# Evaluation and benchmarks
+## v0.6.0 qualification and cost methodology
+
+The v0.6.0 qualification benchmark produces hash-verified latency, memory, origin-coalescing, and cost-savings evidence prior to the `1.0.0` stable API freeze.
+
+### Reproduce the qualification benchmark
+
+```bash
+mkdir -p /tmp/longcache-v03-baseline
+git archive e384615 | tar -x -C /tmp/longcache-v03-baseline
+LONGCACHE_TEST_REDIS_URL=redis://localhost:16379/0 uv run python -m evaluation.qualification_v6 \
+ --baseline-root /tmp/longcache-v03-baseline \
+ --smoke
+```
+
+For controlled reference-host release qualification:
+```bash
+LONGCACHE_TEST_REDIS_URL=redis://localhost:16379/0 uv run python -m evaluation.qualification_v6 \
+ --baseline-root /tmp/longcache-v03-baseline \
+ --release \
+ --reference-host-id
+```
+
+### Audited cost savings and net latency methodology
+
+LongCache evaluates cost and latency according to an audited mathematical model rather than arbitrary synthetic claims:
+
+1. **Net Cost per Request**:
+ $$\text{Net Cost} = (1 - h_{\text{useful}}) \cdot C_{\text{origin}} + C_{\text{infra}}$$
+ where $h_{\text{useful}}$ is the measured useful-hit rate under zero false hits, $C_{\text{origin}}$ is the provider token cost, and $C_{\text{infra}}$ is the amortized cache infrastructure cost.
+
+2. **Net Mean Latency**:
+ $$\text{Net Mean Latency} = h_{\text{useful}} \cdot L_{\text{hit}} + (1 - h_{\text{useful}}) \cdot (L_{\text{miss\_overhead}} + L_{\text{origin}})$$
+ where $L_{\text{hit}}$ is the local/network hit latency (10–25 ms), $L_{\text{miss\_overhead}}$ is the cache miss evaluation overhead (1–3 ms), and $L_{\text{origin}}$ is the provider response latency (600–1400 ms).
+
+3. **Break-Even Analysis**:
+ $$\text{Break-Even Hit Rate} = \frac{C_{\text{infra}}}{C_{\text{origin}}}$$

+
+### Added
+
+- **Multi-Process Redis Qualification & Stress Suite:** Added `tests/test_qualification_stress_v6.py` covering multi-worker write/delete/invalidate churn, 5-cycle transient connection outage/reconnect (`raise` vs `bypass`), volatile Redis restart / manifest-loss quarantine, and singleflight lease takeover under worker kill faults.
+- **Paged Vector-Only Rebuilds & Memory Bounds:** Implemented `iter_index_entries()` on `AbstractCacheBackend` (`SQLiteCacheBackend`, `RedisCacheBackend`, `SharedRedisCacheBackend`), streaming `(id, vector, metadata)` without loading large query/response payloads into RAM, bounding rebuild memory overhead.
+- **Bounded Local Stale-Vector Compaction:** Added `record_remote_invalidation()` to `SimilarityIndex` to compact stale local vectors when the orphan ratio reaches 25% (or 2,048 orphans) during sustained multi-instance write/delete churn.
+- **Automated Example & Quickstart Verification:** Added `scripts/wheel_examples_v6.py` and `tests/test_examples_and_migrations_v6.py` covering all 7 documented examples, README quickstarts, Format-1 legacy rejection, and Format-2 codec roundtrips (`json-v1`, `openai-dict-v1`, `openai-sdk-v1`).
+- **Reproducible Qualification & Cost Methodology:** Added `evaluation/qualification_v6.py` and `evaluation/cost_model.py` with reproducible benchmark budgets and an audited mathematical formula for net cost savings and break-even analysis across LLM model tiers.
+- **Release Verification & Rollback Runbook:** Added `scripts/verify_release_v6.py` to audit version synchronization, changelog entries, package metadata, and benchmark evidence hashes; documented PyPI Trusted Publishing and emergency yank procedures in `docs/release-process.md`.

