…dler) Closes the broken composes_with edge surfaced by audit-backlog-items.ts on origin/main: B-0460's frontmatter listed `composes_with: [..., B-0461]` but B-0461 didn't exist as a file. The reference existed as a placeholder in two rows (B-0449 design pass + B-0460 sibling table) explicitly naming "B-0461 — missed-substrate-cascade handler (slice 5.3)". This commit makes it real. The row follows the shape of sibling B-0459 (infinite-backlog-nudge handler) and B-0460 (work-assignment handler) — they form the three slice-5.x subscriber-handler rows per B-0449's Option C design. Scope: stub handler that reads + logs missed-substrate-cascade envelopes and reports drift to the tick output. Does NOT auto-open recovery PR — that's B-0503 (openRecoveryPR core) + B-0504 (wire into pollOnce). Audit verification before/after: Before: ** Broken composes_with edges: 1 ** (B-0460 → missing B-0461) After: ** Broken composes_with edges: 0 ** This is the kind of small-atomic finding audit-backlog-items.ts surfaces that's worth fixing inline rather than batching — single broken edge, single new row, audit goes clean.

…es_with edge (#3256) * shard(tick): 2123Z — audit-driven: file B-0461 to close broken composes_with edge Tick output: - PR #3253 (feat(b-0461)): authors the missing B-0442 slice 5.3 row (missed-substrate-cascade handler) that B-0460's composes_with referenced but didn't exist. Audit verification: 1 → 0 broken composes_with edges. Auto-merge armed. - This shard. The slice-5 subscriber-handler row family is now complete: - B-0459 (infinite-backlog-nudge) — already filed - B-0460 (work-assignment) — already filed - B-0461 (missed-substrate-cascade) — filed this tick Audit-driven workflow observed: new audit class (duplicate-IDs, #3250) also runs the existing audit classes; the broken-composes_with finding surfaced was small + atomic + worth fixing inline. Cousin pattern to the three-step propagation from tick 2113Z: - Review-time catch → fix → mechanization (Copilot-driven) - Run-time audit → finding → fix (audit-driven) Both produce durable factory defenses. Prior-tick PRs merged this batch: - #3249 (shard 2108Z + MD032 fix) MERGED as f74e577 - #3250 (duplicate-ID audit class) MERGED as 47eb547 - #3252 (shard 2119Z) MERGED as 330392f Session tally: 21 merged + 2 wait-ci. Cron sentinel 12fb713e armed; recurring. Co-Authored-By: Claude <noreply@anthropic.com> * fix(pr3256): rewrite `+ ...` continuation as prose per Copilot review Copilot caught: line 45 had a wrapped continuation starting with `+` inside a `-` bullet. markdownlint parses that as a nested list item using a different bullet style — exact CI-breaking pattern called out in the repo guideline. Fix: rewrote `... + dependency chain + composes_with + pre-start checklist)` into prose ("covering frontmatter, AC, scope clarification, dependency chain, composes_with, and pre-start checklist") so no continuation line starts with `+` or any list-bullet character. markdownlint-cli2 now clean. Composes with the tick 2119Z MD032 pattern (Section: + blank + list) and tick 2046Z plist-exclusion: this is another instance of "tick shards quoting structured content can accidentally trip lint rules unless we reproduce the structure verbatim or rewrite as prose."

The audit drove the gap-detection; this PR closes the gap.
Scope (stub handler)
missed-substrate-cascadeenvelopes from the bus dirWhy P1
The audit-driven completeness of the slice-5 row family unblocks future implementation of all three subscriber handlers as a coherent set. Without B-0461, edge references in B-0460 are ambiguous.
