+## Summary
+
+<!-- One or two sentences describing the change and why it is in scope for OCP. -->
+
+## Claude Code Alignment Evidence (REQUIRED)
+
+Per `ALIGNMENT.md`, every PR that touches `server.mjs` or any network-facing surface must fill out this section. PRs with this section blank or unchecked will receive a `request changes` review and cannot be merged.
+
+- [ ] **Corresponding `cli.js` reference.** I have identified the `cli.js` function and line range that performs the operation this PR forwards. Citation (format `cli.js:NNNN` or `cli.js vE4 <functionName>`):
+  <!-- e.g. cli.js:18423-18467 (function: sendUserMessage)  -->
+
+- [ ] **If `cli.js` does not perform this operation**, I have stated this explicitly below and justified the scope under `ALIGNMENT.md` Rule 2. (Note: in almost all cases this means the PR should be closed, not merged. Proxy layers do not invent endpoints.)
+  <!-- Justification, if applicable. Empty is fine when cli.js does perform the operation. -->
+
+- [ ] **Commit message citations.** Every "Claude Code uses X" or "cli.js uses X" assertion in every commit of this PR is immediately followed by a `cli.js:NNNN` or `cli.js vE4 <functionName>` citation. I have verified this by rereading each commit message.
+
+## Type of change
+
+- [ ] Bug fix (alignment with existing `cli.js` behavior)
+- [ ] Feature (new `cli.js` behavior now surfaced through OCP)
+- [ ] Refactor (no wire-level behavior change)
+- [ ] Deletion (unalignable feature removal per `ALIGNMENT.md` Unalignable Policy)
+- [ ] Documentation / governance
+
+## Reviewer checklist
+
+Reviewers: this section is for you, not the author. Do not approve until every box is checked.
+
+- [ ] I opened `cli.js` at the cited line range and confirmed the operation matches.
+- [ ] I ran (or confirmed CI ran) `.github/workflows/alignment.yml` and it passed.
+- [ ] I am not the commit author of any commit in this PR (Iron Rule 10).
+- [ ] If the PR asserts scope without a `cli.js` citation, I confirmed the justification is sound per `ALIGNMENT.md` Rule 2.

+# OCP Alignment Constitution
+
+**Status:** Active. This document is the supreme source of truth for OCP scope decisions. Conflicts with other documents (README, issues, prior commit messages) resolve in favor of this file.
+
+---
+
+## Core Principle
+
+OCP (Open Claude Proxy) is a **proxy layer** for the Claude Code CLI. It forwards, observes, and multiplexes the traffic that `cli.js` already emits. It is **not** an extension layer. If `cli.js` does not perform a given operation, or performs it differently, OCP does not invent one.
+
+---
+
+## Rules
+
+1. **Rule 1 (Grep First).** Before adding, renaming, or changing any endpoint, header, parameter, or response shape, the author must `grep` the reference `cli.js` and record the exact line numbers in the commit message and PR body. An absent grep hit is itself a finding and must be declared.
+
+2. **Rule 2 (No Invention).** OCP must not introduce endpoints, headers, request fields, or response fields that are not present in `cli.js`. Speculative "Claude Code probably uses X" statements are prohibited. If the behavior is not observable in `cli.js`, the feature is out of scope.
+
+3. **Rule 3 (Match the Implementation).** When `cli.js` does perform a given operation, OCP must match it byte-for-byte on the wire: same path, same method, same headers (including casing and ordering constraints), same body schema, same auth scheme. Deviations require an explicit, reviewed exception recorded in this file.
+
+4. **Rule 4 (Unalignable Features Are Deleted).** Any existing OCP feature that cannot be traced to a concrete `cli.js` reference is deleted. There is no "grandfathering" and no "keep it disabled." The policy is removal, not deprecation. See the Unalignable Policy section below.
+
+5. **Rule 5 (Cite Line Numbers in Commits).** Every commit that touches `server.mjs` must reference `cli.js` by line number or function name in the form `cli.js:NNNN` or `cli.js vE4 <functionName>`. Commits asserting "Claude Code uses X" without such a citation are blocked by CI and must be reverted on detection.
