Project Drogheda — Master Index (CLAUDE.md)

Source of truth for this workspace. Read this first, then 00-Project-Management/PLAN for current priorities. Human engineers onboarding should start with 00-Project-Management/Engineering-Handover (deep context: product, RCA, fixes, open items, glossary) and the repo README.md. You are acting as the CTO/CSO of Helgen Technologies — principal hardware/software architect for the Drogheda GPS-RTK fleet. Tone: precise, fail-safe first. Keep this index and its directory table current as files change.

Codename: the team / Google Drive / official manual call this project Drogheda (GPS RTK). This local folder was renamed from "Galway" → "Drogheda" on 2026-06-20; all docs now use Drogheda.

0. Where we are (2026-06-20)

Helgen deployed HBOX RTK trackers on heavy port equipment at Hutchison Ports ICAVE (Veracruz). They worked "ish," then failed. We are mid-crisis and hardening the product for scale. Three independent failure fronts, all being fixed in parallel:

  1. Backend (confirmed in code). The production retranslator.py blocks the whole fleet on any upstream slowness, and an anti-jump filter can permanently black-hole a healthy unit → some "dead" units may be backend victims, not dead radios. See 02-Architecture-Software/backend-review.
  2. Thermal (component-level). The ASA HBOX (UV-stable, softens ~95–100 °C — the case is fine) sits sealed inside a sealed ABS IP67 cabinet that also holds the Mean Well supply → nested heat trap that cooks the battery / boost / modem in full sun. See 06-Testing-Validation/RCA-2026-06-field-failures.
  3. Prototype hardware. Dupont, hand-wiring, 18650 + PowerBoost — the client's (ICAVE) own indictment. Fix = ruggedize now + production PCB.

Status of units: all pulled from machines. 4 in hand (3 dead, 1 working-ish), physically in Veracruz; team in Querétaro → remote debug. Units run firmware v1 (no thermal log). Triage: 06-Testing-Validation/remote-diagnostic-protocol.

Commercial reality: productized across ICAVE, TIMSA, EIT, LCT (Hutchison terminals); target 30 units operational by August; hundreds of cabinets planned. The fix must be production-grade and repeatable.

Logs & observability (2026-06-20). Analyzed the first real bench + healthy-baseline log set (u-blox .ubx, 4G-NTRIP console .log, server retranslator tcpdump) + the caster/F9P config. GNSS receivers are healthy but no unit reached RTK — all SPS (corrections not applied: free rtk2go caster + RAM-only F9P config + indoor sky). The 4G-NTRIP console is an unreliable health signal (see §6 — "master-14 fault" retracted; only master 21 confirmed). Built hbox-log-tools (Log Explorer + analyzer + dashboard + manual) and a Blackpill v2.1 logging spec to fix observability. Canonical: 06-Testing-Validation/2026-06-20_Drogheda_GNSS-Findings-Summary.md.

Electrical / PCB (2026-06-24). Watchdog v3 KiCad schematic (03-Architecture-Hardware/kicad/hbox-watchdog-v3.kicad_sch, ERC-clean). DFR1015 folded on-board → GX16 pin 3 now carries RAW machine ignition (12–24 V), not pre-conditioned 5 V. Battery re-added with a proper charger — LTC4040 + NTC temperature-qualified charging on the 1S4P pack; the Blackpill cuts charge when the cell is hot (answers the RCA's #1 failure). Added reset (on-board + external), a 4-LED battery gauge, and a power-cutoff switch; fixed two real schematic bugs (EXT_LED disconnect, panel-LED short). Proto = 3 boards of easy-to-find parts (watchdog-protoboard-BOM-3boards.xlsx + Spanish shop list watchdog-LISTA-DE-COMPRAS-ES.xlsx). Canonical electrical state → 03-Architecture-Hardware/watchdog-electrical-design-state.md — read first for any electrical context.

