v1.6.1-runtime.7

Final defensive cleanup preview

This fork-specific prerelease closes the remaining defensive edge cases on top of runtime
hardening preview 6.

Changes since preview 6

• Makes UnixStreamSink the sole owner of its completion port while the worker uses a borrowed,
  non-closing handle, eliminating the stale raw-handle race during exceptional worker exits.
• Preserves the completion-port owner together with pending OVERLAPPED backing storage if a
  catastrophic drain failure prevents proving that every operation completed.
• Validates Komorebi notification arrays, indexes, and window handles without panicking on schema
  drift or malformed external data.
• Builds Komorebi focus state transactionally and publishes it only after the entire notification
  has been validated.
• Adds a malformed-schema regression test and FIFO runtime snapshot barriers to the create/reload
  window tests.

Validation

• cargo fmt --check passed.
• cargo check --all-targets passed.
• All 44 automated tests passed on Windows.
• cargo clippy --all-targets completed successfully with non-blocking style warnings.
• cargo build --release passed.
• The focused Komorebi, IOCP panic/shutdown, and window-runtime regression tests passed.
• git diff --check passed.

upstream luke-you/tacky-borders release.

v1.6.1-runtime.6

IOCP exceptional-exit cleanup preview

This fork-specific prerelease closes the final exceptional-exit lifetime gap in the Windows Unix
stream sink on top of runtime hardening preview 5.

Changes since preview 5

• Routes normal shutdown, worker errors, and callback panics through one unconditional IOCP
  cancel-and-drain epilogue before releasing any pending OVERLAPPED storage.
• Keeps newly issued AcceptEx streams under cleanup ownership before later fallible operations
  and removes streams whose WSARecv fails synchronously without creating a completion.
• Accounts for completion packets already dequeued in a partially processed IOCP batch before
  canceling and draining operations that remain queued.
• Ignores late stop packets during cleanup and intentionally preserves pending I/O backing storage
  if a catastrophic drain failure prevents proving that every operation completed.
• Adds a regression test covering callback panic while a trailing AcceptEx is pending.

Validation

• cargo fmt --check passed.
• cargo check --all-targets passed.
• All 43 automated tests passed on Windows.
• cargo clippy --all-targets completed successfully with only pre-existing style warnings.
• cargo build --release passed.
• git diff --check passed.

v1.6.1-runtime.5

Final lifecycle cleanup preview

This fork-specific prerelease completes the final lifecycle cleanup on top of runtime hardening
preview 4.

Changes since preview 4

• Drains canceled IOCP operations without a deadline before releasing their OVERLAPPED storage
  and buffers, with a shared stop flag as a fallback if posting the stop packet fails.
• Hardens config watching for notification-buffer overflow and atomic-save rename/replace patterns,
  expands the buffer, and performs an interruptible debounce before reloading.
• Moves background-service joins to a shutdown coordinator while keeping the UI message pump alive,
  then finalizes border destruction and process exit on the runtime owner thread.
• Makes theme settling stop-aware and always resolves ThemeWatcher and DisplayAdaptersWatcher worker
  ownership even when stop-event signaling fails.
• Adds focused lifecycle regression coverage for pending watcher reads, atomic config replacement,
  notification overflow, and Unix stream shutdown with pending I/O.

Validation

• cargo fmt --check passed.
• cargo check --all-targets passed.
• All 42 automated tests passed on Windows.
• cargo clippy --all-targets completed successfully with only pre-existing style warnings.
• cargo build --release passed.
• git diff --check passed.

v1.6.1-runtime.4

Final lifecycle hardening preview

This fork-specific prerelease completes the Phase 9.1 lifecycle hardening on top of runtime
hardening preview 3.

Changes since preview 3

• Reworks the config watcher around overlapped ReadDirectoryChangesW I/O with dedicated change
  and stop events, removing the shutdown race between checking the stop flag and entering a
  synchronous directory read.
• Cancels and drains the exact pending watcher request before its notification buffer,
  OVERLAPPED, or handles are released.
• Adds a finite IPC send timeout alongside the existing receive timeout so a client that stops
  reading responses cannot hold daemon shutdown open indefinitely.
• Limits malformed-config error dialogs to one active worker while continuing to log every parse
  failure.
• Owns and joins the config reload management worker during shutdown, preventing late reload work
  from recreating borders or background services after teardown starts.