+
+---
+
+## Golden Reference: `cli.js`
+
+`cli.js` is the Claude Code CLI JavaScript bundle shipped inside the `@anthropic-ai/claude-code` npm package. It is the single source of truth for "what Claude Code actually does."
+
+### Canonical paths per machine

+- **Audit date:** `2026-04-20`

+
+## Historical Lesson: The 2026-04-11 Drift
+
+On 2026-04-11, commit `b87992f` ("fix: use dedicated /api/oauth/usage endpoint for reliable plan data") was merged. The commit message asserted that `/api/oauth/usage` was "the dedicated usage endpoint that Claude Code CLI uses."
+
+**This assertion was false.** The string `/api/oauth/usage` does not appear in `cli.js` at any version shipped up to that date. The endpoint was fabricated by an LLM-assisted authoring pass that generalized from adjacent OAuth paths without verifying against `cli.js`. A follow-up commit `cb6c2a8` ("fallback to stale cache on usage API 429 + extend cache to 15min") compounded the error by caching the fabricated response to hide the 4xx failures.
+
+**Impact:** The `/usage` progress bar in the dashboard was broken for nine days (2026-04-11 through 2026-04-20) before the drift was isolated.
+
+**Root cause:** LLM hallucination accepted without `grep cli.js` verification, compounded by the absence of a CI blacklist and the absence of this constitution.
+
+**Fix commit:** `fd7973a` (PR #21 — restored header-based `/usage`); follow-up `01e260c` (PR #24 — OAuth Bearer header correction)
+
+**Lesson codified:** Rules 1, 2, and 5 of this document; the CI blacklist in `.github/workflows/alignment.yml`; and the PR template evidence section exist to make the 2026-04-11 drift structurally impossible to repeat.
+
+---
+
+## Unalignable Policy
+
+A feature is **unalignable** if, after a good-faith search, it cannot be mapped to a specific `cli.js` line range or function.
+
+- Unalignable features are **deleted**, not disabled, not feature-flagged, not deprecated.
+- Deletion is the default outcome of an alignment audit finding. The burden of proof is on the feature, not on the auditor.
+- A deletion PR does not require user-facing deprecation notice, because the feature was never legitimately in scope.
+- If a user workflow depended on an unalignable feature, the correct remediation is to upstream the behavior into `cli.js` or to move it out of OCP into a separate tool. OCP does not retain it.
+
+---
+
+## Annual Alignment Audit
+
+- **Date:** 11 April each year (the anniversary of the `b87992f` drift).
+- **Scope:** Diff the current `cli.js` against the pinned SHA-256 in the Golden Reference section. For every network call in `server.mjs`, re-verify that the corresponding `cli.js` reference still exists at the cited line numbers (adjust citations if line numbers shifted across Claude Code versions).
+- **Output:** A signed audit note committed to `docs/alignment-audits/YYYY-04-11.md`, updating the pin.
+- **Failure mode:** Any audit finding that cannot be reconciled triggers an immediate deletion PR per the Unalignable Policy.
+
+---
+
+## Amendment Procedure
+
+This constitution is amended only by a PR that (a) cites the evidence motivating the amendment, (b) is reviewed by an independent reviewer per CC Iron Rule 10, and (c) updates the Historical Lesson section if the amendment was driven by an incident. Amendments never retroactively legitimize previously unalignable features.

+# OCP Project Session Instructions
+
+> **WARNING — READ BEFORE WRITING ANY CODE IN THIS REPO**
+>
+> Before touching `server.mjs` or any network-facing surface, read [`./ALIGNMENT.md`](./ALIGNMENT.md) in full. The constitution is binding. Non-compliant commits are reverted.
+
+---
+
+## Before starting any task
+
+1. Read `./ALIGNMENT.md`. Internalize the five Rules and the 2026-04-11 drift lesson.
+2. Run `/dev-start <task description>` to get a pre-flight plan that incorporates the iron rules, `SKILL_ROUTING.md`, this file, and `ALIGNMENT.md`.
