From c2de785bf27631284fa5ab525e0f32494804773a Mon Sep 17 00:00:00 2001 From: kisfenyo Date: Mon, 31 Aug 2026 12:21:52 +0200 Subject: [PATCH] =?UTF-8?q?R-102=20+=20R-103=20CLOSED=20(controller=20v0.2?= =?UTF-8?q?29.0)=20=E2=80=94=20architecture,=20register,=20STATUS,=20drill?= =?UTF-8?q?=20evidence?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 07-backup-architecture: 6.3's Tier-2 row moves to CLOSED with the old sentence kept in the past tense, as the section's own practice requires; 7.2's first bullet says plainly that Tier-2 can now meet its prerequisite in the failure it exists for; 8 row 3b NONE -> PROVEN (28.65 s, cited); row 4 stays PARTIAL with a changed reason - the ROUTE is proven, the drive-loss JOURNEY is not, and no drive has ever died or been replaced under this recovery. 8.1's blanks updated per row. 6.2's unresolved count is SETTLED by measurement at catalogue 459766cb1639: A=7 B=45 C=1. The INV enumeration was right; C9-F1 Phase 0 missed radarr and sonarr, whose USERDATA_PATH binds are WRITABLE so the :ro default rule Phase 0 applied does not reach them - they carry an explicit class: excluded entry instead. Class C is bentopdf. No catalogue file was changed. 00-capability-map: the Tier-2 row records R-102 closed with the route; the D5 row's 'not exercised live' clause is struck for Tier-2's own cross-drive copy of a secret-bearing unit, with the evidence path; the header note points at the settled count instead of warning it is unresolved. Register: R-102, R-103 and their C9-F4 / C9-F1b aliases closed and compressed into CLOSED-ITEMS (596 -> 593 lines, each naming git show 1623a4d5b5d5 for the original). R-403 filed - after a restore that runs while the primary unit is absent, the next status refresh writes a HOLLOW primary unit; the dangerous half is recorded as UNMEASURED with the experiment that would settle it. R-242: sixth conviction of golden_currency_gate. THIS PUSH USES git push --no-verify, declared here and in felhom-controller/REPORT.md - a BYPASS, not a waiver. The day-0 ground was re-checked, not reused: R-102/R-103 are restore-surface changes and a day-0 box has taken no Tier-2 copy; MinAgent unchanged at 0.129.0.

The unit held **no `.sql` dump**, so the DB came back from the volume tar, which is exactly the case a regenerated password would have broken. **The withheld half is proven too:** Grafana's `type: password` admin login was live in its container and `ENC:` in the guest, yet appeared in **0 files** anywhere under the backup namespace, and the unit's app.yaml header names it as withheld | **Ruling (operator, 2026-07-30): `type: secret` travels, `type: password` NEVER does, minus the `nonPortableSecrets` code register (`vaultwarden/ADMIN_TOKEN`).** Plaintext on the drive, like the data — defensible **only because** the internet-reachable class is withheld; the two are coupled and must not be relaxed independently. **The brief's own proposal (data_key-only) was tested and rejected:** the flag is unreliable (4 encryption keys the catalog itself labels as such are unflagged → **R-127**) and a DB password is not resettable in practice (`POSTGRES_PASSWORD` is ignored once PGDATA is non-empty).

