olwb 2.0.0

Added

• Instant liners: > olwb -i and Alt-Shift-i open a memory-only liner
  whose captures can use selection, send, export, and issues workflows.
  /save <name> promotes it; switching liners, closing, resuming, or exiting
  discards it without changing durable active-liner state.
• Explicit entry modes: bindable launch, resume, and instant Lua
  functions default to Alt-o, Alt-Shift-o, and Alt-Shift-i without
  overwriting existing user bindings.
• Per-invocation autostart: a non-empty OLWB_AUTOSTART opens olwb for one
  micro process, including file-backed launches, without persisting the option.
• Open-view queries: /open candidates now accept repeated label:
  tokens (ANDed against liner labels) plus case-insensitive text matched
  against liner names, ids, and descriptions.
• Command aliases: every top-level slash command has a collision-checked
  single-letter alias shown beside it in the live /? menu and help.
• Errors in the feed: workflow failures (/send, /issues draft,
  /issues file) now land as persistent ⚠ error-labeled messages — in the
  destination's into liner, the issues liner, or a fallback olwb-errors
  liner — carrying full stderr, kept evidence paths, any partially-filed
  issue URLs, and the retry command. The info bar still flashes the short
  version.
• Failure evidence kept: failed issues jobs save full stderr to
  <datadir>/issues/<id>.err.log and record last_error/last_error_ms on
  the manifest (cleared on a later success); /issues list shows the last
  error under each draft.
• Progress indicator: background jobs show an animated spinner in the
  bottom bar (and the /issues list overlay) with what is running and
  elapsed time, e.g. ⠹ filing 7 issue(s) on o/r 12s, driven by a
  main-state-safe sleep ticker.
• /issues open [<id|latest>]: opens a draft's filing script in a new
  tab for the review step — editable, saveable, no more retyping the path
  from the /issues list overlay.
• Label preflight: generated filing scripts create any missing labels
  (create-if-absent, never --force) before the first gh issue create,
  so a label the drafting model invented no longer aborts the whole run.

Fixed

• Shared destination sessions: state.json saves now lock and merge
  per-key dest_sessions changes, preserving additions and deletions made by
  other micro instances using the same data directory.
• Async sends: stale-session retries reuse the original payload and
  provenance; completion clears only the selection sent by that attempt, so
  edits and selections made while it runs survive.
• Issue filing: /issues file refuses a second invocation while an issues
  job is running, preventing duplicate GitHub issues.

Changed

• Bare input without a liner: submitting text with no active liner now
  turns it into a live /open query for Tab selection instead of creating a
  notes liner and storing the text there. Slash commands and input within an
  active liner keep their existing behavior.

Docs

• CONTRIBUTING.md: external contribution policy — trivial
  comment/docstring-only PRs are not merged; deeper contributions (multiple
  issues, code, behavior changes) are welcome.
