+> **F8 is permanently retired on this board** — sync is manual (see memory/process note). Bare-board
+> order RELEASED conditional on the two physical gates (M3: D0/D1 on a physical Pro; M4: HBOX fit).
+> PCBA still blocked by M1 (LCSC coverage 18/77 lines).
+>
+> **M3 CLOSED (2026-07-07):** verified on a physical simpleRTK2B Pro — silk reads D0=TX1, D1=RX1,
+> D2=RX2 (shared XBee-TX), D3–D7 empty, D8=TX2 (shared XBee-RX). Carrier mapping confirmed
+> position-for-position.
+>
+> **H5 — NEW HIGH (2026-07-07, caught by the M4 gate / CAD engineer): Blackpill socket rows one
+> grid step too wide.** Board J1↔J2 = 17.78 mm (0.7"); the physical WeAct Blackpill measures
+> **15.24 mm (600 mil)** row-to-row (calipers: 15.87 outer − 0.64 pin = 15.23 c-c; corroborated by
+> the KiCad forum footprint thread — "standard DIP", 600 mil — and a pixel re-measure of the WeAct
+> dimensions drawing: rows ≈15.5 mm, insets ≈2.7 mm on the 20.78 board). **Order RETRACTED until
+> fixed.** Fix: move **J2** from y=74.1031 → **y=71.5631** (Δ−2.54; the landing strip is
+> footprint- and via-free; moving J1 instead would collide with Q1/Q5), re-drag the 20 stubs,
+> refill, DRC 0, re-export, **then 1:1 paper test with the real module before ordering** (and same
+> paper test for MOD1 + J7/J8 + the physical modem while at it). Pin functions are unaffected —
+> layout-only fix; schematic untouched.
+>
+> **H6 — NEW HIGH (2026-07-07, surfaced by Leo's "silk on the back" question): MOD1 footprint is
+> FLIPPED to B.Cu** — has been since the Jul-3/4 re-placement (preCarrier backup shows F.Cu; preusb
+> onward B.Cu). The UNO socket pattern is x-mirrored: a shield plugged from the top cannot mate.
+> The back-side silkscreen was the symptom, not the problem. Only MOD1 is flipped (full 132-footprint
+> side sweep clean). Fix: select MOD1 → **F** (flip to F.Cu — silk returns to front automatically) →
+> reposition the envelope back over the shield field (check P3-notch + J8 clearance per the Jul-2
+> review notes) → reroute the 6 attached pads (2=3V3, 5=SW_5V @1.0 mm, 15/16=GNSS_RX/TX,
+> 17=DOUT_4G, 23=USART1_RX) → refill → DRC → re-STEP for the CAD engineer. Audit lesson recorded:
+> **footprint SIDE is now a standing checklist item; the 1:1 paper test with real modules is
+> mandatory before any socketed-carrier order.**
+>
+> **H6 RESOLVED 2026-07-07 — NOT A DEFECT (auditor false alarm). DO NOT FLIP MOD1.** The pad
+> pattern was physically validated by Leo: 1:1 print + the real simpleRTK2B Pro in the intended
+> orientation (antenna top-left, USB-C pair at bottom), including the discriminating count check —
+> 18-pin digital edge on the 18-hole row (y≈81) with the 10-pin subgroup at the correct (right)
+> end, 14-pin edge on the 14-hole row. Pads are correct as-placed; the B.Cu hosting is a
+> modeling/visual quirk only (outline on B.Fab, 3D model rendered underneath). Action taken:
+> move MOD1's B.Fab/B.CrtYd (and any B.Silk) graphics to the front layers — pads untouched.
+> **Auditor lesson:** the hand-derived back-side mirror transform produced a false positive;
+> for back-footprint geometry trust KiCad-computed outputs (IPC-D-356, gerbers, 3D/STEP) and the
+> physical 1:1 test — never a manually reconstructed flip. **Pro revisions differ:** older Pros have an "XBEE TO GPS UART" switch —
+> park it on UART1; newer Pros (like the verified sample) have NO switch — the XBee socket is
+> hardwired to UART2 (silk: "XBEE-TX/GPS RX2", "XBEE-RX/GPS TX2" on the rail pins). Assembly
+> checklist, both revisions: Pro's XBee socket stays EMPTY; if a switch exists → UART1; **never
+> plug the Pro's "USB XBee" port while the unit is in service** (its FTDI sits across UART2 on the