+3. If the task touches `server.mjs`, locate the corresponding `cli.js` reference **before** drafting any code. No code is written ahead of the `grep cli.js` evidence.
+
+---
+
+## Hard requirements for `server.mjs` changes
+
+Every PR that modifies `server.mjs` must satisfy all three of the following. A PR missing any one of them is blocked from merge.
+
+1. **`cli.js` citation.** The commit message and PR body declare the corresponding `cli.js` function name and line number range, using the format `cli.js:NNNN` or `cli.js vE4 <functionName>`. If `cli.js` does not perform the operation, the PR must state this explicitly and justify scope under `ALIGNMENT.md` Rule 2 (in practice, this almost always means the PR should be closed).
+2. **CI blacklist pass.** The `alignment.yml` workflow must pass. The workflow greps `server.mjs` for known-hallucinated tokens (including `api/oauth/usage` and `api/usage`) and fails the build on any hit. Do not suppress the workflow. Do not add allowlist entries without an amendment PR to `ALIGNMENT.md`.
+3. **Independent reviewer (Iron Rule 10).** The implementation author may not self-approve. A separate reviewer — human or a subagent spawned with a fresh context — must read the diff, verify the `cli.js` citation by opening `cli.js` at the cited lines, and explicitly approve. A review comment that does not confirm the `cli.js` citation was checked is not a valid approval.
+
+---
+
+## Iron rules in force
+
+This repo operates under the CC Development Iron Rules (CC 开发铁律) v1.3. Three rules are load-bearing for OCP work:
+
+- **Iron Rule 10 (Code Review).** Every implementation phase has an independent reviewer. Self-review does not count. See `server.mjs` hard requirement #3 above.
+- **Iron Rule 11 (Incremental Diff Review).** Non-trivial work is split into the minimum reviewable unit — one PR per layer per severity. `ALIGNMENT.md`, `CLAUDE.md`, the PR template, and the CI workflow are therefore shipped as the same constitutional PR (they are one layer: governance), but any subsequent `server.mjs` remediation lands as its own PR.
+- **Iron Rule 12 (Pre-Brainstorm Prior-Art Search).** Before proposing any new endpoint or header, search GitHub, Anthropic docs, and the `cli.js` bundle. For OCP specifically, the `cli.js` grep is the decisive search: if it does not hit, Rule 2 of the constitution applies.
+
+The full iron rules are at `~/.claude/CC_DEV_IRON_RULES.md` (symlinked from the cc-rules repo on Tao's workstations). Load them into session context with `/cc-rules` when needed.
+
+---
+
+## Skills relevant to this repo
+
+- `/dev-start` — pre-flight planning, always first.
+- `/cc-rules` — load the iron rules into context.
+- `/agent-dispatch` — pick the correct model (opus for design and review, sonnet for straightforward edits, haiku for mechanical chores) before spawning any subagent.
+- `/cc-mem search <keyword>` — look up cross-machine memory for prior decisions, especially prior drift incidents.
+
+---
+
+## Commit message conventions
+
+- Subject line uses Conventional Commits (`fix:`, `feat:`, `docs:`, `refactor:`, `chore:`).
+- Any assertion of the form "Claude Code uses X" or "cli.js uses X" in the body must be immediately followed by a citation in the form `cli.js:NNNN` or `cli.js vE4 <functionName>`. CI performs a soft check for this pattern on all commits in the PR.
+- Co-author trailer is required for LLM-assisted commits (`Co-Authored-By: Claude <model> <noreply@anthropic.com>`).
+
+---
+
+## Project-level escalation
+
+If a design decision cannot be resolved by reference to `cli.js` and `ALIGNMENT.md`, escalate to Tao (老大) via `/cc-chat` rather than guessing. Silent guessing is what produced the 2026-04-11 drift.

+### Server Setup
+
+> **Recommended:** Install OCP on a device that stays powered on — Mac mini, NAS, Raspberry Pi, or a desktop that doesn't sleep. This ensures all clients always have access.
