Phase 1, Phase 2, and Phase 3A Implementation Plan: Safety Core Stabilization, Web/Remote Hardening, and ML Training	1.1	2026-03-28	2026-03-30	Firmware BMU Team + ML Battery Health Team	In progress	refactor safety security freertos web esp32-s3 ml soh rul quantization

Introduction

This plan updates the existing BMU implementation plan by keeping Phase 1 (runtime safety) and Phase 2 (web/remote hardening) and adding Phase 3A (ML data quality, SOH retraining, RUL training, and edge quantization). The intent is deterministic execution with measurable gates and no impact on hard safety authority in firmware.

1. Requirements & Constraints

• REQ-001: Battery protection state decisions must remain 100% local on MCU and must not depend on cloud connectivity.
• REQ-002: Switching operations must use a single validated control path and preserve existing threshold protections.
• REQ-003: All I2C interactions must remain serialized with I2CLockGuard from src/I2CMutex.h.
• REQ-004: Web mutation routes must require authentication before executing switch operations.
• REQ-005: Battery index parsing for mutation routes must be strict and bounds-checked.
• REQ-006: SOH training default must use device-independent proxy mode (--soh-mode=capacity) in scripts/ml/train_fpnn.py.
• REQ-007: Quantized model output must be < 50 KB hard limit and target < 33 KB preferred edge budget.
• SEC-001: Do not introduce unauthenticated battery mutation paths.
• SEC-002: Do not relax voltage/current/reconnect/topology safety checks.
• SEC-003: Mutation endpoints must include abuse protection (rate limiting) and auditability.
• SEC-004: ML outputs remain advisory and must not replace firmware protection state machines.
• CON-001: Keep FreeRTOS task loops non-blocking; avoid long blocking calls in periodic loops.
• CON-002: Preserve compatibility with pio run -e kxkm-s3-16MB and existing kxkm-v3-16MB behavior.
• CON-003: If TensorFlow Lite backend is unavailable, ONNX Runtime quantization is mandatory fallback.
• GUD-001: Use existing DebugLogger categories for observability instead of ad-hoc serial prints.
• PAT-001: Implement changes as small, verifiable increments with build validation after each increment.

3. Alternatives

• ALT-001: Implement Phase 2 before Phase 1. Not chosen because runtime instability increases rollout risk.
• ALT-002: Introduce cloud-authorized switching gate. Not chosen because requirement mandates local-only switching authority.
• ALT-003: Add broad refactor across all modules in one change set. Not chosen to avoid high regression risk in safety-critical firmware.
• ALT-004: Keep voltage-only SOH proxy as default. Not chosen due high NaN and poor cross-device transfer.
• ALT-005: Wait for TensorFlow Lite support on Python 3.14 before quantization. Not chosen because ONNX Runtime INT8 already meets constraints.

4. Dependencies

• DEP-001: ESP32 Arduino support for task watchdog (esp_task_wdt.h) in current framework.
• DEP-002: Existing mutex infrastructure in src/I2CMutex.h must remain authoritative for Wire bus access.
• DEP-003: Existing web stack (ESPAsyncWebServer) and route wiring in src/WebServerHandler.cpp.
• DEP-004: Existing strict battery parser helper in src/BatteryRouteValidation.cpp.
• DEP-005: Existing route security helper in src/WebRouteSecurity.cpp.
• DEP-006: Python ML environment ml_venv with pandas, numpy, torch, scipy, pyarrow, onnxruntime.
• DEP-007: Existing ML scripts in scripts/ml/ (extract_features.py, adapt_features.py, train_fpnn.py, train_sambamixer.py, quantize_tflite.py).
• DEP-008: Canonical dataset artifact models/consolidated.parquet.

• TEST-004: I2C recovery threshold test: force repeated lock failures and verify recovery path triggers without deadlock.
• TEST-005: Watchdog liveness test: simulate stalled task and verify watchdog reset behavior.
• TEST-006: Rate limit test (Phase 2 pending): repeated mutation attempts beyond threshold must return HTTP 429.
• TEST-007: Audit log test (Phase 2 pending): every mutation attempt emits a structured log entry with deterministic fields.
• TEST-008: FPNN SOH quality gate: test MAPE <= 15% on device-split evaluation.

• TEST-011: SambaMixer gate: checkpoint exists and validation converges before early stop.

7. Risks & Assumptions

• RISK-001: Watchdog timeout set too low can cause false resets under transient load spikes.
• RISK-002: Aggressive I2C recovery can mask intermittent hardware faults if not paired with alerts.
• RISK-003: Rate limiting can block legitimate maintenance operations if thresholds are misconfigured.
• RISK-004: Synthetic RUL can overestimate remaining life on sparse discharge segments.
• RISK-005: Regenerated feature pass can shift distribution and require metric re-baselining.
• ASSUMPTION-001: Existing deployment keeps BMU_WEB_ADMIN_TOKEN configured where remote mutation is required.
• ASSUMPTION-002: Current hardware wiring allows safe i2cBusRecovery sequence.
• ASSUMPTION-003: Brownout implementation details may require additional board-specific validation.
• ASSUMPTION-004: ONNX Runtime remains available in ml_venv for static INT8 quantization.

