+## Implementation Update - 2026-05-18
+
+The retrieval, activation quality, and evaluation slice is complete.
+
+Implemented outputs:
+
+- `phase_memory.retrieval` adds deterministic graph-neighborhood retrieval,
+  candidate scoring, event-path selection, pluggable token estimator protocol,
+  neighborhood activation planning, and activation quality reports.
+- Retrieval supports max hops, edge-kind filters, direction filters, phase
+  filters, and memory kind filters.
+- Event-path activation selects bounded event windows from structured
+  `MemoryPath` records and treats inactive paths as opt-in.
+- Ranking signals include explicit priority, graph distance, phase, lifecycle
+  state, confidence, source-backed status, freshness, and policy allowance.
+- `WordCountTokenEstimator` provides deterministic local budget accounting.
+- `activation_quality_report` emits selected expected nodes, omitted required
+  nodes, policy-denied required nodes, token budget utilization, stale item
+  count, provenance coverage, source span coverage, and explanation coverage.
+- `docs/activation-quality.md` documents retrieval, event paths, scoring,
+  estimator boundaries, and evaluation metrics.
+
+Validation:
+
+- `python3 -m pytest` -> 46 passed.