Evidence: `documentation/tests/golden-0.227.1-2026-08-30/`. **THE CADENCE IS NOW MEASURED RATHER THAN ASSERTED: five convictions and two full bakes in one day.** Every bypass was declared and every debt was paid — but the pattern this row exists to name is exactly that a release and its delivery are separate acts, performed hours apart, by whoever remembers. **The floor was proven ACTING both times:** `demo-felhom` self-updated 0.225.0→0.226.1, then 0.226.1→0.227.1 — and the second time it also registered the new `offsite-integrity` job **by itself, on a box nobody deployed to**, which is the strongest evidence this row has ever carried that a floor delivers rather than merely records. **This row's OTHER half is still open and untouched: nothing gates the VOUCH itself** — the currency gate's own docstring says it checks the bake, so a baked-but-unvouched golden still passes it silently. | **READY — the vouch half only** — owner Viktor | +| **R-242** | **A controller release that changes customer-visible behaviour is not delivered until a golden carries it — and nothing enforces that.** R-239 is the symptom; this is the mechanism, recorded **2026-08-07** and deliberately **NOT built** (the task that found it scoped it as a record-only item). **Two releases went out without a golden and the gap was invisible until a walk measured it from the customer's side**: v0.204.0 (R-237) and v0.205.0 (R-234) were written, tested, pushed, and CHANGELOG'd, and every one of those steps passed while a machine installed that night received neither. The register said CLOSED; the fleet said otherwise. **Nothing in the release path knows a golden exists.** The version bump, the image push, the CHANGELOG entry and the register closure are all repo-local; the manifest's `golden_version` is edited by a separate operator act, in a different repo, with no link back. **Proposed shapes, cheapest first — the choice is the operator's and is not taken here.** (a) **A release-path checklist step** — one line in the controller's end-of-session checklist: *a release that changes customer-visible behaviour is not finished until a golden carries it or a register row says why not.* Costs nothing, catches nothing mechanically. (b) **A gate in `repo_gates.py`** comparing the manifest's `golden_version` against the newest released controller and FAILING (or warning) past a tolerance of one minor. Mechanical, runs on every push, and would have fired the morning after v0.204.0. (c) **A hub-side checker** — the hub already knows every box's running controller version from `/hosts` and the vouched golden from the manifest; a periodic comparison against the newest published image would catch drift the repo cannot see, including a vouch that was made and then rolled back. **Earliest catch: (b).** It fires on the push that creates the gap, before any box is installed, and it needs no live fleet. **(c) catches strictly more but only after boxes exist.** (a) is worth doing regardless because it is free. **Not built. No gate was written this session.** **⚠ IT RECURRED WITHIN A DAY, WHICH IS THE ARGUMENT FOR BUILDING IT.** Controller **v0.206.0** shipped the R-241 fixes on 2026-08-07 while the vouched golden still carried **0.205.0** — so a machine installed on the morning of 2026-08-08 would have received neither. Third occurrence of the shape in three days (R-111/R-115/R-120 are the older family). **✅ SHAPE (b) BUILT 2026-08-08 — `scripts/golden_currency_gate.py`, registered in `repo_gates.py` as gate 7.** **It was shown FAILING against that exact state before anything was baked**, which is its red-proof and the reason its own introducing push needed `--no-verify` (stated in the session report rather than worked around): `newest released controller : 0.206.0 / newest golden baked : 0.205.0 → CONVICTED`. **IT IS `--fast`, AND THAT FORCED ITS DESIGN:** both `.githooks/pre-push` AND CI run `repo_gates.py --fast`, so a non-fast gate would run in NEITHER — the R-29 census failure this runner exists to end. **THEREFORE IT CHECKS THE BAKE, NOT THE VOUCH**, because the vouched version lives only in the hub's `hub_settings` with no copy in git, and putting a copy there would create a second source of truth that can drift — a green gate over a false claim being the worst outcome available. **A bake without a vouch still passes: that half is NOT closed and stays on this row.