* docs: D43-B — ADR 0007 multi-key auth design draft (design-only, no code change) Phase 2 mainline design ADR. Ratifies the storage / token / manifest / atomic-write / owner-gating / bootstrap / Node-baseline decisions ahead of D44+ implementation D-days. Pure design doc — no .mjs / no tests / 4 files touched. Test count 468 → 468. - docs/adr/0007-multi-key-auth.md (new, ~400 lines): 13 sections covering Context / Decision (Option 2 filesystem manifest + opaque token) / Storage layout / Manifest schema / Token format (olp_+32B base64url, SHA-256 hash) / Atomic write & audit append (manifest lifecycle-only atomic via tmpfile+fsync+rename; audit per-request append with warn+1-retry, no memory buffer at Phase 2) / Owner-vs- guest-vs-anonymous gating (config.json auth.allow_anonymous default false, no env auto-detection) / Audit ndjson schema (no PII) / Bootstrap & recovery (minimal keygen command surface + OLP_OWNER_TOKEN env override with stable __env_owner__ keyId) / Acceptance criteria (11 test surfaces) / Node baseline (Option 1 SQLite port rejection rationale citing engines >=18 + CI 20/24 vs node:sqlite v22.5.0/RC) / Out of scope (Dashboard, quota enforcement, audit query, file locking deferred to Phase 3+) / Future forward (Option 3 hybrid migration trigger + preconditions). - docs/adr/README.md index: added ADR 0007 row with one-paragraph summary covering storage choice + rejection rationale. - docs/v1x-roadmap.md #2: marked PHASE 2 ACTIVE (no longer deferred); "Design ADR (NOT YET RATIFIED)" → "Design ADR (ratified) → ADR 0007"; trigger updated to "already fired 2026-05-25"; code anchors pinned to exact line numbers (cache/store.mjs:77-79/:287, server .mjs:502/:531/:392/:1072/:1101). - CHANGELOG.md Unreleased: D43-B entry per release_kit overlay phase_rolling_mode discipline. Authority: - Phase 2 kickoff handoff (~/.cc-rules/memory/handoffs/2026-05-25-phase-2-kickoff.md, cc-rules d9da966) - OLP v0.1 spec § 4.5 (planning authority for ~/.olp/ layout) - OCP keys.mjs (prior-art for opaque-key + per-key isolation model) - Node node:sqlite docs (https://nodejs.org/api/sqlite.html — Option 1 rejection per ADR 0007 § 11) - CC 开发铁律 v1.6 § 10 — fresh-context opus reviewer required for design ADR per Iron Rule 10 ALIGNMENT.md scope check: this PR introduces a new ADR; per ALIGNMENT.md Rule 1 (Cite First), the ADR itself contains the authority citations its decisions rest on (v0.1 spec § 4.5, OCP keys.mjs, Node docs URL). No provider plugin / entry surface / IR change in this commit. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * docs: D43-B fold-in — ADR 0007 reviewer findings (2 P2 + 3 P3, all polish) Fresh-context opus reviewer (PR #19) returned APPROVE_WITH_MINOR with 2 P2 load-bearing-but-non-blocking findings + 3 P3 polish findings. All five are accepted as suggested; design contract clarified without semantic change. - § 6.2 step 1 (P2 #1) — pin audit serialization to fire AFTER status_code is determined and latency_ms is measured. Makes acceptance criterion #2 (anonymous-401 audit event records the 401 + latency) testable in the way the criterion was written. - § 6.3.5 (P2 #2, new subsection) — explicit "Token validation MUST hit the manifest on every authenticated request (no in-process validation cache at Phase 2)" rule. The acceptance criterion #6 (post-revoke 401 within the next request) was previously enforced only by the test; the rule now belongs to the design contract. Forward-path note documents when a Phase 3+ amendment may add a cache. - § 6.1 atomic-write step 5 follow-up (P3 #3) — document the deliberate omission of directory fsync after rename. Single-process family-scale deployment accepts the tiny rename-loss window under abrupt host crash; future POSIX-strict deployments know where to add the step. - § 9.4 (P3 #4) — declare token-collision between OLP_OWNER_TOKEN and a filesystem-stored key's plaintext as undefined behaviour. Operators MUST NOT reuse plaintext across both surfaces. Phase MAY add startup collision-detection later. - § 10 criterion #4 (P3 #5) — rephrased to assert against the config- driven owner_only_endpoints predicate rather than a hardcoded trimmed payload shape. The test stays stable if an operator removes /health from owner_only_endpoints. CHANGELOG D43-B entry: fold-in bullet added to summarize the 5 fixes. Test count: 468 → 468 (npm test verified locally after fold-in). Authority: PR #19 fresh-context opus reviewer findings; CLAUDE.md release_kit overlay phase_rolling_mode — under Unreleased. