feat: udprelay subcommand + HOSTDEMO_LISTEN env for cross-subnet host verification
...
- udprelay [listen] [butler_ip] [src_ip]: generic UDP/31772 relay on Windows,
forwards client frames to Butler with spoofed source IP (default .113,
bypasses AECH firmware filter), relays Butler replies/broadcasts back
- hostdemo: HOSTDEMO_LISTEN separates actual socket bind from advertised IP
(Ubuntu binds 0.0.0.0:31772, frames still claim 192.168.123.113)

fix: build_rdm_frame checksum off-by-one (summed 1 extra byte incl. stale template checksum)
...
Default mode RDM discovery got 0 responses because the template-based builder's
checksum range was 0x3C..0x3C+msgLen (includes the old checksum slot) instead of
0x3C..0x53+PDL. build_rdm_frame2 was already correct (used by show mode).

fix: default mode claim now uses proven minimal recipe; bind52/prelude default off (toxic)
...
Root causes found via ablation on cold Butler:
1. bind52x4 ending with 0000(unbind) -> Butler enters multi-minute AECH-refusing
state (recovers spontaneously); now gated behind HOSTDEMO_BIND=1
2. 45s broadcast prelude also toxic (PRE=45 claim FAIL / PRE=0 PASS);
gating hypothesis ('Butler needs 13+ announce rounds') falsified;
HOSTDEMO_PRE default now 0
3. AECH requires announce144 identity first: skip2 (no ident) FAIL,
per-round announce144 + claim -> PASS
4. IDENT102 patch offset bug: writing IP at 0x1C corrupted MAC high bytes
(IP already at 0x1A in const) - patch removed
5. Claim wait loop now drains socket buffer and uses 700ms wall clock
(was 10x5ms recv which expired on buffered self-broadcasts)

feat: show mode claim frame now fully self-constructed (zero opaque blocks)
...
build_claim_frame(): 552B AECH claim from scratch - envelope + host IP/MAC +
AECH + zeroed opaque regions + nonce@0x88 + B12@0x8C. Verified on real Butler:
AERE PASS, 3 fixtures online. Show mode no longer needs claim_h112 template.

feat: decode remaining frame fields (claim/AERE/announce/discovery-resp/EUCE/events)
...
- claim 552B: full layout; 240B opaque blocks proven UNCHECKED by Butler
(CLAIM_ZERO=1 ablation: zeroed blocks -> AERE still PASS) -> claim can be
built from scratch with zeros
- AERE 552B: Butler IP/MAC/netmask, fixture UID@0x33, slow counter@0xB1/0xB5,
resp@0xC0; only resp+counter vary across captures
- announce 644B: session GUID, UTF-16BE show-file path, full timestamp
@0x239 (y/mo/d/h/mi/s/ms; live sample decodes to 22:52:50.992 matching SL
session), ephemeral port@0x25C, enable flags
- discovery-resp 217B: device name, serial blob, network block, config block
- EUCE 540B: 'EUCE' magic, version 5, username+computername+GUID, host MAC
- event_b: type=4 1084B RDM-uplink frame identified (RDM response @0x3C)
- analyze: new 'xor' subcommand with periodicity analysis

fix: dual-port DMX output in show mode; AERE claim verification; SHOW_DIAG mode
...
- Root cause of 'steady white': fixture on Butler port2, our data only went to port1
(port data regions are independent: port1 @0x3C, port2 @0x23C)
- show mode now mirrors pattern to both ports; SHOW_DIAG=1 gives 3s off/on blink test
- Claim now verifies AERE response and warns on failure
- Docs updated with port layout note; README updated

feat: crack all DMX/RDM frame fields; show mode now fully self-constructed
...
- analyze subcommand: offline replay/template field variance, diff, counter analysis
- DMX header fully decoded: port mask @0x20, port lens u16LE=512 @0x34/0x36, counter +1/frame
- RDM request frame fully decoded: counter=0, 0x20=02, 0x2A=0xCC, msgLen=24+PDL,
checksum=0xCC+sum(0x3C..0x53+PDL) @0x53+PDL, pair copy rules
- Fix historical misreadings: RDM always starts @0x3C (not variable); no session-level
frame check exists - earlier failures were wrong template + checksum off-by-one
- show mode: build_dmx_frame/build_rdm_frame2/rdm_pair_copy, zero template dependency
- Decode 47B register response and 42B event frames; doc enet_protocol_current.md rewritten

feat: show mode for standalone 1-32 rainbow DMX + RDM status polling
...
- Merge show/hybrid paths: use dmx_a template for DMX payload and replay-extracted SL frame skeleton for RDM.
- HOSTDEMO_MODE=show runs indefinitely when secs=0; wave period slowed for smoother breathing.
- Update README with show mode usage.
