P2-native PHY hard reset: DIRH not DRVH, TT11 on DP, raw SE0, event waits
Rescan vs P2KB (not generic MCU patterns): - Smart-pin order DIRL o WRPIN o WXPIN o DIRH o WYPIN (Y after enable) - Never DRVH (was forcing OUT high) - Even: P_USB_PAIR|P_OE; odd: P_TT_11 differential OTHER (not a second USB pair) - CORDIC QMUL/QDIV with GETQX stall (no soft waitx) - SETSE/WAITSE for TX empty and RX status - Drop RX purge + long turnaround (was eating FS ACK) - Bus reset: raw DRVL both pads 20ms then re-pair (Y=1 SE0 failed to pull DP in probe) - Harness: raw pad probe + pair_probe before host cog Live: baud $CF5C, SOF ~1kHz, Zidle shows J on fallback; SETUP ACK still timeout. leaf check-in: 5bbaec1d3f user: refaqtor tags: trunk | |

Design reset: P2-native rules (not generic MCU USB)
Document silicon-first constraints: Force-1 host cog, P_USB_PAIR ownership, CORDIC for baud, no soft-64 divides, event waits, local RX echo, multi-pair emulators. FIT thrash was structure failure; stop treating P2 like other chips. check-in: ecc3b2b00f user: refaqtor tags: trunk | |

Host cog rewrite: CORDIC baud/timing, hard FIT $1F0, no soft divides
Admit prior FIT thrash was soft 64-bit math and sprawl, not CORDIC. QMUL/QDIV compute baud X and us/ms bases in ~120 clocks of waitx. Lean register file + primitives; Spin still owns control orchestration. check-in: 00533baf63 user: refaqtor tags: trunk | |

USB PHY: dual WRPIN, TX IN-race fix, drain local RX echo
- Configure both even/odd pins with P_USB_PAIR|P_OE (silicon requirement) - TX: wait after WYPIN before polling buffer-empty; post-EOP gap - RX: drain local TX echo before waiting for device ACK - Spin supplies baud X=$CF5C; longer hub reset/recovery Still: SETUP DATA0 gets no ACK (timeout) on 34/35 and 38/39 — next dig deeper. check-in: c653e7b452 user: refaqtor tags: trunk | |

Control xfer: add missing IN/OUT tokens; stage fail logs; hub note
GET_DESCRIPTOR failed at SETUP data/ACK (hs=0,crc=1) on both 34/35 and 38/39 with hub+thumb. SOF live. Next: RX handshake / VBUS power verification. check-in: 69c1bf1894 user: refaqtor tags: trunk | |

Bring-up on P81svj44: load, VBUS, SOF live; GET_DESCRIPTOR pending
Harness tries 34/35 then 38/39 with GET_DESCRIPTOR probe. Host cog starts, SOF ~1 kHz confirmed. Fix Spin baudX display (was 32-bit overflow). Device descriptor still fails (CRC/status -2) — need 5V/host path debug next. check-in: 525aaa82b7 user: refaqtor tags: trunk | |

Board map: Serial Host base32; top USB prefer 34/35 then 38/39
Primary host pair 34/35 with VBUS EN 33 (pretend top=ch1). Fallback pair 38/39 EN 37 if device not found. Proto gangs 40/48 and 41/49 unchanged. check-in: 61a6333e24 user: refaqtor tags: trunk | |

Greenfield USB FS host scaffold: one-cog PHY + Spin orchestration
Implement original (non-community) host stack for P2 smart-pin P_USB_PAIR: hub RAM mailbox ABI, compact PASM primitives, Spin2 control/bulk/int paths, HID/MSC/CDC class stubs under -D gates, self-test harness with debug() metrics. Research/design/hardware docs included. Ignore .bin build products. Pin map still provisional pending board confirm on P81svj44. check-in: c2f0264ef7 user: refaqtor tags: trunk | |

Seed mission prompt and 55-phase ticket index
Heed prompt.md: Fossil-only P2 USB FS Host (HID/MSC/CDC) one-cog driver with self-test harness. Ticket ledger covers research through deliverables; TICKETS.md maps NNNN titles to Fossil UUIDs for live links. check-in: 860217df99 user: refaqtor tags: trunk | |
