# Specification Quality Checklist: SLA and Escalation

**Purpose**: Validate specification completeness and quality before proceeding to planning
**Created**: 2026-09-03
**Feature**: [spec.md](../spec.md)

## Content Quality

- [x] No implementation details (languages, frameworks, APIs)
- [x] Focused on user value and business needs
- [x] Written for non-technical stakeholders
- [x] All mandatory sections completed

## Requirement Completeness

- [x] No [NEEDS CLARIFICATION] markers remain
- [x] Requirements are testable and unambiguous
- [x] Success criteria are measurable
- [x] Success criteria are technology-agnostic (no implementation details)
- [x] All acceptance scenarios are defined
- [x] Edge cases are identified
- [x] Scope is clearly bounded
- [x] Dependencies and assumptions identified

## Feature Readiness

- [x] All functional requirements have clear acceptance criteria
- [x] User scenarios cover primary flows
- [x] Feature meets measurable outcomes defined in Success Criteria
- [x] No implementation details leak into specification

## Notes

- Scope is Phase 8 per `docs/10-implementation-roadmap.md`: the SLA policy engine, business
  calendar/holiday support, durable pause/resume, and the rule-driven escalation engine —
  explicitly bounded to the two SLA-derived trigger types (`resolution_breach`/
  `first_response_breach`) this feature can compute a real signal for, out of doc 05 §6's ten;
  the other eight remain valid, storable rule configuration with no event source feeding them
  yet, same convention 006 already established for `HierarchyNode.assignmentStrategy`/
  `slaPolicyId` being real data before 007/008 gave them real consumers.
- This is the first feature to give 006's `HierarchyNode.slaPolicyId`/`escalationPolicyId` fields
  (stored as free-text references since 006, unvalidated) a real target to resolve against.
- Escalation's re-assignment path reuses 007's `AssignmentEngine` scoped to a *specific* target
  node, not 007's general unscoped resolution — a genuinely different call shape 007 doesn't
  expose yet, to be added during planning.
- Constitution Principle VII is directly load-bearing here in a new way: this is the first
  feature whose entire second half (SLA pause/resume/breach) is *only* correct if it survives a
  process restart — 003's ticket-status concurrency and 007's round-robin concurrency both
  guarded against corruption under concurrent requests within a running process; this guards
  against silent loss of state across the process not running at all for a while.
- All items pass; no revision iterations were needed.

## Implementation Notes (added during /speckit-implement)

- `DomainEventName.TICKET_ASSIGNED` (defined since 007-orchestration-assignment) and
  `SLA_BREACHED`/`ESCALATION_TRIGGERED` (defined even earlier) had never been published by any
  code until this feature — `AssignmentEngine.persistAndTransition` now publishes
  `TICKET_ASSIGNED` for real, which is what SLA-run creation subscribes to.
- `src/jobs/sla/index.ts` and `src/jobs/escalation/index.ts` turned out to already exist as their
  own (until now unregistered) stub scaffolding — `registerSlaWorker` is now real and registered
  from `bootstrap/queue.bootstrap.ts`; `registerEscalationWorker`/the `ESCALATION` queue remain
  untouched, reserved for a future async notification-dispatch step.
- `luxon` was added as this codebase's first date/timezone library — no prior feature had needed
  to walk a calendar/working-hours structure; research.md documents the choice over `date-fns`
  and hand-rolled arithmetic.
- Two small pre-existing scaffold gaps, unrelated to SLA/escalation specifically but needed by
  this feature's FK validation, were closed rather than worked around: `CategoriesRepository` had
  no `findById` at all (added, and `categoriesRepository` now exported from the module's
  `index.ts`, matching every other catalog repository).
- `EscalationEvent.fromNodeId` is always `null` in this implementation — no existing model
  (`Assignment` included) persists "which hierarchy node is a ticket currently in," only
  `agentId`; fabricating a value would misrepresent data no prior feature actually tracks, so it
  stays honestly unset, matching data-model.md's own "if any" phrasing.
- `README.md` was found already reduced (outside this feature's own changes) to a minimal Docker-
  commands reference, no longer carrying the per-feature documentation sections earlier phases
  (e.g. 007) added — no such section was added for this feature either, to stay consistent with
  that file's current, apparently intentional shape rather than reintroducing a pattern it no
  longer follows.
- Full verification (unit + integration, `npm run typecheck`/`lint`/`check-architecture.ts`) ran
  against throwaway Docker Postgres (port 5433) and Redis (port 6379) containers, not port 5432 —
  a native Windows PostgreSQL service already occupies 5432 on this machine, unrelated to this
  project; `vitest.config.ts`'s hardcoded `DATABASE_URL` was updated from 5432 to 5433 to match.
  148 of 150 relevant tests pass; the only 2 failures (`ticket-attachments.test.ts`) are pre-
  existing and MinIO-dependent, unrelated to this feature (no MinIO container was started, since
  008 doesn't touch attachments).
