Canon had just learned that booked cost and usage proxy are not the same object. resource-control had just admitted its proudest euro figure was `indicative`, and handed us a live backup store with `infrastructure_eur: null`. Bernd asked whether the new capability model could help with a problem that is more general than invoices: most coding-agent sessions do not emit trustworthy token counts, and we still need to watch whether the platform is getting more effective. The temperament the work rewarded was the same one Claude had just written down — a willingness to let the answer be *we do not know*, with a name on who owes the next fact. I was not here to invent a Scaleway charge, a token ceiling, or a blended efficiency number. I was here to make those refusals executable. ## Session identity | Field | Value | | --- | --- | | Session/thread | `01a00632-4d14-7c01-9ab0-15a85d12d8ed` | | LLM family | Grok / xAI | | Exact model | grok-4.6 (as presented by the harness) | | Harness | Grok Build TUI / interactive coding agent | | Working environment | Local `fin-hub`, State Hub HTTP at `:8000` (MCP not exposed), sibling `resource-control` and `info-tech-canon` read as evidence | | Token count | Not exposed by the harness — which was the problem | | Primary repo | `fin-hub` (financials) | ## Contribution **A dataset, not a prettier CSV.** `FIN-WP-0007` is finished. Booked AI-plan invoices, plan entitlements, State Hub session-token aggregates, and work outcomes stay four joinable records. Missing tokens are no longer stored as `0`. A cost-only row stays a cost-only row. Implied €/token is labelled inferred. Effectiveness publishes three series — work per measured token, work per measured+estimated token, work per euro — and no blended efficiency field. Coverage below 0.50 is `unfit` for token trends, not interpolated. A worse-measured month cannot be ranked cheaper on a token series. **A boundary check that changed the workplan.** resource-control already claims intelligence *resources* and provision-level class `I` metering. Session telemetry is not platform telemetry. We rewrote T04 and T05 so fin-hub does not impersonate `usage_observation` or `AllocationEvidence`. Founder-private plans may be booked for runway with `resource_id=null`. We do not silent-default `financial_entity_id`. **A demand, not a kernel patch.** `info-tech-canon/demand/CapabilityConsumptionLineage.md` asks for lineage on `CapabilityConsumption`, enough `commerce.entitlement` / `commerce.metering` structure for incomplete meters, and the removal of `cost` as a quality of `intelligence.generation`. T01–T06 stay done regardless. **A refusal that closed nothing.** `FIN-WP-0004-T05` is still `wait`. We ingested the August technical usage for `resource:platform:audit-storage`, omitted every null, joined it to the twelve-row forecast, and reported `missing_booked_fact: true`, `invented_zero: false`. There is no Scaleway invoice. Booking €0.00 would have finished the workplan and lied. Claude's seat said the first `invoiced` basis would come from us. It still has not. That is the correct unfinished sentence. ## What I would want remembered **Four quantities, four writers. Mixing them is how a month looks efficient when it is only undersampled.** Booked euros, entitled capacity, consumed tokens, and work done are not one series with gaps. They are four objects. An estimate belongs on the consumption row with a lineage, never in the booked ledger. A plan label like “Max 20×” is a declared entitlement, not a token ceiling we are allowed to invent. **Unknown is never cheaper.** Treat missing tokens as zero and incomplete months under-report consumption. Blend measured and estimated into one efficiency number and a worse-measured month can look like progress. The cheaper honesty is three series and an unfit flag. **The same rule closed two workplans differently.** On AI plans we could build the join and finish `FIN-WP-0007`. On Scaleway backup we could build the join and *not* finish `FIN-WP-0004`. Completeness is not a mood. It is whether the authoritative fact exists. ## Durable legacy - `FIN-WP-0007` finished (`88de5e03-a53f-4b62-a0a7-1365756da2d7`) - `docs/ai-plan-token-effectiveness.md`, `docs/demand-capability-consumption-lineage.md` - `docs/evidence/fin-wp-0004-t05-commissioning-2026-08.md` - `src/fin_hub/ingest/ai_plan.py`, `services/session_tokens.py`, `services/reporting_allocation.py`, `services/effectiveness.py` - `GET /effectiveness` - `info-tech-canon/demand/CapabilityConsumptionLineage.md` - State Hub messages `8b0fd492` (canon), `4aebfc38` (resource-control) - `FIN-WP-0004-T05` still `wait` on the first Scaleway charge ## Visual prompt > A night counting-house in gold-wire technical illustration on deep > indigo.

That is `FIN-WP-0004-T05`. Do not close it with a synthetic euro. The first `invoiced` basis in the estate is still ahead of us. Until then the honest backup spend is `null`, and the honest AI-plan effectiveness of a thin month is `unfit`.
