+# ZERO-ONE Version Management Agent Skill SSOT
+
+Use this skill when working on production release records, release intent labels/body, `main` production deployment workflow, rollback metadata, or `releases/prod-*.yaml` in `study-platform-client`.
+
+This file is the shared skill source of truth. Codex and Claude wrappers must stay thin and point here instead of duplicating the workflow.
+
+## Required reading order
+
+1. `ops/release-record-shared-contract.md` - FE/BE shared payload and final record contract.
+2. `ops/version-management.md` - frontend repository rule and release-record policy.
+3. `ops/release-intent.md` - human usage for PR labels/body and bootstrap.
+4. `ops/deploy-checklist.md` or `ops/rollback.md` only when deploying or rolling back.
+5. Relevant scripts/workflows only after the docs above:
+   - `.github/workflows/deploy-prod.yml`
+   - `.github/workflows/release-record-check.yml`
+   - `scripts/release/resolve-prod-release-intent.mjs`
+   - `scripts/release/generate-prod-release-record.mjs`
+   - `scripts/release/generate-backend-prod-release-record.mjs`
+   - `scripts/release/validate-release-record.mjs`
+   - `ops/backend-release-dispatch.md`
+   - `ops/release-record-shared-contract.md`
+
+## Non-negotiable rules
+
+- This skill applies to `main` production releases only. Do not change `develop` deployment behavior unless the user explicitly asks.
+- `ops/release-record-shared-contract.md` is the shared FE/BE contract; `releases/` is the frontend repository source of truth for successful production FE/BE/DB/rollback combinations.
+- Frontend repo owns only the frontend version-management rule. Do not add the backend repository rule here.
+- Production version metadata comes from PR intent or backend dispatch payload, not per-release repository variables.
+- Exactly one release intent is allowed: `release:major`, `release:minor`, or `release:patch`. Use `N/A` for no DB migration version.
+- If multiple `release:*` labels are present, or label intent conflicts with body `release`, fail instead of guessing.
+- First recorded frontend production release requires explicit bootstrap approval metadata in the PR body: `bootstrap: approved`, `base_version` or `version`, backend image/commit/version, and rollback frontend/backend fixed image tags.
+- `prod` and `latest-prod` are pointer tags only. They are never valid rollback targets and must fail if used as inherited or supplied backend/rollback images.
+- Image dates belong in `release_id`, not image tags.
+
+## Implementation workflow for agents
+
+1. Inspect current branch and changed files.
+2. Read the docs in the required reading order.
+3. For workflow/script changes, add deterministic checks for:
+   - first-release bootstrap without accidental defaulting,
+   - duplicate release label failure,
+   - pointer-tag rejection,
+   - docs/examples matching supported script keys,
+   - backend dispatch schema validation,
+   - duplicate `metadata.backend_deploy_id` rejection.
+4. Validate with targeted commands first:
+   - `node --check scripts/release/resolve-prod-release-intent.mjs`
+   - local resolver smoke cases for bootstrap, duplicate labels, pointer tags, and normal latest-release inheritance.
+   - `node scripts/release/validate-release-record.mjs releases`
+5. Then run repository checks required by the project for the changed scope.
+
+## Human handoff format
+
+Report:
+
+- changed files,
+- what happens on `main` merge,
+- what the PR author must put in labels/body,
+- verification commands and results,
+- any remaining manual setup such as optional `PROD_E2E_BASE_URL`.

+# Backend Production Release Dispatch Contract
+
+This is the frontend repository contract for backend production deployments. Backend automation is the producer of backend deploy facts. The frontend repository is the final release-record writer.
+
+This document follows the shared FE/BE contract in `ops/release-record-shared-contract.md`.
+
+## Trigger
+
+Backend production deploy success must call the frontend repository with `repository_dispatch` or an equivalent API trigger.
+
+```json

+  "event_type": "backend-prod-deployed",

+```
+
+## Required `client_payload`
+
+```json
+{
+  "release_id": "prod-20260517-2100",
+  "env": "prod",

+  }
+}
+```
+
+## Required fields
+
+- `release_id` - `prod-YYYYMMDD-HHmm`
+- `env` - must be `prod`
+- `backend.image` - fixed immutable backend image tag
+- `backend.commit` - backend short commit
+- `backend.version` - `vMAJOR.MINOR.PATCH`
+- `backend.changed` - must be `true`
+- `database.changed` - boolean
+- `database.migration_version` - migration version or `N/A`
+- `database.migration_files` - array
+- `rollback.backend` - fixed immutable backend rollback image tag
+- `metadata.release_intent` - `patch`, `minor`, or `major`
+- `metadata.bootstrap_mode` - boolean
+- `metadata.backend_deploy_id` - unique backend deployment id
+
+## Optional fields
+
+- `summary`
+- `metadata.previous_deploy_image`
+- `metadata.pull_request_number`
+- `metadata.pull_request_labels`
+
+## Frontend behavior
+
+When the dispatch arrives, the frontend repository workflow:
+
+1. validates the payload strictly,
+2. reads the latest `releases/prod-*.yaml` to identify current frontend production state,
+3. creates a new release record with `frontend.changed=false` and `backend.changed=true`,
+4. writes `metadata.backend_deploy_id`,
+5. fails if the same `backend_deploy_id` is already recorded,
+6. fails if image tags use `prod`, `latest-prod`, dates, or non-canonical versions.
+
+The workflow does not deploy frontend code. It only records the new atomic production combination `FE(current) + BE(new)`.
+
+## Failure principle
+
+Do not guess. If the payload is missing, invalid, duplicated, or the frontend repository has no previous release record to identify current frontend production state, the workflow must fail instead of writing a wrong release record.
