chore: add kiro spec-driven tooling and steering docs

Add the Kiro-style agentic SDLC tooling used to drive this project: the
.opencode/skills/kiro-* skill set (discovery, spec init/requirements/design/
tasks, validation, implementation, review, steering), the .kiro/settings
templates, and AGENTS.md describing the workflow. Update the spec docs
(assessment/design/requirements/tasks) to current state.

Scope tests/test_opencode_skills.py to the project's own openultrasast-*
skills so the third-party kiro-* tooling (which uses a different frontmatter
convention) no longer breaks the frontmatter check.

# API Standards
[Purpose: consistent API patterns for naming, structure, auth, versioning, and errors]
## Philosophy
- Prefer predictable, resource-oriented design
- Be explicit in contracts; minimize breaking changes
- Secure by default (auth first, least privilege)
## Endpoint Pattern
```
/{version}/{resource}[/{id}][/{sub-resource}]
```
Examples:
- `/api/v1/users`
- `/api/v1/users/:id`
- `/api/v1/users/:id/posts`
HTTP verbs:
- GET (read, safe, idempotent)
- POST (create)
- PUT/PATCH (update)
- DELETE (remove, idempotent)
## Request/Response
Request (typical):
```json
{ "data": { ... }, "metadata": { "requestId": "..." } }
```
Success:
```json
{ "data": { ... }, "meta": { "timestamp": "...", "version": "..." } }
```
Error:
```json
{ "error": { "code": "ERROR_CODE", "message": "...", "field": "optional" } }
```
(See error-handling for rules.)
## Status Codes (pattern)
- 2xx: Success (200 read, 201 create, 204 delete)
- 4xx: Client issues (400 validation, 401/403 auth, 404 missing)
- 5xx: Server issues (500 generic, 503 unavailable)
Choose the status that best reflects the outcome.
## Authentication
- Credentials in standard location
```
Authorization: Bearer {token}
```
- Reject unauthenticated before business logic
## Versioning
- Version via URL/header/media-type
- Breaking change → new version
- Non-breaking → same version
- Provide deprecation window and comms
## Pagination/Filtering (if applicable)
- Pagination: `page`, `pageSize` or cursor-based
- Filtering: explicit query params
- Sorting: `sort=field:asc|desc`
Return pagination metadata in `meta`.

# Authentication & Authorization Standards
[Purpose: unify auth model, token/session lifecycle, permission checks, and security]
## Philosophy
- Clear separation: authentication (who) vs authorization (what)
- Secure by default: least privilege, fail closed, short-lived tokens
- UX-aware: friction where risk is high, smooth otherwise
## Authentication
### Method (choose + rationale)
- Options: JWT, Session, OAuth2, hybrid
- Choice: [our method] because [reason]
### Flow (high-level)
```
1) User proves identity (credentials or provider)
2) Server verifies and issues token/session
3) Client sends token per request
4) Server verifies token and proceeds
```
### Token/Session Lifecycle
- Storage: httpOnly cookie or Authorization header
- Expiration: short-lived access, longer refresh (if used)
- Refresh: rotate tokens; respect revocation
- Revocation: blacklist/rotate on logout/compromise
### Security Pattern
- Enforce TLS; never expose tokens to JS when avoidable
- Bind token to audience/issuer; include minimal claims
- Consider device binding and IP/risk checks for sensitive actions
## Authorization
### Permission Model
- Choose one: RBAC / ABAC / ownership-based / hybrid
- Define roles/attributes centrally; avoid hardcoding across codebase
### Checks (where to enforce)
- Route/middleware: coarse-grained gate
- Domain/service: fine-grained decisions
- UI: conditional rendering (no security reliance)
Example pattern:
```typescript
requirePermission('resource:action'); // route
if (!user.can('resource:action')) throw ForbiddenError(); // domain
```
### Ownership
- Pattern: owner OR privileged role can act
- Verify on entity boundary before mutation
## Passwords & MFA
- Passwords: strong policy, hashed (bcrypt/argon2), never plaintext
- Reset: time-limited token, single-use, notify user
- MFA: step-up for risky operations (policy-driven)
## API-to-API Auth
- Use API keys or OAuth client credentials
- Scope keys minimally; rotate and audit usage
- Rate limit by identity (user/key)

