+# Next Wave Implementation Plan — 2026-08-26
+
+## Context
+Wave 5 gap closure complete (81/81 checkboxes [x] in MODULE_GAP_ANALYSIS_WAVE2.md).
+This plan targets Wave A closure + Wave B deferred production code gaps.
+
+## Priority Ranking (P1 = highest business risk)
+
+| ID | Module | Gap | Type | Priority |
+|---|---|---|---|---|
+| N1 | voice | Wake-word/intent/command pipeline fallback alignment; partial backend failure matrix; noisy wake-word adversarial expansion | Wave A | P1 |
+| N2 | analytics | Federated query coordinator real wiring + forecasting model integrity check | Wave A/B | P2 |
+| N3 | llm | Thread-safety audit — top-20 shared state sites (static caches, global registries) + `std::atomic`/mutex additions | Wave B | P3 |
+| N4 | llm_wiki | RocksDB backend replacing in-memory mock (Wave B partial closure) | Wave B | P4 |
+
+## Subagent Assignment
+- **impl-voice-wave-a**: N1 (Voice A3 hardening)
+- **impl-analytics-wave**: N2 (Analytics federated coordinator + forecasting)
+- **impl-llm-threadsafety**: N3 (LLM thread-safety top-20)
+- **impl-llm-wiki-rocksdb**: N4 (LLM Wiki RocksDB backend)
+
+## Acceptance Criteria per Gap
+### N1 Voice
+- Wake-word/intent/command pipelines: each path has explicit fallback that returns a safe-default response + logs THEMIS_WARN
+- Partial backend failure: if primary backend throws/times out, secondary path is tried before returning fail-closed error
+- Noisy wake-word: test coverage for wake-word detection under noise (false-positive + true-positive cases)
+- Tests: `tests/voice/test_wave_next_voice_hardening.cpp` (10+ tests)
+- ROADMAP: `[ ]` items flipped to `[x]`
+
+### N2 Analytics
+- Federated coordinator: `distributed_analytics.cpp` executeDistributed() wires real cross-shard retry (not just caller-re-issue)
+- Forecasting: model integrity check (checksum/version validation before serving)
+- Tests: `tests/analytics/test_wave_next_analytics_hardening.cpp` (8+ tests)
+
+### N3 LLM Thread-safety
+- Top-20 sites: `std::atomic<>` wrapping for shared counters; `std::mutex`+`std::lock_guard` for shared maps/caches
+- No data races on repeated concurrent `getAdapter()`, `getModel()`, `getCache()` calls
+- Tests: thread-safety stress tests (2+ threads, 100+ iterations)
+
+### N4 LLM Wiki RocksDB
+- `LLMWikiPluginImpl` persistence backed by RocksDB column family (not in-memory hash map)
+- Index/query/cache operations use `db->Put()`, `db->Get()`, `db->NewIterator()`
+- STUB/SIMULATION NOTE updated: Removal Plan changed from "pending" to "done"
+- Tests: verify persistence survives restart (write → close → reopen → read)
+
+## Target Branch: develop (current: copilot/core-modules-gaps-analysis)