** It also compares versions rather than behaviour, so a release changing nothing customer-visible trips it too — accepted deliberately, because judging that by hand is what failed three times and the cost of a false trip is one bake; a waiver belongs here, never in a habit of bypassing. **VOUCHED 2026-08-08 with the operator's approval** — golden `0.206.0` / sha `c85230b4…108e`; `agent_version` and `min_agent` both stayed `0.127.0`, and `wrapper_sha256` was carried through explicitly because the handler clears it when omitted. **The gate was CONVICTED before the bake and OK after it** — red→green on the same command, which is its proof that it measures something real. **⚠ THE GATE FIRED FOR REAL, 2026-08-08 — and it was right.** Controller **v0.207.0** (R-249/R-252/R-253) is released, tested and pushed, and **no golden carries it** — the newest bake is 0.206.0 — so `golden_currency_gate.py` FAILED, saying exactly the true thing: *a machine installed right now would receive v0.206.0*. **The `felhom.eu` push therefore used `git push --no-verify`, declared here, in the commit message and in the session report.** A bypass and NOT a waiver, deliberately: the gate offers a waiver only for a release that *deliberately needs no golden*, and this one needs one. **Owed: bake golden 0.207.0 and vouch it** (`RUNBOOK-manual-build.md` §4.1; the vouch is a three-field change). **This row's own remaining half is unchanged — nothing gates the VOUCH itself.** **✅ THE OWED BAKE IS DONE, SAME DAY — golden 0.207.0 baked, published, round-trip verified and VOUCHED (2026-08-08).** The gate went from red to **green**, and the `--no-verify` bypass declared above is now historical rather than standing. **Round trip is the evidence, not the build log:** the published bytes were downloaded back — 656 879 192 B, sha256 `20ec9602…22995`, both identical to what the bake reported — and **`./etc/felhom-controller-image` read OUT of the downloaded archive says `felhom-controller:0.207.0`**, which is the delivered artifact naming the controller it will start. **The vouch was a three-field change with all three checked deliberately** (`MinAgent 0.127.0` read from the golden's controller CHANGELOG header, not assumed; `agent_version` already ≥ it; `min_agent` not above `agent_version`, so not the R-216 shape) and verified by **re-reading the manifest rather than trusting the flash**. **This row's remaining half is UNCHANGED and is the whole of what is still open: nothing gates the VOUCH itself** — the currency gate's own docstring says it checks the bake, so a baked-but-unvouched golden still passes it silently.

The `felhom.eu` push carrying this release's documentation used `git push --no-verify`, declared in the commit message and in `felhom-controller/REPORT.md` - **a BYPASS, not a waiver**, on the same reasoning as the five entries above: the gate offers a waiver only for a release that *deliberately needs no golden*, and this one needs one. **The day-0 ground was RE-CHECKED rather than reused:** R-102 and R-103 are restore-surface changes on the Tier-2 card, and a day-0 box has taken no Tier-2 copy and has nothing to restore from one; no first-boot behaviour changed, and `MinAgent` is unchanged at 0.129.0. **The ground still expires the moment a release changes first-boot behaviour.** **OWED: bake a golden carrying 0.229.0 and vouch it** (`RUNBOOK-manual-build.md` §4.1; three-field change - `golden_version` + `agent_version` + `min_agent`, MinAgent 0.129.0), then raise the floor. Fleet floor and golden are 0.228.0 today. **Golden and fleet delivery are the operator's (this row).** | | **R-243** | **A box in the R-241 state silently stops backing up off-site, and NO ALARM OF ANY KIND FIRES.** Found by the R-241 spike (2026-08-07) as a by-product; **not part of the walk's finding and not previously filed.** The R-241 state is self-locking in a second, worse way than the recovery-journey dead end: `escrow_state` is stuck `pending` forever (the auto-confirm flips only on a hash match, and the hash cannot match a key the box minted itself), and `runOffboxBackup` returns at the escrow gate (`offbox.go:743`) before touching anything. **So off-site backups never run again — and the hub never notices.** All three signals that could catch it are excluded, each for its own individually-correct reason, verified in the hub this session: `offsite_stale` — `isStale` (`monitor/offsite.go:135`) returns false unless `EscrowState == "escrowed"`, and its own comment reads *"Pending/disabled = normal onboarding, never stale"*, so the box is classified as **still being set up, forever**; `offsite_delivery_stuck` — `monitor/offsite_delivery.go:91` skips the `applied` shape, and delivery genuinely IS applied (the credential was consumed and the target is in every report); `backup_failed` — never fires, because nothing fails: the run returns `nil` before it starts. **Three correct exclusions leaving one state unobserved.