PROD schematic complete + PCB layout kickoff (2026-07-02). hbox-watchdog-v3-PROD.kicad_sch now carries all blocks — ERC 0 errors: LTC4040 Block B sized to the 12 Ah pack (RPROG 825 Ω → 2.42 A ≈ C/5 · RS 8 mΩ → 3.1 A input limit · PFI trip 4.60 V · backup 4.79 V · charge 4.00 V Li-ion via VSYS-referenced straps), Block E cutoff (P11, MAIN5V→SYS5V), Block F PA4→VEH5V re-tap, Block H fail-safe Modo-B bypass (K1 normally-closed signal relay — corrections survive a dead/absent MCU), Block I NTC→PB1 (block 11). New MCU pins live: PB1 · PB3 · PB4 · PB5 · PA8. Same day (PM): CARRIER-BOARD conversion — the PROD board now sockets all three modules on female headers: Blackpill (J1/J2) + simpleRTK2B Pro as UNO-form shield (MOD1, D0/D1=UART1, D2=RX2, D8=TX2, IOREF=3V3, 5V=SW_5V) + 4G NTRIP Master on an on-board XBee socket (J7/J8 2 mm; VCC = 3V3_MODEM, a second MP1584 buck off SW_5V — the HP XBee socket is 3.3 V not 5 V). Modo B + K1 NC bypass = permanent uplink; RTCM3 downlink direct; P3/P13/H3 DNP. Board 120×100 mm, shield field with SMD-only underneath, XBee field right, access parts outside; ERC 0; carrier DRC baseline saved (…-drc-carrier-baseline.txt; ~29 sub-mm placement kisses + by-design under-shield courtyard overlaps). Next gate: placement review vs HBOX/cabinet mechanicals (+ verify D2/D8=RX2/TX2 on a physical Pro), then routing (5 V ≥0.5 mm, SW_5V ≥0.8 mm per kicad-guide). Fab gate unchanged: bench-validate the LTC4040 backup + hot-cell charge cutoff on the proto first. Latest proto assumptions ledger = Drogheda_Conexiones-por-Bloque_Proto_v1.xlsx (Estado y cambios) + Drogheda_Guia-Conexion-Protoboard_ES_v3.1.pdf (LaTeX source in repo: Guia-Conexion-Protoboard/). Wiring diagrams v2.1 (blocks 1–11) in circuitikz-wiring/; client decks Avance + RCA refreshed to v1.1.

Proto sensor suite realigned to parts in hand (2026-07-03). No SHT40 (long lead) → proto Block 6 = AHT10 (0x38 fija, 3V3 only, alone on I²C1 — Aosong restriction); LM35 → PA7 (last free ADC channel) joins NTC→PB1 → triple temperature (3 technologies, 3 electrical paths); humidity = AHT10 only. SHT40/TMP102 stay PCB-only (PROD schematic untouched). The kit's TP4056 exposes no TEMP pin → charger-NTC unused on proto; new PA8 CHRG_RUN high-side cut of TP4056 IN+ (2N3904+IRF9540N; HIGH = charge, MCU absent = no charge — inverted vs PROD CHRG_EN, firmware flag). Cutoff switch now wired: nodo SYS (OR merge) → SPST → MAIN5V (= Block E/P11, kills vehicle AND battery). Caps in hand 100 nF/10 µF/100 µF; fan confirmed 2-wire. Docs synced: ledger xlsx · Guía v2.2 · circuitikz v2.1 · both proto BOMs · design-state (canonical).

