run 1's upgrade=fail was a convergence race; transient (run 2 passed without retry). No test weakening, no retry added — consistent with plan policy.
- Semantic stage_pass_checks only explicitly guard install tier for good-significant. Upgrade/backup/restore tooth coverage is via `_assert_green`'s "no tier failed" check. Limitation noted; acceptable per plan DoD requirements.
- A-reg-2 comment in test_canaries.py says "test_backup_artifact fails" for bad-backup; actual behavior is test_backup_artifact passes and test_backup_captures_state fails. Misleading comment, non-blocking.
-
-**Verdict: D-final PASS.** All 7 canaries verified. All 6 DoD items met. Phase is complete pending operator review of PR#5. No vetoes.

-
-### D-initial update @2026-06-02T01:46Z — A-reg-1 CLOSED; A-reg-2 still open
-
-**A-reg-1 RESOLVED.** Cold-verify after fix:
-```
-ssh cc-ci && cd /root/builder-clone && git pull --rebase
-cc-ci-run -m pytest tests/regression/ --collect-only
-```
-Output: `collected 3 items` — `test_canary[good-simple]`, `test_canary[good-significant]`, `test_canary[bad-false-green]`. No errors.
-
-**Canary artifacts cold-verified from cc-ci artifact dirs:**
-
-`good-simple (custom-html-tiny)` — `/var/lib/cc-ci-runs/regression-good-simple-1/results.json`:
- `results: install=pass, upgrade=pass, backup=skip, restore=skip, custom=skip` ✓
- `flags: clean_teardown=true, no_secret_leak=true` ✓
- `install/test_serving`: PASS ✓ (stage_has_passing_test confirms teeth present)
-
-`bad-false-green (custom-html v5-stale-docroot)` — `/var/lib/cc-ci-runs/regression-bad-canary-1/results.json`:
- `results: install=pass, upgrade=pass, backup=pass, restore=pass, custom=FAIL` ✓
- `flags: clean_teardown=true, no_secret_leak=true` ✓
- `custom/test_content_type_html_and_txt`: FAIL with `Content-Type='application/octet-stream'` ✓
- `rc` would be non-zero (any(v=="fail")) ✓ → regression test `assert rc != 0` PASSES
-
-`good-significant (lasuite-docs)` — upgrade FAILED in Builder's run:
- `results: install=PASS, upgrade=FAIL` — `test_upgrade_reconverges` → convergence race
- This is the known WOPI/upgrade convergence risk from the plan (§ Risks). Builder is re-running.
- OBSERVATION (non-blocking now): if consistently flaky, add bounded retries to readiness probe per
-  plan policy ("bounded retries on readiness only, never on correctness assertion"). Will watch.
-
-**A-reg-2 partially addressed** — 4 per-tier RED canary tests added to suite, 7 tests collect.
-But bad-backup and bad-restore FIXTURES are broken (see A-reg-3). A-reg-2 cannot close until
-all 4 canaries actually produce the expected results.
-
---
-
-### D-initial-2 update @2026-06-02T02:00Z — A-reg-3 filed; bad-backup/bad-restore fixtures broken
-
-4 per-tier RED canary tests now in suite (7 tests collect via cold --collect-only). SHAs verified:
- `4ae8866100563204` (custom-html-tiny, bad image) ✓ — bad-install + bad-upgrade fixture
- `e1e3c5fc5e2bd414` (custom-html, bad-backup) — SHA exists BUT compose.yml is empty (A-reg-3)
- `5a481cc1f6b2a462` (custom-html, bad-restore) — SHA exists BUT compose.yml is empty (A-reg-3)
-
-**Cold-verified canary run results:**
-
-bad-install (regression-bad-install-v2): `install=fail, upgrade=na` ✓ — install tier fails as intended
-bad-upgrade (regression-bad-upgrade-v2): `install=pass, upgrade=fail, custom=skip` ✓ — upgrade tier fails as intended
-bad-backup (regression-bad-backup-1): `install=pass, upgrade=fail, backup=skip` ✗ — WRONG TIER
-
-Root cause A-reg-3: `regression-bad-backup` branch has empty compose.yml (whole file deleted, not
-just backup path changed). Empty compose → chaos upgrade deploy fails → upgrade=fail, backup never
-runs. Same issue for `regression-bad-restore` (same empty compose.yml diff).
-
-**`_assert_red_at_tier` for bad-backup would FAIL** with `expected 'backup'='fail', got 'skip'` —
-proving the fixture is broken, not the test.
-
-**What still needs fixing before final gate:**
-1. ~~A-reg-3~~ CLOSED — fixtures fixed and cold-verified ✓
-2. ~~A-reg-2~~ CLOSED — all 4 per-tier RED canaries present and verified ✓
-3. **good-significant**: still needs successful re-run (upgrade flakiness unresolved)
-4. **Open PR** (DoD#6): not yet opened

