docs(voyage): plan W1 narrow-wins implementation (NW1/NW2/NW3, S9->)
Operator decision (2026-06-18): implement ALL narrow wins from the S7 (CC-26)
and S8 (CC-27) gates, starting next session.
NW1 (S8 tier 1, ungated): reviewer-output schema contract — retires the
JSON-parse fragility at trekreview.md:202-204; no Workflow dependency.
NW2 (S8 tier 2): trekreview Phase 5-6 Workflow port as opt-in --workflow path,
gated on a fidelity bake-off.
NW3 (S7 PoC): trekplan Phase 7 synthesis-agent, gated on measured delta
main-context >= 30%.
Sequence S9 NW1 -> S10 NW2 bake-off -> S11 NW2 integrate/decline -> S12 NW3
measure/adopt -> S13 RELEASE. Each implementing session is TDD (Iron Law);
numeric guards act as regression guards (surface to operator), not silent veto.
Open decision: NW2 integration posture (opt-in flag [recommended] vs default).
Wholesale substrate swap / wholesale delegation remain DECLINED (out of scope).
New: docs/W1-narrow-wins-plan.md. Docs-only; no code/schema change.
