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.

Step 19 of v4.1 — extend-in-place per brief Preferences. Three new test
blocks asserting forward-compat:
1. Legacy fixtures (plan-run-A.md, plan-run-B.md) — without profile_used
in frontmatter — still parse cleanly after manifest-yaml.mjs added
OPTIONAL_STRING_KEYS.
2. New fixtures (profile-plan-run-{economy,premium}-*.md) — with
profile_used in frontmatter — parse cleanly with correct profile
value extracted.
3. Real v4.1 plan (.claude/projects/2026-05-08-voyage-v4.1-modellprofiler/plan.md)
validates strict, emits no PLAN_VERSION_MISMATCH warning.
Tests: 475 pass + 2 skipped (Docker not installed).
Step 17 of v4.1 — escalate-handler invoked. Live LLM-budget ($60-120 for
4 plan-runs á /trekplan --profile {economy,premium} on
examples/01-add-verbose-flag/brief.md) was not authorized for the
v4.1-execute-4b session.
Per Step 17 escalate-fallback (and NEXT-SESSION-PROMPT.local.md
fallback-strategy): document economy-Plan as parked, use balanced as
low-threshold profile, defer empirical calibration to v4.2.

Replacement procedure documented in calibration.md "How to replace"
section. Trigger conditions for empirical re-run:
1. Cross-tier smoke-test (Step 18) flips red on a real run
2. v4.2 LLM-budget approval
3. New profile tier added
Adds 6 files in tests/synthetic/ exercising the determinism pipeline at the
SC7 brief floor (Jaccard >= 0.833). Plan fixture pair: 40 step titles each
with 38 shared (Jaccard 0.905). Review fixture pair: 30 finding-IDs each
with 28 shared (Jaccard 0.875). Reuses lib/parsers/jaccard.mjs +
lib/parsers/finding-id.mjs.
The new pair coexists with tests/lib/review-determinism.test.mjs which
holds the older SC4 (0.70) floor against tests/fixtures/ultrareview/.
The lower floor protects pipeline regressions; the higher floor anchors
the speedup brief's determinism aspiration.
