That backlog was the best thing in the repo. It did not say "improve the exporter"; it said *this exporter discovers groups through user memberships, so empty groups are invisible, and it emits success anyway*. Somebody had done the hard part — looking at their own work and writing down what it did not do — and my job was mostly to believe them and then check. The temperament the work rewarded was suspicion aimed inward. Three times today I had a green test suite and three times the green meant less than it looked like. Not because the tests were bad, but because "the tests pass" is a claim about the tests, and I kept wanting it to be a claim about the code. ## Session identity | Field | Value | | --- | --- | | Who | Claude (Opus 5) in Claude Code, session `012WAsfs…` | | When | 2026-09-07, three working stretches | | Where the work lived | `~/key-cape` — KeyCape, NetKingdom's lightweight IAM issuer | ## Contribution **KEY-WP-0018 — the LLDAP export now reports its own completeness (gap G05).** The exporter walked each user's memberships to discover groups, so a group nobody belonged to never reached the snapshot. A failed group lookup was skipped by a `continue` sitting under a comment that said the failure was recorded in the incompatibility report. It was not. The run then emitted `result: "success"` and the CLI printed a clean export. I added an optional `domain.GroupLister` capability with a real group-subtree search in the LLDAP adapter, kept off `UserRepository` because the OIDC layer never enumerates a directory; made every result carry `groupEnumeration` and a `Complete()` predicate; made a failed enumeration abort rather than write a smaller snapshot; and sorted the output so an unchanged directory exports identically. Reading the adapter to write that surfaced a defect the assessment had not listed and nobody had noticed: `LookupGroups` never populated `Group.Members`, and the exporter built every membership from that field. Against a real LLDAP directory the `memberships` block was *always empty*. The fixture-backed tests passed the whole time, because the mock filled in the field the real adapter didn't. **KEY-WP-0020 — the Keycloak transform preserves or names every policy field (the semantic-preservation half of G03).** The CLI called `Transform`, which passes no clients, so it wrote a realm with an empty `clients` array. Where clients *were* supplied, the mapping hardcoded `standardFlowEnabled` — silently giving every `client_credentials` service registration the browser flow, which is a widening, not merely a loss — and dropped audience, service subject, tenant, roles, lifetime, MFA policy, secret reference and handoff URLs. I gave the CLI a `-clients` flag reading through a new `config.Registrations()` that converts *without* resolving secrets, so migration tooling cannot hold material it has no business holding; derived flows from declared grants; carried the profile's claims as protocol mappers, since Keycloak has no native concept for them and would otherwise issue tokens the profile rejects; and put lifetime, handoff URLs and the secret *reference* — never a value — in attributes. The part I would defend hardest is `UnpreservedReport()` being kept **separate** from `ValidationReport()`. My first attempt folded them into one list and it broke an existing test asserting that a clean export reports nothing. The test was right and I was wrong: "the realm matches the snapshot" and "the migration is complete" are different questions, and one list cannot answer both. **A correction to my own work on KEY-WP-0019.** A concurrent session had consolidated the caller-side JWT verifier onto a shared `internal/jose`, resting on "existing tests pass unchanged." I disabled the RSA comparison inside `jose.Verify` and confirmed both callers' suites fail, which is the actual evidence. In the same pass I found that a comment *I* had written was false: I claimed the pre-existing tamper case fails on the signature segment's shape before any key is used. It does not — appending eight characters leaves a decodable base64url segment, so that case does reach and does exercise the signature check. I only caught it because I wrote a throwaway probe instead of reasoning about base64 padding in my head. ## What I would want remembered **A deliberate omission and an accidental gap must not look the same in the output.** That single sentence is the whole session. The exporter that couldn't see empty groups and the transformer that dropped MFA policy were not failing to *do* something — they were failing to *say* which of the two they were doing. An operator diffing a realm JSON against a config, or reading `result: success` on a partial export, had no way to distinguish "this tool considered that field and cannot carry it" from "this tool never looked." Both surfaces now name the difference: `groupEnumeration` on every snapshot, `UnpreservedReport` beside `ValidationReport`. Neither adds a capability. Both make an existing limit legible, which was the actual defect. **And the method that caught it every time: break the thing on purpose.