GitHub Copilot 1cfced1052 webterm: fix screenshot tile bootstrap and add request logging 
Fix screenshot generation for requested dashboard route keys by preserving non-empty route_key lookups when no session exists yet, allowing lazy session creation instead of returning 404.

Add server-side observability with HTTP request logs (method, URI, status, bytes, duration, remote address) and websocket connection lifecycle logs for connect/disconnect and unexpected read errors.

Update README title/positioning and expand feature bullets to document Ghostty WASM rendering and mobile/touch keyboard support.

GitHub Copilot c8040e5938 go: harden session cleanup path 
Ensure SessionManager.CloseAll fully removes session and route mappings by reusing CloseSession for each tracked session ID.

Tighten coverage test assertions to verify CloseAll removes both sessions and route-key mappings, guarding against stale state regressions.

GitHub Copilot 4e90b65c6b ci: tighten release workflow cleanup policy 
Rationalize the release workflow by adding top-level concurrency to avoid overlapping publish runs for the same ref and by restricting cleanup jobs to tag refs only.

Keep ci.yml as the PR/main validation gate while docker.yml remains focused on release publishing and post-release maintenance.

GitHub Copilot 3d4dab2359 Finalize Go-only migration, runtime hardening, and CI/container optimization 
This commit consolidates the full repository transition to a Go-first codebase and captures the follow-up performance/reliability work completed in the same stream.

Highlights:
- Remove Python implementation and test suites (, , , ) and retire Python-specific docs/instructions.
- Move and standardize static web assets under , updating Bun/TypeScript build paths and server static resolution logic.
- Rewrite developer workflow to Makefile-first Go targets (vet/test/race/coverage/fuzz/build) and align repository guidance/docs accordingly.
- Update Docker and CI/CD for leaner artifacts:
  - switch to Alpine-based multi-stage build with stripped Go binary
  - install only minimal runtime deps (, )
  - tighten Docker build context via
  - ensure workflows build/publish the  target.
- Improve runtime correctness/latency and reduce duplication:
  - explicit WebSocket outbound frame typing (text vs binary) instead of payload-byte heuristics
  - SSE activity fan-out outside global lock and safer subscriber lifecycle
  - shared session output/snapshot helpers to reduce duplicated logic
  - restart-safe channel lifecycle for Docker watcher/stats start-stop-start flows
  - faster screenshot cold-start path (poll-until-ready within timeout vs fixed sleep).
- Add/expand regression coverage for the above lifecycle and helper paths.

Validation run:
- bun run build

GitHub Copilot 065de286fb refactor: standardize Go layout with internal terminalstate 
Audit findings: cmd/webterm and webterm package were acceptable, but terminalstate
was an internal implementation detail exposed as a public package.

Changes:
- Move go/terminalstate -> go/internal/terminalstate
- Update imports to github.com/rcarmo/webterm-go-port/internal/terminalstate
- Keep package name terminalstate unchanged

Resulting package layout:
- github.com/rcarmo/webterm-go-port/cmd/webterm
- github.com/rcarmo/webterm-go-port/internal/terminalstate
- github.com/rcarmo/webterm-go-port/webterm

Validation:
- go test ./...
- go test -race ./...
- go coverage check remains 80.9%
- make check

GitHub Copilot 5aa9eb9426 chore: incorporate relevant agentbox skel files 
Add relevant skeleton files from rcarmo/agentbox/skel for this repo:
- .github/workflows/ci.yml (Makefile checks + conditional Go tests)
- .github/instructions/{00-project-detection,docker-image,frontend-bun,go,python}.instructions.md

Instruction files were adapted where needed to match current workflow names
and repository layout (Go module under go/, Docker workflow filename).

Validated with make check and go test ./... .

GitHub Copilot 674e62d983 refactor: upgrade go-te to v0.1.0, remove C1 normalization 
go-te v0.1.0 fixes the ByteStream C1 bug (Latin-1 fallback for
invalid UTF-8 bytes), so NormalizeC1Controls is no longer needed.

Removed:
- NormalizeC1Controls function and its tests/fuzz target
- utf8Buffer field from TerminalSession and DockerExecSession
- C1BUG.md (fix shipped upstream)

The handleOutput pipeline now does: FilterDA → replay → tracker → connector
(was: FilterDA → NormalizeC1 → replay → tracker → connector)

All tests pass with -race. 13 fuzz targets remain.

