Elevate Handover 1 (brief.md → research) from an internal pipeline handover
to an explicit PUBLIC CONTRACT — the only public producer↔Voyage integration
boundary (Trinity asymmetry invariant: Voyage stays unaware of upstream tiers;
any compatible producer may feed it; no producer privileged).
Scope = freeze + document (operator-gated, option A). No schema change, no
plugin version bump (that is S10 RELEASE). Per S3, phase_signals stays optional
and brief_version 2.1 is the frozen public-contract baseline.
- docs/HANDOVER-CONTRACTS.md: PUBLIC CONTRACT label + callout on Handover 1
(asymmetry, breaking-for-downstream, additive-vs-breaking, frozen 2.1 baseline);
resolve the speculative "v5.4 may promote phase_signals to required → 3.0" line
to the S3 freeze decision; fix stale schema-table baseline 2.0 → 2.1; annotate
the Stability summary row (symmetric with Handover 3's "external" flag).
- CLAUDE.md: Trinity note now points at docs/HANDOVER-CONTRACTS.md §Handover 1.
- tests/lib/doc-consistency.test.mjs: +4 failing-first doc-truth pins (Iron Law)
— PUBLIC CONTRACT label, callout + breaking-for-downstream guarantee, frozen
2.1 baseline (no stale 2.0), freeze-not-promote. 586/584 pass/0 fail/2 skip.
