c0b696984f docs: D48 — ADR 0008 Phase 3 design draft (Dashboard + audit query layer) (#25)
* docs: D48 — ADR 0008 Phase 3 design draft (Dashboard + audit query layer, design-only)

First Phase 3 D-day. Design-only. Ratifies the storage / query model /
rotation / dashboard / refresh / scope decisions ahead of D49+
implementation D-days. Opens ADR 0007 § 12 deferral for Dashboard +
audit query layer + rotation.

NEW docs/adr/0008-dashboard-and-audit-query.md (~368 lines): 13 sections
+ Consequences + Authority citations. Per maintainer-pinned lanes
A/A/B/A/B from Phase 3 kickoff brief 2026-05-25:

  Lane 1 (tech stack): A — static HTML + vanilla JS + fetch; no build
    step; matches OLP "no bundler" ethos.
  Lane 2 (query model): A — in-memory scan of audit ndjson per request;
    O(N) per call; family-scale acceptable; defers SQLite hybrid to
    Option 3 trigger per ADR 0007 § 13 (requires engines bump as
    separate prior PR).
  Lane 3 (rotation): B — daily rotation, audit-YYYY-MM-DD.ndjson on
    first append after UTC midnight + optional bin/olp-audit-rotate.mjs
    external cron.
  Lane 4 (refresh): A — 30s page poll (no SSE infra at v0.3.0;
    pause when document.visibilityState is hidden).
  Lane 5 (dashboard scope): B — full per spec § 4.6: 4 panels (per-
    provider quota / 24h request+cache+fallback / 30d spend trend /
    top-N fallback chains).

ADR sections:

  §1 Context (what Phase 3 closes; what stays out)
  §2 Decision (5 lanes pinned)
  §3 Storage layout (~/.olp/logs/ with rotated date files)
  §4 lib/audit-query.mjs API (readAuditWindow, aggregateRequests,
     topFallbackChains, spendTrendDaily, cacheHitRateWindow)
  §5 Audit rotation (first-append-after-UTC-midnight trigger + cron
     alternative + concurrent-safety per-process lock)
  §6 Dashboard panels (4 panels per spec § 4.6, refresh + localhost-
     bound notes)
  §7 Server endpoints (/dashboard, /v0/management/dashboard-data, /v0/
     management/quota, /cache/stats — owner-only gated)
  §8 Auth gating (reuses ADR 0007 § 7 owner_only_endpoints config)
  §9 Failure modes + degradation (per-panel error states)
  §10 Acceptance criteria (15 testable items for D49-D54)
  §11 Forward path (Phase 4+ — SQLite migration, SSE push, key-mgmt UI)
  §12 Out of scope (explicitly NOT in Phase 3)
  §13 Phase 3 sprint shape (D48-D55)

CHANGED:

  - docs/adr/README.md: added ADR 0008 row with one-paragraph summary.
  - CHANGELOG.md Unreleased: D48 entry per release_kit overlay
    phase_rolling_mode discipline. Includes Phase 3 sprint shape table.

NOT IN D48 scope:

  - lib/audit-query.mjs (D49)
  - server.mjs endpoints (D50)
  - dashboard.html (D51)
  - lib/audit.mjs rotation extension + bin/olp-audit-rotate.mjs (D52)
  - tried_providers schema fix (D53; D45 P2 deferral)
  - Phase 3 close (D55; v0.3.0; maintainer-triggered)

Test count: 544 / 544 pass (design-only, no test change). Verified
locally via npm test before commit.

AUTHORITY:

  - ADR 0007 § 12 (opens Phase 3 Dashboard + audit query deferral).
  - ADR 0007 § 13 (rejects SQLite at Phase 3 per Node baseline +
    documents forward-path trigger).
  - OLP v0.1 spec § 4.6 + § 4.7 (Dashboard + observability endpoints
    planning authority).
  - OCP dashboard.html (prior-art reference for multi-panel HTML
    structure).
  - ADR 0002 (Provider.quotaStatus contract — Panel 1 data source).
  - ADR 0005 § Cache stats (/cache/stats endpoint pre-existing design).
  - CC 开发铁律 v1.6 § 10 — fresh-context opus reviewer required for
    design ADR.
  - Phase 3 kickoff via maintainer "go" 2026-05-25 + standing-autopilot
    grant (~/.cc-rules/memory/auto/standing_autopilot_phase_2.md in
    cc-rules bf0ed9a — Phase 3+ requires new authorization; the "go"
    supplied that).

ALIGNMENT.md scope check: this PR introduces a new ADR with full
authority citations per Rule 1 (Cite First). No provider plugin /
entry surface / IR change in this commit.

* docs: D48 fold-in — opus reviewer findings (1 P2 + 2 P3, all ADR-text polish)

Fresh-context opus reviewer (PR #25) returned APPROVE_WITH_MINOR with 3
findings, all ADR-text polish. No design semantic change beyond the
clarifications.

P2 — § 8 + § 10 #9 gating-mode wording

  Original § 8 implied a new "block non-owner identities" behaviour
  without naming it; § 10 #9 tested only the universal
  allow_anonymous: false 401 case. Fix:
  - § 8 now formalizes two gating modes — owner_only_trim (Phase 2
    /health pattern) vs owner_only_block (new Phase 3 management-
    endpoints pattern) — and explains the management endpoints are
    owner_only_block because the entire payload is sensitive.
  - § 10 #9 now covers both 401 paths: (a) allow_anonymous: true
    + no header → anonymous identity → STILL 401 because management
    endpoints are owner_only_block; (b) allow_anonymous: false + no
    header → 401 at the authenticate middleware itself.

P3 #1 — /cache/stats citation accuracy

  Original § 7.4 + Authority block cited "ADR 0005 § Cache stats"
  which is not a real section. Corrected: planning authority is OLP
  v0.1 spec § 4.6; ADR 0005 references the endpoint in
  Consequences/Mitigations (~line 279) for the per-(provider, model)
  cache-hit-rate breakdown surface.

P3 #2 — cacheStore.stats() shape gap

  § 7.4 now explicitly acknowledges the current shape
  ({ hits, misses, size, inflightCount } global aggregate) lacks the
  per-(provider, model) breakdown spec § 4.6 implies; Phase 3 Panel 2
  sources per-provider counts from aggregateRequests (audit-side)
  instead. If a future panel needs the breakdown, D50 amends the
  store shape + an ADR 0005 amendment fires at that time. Phase 3
  acceptance criteria do not require the breakdown.

CHANGELOG.md Unreleased D48 entry: fold-in bullet added enumerating
the 3 fixes.

Test count: 544 / 544 pass (design-only, no test change). Verified
locally via npm test.

Authority: PR #25 fresh-context opus reviewer findings; CLAUDE.md
release_kit overlay phase_rolling_mode — under Unreleased.

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).

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 ~150250 lines; longer than that, split.
