Shay 394029008e feat(adr-0024): Phase 1 addendum — retire v1/dev fixture rot
Rewrite v1+dev FSC cases with pack-grounded tokens drawn from
en_core_cognition_v1. Closes the 9/9 region-construction failure
recorded in Phase 4 (chain_tokens alpha/beta/gamma/delta/etc. were
ungrounded in the active pack).

Token mappings preserve each case's test pattern:
* alpha→beta→gamma→delta  →  tone→evidence→memory→wisdom (causes)
* mu→nu→omicron           →  voice→memory→wisdom (means)
* pi→rho→sigma→tau        →  question→answer→understanding→wisdom (precedes)
* upsilon→phi→chi         →  word→discourse→narrative (part_of)
* eta/theta/zeta + means-distractors → symbol/word/meaning + image/light

Result post-rewrite:
* skipped_count: 9/9 → 0/9 (region constructible)
* causal_attribution_valid: True (preserved)
* code_path_residual: 0.0 (preserved)
* inner_loop_t0 hash stability: 1.0 (preserved)
* best_separation_quality: 0.0 → 0.056 (still below 0.8 gate)

The rewrite exposes a deeper architectural finding documented in the
ADR addendum: v1/dev case schema (prime + chain_tokens) probes
teaching-driven walk (ADR-0022/0023), not the inner-loop's
blade-admissibility mechanism (ADR-0024). The Phase 2 corpus-
observation runner's reuse of v1/dev was a categorical error.
v1/dev belong to the boundary-walk lane (runner.py); v2 belongs to
the inner-loop lane (v2_runner.py). Phase 5 will author the benign
inner-loop corpus the EXHAUSTION_CEILING gate was designed against.

Tests pinning new state:
* TestV1ChainBladeUngrounded → TestV1ChainBladePostGrounding
  (assertions inverted: skipped_count == 0; separation_quality < 0.5)
* TestPhase2 (unchanged) continues to assert causal_attribution_valid
  and hash stability; exhaustion remains a finding, not an invariant.