+# Release Engineering & Rollback Runbook
+
+This runbook outlines the official process for cutting, verifying, and publishing releases of LongCache to PyPI, including release candidate procedures and emergency rollback/yank guidelines.
+
+---
+
+## 1. Release Lifecycle & SemVer Rules
+
+LongCache follows [Semantic Versioning 2.0.0](https://semver.org/):
+
+* **`0.x` Releases (`0.1.0` through `0.6.0`):** Fast-moving stabilization, qualification, and API cleanup. Breaking changes require documentation in `docs/migration-v0.x.md`.
+* **`1.0.0` Release:** The first frozen public API and support contract.
+* **`1.x.y` Releases:** Backward-compatible additions and patch fixes.
+* **Pre-releases (`0.6.0rc1`, `1.0.0rc1`):** Cut with an explicit validation window to allow downstream testing before official tags.
+
+---
+
+## 2. Pre-Release Checklist & Verification
+
+Before cutting any release tag or release candidate:
+
+1. **Clean Working Tree & Locked Dependencies:**
+ ```bash
+ uv sync --locked --extra all --extra dev --extra docs
+ ```
+2. **Lint, Format & Strict Typing:**
+ ```bash
+ make lint
+ make typecheck
+ ```
+3. **Full Test Suite & Redis Stress Checks:**
+ ```bash
+ export LONGCACHE_TEST_REDIS_URL=redis://localhost:16379/0
+ export LONGCACHE_TEST_MODEL=1
+ uv run --no-sync pytest tests/ -v --tb=short -rs
+ ```
+4. **All Documented Examples & Quickstarts:**
+ ```bash
+ uv run --no-sync python scripts/wheel_examples_v6.py
+ ```
+5. **Qualification Benchmark & Evidence Hash:**
+ ```bash
+ uv run --no-sync python -m evaluation.qualification_v6 \
+ --baseline-root /tmp/longcache-v03-baseline \
+ --smoke
+ ```
+6. **Documentation Build:**
+ ```bash
+ uv run --no-sync mkdocs build --strict
+ ```
+
+---
+
+## 3. Package Distribution & Integrity Checks
+
+Build and verify the distribution packages:
+
+```bash
+rm -rf dist/
+uv run --no-sync python -m build
+uv run --no-sync twine check --strict dist/*
+uv run --no-sync python scripts/check_package_metadata.py --dist-dir dist
+uv run --no-sync python scripts/verify_release_v6.py --dist-dir dist --check-evidence
+```
+
+This verifies:
+* `src/longcache/py.typed` is present in both `.whl` and `.tar.gz`.
+* No test cache artifacts (`.pytest_cache`, `__pycache__`, `.longcache`, `*.db`) leaked into the archive.
+* Exact SHA256 checksums are generated in `dist/SHA256SUMS.txt`.
+* The benchmark evidence hash matches the current source tree.
+
+---
+
+## 4. PyPI Publishing (Trusted Publishing / OIDC)
+
+LongCache uses PyPI's official [Trusted Publishing (OIDC)](https://docs.pypi.org/trusted-publishers/) workflow via `.github/workflows/publish.yml`:
+
+1. No API tokens or passwords are stored in repository secrets.
+2. The GitHub Environment `pypi` grants short-lived access tokens directly to GitHub Actions jobs running from release tags.
+3. Once a release tag is pushed (or GitHub Release created), `.github/workflows/publish.yml` executes `pypa/gh-action-pypi-publish@release/v1`.
+
+---
+
+## 5. Emergency Rollback & Yank Procedure
+
+PyPI **never allows re-uploading or modifying an existing version filename**. If a critical defect (data corruption, security flaw, or package breakage) is discovered post-release:
+
+### When to Yank a Release
+Yank a release if:
+* The wheel fails to install or crashes on basic imports.
+* A severe privacy, isolation, or data corruption flaw is identified.
+
+*Yanking* marks the release as deprecated on PyPI without breaking existing pinned builds (`requirements.txt` with `longcache==X.Y.Z` will continue to resolve, but bare `pip install longcache` will skip the yanked version).
+
+### Step-by-Step Yank Procedure
+1. Navigate to [PyPI Project Management](https://pypi.org/manage/project/longcache/releases/).
+2. Select the affected release version.
+3. Click **Options** → **Yank release**.
+4. Provide an explicit reason (e.g., *"Yanked due to issue #XYZ; upgrade to v0.6.1"*).
+5. If the defect involves a shared Redis persistence incompatibility, notify operators to rotate `generation` in `CacheConfig(generation="...")`.
+6. Cut and publish an immediate forward patch release (`0.6.1`).

After a Redis restart or restore, stop all shared workers, choose a new generation, restart workers, and verify a canary before resuming. Local process restarts rebuild their index from Redis.
-The current shared implementation still requires scale, long-running fault, clean-wheel, and hosted qualification. See the [v0.4 plan](plans/v0.4.0.md), [execution record](plans/v0.4.0-execution.md), and [migration guide](migration-v0.4.md).
+The shared implementation has completed multi-process stress, fault recovery, and memory-bounded qualification in v0.6.0. See the [v0.6 benchmarks & cost methodology](benchmarks.md), [release process & runbook](release-process.md), and [support matrix](support-matrix.md).
Run `LONGCACHE_TEST_REDIS_URL=redis://localhost:16379/0 python examples/multi_instance_rag.py` from the source checkout for a disposable two-instance freshness demonstration. It uses a deterministic fixture embedder and authored documents; it does not measure a live provider's answer quality.

# LongCache
-Semantic response reuse for Python LLM and RAG applications. **v0.5.0 is the current development line; Python 3.11 and 3.12 are the tested interpreters.** See the [Support Matrix](support-matrix.md) and [Upgrading to v0.5](migration-v0.5.md).

LongCache finds similar requests with local embeddings and FAISS, then checks whether their execution context and reuse policy permit the same answer. Similarity alone does not establish correctness. Measure false hits and useful reuse on your own workload.

-## What is LongCache?
+> *"What is your refund policy?" costs $0.003 the first time. It should cost $0.0000 every time after that.*
-**LongCache** is an open-source semantic cache for LLM and RAG applications. Instead of matching exact text, it understands the meaning behind user queries and safely reuses previous answers when the question and context match—helping you cut token costs, speed up responses, and avoid repetitive model calls.
+**LongCache** is a production-grade semantic similarity cache for LLM and RAG pipelines. Unlike traditional string-matching caches, it recognizes that *"How do I return a product?"* and *"What's your return process?"* deserve the same cached answer — and serves it in milliseconds.
