// Prose pins for fix round 4-5b (plan
// .claude/projects/2026-10-25-fix-round-4-5b-findings): the fixes that are
// text a session or a helper reads. The tags in brackets are 4.5b ids from the
// round's brief (for example `[M4]`, `[M11]`); each tagged test fails on an
// assertion at be0b631, the round's start point. A sibling's test is tagged
// `[<parent id>] sibling:`.
//   M4   A git call the verdict gate cannot complete is reported as
//        `review-not-measured:`, never as a stale review: Handover 6 names the
//        prefix and lists review_version 1.1 as current, and /trekexecute's
//        main-merge gate maps it to "not measured" with the merge locked.
//   M11  Handover 6 states that only a full 40- or 64-hex reviewed commit is read.
//   E22e The park tool parks every file new in the attempt's diff, untracked or
//        staged but not in HEAD: its header and /trekexecute's resume paragraph
//        no longer say "still untracked".
//   M3   The "Back to planning" save line runs its git diff with --no-relative,
//        so a session in a subdirectory with diff.relative on saves every file.
//   M9   The review coordinator's Pass 2 text says what the lib does: a root
//        escape or a negative line refutes a finding; any other line number
//        alone never does, and a line past the end goes to `unverified`.
//   M2   The four flag-table summaries of `--quick` (trekreview, orchestrator,
//        command-modes, README) name the brief-conflict rule as the exception
//        to the Pass 3 skip.
//   K3   The orchestrator's 4-pass item 3 names the brief-conflict lowering as
//        the exception to the catalogue reset.
//   ARG  /trekendsession and /trekcontinue Phase 0 and /trekreview Phase 1
//        give $ARGUMENTS to the arg parser (`--stdin`) as the one body line of
//        a quoted heredoc, never as shell words.
//   M8   /trekcontinue and /trekendsession Phase 0 stop on the parser's exit 1
//        with its `errors`, and stop when the parser prints no JSON.
//   M10  /trekendsession Phase 2 reads the label from the parser's `tail`.
//   M13  /trekbrief's research_topics = 0 exit runs Phase 7 with
//        `auto_result: manual`.
//   K2   /trekbrief's Step 6a "Cancel — do manual" row runs Phase 7 with
//        `auto_result: cancelled`, like the sentence after the table.
//   E14  /trekexecute keeps `run_seen` in the progress file (template, field
//        table, Phase 7) and Phase 8 reads it from there, so the resume and
//        multi-session paths report it; Handover 5 lists it as optional.
//   DJ4  /trekexecute's Phase 7.2 step 3 commits only the review's paths git
//        does not ignore, and says an ignored one is left uncommitted.
//   E17a The two /trekresearch wave 2 sentences on outbound queries are pinned
//        exactly (red under the E17a mutation).
//   E17b The deep-research adapter says where wave 2's contrarian findings merge.
//   Da   The README deep-research parenthesis says "when the engine is active".
//   E18a The F9 deep-review and summary-only rows are pinned exactly (red under
//        the E18a mutation).
//   Db   No README line stars security-researcher (red under the Db mutation).
//   M1   No test name in the 4.5a prose file starts with `found in execution:`;
//        the tests f6bdc2d added carry their 4.5a parent tag (red under the
//        M1 mutation, which puts the names back).
//   CHANGELOG (the round's entry in the existing Unreleased section):
//   K4   the siblings entry says the commands read only the two-token
//        `--gates <value>` form and that `--gates=true` is the gates shim's own.
//   M4   the merge-lock entry says a failed git call is reported as
//        `review-not-measured:`, not `review-stale`.
//   M2   ### Fixed records the brief-conflict exception in the four `--quick`
//        summaries.
//   ARG  ### Fixed names the Bash-guard block on a parser heredoc that closes
//        early (R6), and ### Changed says `~` and `$HOME` in the arguments are
//        no longer expanded.
// No static import of a new export: the file must load at be0b631.
// Fix the SOURCE a pin guards, not the pin.
