OLP — Open LLM Proxy

A personal- and family-scale multi-provider LLM proxy. One HTTP endpoint, many subscriptions behind it, automatic routing, automatic fallback, content-addressed caching — so your IDEs and family clients keep working as long as any of your subscriptions has quota left.

Status: v0.3.0 shipped (2026-05-25) — Phase 1 multi-provider proxy core (v0.1.0 + v0.1.1) + Phase 2 multi-key auth + audit + owner gating + keygen CLI (v0.2.0) + Phase 3 Dashboard + audit query layer + daily audit rotation (v0.3.0). Phase 4 (per-key per-provider auth + audit retention + SQLite hybrid + provider-cost weights) is the next planned milestone. Sections marked placeholder land alongside the relevant phase of work (see phase plan).

Why OLP

On 2026-05-14, Anthropic announced (effective 2026-06-15) that claude -p, the Agent SDK, and third-party agent traffic move out of the Pro/Max subscription pool into a separate fixed monthly Agent SDK Credit pool. OCP, OLP's predecessor, was a proxy around a single CLI — its core assumption was "subscription = unlimited within rate limits". That assumption breaks for Anthropic on the effective date.

The structural response is to stop relying on one provider's subscription terms remaining favourable. OLP spreads risk across multiple providers whose subscriptions still include CLI/programmatic use, routes intelligently between them, and caches aggressively so every request that does spawn a CLI counts.

OLP is not: a commercial multi-tenant SaaS; an enterprise gateway competing with LiteLLM / OpenCode / CLIProxyAPI on breadth; a model-capability router ("route to the smartest model" — you pick the model); a conversation-state store (your client handles that).

See ALIGNMENT.md for OLP's constitution and docs/adr/ for the founding ADRs.

Quick Start

placeholder — lands with Phase 1.

Anticipated shape:

# install
npm install -g @dtzp555-max/olp

# run setup (writes ~/.olp/config.json, asks which providers to enable)
olp setup

# start the proxy (default port 4567 since v0.4.0 — moved off OCP's 3456 so
# OLP and OCP can co-host on the same machine. Set OLP_PORT=3456 if you have
# no OCP on the machine and want the old default.)
olp start

# point your IDE at http://localhost:4567/v1/chat/completions with the OLP API key from `olp keys list`.

Supported Providers

Source of truth: models-registry.json. This table is regenerated from the registry per the release_kit overlay; do not edit it out of sync.

OLP distinguishes Candidate Providers (declared as intended, not yet pinned) from Enabled Providers (authority pin filled + plugin landed + Phase audit passed). The v0.1 founding commit ships zero Enabled Providers — enablement is a Phase audit deliverable, not a bootstrap claim. See ALIGNMENT.md § Provider Inventory for the transition gate.

Candidate Providers

Provider key	CLI	Subscription / auth	Anticipated Tier	Anticipated Phase
anthropic	claude -p	Pro / Max OAuth (pre-2026-06-15); Agent SDK Credit pool after	D (re-eval post-2026-06-15)	Phase 1
openai	codex exec --json	ChatGPT Pro OAuth or API key	D	Phase 2
mistral	vibe --prompt --output json	Le Chat Pro API key	D	Phase 3
grok	grok -p --output-format streaming-json	xAI Build xai-... API key	C	Phase 8+
kimi	kimi -p --output-format stream-json	Moonshot Kimi API key	C	Phase 8+
minimax	TBD	MiniMax Token Plan (¥29+/mo)	B	Phase 8+
glm	TBD	Zhipu Coding Plan ($10+/mo)	B	Phase 8+
qwen	TBD	Alibaba Coding Plan ($50/mo)	B	Phase 8+

Risk tier guide. D = permissive / safe (eligible for default-enabled); C = tightening signal, no enforcement history (opt-in); B = service-level key revocation risk (opt-in + consent); A = excluded by default (cannot be opt-in enabled). Tier B providers prompt for explicit consent on first enable and record consent in ~/.olp/config.json. See ALIGNMENT.md § Risk Tier Framework.