+\section{System overview}
+\textbf{EinarBoard 1.0} (title-block \emph{EINARBoard HBOX 1.0}; KiCad lineage \texttt{hbox-watchdog-v3-PROD}) is the HBOX carrier/motherboard for the Drogheda GPS-RTK fleet tracker deployed on heavy port equipment. It hosts the full electronics stack of an HBOX unit on plug-in sockets and carries the watchdog, power, backup-battery, thermal-sensing, and fail-safe corrections infrastructure on its own copper:
+
+\begin{itemize}
+\item \textbf{STM32F411 Blackpill} (watchdog MCU) on J1/J2 $1{\times}20$ sockets --- supervises the stack, power-cycles it on lost corrections, gauges the battery, qualifies charging by temperature, and injects \texttt{\$PHLG} diagnostics on the Modo-B uplink.
+\item \textbf{simpleRTK2B Pro} (u-blox ZED-F9P) as an Arduino-UNO-form shield on MOD1 --- GNSS RTK engine.
+\item \textbf{4G NTRIP Master} (XBee-form LTE) on J7/J8 2.00\,mm sockets at \net{3V3\_MODEM} --- corrections downlink and NMEA uplink. USB-C service port J9 firmware-updates the modem in place.
+\item \textbf{LTC4040} battery-backup manager with a 1S4P ($\sim$12\,Ah) 18650 pack --- rides through power loss on a parked machine; charge voltage strapped to 4.00\,V Li-ion for cycle life and hot-cell margin (RCA \#1 answer).
+\item \textbf{K1 normally-closed relay bypass} --- RTCM3 corrections survive a dead, hung, or physically absent MCU.
+\end{itemize}
+
+Deployment context: machine power (12/24\,V classes at ICAVE) enters the IP67 cabinet (breaker, SPD, Mean~Well DDR-60G-24); the HBOX receives regulated 24\,V, vehicle 5\,V (SD-15B-05), and \emph{raw} machine ignition through the GX16-5 bulkhead. Corrections arrive over LTE/NTRIP --- never through the GNSS --- so link recovery is always a stack power-cycle.

At 24\,V the clamp carries $<$1\,mA. \emph{The stale 100\,$\Omega$ value (audit H3) would have burned D5 and the resistor at 24\,V --- corrected on board, schematic, and fab BOM.}

+\section{Canonical invariants (engineering memory)}
+Every change to this board is checked against the project ethos. In copper, Rev 1.1 realizes them as:
+\begin{enumerate}
+\item \textbf{Power-off is the safe state.} R2 10\,k$\Omega$ pulls the Q1 gate to rail; only PA1 (\net{PWR\_CTRL}) via Q5 can enable the RTK stack. MCU absent $\Rightarrow$ stack OFF.
+\item \textbf{Never vanish, never loop.} Watchdog power-cycles the stack (modem included, via U7 fed from \net{SW\_5V}) instead of letting a unit go silent; firmware rate-limits reboots.
+\item \textbf{Corrections ride the 4G modem, not the GNSS.} RTCM3 downlink (modem DOUT $\to$ MOD1 D2 $\to$ F9P RX2) is hardwired and never touches the MCU; uplink survives a dead MCU through K1's NC contacts.
+\item \textbf{No sub-80\,$^{\circ}$C-softening material in the thermal path;} enclosure is ASA; cooling is conduction (IP67 --- no vents). Thermal telemetry: SHT40 + TMP102 (I$^2$C) + hotspot NTC (PB1) + cell NTC (charger-owned).
+\item \textbf{Backend must not black-hole a healthy unit} --- board-side contribution is honest telemetry (\texttt{\$PHLG}, charge status, temperatures) on the STREAM log.
+\item \textbf{No secrets in the repo} --- this manual and the BOM workbook carry none.
+\end{enumerate}

+\noindent\textbf{Safety-timer note:} a deep-discharge full recharge (12\,Ah @ 2.42\,A $\approx$ 5\,h) exceeds the internal safety timer --- firmware restarts the cycle via \net{CHRG\_EN} while the cell is cool and \net{BAT\_SENSE} is low.

+\subsection{Block H --- fail-safe Modo-B bypass}
+K1 (Omron G5V-1, 5\,V coil) de-energized routes F9P TX2 $\to$ 4G DIN through its \textbf{normally-closed} contacts: corrections and position flow exactly as if the watchdog were not there --- with the Blackpill hung, unpowered, or physically removed. PB5 (\net{BYP\_CTRL}) via Q6 energizes the coil to insert the MCU in-line (USART1: PA10 monitor tap, PA9 injection of \texttt{\$PHLG}). Verified against the Omron datasheet at net level: coil pins 2/9, COM 5\&6 (internally doubled), NC\,=\,1\,=\,F9P TX2, NO\,=\,10\,=\,PA9. Q6 is a Rev 1.1 (H2) BEC-map correction --- with the old BCE map it could not sink the 30\,mA coil and Modo-B injection was dead.