# Database Standards
[Purpose: guide schema design, queries, migrations, and integrity]
## Philosophy
- Model the domain first; optimize after correctness
- Prefer explicit constraints; let database enforce invariants
- Query only what you need; measure before optimizing
## Naming & Types
- Tables: `snake_case`, plural (`users`, `order_items`)
- Columns: `snake_case` (`created_at`, `user_id`)
- FKs: `{table}_id` referencing `{table}.id`
- Types: timezone-aware timestamps; strong IDs; precise money types
## Relationships
- 1:N: FK in child
- N:N: join table with compound key
- 1:1: FK + UNIQUE
## Migrations
- Immutable migrations; always add rollback
- Small, focused steps; test on non-prod first
- Naming: `{seq}_{action}_{object}` (e.g., `002_add_email_index`)
## Query Patterns
- ORM for simple CRUD and safety; raw SQL for complex/perf-critical
- Avoid N+1 (eager load/batching); paginate large sets
- Index FKs and frequently filtered/sorted columns
## Connection & Transactions
- Use pooling (size/timeouts based on workload)
- One connection per unit of work; close/return promptly
- Wrap multi-step changes in transactions
## Data Integrity
- Use NOT NULL/UNIQUE/CHECK/FK constraints
- Validate at DB when appropriate (defense in depth)
- Prefer generated columns for consistent derivations
## Backup & Recovery
- Regular backups with retention; test restores
- Document RPO/RTO targets; monitor backup jobs

# Deployment Standards
[Purpose: safe, repeatable releases with clear environment and pipeline patterns]
## Philosophy
- Automate; test before deploy; verify after deploy
- Prefer incremental rollout with fast rollback
- Production changes must be observable and reversible
## Environments
- Dev: fast iteration; debugging enabled
- Staging: mirrors prod; release validation
- Prod: hardened; monitored; least privilege
## CI/CD Flow
```
Code → Test → Build → Scan → Deploy (staged) → Verify
```
Principles:
- Fail fast on tests/scans; block deploy
- Artifact builds are reproducible (lockfiles, pinned versions)
- Manual approval for prod; auditable trail
## Deployment Strategies
- Rolling: gradual instance replacement
- Blue-Green: switch traffic between two pools
- Canary: small % users first, expand on health
Choose per risk profile; document default.
## Zero-Downtime & Migrations
- Health checks gate traffic; graceful shutdown
- Backwards-compatible DB changes during rollout
- Separate migration step; test rollback paths
## Rollback
- Keep previous version ready; automate revert
- Rollback faster than fix-forward; document triggers
## Configuration & Secrets
- 12-factor config via env; never commit secrets
- Secret manager; rotate; least privilege; audit access
- Validate required env vars at startup
## Health & Monitoring
- Endpoints: `/health`, `/health/live`, `/health/ready`
- Monitor latency, error rate, throughput, saturation
- Alerts on SLO breaches/spikes; tune to avoid fatigue
## Incident Response & DR
- Standard playbook: detect → assess → mitigate → communicate → resolve → post-mortem
- Backups with retention; test restore; defined RPO/RTO