Excluded by default (Tier A — evidence-backed, pending primary-source pin). Google Antigravity. See ADR 0006 for the named-prohibition + no-cost-advantage + reinstatement-friction rationale, and for the primary-source pinning follow-up that may force a Tier reconsideration if the Google FAQ language cannot be sourced within 90 days of 2026-05-23.

Configuration

placeholder — full configuration reference lands with Phase 4 (fallback engine).

OLP reads its config from ~/.olp/config.json. The minimum useful shape:

{
  "routing": {
    "chains": {
      "<requested-model>": [
        { "provider": "<key>", "model": "<provider-model-id>" },
        { "provider": "<key>", "model": "<provider-model-id>" }
      ]
    },
    "soft_triggers": {
      "<provider-key>": { "<trigger>": <threshold> }
    }
  }
}

Note: routing.soft_triggers thresholds are parsed and stored but have no runtime effect at v0.1 — the quota polling path (quotaStatus() per hop) is deferred to v1.x per ADR 0004 Amendment 2. The evaluation logic exists and is tested; only the production data ingestion path is deferred.

Trigger types, fallback safety, idempotency rules, and the full example config land here when Phase 4 ships. See ADR 0004 (Fallback Engine Semantics & Safety) for the design.

API Endpoints

Endpoint	Method	Phase	Status	Description
/v1/chat/completions	POST	1	✅ Shipped	OpenAI-compatible Chat Completions entry. Internally normalized to IR, dispatched to a provider plugin, response shape converted back.
/v1/models	GET	1	✅ Shipped	Lists models from models-registry.json.
/health	GET	1	✅ Shipped	Per-provider health snapshot. Phase 2 owner-only-trim: full per-provider details to owner identity; trimmed { ok, version } to guest / anonymous. Gate via auth.owner_only_endpoints config. Optional anonymousKey field (D69 / Phase 4, v0.4.0) appears in both trimmed and full payloads when auth.advertise_anonymous_key: true AND auth.allow_anonymous: true AND at least one non-revoked guest-tier key has plaintext_advertise: true (see ADR 0011 for the trusted-LAN-only invariant). Default off — field absent when prereqs unmet.
/dashboard	GET	3	✅ Shipped (D50 + D51)	Owner-only multi-provider dashboard HTML (4 panels: quota / 24h request stats / 30d spend trend / top fallback chains; 30s poll with visibilitychange pause). Owner-only_block; non-owner identities receive 401. Localhost-bound by default.
/v0/management/dashboard-data	GET	3	✅ Shipped (D50)	JSON aggregate consumed by the dashboard 30s poll: { generated_at, window_24h, cache_hit_24h, quota, spend_trend_30d, top_fallback_chains_24h, cache_stats }. Owner-only_block.
/v0/management/quota	GET	3	✅ Shipped (D50)	Per-provider quota snapshot via provider.quotaStatus() (subset of dashboard-data; useful for scripted monitoring). Owner-only_block.
/cache/stats	GET	3	✅ Shipped (D50)	Live in-memory cacheStore.stats() ({ hits, misses, size, inflightCount } + generated_at). Owner-only_block.

Environment Variables

placeholder — full table lands per-phase as variables are introduced.

Variable	Default	Description
OLP_PORT	4567	HTTP listener port. Moved off 3456 at D60 / v0.4.0 to co-host with OCP — set OLP_PORT=3456 to restore the pre-D60 default.
OLP_CLAUDE_BIN	claude (from PATH)	Override path to the claude binary (Anthropic provider). Useful when multiple claude installs are present.
OLP_CODEX_BIN	codex (from PATH)	Override path to the codex binary (OpenAI provider).
OLP_VIBE_BIN	vibe (from PATH)	Override path to the vibe binary (Mistral provider).

config.json keys introduced at Phase 4

These live in ~/.olp/config.json (not env vars) — they're documented here alongside the env-var table for discoverability.

