68e50da68a fix+test+docs: D53 — tried_providers schema semantic fix (D45 P2 deferral closed) (#30)
Sixth Phase 3 D-day. Small focused fix for the D45 fresh-context opus
reviewer P2 finding that was deferred: auditCtx.tried_providers on the
key_no_provider_access 403 path was being stamped with the ORIGINAL
chain (which was filtered out, never dispatched), distorting downstream
audit queries like "which providers did key X actually call".

CHANGES:

  - server.mjs handleChatCompletions ~L815: on key_no_provider_access
    403, auditCtx.tried_providers = [] (was _originalChainProviders).
    The configured-but-blocked chain still appears in the human-
    readable error message body — the audit just doesn't claim those
    providers were "tried" when the server's filter dispatched zero.

  - docs/adr/0007-multi-key-auth.md § 8 amendment: new paragraph
    spelling out the tried_providers semantic. "The list of providers
    the server actually dispatched a spawn against. A provider that
    was configured in the chain but filtered out by providers_enabled
    gating is NOT included — the key didn't try the provider, the
    gate did. On the 403 path tried_providers is the empty array."
    Plus a forward note that audit log rotation moved to Phase 3 /
    ADR 0008 § 5.

  - test-features.mjs Suite 20h-extra-audit (+1 test — 600 → 601):
    creates guest key with providers_enabled: ['mistral']; fires
    request for Anthropic-routed model; asserts 403
    key_no_provider_access; reads audit row from audit.ndjson;
    asserts tried_providers === []. Pins the D53 semantic against
    regression.

  - CHANGELOG.md: D53 entry under Unreleased.

NOT IN D53:

  - E2E + docs polish (D54)
  - Phase 3 close → v0.3.0 (D55; maintainer-triggered)

Test count: 600 → 601 (+1). Verified locally via npm test.

AUTHORITY:

  - ADR 0007 § 8 amendment (D53, 2026-05-25).
  - D45 fresh-context opus reviewer P2 deferral note.
  - CLAUDE.md release_kit overlay phase_rolling_mode — under Unreleased.
  - Standing autopilot grant.

ALIGNMENT.md scope check: small entry-surface change (audit context
field assignment on one error path) + ADR amendment + new test. Per
ALIGNMENT.md Rule 1 the ADR amendment is the authority citation for
the server change. No provider plugin / IR / models-registry 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).

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.
