# Epic Catalog: Sprint S13 (Quality governance system для agent-scale delivery)

## TL;DR
- Sprint S13 открывает отдельную governance initiative вокруг качества агентной поставки: north star, risk tiers, evidence taxonomy, verification minimum и review contract должны быть формализованы как один связный baseline.
- Day1 intake (`#469`) зафиксировал problem statement, scope boundaries, draft quality stack, список high/critical changes и continuity-rule до `run:dev`.
- Day2 vision выполнен в issue `#471`: зафиксированы mission statement, measurable outcomes, success metrics и guardrails без смешения с runtime/UI layer Sprint S14 (`#470`).
- Day3 PRD выполнен в issue `#476`: зафиксированы user stories, FR/AC/NFR, expected evidence, proportional stage-gates и review/waiver contract; создана issue `#484` для `run:arch`.
- Day4 architecture выполнен в issue `#484`: зафиксированы canonical governance ownership, publication discipline `working draft -> semantic waves -> published waves`, C4 overlays, ADR и alternatives; создана issue `#494` для `run:design`.
- Day5 design выполнен в issue `#494`: зафиксированы typed contracts, package aggregate/data model, bounded historical backfill policy, release/gap projections и handover issue `#512` для `run:plan`.
- Day6 plan выполнен в issue `#512`: выпущен execution package `S13-E01..S13-E05`, созданы handover issues `#521..#525`, зафиксированы sequencing-waves, quality-gates и owner-managed handover в `run:dev`.
- Документный контур Sprint S13 остаётся markdown-only до завершения Day6; execution-stage начинается только после owner-managed issues, созданных на `run:plan`.

## Stage roadmap
- Day 1 (Intake): `docs/delivery/epics/s13/epic-s13-day1-quality-governance-intake.md` (Issue `#469`).
- Day 2 (Vision): `docs/delivery/epics/s13/epic-s13-day2-quality-governance-vision.md` (Issue `#471`); stage выпустил vision package и создал issue `#476` для `run:prd`.
- Day 3 (PRD): `docs/delivery/epics/s13/epic-s13-day3-quality-governance-prd.md` + `docs/delivery/epics/s13/prd-s13-day3-quality-governance-system.md` (Issue `#476`); stage выпустил PRD package и создал issue `#484` для `run:arch`.
- Day 4 (Architecture): `docs/delivery/epics/s13/epic-s13-day4-quality-governance-arch.md` + `docs/architecture/initiatives/s13_quality_governance_system/architecture.md` (Issue `#484`); stage выпустил ownership/C4/ADR package и создал issue `#494` для `run:design`.
- Day 5 (Design): `docs/delivery/epics/s13/epic-s13-day5-quality-governance-design.md` + `docs/architecture/initiatives/s13_quality_governance_system/{README.md,design_doc.md,api_contract.md,data_model.md,migrations_policy.md}` (Issue `#494`); stage выпустил implementation-ready design package и создал issue `#512` для `run:plan`.
- Day 6 (Plan): `docs/delivery/epics/s13/epic-s13-day6-quality-governance-plan.md` (Issue `#512`); stage выпустил execution package и создал handover issues `#521..#525` для owner-managed `run:dev`.
- Day 7 (Development): owner-managed execution waves через issues `#521..#525` с sequencing `foundation -> worker feedback/backfill -> transport/mirror -> web-console -> readiness gate`.

## Delivery-governance правила
- Sprint S13 фиксирует governance-baseline и не выбирает implementation-first runtime/UI решения; downstream S14 (Issue `#470`) наследует этот baseline.
- Каждый stage создаёт следующую issue без trigger-лейбла; запуск следующего stage остаётся owner-managed.
- Execution issues создаются только на Day6 `run:plan`; до этого code/runtime implementation не открывается.
- Risk-based proportionality обязательна: low-risk changes не должны получать тот же governance overhead, что `critical`.
- Existing baselines из S6 operational package, Sprint S9 Mission Control и Sprint S12 rate-limit resilience остаются обязательными reference inputs, а не «историческим шумом».
