Closes devils-advocate audit #4–#6 (MAJOR×MED). Four additive, non-breaking
changes to the v5.5 framing-alignment machinery:
1. --min-brief-version <ver> gate (audit #4). Opt-in version floor on
/trekplan + /trekresearch, forwarded to brief-validator as --min-version.
New opts.minBriefVersion warns BRIEF_VERSION_BELOW_MINIMUM (never blocks)
when a brief declares a version below the floor; trekreview exempt; absent
opt = no check. CLI shim parses --min-version and skips its value token in
filePath detection.
2. memory_alignment.status field (audit #5). brief-reviewer now emits
status: verified | n_a | contradictions so a score-5 N/A (no memory) is
distinguishable from a score-5 verified-aligned brief — the score≥4 gate
passes in both, status reveals whether the wrong-premise defense ran.
3. Document pre-2.2 = zero framing enforcement (audit #4). HANDOVER-CONTRACTS
§Handover 1 now states the producer-elective hole + two remedies. Also
fixes a stale "current is 2.1" line (current is 2.2).
4. Soften flagship overselling (audit #6). CLAUDE.md Context-Engineering
principle now hedges that main-context relief is asserted-by-design, not
measured (T1 PoC found Δ≈0); README carried no false claim to fix.
TDD: 8 new tests written failing-first (5 validator, 1 trekbrief status pin,
2 doc-consistency cross-file pins). Suite 691→699 (697 pass / 2 skip / 0 fail).
No flagship prose-pin added (deliberate, per S19 anti-bloat).

8 sites across 3 orchestrator agents + trekbrief/trekplan/trekresearch asserted 'the harness does not expose the Agent tool to sub-agents' as present fact -- the rationale for the v2.4.0 inline migration. CC 2.1.172 (verified) lets sub-agents spawn sub-agents up to 5 levels deep, so the claim is false. Replaced each with verified history (pre-2.1.172) + current fact + forward pointer to the decision matrix (W1/CC-26). Decision-neutral: states fact without pre-empting the orchestration redesign. CHANGELOG history left untouched. Tests 578/0/2; claude plugin validate passes.

Flip model: sonnet → model: opus across 20 agent files, 4 prose references
in commands (trekplan, trekresearch), trekendsession command frontmatter,
and CLAUDE.md tables. Aligns CLAUDE.md premium-profile row to actual
premium.yaml content (all-opus, which has been the case since v4.1.0 but
the doc was drift). Companion to VOYAGE_PROFILE=premium env-var (set in
~/.zshenv same day) — env-var governs orchestrator phase model; this
commit governs sub-agent models which are frontmatter-pinned and not
reachable by the profile resolver.
npm test: 516 pass, 0 fail, 2 skipped (unchanged from baseline).
Operator rationale: complete Opus coverage across all Voyage activity,
including the 20 sub-agents that the profile system does not control
(architecture-mapper, task-finder, plan-critic, scope-guardian,
brief-reviewer, code-correctness-reviewer, brief-conformance-reviewer,
review-coordinator, session-decomposer, plus the 6 researcher agents,
plus the 5 codebase-analysis agents).
Cost implication: sub-agent runs ~5x more expensive vs sonnet. Accepted.