GitHub Copilot 307a8cc312 docs: add go-te C1 ByteStream bug report (C1BUG.md) 
ByteStream.Feed() in UTF-8 mode permanently stalls on raw C1
control bytes (0x80-0x9F). DecodeRune returns RuneError, the loop
breaks, and the bad byte stays in the buffer forever — blocking
all subsequent input and leaking memory.

Stream.handleGround() has correct C1 handlers but they are
unreachable through ByteStream. Includes reproduction case and
suggested fix (Latin-1 fallback for invalid UTF-8 bytes).

GitHub Copilot fd6c1c4e0d feat: complete Go port with go-te terminal emulator 
Full Go implementation under go/ replacing Python pyte with go-te:
- HTTP server with WebSocket protocol, SSE, screenshot SVG rendering
- PTY terminal sessions and Docker exec sessions
- Docker watcher (label-based container discovery + event stream)
- CPU stats collection with sparkline SVG rendering
- Session manager with TwoWayMap routing and replay buffers
- C1 normalization, DA filtering, identity generation, theme palettes

Audit fixes for 9 concurrency/correctness issues:
- HTTP transport leak: shared client pool for Docker socket calls
- WebSocket concurrent writes: all writes routed through send channel
- Closed channel panic: atomic.Bool guard on enqueueWSData
- GetFirstRunningSession: use UnsafeForward under SessionManager lock
- NewSession TOCTOU: re-check routeKey after re-acquiring lock
- waitErr data race: protect with mutex in both session types
- Replay buffer fragmentation: copy to new slice on eviction
- go-te dirty tracking: check screen.Dirty before incrementing counter
- Identity modulo bias: rejection sampling for uniform distribution

All Go tests pass (including -race). Python baseline unchanged (397 tests).

GitHub Copilot 10ffb9d8cc docs: consolidate pyte patches documentation 
Rename ink-clear-fix.md → pyte-patches.md and rewrite as a
comprehensive reference for all pyte monkeypatches:
- Patch 1: CSI S/T (SU/SD scroll) — primary ghost content fix
- Patch 2: Alternate screen buffer (DECSET 1049)
- Patch 3: Ink partial clear expansion (secondary defense)

Update README.md Known Issues to reflect the actual fix approach.
Update ARCHITECTURE.md to document alt_screen.py and pyte patching.

GitHub Copilot 207eddc922 fix: implement CSI S/T (scroll up/down) to fix ghost content in screenshots 
pyte 0.8.2 does not handle CSI S (SU — Scroll Up) or CSI T (SD —
Scroll Down). When TERM=xterm-256color, tmux sends CSI n S for bulk
scrolling instead of DECSTBM+index. pyte silently ignored these
sequences, leaving old content in the screen buffer — visible as
ghost content in SVG screenshots.

Fix: monkeypatch pyte's CSI dispatch tables to map S→scroll_up and
T→scroll_down, and implement both methods on AltScreen with proper
scroll-region (DECSTBM) support.

Adds 6 tests for SU/SD functionality.

GitHub Copilot 3ba8c7f352 fix: expand Ink partial clears to prevent ghost content in screenshots 
Ink (React CLI framework) clears its output using repeated EL2+CUU1
sequences, one per previously-drawn line. When /clear resets Ink's
internal line counter, the next frame only erases a few lines instead
of the full previous output. In a real terminal the old content is in
scrollback and invisible, but pyte's fixed-size screen retains it,
producing ghost content (e.g. duplicated prompts) in SVG screenshots.

Added AltScreen.expand_clear_sequences() which detects runs of 3+
EL2+CUU1 pairs that don't reach row 0 and extends them to erase all
lines up to the top of the screen. Both DockerExecSession and
TerminalSession call this before feeding data to pyte.

Also made on_session_end() idempotent (contextlib.suppress KeyError)
to prevent a race when close_session() and natural session exit both
call it.

Added docs/ink-clear-fix.md with root cause analysis, byte-level
explanation, and reproduction script.

GitHub Copilot b87a698438 fix: properly clean up sessions when Docker containers are destroyed 
- close_session() now calls on_session_end() to remove the session from
  sessions dict and routes, preventing zombie entries that persist after
  the container is gone
- _remove_container() now closes the active session before removing the
  app from apps_by_slug/apps, so session cleanup can still reference the
  app during teardown
- Updated and added tests to verify session tracking cleanup