Config key	Default	Description
streaming.heartbeat_interval_ms	0 (disabled)	D61 / Phase 4. SSE keepalive comment frames during stream-silent windows. Set >0 (e.g. 15000 for 15s) when OLP runs behind nginx / Cloudflare / Tailscale Funnel with idle-abort timeouts.
auth.advertise_anonymous_key	false	D69 / Phase 4. When true, surfaces an existing guest-tier key's plaintext via /health.anonymousKey so olp-connect <ip> can self-bootstrap clients on the LAN with zero out-of-band coordination. Requires auth.allow_anonymous: true AND at least one key created via olp-keys keygen --anonymous --advertise. Trusted-LAN-only — see ADR 0011.

Operator CLI surfaces (Phase 4)

• olp (Node CLI at bin/olp.mjs): status / health / usage / models / cache / providers / chain show / logs / restart / keys / doctor. Run npx olp --help for full subcommand reference. olp doctor --json emits a machine-readable next_action.ai_executable[] payload designed for AI agents to self-repair OLP. See ADR 0010 § Phase 4 D-day plan and ADR 0002 Amendment 7 (per-plugin doctorChecks() contract).
• olp-connect (bash at bin/olp-connect): zero-config LAN client setup — detects Cline / Continue.dev / Cursor / Aider / Claude Code / OpenClaw and configures each. Run bash bin/olp-connect --help. Requires python3 for JSON parsing.
• olp-keys keygen --anonymous --advertise: creates a guest-tier key with the plaintext stored alongside its hash so /health.anonymousKey can publish it. Prints an explicit ADR-0011 warning at keygen time.

Per-provider auth env vars

These variables configure credential discovery for each provider plugin. Setting the correct one for your provider is usually required for OLP to make successful requests.

Anthropic (claude -p)

Variable	Default behavior	Description
CLAUDE_CODE_OAUTH_TOKEN	Searches ~/.claude/.credentials.json first, then macOS keychain (darwin only)	Directly supplies the OAuth access token. Highest-precedence override; bypasses all credential-discovery logic. Useful in CI/headless environments where the keychain is unavailable.

OpenAI Codex (codex exec --json)

Variable	Default behavior	Description
OPENAI_CODEX_AUTH_PATH	~/.codex/auth.json (or $CODEX_HOME/auth.json)	Overrides the full path to the Codex auth artifact. When set, no other path is tried; missing or malformed file returns null (no auth). Useful for CI test fixtures.
CODEX_HOME	~/.codex	Overrides the Codex home directory. $CODEX_HOME/auth.json becomes the default auth path. Ignored when OPENAI_CODEX_AUTH_PATH is set explicitly.

Mistral Vibe (vibe --prompt)

Variable	Default behavior	Description
MISTRAL_API_KEY	Reads $VIBE_HOME/.env (default ~/.vibe/.env)	Directly supplies the Mistral API key. Highest-precedence override per DOCS-2; bypasses .env file lookup.
MISTRAL_VIBE_AUTH_PATH	~/.vibe/.env (or $VIBE_HOME/.env)	Overrides the full path to the Vibe .env auth file. Evaluated only when MISTRAL_API_KEY is not set. When set, no other path is tried; missing or malformed file returns null (no auth).
VIBE_HOME	~/.vibe	Overrides the Vibe home directory. $VIBE_HOME/.env becomes the default auth path. Ignored when MISTRAL_API_KEY or MISTRAL_VIBE_AUTH_PATH is set explicitly.

📋 Planned (Phase 2) — not yet read by the codebase:

• OLP_HOME (~/.olp) — Config, providers, keys, cache, logs root. Currently hardcoded to ~/.olp/config.json in loadFallbackConfigSync; the env override path is a Phase 2 config-layer deliverable.
• OLP_LOG_LEVEL (info) — Log level filter (error/warn/info/debug). logEvent currently writes unconditionally; level filtering is a Phase 2 observability deliverable.