Validation

• cargo fmt --check passed.
• cargo check --all-targets passed.
• All 38 automated tests passed on Windows.
• cargo clippy --all-targets completed successfully with only pre-existing style warnings.
• cargo build --release passed.
• git diff --check passed.

upstream luke-you/tacky-borders release.

v1.6.1-runtime.3

Background-service lifecycle hardening preview

This fork-specific prerelease completes the Phase 9 lifecycle hardening on top of runtime
hardening preview 2.

Changes since preview 2

• Routes config watcher, tray, and IPC reload requests through a serialized, coalescing management
  worker so a config watcher can never destroy and join itself.
• Adds an explicit stop, cancellation, unpark, and join protocol for config watchers while keeping
  malformed-config recovery observable by the existing watcher.
• Owns and stops the komorebi subscription retry thread, replacing its fixed 15-second sleep with
  an interruptible wait so repeated enable/disable cycles cannot accumulate workers.
• Tracks IPC client workers, gives idle sockets a finite read timeout, and joins all clients during
  server shutdown. Reload acknowledgements are written before reload work is scheduled.
• Replaces fixed 50 ms integration-test sleeps with border-count predicate waits and diagnostic
  timeouts.
• Adds two unit tests covering config reload request coalescing and restart after completion.

Validation

• cargo fmt --check passed.
• cargo check --all-targets passed.
• All 38 automated tests passed on Windows.
• cargo clippy --all-targets completed successfully with only pre-existing style warnings.
• cargo build --release passed.
• git diff --check passed.

v1.6.1-runtime.2

Runtime hardening preview 2

This fork-specific prerelease contains the Phase 8 runtime and graphics hardening from preview 1,
plus fixes found during real debug use on Windows.

Changes since preview 1

• Makes border and runtime timer teardown idempotent and treats already-fired or never-armed
  one-shot timers as normal cleanup state. This removes repeated misleading
  The operation completed successfully. (0x00000000) error logs when windows close.
• Preserves foreground state received during delayed border initialization without attempting to
  render before the backend exists.
• Stops retrying render and resize operations when their objects are temporarily uninitialized;
  device-loss and render-target recovery paths continue to retry normally.
• Adds run-debug.ps1 for rebuild-and-restart development and run-release.ps1 for restarting an
  existing release build.
• Documents the executable-independent configuration location and why the only config copy should
  not live under target.

Validation

• cargo fmt --check passed.
• cargo check --all-targets passed.
• All 36 automated tests passed on Windows.
• A real top-level test window produced the expected border-count transition (9 -> 10 -> 9)
  across creation and destruction, with no new error log entries.

upstream luke-you/tacky-borders release.

v1.6.1-runtime.1 — Runtime hardening preview 1

Runtime hardening preview 1

This is the first independently maintained runtime-hardening release of the
more-14-different/tacky-borders fork. It is based on upstream v1.6.0 plus the later per-side
border-offset change and remains compatible with the existing configuration format and CLI.

Highlights

• Centralizes live border ownership, animation scheduling, lifecycle reconciliation, foreground
  state, and graphics mutation on the UI runtime thread.
• Replaces per-border animation workers and polling threads with runtime timers and EnumWindows
  snapshot reconciliation.
• Coalesces reorder and location-change storms without losing their trailing state.
• Prevents an unelevated process from repeatedly attempting to decorate elevated windows.
• Routes IPC, komorebi, display-adapter, and window events through typed runtime commands.
• Hardens DirectX recovery for render-target loss and same-adapter device removal/reset.
• Uses RAII guards for Direct2D multithread locks, draw sessions, and DirectComposition surface
  draw sessions.

Validation

• 36 automated tests passed on Windows.
• Debug and release builds completed successfully.
• V2 -> Legacy -> V2 transitions completed without graphics recovery loops.
• 5,000 location changes, 5,000 reorder events, IPC traffic, and repeated reloads completed without
  linear handle or thread growth.
• Unelevated runtime behavior was checked against an elevated application window.

Physical GPU reset, monitor dock/undock, and sleep/resume fault injection were not performed for
this preview.

This is a fork-specific prerelease, not an upstream luke-you/tacky-borders release.
