T-HP-035: kicad-happy Playbook Parity Report

1. BOM Analyzer Output vs Forge Review
| Dimension | BOM Analyzer (bom_analyzer.py) |
Forge Review (Codestral, 2026-03-22) |
|---|---|---|
| Input | CSV BOM (235 components, 98 unique) | KiCad .kicad_sch schematics (6 files) |
| Focus | Sourcing, LCSC matching, assembly | Design correctness, safety, best practices |
| Output type | Structured CSV + markdown report | Free-text review with severity levels |
| Automation | Fully automated, deterministic | LLM-based, non-deterministic |
| Tokens consumed | 0 (local Python) | 9,067 tokens (3,636 in / 5,431 out) |
| API cost | $0.00 | ~$0.009 (Mistral Codestral) |
| Critiques found | 0 (not in scope) | 8 critiques, 7 avertissements, 18 recos |
| Sourcing info | 8/98 LCSC matched, 70 need manual | Not in scope |
Key insight: The BOM analyzer and Forge review are complementary, not competing:
- Forge catches design issues (wrong Zener rating, redundant ESP32, I2C address conflicts)
- BOM analyzer catches manufacturing issues (unmatched LCSC parts, assembly blockers)
- A complete kicad-happy playbook needs both passes
2. LCSC Matches Found

| 10K 0603 (R4,R5) | C25804 | Basic | $0.001/pc @1k |
Coverage: 8/98 line items auto-matched (8%)
Category Breakdown
| Category | Count | Notes |
|---|---|---|
| Basic (JLCPCB) | 25 | Standard passives, common footprints |
| Extended (JLCPCB) | 3 | MB10S, 1SMA4746, BSS123 |
| Unavailable / Manual | 70 | Specialty ICs, connectors, modules |
3. Assembly Readiness Status
Status: BLOCKED
Blockers (top priority):
- 70 components without LCSC part numbers -- manual sourcing required for JLCPCB turnkey assembly
- Footprint errors detected:
- C39 (0.1uF capacitor) uses
Resistor_SMD:R_0201_0603Metric-- wrong footprint type - R10/R11 (10k resistors) use
Capacitor_SMD:C_0201_0603Metric-- wrong footprint type
- C39 (0.1uF capacitor) uses
- Custom/proprietary footprints not in JLCPCB library:
DALI:*footprints (SOP245P670X290-4N, DIOM4325X250N, SOT230P700X180-4N)tom_kicad_lib:*footprints (Jack, Audio amp)easyeda2kicad:*footprints (various)asukiaaa-kicad-footprints:*(solder jumpers)KiCad:IRF3415STRLPBF(non-standard)
Recommended path to JLCPCB assembly:
| Step | Action | Effort |
|---|---|---|
| 1 | Fix 2 footprint mismatches (C39, R10/R11) | 15 min |
| 2 | Map 25 basic passives to JLCPCB preferred LCSC parts | 1-2 hours |
| 3 | Source 15 common ICs (LDOs, op-amps, ESP32) on LCSC | 2-3 hours |
| 4 | Evaluate 55 remaining parts: consign or substitute | 4-6 hours |
| 5 | Convert custom footprints to JLCPCB-compatible | 2-4 hours |
| 6 | Re-run DRC with JLCPCB design rules | 30 min |
Estimated total effort to reach assembly-ready: 10-16 hours
4. Playbook Parity Assessment
What kicad-happy playbook covers vs what was executed:
| Playbook Step | kicad-happy Reference | Hypnoled Execution | Parity |
|---|---|---|---|
| Schema review | Forge prompts per sub-schematic | 6/6 sub-schematics reviewed | FULL |
| DRC check | KiCad DRC + custom rules | Not run (no .kicad_pcb in checkout) | MISSING |
| BOM extraction | kicad-cli or s-expression parser | extract_hypnoled_datasets.py + bom_analyzer.py |
FULL |
| BOM normalization | Deduplicate, normalize values | 98 unique from 235 total | FULL |
| LCSC sourcing | Auto-match + manual fallback | 8/98 auto, 70 need manual | PARTIAL |
| JLCPCB export | Comment/Designator/Footprint/LCSC/Qty CSV | Generated: hypnoled_jlcpcb_bom_2026-03-25.csv |
FULL |
| Assembly gate | All parts sourced + footprints valid | BLOCKED: 70 unmatched + 2 footprint errors | BLOCKED |
| Review report | PDF + markdown with findings | forge_review_DALI_PCB_2026-03-22.md + this report |
FULL |
Parity Score: 5/8 steps complete, 1 partial, 2 blocked
To reach full parity:
- Run KiCad DRC on
.kicad_pcb(requires board file in checkout) - Complete LCSC sourcing for remaining 70 components
- Fix footprint errors and re-export
5. Conclusion
The kicad-happy playbook has been replayed on Hypnoled with the following results:
- BOM analysis pipeline (parse -> normalize -> suggest -> report) works end-to-end
- JLCPCB BOM export generated in correct format (5-column CSV)
- Forge review and BOM analyzer outputs are complementary and both needed
- Assembly status is BLOCKED until manual LCSC sourcing is completed for 70 parts
- Two footprint errors found that would cause assembly issues (C39, R10/R11)
- The
bom_analyzer.pytool proves its value as a pre-fabrication gate check