See also the Implementation status table.

---

Response Headers

Every response served through OLP carries:

• X-OLP-Provider-Used: <provider-key> — which provider's plugin served the request. On a chain-exhausted response, this identifies the chain's configured primary entry (chain[0]), not necessarily the first hop where spawn() was invoked — see ADR 0004 Amendment 6 for the v0.1 chain-origin semantics and the v1.x soft-trigger reactivation note.
• X-OLP-Model-Used: <model-id> — which model the served provider used.
• X-OLP-Fallback-Hops: <n> — number of fallback hops (0 if served by the primary chain entry).
• X-OLP-Cache: hit | miss | bypass — cache layer outcome.
• X-OLP-Latency-Ms: <ms> — end-to-end latency observed at the proxy.

If a fallback chain is exhausted, X-OLP-Fallback-Exhausted lists the tried providers in order.

---

Implementation status (as of 2026-05-25, post-v0.2.0)

Phase 1 closed at v0.1.1 (multi-provider proxy core + pre-Phase-2 cleanup). Phase 2 closed at v0.2.0 (multi-key auth + audit + owner gating + keygen CLI; ADR 0007 § 10 all 11 acceptance criteria shipped). Phase 3 closed at v0.3.0 (Dashboard + lib/audit-query.mjs + daily audit rotation; ADR 0008 § 10 all 15 acceptance criteria shipped). Phase 4 (per-key per-provider auth + audit retention + SQLite hybrid + provider-cost weights) is the next planned milestone. This table reflects what is currently shipped vs. what is designed for later phases.

models-registry.json	✅ Shipped	SPOT for (provider, model) metadata
test-features.mjs	✅ Shipped	Comprehensive test suite covering IR, cache, fallback, and integration paths (CI: test.yml)
lib/keys.mjs	✅ Phase 2 shipped (D44 + D45 + D46)	Multi-key auth core (createKey / validateKey / listKeys / revokeKey / touchLastUsed) per ADR 0007 §§ 5/6.1/6.3/6.3.5/6.4/9.4 + loadAuthConfigSync for auth.allow_anonymous / owner_only_endpoints / fallback_detail_header_policy. Server wires validateKey per request, filters chain by providers_enabled, fires touchLastUsed post-response, trims /health payload for non-owner, gates X-OLP-Fallback-Detail emission by policy.
bin/olp-keys.mjs	✅ Phase 2 shipped (D47)	Keygen CLI per ADR 0007 § 9.1. npx olp-keys keygen --owner generates an owner key + prints plaintext token once; npx olp-keys list enumerates keys (token_hash redacted); npx olp-keys revoke --id=X marks a key revoked. --olp-home=<path> overrides ~/.olp/.
lib/audit.mjs	✅ Phase 2 + 3 (D45 append + D52 rotation)	Append-only ndjson audit at ~/.olp/logs/audit.ndjson per ADR 0007 § 6.2 + § 8. appendAuditEvent fires for every /v1/* + /v0/management/* request (success, 401, 403, 5xx). Warn + 1 retry on append failure; no memory buffer at Phase 2 (forward path). PII excluded. D52 adds synchronous daily rotation per ADR 0008 § 5 — first append after UTC midnight renames live → audit-YYYY-MM-DD.ndjson.
lib/audit-query.mjs	✅ Phase 3 shipped (D49)	Audit ndjson aggregate query layer per ADR 0008 § 4. 5 functions: discoverAuditFiles, readAuditWindow, aggregateRequests, topFallbackChains, spendTrendDaily, cacheHitRateWindow. In-memory cross-file scan; PII guard at output. Consumed by /v0/management/dashboard-data.
dashboard.html	✅ Phase 3 shipped (D50 stub + D51 full UI)	Owner-only multi-provider dashboard per ADR 0008 § 6. 4 panels (quota / 24h request stats / 30d SVG sparkline / top fallback chains). Vanilla HTML+JS+fetch (no build step). 30s page poll with document.visibilityState pause. Served by /dashboard route owner-only_block.
bin/olp-audit-rotate.mjs	✅ Phase 3 shipped (D52)	External audit rotation cron tool per ADR 0008 § 5.2. npx olp-audit-rotate [--olp-home=<path>]. Idempotent + safe alongside the in-server first-append trigger.
docs/provider-caveats.md	📋 Planned (Phase 3+)	Lossy-translation reference; for now documented inline in each plugin header
docs/openai-spec-pin.md	✅ Shipped (D30)	OpenAI spec snapshot for annual audit; v0.1 baseline pinned 2026-05-24
docs/alignment-audits/	📋 Planned	Output directory for annual alignment audits (first audit: 2027-05-14)
scripts/migrate-from-ocp.mjs	📋 Planned (Phase 7)	OCP → OLP migration tool
setup.mjs	📋 Planned	Setup wizard / initial config

