Follow-up to 63e78c5. Adversarial review found that the fix had reintroduced,
in a smaller form, the exact defect the order was filed about.
1. The rewritten Check 2 block opened with
`git ls-files --error-unmatch "$PLAN_PATH"` while the assignment lived in
the prose above it ("Set PLAN_PATH to the plan path, then run:"). Nothing
upstream sets it — Check 2 is Phase 2.55, and REPO_ROOT/WORKTREE_DIR are
only created in Phase 2.6 Step 1, which runs after. An agent copying the
block verbatim would have run it with PLAN_PATH empty. The note was prose,
the code was what ran. The block now carries
`PLAN_PATH="{plan-path}"` as its first line, the same placeholder idiom
the rest of the file uses (`BRANCH_NAME="trek/{slug}/session-{N}"`).
The three Check 2 tests could not have caught this: they injected
PLAN_PATH through the environment, supplying what the doc has to supply
itself. They now substitute `{plan-path}` the way an agent does, assert
the placeholder is present, and pass PLAN_PATH="" in the environment so a
block that fails to assign it goes red. Control run with the assignment
line stripped: `fatal: empty string is not a valid pathspec` -> exit 1.
2. Both copied blocks contained an em-dash (one in an `echo` string, one in a
comment). Shell that bash 3.2 executes stays ASCII — a multibyte char
under `set -u` has crashed it before. Replaced with plain `-`; the prose
outside the fences keeps its em-dashes. New test asserts both blocks are
ASCII-clean, with a known-positive proving the detector fires on an
em-dash.
Suite 1022 (1020/0/2) -> 1023 (1021/0/2). No version bump, no release.
63e78c5 stays valid in history: the order archive and two coord messages
point at it.

Two independent defects took down a real voyage on macOS today
(llm-ingestion-okf, wave 1, zero steps executed). Both paths led to the same
end state: the worktree had no plan.
1. Phase 2.6 Step 2a' derived the project relpath with
`realpath --relative-to`, which is GNU coreutils only. On BSD realpath
(macOS default) the substitution fails silently: PROJECT_REL ends up
empty, `mkdir -p "$wt/"` and `cp ... "$wt//"` both succeed, and
brief.md/plan.md land at the worktree root where no child session looks.
The portable form existed only as a prose note saying an operator "may
substitute" it — the note was prose, the code was what ran. The block now
uses `python3 -c os.path.relpath` (stdlib), resolves both operands with
bare realpath (identical on BSD and GNU, and correct across the macOS
/var -> /private/var symlink), and aborts loudly when the relpath is
empty or escapes the repo instead of dropping files at the root. The
coreutils note is deleted rather than extended: two forms means the next
reader picks, and that pick is what failed.
Measured on this machine 2026-08-31 (Intel Mac, no coreutils):
`realpath --relative-to=...` -> `realpath: illegal option -- -`;
bare `realpath /Users/ktg/.claude` -> correct path, exit 0.
2. Phase 2.55 Check 2 ran `git add {plan-path}` unconditionally. When the
project directory is gitignored (`.claude/projects/` is tool-managed and
local-only — normal, not exotic) the add refuses and the plan never
reaches HEAD. Check 2 now probes with `git check-ignore` and branches:
tracked -> nothing; untracked -> add + commit as before; ignored -> step
aside and let Step 2a' be the delivery path. `git add -f` was rejected as
the fix: forcing operator-local artifacts into history publishes them to
whatever remote the repo pushes to. A `check-ignore` exit code other than
0 or 1 is fatal and stops execution — a probe that failed is not a probe
that answered "not ignored".
Also fixed in the same block: `[ -d research ] && cp -r ...` as the last
statement of the loop body made a project without research/ exit the wave
non-zero.
TDD, Iron Law: tests/commands/trekexecute-parallel-portability.test.mjs
extracts both shell blocks from commands/trekexecute.md by grep-able anchor
and executes them, so the tests bind to what an agent actually copies. The
assertions check FILE PLACEMENT, not exit status — the whole defect is that
the broken form exits 0. Controls, all present before the fix: a
known-positive BSD-realpath stub (bare path resolves, GNU flag rejected with
`illegal option`), a negative control running the old GNU form under that
stub and asserting plan.md lands at the worktree root, a known-positive
Check 2 arm where a non-ignored plan is still added and committed, and a
stubbed fatal `git check-ignore` (128). Red first: 7 failed, 2 passed (the
two controls). Green after: 9/9.
Suite 1013 (1011/0/2) -> 1022 (1020/0/2). No version bump, no release.
Order: 20260831T214411Z-941965142-from-.claude (from .claude).
