10 README install gaps catalogued and fixed in one D-day after v0.4.2's PI231 E2E session exposed that the v0.4.0-v0.4.2 README Quick Start was fictional (npm package isn't published; olp setup/start commands don't exist). F5 (OLP_BIND env) ships in the same patch so the documented LAN onboarding flow actually works. AI-driven install prompt added per Phase 4 charter brainstorm Top-5 inheritance candidate #2 (D64-D67 built the doctor framework; D76 closes the README half). ## G1-G7: README Quick Start now real Rewrote § "Manual install" from placeholder text to the empirically-verified sequence: - Prerequisites (Node >= 18 + provider CLI install matrix) - git clone + npm test verify - olp-keys keygen --owner FIRST (allow_anonymous=false default needs a key) - Per-provider OAuth (claude setup-token / codex login --device-auth / MISTRAL_API_KEY) - ~/.olp/config.json with the minimum that actually serves traffic - npm start - Smoke-test via curl + olp doctor - IDE pointing ## G8 / F5: OLP_BIND env shipped server.mjs: - const BIND = process.env.OLP_BIND ?? '127.0.0.1' (safe default unchanged) - server.listen(PORT, BIND, ...) replaces hard-coded '127.0.0.1' - New startup warn anonymous_key_advertised_with_lan_bind fires when OLP_BIND is non-loopback AND auth.advertise_anonymous_key: true (operator visibility into trust-context overlap) Pre-D76 the server only accepted loopback connections, so the documented olp-connect <ip> family-onboarding flow was unreachable from LAN without SSH tunneling. F5 makes ADR 0011 operational instead of aspirational. ## G10: AI-driven install prompt README § "Install with your AI (the fast path)" — verbatim prompt the operator pastes into Claude Code / Cursor / Copilot / Aider. The AI follows README + uses olp doctor --json next_action.ai_executable[] for self-repair, stopping only when human_required[] is non-empty (provider OAuth dances). Closes the Phase 4 brainstorm #2 inheritance candidate. ## Opening compressed § "Why OLP" (3 paragraphs of Anthropic 2026-06-15 billing history) removed from the top. The OCP-trigger context moved to § "Migration from OCP" at the bottom, condensed into a single paragraph. New users land on value-prop + § "What you get" + install paths without needing to digest 2026-05-14 billing history first. OCP users get a one-line pointer at the top. ## Configuration + Env Variables sections updated - § Configuration: placeholder replaced with full ~/.olp/config.json schema documentation, every field cross-referenced to its ADR - § Environment Variables: added OLP_BIND, OLP_API_KEY, OLP_OWNER_TOKEN, OLP_PROXY_URL rows that were used in the manual-install flow but previously undocumented ## ADR 0011 § Deployment configurations amendment Codifies the three deployment trust contexts: - 127.0.0.1 (loopback only) — safe with any auth posture - RFC1918 / tailnet / specific LAN IP — anonymous_key OK (the documented trusted-LAN zero-config family onboarding flow) - Public IP — incompatible with advertise_anonymous_key: true Documents the new anonymous_key_advertised_with_lan_bind startup warn event. Closes ADR 0011's pre-D76 dangling reference to a non-existent BIND_ADDRESS concept. ## Test count 714 (v0.4.2) -> 717 (v0.4.3). +3 D76 regression tests in Suite 36 (36s/36t/36u) pinning OLP_BIND wiring + safety warn + ADR amendment. ## Process learning Every D-day reviewer rubric should add "open README §-Quick-Start and verify the commands literally exist + work in the current repo" — would have caught G1-G7 at v0.4.0 close. Combined with D74 (review-against-spec) + D75 (review-without-deployment), D76 (review-without-following-README) codifies the third tier of review discipline. ## Out of D76 scope (deferred) - F6 (doctor client-side vs server-side check separation) — needs design ADR for --remote mode. Phase 5. - D75 reviewer P2-1 (ADR 0004 per-hop schema amendment) + P2-2 (defensive typeof hopModel === 'string') — both genuine follow-ups, neither blocking. - scripts/migrate-from-ocp.mjs — Phase 7.

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). |
| 0011 | Anonymous-Key Deployment-Context Limits (Trusted-LAN Invariant) | D70 (2026-05-26, Accepted). Codifies the trust posture for /health.anonymousKey opt-in field (D69) + bin/olp-connect zero-config consumer (D68). Three-prerequisite gate (auth.advertise_anonymous_key=true + auth.allow_anonymous=true + an active key with plaintext_advertise field). Guest-tier-only restriction (createKey() + CLI reject owner+advertise). Trusted-LAN deployment invariant (loopback / RFC1918 / tailnet / .local / .internal — soft constraint at v0.4.0; hard enforcement deferred until OLP gains a public-deployment recipe). Re-evaluation trigger: any "expose to public internet" README mode. |
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.
