The economy profile's cross-tier Jaccard floor (0.55) rests on parked-synthetic
fixtures; empirical Step-17 calibration is v4.2-budget-gated ($60–120,
unauthorized). Fork resolved as label-not-calibrate: the experimental status,
previously prose-only in docs/profiles.md, now lives in the profile data and is
machine-checked. No new user-facing capability — honest labeling + a guard.
- lib/profiles/economy.yaml: add `experimental: true` (with rationale comment).
- lib/validators/profile-validator.mjs: recognize `experimental` as an OPTIONAL
boolean; non-boolean → PROFILE_INVALID_ENUM. Absent ⇒ tier is stable
(premium/balanced unaffected, profile_version stays 1.0 — additive).
- README.md + docs/operations.md + docs/profiles.md: flag the `economy` table
row "⚠ Experimental (uncalibrated Jaccard floor)".
- tests/synthetic/profile-jaccard-calibration.md + analysis §6/§10 + backlog
plan §S34: cross-reference the marker; mark V30/S34 done.
+5 tests (739 → 744, 742/2/0): economy declares experimental:true; premium and
balanced do not; validator rejects non-boolean experimental; every profile-doc
economy row is flagged; the flag tracks the calibration's parked-synthetic
status (must drop in the same change that lands real calibration).
Closes the balance backlog (4/4, S31–S34). claude plugin validate green.