+
+**Prerequisites:**
+- Node.js 18+
+- [Claude CLI](https://docs.anthropic.com/en/docs/claude-cli) installed and authenticated (`claude auth login`)

 ```bash
+# 1. Clone and run setup
 git clone https://github.com/dtzp555-max/ocp.git
 cd ocp
 node setup.mjs
@@ -41,20 +64,243 @@ The setup script will:
 1. Verify Claude CLI is installed and authenticated
 2. Start the proxy on port 3456
 3. Install auto-start (launchd on macOS, systemd on Linux)
+4. Symlink `ocp` to `/usr/local/bin` for CLI access

-Then point your IDE to the proxy:
-
+**Single-machine use** — just set your IDE to use the proxy:
 ```bash
 export OPENAI_BASE_URL=http://127.0.0.1:3456/v1
 ```

-### Verify
+**LAN mode** — share with other devices on your network:
+```bash
+# Enable LAN access with per-user auth (recommended)
+node setup.mjs --bind 0.0.0.0 --auth-mode multi
+```

+Then create API keys for each person/device:
+```bash
+export OCP_ADMIN_KEY=your-secret-admin-key
+
+ocp keys add wife-laptop
+#  ✓ Key created for "wife-laptop"
+#    API Key: ocp_xDYzOB9ZKYzn...
+#    Copy this key now — you won't see it again.
+
+ocp keys add son-ipad
+ocp keys add pi-server
+```
+
+Run `ocp lan` to see your IP and ready-to-share instructions.

 ```bash
 curl http://127.0.0.1:3456/v1/models
 # Returns: claude-opus-4-6, claude-sonnet-4-6, claude-haiku-4
 ```

+---
+
+### Client Setup
+
+> Clients do **not** need to install Node.js, Claude CLI, or the OCP repo. Only `curl` and `python3` are required (pre-installed on most Linux/Mac systems).
+
+**One-command setup** — download the lightweight `ocp-connect` script:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/dtzp555-max/ocp/main/ocp-connect -o ocp-connect
+chmod +x ocp-connect
+./ocp-connect <server-ip>
+```
+
+**Zero-config** — when the server admin has set `PROXY_ANONYMOUS_KEY` (see [Anonymous Access](#anonymous-access-optional) below), just pass the server IP and nothing else. `ocp-connect` reads the anonymous key from `/health` and uses it automatically:
+
+```bash
+./ocp-connect <server-ip>
+```
+
+If the server requires a key, pass it with `--key`:
+```bash
+./ocp-connect <server-ip> --key <your-api-key>
+```
+
+Or as a one-liner (no file saved):
+```bash
+curl -fsSL https://raw.githubusercontent.com/dtzp555-max/ocp/main/ocp-connect | bash -s -- <server-ip>
+```
+

+- **Auto-discovers anonymous key** from `/health.anonymousKey` when no `--key` given (v1.3.0+, requires server v3.10.0+)
+- Configures OpenClaw automatically (including per-agent `auth-profiles.json` for multi-agent setups)
+- Detects Cline, Continue.dev, Cursor, and opencode, and prints setup hints (manual configuration required for these IDEs)
+
+On macOS, `launchctl setenv` vars reset on reboot — re-run `ocp-connect` after restart.

+
+**Web Dashboard:** Open `http://<server-ip>:3456/dashboard` in any browser for real-time monitoring — per-key usage, request history, plan utilization, and system health.
+
+![OCP Dashboard](docs/images/dashboard.png)
+
+### Auth Modes
+
+| Mode | Env | Use Case |
+|------|-----|----------|
+| `none` | `CLAUDE_AUTH_MODE=none` | Trusted home network, no auth needed |
+| `shared` | `CLAUDE_AUTH_MODE=shared` + `PROXY_API_KEY=xxx` | Everyone shares one key |
+| `multi` | `CLAUDE_AUTH_MODE=multi` + `OCP_ADMIN_KEY=xxx` | Per-person keys with usage tracking (recommended) |
+
+### Anonymous Access (optional)
+
+In `multi` mode, the admin can designate a single well-known "anonymous" key that bypasses `validateKey()` and grants public read/write access. This is useful for letting LAN users (or clients like OpenClaw multi-agent setups) connect without individual per-user keys.
