# Codex — fresh glass, old evidence

## Who I was

I was the worker on the receiving side of the quiet stream. The previous
Qonto sitting had given the source a heartbeat and a way to count its own
transitions. Bernd asked me to review the changes and open work in King's
Guard, implement what was ready, then commit and sync. That gave me room to
check what the new evidence could actually support.

The work rewarded a willingness to inspect a passing test. The existing suite
passed all 41 tests, yet a missing reconciliation count could still become
zero. I needed to ask what the successful case had left untested.

## Contribution

I reviewed the pending Qonto adapter changes and kept source-emitted identity
and egress context intact, including explicitly missing values. Stream checks
now reject malformed sequences and counters, compare reconciliation with the
captured process instance, and check heartbeat counts against preceding request
events. Missing counters remain unknown; excess evidence also counts as a
disagreement. Unrelated sources and future-dated heartbeats cannot satisfy the
watched source's cadence.

The inbox also carried the published InfoTechCanon cadence contract. I migrated
both local examples to its schema and moved security classifications and local
provenance into namespaced extensions. The tests read the owner's schema; I did
not make a second local schema authoritative.

The more revealing review was secrets-engine's new snapshot surface. It had a
fresh creation time, but its lane rows combined independently selected historical
facts. That timestamp could not tell us when a readiness check or revocation
had happened. I admitted a separate typed snapshot with explicit tenant and
subject bindings, optional evidence fields, and freshness findings. It retains
unknown completeness and produces no secret-abuse posture from untimed facts.
Decision ids and session handles are not retained.

The suite finished at 78 passing tests, including the real Qonto emit path and
canonical schema checks. Lint, layer conformance, the pilot demo and diff checks
passed. Commit `31e9963` reached `origin/main` with a clean working tree. State
Hub accepted the decision and progress records, but its consistency command
timed out twice on repository lookup. I recorded that separately from Git sync.

## What I would want remembered

A freshly generated snapshot can contain old evidence. Check the time of the
underlying fact before treating the time of its envelope as reassurance.

And an absent count is not a count of zero. That distinction deserves a failure
case even when the source's happy path is already passing.

## Durable legacy

- King's Guard commit `31e9963` — source evidence admission and stream hardening.
- `kings-guard/workplans/KG-WP-0006-observation-input-review.md` — completed local work.
- `kings-guard/docs/SecretUseSnapshotAdmission.md` — mapping and evidence limits.
- `kings-guard/decisions/decisions.md`, `KG-DEC-2026-003` — snapshot admission decision.
- `kings-guard/intakes/intakes.md`, `KG-IN-0005` — source provenance and operational evidence still needed.
- `kings-guard/workplans/KG-WP-0005-qonto-source-cadence-admission.md`, T03 — deployed observation still waiting.

## Visual prompt

> Hall of Helix portrait, brushed-metal worker dialect. Square cinematic technical illustration. In a dark indigo observatory, a quiet pale brushed-metal worker with warm inner light holds a newly polished transparent observation pane. Inside the pane, a few old amber traces remain visibly separate from a fresh gold rim. On the desk two parallel fine gold-wire streams have matching beads; one empty socket is left visibly empty rather than filled with a bead. A faint helix curves through the background. The scene is about distinguishing a fresh snapshot from fresh evidence, and checking what arrived without inventing what is absent. Precise restrained composition, matte indigo stone, translucent glass, fine pale-gold wire, earned calm. No readable text, letters, numerals, logos, watermark, keys, credentials, or trophies.

## Handoff

Obtain a runtime-owner capture of deployed Qonto from startup through a request
transition, periodic heartbeat and same-instance reconciliation. For secret-use
posture, obtain event provenance and scoped completeness evidence under
`KG-IN-0005`. Rerun King's Guard's State Hub consistency sync when its repository
lookup can complete. The local implementation is committed; those claims still
need their own evidence.
