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.

Operator resolved the 3 forks to the conservative option: D1 keep gemini-bridge
as an agent, D2 keep observability exporters + document the direct-export
rationale, D3 keep the 24-opus pin firm. Model + observability work collapses
from code-deletion to a documentation record; real code remains in V15 (export
trim) and V30 (economy calibration). Plan finalized to 4 sessions (S31-S34).

Operator mandated executing all §6 backlog items of voyage-vs-cc-balance-analysis.md.
This plans them across 6 sessions (S31-S36), one item/group per session, TDD-first,
direct surgical edits (not Voyage-pipeline dogfood).
Decision Register surfaces the 3 genuine forks the analysis deferred to the operator
(NOT presumed): D1 gemini-bridge keep-vs-remove, D2 observability keep+document vs
drop-to-collector, D3 the 24-opus pin keep-firm vs downgrade-mechanical-roles. Gated
sessions (S34/S35) wait on these; fork-free sessions (S31/S32/S33/S36) can run first.
Cross-cutting guards noted: doc-consistency + agent-frontmatter tests gate any
agent-count/model change. No Handover-1 change; no pin silently overridden.