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * docs: D43-B fold-in #2 — maintainer text-review findings (1 P1 + 1 P2 + 1 P3) Maintainer (codex) did final text review of PR #19 against the Phase 2 ADR-ratification checklist. Returned 3 findings; all accepted as suggested. Two are contract-level (P1 safety + P2 factual); one is trivial (P3 line-count drift). No semantic change beyond what the findings called out. P1 — § 6.3 / § 6.4 / § 10 #7 — revoke-dominates-touch safety contract Original § 6.3 said touchLastUsed used the same atomic-write pattern as 6.1; § 6.4 said concurrent CLI revoke + touchLastUsed left "both states valid" with "observability-grade" failure mode. Codex correctly identified the bug: a stale manifest snapshot held by the touch path could overwrite a fresh revoke and silently clear revoked_at back to null, breaking acceptance criterion #6 (post-revoke 401 within next request) under concurrent CLI revoke + in-flight server request. The ADR was promising security-grade behavior on a path that was actually last-write-wins. Fix: - § 6.3 rewritten with explicit read-modify-write discipline: touch MUST re-read latest manifest from disk inside the per-key write-lock, NO-OP if revoked_at is non-null, otherwise merge last_used_at preserving all other fields including revoked_at. - § 6.4 reframed from "both states valid" to "revoke dominates touch" safety frame, citing § 6.3 as the load-bearing discipline. The CLI revoke writer always wins the dimension that matters; touch may lose its last_used_at update if it raced. - § 10 criterion #7 expanded to test all three orderings (revoke -> touch, touch -> revoke, interleaved) with the explicit MUST: revoked_at is non-null and equals the revoke writer's timestamp after any interleaving; FAIL if any path produces revoked_at: null. - Forward-path § 6.4 file-locking note updated to clarify §6.3 already holds the contract single-process; flock adds defense-in- depth for rare multi-writer TOCTOU. P2 — § 11 forward path step (1) — Node baseline version history corrected Original wording "Node v22.5.0+ for unflagged but RC; Node TBD for stable" was wrong. v22.5.0 added with --experimental-sqlite flag; v22.12 still required the flag; the module moved past flag-gating in v22.13.0 (LTS) / v23.4.0 (current); entered Release Candidate at v25.7.0 per current docs. Fix: § 11 forward path step (1) rewritten with accurate versions + two Node release-history URLs cited (https://nodejs.org/download/ release/v22.12.0/docs/api/sqlite.html and https://nodejs.org/api/ sqlite.html). Minimum non-flag-gated baseline is now stated as >=22.13.0 (LTS) / >=23.4.0 (current); stable baseline TBD pending Node v25.x+. The rejection-evidence paragraph earlier in § 11 ("v22.12 still required --experimental-sqlite ... current docs mark RC") was already correct and is untouched. P3 — CHANGELOG D43-B line-count corrected Entry said ADR was "~270 lines"; actual file is 420 lines after both fold-ins. Changed to "~420 lines after fold-ins". Phase 2 fold-in #2 bullet enumerates the 3 fixes in this commit; fold-in #1 bullet retained for the opus reviewer round. Test count: 468 / 468 (npm test verified locally after fold-in; design-only doc changes, no test file touched). Authority: PR #19 maintainer text review findings 2026-05-25; CLAUDE.md release_kit overlay phase_rolling_mode — under Unreleased; Node SQLite docs URLs cited in ADR § 11 forward path.

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. |
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.
