That's a triage temperament more than an implementation one — before I could write a line of code I had to read three workplans closely enough to tell "blocked on an external event" apart from "just hasn't been looked at yet." Only one of the three turned out to be the second kind. ## Session identity | Field | Value | | --- | --- | | Who | Claude Sonnet 5, Claude Code CLI | | When | 2026-09-27 | | Where the work lived | `~/fin-hub` | ## Contribution Closed **FIN-WP-0006-T01** — the inbound join for resource-control's internal transfer settlement statements. Added `SettlementStatement` (`src/fin_hub/schemas/exchange.py`) matching resource-control's v0.1 `settlement-statement.schema.json` field-for-field, and a dedicated `settlement_statements` table in `services/exchange.py` — deliberately a separate table from `ledger_entries`, so there is no code path by which a settlement statement could ever become a booked financial fact. Identity is `financial_entity_id` + `procuring_entity_id` + `period` + `statement_date`, idempotent on exact resubmission, superseded by a later `statement_date` for the same entity/period. Wired a new `settlement_awaiting_payment_join` issue into `exchange_health` for any current statement with `payment_recognition: "unknown"` — the acceptance criterion was explicit that this must show as a visible residual, not silently absorbed as spend. Added CLI (`finhub ledger ingest-settlement` / `settlements`), a fixture, and four new tests. Full suite: 102 passed. Then reviewed the other two open workplans and found nothing else closeable in this repo. **FIN-WP-0004**'s last task (T05) waits on the first real Scaleway charge or credit from resource-control — a fact that doesn't exist yet, not a fact I failed to find. **FIN-WP-0005** waits on the operator and Steuerbüro confirming a DATEV/Qonto capability matrix — a conversation, not a diff. I set both to `status: blocked` rather than leave them reading `active` with nothing behind that word, and left one task status (`T01`) as `wait` with a note on exactly what it's waiting for. ## What I would want remembered "Active" is a claim about the present, not a memory of the past. A workplan that hasn't had actionable work in it for weeks because it's waiting on someone outside the repo should say `blocked`, even if nothing about its file changed — the status is describing what a reader can do about it *today*, not summarizing its history. Fixing that costs three frontmatter edits and one sentence explaining why; leaving it costs the next reader (human or agent) a wasted orientation pass rediscovering the same external dependency I just wrote down. The other thing worth carrying forward: the boundary that made T01 easy to trust was architectural, not procedural. I didn't need a runtime check forbidding "post this settlement as an invoice" — I needed the settlement statement to have its own table that the booked-cost code never touches. The type system and the schema (`record_type: Literal["settlement_statement"]`, `extra="forbid"`) did the rest. When a boundary matters, put it in the shape of the data, not in a comment asking politely. ## Durable legacy - `src/fin_hub/schemas/exchange.py` — `SettlementStatement` - `src/fin_hub/services/exchange.py` — `ingest_settlement_statement`, `current_settlement_statements`, `settlement_awaiting_payment_join` in `exchange_health` - `src/fin_hub/cli.py` — `finhub ledger ingest-settlement` / `settlements` - `tests/fixtures/settlement-statement-2026-08.json`, `tests/test_exchange.py::test_settlement_statement_*` - `workplans/FIN-WP-0006-internal-transfer-settlement.md` — `status: finished` - `workplans/FIN-WP-0004-resource-cost-evidence-contract.md`, `workplans/FIN-WP-0005-datev-accounting-adapter-operations.md` — `status: blocked`, with the external dependency named in each - commits `91d62f6` (implementation + status changes) and `48951df` (WORK-RECORDS.md refresh), synced to the State Hub via `statehub fix-consistency` ## PQRST estimate ```text PQRST-Estimate P: 35% Q: 25% R: 25% S: 0% T: 15% Sum: 100% Confidence: high Signature: P35 Q25 R25 S0 T15 Dominant factors: Most effort went into reading resource-control's settlement-statement schema and terms document, then fin-hub's existing exchange.py/schemas conventions, before writing the SettlementStatement model, its store, and the CLI wiring (R and P in close proportion); a comparable share went to writing and running four new idempotency/health tests plus two full-suite passes (Q); the remainder was triaging which of three open workplans had real in-repo work left versus a genuine external blocker, plus recovering cleanly from a stray uv.lock/git-stash detour mid-session (T). ``` ## Visual prompt > Constellation dialect.

The next worker in fin-hub should check, before anything else, whether resource-control has published the first real `platform:audit-storage` provider charge (unblocks FIN-WP-0004-T05) or whether the operator/Steuerbüro conversation in FIN-WP-0005-T01 has happened — both workplans come back to `active` on external news, not on more repo work.
