Backend (crates/ericrfb-proxy):
- Session cookie now persisted in AppState for device API calls
- New kvm.rs with three REST endpoints:
GET /api/kvm/ports — scrapes kvm.asp, returns port config as JSON
PUT /api/kvm/ports — saves port names, hotkeys, visibility, count
POST /api/kvm/switch — switches active KVM port via home2.asp
- HTML scraping extracts form values from predictable firmware HTML
Frontend (crates/ericrfb-frontend):
- New shell.ts: sidebar navigation with page routing pattern
(Console, Ports — extensible for Virtual Media, Users, etc.)
- Console refactored into pages/console.ts with mount/unmount lifecycle
- Port switcher dropdown in toolbar (fetches port list, switches on change)
- WebSocket auto-reconnects after port switch
- New pages/ports.ts: editable port configuration table
- Port count, key pause duration, per-port name/hotkey/show-in-console
- Save, reload, and per-port switch buttons
- Active port highlighted
- Dark theme sidebar with active state indicators

The mapping was built assuming keynr followed physical keyboard order
with Escape=0. In reality, KeyTranslator.java maps Java VK_* codes to
keynr values with a different layout:
- keynr 0 = Backquote (not Escape)
- keynr 59 = Escape
- keynr 27 = Enter (not 40)
- keynr 40 = Backslash (not 42)
This caused the number row and QWERTY row to be off by 1 (Escape
was inserted at position 0, pushing everything). The home row
(CapsLock=28, A=29...L=37) happened to align by coincidence, which
is why 'g'(33) worked but 'r'(should be 18, was 19=T) didn't.
Also fixes: F1-F12 off by 1, PrintScreen/ScrollLock/Pause off by 1,
numpad operator keys swapped with numpad 7/8/9.
Corrected both Rust (input.rs) and TypeScript (input.ts) mappings
to match the authoritative KeyTranslator.java VK→keynr table.

When pal_selector=0 (no predefined palette), the Java code reads two
separate full bytes for the 2-color palette (line 421-422 of
ByteColorRFBRenderer.java). We were reading one packed byte and
splitting into nibbles, consuming 1 byte too few and misaligning all
subsequent reads including the zlib compressed data.
This caused "deflate decompression error" on stream 1 because the
zlib header (78 da) was offset by 1 byte.

codec/iip.rs:
- TileCache: (fb_width/16 × fb_height/16) tiles, 8 versions × 256 bytes
each, matching t.java's (8, 16*16) allocation
- TileEntry: versioned read/write at byte offsets within tile data
- decode_iip() handles all 4 modes from the control byte:
- Mode 0/12 (cache-read): tile control bytes select which cached
version of each 16x16 tile to display, no new pixel data on wire
- Mode 4 (write-only): Tight-decoded pixel data written to cache
- Mode 8 (update+read): conditionally writes new data to cache
(bit 7 of control byte = 0 means update), then reads from cache
- Tile control bytes compressed via zlib (varint length) when >= 12
- Sub-types 1-4/8 map to bit-depths 1/2/4/4/8 bpp
- Cache resized on framebuffer resize (ModeChange msg 128)
Wired into session dispatch for encoding 9. Not advertised in default
encoding list — only active if explicitly requested.
codec/tight.rs: made get_or_init() pub for IIP's zlib access.
39 tests passing.

Frontend reconnection:
- WebSocket auto-reconnects with exponential backoff (1s → 30s)
- Re-authenticates with OmniView to get fresh APPLET_ID on reconnect
- Credentials stored in sessionStorage for automatic re-login
- Status bar shows connection state and reconnect countdown
- Disconnect button returns to login screen
Encoding 10 (Raw with tile interleave):
- codec/raw_tile.rs: decodes encoding 10 per ByteColorRFBRenderer.for()
- Flag byte bit 0 selects plain raw vs 16x16 tile-interleaved data
- Deinterleave handles edge tiles smaller than 16x16
- Wired into session dispatch
- 2 unit tests
39 tests passing.

Simplified deploy steps — rsync directly to final paths using
sudo rsync on the remote instead of temp-file staging.

publish.yml — triggered on push to main, two parallel jobs:
frontend:
- Builds Vite frontend (fnm + npm ci + npm run build)
- Rsyncs dist/ to gitea_ci@UI_HOST:UI_PATH/
- Rsyncs nginx config to UI_HOST, creates sites-enabled symlink,
runs nginx -t && systemctl reload nginx
backend:
- Builds release binary (cargo build --release -p ericrfb-proxy)
- Stops blekin.service on WS_HOST
- Rsyncs binary to WS_HOST:/usr/local/bin/ericrfb-proxy via sudo rsync
- Rsyncs systemd unit to WS_HOST:/etc/systemd/system/blekin.service
- Enables and starts the service
asset/nginx/blekin.kosherinata.internal.conf:
- Serves static frontend from UI_PATH
- Reverse proxies /api/ to frootmig:3000 with WebSocket upgrade
- 24h read/send timeouts for long-lived KVM sessions
asset/systemd/blekin.service:
- Runs ericrfb-proxy with BLEKIN_HOST=10.3.0.130
- Restart on failure with 5s backoff

codec/hextile.rs:
- Full Hextile (encoding 5) decoder per ByteColorRFBRenderer.int()
- Handles: Raw tiles, BackgroundSpecified, ForegroundSpecified,
AnySubrects, SubrectsColoured flags
- Background/foreground colors persist across tiles
- 4 unit tests covering all subencoding paths
framebuffer.rs:
- Added fill_rect() for Hextile background/subrect fills
session.rs:
- Wired Hextile encoding 5 into the rect dispatch
examples/record.rs:
- 30-second (configurable) recording session
- Saves 1 PNG per second to out/ directory
- Requests encodings [5, 1, 0] (Hextile, CopyRect, Raw)
- Tested against real OmniView: 10 frames in 10s, no errors
27 tests passing.

The OmniView defaults to 16bpp when no SetPixelFormat is sent.
The Java applet sends SetPixelFormat (msg type 0) at
ByteColorRFBRenderer.new() line 76 to request 8bpp RGB332
(bpp=8, depth=8, true_color, red_max=7, green_max=7, blue_max=3,
shifts 0/3/6). Without this, pixel data arrives as 16bpp pairs
that produce green stripe artifacts when interpreted as 8bpp.
Verified: snapshot now matches the reference screenshot from
http://10.3.0.130/screenshot.jpg (dark screen with "Free" label).

Fixes CI fmt check failure — rustfmt wants multi-line assert_eq! for
long struct literals and the varint roundtrip assertion.

Cross-referenced every wire-format claim against rc-src and corrected
several errors that would have caused stream desync during implementation:
- rect header is 4×u16 + i32 (12 bytes), not varints + u8
- ping payload is i32 (4 bytes), not 1 byte
- PointerEvent is 8 bytes (includes trailing extra_u16)
- ServerInit is 19 bytes, not 16
- pixel-format struct is variable-length, not fixed 25 bytes
- string primitive uses modified-UTF-8, not ISO-8859-1
- bandwidth probe is read-only (no echo response)
- Phase 1 uses sync Read traits (async deferred to Phase 2)
- corrected all stale line-number references in ac.java/aw.java
