event-emit returned {written:false, reason:'CLAUDE_PLUGIN_DATA unset'} whenever the harness did not export the variable - the normal case for the Bash tool - so /trekexecute's Phase 8 events never landed. It now resolves the directory through stats-append's resolveStatsDir (one resolver; opts.path still wins, so intent-approval is unchanged). The CLI uses the realpath isMain() guard (the file:// guard was a silent no-op under a symlink or a path with a space) and exits 1 on every written:false - usage error, payload-not-json, failed write - instead of always 0. KNOWN_EVENTS gains main-merge-approved, main-merge-declined and gates_mode_flag_override, which /trekexecute emits by design. Header, intent-approval docstring (comment only), docs/operations.md and the README autonomy sentence (wrong state names, 'records each transition') updated.
Red: 10 of 20 tests fail on the pre-fix code - 7 new (CLI lands with CLAUDE_PLUGIN_DATA empty / absent, unwritable target exit 1, usage error exit 1, symlink, space path, known events) and 3 inverted contracts. Regression guards (green on arrival): never throws when unwritable; no second copy of the fallback directory name.
Inverted (the contract this changes, not deleted): emit with no CLAUDE_PLUGIN_DATA (silent skip) -> lands under a pinned HOME; never throws when unwritable -> a genuinely unwritable target (env {} now resolves to the real home); resolveStatsPath({}) === null -> the fallback path; malformed --payload exit 0 -> exit 1.
Readers checked: otel-export keys on 'event', yardstick counts only user_input, cache-analyzer and research-loop-cap name event-emit only in comments. Verify 268/268 (stats-event-emit, intent-approval, doc-consistency, otel-export-validators, yardstick). Suite 1376 (1374/0/2); non-hook lines in the real trekexecute-stats.jsonl 60 before and after.

appendStatsRecord(kind, record, env, { cwd }): for kind trekbrief it drops
every order_* key the record came with and adds attributeOrder()'s three
keys (lib/stats/claimed-order.mjs), resolving the mailbox from the record's
project_dir when that lies inside cwd. Other kinds are written untouched.
The CLI guard compares real paths (realpathSync on argv[1] and on
import.meta.url). The old `import.meta.url === file://${argv[1]}` was a
silent no-op - exit 0, nothing written - under a symlink and under a path
with a space (measured 04.10). Valgt realpath fordi `resolve()` alone fixes
only the space.
stats-landing 15/15; intent-approval, claimed-order, proevesett green.

lib/stats/claimed-order.mjs reads <coord>/<mailbox>/orders/claimed/ the way
repo-mailbox's claim verb writes it (read, never called): the stem is the id,
the .claim sidecar gives claimed-at, every .md counts toward "several".
Mailboxes come from two independent git calls (toplevel basename, the claim
script's rule; and the main repo behind a linked worktree), with GIT_DIR /
GIT_WORK_TREE dropped and a 5 s timeout. A project_dir outside cwd cannot
steer the lookup. Never throws, never guesses, starts nothing.
Valgt: identity = file stem, not frontmatter, fordi the claim script moves
<id>.md and never reads the frontmatter; a quoted order-id would otherwise
never join.

New lib/stats/stats-append.mjs: one record on stdin, appended to
<data dir>/<kind>-stats.jsonl. The data dir is CLAUDE_PLUGIN_DATA, else
~/.claude/plugins/data/voyage-ktg-plugin-marketplace (the yardstick's
default). A failed write exits 1 with a reason: reported, never silent.
/trekbrief Phase 7 and /trekplan Phase 12 now run it instead of
"append to ${CLAUDE_PLUGIN_DATA}/…; skip silently". intent-approval's
resolveApprovalDataDir delegates to the same resolver.
Chose a stdin heredoc over a --json argument because a JSON record in a
shell argument breaks on quotes in task text. Only trekbrief and trekplan
are rewired (økt 2's countable form needs exactly those two); the other
commands' stats prose is unchanged and docs/architecture.md says so.
Red a358059 7/7 → green 7/7. Suite 1208: 1206 pass / 0 fail / 2 skip.

Implements Spor C of post-v3.4.0 roadmap. Zero-dep harness measures
CLAUDE_CODE_FORK_SUBAGENT cache-prefix preservation across 3 fork-children
with identical --allowedTools at 150-250K parent context.
Harness uses --append-system-prompt-file (avoids stdin buffer cap at
>200K bytes) + --exclude-dynamic-system-prompt-sections (prevents
per-child cache-prefix divergence from cwd/env/git-status).
Companion analyser summarizes accumulated ultraexecute-stats.jsonl:
percentile wall_time (p50/p90/max), total events, ISO time range.
Output: JSON via --json <path> CLI shim.
Result file is gitignored (*.local.md). Master-plan thresholds
(<= 1.5K positive / >= 3.5K negative) gate the v3.5.0 Path C decision.