Known limitations

Behaviors that work correctly at personal/family scale but have ratified follow-ups for a v1.x sprint. Single landing page: docs/v1x-roadmap.md.

• Streaming-path singleflight ✅ shipped (D57 + D58, 2026-05-25). cacheStore.getOrComputeStreaming(...) mirrors the buffered-path getOrCompute and resolves the TOCTOU window between peek and spawn (issue #16). Two concurrent identical streaming requests share one CLI spawn via tee fan-out; late joiners receive accumulated replay + the live tail; per-client backpressure (PER_CLIENT_QUEUE_CAP=1MB) protects against slow consumers; full-disconnect aborts the source CLI via AbortController. New X-OLP-Streaming-Inflight: source | attached header annotates the role. New cache_status: 'streaming_attached' audit value tracks the singleflight win. Authority: ADR 0005 Amendment 8, v1.x roadmap #1.

• Soft triggers configured but inert. routing.soft_triggers in ~/.olp/config.json is honored by the engine's evaluation logic but quotaStatus() polling is not wired (ADR 0004 Amendment 2). A startup warning fires if the field is non-empty so the inert state is visible.

• Multi-key auth + owner gating + keygen CLI shipped at v0.2.0 (D44 + D45 + D46 + D47). lib/keys.mjs (core), lib/audit.mjs (audit), owner-vs-guest /health payload trimming + X-OLP-Fallback-Detail policy gating, bin/olp-keys.mjs (keygen CLI). All 11 ADR 0007 § 10 acceptance criteria covered. v0.2.0 maintainer-merged 2026-05-25.

• Phase 3 (Dashboard + audit query layer + rotation) shipped to main (D48-D54); v0.3.0 release pending. docs/adr/0008-dashboard-and-audit-query.md ratified at D48. lib/audit-query.mjs (D49) implements the 5-function aggregate query API (in-memory ndjson scan, PII-guarded). 4 new owner-only_block endpoints at D50 (/dashboard, /v0/management/dashboard-data, /v0/management/quota, /cache/stats). dashboard.html full multi-panel UI at D51 (vanilla HTML+JS+fetch, 30s poll with visibilitychange pause). Daily audit rotation at D52 (synchronous on first append after UTC midnight; audit-YYYY-MM-DD.ndjson naming) + optional bin/olp-audit-rotate.mjs cron tool. tried_providers schema semantic fix at D53 (D45 P2 deferral). Phase 3 close to v0.3.0 is maintainer-triggered per CLAUDE.md release_kit.phase_close_trigger.

