The parser's turn.completed/turn.failed/disconnect semantics were pinned
by shape only — now the python block is extracted from both RENDERED
sections and run against synthetic event streams (tokens line, FAILED +
not-a-disconnect, silence -> disconnect warning, SESSION_ID echo), with
byte-equivalence safety pins on the bash double-quote extraction. The
fence scanner also gains CommonMark opener-length tracking: a 4-backtick
fence wrapping a 3-backtick example no longer false-positives, with a
self-test.

Three defects in the codex skill sections:
- The resumed-session bash block never closed its fence; every fenced region
after it inverted (prose rendered as code, the synthesis-recommendation tail
rendered inert). A repo-wide fence-pairing test now scans every generated
SKILL.md and sections/*.md with a CommonMark-faithful state machine (an
info-string opener inside a fence is literal content — nested template
examples in document-generate/make-pdf stay legal; a file ending inside a
fence fails).
- The JSONL parsers had no turn.failed branch: a turn that STATED its failure
was reported as 'possible mid-stream disconnect'. Challenge and consult now
print the event's error and run a three-way completeness check (failed-with-
reason / silent-disconnect / ok); consult previously had no completeness
check at all.
- ${PIPESTATUS[0]} is empty under zsh, so hang detection never fired and
every clean run printed a spurious '[codex exit ]'. All three capture sites
use ${PIPESTATUS[0]:-${pipestatus[1]}}, pinned statically and EXECUTED
under real bash and zsh in the new test. Expect a step-change in
codex_timeout telemetry — the counter starts firing for zsh users.
Receipt: the portability pin fails on a v1.77.0.0 scratch worktree; the fence
fix is structural (17 → 18 fence lines, tail no longer inside a block).