+\paragraph{Switchless Pro variants --- hardwired UART2 behavior.} Pro revisions differ and the difference is operationally critical:
+\begin{itemize}
+\item \textbf{Older Pros} carry an \emph{XBEE TO GPS UART} slide switch --- it must be \textbf{parked on UART1} so the (empty) on-Pro XBee socket does not sit on UART2.
+\item \textbf{Newer Pros have no switch}: the on-Pro XBee socket is \emph{hardwired to UART2}, i.e.\ permanently in parallel with the carrier's D2/D8 rail pins.
+\end{itemize}
+
+\warn{On \textbf{both} revisions the Pro's own XBee socket stays \textbf{EMPTY} --- the modem lives on the carrier's J7/J8. On switchless Pros, \textbf{never plug the Pro's ``USB XBee'' port while the unit is in service}: its FTDI sits directly across UART2 --- that is the live RTCM3 corrections downlink. Bench configuration via that port only with the unit out of service.}

+\section{Assembly \& field warnings}
+\begin{enumerate}
+\item \textbf{Switchless simpleRTK2B Pro variants} --- see \S\ref{sec:mod1}: XBee socket empty on both revisions; switch (if present) parked on UART1; \textbf{never} the Pro's USB-XBee port in service.
+\item \textbf{P11 cutoff} ships with a jumper plug when no panel switch is fitted --- an open P11 is a dead unit that looks like a field failure.
+\item \textbf{GX16 pin 3 = raw ignition.} Harnesses must feed 12--24\,V machine ignition, \emph{not} a pre-conditioned 5\,V (the DFR1015 stage no longer exists).
+\item \textbf{Battery pack}: 1S4P only, cell NTC bonded and wired to P4.3 --- the charger owns that NTC. Verify the 4.00\,V strap set (JP2/3/4) before connecting a pack.
+\item \textbf{Modules are hand-fitted} after PCBA; they are never on the JLC BOM. Seat the Pro with the notch/silk alignment --- D0/D1 reversal is fatal to the GNSS UART and invisible electrically.
+\item \textbf{IP67 discipline}: conduction cooling only; thermal pads from pack/modem hotspot to the enclosure wall; no vents.
+\item \textbf{CPL rotation spot-check} at JLC review: LTC4040 (QFN-24) and both MP1584 (SOIC-8-EP) orientations, plus Q7 --- rotation errors are the \#1 PCBA failure and H1 taught us what a reversed Q7 costs.

+\section{Order readiness \& open gates}
+\label{sec:readiness}
+\begin{itemize}
+\item \textbf{CLEARED:} H1--H4 fixed and re-verified (ERC 0 / DRC 0); M3 closed on a physical Pro; M4 (HBOX mechanical fit) verified 2026-07-07; fab package regenerated after the last save. \textbf{Bare-board order: RELEASED.}
+\item \textbf{OPEN --- M1 remainder (PCBA):} specialty + semiconductor LCSC numbers are verified and baked into the schematic (18 pinned lines); passives ride JLC auto-match at upload; DNP attributes on P3/P13/H3 confirmed in Rev 1.1. Re-confirm live stock at upload --- the pacing item is parts, not fab.
+\item \textbf{OPEN --- M2 (deliberate risk posture):} the declared fab gate --- \emph{bench-validate the LTC4040 backup transition + hot-cell charge cutoff} --- remains unmet by the TP4056 proto. Bare boards at 5\,pcs are the cheap, conscious way to retire it; \textbf{do not commit the 30-unit PCBA run before the LTC4040 block passes on real copper.}
+\item \textbf{Known-accepted:} USB service port is functional-grade (M5); D4G dim at 1.8\,V drive (L4); L7 saturation margin thin vs 2\,A modem peak (L5) --- 3\,A part next spin.

+\section*{Appendix --- BOM synchronization toolchain}
+\textbf{Single source of truth = the Excel workbook.} Flow:

+\item Edit costs/parts in Excel as quotes land (or edit the generator and re-run).
+\item \texttt{python3 tools/sync\_bom.py} --- extracts the \emph{Internal PCBA BOM} and \emph{External Integration BOM} tabs, drops section bars / blanks / TOTAL rows, escapes LaTeX reserved tokens (\&, \_, \%, \$, \#, \{\}, \textasciitilde, \textasciicircum, \textbackslash), recomputes line costs, writes \texttt{pcba\_bom.tex} + \texttt{external\_bom.tex}.
+\item \texttt{pdflatex einarboard-manual.tex} $\times2$ --- the manual ingests both snippets via \texttt{\textbackslash input\{\}}.
+\end{enumerate}
+\textbf{Drawing assets} (\texttt{assets/}): \texttt{schematic-rev11.pdf} (full A2 sheet) + \texttt{layers/} (per-layer plots) + \texttt{board-assembly-top.pdf} are exported from the Rev 1.1 KiCad files via kicad-cli (KiCad MCP) --- re-export after \emph{any} board/schematic save, or the manual silently archives stale copper. The Jun-22 \texttt{watchdog-pcb-v3-blockdiagram.svg} predates the carrier conversion and is deliberately \emph{not} included.
+KiCad board $\leftrightarrow$ schematic sync on this project is \textbf{manual} (F8 retired after the refdes-duplication incident) --- never let a BOM edit imply a netlist push.