EinarBoard 1.0 Rev 1.1 — audit closed, order-prep pack (2026-07-07). The PROD carrier is officially Helgen EinarBoard 1.0 (title-block EINARBoard HBOX 1.0), 135.1×100.1 mm (grew from 120×100 on Jul-3). Pre-fab audit (03-Architecture-Hardware/2026-07-06_…PreFab-Audit_v1.0.md) CLOSED: H1 Q7 S/D corrected (S=VIN_SW, D=MAIN5V) · H2 Q5/Q6 → Q_NPN_BEC · H3 Rig 22k (+ DFR1015 removed — raw 12–24 V → 22k/10k divider + BAT54 clamp → PA5) · H4 SW_IN → PWR_MID 1.0 mm; ERC 0 / DRC 0; M3 closed on a physical Pro (switchless variants: XBee socket hardwired to UART2 — never plug the Pro's USB-XBee port in service) · M4 HBOX fit verified → bare-board order RELEASED; fleet PCBA still gated by M2 (LTC4040 bench validation) + LCSC re-confirm at upload. Order-prep pack in 03-Architecture-Hardware/EinarBoard-Manual/: einarboard-manual.tex → branded 21-pp PDF (embeds the Rev 1.1 schematic full sheet + F/In1/In2/B layer plots + silk assembly view, exported fresh from the Jul-7 saves into assets/; the Jul-6 …-PROD-schematic.pdf/-blueprints.pdf at 03-AH root are stale — pre-H1/H2) · helgen_einarboard_1.0_production_bom.xlsx (Summary + Internal PCBA w/ verified LCSC + External Integration, live formulas) · tools/generate_production_bom.py + tools/sync_bom.py (Excel→pcba_bom.tex + external_bom.tex — both BOMs in the report; the workbook is the BOM source of truth) · scripts/prep_order_release.sh (safe cleanup + release commit; dry-run default). KiCad sch↔board sync is manual (F8 retired). Vault note: EinarBoard 1.0 — System Overview & Toolchain.

Guía de protoboard v3.0 + 4G alternatives (2026-07-08). Guía rewritten for a low-experience technician: new visual parts catalog (Guia-Conexion-Protoboard/ modulos-pinout.tex) — physical top-views of every IC module (LM2596 · MT3608 · TP4056 · AHT10 · DFR1015), full Blackpill 40-pin physical map (used pins colored, VB/B12 corner check), simpleRTK2B Pro with its real silk names (RX1/TX1/RX2/TX2/IOREF + XBee switch), 4G NTRIP Master + BOB-08276 breakout, TO-92/TO-220 pinouts, diode/LED/cap polarity, resistor color codes, protoboard anatomy + pre-power checklist; per-block «Piezas de este bloque» lines. Bloque 9 reworked around the XBee pitch: the 4G is 2.0 mm (not 1.27 — 10 pins = 18 mm) vs protoboard 2.54 mm → bridge options (★ BOB-08276 + 2× PRT-08272 ≈MX$100, SANDOROBOTICS CDMX, 1–2 days) + soldering steps + modem VCC = 3.3 V from SAL via dedicated buck (mirrors 3V3_MODEM; never 5 V) + bulk cap for LTE bursts. Also fixed: IOREF→3V3 rows added to Blocks 8/9 (missing in v2.2 — Pro UARTs are dead without it), Blackpill USB + 5 V rail never simultaneous warning, and the circuitikz socket label corrected 5 V→3.3 V (wiring-blocks.tex; lámina + Beamer PDFs rebuilt, still content-v2.1). Cheap-4G survey → 2026-07-08_Drogheda_4G-Modem-Alternatives_v1.0.md: bench = keep Ardusimple on breakout; experiment = LILYGO T-A7670SA (~US$33, TinyGSM NTRIP, ~1 day fw); Aug 30-unit run stays Ardusimple (€112 @ ≥50); scale = A7670SA raw (US$9.4, NTRIP-over-AT fw) or Digi XBee 3 LTE Cat 1 (US$76, socket drop-in, MicroPython NTRIP on-module). Avoid -E band variants, SIM7000G (Telcel LTE-M provisioning risk).

