Add src/build_cache_pruner.py — a background daemon thread modelled 1:1 on
src/disk_watchdog.py that periodically runs STRICTLY `docker builder prune -f
--filter until=<until>` (BuildKit GC) on the HOST over ssh. It is the "second
half" of the disk-watchdog (ORCH-063): the watchdog signals, the pruner cleans.
Removes the root cause of the 07.06.2026 incident (build cache ~11GB -> disk
100% -> whole self-hosting pipeline down) automatically, без оператора.
ADR-001 (Variant A): host-over-ssh, same channel as image_freshness/self_deploy
(no docker CLI in the image). Touches ONLY the build cache — no image/system
prune, no image/container removal, never restarts the docker daemon or the prod
container (self-hosting safety). No ssh target -> tick is a no-op.
- src/config.py: ORCH_BUILD_CACHE_PRUNE_* flags + defensive validators
(interval/timeout >0, until ~ ^\d+[smhdw]?$, notify_min_gb >=0 -> safe default).
- src/main.py: start last (after disk_watchdog) / stop first in lifespan;
additive read-only build_cache_prune block in GET /queue.
- never-raise on two levels (per-command + per-tick); kill-switch
ORCH_BUILD_CACHE_PRUNE_ENABLED (false -> daemon does not start, 1:1 as before).
- STAGE_TRANSITIONS / QG_CHECKS / check_* / _parse_* / DB schema UNCHANGED;
last-run/last-result is in-memory (no migration).
- tests/test_build_cache_pruner.py: TC-01..TC-12 (23 cases, docker fully mocked).
- .env.example + CHANGELOG.md updated; INFRA.md / architecture docs already
carry the component (architecture stage).

Adds src/disk_watchdog.py — a background daemon thread modelled on
reconciler/job_reaper that measures host-FS fill via the mounted bind-paths
(/repos, /app/data) with shutil.disk_usage and Telegram-alerts the operator at
>= threshold (default 85%). The missing proactive signal: on 07.06.2026 the
mva154 host disk silently hit 100% and stalled the whole self-hosting pipeline.
- Pure decide_action(used_pct, threshold, prev, now, realert_s): alert on
crossing up, cooldown re-alert, single recovery below threshold (unit-tested
without a thread/timer; clock injected).
- measure_paths: shutil.disk_usage per path, dedup by st_dev, per-path
never-raise (a broken path never fails the tick).
- Config flags ORCH_DISK_MONITOR_* with defensive validation (threshold 1..100,
positive intervals -> default + warning). Kill-switch -> daemon does not start.
- Additive disk_monitor block in GET /queue; start/stop in main.lifespan.
- never-raise (per-path/per-tick/per-send); STAGE_TRANSITIONS/QG_CHECKS/check_*/
DB schema untouched, no migration (anti-spam state in-memory).
Tests: tests/test_disk_watchdog.py (TC-01..TC-12, 18 cases); full suite green
(1296). Docs: INFRA.md, .env.example, CHANGELOG.md (architecture/README.md +

Lift the two HUMAN gates that block an autonomous batch run (epic ORCH-088):
the BRD gate (analysis: manual Approved) and the prod-deploy gate (deploy
Phase A: manual Confirm Deploy, ORCH-059). Selective (a Plane label on the
issue), declarative, reversible, and WITHOUT touching a single technical check.
Additive, mirroring the conditional sub-gates (ORCH-035/043/058/088): leaf
src/labels.py (never-raise) + two point insertions + config flags.
STAGE_TRANSITIONS / QG_CHECKS / check_* / DB schema are NOT touched.
- autoApprove: врезка in _handle_analysis_approved_flow (files_ok branch) ->
set_issue_approved + log/Telegram/Plane-comment + advance_stage(
finished_agent=None) — the SAME path a human Approved takes (approved-via-
status -> analysis->architecture + mark_brd_review_ended). No duplicated
transition logic; re-entrancy safe.
- autoDeploy: врезка in _handle_self_deploy_phase_a after advance to deploy +
clear_state -> log/Telegram/Plane-comment + _handle_self_deploy_phase_b
(INITIATED marker, Deploying, finalizer). Only the indicative human steps are
skipped. BR-5 holds structurally: Phase A is reached only after the green edge
sub-gates, so autoDeploy can never deploy a broken build.
- plane_sync: fetch_issue_labels (None on error != []), get_project_labels
({normalized_name->uuid}, TTL cache, ambiguity sentinel), set_issue_approved.
- config flags: auto_label_enabled (kill-switch), auto_approve_label/
auto_deploy_label, auto_label_repos (empty -> self-hosting only),
auto_label_states_ttl_s. applies() (local) checked FIRST; has_label (network)
only when applies==True -> zero network / zero regression when disabled (AC-8).
- Fail-safe (never auto on doubt), transparency via log+Telegram+Plane+card,
read-only auto_labels block in GET /queue.
- Tests TC-01..TC-26 across 7 modules; docs (CLAUDE.md, architecture README,
CHANGELOG) updated in the same PR.

