# End to end for fix round 4-5b, part 2 (plan
# .claude/projects/2026-10-27-fix-round-4-5b-part-2, End-to-end:, decision
# 88): the shipped products run the way a session runs them, in temp
# directories and temp git repos.
#   1. TOK: the arg parser (lib/parsers/arg-parser.mjs --command trekreview
#      --stdin) reads `--project "my dir"/x --since "HEAD~1"` from a quoted
#      heredoc, and its JSON keeps `--since` = `HEAD~1`.
#   2. HDG: the Bash hook (hooks/scripts/pre-bash-executor.mjs) with a Bash
#      tool input on stdin:
#      a. a one-line `grep` that mentions the parser's heredoc opener exits 0;
#      b. a parser heredoc that closes early exits 2 (args-heredoc-closed-early);
#      c. a quoted first mention hiding an unquoted parser heredoc exits 2
#         (args-heredoc-closed-early).
#   3. CKI: `recurrence.mjs apply` in a repo whose `.claude` is a symlink to an
#      in-repo directory: the lesson is written, `pointer` is `check-failed`,
#      and CLAUDE.md is unchanged.
# DLC is prose (commands/trekexecute.md Sub-step G); it is checked by
# tests/lib/fix-round-4-5b-part-2-prose.test.mjs, not by this run.
# Prints one "ok - <case>" or "FAIL - <case>: <why>" line per case and exits 1
# when any case failed, else 0. Starts nothing but node and git (and the
# usual file tools). bash 3.2 compatible, ASCII only, no arrays.
