Smoke regression checklist

This file is the backend manual regression baseline for svg-service.

Preconditions

• docker compose stack is up
• backend responds on port 9020
• valid admin API key is available
• test scheme exists

Environment

Use these variables in shell:

export API_URL="http://127.0.0.1:9020" export API_KEY="admin-local-dev-key" export SCHEME_ID="82086336d385427f9d56244f9e1dd772"

1. Health / system

• GET /healthz -> 200
• GET /api/v1/ping -> 200
• GET /api/v1/db/ping -> 200
• GET /api/v1/manifest -> 200

2. Scheme registry

• GET /api/v1/schemes -> 200
• GET /api/v1/schemes/{scheme_id} -> 200
• GET /api/v1/schemes/{scheme_id}/current -> 200
• GET /api/v1/schemes/{scheme_id}/versions -> 200

Validate:

• scheme_id is stable
• current version exists
• version list contains current version
• status and counts are consistent

3. Structure read model

• GET /api/v1/schemes/{scheme_id}/current/sectors -> 200
• GET /api/v1/schemes/{scheme_id}/current/groups -> 200
• GET /api/v1/schemes/{scheme_id}/current/seats -> 200

Validate:

• total counts are non-negative
• known sample scheme returns expected object lists
• seats contain seat_id / sector_id / group_id contract where applicable

4. SVG / display pipeline

• GET /api/v1/schemes/{scheme_id}/current/svg -> 200
• GET /api/v1/schemes/{scheme_id}/current/svg/display -> 200
• GET /api/v1/schemes/{scheme_id}/current/svg/display/meta -> 200
• GET /api/v1/schemes/{scheme_id}/current/svg/display?mode=optimized -> 200 or explicit controlled failure
• GET /api/v1/schemes/{scheme_id}/current/svg/display/meta?mode=optimized -> 200 or explicit controlled failure

Validate:

• response content type for svg endpoints is image/svg+xml
• meta returns scheme_id, scheme_version_id, view_box, width, height
• no 500 on passthrough mode
• unsupported mode returns 422

5. Pricing read / write contract

• GET /api/v1/schemes/{scheme_id}/pricing -> 200
• GET /api/v1/schemes/{scheme_id}/current/seats/{seat_id}/price -> 200 for priced seat
• GET /api/v1/schemes/{scheme_id}/test/seats/{seat_id} -> 200 for known seat
• POST /api/v1/schemes/{scheme_id}/pricing/categories?expected_scheme_version_id={draft_version_id} -> 200 for valid draft
• POST /api/v1/schemes/{scheme_id}/pricing/categories?expected_scheme_version_id=deadbeef... -> 409 for stale draft

Validate:

• pricing bundle contains categories and rules arrays
• effective seat price resolves according to domain priority
• test seat preview explains selectable / has_price state
• pricing write responses are stable and typed
• stale pricing mutation returns detail.code = stale_draft_version

6. Draft publish preview

• GET /api/v1/schemes/{scheme_id}/publish/validation -> 200
• POST /api/v1/schemes/{scheme_id}/draft/pricing/snapshot -> 200 when scheme is in draft
• GET /api/v1/schemes/{scheme_id}/draft/publish-preview?refresh=true -> 200
• GET /api/v1/schemes/{scheme_id}/draft/publish-preview -> 200
• GET /api/v1/schemes/{scheme_id}/draft/publish-preview?refresh=true&baseline_scheme_version_id={published_version_id} -> 200

Validate:

• refresh and cached read both succeed
• preview summary contains is_publishable / has_structure_changes / has_artifacts / snapshot_available
• pricing_coverage is internally consistent
• baseline override returns override strategy when explicit baseline is provided
• preview retention does not grow unbounded for same version+variant

7. Admin / ops

• GET /api/v1/admin/schemes/{scheme_id}/current/artifacts -> 200
• GET /api/v1/admin/schemes/{scheme_id}/current/validation -> 200
• GET /api/v1/admin/artifacts/publish-preview/audit -> 200
• POST /api/v1/admin/artifacts/publish-preview/cleanup?dry_run=true -> 200

Optional:

• POST /api/v1/admin/schemes/{scheme_id}/current/display/regenerate?mode=passthrough -> 200
• POST /api/v1/admin/display/backfill?mode=passthrough&limit=10&only_missing=true -> 200

Validate:

• audit endpoint does not report orphan files or missing files for DB rows in normal state
• validation report is readable and deterministic
• admin routes do not produce 500 for healthy scheme state

8. Audit trail

• GET /api/v1/schemes/{scheme_id}/audit -> 200

Validate:

• recent publish preview / pricing / version events are present when corresponding operations were run
• audit total is non-negative
• event payloads stay JSON-serializable

9. Fail criteria

Regression is considered failed if any of the following happen:

• health or db ping fails
• any stable read endpoint returns 500
• passthrough display endpoint fails on known-good sample
• publish preview refresh or cached read returns 500
• pricing bundle contract changes unexpectedly
• pricing write contract regresses or stops returning typed payloads
• stale draft guard stops returning 409 on pricing mutations
• admin audit/cleanup endpoints fail on healthy environment
• artifact retention grows without bound for repeated preview refresh on same variant

10. Operator note

Run this checklist after:

• schema changes
• pricing schema/repository refactors
• artifact lifecycle changes
• display pipeline changes
• route reorganization
• startup/import/config changes