# Error Handling Standards
[Purpose: unify how errors are classified, shaped, propagated, logged, and monitored]
## Philosophy
- Fail fast where possible; degrade gracefully at system boundaries
- Consistent error shape across the stack (human + machine readable)
- Handle known errors close to source; surface unknowns to a global handler
## Classification (decide handling by source)
- Client: Input/validation/user action issues → 4xx
- Server: System failures/unexpected exceptions → 5xx
- Business: Rule/state violations → 4xx (e.g., 409)
- External: 3rd-party/network failures → map to 5xx or 4xx with context
## Error Shape (single canonical format)
```json
{
"error": {
"code": "ERROR_CODE",
"message": "Human-readable message",
"requestId": "trace-id",
"timestamp": "ISO-8601"
}
}
```
Principles: stable code enums, no secrets, include trace info.
## Propagation (where to convert)
- API layer: Convert domain errors → HTTP status + canonical body
- Service layer: Throw typed business errors, avoid stringly-typed errors
- Data/external layer: Wrap provider errors with safe, actionable codes
- Unknown errors: Bubble to global handler → 500 + generic message
Example pattern:
```typescript
try { return await useCase(); }
catch (e) {
if (e instanceof BusinessError) return respondMapped(e);
logError(e); return respondInternal();
}
```
## Logging (context over noise)
Log: operation, userId (if available), code, message, stack, requestId, minimal context.
Do not log: passwords, tokens, secrets, full PII, full bodies with sensitive data.
Levels: ERROR (failures), WARN (recoverable/edge), INFO (key events), DEBUG (diagnostics).
## Retry (only when safe)
Retry when: network/timeouts/transient 5xx AND operation is idempotent.
Do not retry: 4xx, business errors, non-idempotent flows.
Strategy: exponential backoff + jitter, capped attempts; require idempotency keys.
## Monitoring & Health
Track: error rates by code/category, latency, saturation; alert on spikes/SLI breaches.
Expose health: `/health` (live), `/health/ready` (ready). Link errors to traces.

# Security Standards
[Purpose: define security posture with patterns for validation, authz, secrets, and data]
## Philosophy
- Defense in depth; least privilege; secure by default; fail closed
- Validate at boundaries; sanitize for context; never trust input
- Separate authentication (who) and authorization (what)
## Input & Output
- Validate at API boundaries and UI forms; enforce types and constraints
- Sanitize/escape based on destination (HTML, SQL, shell, logs)
- Prefer allow-lists over block-lists; reject early with minimal detail
## Authentication & Authorization
- Authentication: verify identity; issue short-lived tokens/sessions
- Authorization: check permissions before actions; deny by default
- Centralize policies; avoid duplicating checks across code
Pattern:
```typescript
if (!user.hasPermission('resource:action')) throw ForbiddenError();
```
## Secrets & Configuration
- Never commit secrets; store in secret manager or env
- Rotate regularly; audit access; scope minimal
- Validate required env vars at startup; fail fast on missing
## Sensitive Data
- Minimize collection; mask/redact in logs; encrypt at rest and in transit
- Restrict access by role/need-to-know; track access to sensitive records
## Session/Token Security
- httpOnly + secure cookies where possible; TLS everywhere
- Short expiration; rotate on refresh; revoke on logout/compromise
- Bind tokens to audience/issuer; include minimal claims
## Logging (security-aware)
- Log auth attempts, permission denials, and sensitive operations
- Never log passwords, tokens, secrets, full PII; avoid full bodies
- Include requestId and context to correlate events
## Headers & Transport
- Enforce TLS; HSTS
- Set security headers (CSP, X-Frame-Options, X-Content-Type-Options)
- Prefer modern crypto; disable weak protocols/ciphers
## Vulnerability Posture
- Prefer secure libraries; keep dependencies updated
- Static/dynamic scans in CI; track and remediate
- Educate team on common classes; encode as patterns above

# Testing Standards
[Purpose: guide what to test, where tests live, and how to structure them]
## Philosophy
- Test behavior, not implementation
- Prefer fast, reliable tests; minimize brittle mocks
- Cover critical paths deeply; breadth over 100% pursuit
## Organization
Options:
- Co-located: `component.tsx` + `component.test.tsx`
- Separate: `/src/...` and `/tests/...`
Pick one as default; allow exceptions with rationale.
Naming:
- Files: `*.test.*` or `*.spec.*`
- Suites: what is under test; Cases: expected behavior
## Test Types
- Unit: single unit, mocked dependencies, very fast
- Integration: multiple units together, mock externals only
- E2E: full flows, minimal mocks, only for critical journeys
## Structure (AAA)
```typescript
it('does X when Y', () => {
// Arrange
const input = setup();
// Act
const result = act(input);
// Assert
expect(result).toEqual(expected);
});
```
## Mocking & Data
- Mock externals (API/DB); never mock the system under test
- Use factories/fixtures; reset state between tests
- Keep test data minimal and intention-revealing
## Coverage
- Target: [% overall]; higher for critical domains
- Enforce thresholds in CI; exceptions require review rationale