-
-### Comprehensive canary verification @2026-06-02T02:20Z
-
-All 6 of 7 canaries cold-verified from cc-ci artifact dirs (fresh SSH shell, no cached state):
-
-**GREEN canaries:**
- `good-simple` (regression-good-simple-1, SHA `435df8fc`): `install=pass, upgrade=pass, backup/restore/custom=skip`, `clean_teardown=true`, `no_secret_leak=true`, `test_serving: pass` ✓
- `good-significant` (regression-good-significant-1, SHA `290a8ad7`): PENDING — upgrade FAIL (convergence race). Needs re-run to confirm transient.
-
-**Custom-assertion RED canary:**
- `bad-false-green` (regression-bad-canary-1, SHA `71e7326a`): `install/upgrade/backup/restore=pass, custom=fail`, `test_content_type_html_and_txt: FAIL` (Content-Type='application/octet-stream') ✓
-
-**Per-tier RED canaries (all cold-verified from artifact dirs):**
- `bad-install` (regression-bad-install-v2, SHA `4ae8866`): `install=fail, upgrade=na` ✓ — failing_tier=install, no prior tier checked
- `bad-upgrade` (regression-bad-upgrade-v2, SHA `4ae8866`): `install=pass, upgrade=fail` ✓ — install=pass before failing
- `bad-backup` (regression-bad-backup-5, SHA `b6fe99de`, recipe `custom-html-bkp-bad`): `install=pass, backup=fail` ✓ — test_backup_captures_state FAIL
- `bad-restore` (regression-bad-restore-3, SHA `9a73a184`, recipe `custom-html-rst-bad`): `install=pass, backup=pass, restore=fail` ✓ — test_restore_returns_state FAIL
-
-**Teeth verification:**
- good-simple: if test_serving removed → stage_has_passing_test("install","test_serving") returns False → regression test FAILS ✓
- bad-false-green: if harness returns rc=0 → assert rc!=0 FAILS → false-green caught ✓  
- bad-install: if harness returns rc=0 for bad image → assert rc!=0 FAILS ✓
- bad-upgrade: if upgrade wrongly passes → tier_results["upgrade"]="pass"≠"fail" → assert FAILS ✓
- bad-backup: if backup wrongly passes → rc=0 → assert rc!=0 FAILS ✓
- bad-restore: if restore wrongly passes → tier_results["restore"]!="fail" → assert FAILS ✓; if backup wrongly fails → tier_results["backup"]!="pass" → assert FAILS ✓
-
-**DoD status:**
- DoD#1 (tests/regression/ committed): ✓
- DoD#2 (good canaries GREEN with semantic assertions): good-simple ✓; good-significant PENDING re-run
- DoD#3 (bad-false-green catches false-green): ✓ verified
- DoD#4 (4 per-tier RED canaries): ✓ all 4 verified
- DoD#5 (README.md): ✓ present with cadence, canaries, how to add
- DoD#6 (PR open for operator review): NOT YET
-
-**Remaining blockers before final PASS:**
-1. good-significant must pass (or flakiness addressed with bounded retries on readiness)
-2. PR must be opened (DoD#6)

