* feat+docs: D60 — Phase 4 charter (ADR 0010) + default OLP_PORT 3456 → 4567 Opens Phase 4 (Operator + Client UX) end-to-end. Per release_kit.phase_rolling_mode, the version bump fires at Phase 4 close (v0.4.0), not at this D-day; D60 only ships governance + the port default change. ## ADR 0010 — Phase 4 Charter Phase 4 scope = 5 D-day groups (~13 D-days total): - D60 (this commit): charter + default port - D61-D63: SSE heartbeat + recentErrors[20] ring + /status combined endpoint - D64-D67: olp Node-based CLI scaffold + olp doctor next_action framework - D68-D70: olp-connect zero-config IDE setup + /health.anonymousKey + ADR 0011 - D71-D73: olp-plugin/ OpenClaw gateway plugin + docs/integrations/*.md bundle Charter records the EXPLICIT DECISION to DEFER /v1/messages (Anthropic-shape entry surface) on the rationale: under ADR 0009 P0 failure it provides no billing benefit AND degrades worse on fallback than OpenAI-shape clients (because OpenAI tool schema is the cross-provider lingua franca; Anthropic- specific features cache_control / computer_use / text_editor / thinking blocks have no clean fallback mapping). Re-open trigger: (a) ADR 0009 P0 success AND (b) maintainer-named family CC user. README posture updated: Claude Code listed as NOT SUPPORTED as an OLP client; recommended alternative is "Cline + OLP" (same fallback chain available, better cross-provider compatibility). ## Default port 3456 → 4567 server.mjs:74 default value moves so OLP and OCP (which stays on 3456) can co-host on the same machine without OLP_PORT env override. Existing deployments wanting the pre-D60 default can set OLP_PORT=3456 in launchd plist / shell env. Verified port-change invariants: - All test-features.mjs suites use port: 0 (ephemeral) — 0 test-surface impact - Cache / fallback / provider plugins port-agnostic - Dashboard 30s poll + management endpoints use relative paths - 623/623 tests pass on D60 branch HEAD ## ADR amendments - ADR 0001 § "Decision" port-conflict paragraph: struck + amended (co-host is now possible via 3456 → 4567 + launchd labels dev.olp.proxy vs dev.ocp.proxy) - ADR 0008 § 6.6 default-port reference updated - docs/adr/README.md index gains ADR 0010 row ## Authority - ADR 0010 (this commit) - ADR 0009 (interactive-mode placeholder — /v1/messages defer rationale) - 2026-05-26 brainstorm: OCP comprehensive feature audit (subagent output) + multi-provider proxy / IDE integration prior-art survey (subagent output, both this session) - docs/v1x-roadmap.md (Phase 4 was the named destination) - CLAUDE.md release_kit.phase_rolling_mode (current_phase already Phase 4; this charter formalizes contents) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix: D60 reviewer P2-1 — soften ADR 0001 launchd-label assertion to forward-tense Reviewer flagged the ADR 0001 amendment's launchd-label collision claim ("avoided via dev.olp.proxy vs dev.ocp.proxy") as present-tense fact when the OLP plist generator hasn't shipped yet (lands D64-D70 per ADR 0010). Soften to forward-tense with explicit cross-reference. The factual claim ("co-host is possible") still stands because plist label is controlled by the OLP project anyway; this is precision, not correction. P2-2 (README "since v0.4.0" forward-dated branding) explicitly accepted as prior-art-consistent with D44+ Phase 2 mid-window doc conventions — no change.

Architecture Decision Records — OLP
This directory holds the OLP Architecture Decision Records (ADRs) — short documents that capture the why behind structural choices.
Read these before proposing governance, plug-in contract, IR, fallback, cache, or provider-inclusion changes.
Numbering
ADRs in OLP start at 0001 (the project's founding decision). OLP did not inherit the 0001 placeholder convention OCP used; the project starts on a fresh numbering line.
New ADRs increment from the highest existing number. Filenames are NNNN-<short-slug>.md.