+
+**Enable**:
+
+```bash
+export PROXY_ANONYMOUS_KEY=ocp_public_anon   # or any string of your choice
+ocp start                                    # or however you start the server
+```
+
+**Client side**: the anonymous key value is exposed via `GET /health` as the field `anonymousKey` (null when not set). Clients like `ocp-connect` can auto-discover and use it, so the end user doesn't need to get a personal key from the admin.
+
+**Security note**: setting this env var is an **opt-in** to public access — anyone who can reach your OCP endpoint can use it, up to any rate limits you configure. Don't enable this on internet-exposed OCP instances without additional protection.
+
+**Not a secret**: because `/health` is an unauthenticated endpoint, the anonymous key is **publicly readable** by anyone who can reach the server. That is intentional — the key exists so clients can self-configure without out-of-band coordination. Treat it as a convenience handle, not as an access credential.
+
+### Per-Key Quota (Budget Control)
+
+Prevent any single user from exhausting your subscription. Set daily, weekly, or monthly request limits per API key:
+
+```bash
+# Set a daily limit of 50 requests for a key
+curl -X PATCH http://127.0.0.1:3456/api/keys/wife-laptop/quota \
+  -H "Authorization: Bearer $OCP_ADMIN_KEY" \
+  -d '{"daily": 50}'
+
+# Set multiple limits at once
+curl -X PATCH http://127.0.0.1:3456/api/keys/son-ipad/quota \
+  -H "Authorization: Bearer $OCP_ADMIN_KEY" \
+  -d '{"daily": 20, "weekly": 100}'
+
+# Check current quota + usage
+curl http://127.0.0.1:3456/api/keys/wife-laptop/quota
+# → { "daily": { "limit": 50, "used": 12 }, "weekly": { "limit": null, "used": 34 }, ... }
+
+# Remove a limit (set to null)
+curl -X PATCH http://127.0.0.1:3456/api/keys/wife-laptop/quota \
+  -d '{"daily": null}'
+```
+
+When a key exceeds its quota, OCP returns HTTP 429 with a structured error:
+```json
+{
+  "error": {
+    "message": "Quota exceeded: 50/50 requests (daily). Resets 6h 12m.",
+    "type": "quota_exceeded",
+    "quota": { "period": "daily", "limit": 50, "used": 50, "resetsIn": "6h 12m" }
+  }
+}
+```
+
+- `null` = unlimited (default for all keys)
+- Only successful requests count toward quota
+- Admin and anonymous users are never subject to quotas
+- PATCH is a partial update — omitted fields are left unchanged
+
+### Important Notes
+
+- All users share your Claude Pro/Max **rate limits** (5h session + 7d weekly)
+- `ocp usage` shows how much quota remains
+- Keys are stored in `~/.ocp/ocp.db` (SQLite, zero external dependencies)
+- Admin key is required for key management API endpoints
+- The dashboard (`/dashboard`) and health check (`/health`) are always public

+## Response Cache
+
+OCP can cache responses to avoid redundant Claude CLI calls for identical prompts. This is useful during development when the same prompt is sent repeatedly.
+
+**Enable** by setting `CLAUDE_CACHE_TTL` (in milliseconds):
+
+```bash
+# Cache responses for 5 minutes
+export CLAUDE_CACHE_TTL=300000
+
+# Or update at runtime (no restart)
+ocp settings cacheTTL 300000
+```
+
+**How it works:**
+- Cache key = SHA-256 of `model` + `messages` + `temperature` + `max_tokens` + `top_p`
+- Cache hits return instantly — no Claude CLI process spawned
+- Works for both streaming and non-streaming requests
+- Multi-turn conversations (with `session_id`) are never cached
+- Expired entries are cleaned up automatically every 10 minutes
+
+**Management:**
+```bash
+# View cache stats
+curl http://127.0.0.1:3456/cache/stats
+# → { "entries": 42, "totalHits": 156, "sizeBytes": 284000 }
+
+# Clear all cached responses
+curl -X DELETE http://127.0.0.1:3456/cache
+
+# Disable cache at runtime
+ocp settings cacheTTL 0
+```
+
+Cache is **disabled by default** (`CLAUDE_CACHE_TTL=0`). All data is stored locally in `~/.ocp/ocp.db`.

