# bambu-nfc Library Implementation Plan
|
||
|
||
> **For agentic workers:** Use TDD. Spec: `docs/superpowers/specs/2026-08-23-bambu-nfc-library-design.md`
|
||
|
||
**Goal:** Go module that parses filanfc-dump/v1 zips into Bambu tags/spools and derives MIFARE Key-A from a chip UID.
|
||
|
||
**Architecture:** Public packages `dump` (JSON/zip), `mifare` (1K layout), root `bambunfc` (HKDF, block parse, Merge).
|
||
|
||
**Tech Stack:** Go 1.25, stdlib `crypto/hkdf`, `encoding/json`, `archive/zip`.
|
||
|
||
## Global Constraints
|
||
|
||
- Module `git.s1d3sw1ped.com/s1d3sw1ped/bambu-nfc`
|
||
- Brand on success: `"Bambu Lab"`
|
||
- HKDF: IKM=UID, salt=`9a759cf2c4f7caff222cb9769b41bc96`, info=`RFID-A\0`, 16×6 Key-A
|
||
- Diameter float32 at block 5 offset 8; tray UID 16 raw bytes hex
|
||
- Required dump sectors for a Bambu parse: 0, 1, 2 (`sectors_fail` is sector indexes)
|
||
- `go test -race ./...`
|
||
- Fixtures from dump-app `docs/dumps/` → `testdata/`
|
||
|
||
Tasks: (1) module + mifare (2) dump JSON/zip (3) KeysA (4) ParseImage/ParseDump/ParseZip (5) Merge (6) testdata + README.

Executing in this session per user "do it".
