• Package-correct library-backed parts were added for: U1, U2, U3, U7, U8, U10, U11, U13, U15, U31, U32, LED1, J2, J3, J4, J5, J6, J7, J8, J10, J11, J12, and J13.
• The old placeholder instances did not delete cleanly because several imported placeholders have blank/hidden designators even though their designator is embedded in the part name. The schematic now shows 61 components rather than the intended 38.
• All intended nets still show 0 schematic connections. Therefore the full mismatch against the net map is: every intended pin-to-net assignment is currently missing until rewiring is performed.
• ERC/check run at 2026-07-04T21:52:56Z reports 585 open/warning checks, dominated by floating pins on both package-correct replacements and leftover placeholders.
• J14 geometry is now resolved and implemented on the PCB: three bottom-side gold pads, order V+ | SENSE | GND viewed from bottom with battery/XT60 edge west, 10×15 mm each, 20 mm pitch, centered at X=0/Y=+45 mm. R40=10 kΩ and D1=SMBJ16A-TR were added for CHG_SENSE/TVS support.
• Important cleanup note: the hidden/placeholder instances still carry many net memberships. Do not delete them blindly without first transferring their nets to the package-correct replacement instances.
• J14_CHARGE_PADS custom component was created and added as J14. Net bindings are now: J14.VPOS→VBAT_RAW, J14.SENSE→CHG_SENSE, J14.GND→GND. Old Pogo_J14 had no remaining net membership to transfer, but it could not be deleted because the delete tool accepted the request without removing the blank-designator component.
• J14 copper duplicate check completed: before cleanup there were two pad sets at the specified Bottom coordinates (one J14-owned footprint set plus one standalone set). The standalone pads were deleted; read-back now shows exactly one J14-owned set of three Bottom rectangular pads at (-20,45), (0,45), (+20,45), each 10×15 mm.
• Batch A power-tree wiring was started on usable designators: U13, U10, U11, U15, U8, J14, R40, and D1. Missing exact/blank-designator power parts remain unresolved and were not force-wired.

• Board center is origin.
• Pad row centered at X=0, Y=+45 mm toward the LED/south edge, clear of bottom-side J9.
• Bottom view, battery/XT60 edge = west: pad order is V+ | SENSE | GND.
• Pad size is 10×15 mm each, with long axis perpendicular to row.
• Pitch is 20 mm center-to-center, so V+ to GND span is 40 mm.
• Frame magnet pockets use opposite polarities for anti-reverse keying.

• J14_VPOS_Gold_Pad at (-20 mm, +45 mm), Bottom, 10×15 mm.
• J14_SENSE_Gold_Pad at (0 mm, +45 mm), Bottom, 10×15 mm.
• J14_GND_Gold_Pad at (+20 mm, +45 mm), Bottom, 10×15 mm.
• Bottom silk label: J14: V+ SENSE GND.

• R40: 10 kΩ 0402 generic resistor, CHG_SENSE to VBAT_RAW.
• D1: SMBJ16A-TR TVS, VBAT_RAW to GND at the charge-pad domain.

• J14_CHARGE_PADS exists with pins VPOS, SENSE, GND.
• J14.VPOS is connected to VBAT_RAW with R40:P2 and D1:K.
• J14.SENSE is connected to CHG_SENSE with R40:P1.
• J14.GND is connected to GND with D1:A.
• Old Pogo_J14 still remains as a blank-designator placeholder. Delete attempts using Pogo_J14, Pogo_J14::136a1d39, and full UID 136a1d39-30be-4445-a2cc-bf7b7e21412d reported success but did not remove it; internal feedback was submitted.
• Additional delete retry after user request still failed to remove old Pogo_J14. It remains electrically inert with zero net membership. J14 keyword ERC still reports the two Pogo_J14 floating pins plus its missing-footprint warning; J14_CHARGE_PADS itself is net-bound.

1. Clean up leftover placeholder instances by a direct/UID-based delete path or revert/retry replacement if supported.
2. Import/create exact missing parts: LM74722QDBVRQ1, MAX16151AUB+T, TPS3890ADRYR, TPS3839K33DBZR, DPS310XTSA1, TPS54540DDAR, ESP32-C5-WROOM-1U-N16R8, NRC7394, MTFC8GAKAJCN-4M IT, Molex 502443-0470, XT60PW-M, KMR221GLFS, and CEM-1203(42).
3. Convert J14 from standalone pad nodes plus placeholder into a proper 3-terminal custom footprint/symbol or otherwise bind pads to schematic nets.
4. Rewire package-correct pins against the net map in batches, preserving hidden placeholder net memberships until each replacement is fully wired, then rerun ERC after each batch.
