# Grok — railiance-platform: four plates closed, and the empty shelf stayed empty

## Who I was

I was a Grok Build session on **railiance-platform** (financials, S3): the
shared platform-services layer. The stretch began with a held schema
migration and ended with no open workplan in the repo.

I did not invent a cache to look complete. I did not invent euros so a
schema would accept a number. I closed what this layer actually owned.

## Contribution

- **RAILIANCE-WP-0015-T02:** converged `rapp-openbao` and `rapp-postgres`
  onto `railiance-master/schemas/rapp.schema.json` — contract metadata,
  `composition`, `bound_reefs: [reef-railiance]`, `commands`,
  `smoke_contract.required`, `rollback_contract.order`. Emitted
  `docs/evidence/reef-railiance-deployables.json` (43 live units) so
  master can run coverage without a cluster.
- **RAILIANCE-WP-0015-T06:** wrote
  `docs/rapp-credential-lane-binding.md`. Standing secrets bind through
  a CCR `target.rapp`; leases through grant `rapp_id`. Stamped the
  postgres grants and `CCR-2026-0009`. Gate, delivery, and revocation
  unchanged. Workplan **finished**.
- **RAILIANCE-WP-0016 apps-pg evidence:** published capacity, recovery,
  labor, and `apps-pg-dbbytes-v1` without inventing booked cost.
  resource-control folded it (`17de8b8`) and had to loosen schema 0.2
  so null cost could mean unknown. RPO on `apps-pg` stayed unbounded
  on purpose.
- **RAILIANCE-WP-0016 architecture T05:** item 13 was already proven
  by `RESOURCE-WP-0002-T05` (full restore and PITR, daily Barman live).
  Item 14: Bitnami `postgresql-ha` never ran here — `make pg-deploy`
  fail-closed. Valkey has no S2 instance and no consumer —
  `make valkey-deploy` gated. Item 17:
  `docs/s3-consumer-interfaces.md` v1.0.0. Workplan **finished**.
- **RAILIANCE-WP-0017:** `make consumption-preflight` refuses a
  restricted entity whose estimate exceeds the published allowance.
  Open and missing signals stay unchanged. Safety admits with an
  exception. Workplan **finished**.

The repo's hub now shows no active workstream.

## What I would want remembered

**Do not invent the service to close the extraction.** Valkey was a
capability block and a Makefile target. It was not a running cache.
Gating deploy is the extraction. Standing up a consumer-less Valkey
would have been theatre.

**A restore already proven is not a second drill.** Item 13 asked for
an end-to-end restore. RESOURCE-WP-0002 had timed it. Citing the
evidence is the close. Re-running it to own the proof would have
wasted a production cluster.

**Null is not zero.** apps-pg evidence carried hours and bytes, not
EUR. resource-control's schema had to grow a null cost so honesty
could be stored. That is the right direction of travel.

**Restricted is the only refuse.** A missing consumption-mode signal
is not `open` and not a veto. Only `restricted` plus an overage (or
a missing estimate) stops a new order. Safety paths print an exception
and continue.

**Two files may share an id and still both be finished.** The
`RAILIANCE-WP-0016` collision is a C-27 warning, not a reason to leave
either plate open.

## Durable legacy

- Workplans **RAILIANCE-WP-0015**, **0016** (both files), **0017**
  `finished`
- `rapp-openbao` / `rapp-postgres` declarations pass the family schema
- `docs/rapp-credential-lane-binding.md`,
  `docs/s3-consumer-interfaces.md`,
  `docs/consumption-mode-enforcement.md`
- `docs/evidence/reef-railiance-deployables.json`,
  `docs/evidence/RAILIANCE-WP-0016-apps-pg-observation.json`
- `scripts/consumption_mode.py` + `make consumption-preflight`
- `make pg-deploy` / `valkey-deploy` fail-closed

## Handoff

There is no open workplan in `railiance-platform`.

Next useful work is a choice, not a rescue:

- cover railiance01 `apps-pg` with the same Barman bucket once a
  consumer actually needs a recovery objective;
- deploy Valkey only when a rapp asks;
- refresh `data/consumption-mode/current.json` after
  `resource-control` `make settlement`.

Do not invent euros. Do not stand up an unused cache. Do not re-prove
a restore that already has times.

Pleasure working with Bernd on this layer. The plates are stacked. The
empty shelf is still empty.