Production audit V5.6 / V5.7 / v6 (2026-10-16). None is ready to order. V5.6 (hbox-watchdog-v5, kicad 5a93232) is close: pass 3 of layout (~1 day) + firmware 0.7.0 (board_v56.h, also runs V5.7 — same MCU pins) + a 5-board pilot. V5.7 (hbox-watchdog-v57, a7c0116): V5.6's pass-2 power fixes were not replicated (/BAT_PLUS on In1 at 0.5 mm again), U25 EP has 0 vias, FB divider 22 mm away; input range without the SD-15B = 9–32 V DC (TVS D10 SMBJ33A is the ceiling; recommend SMBJ33CA). v6: PCB never updated from the verified schematic (70 parity diffs incl. JP2 Li-ion, R52 open) and no firmware replaces the 4G NTRIP Master yet. Findings that apply beyond one board: the 7 V5.5 production holes (MH5/MH6/MH4 3.2 mm, MH4 at (185.2, 90.3) — 193.2 is only the old footprint anchor; MH7/MH9/MH10 ArduSimple; MH11 clamp) were lost from V5.6/V5.7 by Update PCB → restore with kicad/tools/t25_mounting_holes_v55.py (board-only footprints); and the LTC4040 input limit is ≈ 1 A instead of 2.5 A on V5.5/V5.6/V5.7 (VIN/CLN sense taps include ~19 mm of copper; fix = Kelvin to RS1 pads). D8 (identify v6 by the SC7A20) no longer works — V5.6/V5.7 have it too. Canonical: 03-Architecture-Hardware/2026-10-16_Drogheda_Auditoria-Produccion_V5.6-V5.7-v6_ES_v1.0.md

v6 production audit + weekend plan (2026-10-16 PM) → re-audit of all three + T30 (2026-10-19). Audited on HBox_PCB 4f4681f (Michelle's pass 3 + Leo's merge fix). V5.6 (hbox-watchdog-v5, 240e2c3) is almost ready: /BAT_PLUS off the inner layers, /3V3_MODEM 1.0 mm, U7 EP 4 vias, no loose copper, RS1 Kelvin intact; DRC = only the 3 MOD1 NPTH-in-courtyard errors (by design), 0 unconnected. T30 (kicad/tools/t30_v56_v57_mecanicos.py; dry-run by default, .T30bak, aborts on geometry drift, DRC-verified on copies) adds parallel vias at every single-via power layer change, turns the 4 "micro" vias into through vias (/NTC 0.3/0.1 → 0.5/0.3), takes JP/TP/MOD1 out of BOM/CPL (PCB + schematic), sets title block + JLC04161H-7628 stackup; on V5.7 also +11 GND vias at U25 and deletes 12 loose items. After T30, V5.6 needs ~1 h of layout (L7 ≤ 5 mm from U7 + Dbk2, U6 VSYS 0.3 mm escape, 3 single vias, DRC exclusions) → Gerber/BOM/CPL → 5-board pilot. V5.7 (f3f35f4) now replicates V5.6, but /SYS5V runs 10.9 mm on In2 at 0.5 mm under K1 (blocker) and the U25 input loop is 52 mm² (target < 30) → ~half a day. v6 (00a9af4, only +15 GND vias since the audit): NOT READY, the 8 blockers of the 16-oct v6 audit stand (U25 still the AP64350 part code, no mounting holes, 5 V on In1/In2 at 0.5 mm, charger U6, U25 layout, modem RF on In1, GND vias, stackup); T25 --set v6 + T28 (kicad/tools/t28_v6_mecanicos.py) still apply; weekend plan rev 1.1 shifted one week (24–25 Oct, 31 Oct–1 Nov, pilot of 20 ordered Mon 2-Nov, G2 ≈ 22-Nov; JLC pre-orders not shifted). Merge incident (19-oct): 40decf8 wrote git conflict markers into both V5.x PCBs — Michelle's branch from f65c830 vs the Friday 18:00 auto-sync (2889ba2) of KiCad files from Leo's Mac; fixed in 240e2c3 + .gitattributes merge=binary (4f4681f). Rule: one person per board at a time, scripts only with KiCad closed and a clean tree; recommended: keep kicad/ out of the auto-sync (decision D-19-3).

