allowTurn() appends BEFORE the turn runs, so during granted turn N the
ledger holds N records. The hook denied at `used >= budget`, which blocked
every tool call of the FINAL granted turn: the primitive granted B turns
and the harness permitted B-1. Worse, an exhausted run therefore always
terminated through an exit-2 tool denial instead of the graceful "cap
exhausted" exit at commands/trekresearch.md - and the prose says in as
many words that exit 2 is not exit 1, so the model was pushed out through
the one exit it is told NOT to treat as a cap.
The review recommended denying at `used > budget`. Taken alone that fixes
the count and breaks the hook: once the O_EXCL claim (previous commit)
makes a breached ledger impossible, `granted > budget` can no longer fire,
and the case this hook exists for - the loop consults the gate, is denied,
and issues the tool call anyway - would be allowed. A deny branch that
cannot be reached is a dead security claim, which is the same thing S82
removed two of rather than leave standing.
So the denial itself became a record. allowTurn() appends a tombstone
{runId, exhausted: true} when it denies for budget, and the hook denies on
the tombstone. Both properties now hold at once:
granted == budget, no tombstone -> turn B is in flight -> ALLOW
tombstone present -> the gate already said no -> DENY
granted > budget -> breached, any cause -> DENY
A tombstone is not a turn: readLedger reports {granted, exhausted}
separately so it can never consume budget. allowTurn short-circuits on an
existing tombstone, so a hammered gate neither re-walks every slot nor
grows the ledger. The tombstone write is best effort on purpose - the
denial is already the correct answer, so a ledger that cannot take the
record must not turn a denial into a grant.
The parallel-boundary test now asserts GRANTED turns rather than raw
ledger lines, because the denied callers legitimately add tombstones.
Review finding 8eb53458ac3efec778094f9f03b09e1cc1077a09 (MINOR).
Operator decision: tombstone over the literal recommended_action.

CLAUDE_PLUGIN_DATA is empty in the Bash tool's process env, and the Phase 5
bash snippet is the cap's only caller. resolveLedgerPath() returned null there
and allowTurn() failed closed, so the budget gate denied turn 1 of every real
run: the loop this delivery exists to bound could never spend a turn, and the
pre-registered measurement could not be run at all.
resolveDataRoot() is now the single root for everything the loop writes --
CLAUDE_PLUGIN_DATA when the harness sets it, ~/.claude/voyage when it does
not. Three consumers resolve through it, which is the point: the cap ledger,
the PreToolUse hook's scope-marker lookup, and the command's bash snippets.
A writer and a reader that resolved the root separately are what made the
enforcement hook allow unconditionally in every real run while CLAUDE.md and
docs/architecture.md called it enforcing.
Same root cause, same commit:
- Marker write and remove now share ONE absolute-path guard and one root; the
write requires a non-empty CLAUDE_CODE_SESSION_ID before composing the path
(unset, the marker was named `.json`, which no lookup matches and no TTL
sweep cleans up).
- The per-turn gates resolve VOYAGE_ROOT with a plugin-cache fallback and
reserve exit 2 for "gate could not run". Interpolating an empty
${CLAUDE_PLUGIN_ROOT} ran `node /lib/...` -> exit 1, which the contract read
as "privacy gate says no" -- an unsatisfiable rewrite loop no query could
clear.
Two now-unreachable deny branches are removed rather than left as dead safety
claims (allowTurn's no_plugin_data_dir; the hook's uncountable-ledger deny).
The fail-closed stance stays where it is still real: a ledger that cannot be
WRITTEN denies the turn.
Verified end-to-end through the real bash snippets and the real hook with both
variables stripped and HOME sandboxed: marker written under the fallback root,
8 turns spent, 9th denied, hook exits 2, and exits 0 again after removal.
Note: the fallback exit-2 branch fires against the installed v5.9.1 cache,
which predates lib/util/research-loop-cap.mjs -- correct behaviour, and it
clears when the plugin is reinstalled.

CLAUDE.md claimed both STORM phases go inert when the flag is unset. Only
Phase 5 did: the flag check lives in research-loop-cap.mjs, and Phase 4.5
never invokes the cap — it was gated on effort: high alone. At high effort
with the flag unset, discovery still mined Phase-4 output and mutated the
dimension list, so `dimensions` diverged from `dimensions_baseline` and the
decline branch was unreachable for half the mechanism.
The code was the deviator, so the guard is fixed rather than the claim: the
Phase 4.5 skip-guard now names both conditions, with the reason inline.
Three surfaces scoped the flag to "the loop" and are corrected with it
(README, docs/command-modes, docs/architecture), plus the orchestrator phase
map. CLAUDE.md's claim is now true, but its stated MECHANISM was not — Phase
4.5's inertness comes from its own guard, not from the cap module — so that
sentence is corrected too.
New doc-consistency pin: the flag must be documented as gating both phases on
all four reference surfaces. Review finding 00a3af1a.

pre-agent-cap.mjs (S78) enforces the Phase 5 loop bound only while a scope
marker exists for the calling session. Nothing wrote that marker, so the hook
shipped correct but latent. Phase 5 now writes it at loop start and removes it
on all three exits.
- Write: ${CLAUDE_PLUGIN_DATA}/trekresearch-loop-scope/<session_id>.json with
{runId, startedAt}, keyed by CLAUDE_CODE_SESSION_ID. Verified 2026-08-12 that
this equals the session_id on the hook's PreToolUse payload.
- runId must be the same --run-id the ledger is counted under; a mismatched id
counts zero turns and enforces nothing.
- Fail-soft on write: the hook is defence in depth, research-loop-cap.mjs stays
the gate. Report and continue. The reverse (skipping the budget gate because
a marker exists) stays forbidden.
- Removal on every exit, load-bearing on the exhausted one: the hook keeps
denying WebSearch/WebFetch/Task while the marker is there, and Phase 6 spawns
agents. Crash is covered by the hook TTL, not by cleanup - stated as such
rather than claiming cleanup covers it.
- Marker written in Phase 5, not Phase 4.5: 4.5 mines already-retrieved Phase-4
results and spends no loop turns, so scoping there widens the window for
nothing. Pinned by a test.
Six pins in tests/lib/doc-consistency.test.mjs derive the directory name from
SCOPE_DIRNAME in the hook and the payload fields from marker.runId/startedAt,
so drift in either direction fails. hooks/scripts/pre-agent-cap.mjs untouched.
Verified end-to-end with the snippets as shipped: marker written -> hook allows
under budget, denies 8/8 at budget, allows again after removal; removal is
idempotent; unset CLAUDE_PLUGIN_DATA takes the fail-soft branch.
Suite 937 (935/0/2, baseline 931 + 6).

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.
