Implements the CLAUDE.md cross-cutting invariant "brief framing must match
operator intent" as a controlled brief_version 2.1->2.2 bump (operator option A1).
Three defense layers, version-gated at >=2.2 so existing 2.0/2.1 briefs stay
valid (forward + backward compatible), mirroring the phase_signals >=2.1 gate:
- L1 framing: enum field (preserve|refine|replace|new-direction). Enum-checked
on any version when present (BRIEF_INVALID_FRAMING); missing at >=2.2 ->
BRIEF_MISSING_FRAMING. /trekbrief Phase 2.5 collects it BEFORE any brief prose
(non-skippable, even in --quick).
- L2 memory alignment: new brief-reviewer dimension 6 comparing brief Intent/Goal
+ framing against operator memory for explicit contradictions; degrades to
score 5 (N/A) when no memory context is supplied. Wired into Phase 4e gate
(memory_alignment.score >= 4).
- L3 obligatory ## TL;DR (<=5 content lines) at >=2.2; soft cap ->
BRIEF_TLDR_TOO_LONG warning.
trekreview briefs are exempt from the framing/TL;DR gate. Handover 1 PUBLIC
CONTRACT doc, README "What's new", and the CLAUDE.md invariant + agents table
(brief-reviewer 5->6 dimensions) updated to 2.2 (schema axis only; plugin
version badge + CHANGELOG remain S10).
Iron Law followed: validator tests red->green first. Tests 586 -> 606
(+20, 604 pass / 2 skip). claude plugin validate passes (pre-existing
CLAUDE.md root-context warning unchanged).
