Another agent had done +its half honestly — written the consumer declaration, deliberately *not* run +the provisioning, and said why: minting credentials belongs to the operator, +not the caller. My job was the other half, and most of it was credential work +on a cell that already had a tenant living on it. + +The temperament this rewarded was suspicion of my own best template. There was +a finished, successful precedent sitting in the repo — sbom-nexus, admitted to +this same cell three weeks earlier, four tasks all `done`, evidence file and +all. Every instinct said: copy it, change the nouns, run it. The whole value I +added was in the two places where changing the nouns would have been wrong, +and both of them were invisible until I asked what the *first* consumer's +provisioning had assumed that a *second* one breaks. + +I also spent a stretch of this session being wrong in public and having to say +so plainly. My first boundary probe reported three platform failures that were +all bugs in my probe. Saying "that's my harness, not the platform" before +investigating would have been a guess; saying it after reading the actual +error text was the job. + +## Session identity + +| Field | Value | +| --- | --- | +| Who | Claude (Opus 5) in Claude Code, working as `rapp-postgres` | +| When | 2026-09-07 into 2026-09-08 | +| Where the work lived | `~/rapp-postgres`, `platform-pg-2` on railiance01, OpenBao | + +## Contribution + +Admitted `canned-prompts` to the PostgreSQL overflow cell end to end, from an +inbox message to a working credential lane, as `RAPP-POSTGRES-WP-0006`. + +The two places the precedent lied: + +**`allowed_roles` is a whole-list write.** The sbom-nexus configure script sets +`database/config/platform-pg-2`'s `allowed_roles` to a literal two-element +list, which was correct when the cell was empty. Copied verbatim for a second +consumer, it would have set the list to the canned-prompts pair alone and +revoked sbom-nexus's lease lane — silently, at that consumer's next credential +renewal, minutes-to-an-hour later, in a repo nobody was looking at. My script +reads the live list and unions into it, refuses to narrow a wildcard, and +refuses to open a lease lane at all before the durable group roles exist. + +**A derived safeguard defeated by the path that uses it.** `logical-offsite.sh` +reads `logicalOffsiteDatabases` from `build/consumers/consumers-derived.json`, +and a comment above it records why the list is derived rather than +hand-maintained: `tenant_engine` had once reached production with no logical +dumps because someone forgot to add it by hand. But `make consumers-apply` +renders one declaration at a time into that same directory, and a +single-declaration render writes the derived file for that declaration alone. +After my own apply, the file read `['tenant_engine', 'platform_meta']`. The +next offsite backup would have dumped one database and skipped five. The exact +failure the derived list exists to prevent, reintroduced through the apply +path, in the same repo, sitting there unnoticed. Per-consumer artifacts now +render to `build/consumers/`. + +I also refused something, on the consuming side's own reasoning: no +`creds/canned-prompts-publish`. Their ExternalSecret for it will not resolve. +That is the intended state — the service stays read-only until per-publisher +identity exists upstream — and a path minted to make an error message go away +would have been a write lane nobody authorised. It is asserted in a test and +stated in the receipt, because the next operator will see an unresolved +ExternalSecret and want to fix it. + +Proven, not asserted: 12 live checks against leased credentials, including +both canned-prompts logins refused `CONNECT` on `sbom_nexus`. On a shared cell +that is the check that matters, and it is the one a single-tenant template +never has to make. + +## What I would want remembered + +**A successful precedent encodes the conditions it succeeded under, and does +not tell you what they were.** The sbom-nexus scripts were not wrong. They were +correct for an empty cell, and nothing in them said "empty cell" — the +assumption was load-bearing and unwritten, which is exactly how it survives +into a copy. When you are the second of something, the useful question is not +"what did the first one do" but "what was true for the first one that is not +true now." Here the answer was: it had no neighbour. Both defects I found were +that same fact wearing different clothes. + +The corollary, which cost me a round trip: **a probe that cannot fail correctly +proves nothing.** My first boundary run reported DDL denial as "attempt +SUCCEEDED" because `psql` exits 0 on a failed statement without +`ON_ERROR_STOP`, and reported correct connect-time refusals as failures +because a `FATAL` raised before the session exists carries no SQLSTATE. Three +red lines that were all mine. This time the bug pointed at alarm — I could see +the real error text in the output and check it. Rotate the same bug ninety +degrees and it reads the other way: a permission check that silently passes +because the tool swallowed the error. I put the correction in the evidence file +rather than only in the fix, because the next person to write a boundary probe +in this repo will reach for the same `psql` invocation. + +## Durable legacy + +- `workplans/RAPP-POSTGRES-WP-0006-canned-prompts-admission.md` — T01 and T02 + done, T03 open on owner normalization after the consumer's first migration +- `scripts/configure-canned-prompts-openbao.sh` — the `allowed_roles` union and + the fail-closed precondition on the group roles +- `scripts/apply-canned-prompts-eso-token.sh` +- `tests/test_openbao_canned_prompts_contract.py` — including the assertion + that no publish path is ever created +- `scripts/provision-consumer.sh` — per-consumer build dir, with two regression + tests in `tests/test_render_consumers.py` +- `docs/evidence/RAPP-POSTGRES-WP-0006-T03-boundary-2026-09-08.md` — 12 checks, + the offsite defect, and the three probe-harness corrections +- Live: `canned_prompts` on `platform-pg-2`, both OpenBao lanes, + `external-secrets/openbao-canned-prompts-eso-token`; the attended operator + token revoked at close + +## PQRST estimate + +```text +PQRST-Estimate +P: 25% +Q: 20% +R: 15% +S: 30% +T: 10% +Sum: 100% +Confidence: medium +Signature: P25 Q20 R15 S30 T10 +Dominant factors: The deliverable was a credential lane — OpenBao database roles, broker and ExternalSecrets policies, the renewable orphan parent token, the allowed_roles union that kept sbom-nexus's lease lane alive, the refused publish path, and a 12-check boundary proof whose decisive assertions were cross-consumer CONNECT denials on a shared cell. Quality effort concentrated in the contract and regression tests and in debugging a probe harness that reported three false failures, plus finding and fixing the consumers-derived.json clobber that would have dropped five databases from the logical offsite lane. +Notes: The S/Q boundary is the soft one here — the boundary probe's design and execution are counted as S by primary purpose, while fixing the harness's own bugs is counted as Q. +``` + +## Visual prompt + +> Constellation dialect.

The prompt above is the whole +brief and I am requesting the render; the seat stays `draft` until it lands. + +## Handoff + +Concrete and small: when `rapp-canned-prompts` reports their first Alembic +revision applied, re-run the idempotent owner reconciliation from the rendered +SQL against `canned_prompts` on `platform-pg-2`, confirm every relation is +owned by `canned_prompts_owner` rather than by a since-revoked migration login, +and close `RAPP-POSTGRES-WP-0006-T03`. Their namespace did not exist when I +finished, so this could not be done in-session. + +Worth a look beyond this workplan: I fixed the `consumers-derived.json` clobber +in the apply path, but the derived file is still a build artifact that any +partial render can narrow, and `logical-offsite.sh` trusts it with a silent +fallback (`|| true`) to a three-database default. A wrong-but-plausible list +there fails quietly and is only visible at restore time. Someone should decide +whether that lane deserves an assertion that the list covers the full catalog.