Index
| ADR | Title | What it covers |
|---|---|---|
| 0001 | Project Founding | Why OLP exists (the 2026-06-15 Anthropic billing-split trigger), mission + non-mission boundaries, explicit supersession of OCP ADR 0005 "No Multi-Provider". |
| 0002 | Plugin Architecture for Providers | The lib/providers/<name>.mjs plug-in model, the Provider contract (name / models / auth / spawn / estimateCost / quotaStatus / healthCheck / hints), static in-tree registry, why-not full external plugin discovery. |
| 0003 | Intermediate Representation (IR) Design | The OLP-internal canonical request/response shape between the OpenAI-compat entry surface and each provider plugin. v1.0 IR fields, IR-vs-OpenAI-vs-native-provider three-shape model, IR is not exposed externally. |
| 0004 | Fallback Engine Semantics & Safety | Trigger taxonomy (Hard / Soft / Deterministic-deferred / Cost-aware-deferred), idempotent-failure safety (first-chunk rule), chain advancement one-at-a-time, observability headers. |
| 0005 | Cache Layer Cross-Provider Design | Cache key composition over (provider, model, messages, …), per-model isolation, D1+D2+D3+D4 port from OCP v3.13.0, cross-provider fallback cache behaviour (correct miss). |
| 0006 | Provider Inclusion / Exclusion + Risk-Tier Framework | The 4-tier classification (A excluded by default / B explicit consent / C opt-in / D eligible-for-default-enabled), Candidate-vs-Enabled distinction, current v0.1 candidate inventory (0 Enabled), Antigravity exclusion rationale (named prohibition + no cost advantage + reinstatement friction; pending primary-source pin), consent UX, future provider addition procedure. |
| 0007 | Multi-Key Auth (lib/keys.mjs) |
Phase 2 design ADR (D43-B, 2026-05-25). Option 2 (filesystem manifest at ~/.olp/keys/<key-id>/manifest.json) + opaque olp_<32-byte> token + SHA-256 hash. Owner / guest / anonymous tier gating with explicit config.json auth.allow_anonymous (default false). Bootstrap keygen command surface + OLP_OWNER_TOKEN env override with stable synthetic key_id. Audit ndjson append-only at ~/.olp/logs/audit.ndjson, warn+1-retry on append failure. Rejects direct SQLite port at v0.2.0 due to Node baseline (engines >=18 + CI 20/24 vs node:sqlite added 22.5.0 / RC); Option 3 hybrid documented as forward path when Phase 3+ Dashboard / SQL-aggregate quota arrives. |
| 0008 | Dashboard + Audit Query Layer | Phase 3 design ADR (D48, 2026-05-25). Static HTML dashboard + vanilla JS + fetch (no build step). In-memory ndjson scan for aggregate queries (O(N) per call; family-scale acceptable; defers SQLite migration to Option 3 hybrid trigger). Daily audit rotation audit-YYYY-MM-DD.ndjson on first append after UTC midnight; cross-file query layer for rolling 30-day windows. Owner-only gating on /dashboard + 3 /v0/management/* JSON endpoints reusing ADR 0007 § 7 auth model. 30s page poll (no SSE infra). Panels: per-provider quota / 24h request+cache+fallback / 30d spend trend / top-N fallback chains per spec § 4.6. Opens ADR 0007 § 12 Phase 3 deferral (Dashboard + audit query + rotation). |
| 0009 | Anthropic Interactive-Mode Path (Placeholder) | Placeholder ADR (2026-05-25, Draft) — blocked on OCP ADR 0007 P0 experiment outcome. Records the maintainer's "wait + port" decision: do NOT independently implement; ride OCP's P0 result. If P0 confirms Transport A (stdio NDJSON) or B (PTY) bills as subscription rather than Agent SDK credit, port to OLP lib/providers/anthropic.mjs (Option 1 parallel impl, or Option 2 OCP-as-backend; decision deferred to P0-resolution time). If P0 fails on both, shelve. No Phase 4 D-day scheduled until P0 lands AND maintainer issues explicit "go" naming this ADR. |
| 0010 | Phase 4 Charter — Operator + Client UX | Phase 4 scope ratification (2026-05-26, Accepted). Phase 4 = operator + client UX (SSE heartbeat / olp CLI + doctor / olp-connect zero-config + Telegram-Discord plugin + IDE docs bundle). ~13 D-days, D60 → v0.4.0. Records the explicit decision to DEFER /v1/messages (Anthropic-shape entry surface) on the rationale that under ADR 0009 P0 failure it provides no billing benefit AND degrades worse on fallback than OpenAI-shape clients. Re-open trigger: ADR 0009 P0 success + maintainer-named family CC user. Also closes the OCP-OLP port co-host ambiguity from ADR 0001 (default OLP_PORT 3456 → 4567). |
When to write a new ADR
Open one whenever:
- A structural rule is being added or changed (e.g., new IR field, new trigger type, new cache-key composition).
- A new provider plugin is being proposed (per ADR 0002 + ADR 0006 — ADR is a hard prerequisite for plugin merge).
- A decision encodes a lesson from an external event (provider policy change, drift incident).
- A future contributor reading the code alone could plausibly undo or re-litigate the choice.
Skip ADRs for routine implementation choices (algorithm pick, naming) — those belong in commit messages.
Format
Keep ADRs short — Context / Decision / Consequences / Alternatives is the standard skeleton. Cite incidents, PRs, or commits where useful. Length per ADR ~150–250 lines; longer than that, split.
