Alex v0.1.29

First stable release of the 0.1.29 line. It includes all changes from the
0.1.29 betas plus the V1 activation, reliability, and supported-platform work
below.

Added

• Programmable middleware with an explainable Fable-to-Sol fallback. Typed,
  regex-first rules can match harness, model, provider, status, response
  headers, and body content; reroutes are session-scoped, persisted, visible in
  traces, and manageable from the CLI, web UI, and macOS rule editor. The
  built-in preset moves an explicit Fable refusal to high-effort GPT-5.6 Sol.
• LAR-backed trace storage and lazy browsing. Crash-recoverable archives,
  resumable migration from existing gzip bodies, bounded body reads, cursor
  pagination, lazy transcript turns, sanitized export/replay fixtures, and a
  reproducible 55,000-trace/9.4-GB scale gate keep large trace collections
  usable.
• First-class CLIProxyAPI integration in both directions. Alex can route
  through an existing CLIProxyAPI instance, and CLIProxyAPI can route into
  Alex with scoped credentials, capability negotiation, correlation headers,
  streaming/tool-call preservation, and loop rejection. Web and macOS
  onboarding can probe and configure the upstream path.
• Shared activation path. alex doctor, the local web UI, Linux user
  services, and deterministic packaged smoke tests cover onboarding, health,
  middleware, routing, traces, restart, upgrade, and rollback.
• Public interactive walkthroughs. Three static, source-checked demos cover
  cross-harness routing, Fable-to-Sol failover, and asking a second model. The
  site supports keyboard/mobile use, reduced motion, no-JavaScript fallbacks,
  and privacy-safe conversion events.
• Cross-harness session resume. Captured Pi, Claude, and Codex sessions can
  be forked into another supported harness while retaining trace lineage.

Changed

• The product and runtime are now Alex. User-facing copy, binaries, service
  identifiers, configuration, installers, package metadata, and the macOS app
  use the Alex name; fresh installs have no legacy compatibility layer.
• Onboarding is resumable and reversible. Users can move between harness,
  provider, imported credentials, existing accounts, and new-account flows
  without stale selections or test state; detected credentials require an
  explicit confirmation before import.
• The default Fable fallback now intercepts any structured Anthropic SSE
  refusal, routes to high-effort GPT-5.6 Sol, and keeps the replacement route
  for the stable session for 24 hours.
• Middleware Settings now shows recent real trace matches and execution results
  instead of presenting a synthetic Test button.

Fixed

• Release packages now exercise the installed Linux service and macOS app/CLI
  before publication, and the stable workflow builds one complete
  checksum-verified manifest before crates, GitHub Release, Sparkle, or
  Homebrew promotion.
• Reset and first-run flows safely rediscover credentials, recreate private
  configuration paths, and return provider-less installs to onboarding.
• Codex login and account routing preserve existing identities and clearly
  distinguish imported, existing, and newly authenticated accounts.
• Linux and macOS service upgrades replace the active daemon without leaving a
  duplicate process, and packaged rollback preserves state and trace history.
• Editing the built-in middleware rule now always updates its existing ID
  rather than occasionally creating a second custom rule from a stale sheet
  state.
• Claude onboarding now shows the opt-in --settings launch command directly
  after connection.