• Implementation P0 realisee: script d'orchestration conteneur existant ajoute et valide localement:
  • scripts/ml/remote_kxkm_ai_pipeline.sh
  • modes ajoutes: check, bootstrap-container, run-container
• Bootstrap dans conteneur existant reussi (SYNC_OK) avec synchro du repo dans /workspace/KXKM_Batterie_Parallelator.
• Dependances ML installees dans mascarade-platformio via pip (numpy, pandas, pyarrow, onnxruntime, torch).

Evidence

• scripts/ml/remote_kxkm_ai_pipeline.sh check -> HOST OK + liste conteneurs.
• scripts/ml/remote_kxkm_ai_pipeline.sh bootstrap-container -> check deps + SYNC_OK.
• scripts/ml/remote_kxkm_ai_pipeline.sh run-container -> execution demarree puis blocage explicite:
  • BLOCKED: models/consolidated.parquet is missing in container workspace
• Verification dataset logs dans conteneur:
  • find hardware/log-sd -name "*.csv" -> CSV_COUNT=0.

Hypotheses

• Le conteneur mascarade-platformio est la cible valide pour les jobs ML batch sur kxkm-ai.
• Les donnees d'entrainement ne sont pas versionnees dans ce repo et doivent etre injectees par artefact externe.

Execution Update — 2026-03-30 (dataset unblock tooling on existing container)

• Lot prioritaire implemente pour lever le blocage dataset sans creer de nouveau conteneur.
• Script scripts/ml/remote_kxkm_ai_pipeline.sh etendu avec:
  • discover-dataset
  • inject-dataset --dataset-path <abs_path_on_kxkm-ai>
• Verification executee sur mascarade-platformio:
  • aucun consolidated.parquet trouve cote hote
  • dataset toujours absent dans /workspace/KXKM_Batterie_Parallelator/models/

Evidence

• scripts/ml/remote_kxkm_ai_pipeline.sh discover-dataset
  • CONTAINER_DATASET_MISSING:/workspace/KXKM_Batterie_Parallelator/models/consolidated.parquet
• ssh kxkm@kxkm-ai 'find /home/kxkm -type f -name "*.parquet"'
  • uniquement des fichiers de test pyarrow, aucun dataset metier consolidated.parquet
• scripts/ml/remote_kxkm_ai_pipeline.sh run-container
  • BLOCKED: models/consolidated.parquet is missing in container workspace

Hypotheses (delta)

• Le dataset metier est stocke hors /home/kxkm (volume externe, partage reseau, ou artefact CI).
• Une fois chemin fourni, l'injection dans conteneur existant est immediate via inject-dataset.

Audit Quotidien — 2026-03-30 (delta implementation start)

1. Resume journalier (5 lignes max)

• Demarrage implementation confirme sur lot P0 gouvernance + cloud/containers.
• Verification SSH/containers kxkm-ai validee, orchestration remote operationnelle.
• Blocage critique maintenu: dataset models/consolidated.parquet absent dans le conteneur cible.
• Le plan est mis a jour avec preuves runtime fraiches et actions immediates.
• Les diagrammes architecture ont ete regeneres pour enlever la corruption documentaire.

3. Blocages et dependances

• Blocage P0-Data: absence du dataset consolidated.parquet dans la cible conteneur.
• Blocage P0-CI: preuve CI distante non capturee (runs URL manquants).

4. Check de coherence

• Statuts harmonises: TODO CI passe explicitement en blocked (plus in-progress).
• TODO sans Next Action: aucun.
• Evidence UNKNOWN: retiree du delta courant, remplacee par constats verifiables.

5. Proposition de patch du fichier cible

• Patch applique: ajout de ce delta Audit Quotidien — 2026-03-30 (delta implementation start).

Execution Update — 2026-03-30 (kxkm-ai run-container unblocked, quality gate failed)

• Le pipeline distant dans mascarade-platformio execute maintenant jusqu'aux artefacts finaux sur le dataset present dans le conteneur.
• Le correctif racine a ete applique: installation du package onnx dans le conteneur puis ajout du controle onnx dans scripts/ml/remote_kxkm_ai_pipeline.sh pour eviter la regression au bootstrap.
• Le blocage restant est un gate qualite sur la quantization, pas un blocage infra ou dataset.

Evidence

• scripts/ml/remote_kxkm_ai_pipeline.sh run-container -> lecture 42,528,590 lignes, generation features_v2.parquet, features_adapted_v2.parquet, entrainement FPNN termine.
• Echec intermediaire leve: torch.onnx.OnnxExporterError: Module onnx is not installed!.

Blocker + Next Action

• Blocker: la degradation quantization depasse le seuil autorise sur le split distant courant.
• Next Action prioritaire: lancer une matrice courte d'experiences de quantization avec nouveaux paramètres explicites, puis conserver le meilleur run sous seuil.

Execution Update — 2026-03-30 (quantization iteration 1 passed)

• Premiere iteration qualite executee sur kxkm-ai avec la configuration suivante: qdq + calibration stratified + 500 echantillons + clipping 1 99.
• Cette configuration est promue comme nouveau baseline distant car elle fait repasser tous les gates.
