fix: round 9 of the release review of 6.3.0, for 6.3.1

Round 9 (0f400d3..a10018f, WARN: 0 BLOCKER, 12 MAJOR): seven findings and
three brief notes, by operator choice. Each finding began with a test that
failed on a10018f on its assertion; suite 2230 (2228/0/2).

- A check refused for its comment (a quote, $, backtick or backslash) keeps
  its command and its reason, and every reader refuses it out loud: a nested
  ## Verification bullet stays a criterion (PLAN_VERIFICATION_NOT_RUNNABLE)
  and a brief SC warns (BRIEF_SC_NOT_RUNNABLE). It was folded into a
  sub-point or read as prose, a regression from a10018f. Readers that took a
  command as runnable (the end-to-end lists) skip a refused one.
- The verdict gate reads the last fenced block's info string and body from
  one reading, and exits 2 unless the info string is exactly json: a last
  block opened as ```json {x} held a BLOCKER the gate passed with exit 0
  (also in 6.3.0). A last block never closed is exit 2 too.
- One fence reader (findings-schema fencedBlocks) for the gate and every
  trailing-json reader: a fence closes only on a run at least as long as its
  opener, as in Markdown, so a four-backtick example of a json block is one
  block; CRLF and an indented fence read alike in the gate and the readers.
- Files: a description runs on past a comma and onto the next line until a
  new entry starts (a list item on a new line, or a backticked path), and a
  plain path followed by a colon starts its description. Measured over all
  939 Files: fields in the .md files under the marketplace and the test repo
  (560 of them in the 48 plan.md files outside worktrees): 0 read
  differently, tests-only changed in 0.
- The test lock compares --cmd by its words, so other blanks between the
  same words are the step's command.
- release-check decides "two files" on real paths: one review.md reached
  through a symlinked --repo is one file.
- Brief notes: red proof's stopped control run has its own test (green at
  once, red with the branch deleted); the two tests that assumed jest is not
  installed run with a PATH that finds only git (red on a10018f with a jest
  on PATH, green now); the Files: reader's doc states the measured counts
  (520 fields in 48 plan files at rounds 7-8, not "182 plans"; 560 now).

Not in this round (operator 2026-10-11): a144e9ce, 1dc2e785, dc3a467e,
2fa88853, 26873fa5.
