senke 0e7097ed1b chore(cleanup): J1 — purge 220MB debris, archive session docs (complete)
First-attempt commit 3a5c6e184 only captured the .gitignore change; the
pre-commit hook silently dropped the 343 staged moves/deletes during
lint-staged's "no matching task" path. This commit re-applies the intended
J1 content on top of bec75f143 (which was pushed in parallel).

Uses --no-verify because:
- J1 only touches .md/.json/.log/.png/binaries — zero code that would
  benefit from lint-staged, typecheck, or vitest
- The hook demonstrated it corrupts pure-rename commits in this repo
- Explicitly authorized by user for this one commit

Changes (343 total: 169 deletions + 174 renames):

Binaries purged (~167 MB):
- veza-backend-api/{server,modern-server,encrypt_oauth_tokens,seed,seed-v2}

Generated reports purged:
- 9 apps/web/lint_report*.json (~32 MB)
- 8 apps/web/tsc_*.{log,txt} + ts_*.log (TS error snapshots)
- 3 apps/web/storybook_*.json (1375+ stored errors)
- apps/web/{build_errors*,build_output,final_errors}.txt
- 70 veza-backend-api/coverage*.out + coverage_groups/ (~4 MB)
- 3 veza-backend-api/internal/handlers/*.bak

Root cleanup:
- 54 audit-*.png (visual regression baselines, ~11 MB)
- 9 stale MVP-era scripts (Jan 27, hardcoded v0.101):
  start_{iteration,mvp,recovery}.sh,
  test_{mvp_endpoints,protected_endpoints,user_journey}.sh,
  validate_v0101.sh, verify_logs_setup.sh, gen_hash.py

Session docs archived (not deleted — preserved under docs/archive/):
- 78 apps/web/*.md     → docs/archive/frontend-sessions-2026/
- 43 veza-backend-api/*.md → docs/archive/backend-sessions-2026/
- 53 docs/{RETROSPECTIVE_V,SMOKE_TEST_V,PLAN_V0_,V0_*_RELEASE_SCOPE,
          AUDIT_,PLAN_ACTION_AUDIT,REMEDIATION_PROGRESS}*.md
                        → docs/archive/v0-history/

README.md and CONTRIBUTING.md preserved in apps/web/ and veza-backend-api/.

Note: The .gitignore rules preventing recurrence were already pushed in
3a5c6e184 and remain in place — this commit does not modify .gitignore.

Veza API Contract (Finalized)

1. Overview

This document defines the finalized API contract for the Veza backend. All endpoints adhere to strict JSON standards, snake_case naming conventions, and a unified response envelope.

2. Global Standards

  • Protocol: HTTP/1.1
  • Content-Type: application/json
  • Charset: utf-8
  • Date Format: ISO 8601 (YYYY-MM-DDThh:mm:ssZ)
  • Naming Convention: snake_case for all JSON keys.

3. Response Envelope

Every API response (Success or Error) is wrapped in a unified envelope.

3.1. Success Response

HTTP Status: 200 OK, 201 Created

{
  "success": true,
  "data": {
    // Resource or Object
    "id": "123",
    "name": "example"
  },
  "error": null
}

3.2. Error Response

HTTP Status: 4xx, 5xx

{
  "success": false,
  "data": null,
  "error": {
    "code": 400,
    "message": "Validation failed",
    "details": [
      {
        "field": "email",
        "message": "Invalid email format"
      }
    ],
    "request_id": "req_123xyz"
  }
}

4. Error Handling

Frontend clients should check the success boolean.

  • If success is false, read the error object.
  • error.code maps to standard HTTP status codes but provides application-level context.
  • error.details is an optional array of field-specific errors (useful for form validation).

5. Authentication

  • Header: Authorization: Bearer <token>
  • Token Type: JWT (Access Token)
  • Refresh: Use /api/v1/auth/refresh to rotate tokens.

6. Pagination

Endpoints returning lists support cursor-based or offset-based pagination. Helper structure in data:

{
  "list": [...],
  "pagination": {
    "page": 1,
    "limit": 20,
    "total": 100,
    "has_next": true
  }
}

7. Versioning

  • Current Version: v1
  • Base Path: /api/v1

8. Key Changes (Remediation Phase)

  • Unified Handlers: All handlers now use RespondSuccess and RespondWithAppError.
  • Snake Case: All DTOs enforce snake_case.
  • Validation: Strict validation on all request bodies using go-playground/validator.
