docs(release): v3.15.0 — README AI prompt blocks + Upgrading rewrite + CHANGELOG

§Installation, §Upgrading, §Troubleshooting each start with a copy-paste
AI prompt block for Claude Code / Cursor / Copilot. The Upgrading section
explains the three paths (light / full / fresh-install) and rollback usage.

All Commands table gains an `ocp doctor` row.

package.json bumped to 3.15.0.

CHANGELOG.md gains the v3.15.0 entry covering doctor, the cross-version
update path, --rollback, fresh-install routing, and AI prompt blocks.
Notes the dependency on PR #90 (plist env merge bug fix, already merged).

No cli.js citation needed: docs + version bump only, no server.mjs change.

 # Changelog
 
+## v3.15.0 — 2026-XX-XX (release date filled at tag time)
+
+### Features
+
+- **`ocp doctor`** — health & upgrade-readiness check; primary entry for AI-driven debugging.
+  `--json` mode emits a `next_action` with `ai_executable[]` for agents to run verbatim
+  and `human_required[]` for steps requiring the user (typically only OAuth).
+- **`ocp update` cross-version path** — for cross-minor jumps (e.g. v3.10 → v3.14),
+  `ocp update` now runs doctor → snapshot → `setup.mjs` (with the plist env-merge from
+  PR #90) → service restart → post-flight `/health` + `/v1/models` verification.
+  Same-patch updates retain the existing light path; users see no change for routine
+  patch bumps.
+- **`ocp update --rollback`** — restore the most recent (or specified) upgrade snapshot.
+  Snapshots are saved to `~/.ocp/upgrade-snapshot-<ISO-ts>/` and never auto-deleted.
+- **Fresh-install routing** — `ocp update` on installations < v3.4.0 routes to a fresh-install
+  flow (with `--yes` to skip confirmation; AI agents pass this). OAuth survives via Claude
+  Code's credential store; users do not re-OAuth unless their token was independently broken.
+- **AI prompt blocks in README** — §Installation, §Upgrading, and §Troubleshooting each
+  start with a copy-paste prompt for Claude Code / Cursor / Copilot, so users can drive
+  install / setup / upgrade through their existing AI assistant.
+
+### Behavior changes
+
+- `ocp update` may take 10–30s longer when a cross-minor jump triggers the full path
+  (snapshot + post-flight). Patch bumps are unchanged.
+- Pre-v3.4.0 installs are routed to fresh-install rather than failing silently or
+  half-migrating.
+
+### Governance
+
+- No `cli.js` citation needed (no `server.mjs` change). ALIGNMENT.md Rule 2 not engaged.
+- Depends on PR #90 (plist env merge bug fix; merged before this release).
+

+## Upgrading
+
+The simplest path: ask your AI.
+
+  Paste this prompt:
+
+  ```
+  Upgrade my OCP. Run `ocp update` and follow whatever it says.
+  If it tells me to run `claude auth login`, I'll do that.
+  ```
+
+What `ocp update` does:
+
+- **Patch bump** (e.g. `v3.14.0 → v3.14.1`):
+  light path (git pull + npm install + restart).
+- **Cross-minor** (e.g. `v3.10 → v3.14`):
+  full path: pre-flight check, snapshot, `setup.mjs` (with plist env-merge),
+  service restart, post-flight `/health` and `/v1/models` verification.
+- **Old version** (< v3.4.0):
+  fresh-install. Pre-v3.4 lacked admin-key/usage-db, so there is nothing to
+  migrate. Your OAuth token (managed by the Claude Code CLI, not OCP) is
+  preserved; you do not need to re-OAuth unless your token expired
+  separately.
+
+Snapshots are saved to `~/.ocp/upgrade-snapshot-<ISO-ts>/` and never
+auto-deleted. Clean old ones with `rm -rf ~/.ocp/upgrade-snapshot-*` once
+you're confident the upgrade is stable.
+
+### Manual upgrade — same command, no AI
 
 ```bash
-# Check if a new version is available
+ocp update                  # smart-pick path
-ocp update --check
+ocp update --check          # show available updates, don't apply
-
+ocp update --dry-run        # preview plan
-# Pull latest, sync plugin, restart proxy — one command
+ocp update --target v3.13.0 # pin a specific version
-ocp update
+ocp update --rollback       # restore most recent snapshot
+ocp update --rollback --list
+ocp update --rollback --dry-run
 ```
 
-`ocp update` runs (in order): `git pull` → `npm install` → plugin sync → **OpenClaw model registry sync** (v3.11.0+) → proxy restart → health check.
+### When upgrade fails
+
+`ocp update` prints a recovery line on failure. To restore from the snapshot:
+
+```bash
+ocp update --rollback
+ocp doctor
+```
+
+If `ocp doctor` still reports problems after rollback, open a GitHub issue
+with the snapshot path and the doctor JSON output (`ocp doctor --json`).

 ### Setup fails with "claude: command not found"
 
 `setup.mjs` requires the Claude CLI to be on `PATH`. Install it via the [official guide](https://docs.anthropic.com/en/docs/claude-cli), confirm with `which claude`, then run `claude auth login` before re-running `node setup.mjs`.
