Drew T ce88baf365 feat(phase-27 T9): calibration — the templatability swing measured (structural families are NOT cheap)
docs/calibration.md — the byte-gate-grounded rates that size P28/P29 (roadmap §6 held yield
projections until this).

- VELOCITY: instr 68.9->67.0% (a T7 denominator re-baselining DOWN, not a regression) + ~0 matches
  banked (an infrastructure/findings phase). The honest flip-checkpoint read: denominator correction
  + unblocking findings, NOT 0 progress/session — velocity resumes at P29, re-measure there.
- THE TEMPLATABILITY SWING (decisive for P28/P29): h_exact reach-N cores propagate ~xN near-100%
  (§52: 5 cores -> 670 instances) vs h_seq/h_norm structural families ~0% (0x8017BEBC: 106/112 stage
  but 0/8 bank, all genuine DIFF). So remaining yield = per-member cracking + mechanical xN for the
  h_exact cores, NOT "template x120 the 986 families" — B1/B2's cheap-harvest hope is byte-refuted.
  The 223-stub frontier: 101 reach-134 (xN-able if cracked) + 119 reach-1.
- COST/TIER: Fable5 ~230k tok/fn, 0 banks / 5 — ROI is idioms + the pin-crash wall dissolved, not
  banks (the doctrine held). cheap-Opus is the banking tier; permuter tail exhausted; local-v3 $0/<=15.
- HONEST GAP: the headline member-adapt close-rate on register-drift members needs P28's member_adapt
  tool (chicken-and-egg) -> P28 opens by measuring it on a byte-gated sample, per the risk register.
- NEW un-projected fuel: ~20 PINS-class stubs now harvestable (pin-crash dissolved, T5).