-
-### D-initial: FAIL @2026-06-02T01:38Z — suite won't collect (A-reg-1); plan gap (A-reg-2)
-
-Builder claimed: test suite written, initial gate; canaries in-flight.
-
-**Cold verification result: FAIL — two blocking issues.**
-
-**A-reg-1 (CRITICAL): Relative import fails, 0 tests collected.**
-```
-ssh cc-ci && cd /root/builder-clone
-cc-ci-run -m pytest tests/regression/ --collect-only
-```
-Output (cold, fresh shell):
-```
-collected 0 items / 1 error
-ImportError: attempted relative import with no known parent package
-tests/regression/test_canaries.py:18: from .conftest import run_recipe_ci, ...
-!!!!!!!!!!!!!!!!! Interrupted: 1 error during collection !!!!!!!!!!!!!!!!!!!!!
-```
-Root cause: `tests/regression/__init__.py` and `tests/__init__.py` missing. Fix: add them or
-use absolute imports (as other test files in this repo do).
-
-**A-reg-2 (HIGH): Plan updated (commit 7bdeb74) — 4 per-tier RED canaries now mandatory (DoD#4).**
-Updated plan requires RED canaries for install/upgrade/backup/restore tiers on custom-html-tiny,
-each asserting RED at the intended tier with prior tiers PASS. Current suite: 3 canaries only
-(2 good + 1 bad-custom-assertion). All four are MISSING. Cannot claim DONE without them.
-
-**Other code quality observations (not blocking):**
- Canary SHAs all verified present on Gitea ✓
-  - custom-html-tiny: `435df8fc98ef7598` ✓ (main 2026-06-02 merge commit)
-  - lasuite-docs: `290a8ad72d06232f` ✓ (v0.3.3+v5.1.0 merge)
-  - custom-html v5-stale-docroot: `71e7326a99bbb690` ✓ (confirmed RED via build #81)
- `CCCI_RUN_ID` and `CCCI_RUNS_DIR` correctly picked up by `results.py` ✓
- `_assert_red` / `_assert_green` logic sound ✓
- README cadence policy complete ✓
-
-**Verdict: FAIL. Standing issues: A-reg-1 (critical), A-reg-2 (high). Builder must fix both
-before re-claiming this gate.**

-## Pre-orientation findings @01:17Z
-
-**Known-bad fixture confirmed present and working:**
- Branch: `recipe-maintainers/custom-html:v5-stale-docroot` (SHA `71e7326a99bb`)
- Build #81 (run 3h ago): confirmed RED — `custom` stage FAIL; specifically:
-  - `test_content_type_html_and_txt`: FAIL — `ccci-e0d6e804.txt Content-Type='application/octet-stream'`, expected `text/plain`
-  - All other tiers (install/upgrade/backup/restore): PASS
-  - `clean_teardown=true`, `no_secret_leak=true`
- **Implication for regression suite DoD#3**: the known-bad canary correctly produces RED;
-  the regression test must assert this outcome AND must be shown to fail if the server returns
-  green for it (false-green detection).
-
-**Good canaries:**
- `custom-html-tiny`: build #45 GREEN (SHA `4bd8416a209f`, 21h ago) — simple, fast
- `lasuite-docs`: multi-service stack with DEPS=["keycloak"], DEPLOY_TIMEOUT=900s — test exists at tests/lasuite-docs/
-
-**Infrastructure state:**
- Bridge (`ccci-bridge_app`): running, polling 20 repos every 30s ✓
- Drone exec runner: running ✓
- Dashboard: serving at ci.commoninternet.net ✓
- Builder hasn't started regression phase: no STATUS-regression.md yet
-
-**Notes:**
- Mirror phase (plan-mirror-enroll-all-recipes.md) completed DONE at 2026-06-02T01:16Z.
- This phase starts fresh: no STATUS-regression.md or tests/regression/ yet.
- Watching for Builder to create STATUS-regression.md and begin work.

-Proves the deployed static-web-server is *actually serving files from its `content` volume* with real
-file-server semantics, not merely returning 200 from a Traefik fallback or a generic stub:
-
-  1. exact-byte round-trip — write a uniquely-named file with random content into the served volume,
-     fetch it over HTTPS, and assert the bytes come back verbatim. Non-vacuous: the content is random
-     per run, so only a server that reads this file off the volume can pass.
-  2. real 404 — a random non-existent path returns 404, proving directory/file semantics (a
-     200-everything stub or mis-routed host would not 404).
-
-The recipe's image (joseluisq/static-web-server) is shell-less (scratch-based) and its content volume
-is seeded via the install_steps.sh host-mountpoint mechanism — so this test writes its probe file the
-same way (resolve the swarm volume's mountpoint with `docker volume inspect`, write directly) rather
-than `docker exec`-ing in a container that has no shell.
-
-Runs in the custom tier against the shared post-install deployment (the `live_app` fixture is its
-per-run domain). Mirrors install_steps.sh: the app's content volume is named `<stack>_content`, where
-`stack` is the domain with dots replaced by underscores; HTTP_SUBDIR is empty, so the volume root is
-served at `/`.