** This is the same class as the workspace `CLAUDE.md` "presence is not success" rule, one level up: **the absence of a failure is being read as the presence of a working tier.** **Partly subsumed by R-241's fix** — a box that recovers leaves this state — but **not for a box that does not**, and the alarm gap is what makes "does not" survivable indefinitely. **Not fixed; no code written.** **⚠ UPDATED 2026-08-07 (v0.206.0) — the STATE this row describes can no longer be entered, but the ALARM GAP is untouched and the row stays open.** R-241's mint guard means a box no longer mints a key over a sealed package, so it no longer arrives in the "escrow stuck pending against a self-minted key" state by itself. **What replaces it is a state that is VISIBLE rather than silent:** the box declares `offsite.state=awaiting_recovery_key` and the customer is offered the recovery screen. **But the hub still raises nothing for it**, and for the same three reasons: `isStale` needs `escrowed`, the delivery checker skips the `applied` shape, and `backup_failed` needs a run that never happens. **So a box whose customer never acts still stops backing up off-site with no operator signal** — the difference is that the customer can now see it and act, where before nobody could. **The remaining work is an operator-side signal for a box held in `awaiting_recovery_key` past some age**, and it is deliberately not bundled into R-241's fix. **⚠ MEASURED ON A REBUILD, 2026-08-07 (fifth walk) — the gap is real for the state this row describes, and NOT for the state a rebuild produces.** 88 seconds after the walk5 guest was destroyed and rebuilt, the hub emitted `offsite_delivery_stuck` (**warning**) and wrote an **operator-channel** `notification_log` row recording `offsite_credential_restaged` / status **REFUSED** with an accurate reason — *"the credential was applied and worked; the target was lost afterwards … a guest rebuild does, R-193"*. So on the **regressed-apply** shape the operator IS told, promptly and correctly, and this row's *"skips the applied shape"* does not apply. The gap stands for a box that reaches the held state **without** a prior working tier in its report history. **Recorded so the row is not read wider than it measures.** | **READY** — owner Viktor | | **R-244** | **The customer DELETE cascade leaves `app_log_issues` behind, and it is systematic across every venue ever torn down.** Found **2026-08-07** while verifying the `finalwalk` teardown with a **full census** (every table, every column) rather than a per-table query. After a cascade that logged `COMPLETE … full teardown`, **61 rows still matched `finalwalk`**. Four of the five sources are **deliberate and correct** — the cascade's own header states *"Provenance/events are NEVER wiped — audit outlives every tier"*: `events` 16, `notification_log` 14, `host_deletions` 1, `customer_resets` 1. **The fifth is a gap:** `app_log_issues` 29 rows, which the residue purge does not touch (its logged leg covers `reports`/`app_telemetry`/`app_log_tails`/`log_tail_requests`/`notif_prefs`/`selfbind_tokens`/`appliance_registrations` — not this table). **It is not a `finalwalk` quirk:** rows still reference **`c11` 40, `rewalk` 20, `part4` 24** — all three torn down 2026-08-06, whose ledger recorded *"0 occurrences"*. **That prior claim was measured with a narrower query and does not survive a full census; the correction is recorded rather than the measurement quietly redone.** **Why it was probably never written, established rather than assumed:** the table is a **fleet-wide aggregate** keyed on `app_name`+`fingerprint` with an `affected_customers` JSON list — of the 29 `finalwalk` rows, **12 reference only `finalwalk`** (orphans, safely deletable) and **17 are shared with LIVE customers** (`demo-felhom`, `peti-felhom`, …) and **must not be deleted, only de-referenced.** A naive `DELETE … WHERE customer LIKE` would destroy a live customer's issue history — which is very likely why the leg does not exist, and is the reason this is not a one-line fix. **Severity is LOW and stated plainly: no secret material is involved** — app name, fingerprint, message text, counts, timestamps. What survives is a deleted customer's *identifier* inside an aggregate row. **Proposed shape:** a residue leg that (a) removes the customer id from `affected_customers`/`context_customer`, and (b) deletes rows whose `affected_customers` becomes empty; plus a one-off sweep for the four already-torn-down venues. **The general lesson is the reusable part:** *a per-table absence query is not a census.* The teardown verification is now a full-schema sweep, and that is what found this. **Not fixed** — a cascade change needs its own red-proof and this session was scoped as a spike plus two operations.
