taodengandClaude Opus 4.7 8fd8f86942 release(phase-1-cleanup): v0.1.1 — pre-Phase-2 batch (D35-D42)
Phase 1 cleanup release per CLAUDE.md release_kit.phase_rolling_mode
policy. Closes 16 of 17 pre-Phase-2 GitHub issues; #16 stays OPEN as
v1.x tracker with design ratified in ADR 0005 Amendment 8.

Bumps package.json from 0.1.0 → 0.1.1. Promotes CHANGELOG "Unreleased"
section to "## v0.1.1 — 2026-05-25" with full D35-D42 entries
(backfilled D35/D36/D37 entries per cold-audit round 7 Finding 1) and
final cleanup batch summary covering all 8 D-day commits that landed
on `main` between 2026-05-24 and 2026-05-25.

Tag v0.1.1 will be pushed after this commit lands and CI is green.
release.yml auto-creates the GitHub Release from the CHANGELOG v0.1.1
section (extracted via awk pattern match on `## v0.1.1` heading).
D37's phase_rolling_mode gate now passes because Unreleased is
sentinel-only after this commit.

**What v0.1.1 delivers (D35-D42):**

- D35 — streaming empty-stream headers (#9) + truncation marker (#10)
  + irVersion strict check (#11) + alignment.yml scripts/** removal
  (#12) + X-OLP-Latency-Ms uniform audit (#4)
- D36 — cache_control partial-noop log (#2) + ADR 0002 filename
  correction (#5) + mistral A5 flip (#6) + /v1/models alias governance
  (#13) + cache_control determinism test (#14) + anthropic v2.1.89
  transcript artifact (#15)
- D37 — release.yml phase_rolling_mode CI gate (#17)
- D38 — maxConcurrent runtime enforcement + new CONCURRENCY_LIMIT
  hard trigger (#1)
- D39 — CacheStore.delete + cache_evicted_truncated log + sticky-
  cache regression test + SPAWN_TIMEOUT asymmetry ADR (#3)
- D40 — X-OLP-Fallback-Detail debug header + per-hop tuple collection
  + 4KB cap + RFC 7230 non-ASCII escape (#7)
- D41 — X-OLP-Provider-Used chain-origin semantics documented (#8)
- D42 — streaming singleflight v1.x design ADR + multi-layer
  safeguards (issue #16; STAYS OPEN as v1.x tracker)

**Test growth:** 416 (v0.1.0) → 468 (v0.1.1). +52 tests across the
8 D-day batch. All 468 pass at the release-commit head.

**Cold-audit cycle:** 1 final round (round 7) over D35-D42 + v0.1.0
state. Result: PASS_WITH_MINOR with 4 findings (1×P3 + 3×P4).
- Finding 1 (P3 CHANGELOG missing D35/D36/D37) — FIXED in this commit
  via backfill.
- Finding 2 (P4 ADR 0005 Amendment 8 "Amendment 1/3/5" notation
  ambiguity) — FIXED in this commit (replaced with explicit
  § Decision body item-1 + Amendment 3 + Amendment 5 wording).
- Finding 3 (P4 ADR 0005 Amendment 8 Context paragraph cites line 811
  but actual branch is at lines 817-823) — FIXED in this commit
  (Context paragraph now points at lines 817-823 with the TODO anchor
  at ~810 as the navigable landmark).
- Finding 4 (P4 ADR 0002 missing Amendment 2 — pre-existing gap)
  — FIXED in this commit (added explanatory note under the
  Amendments heading explaining the gap is intentional and load-
  bearing).

No P1 or P2 findings.

**Phase 1 cleanup release_kit checklist** (per CLAUDE.md):
- [x] All 8 D-day deliverables landed on main (D35-D42)
- [x] CI green on every D-day commit + on this release commit's head
- [x] Cold-audit round 7 PASS_WITH_MINOR (0 P1/P2; 4 findings all
  fixed in this commit)
- [x] 16 of 17 pre-Phase-2 GitHub issues closed (#1-#15 and #17);
  #16 stays OPEN as v1.x tracker with design ratified
- [x] Issue #16 status comment posted (D42 commit b0c080d)
  referencing ADR 0005 Amendment 8 design ratification
- [x] CHANGELOG "Unreleased" promoted to "## v0.1.1 — 2026-05-25"
  with D35-D42 entries (including backfilled D35/D36/D37)
- [x] package.json bumped from 0.1.0 → 0.1.1
- [x] docs/v1x-roadmap.md created at D42 — 7 deferred items with
  code anchors + GitHub-issue cross-refs + concrete start triggers
- [x] Editorial findings 2/3/4 from round 7 folded into this commit
- [ ] Tag pushed (next step in this PR's lifecycle)
- [ ] release.yml triggered + GitHub Release created (auto on tag
  push; D37 phase_rolling_mode gate will pass because Unreleased
  is now sentinel-only — gate dry-run verified locally)

**Known limitations carried to v1.x:** full list with code anchors
+ start triggers in docs/v1x-roadmap.md. The 7 items are:
1. Streaming-path singleflight (issue #16, ADR 0005 Amendment 8)
2. Multi-key auth (lib/keys.mjs)
3. Soft-trigger reactivation (ADR 0004 Amendment 2)
4. /health activeSpawns integration (ADR 0002 Amendment 6)
5. Provider-level cacheKeyFields mask (ADR 0005 Amendment 7)
6. Streaming-path SPAWN_FAILED salvage
7. D40 AUTH_MISSING tuple test coverage

Authority:
- All 8 D-day commit messages (D35-D42 on main)

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.

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.
