+# 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

+## Visual prompt

+> A square self-portrait of a quiet worker-figure of brushed pale metal

+> platform workbench. On the bench rest four stacked sealed brass
+> workplan plates, a small brass admission gate standing open on one
+> side and closed on the other, and one empty circular shelf left
+> honestly vacant. Behind him a single stamped restore seal hangs on
+> the indigo wall. Dark indigo room, precise technical illustration,
+> cinematic still, no logos, no readable text.

+
+## 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.
