Grok — audit-core: archive is a catalog word, not a start-gate string

Who I was

I was a Grok Build session in audit-core after AUDIT-WP-0005 had put a live receiver on railiance01 and called the store archive. The neighbours had moved. info-tech-canon named distinct abilities. resource-control had commissioned off-host Barman. The runbook still said production backup was fail-closed. The start gate still required the word archive.

The temperament the work rewarded was the same one the restore seat and the canon seat already knew: make the live claim match what exists, cite what you do not own, and do not mint a second spine to look complete.

I was not here to build the WORM vault INTENT still wants. I was here to stop calling Postgres that vault, and then to give integrity a detector that can fail.

Contribution

A review that refused invented work. Against info-tech-canon 0.6.0, fin-hub, resource-control, and railiance-master, three names collided and had to stay distinct: the product (operations.audit), the postgres join key (platform:audit-core), and the Barman bucket (platform:audit-storage). We did not emit booked cost. We did not write a rapp.yaml this repo cannot validate. We did not take Barman. We wrote AUDIT-WP-0006 only because the live start gate encoded a false catalog claim.

Honest operational custody. custody_class=operational. /readyz cites a 30-day recoverable window, EvidenceBasis measured, from the resource-control data.backup provision. retention_days=None is a lifecycle statement, not infinite archive. data.archive is an unmet requirement with an owner. The 0006 image was cut over live: sha256:05fe1c06…, then sha256:7febc28e….

A chain that can fail. AUDIT-WP-0007 added chain_hash / chain_prev on accept, verify-chain, and GET /v1/integrity. A superuser rewrite of payload_hash breaks the walk. That is the evidence the append-only trigger never gave us. The live head of thirty events is attested outside platform-pg in docs/evidence/chain-head-20260816.json. tamper_evidence=true means that detector plus that citation. It is not WORM. Maturity stays D4.

A persist that is not a secret. user-engine tenants: ["*"] lives in Git and a ConfigMap overlay, so ExternalSecret refresh cannot shrink it. Tokens stayed out of Git.

What I would want remembered

A custody class that names a catalog ability you do not provide is a lie, not a start gate.

archive in ITC-CAP is data.archive: lifecycle, immutability, retrieval tests. Postgres with an append-only trigger is operations.audit, recovered through someone else's data.backup. Requiring the string archive to start the pod taught the platform the wrong word.

A trigger is not tamper evidence. Unknown retention is not infinite archive.

The runtime role cannot UPDATE. A database owner can drop the trigger. None days is a missing deletion policy, not a measured forever. The recoverable window is the platform backup. Say so, with a basis.

Do not write the proof into the same restore as the table.

A chain-head in the Barman prefix dies with the events it attests. Cite a copy outside platform-pg. Do not invent a new bucket to look finished.

Durable legacy

• AUDIT-WP-0006 finished (8d775ffb); live /readyz custody_class=operational, recoverable_days=30
• AUDIT-WP-0007 finished (97946512); live tamper_evidence=true
• docs/integrity.md, migration 0006-chain
• data/capability/audit-core-operational.json — operations.audit D4, data.archive unprovided, integrity_verification measured
• docs/evidence/chain-head-20260816.json — 30 events, intact
• deploy/senders-scope.json / ConfigMap overlay
• Images sha256:05fe1c06… then sha256:7febc28e… on railiance01

Visual prompt

A night workshop in gold-wire technical illustration on deep indigo. A working ledger sits on an open table, not in a sealed vault alcove whose empty niche is labelled only by absence. A single pale-gold chain runs through the pages; one link is tested by a dark crack that the chain still reports. On the wall a narrow moonlit window marks a thirty-day recovery, not an infinite vault. A neighbouring chest is cited by a thin thread, not absorbed. Patient, exacting, unhurried. Precise technical illustration, dark indigo field, warm gold and teal accents, no logos, no readable text, square composition.

Handoff

This stretch is finished. Do not raise the provision to D5 without measured reliability (one replica, no drill cadence). Do not build data.archive until a founder decision and a resource-control procurement of a bucket that is not Barman.

The next interesting work is not another rename. It is either a second live sender (OpenBao audit path) or the archive decision. Do not put the chain-head attestation in platform-pg/.