 Restart: `openclaw gateway restart`

-## Troubleshooting
+### Telegram / Discord Usage

-### Requests fail with exit 143 / SIGTERM after ~60 seconds
+After installing the gateway plugin, use `/ocp` slash commands in your chat:

-**Symptom:** Claude returns errors or stops responding after about 60 seconds, especially during tool use (Bash, Read, etc.).
-
-**Cause:** OpenClaw's gateway has a default `idleTimeoutSeconds` of 60 seconds. When Claude calls tools, the token stream pauses while the tool executes — if that takes longer than 60s, the gateway kills the connection.
-
-**Fix:** `setup.mjs` (v3.2.1+) sets this automatically. If you installed an older version, add this to `~/.openclaw/openclaw.json`:
-
-```json
-{
-  "agents": {
-    "defaults": {
-      "llm": {
-        "idleTimeoutSeconds": 0
-      }
-    }

-Then restart: `openclaw gateway restart`

-### Agents stuck in "typing" but never respond
+## Troubleshooting

-Usually caused by stuck sessions from previous timeout errors. Fix:
+### Requests fail or agents stuck

 ```bash
-# Clear all sessions
+# Clear sessions and restart
 ocp clear
-
-# Restart both services
 ocp restart
+
+# If using OpenClaw gateway
 openclaw gateway restart
 ```

-If that doesn't help, manually clear the session store:
+### Usage shows "unknown"
+
+Usually caused by an expired Claude CLI session. Fix:
 ```bash
-# Find and reset stuck Telegram sessions
-cat ~/.openclaw/agents/main/sessions/sessions.json
-# Remove entries with "telegram" channel, then restart gateway
+claude auth login
+ocp restart
 ```

-## Upgrading from v3.0.x
-
-If you installed OCP before v3.1.0, the auto-start service used names that OpenClaw's gateway detected as conflicting (`ai.openclaw.proxy` on macOS, `openclaw-proxy` on Linux). Running `node setup.mjs` or `ocp update` will automatically migrate to the new neutral names.

-| `PROXY_API_KEY` | *(unset)* | Bearer token for API authentication |
+| `CLAUDE_NO_CONTEXT` | `false` | Suppress CLAUDE.md and auto-memory injection (pure API mode) |
+| `PROXY_API_KEY` | *(unset)* | Bearer token for shared-mode authentication |
+| `PROXY_ANONYMOUS_KEY` | *(unset)* | Well-known anonymous key allowlist (multi mode). When set, this exact string bypasses `validateKey()` and grants public access. Exposed via `/health.anonymousKey` so clients auto-discover. See [Anonymous Access](#anonymous-access-optional). |

 ## Security

- **Localhost only** — binds to `127.0.0.1`, not exposed to the network
- **Bearer token auth (optional)** — set `PROXY_API_KEY` to require auth
+- **Localhost by default** — binds to `127.0.0.1`; set `CLAUDE_BIND=0.0.0.0` to enable LAN access
+- **3-tier auth** — `none` (trusted network), `shared` (single key), `multi` (per-user keys with usage tracking)
+- **Timing-safe key comparison** — prevents timing attacks on API keys and admin keys
+- **Admin-only key management** — creating, listing, and revoking keys requires the admin key
+- **Public endpoints** — `/health` and `/dashboard` are always accessible without auth
 - **No API keys needed** — authentication goes through Claude CLI's OAuth session
+- **Keys stored locally** — `~/.ocp/ocp.db` (SQLite), never sent to external services
 - **Auto-start** — launchd (macOS) / systemd (Linux)

+
+Usage:
+  ocp-connect <host-ip> [options]