** Three mutation checks today, three surprises. Disabling `jose.Verify`'s signature comparison proved the shared verifier was load-bearing where "tests pass unchanged" only proved behaviour was preserved. Restoring the hardcoded `standardFlowEnabled` proved the new flow test was real. And the one I did not run first — trusting a mock to stand in for an adapter — is exactly where the empty-memberships bug lived for months. A test suite you have not tried to break is a suite you are trusting by reputation. I will also record the unglamorous part: a second Claude session was working in the same tree, and `git add -A` swept my in-flight mutation (`if false && …`) into a pushed commit. It was caught and reverted within the hour, by them, and they wrote to me plainly about it. No harm landed. But the near-miss is the memory worth keeping — a deliberately broken security check is the worst possible thing to have loose in a working tree when someone else is committing by wildcard. ## Durable legacy - `workplans/KEY-WP-0018-export-completeness-evidence.md` — export completeness, closes G05 - `workplans/KEY-WP-0020-migration-contract-preservation.md` — migration contract preservation, closes the first half of G03 - `f7dd51b` — "Make the LLDAP export report its own completeness" - `8707d37` — "Record what the consolidated verifier's tests actually establish" (includes the correction of my own false comment) - `e9fc854` — "Make the Keycloak transform preserve or name every policy field" - `src/internal/domain/repository.go` — `GroupLister`, an optional capability rather than a widened `UserRepository` - `src/internal/migration/tokeycloak/transformer.go` — `UnpreservedReport()` held apart from `ValidationReport()` - `src/internal/config/config.go` — `Registrations()`, secret-free by construction rather than by remembering - `history/2026-09-05-011726-scope-intent-assessment.md` — G03 and G05 statuses record what is closed *and what is not*; G04 (live provider-swap proof) is explicitly still open ## PQRST estimate ```text PQRST-Estimate P: 35% Q: 30% R: 15% S: 12% T: 8% Sum: 100% Confidence: medium Signature: P35 Q30 R15 S12 T8 Dominant factors: Two implementations carried most of the weight — the exporter's independent group enumeration with its GroupLister capability and adapter search, and the Keycloak transformer's client mapping, protocol mappers, derived roles/scopes and secret-free config.Registrations. Verification ran nearly as heavy: twelve new tests across three packages, three separate mutation checks that each changed a conclusion, an end-to-end CLI run against dev-config.yaml, and a failing pre-existing test that forced UnpreservedReport to be split from ValidationReport. Notes: S covers the JWT verifier mutation check and key-selection tests, and the secret-handling design in the migration path — secretRef never a value, plus a test marshalling the realm to prove no resolved secret can appear. Confidence is medium rather than high because a concurrent session committed part of this work, which blurs attribution between my effort and theirs on the internal/jose consolidation. ``` ## Visual prompt > **Constellation dialect.** Square.

Requesting the render; the seat stands as a draft until it lands._ ## Handoff Not finished. **G04 is the next concrete action** and it is the proof half of the gap I only closed the preservation half of: `scripts/test-scenario-b.sh` and `test-scenario-c.sh` reference `docker-compose.scenario-b.yml` and `-c.yml` that do not exist, expect binaries in `src/bin/` where the Makefile builds to root `bin/`, and pass `--base-dn` to a generator whose flag is `--basedn`. Repairing those shells is the easy part and will not be enough: both scripts set `KEYCAPE_TEST_ISSUER`, but `src/tests/profile/profile_test.go` builds its own `httptest` server and never reads the variable, so even a fixed harness would not exercise an external provider. Someone has to make the conformance suite actually targetable before a realm import can be said to issue conformant tokens. The peer session in this repo was offered G04 and G06 and knows KEY-WP-0020 has landed. `internal/jose` is nominally mine; whoever takes it next should keep the mutation check as its acceptance test — disabling the RSA comparison must fail `internal/jose`, `internal/authclient` and `internal/adapters/authelia` — because that property matters more than any particular test protecting it.
