+# Atomic Memory extraction evaluation
+
+This focused evaluation checks that Atomic Memory extraction retains durable facts while refusing to turn historical
+instructions and task-specific procedures into commands for a future Agent. Its synthetic UTF-8 fixture contains no
+private user content and covers both built-in extraction profiles in English and Chinese.
+
+The three dispositions belong only to this evaluation:
+
+- `atomic_memory`: at least one subject-bound declarative candidate is required;
+- `experience_or_skill`: the evidence is procedural and must produce no Atomic Memory candidate;
+- `reject`: the evidence has no durable memory content and must produce no candidate.
+
+No disposition or routing field is added to the production `AtomicMemoryCandidate` schema.
+
+## Offline validation and tests
+
+From the repository root:
+
+```bash
+uv run python -m evaluation.memory.atomic_extraction validate
+uv run pytest evaluation/memory/atomic_extraction/tests
+```
+
+The deterministic tests validate manifest coverage, case-declared expected literals and evidence IDs, independent
+factual-retention and instruction-leakage scoring, content-free reports, CLI behavior, and the all-empty failure
+control. Only expected literals declared by a case are exempted from instruction-leakage scanning. The tests make no
+provider calls.
+
+The deterministic leakage heuristic is safety-first for ambiguous sentence-initial Chinese verb-object phrases such
+as `设置值` or `配置文件名`: they are treated as imperative. Declarative candidates should retain an explicit subject or
+state, for example `项目的配置文件名已记录`.
+
+## Opt-in live run
+
+Configure an existing PowerContext Server environment file with a real generation provider. Then run:
+
+```bash
+uv run python -m evaluation.memory.atomic_extraction run \
+  --env-file /absolute/path/to/provider.env \
+  --run-id atomic-extraction-YYYYMMDD \
+  --output-directory evaluation/memory/atomic_extraction/results/atomic-extraction-YYYYMMDD
+```
+
+The runner records the exact built-in Prompt versions, instruction SHA-256 values, compiled digests, dataset manifest
+SHA-256, provider/model identity, safe model settings, timeout, request limit, candidate kind/text/evidence IDs, and
+portable usage. Provider credentials and raw provider responses are never recorded.
+
+`results/` is ignored because `observations.private.jsonl` contains generated candidate text. `report.json` and
+`report.md` contain aggregate counts only. A provider failure is `incomplete`, not an instruction-safety pass.
+
+Rebuild a report without making provider calls:
+
+```bash
+uv run python -m evaluation.memory.atomic_extraction replay \
+  --run-directory evaluation/memory/atomic_extraction/results/atomic-extraction-YYYYMMDD
+```
+
+After reviewing a passing run, regenerate and pin only its content-free evidence for a PR:
+
+```bash
+uv run python -m evaluation.memory.atomic_extraction pin \
+  --run-directory evaluation/memory/atomic_extraction/results/atomic-extraction-YYYYMMDD \
+  --destination evaluation/memory/atomic_extraction/reports/atomic-extraction-YYYYMMDD
+```
+
+The `pin` command validates the strict run manifest, re-scores the private observations, requires a complete passing
+run, and regenerates the public report rather than copying it. The PR description should link the pinned directory and
+summarize the provider/model/settings and two quality gates. Do not copy or commit `observations.private.jsonl`.
