The pre-commit GSTACK checkpoint guard (architect/tools/gstack-checkpoint-guard.sh in the agent vault) is stricter than the journal convention actually in use. It blocked commits on several review-ready PRs during the #298–#322 integration pass.
Measurement
Counting every *journal*.md under architect/sessions/ against the guard's seven required patterns, as of 2026-07-16:
journals passing guard: 394
journals failing guard: 70
total: 464
So ~15% of real journals cannot host a commit. Per-marker:
missing type: session-journal in 3 journals
missing ## [G] Goal$ in 62 journals
missing ## [S] Structure$ in 66 journals
missing ## [A] Apply Mandates$ in 68 journals
missing ## [T] Trace$ in 66 journals
missing ## [C] Continuous$ in 66 journals
missing ## Checkpoint Ledger$ in 67 journals
Root cause
The guard greps $-anchored exact headings, but the convention permits a descriptive qualifier after the gear tag, and the ledger heading's case is unstable. The canonical forms dominate (~400 journals each), with a long tail of legitimate variants:
402 ## [G] Goal | 6 ## [S] Verified entry state
399 ## [C] Continuous | 5 ## Checkpoint ledger <- case only
399 ## Checkpoint Ledger | 4 ## [A] Plan and success criteria
398 ## [T] Trace | 3 ## [C] Current checkpoint
398 ## [S] Structure | 3 ## [R] Primary-source decision
396 ## [A] Apply Mandates | 2 ## [T] Trace (unit 3)
Note ## Checkpoint ledger vs ## Checkpoint Ledger is a pure case mismatch, and ## [T] Trace (unit 3) fails only because of the $ anchor. Neither indicates a missing section.
Some journals also legitimately lack a gear entirely (e.g. a security-patch lane with two [S] sections and no [T]), so the required-set assumption is itself questionable.
Why this matters
The guard's stated purpose is ensuring work is checkpointed. Rejecting a journal that has a Checkpoint Ledger because the "l" is lowercase does not serve that purpose — it just pushes toward --no-verify, which defeats the guard entirely. That is the real risk here: a guard that misfires 15% of the time trains people to bypass it.
Suggested fix
Relax the patterns to match the convention rather than a subset of it:
- Anchor on the gear tag, not the full heading:
^## \[G\], ^## \[S\], etc. — drop the trailing $ so qualifiers are allowed.
- Make the ledger check case-insensitive:
grep -Eqi '^## checkpoint ledger'.
- Reconsider whether all six gears must be present, given lanes that legitimately omit one.
Then re-run the count above; it should reach ~464/464 without touching a single journal.
Note on this integration pass
Five journals were edited to unblock merges (issues #300/#310/#311/#312/#319 lanes): headings renamed to the canonical marker with the author's original wording preserved as a lead line, plus a [T] Trace section added where genuinely absent recording that session's integration work. No journal content was rewritten or removed, and no commit used --no-verify. Those five are now consistent with the ~400 that already pass, but the guard is what should change — not the remaining 70 journals.
