feat(loop): dependency-aware census selection via the blocking graph - #135
Merged

Conversation
loop-census.sh's ADVANCE selection now skips a planned candidate while any issue it declares "Blocked by" (via cockpit.sh's existing --parse-blocking parser, reused not reimplemented) is still open, emitting a `blocked=<n> by=<N>` census line and picking the next unblocked lowest-numbered candidate instead. Since census re-runs every tick, a blocker closing makes the skipped issue eligible again for free. A "Blocked by" cycle falls back to the lowest-numbered candidate (logged to stderr) instead of wedging the loop. Task-list/parent-child refs (`- [ ] #N`) intentionally do not gate — only the explicit phrase does. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Closes #97
What
loop-census.sh's ADVANCE selector now consults the blocking graph the cockpit already parses, instead of blindly picking the lowest-numberedplanned+module:*issue with no branch.For each otherwise-eligible candidate the census shells out to the existing
cockpit.sh --parse-blockingseam (one parser, never reimplemented) to extract itsBlocked by #Nedges, and skips the candidate while any of those blockers is still OPEN (openness checked against one bulkgh issue list --state openfetch). It emits ablocked=<n> by=<m>line so tick/cockpit output shows why a candidate was passed over, then continues to the next unblocked lowest-numbered candidate.Behavior (acceptance criteria)
Blocked by #Nblocker is never selected for ADVANCE; the skip + reason appear in census output (blocked=<n> by=<m>).Blocked bycycle (A↔B) does not wedge the loop: when the gate leaves no unblocked candidate, it logs a fallback warning to stderr and falls back to the lowest-numbered otherwise-eligible candidate. With zero eligible candidates,advance_readystaysnoneas before.Blocked byedges ONLY — task-list/parent-child- [ ] #Nrefs do NOT gate (trackers stay inbacklog).Scope
