tegwick 04e9573b5a T04: deterministic semantic kernel
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).

"""Energy events — capture only.
H-005 is dormant by decision: verification energy is not testable at the current
scale, and a scoring function producing a number nobody can check is worse than
no number. Events are recorded from the first run because history cannot be
reconstructed later; scores always can.
There is deliberately no score() function in this module.