Этап 1 (serial e2e) пакетного автономного режима. Новая задача репо не входит
в analysis (analyst-job не выбирается, ветка не режется), пока в репо есть более
ранняя незавершённая задача (FIFO, t2.id < jobs.task_id) ИЛИ репо заморожен.
- src/serial_gate.py — новый leaf (never-raise): build_claim_clause (fail-OPEN),
is_repo_frozen (fail-CLOSED), set/clear_repo_freeze, serial_gate_applies, snapshot.
- src/db.py — идемпотентная миграция repo_freeze + serial_gate-фрагмент в claim_next_job.
- src/webhooks/plane.py + src/agents/launcher.py — отложенный срез ветки: start_pipeline
не создаёт Gitea-ветку/docs для применимого репо; релокация в _materialize_deferred_branch
на момент claim analyst-job (база = свежий origin/main с кодом предшественника, AC-6).
- src/stage_engine.py — post-deploy DEGRADED → durable per-repo freeze + Telegram-алерт.
- src/main.py — блок serial_gate в GET /queue + POST /serial-gate/unfreeze.
- src/config.py — serial_gate_enabled / serial_gate_repos / serial_gate_freeze_enabled.
FIFO-уточнение реализации (FR-2): ADR-001 D1 фиксировал t2.id != jobs.task_id; при !=
пакет одновременно созданных свежих задач взаимно блокировался бы (дедлок). t2.id <
jobs.task_id допускает самую раннюю задачу и сериализует остальные, сохраняя AC-1/R-7.
STAGE_TRANSITIONS / QG_CHECKS / check_* — без изменений. Аддитивно, под kill-switch,
never-raise, restart-safe; при выключенном флаге — нулевая регрессия (enduro не затронут).
Тесты: TC-01..TC-22 (test_serial_gate*.py + test_queue_endpoint.py); полный прогон 1114 зелёных.

Level A — merge/deploy serialization within one repo: reuse the existing
ORCH-043/065 merge-lease (no new mechanism); the only new logic is an
unconditional pre-merge rebase in check_branch_mergeable — under the held
lease, auto_rebase_onto_main is ALWAYS called when premerge_rebase_always
(default True), not just when the branch is behind. No-op on an up-to-date
branch (rebase keeps HEAD, force-with-lease -> "Everything up-to-date", CI
not triggered). Kill-switch off -> ORCH-043 behaviour 1:1.
Level B — declarative task dependencies: additive job_deps table
(CREATE ... IF NOT EXISTS, no live-DB migration); claim_next_job gate
(NOT EXISTS) defers a job whose depends-on tasks are not yet 'done' without
occupying a max_concurrency slot; inert on empty job_deps -> zero regression.
New leaf src/task_deps.py (never-raise): is_task_ready (fail-open), DFS cycle
detection + Blocked/alert, declare/ingest_plane_relations (db source never
hits the network on the hot path), snapshot. Telegram waiting-line, /queue
observability, reconciler skip + cycle backstop, reaper untouched.
Invariants unchanged: STAGE_TRANSITIONS, QG_CHECKS registry (dep gate is a
claim_next_job врезка, not a registered QG), DB schema of existing tables,
HTTP endpoints; non-self repos remain a no-op on empty deps/scope.
Flags: ORCH_PREMERGE_REBASE_ALWAYS, ORCH_TASK_DEPS_ENABLED, ORCH_TASK_DEPS_SOURCE.
Docs: docs/architecture/README.md, CLAUDE.md, .env.example, CHANGELOG.md,
adr-0015. Tests: tests/test_orch026_*.py (64 tests); full suite 991 green.

