Closes the scope gap census 01 declared for itself: the seven instruments it named as uncensused. Pre-registered before any source or config was read, with predictions and a discrimination condition. Census 01 asked whether an instrument had a real negative instance — a question about CAPABILITY. Census 02 asks whether it has ever engaged in real life. Those come apart exactly at the drift-checker's shape, and 2026-08-04 found the gap six times (retrieval_count = 0 across 19,915 nodes for four months; two replay modules that have never processed an event). VERDICT: every instrument a human runs by hand has a rich firing record; every instrument that runs by itself has none — and the two guarding the engine's output have no consumer at all. The record divides by whether a human is in the invocation path, not by age, quality, or importance. verify-before-compose fired exactly twice (2026-07-17, 2026-07-18), evidence surviving only in harness transcripts; and it CANNOT fire on 31 of 59 guarded files, including the live constitution, because it folds the existing file's contents into its search for the attestation. audit_cruft, verify_conversion and apply_char_glyphs are exemplary. resolve_archived_source is healthy at 349/349 and has zero log entries. studium verify-quote and fidelity_equivalence@2 have no production call site at all. Prediction 5 inverted for the second census running, for a new reason. Census 01: decay, not construction, is the failure mode. Census 02: the recording is attached to the human, so an instrument's record vanishes the moment it is automated — which is when it starts running often enough to matter. Two of my own candidate findings died to their controls and are recorded as such: probing the resolver with engine source_ids against the chamber's canonical_slug key space (one sentence from "the resolver is inert"), and reading character_as_image at the wrong YAML nesting (nearly "zero glyph maps declared"; there are two sources and a 63-item census). Filed together: PENDING-95 [HARDENING] the hook cannot fire on the constitution · PENDING-96 [HARDENING] "SILENCE — ✓ warranted" certifies the index and claims the answer · PENDING-97 [PROPOSAL] FTS AND-s bare tokens with no semantic layer, recall dies as questions lengthen · PENDING-98 [HARDENING] firing history exists only where a human invokes.

Census 02 — Has each instrument ever produced a positive result?
Pre-registered: 2026-08-04, before reading any of the seven instruments' source or config. Origin: the literal question left by the 2026-08-04 wrap, closing the scope gap census 01 declared for itself.
The question
Census 01 asked: does each instrument have a real negative instance to test against, and is its absence recorded? That is a question about the instrument's capability.
2026-08-04 found something one level more basic, six times over: an instrument can pass every check ever run against it while never having fired at all. retrieval_count = 0 across 19,915 nodes for four months. coherence_evaluated = 0 of 813,178 chains. ANALYZE never run in four months. Three of five governance-drift-check.py families inert. Two L1 replay modules that have never processed a single event — pinning the resume floor at zero and making every restart a full rebuild.
So, of each instrument: has it ever produced a positive result — ever actually fired, matched, blocked, or caught something in real use — and does a record exist that could tell us either way?
An instrument can be DEMONSTRATED at build time (census 01's gold standard) and inert ever since. That is not a hypothetical; it is precisely the drift-checker's shape.
Unit of census
The seven instruments census 01 explicitly declared out of scope, censused entire:
verify-before-compose(the PreToolUse hook)audit_cruftverify_conversionresolve_archived_sourceapply_char_glyphs- studium-engine
verify-quoteV1 fidelity_equivalence@2
The test applied to each
Two independent axes, recorded separately. Conflating them is the error this census exists to avoid — "it works" and "we can tell that it works" are different claims.
- Axis A — engagement. Is the instrument currently reachable? Does its trigger condition still match the substrate as the substrate now stands? Answerable from source and config.
- Axis B — firing record. Does any durable record exist that would show a positive firing? Answerable by grep. A session transcript is not a durable record; a governance file, a log, a committed artefact is.
Four outcomes:
- FIRED-RECORDED — a durable record names a real occasion on which it fired.
- FIRED-UNRECORDED — it demonstrably can fire and prose or memory attests that it did, but no durable record exists.
- INERT — its trigger cannot currently match. It reports success by never engaging.
- UNDETERMINED — cannot be settled on either axis. Reported as unclassifiable, not dropped.
Predictions (recorded before the read)
verify-before-composeis currently LIVE and has fired at least once. ~0.75. Basis:MEMORY.mdcarries the standing preference "Don't fight the block" — which reads as a lesson earned by being blocked. That is prose attestation, not a record.- No durable firing record exists for
verify-before-compose. ~0.85. A PreToolUse hook blocks by exit code and stderr; the trace lands in a session transcript, which nothing reads. - At least one of the seven is INERT — its trigger has drifted from the substrate it watches. ~0.6. Basis: census 01's prediction-5 inversion (decay, not construction, is the failure mode) compounded by six instances found on 2026-08-04.
- The chamber-library tools (
audit_cruft,verify_conversion,apply_char_glyphs) are FIRED-RECORDED, via_curation/tool-evolution-log.md. Only ~0.5 — the log exists and the log records firings are different claims and I have checked neither. - Overall skew: FIRED-UNRECORDED dominant. The instruments work; the record of their working does not exist.
The census's own discrimination condition
A single instrument cannot discriminate anything. This census discriminates only if, across the seven, both a FIRED-RECORDED and an INERT (or FIRED-UNRECORDED) instance appear.
If all seven land in one bucket, the census has discriminated nothing and must be reported as such rather than as a result.
If the skew comes out opposite to prediction 5 — mostly FIRED-RECORDED — the first hypothesis to test is that I accepted a weak record as a firing record, not that our instruments are unusually well recorded.
Falsifier for the central claim
For any instrument reported as having fired: name the occasion and the artefact. If I cannot name them, the verdict is FIRED-UNRECORDED at best. "I remember it firing" is not a record — it is the thing this census is trying to tell apart from a record.
Stopping rule
Complete when all seven are classified on both axes. Unclassifiable members reported as unclassifiable.
Order of execution: verify-before-compose first — it is the only one of the seven that gates steward-facing writes, so silent inertness is worst there.
