Orchestrator: per-turn liveness — heartbeat thread, per-turn BaseException capture, whole-turn cap wrapping stream consumption; verifier I2.8

Fixture regen machinery + I2.6 verdict flip on the 142625 fixture (unblocks I2.6 → gating promotion)

Orchestrator: bound `empty_turn_detected` retries — fail-fast on byte-identical retry input; hard-cap at N=2 per (agent, phase, round)

Parser: consolidate every specific-literal-heading anchor onto one tolerant `section_heading_re` primitive in markers.py

Refactor: stop losing cycle-start anchor events on the first `--push-to-main` resync by adding a `queue_state flush` subcommand and wiring `/dev-next` to call it at step 12

Spec dashboard renders the `disposition` field on each spec card so backfilled-as-`archive` carve-outs are visually distinguishable from `disposition: ship` queue heads

Refactor: split `backfill_disposition.py` reason-text by spec-ID era so post-0229 specs no longer carry the misleading `Pre-spec-0229 carve-out` marker

Refactor: amend spec 0229.1 §3 acceptance criterion to scope the post-backfill validator claim to disposition-class checks only, aligning the spec text with the test that ships (`test_no_existing_spec_fails_specifically_on_disposition`)

Refactor: add `disposition:` + `disposition_reason:` placeholders to all five spec templates so verbatim-template authors don't trip the spec 0229.1 validator gate

Verifier I2.6 — STATUS-RAISED-array event cross-check (reporting)

Parser heading tolerance and graceful repair fallback

Reconciler: configurable prefix-skip list (default `cowork/`) treats out-of-tree citations as informational, eliminating the spurious exit-3 class for specs citing external Cowork briefs

Enforce addressee-obligation: emit ProtocolViolation on AGREED with open addressed-at-me items; surface those items in closeout requests; promote verifier I2.4 from reporting to gating; codify the carve-out-disposition convention

Emit ProtocolViolation when an op is silently dropped for a state-machine reason; promote verifier invariant I4.4 from reporting to gating

Refactor: reclassify 4 contract-amending specs (0137 / 0140 / 0218 / 0219) from `bug` + add CLAUDE.md contract-change process rule

Add lifecycle-trace verifier asserting the 0114 unified contract

Fix: CLI registers SIGTERM/SIGHUP/SIGINT cancel handlers so the 0222 tombstone fires on raw signal kills

Fix: Phase 4 turn cards drop Issues + Comments per-round Δ chips (Q→D→I→C contract violated)

Fix: liveness tombstone (BaseException + finally-fallback) and remove asymmetric stdout streaming

Fix: Document modal labels the converged/final draft tab "Output" instead of "Content"

In-app Changelog auto-generated from CHANGELOG.md

Fix: §3.2 section-delta drafter contract — reviewer/validator collision, heading-mismatch corruption, REPLACE_SECTION budget overrun, mid-phase resume waste

Refactor: /dev-next step 21 — delegate fly deploy to .github/workflows/deploy.yml (eliminate local-vs-GHA deploy race)

Refactor: /dev-next step 19/20/24 — eliminate worktree cross-conflict on main checkout (push-via-plumbing for handoff + archive, queue worktree never holds main)

Fix: CollapsibleSection bodies stay hidden when open due to legacy how-it-works CSS bleed

Fix: provider chip dim in critique — promote tone-claude/gpt override into the base Chip primitive

Tests: canonicalize the JSX-loaded-via-babel test doctrine (Playwright harness or source-pattern as the documented project pattern)

Tests: pixel + structural fidelity check of the live dashboard against `dashboard-redesign-v3-horizontal.html`

Fix: authoring funnel DRAFTS bucket only counts promoted drafts, omits current backlog under `specs/drafts/`

Fix: bootstrap timeline shows `—` for completed-stage durations after `/api/data` refresh

Fix: All-Runs reports `running` for runs that died days ago — add time-based liveness check + new `abandoned` lifecycle status

Fix: Consumption card V2 anatomy — split combined Total tokens bar into total-input + total-output, add output totals block, move cache-savings line

Fix: critique-card body redundancies (verdict row, bottom anchor, seen-row) + mandate side-by-side parity grid in PR

Fix: three-section Input panel reveals empty body — drop inner per-piece default-collapse so one click on outer chevron shows content

Drain deferrals — pulse-info dot, .tab-group-solid rename, segment counts, item-card head/lifecycle/sources/collapse, upstream [object Object] fix

Fix: critique cards render literal ** markdown and re-show cryptic compound IDs
