tegwick bec7fdc465 T03: research control plane
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

Concept ↔ Implementation Fitness Map

Updated: 2026-08-22 (TD-WP-0002-T03)

Traces each important concept to the implementation, experiment and evidence that support it. Unsupported entries are the point of this map — a concept with no implementation and no evidence is not a gap to be embarrassed about, it is the current honest state, and hiding it defeats the map's purpose.

Support levels follow TestDriverImprovementLoop.md §13: C0 Idea · C1 Hypothesis · C2 Experimentally Supported · C3 Practically Validated · C4 Architectural Invariant

Current state

At the time of writing there is no implementation, so no concept can honestly exceed C1. The initial classifications in §13 of the Improvement Loop (Actor Isolation C2, Independent Oracles C2) are corrected downward here: they were aspirational, not evidenced.

Concept Level Implementation Experiment Evidence Open question
C-use-case C1 — (T04) Is a use case expressible without leaking mechanics?
C-actor-isolation C1 — (T04) E-001 Isolation is asserted by construction; unverified.
C-semantic-action C1 — (T04) E-001 Does identity survive restructuring better than a recorded sequence? (H-001)
C-oracle-independence C1 — (T04) E-001, E-003 Independence of components ≠ independence of belief. (H-004)
C-evidence-pack C1 — (T04) What is the minimum sufficient for replay?
C-observation-channel C1 — (T05) D-07 — required of every system under test. Adoption cost unknown.
C-adaptation C1 — (T08) E-001 (H-002)
C-classification C1 — (T08) E-001, E-003 Decision table is total on paper; unexercised.
C-crystallization C1 — (T09) E-002 (H-003)
C-intent-provenance C1 — (T04) E-003 Constrains provenance, not quality. Accepted residual.
C-lineage C0 Parent pointer only in the spike.
C-energy C0 events only (T04) Dormant by decision. (H-005)
C-temperature C0 Deferred. No implementation planned in TD-WP-0002.
C-confidence C0 Deferred.
C-campaign C0 Deferred.
C-metabolism C0 Deferred. Depends on C-energy.
C-retirement C0 Deferred. Depends on C-energy.
C-security-mutation C1 E-003 Catalogue exists; no derivation mechanism.

Orphan check

Conceptual orphans — concepts with no planned implementation in TD-WP-0002: C-temperature, C-confidence, C-campaign, C-metabolism, C-retirement.

All five are deferred by explicit decision, not oversight. They are the group most at risk of being built because they are easy and satisfying, and never validated. They are revisited at T10, where the question is not "when do we build these" but "does the evidence justify keeping them in the model at all".

Implementation orphans — none yet; there is no implementation.