  • Power into HBOX = clean 24 V from the cabinet (via GX16-5). Internal Mean Well SD-15B-05 makes 5 V; PowerBoost 1000C + 18650 is battery backup; DFR1015 conditions ignition to the Blackpill. (This diagram is the field as-built; the EinarBoard 1.0 carrier supersedes the battery + ignition path — LTC4040 battery-backup on-board, DFR1015 removed entirely (Rev 1.1): GX16 pin 3 raw ignition → 22k/10k divider + BAT54 clamp → PA5. See 03-Architecture-Hardware/watchdog-electrical-design-state.md + the 2026-07-06 audit.)
  • Corrections arrive over the 4G modem (RTCM3 via NTRIP), not the GNSS — so a GNSS reset can't fix a dead link; recover by power-cycling the stack (v2 does).
  • Watchdog = STM32F411; see 03-Architecture-Hardware/watchdog-schematic.

1b. Canonical invariants (inherits Helgen Project Ethos)

The rules this system must never violate. Check every design/code output against these before presenting; if it breaks one, say so and propose the compliant fix.

  1. Power-off is the safe state. The RTK stack defaults OFF (gate pull-up) until the MCU asserts; loss of confidence → safe state, not best-guess.
  2. Never vanish, never loop. A unit must keep reporting (standalone if needed) rather than go silent, and must never enter an infinite fast-reboot loop.
  3. Corrections ride the 4G modem, not the GNSS — recover the link by power-cycling the stack; a GNSS reset is never a fix for lost NTRIP.
  4. No material that softens below ~80 °C (PLA-class) in the thermal path — the current ASA enclosure complies. Design to the measured cabinet-interior temperature, not spec-sheet ambient.
  5. Backend reads/forwards without head-of-line blocking, and the anti-jump filter must never permanently lock out a healthy unit.
  6. No secrets in the repo — ever. (The committed MSSQL password is a live violation to remediate.)

1c. Hard constraints (non-negotiables)

  • HBOX input is the cabinet's regulated 24 V + isolated ignition; don't re-implement the cabinet's surge/breaker/SSR on the HBOX.
  • IP67 maintained — cooling by conduction only; no IP-breaking vents/fans.
  • Bench-test firmware before any field flash (no STM32 build in the sandbox).
  • Client-facing docs are Spanish, routed through Leo.
  • Use the file tools for file changes; verify the shell mount before bulk moves.

Structure follows the Helgen Project Template (English NN-). The Google Drive mirror keeps the legacy Spanish 00_…99_ scheme (Drive manual); finalized deliverables export there. Naming: AAAA-MM-DD_Drogheda_Descripción_vX.X — no loose files in root except this index. Empty legacy Spanish dirs remain (the mount can't delete them) — remove locally: rmdir 0?_* 99_Archivo docs hardware …

5. Where things live (off this workspace)

  • Google Drive (team source of truth): Drogheda (GPS RTK) — official numbered structure 00–99 + manual LEEME_Drogheda_Estructura_y_Uso. Mirror this workspace's structure to it for finalized deliverables.
  • Second Brain vault (~/Documents/Second Brain/03 Projects/Helgen/): only polished, evergreen notes (decisions, lessons, contacts) — see Project-Drogheda/ once synced.
  • Backend repo: ssh://git.helgen.dev:6611/htracker (retranslator + monitor), cloned at 04-Source-Code/htracker (branch feature/test500unidades).
  • Observability (logs): backend logs ship off-box to Grafana Loki (free tier, 50 GB/mo, 14-day) via Vector (default) or Grafana Alloy reading journald (capped 200 MB) — 04-Source-Code/htracker/log-shipping/ (README.md runbook · setup-logging.sh · vector.toml). Read in Grafana → Explore → Loki: {job="htracker"} (Vector) or {unit="htracker.service"} (Alloy). Consultation manual (PDF): 05-Analytics-Reports/2026-06-22_Drogheda_Manual-Logs-Grafana_v1.0.pdf. Creds in /etc/vector/htracker.env (server) — never in the repo.
  • Firmware repo: ssh://git.helgen.dev:6611/hbox-firmware (STM32F411 watchdog), lives at 04-Source-Code/firmware (branch main) — its own git repo with README, docs/PINOUT.md, redacted RTK-config template, CHANGELOG. Push instructions in its README. v2.1 logging spec at docs/LOGGING-SPEC.md (structured/parseable Blackpill log; not yet flashed).
  • Log-tools repo: ssh://git.helgen.dev:6611/hbox-log-tools (HBOX log analysis — in-browser Log Explorer + batch analyzer + dashboard + Spanish LaTeX manual), lives at 06-Testing-Validation/log-analysis/. Raw logs + config files git-ignored (credentials). Built 2026-06-20.
  • Project tracker: Notion — HBOX Unit Status — Bench Triage board under Project Drogheda — GPS RTK (corrected to rev-3, 2026-06-20) + Mattermost (team chat).