Closes the "zombie jobs" incident class: job status was set only inside
the live launcher process, so a process death left jobs.status='running'
forever; at max_concurrency=1 one zombie blocked ALL projects' queue
(self-hosting risk). Adds a background daemon (src/job_reaper.py) with
three-tier liveness (dead-pid streak / known exit_code / max-running
backstop) whose only mutating write is an atomic terminal flip guarded by
WHERE status='running' (no double-process). For exit0 the canonical QG is
the source of truth via gate-driven advance, not "exit0".
Also proactively reclaims stale merge-lease (dead pid OR TTL) via file
delete only (no git ops), and makes merge finalization idempotent
(pr_already_merged guard + up-to-date short-circuit on re-drive).
New jobs.pid column via idempotent _ensure_column (no migration); pid
stamped in launcher._spawn after Popen. Reaper start/stop in lifespan;
"reaper" snapshot in GET /queue. Kill-switches: ORCH_REAPER_ENABLED,
ORCH_REAPER_INTERVAL_S, ORCH_REAPER_DEAD_TICKS, ORCH_REAPER_MAX_RUNNING_S,
ORCH_LEASE_RECLAIM_ENABLED.
Invariants unchanged (AC-13): STAGE_TRANSITIONS, QG_CHECKS registry,
check_branch_mergeable signature/behaviour, BUG-8 rollback, hook exit
codes. restart-safe, never-raise per unit of background work.
Docs: docs/architecture/README.md, CHANGELOG.md, .env.example.
Tests: tests/test_job_reaper.py, tests/test_merge_lease_reclaim.py,
tests/test_merge_gate.py (TC-16), tests/test_merge_gate_race.py (TC-17),

Extend pipeline responsibility past deploy->done: after the terminal
transition for an applicable repo, arm a ~15min observation window that
probes prod and reacts to a degradation the restart-time health-check
missed ("green deploy, red prod").
- src/post_deploy.py: new leaf module (config + lazy qg/db only).
Sentinel-file restart-safe state (.post-deploy-state-<repo>/<wi>/),
no DB migration. probe_signals/classify/decide_action/run_rollback,
all never-raise.
- Reserved-agent job `post-deploy-monitor` (no-LLM, Variant B, calque of
deploy-finalizer): self-requeues each tick via enqueue_job.
- Deterministic classify: DEGRADED iff >= fail_threshold consecutive
health failures OR window 5xx ratio > 5xx_threshold; fail-safe HEALTHY.
- Self-hosting invariant (BR-5/AC-8): a tick NEVER restarts the prod
orchestrator container -> orchestrator is ALWAYS ALERT_ONLY.
- Conditionality (ORCH-35/36/43/58): kill-switch + CSV repos, empty ->
self-hosting only.
- QG_CHECKS / STAGE_TRANSITIONS / schema unchanged (AC-12).
- Docs: CHANGELOG, CLAUDE artefact list (16-post-deploy-log.md),
architecture README, .env.example (ORCH_POST_DEPLOY_*).

Конвейер продвигается только входящими webhook; потерянное событие (502 на
ребилде, отсутствие ретраев у Plane/Gitea, неразрезолвленный sha→branch)
оставляет задачу молча застрявшей (класс инцидента ORCH-044). Новый фоновый
daemon-поток src/reconciler.py (паттерн queue_worker) доигрывает пропущенный
переход через те же штатные гейты/обработчики, что и webhook:
- F-1 gate-side: для задач stage≠done, без активного job и age(updated_at) ≥
grace_for_stage(stage) — read-only пред-оценка канонического QG; зелёный →
stage_engine.advance_stage(..., finished_agent=None); красный → тишина (спам
нотификаций структурно невозможен). analysis F-1 не трогает (человеческий гейт).
- F-2 plane-side: опрос Plane API per-project (plane_sync.list_issues_by_state,
курсорная пагинация, never-raise) → реплей In Progress/Approved/Rejected через
существующие handle_status_start/handle_verdict (async из sync-потока, asyncio.run).
- F-3: усиление sha→branch в handle_ci_status — БД-fallback по единственной
development-задаче repo (неоднозначность → не резолвим), debug→info.
- Анти-дубль на создании (db.create_task_atomic под process-wide Lock): гонка
reconcile↔webhook не плодит второй task/branch/worktree/analyst-job (AC-4).
- F-4 observability: лог-строка разблокировки + Telegram + блок reconcile в /queue.
Старт/стоп в main.lifespan (после worker.start() / перед worker.stop()),
restart-safe, never-raise на единицу работы. Kill-switches ORCH_RECONCILE_ENABLED
/ ORCH_RECONCILE_PLANE_ENABLED + grace-настройки. Схема БД и реестры
STAGE_TRANSITIONS/QG_CHECKS не менялись.
Тесты: test_reconciler.py, test_reconciler_plane.py, test_gitea_sha_resolve.py,
test_config.py (33 новых, 563 всего зелёные). Документация обновлена (golden source):
architecture/README.md, INFRA.md, README.md, CHANGELOG.md, adr-0007 → accepted.

queue_worker.QueueWorker drains the queue respecting max_concurrency. main.py
lifespan: queue-recovery (requeue running jobs) after M-1 orphan-recovery, starts
worker and stops it on shutdown. New GET /queue endpoint (counts + recent jobs).