  Bootstrap workflow (D47): for first-run / production setup:

  # 1. Generate an owner key (prints the plaintext token ONCE — capture it now)
  npx olp-keys keygen --owner
  
  # 2. Set production config (defaults to allow_anonymous: false)
  # (Edit ~/.olp/config.json to enable providers + chains as usual)
  
  # 3. Start the server
  npm start
  
  # 4. Validate the key works (substitute the captured plaintext token)
  curl -H "Authorization: Bearer olp_..." http://localhost:4567/health
  

  Recovery if owner token is lost: npx olp-keys keygen --owner --force revokes the previous owner key + creates a fresh one (plaintext printed once).

  New env vars consumed at D45: OLP_HOME (override ~/.olp/ location, used by tests + operator deployments); OLP_OWNER_TOKEN (synthetic env-owner identity for headless / CI deployments — bypasses filesystem manifest lookup with stable __env_owner__ keyId).

  New config block consumed at D45: config.json auth.{ allow_anonymous, owner_only_endpoints, fallback_detail_header_policy }. Default allow_anonymous: false (production-off); set true to accept requests without an OLP API key (development / single-user dev mode). Startup emits a warn when allow_anonymous: true so the relaxed posture is observable.

• Provider-level cacheKeyFields mask not implemented. Cache keys include every IR field including ones individual plugins drop at spawn (e.g., Anthropic plugin drops temperature). Spurious cache misses possible (extra spawn cost; never spurious hits). Conservative posture documented in ADR 0005 Amendment 7. Tracked in v1.x roadmap #5.

---

Architecture

OLP is a Node.js (ESM, .mjs) HTTP proxy with no build step and minimal dependencies. The high-level shape:

• Entry surface — server.mjs handles /v1/chat/completions and the administrative endpoints. Governed by OpenAI's /v1/chat/completions specification as the wire authority. See ALIGNMENT.md § Authorities.
• Intermediate Representation (IR) — lib/ir/ normalizes between the entry surface and provider-native shapes. The IR is the lingua franca; any extension is an ADR 0003 amendment.
• Provider plugins — lib/providers/<name>.mjs. Each plugin implements the contract in ADR 0002 (Plugin Architecture for Providers), spawns its CLI, and translates between IR and provider-native IO.
• Cache layer — lib/cache/ is a content-addressed cache keyed on the 11-field tuple defined in ADR 0005 § "Cache key composition (v1.0)" (provider, model, messages, tools, temperature, response_format, cache_control, max_tokens, top_p, stop, tool_choice — as of Amendment 2/D15). Per-key isolation, prompt-caching bypass, chunked stream replay, and singleflight. See ADR 0005 (Cache Layer Cross-Provider Design). Current backing store is an in-memory Map; file-backed storage is planned for Phase 2.
• Fallback engine — lib/fallback/ advances a configured chain one provider at a time on configured triggers, never retrying after the first response chunk has been emitted to the client. See ADR 0004.
• Multi-key auth — lib/keys.mjs (📋 planned, Phase 2) will carry OCP's per-OLP-key namespace isolation forward. Each OLP API key will have independent quota, cache namespace, and audit log; each key declares which providers it can access.

Read the ADRs in docs/adr/ in order before proposing structural changes.

Phase plan

OLP lands in phases. Each phase has its own PR series and Iron-Rule-10 reviewer; this README's placeholders are filled per-phase via the release_kit overlay.

The original v0.1 spec (in ~/.cc-rules/memory/projects/olp_v0_1_spec.md on the maintainer's workstations) planned one provider plugin per phase. The actual Phase 1 execution bundled the three Tier-D provider plugins + cache layer + fallback engine into a single shipped milestone (v0.1.0) followed by a cleanup batch (v0.1.1). The phase numbering below reflects what was actually shipped, not the original per-plugin partition.