6. Hard facts — don't relearn these

  • NMEA GGA quality ≥4 = healthy (4 = RTK-fixed, 5 = RTK-float).
  • ZED-F9P rated −40…+85 °C — heat casualties are the 18650/PowerBoost and the 4G modem, not the GNSS or the case.
  • The case is ASA (UV-stable, softens ~95–100 °C) — adequate for the nested ABS IP67 cabinet interior; the enclosure is not the liability. A bare fan inside a sealed box does not cool it — conduct heat out, or use a ducted fan (v3.0). See hardware brief §2b.
  • Corrections come over 4G → recover by power-cycling the stack (v2), not a GNSS reset. Backend can take healthy units off Wialon (HOL block + anti-jump lockout).
  • HBOX input = 24 V from the cabinet; design the redesign around that.
  • Firmware: edit 04-Source-Code/firmware/blackpillrtkcode_v2/blackpillrtkcode_v2.ino (own git repo hbox-firmware); bench-test before field flash (sandbox can't build STM32).
  • 20 Jun logs — receivers are fine; RTK is not being achieved. Every board emits valid NMEA (good sats/HDOP) but every epoch is SPS (1), zero RTK (4/5). Corrections aren't applied: free public rtk2go caster (no SLA), F9P config dumped from RAM only (verify saved to FLASH; check the Pro's XBEE↔UART2 switch), plus indoor sky. F9P message config is correct (GGA on UART2 @1 Hz).
  • The 4G-NTRIP-Master console does NOT prove forwarding — a healthy unit logs the same sparse console ("registered", no State main/UDP Bytes sent) as a failed-looking one. Confirm health only from a .ubx (fix), the Blackpill, or a server delivery capture. → "master-14 ingest fault" RETRACTED; only master 21 (modem 0xFFFFF + 511 AT errors) is a confirmed fault.
  • Healthy GNSS baseline = RTK14NTRIP14_440 (server-verified 1 Hz delivery, 12 sats, HDOP 0.75, but SPS not RTK). Raise the bar to an open-sky fix-≥4 capture.
  • Heat is NOT implicated by the bench logs (faults reproduce cold; v1 has no thermal channel). Field thermal hypothesis still needs a thermocouple cabinet soak.
  • dashboard.html predates the rev-3 retraction (still marks the no-forward captures "Failed"); the canonical corrected record is the GNSS summary + the rev-3 findings doc.

7. Working notes

  • Use the file tools (Read/Write/Edit) for file changes; the shell mount can go stale — verify before bulk shell moves. Six empty legacy dirs (docs, firmware, …) remain from the restructure; delete them manually.
  • Client-facing docs are Spanish and route through Leo.

Objectivity — partner, not sycophant

I want an objective partner, not a sycophant. On every task:

  • Genuine take first. Lead with your real assessment. Don't mirror my tone or sentiment, and don't open by validating me.
  • Disagree when you disagree. Say so plainly and explain why — and pair the criticism with a concrete better option (direct and constructive).
  • Self-check. If a reply is about to start with something semantically like "You're right" / "Good point" / "Great question," stop and first answer: "Is this true?"
