lab/app.py (users, tenants, auth, resources, sharing, read/write, revoke,
audit), lab/http_api.py (JSON API + browser UI, stdlib only), 20 labelled
composable version-stamped mutations, ground-truth matrix. 48 tests pass.
Detection against the reference scenario: MECHANICAL 0/10 flagged (correct),
DEFECT 6/6, SEMANTIC 2/4 with both inert cases declared.
- F-0002: M16 and M18 initially escaped detection entirely. A use case
protects exactly what it asserts. Resolved by adding two claims already
stated as intent in INTENT.md; the six-mutation catalogue would never have
surfaced this.
- test-id axis added: stable selectors survive most UI mutations, which would
make H-001 trivially false. Mutations now vary on preserves_test_ids so the
hypothesis is analysed split by that axis rather than rigged.
- M12 (semantic deferred revoke) and M19 (defect race) are behaviourally
identical and asserted as such - the discrimination problem as a test.
lab/minimal.py removed; superseded by lab/app.py.

Alice/Bob/Carol runs end to end, deterministically, replayable from seed.
16 tests pass, no third-party dependencies.
- src/testdriver: intent, provenance, world, actions, drivers, observers,
oracles, evidence, energy, scenario, runner
- lab/minimal.py: the SUT, exposing the independent observation channel
required by D-07
- evidence is stratified S1/S2/S3; Runner refuses to attribute S2/S3 to an
actor; claims are frozen and provenance-checked at construction
- missing evidence yields INCONCLUSIVE, which outranks PASS in the run verdict
- EnergyEvents captured, no scoring (H-005 dormant)
The observation channel records both stored state and an out-of-band
enforcement probe; their disagreement is an invariant and is what detects an
authorization defect that leaves the audit trail intact. A seeded
RevokeIsCosmetic lab fails the run via both the claim and that invariant.
Also closes TD-WP-0001-T02 (stack and commands now exist).

H-001..H-005 with explicit falsification conditions, E-001..E-003, the
Concept-Implementation Fitness Map, findings log and ID convention. Plain
files, no tooling.
- fitness map corrects Improvement Loop section 13 levels downward: nothing
exceeds C1 without implementation
- H-005 (Energy) dormant by decision - events captured, no scoring written
- H-001 gets a genuine control arm so the semantic-action thesis is not
trivially true
- E-003 added: deliberately attacks the safety boundary rather than only
sampling benign cases

Answers the two questions gating the rest of TD-WP-0002.
Classifier: stratify evidence into S1 surface / S2 realization / S3 judgment.
Adaptation writes only to S1; claims and invariants are run inputs with no
adaptation write path, so False Adaptation Rate = 0 is architectural rather
than a tuning target. Classification is a total function over three signals,
defaulting to AMBIGUOUS on missing evidence; a surface change concurrent with
a verdict change is PRODUCT_DEFECT. Semantic actions declare permitted
surfaces so surface-substitution cannot pass as recovery.
Provenance: claims require a source causally independent of the
implementation. agent-from-implementation output is an exploratory hypothesis
until a human promotes it.
New adoption precondition D-07: test-driver requires an independent
observation channel into the system under test.

Three documents defined conflicting milestone sequences; an unqualified
reference to e.g. 'M2' was ambiguous across the corpus.
- docs/TestDriverInitialMilestones.md (M0-M10) is now canonical
- INTENT.md and ConceptModel section 15 carry superseded banners plus a
mapping table rather than being deleted
- canonical order is explicitly distinguished from execution order
- research/findings/ established; F-0001 filed as CONCEPT_DRIFT, resolved
via path 2 (concept deliberately revised), with one residual for T10