• Phase 0 — Repo bootstrap, ALIGNMENT.md, founding ADRs, CI workflows, PR template. ✅ Shipped (2026-05-23).
• Phase 1 — Multi-provider proxy core: server.mjs, IR, three Tier-D provider plugins (Anthropic / OpenAI Codex / Mistral Vibe), cache (D1+D4) + cleanup (D2 bypass / D3 chunked replay / D23 size cap), fallback engine with first-chunk safety + hard triggers + per-hop log observability, IR↔OpenAI translation under Rule 2(b). ✅ Shipped — v0.1.0 (2026-05-24) + v0.1.1 cleanup (2026-05-25, D35–D42).
• Phase 2 — Multi-key auth (lib/keys.mjs) per ADR 0007: opaque OLP API keys, per-key cache namespacing, owner-vs-guest tier for header gating, audit ndjson (lib/audit.mjs), /health payload trimming + X-OLP-Fallback-Detail emission gating, OLP_OWNER_TOKEN env override, keygen CLI (bin/olp-keys.mjs). ✅ Shipped — v0.2.0 (2026-05-25, D43-A → D47). All 11 ADR 0007 § 10 acceptance criteria covered.
• Phase 3 — Dashboard + audit query layer + daily audit rotation per ADR 0008: in-memory ndjson aggregate query layer (lib/audit-query.mjs), 4 owner-only_block management endpoints (/dashboard + /v0/management/dashboard-data + /v0/management/quota + /cache/stats), multi-panel dashboard.html with 30s poll, synchronous daily audit rotation + bin/olp-audit-rotate.mjs cron tool, tried_providers schema fix (D45 P2 deferral). ✅ Shipped — v0.3.0 (2026-05-25, D48 → D54). All 15 ADR 0008 § 10 acceptance criteria covered.
• Phase 4 (planned) — Per-key per-provider auth artifact mapping (ADR 0007 § 12 deferral), audit query rotation/retention policies, SQLite hybrid migration (ADR 0007 § 13 trigger), provider-cost weights for spend trend.
• Phase 4+ (v1.x roadmap, triggered as needed) — Full deferred-work tracker: docs/v1x-roadmap.md. Includes streaming-path singleflight (issue #16 + ADR 0005 Amendment 8 design ratified), soft-trigger reactivation (ADR 0004 Amendment 2), /health activeSpawns integration, provider-level cacheKeyFields mask, streaming-path SPAWN_FAILED salvage.
• Phase N (opt-in) — Tier-2 / Tier-C provider plugins (Grok / Kimi / MiniMax / GLM / Qwen) per ADR 0006; provider-native protocol endpoints; deterministic triggers. Triggered by tier-2 demand, not on the bootstrap path.

Full spec (decision rationale, open questions, risks): ~/.cc-rules/memory/projects/olp_v0_1_spec.md on the maintainer's workstations. Phase 2 kickoff handoff: ~/.cc-rules/memory/handoffs/2026-05-25-phase-2-kickoff.md.

Migration from OCP

placeholder — scripts/migrate-from-ocp.mjs lands with Phase 7 (📋 planned, not yet authored).

Anticipated user-facing flow (target: <5 minutes):

1. Stop OCP (launchctl bootout the OCP service or ocp stop).
2. Install OLP.
3. Run olp migrate-from-ocp — copies ~/.ocp/keys/ to ~/.olp/keys/ and points provider plugins at OCP's existing auth artifacts where applicable.
4. Start OLP. Clients pointing at port 4567 (or 3456 with OLP_PORT=3456) keep working; their existing OLP API keys remain valid. Note (v0.4.0+): default port moved from 3456 → 4567 so OCP and OLP can co-host during migration; set OLP_PORT=3456 if you want the pre-D60 default.

OCP's cache directory is not migrated: OLP's cache key format includes provider+model and warms cold naturally. OCP enters maintenance mode (stability fixes only) when OLP v0.1 ships; new development happens in OLP.

Acknowledgements

OLP evolved from OCP (Open Claude Proxy). OCP's per-key isolation model, cache-layer design (D1–D4), dashboard, and alignment-constitution discipline are all carried forward. The structural generalization from single-CLI to multi-provider is what makes this a new project rather than an OCP minor version — see ALIGNMENT.md § Reference: How OCP's cli.js discipline maps to OLP.
