EvidenceForge v2.2.0a1

First alpha of the planned 2.2.0 release. Introduces EvidenceForge Studio,
a standalone macOS application, and portable scenario and pack releases.
Existing CLI and native chat-skill workflows remain available. Log generation
remains deterministic and makes no LLM calls.

EvidenceForge Studio

• Introduce a desktop workspace for authoring scenarios and packs, validating
  inputs, running generation, inspecting bundles, and reviewing evaluations.
  Studio uses a Tauri/React interface with a durable local service
  (a271102f, 75d09d0d).
• Add project-aware libraries, folders, filters, saved views, contextual
  search, cloning, and remembered disclosure states. Keep authoring conversations
  attached to their scenarios (3a76eac7, eaf3666b, f900abab, 36b67ffc,
  a2586655, 656bb749).
• Add environment inspection, exact pack-version selection, guided asset
  editing, and optional project/scenario configuration contexts
  (d81719fc, d61fb65c, 388ac686, 5ce4338f).
• Import scenarios and portable packs with dependency review, and discover
  existing generation bundles produced outside Studio
  (0d7bacc7, 8c4e4e7d, 46d9ab70).
• Improve authoring controls, model selection, validation feedback, native file
  dialogs, source navigation, and visibility of chat failures
  (e2d0b0a6, 53c89678, 87dd6258, 53d0681a, f52d3f8f).

Generation and evaluation

• Freeze generation inputs when jobs are queued and maintain durable job
  histories, keeping run outcomes separate from subsequent input changes
  (85c25f43, 75d09d0d, c33f6f93).
• Bring runs, bundles, and evaluation results together in scenario workspaces.
  Link scores to saved evaluation details and show recent outcomes without
  requiring every run to be expanded (1e7ececd, 973b5996, b21ab793,
  111947dd, c27c5b24).
• Predict generation resource requirements and reuse cached forecasts. Show
  recorded generation sizes and the specific log types present in bundles
  (d5fbae3c, 46cccbd1).

Portable scenario and pack releases

• Introduce Schema 3 lifecycle metadata, editable drafts, immutable local
  releases, exact ancestry, release notes, and linked upgrades. Earlier
  scenario schemas 1/2 and pack schema 2 remain readable (46cccbd1).
• Freeze source files, supporting assets, pack dependencies, and effective
  configuration when publishing authored releases. Verify imported contents
  and reject conflicting or modified releases (46cccbd1).
• Export and import portable .efscenario and lifecycle .efpack archives.
  These archives carry authored content and dependencies; generated logs and
  checkpoints remain separate (46cccbd1).
• Expose lifecycle operations through the CLI, native chat skills, and Studio.
  Add optional display titles and a Properties interface for metadata, release
  history, lineage, and validation provenance (46cccbd1).
• Add reviewed scenario and pack deletion with dependency warnings and
  protections for active work. Preserve portable paths in deletion receipts
  (4555ee68, 46cccbd1, cf0afd1b).

Standalone macOS application

• Package Studio with a private Python runtime, the EvidenceForge engine,
  supporting resources, and native authoring skills. Using the packaged app
  does not require a separate Python installation (105f1478).
• Add backed-up Studio state upgrades and recovery, account isolation, and
  configurable retention and cleanup of installed runtimes
  (86d5f6f0, 77b2d51b).
• Preserve bundled pack identity across runtime upgrades and share the product
  version between Studio and its engine (7a8a0fb8, 17364e8f).

Release automation and fixes

• Build and attach the macOS DMG and SHA256 checksum automatically through
  GitHub Actions. Require release checks and installer verification before
  publishing the complete GitHub Release.
• Support numbered alpha, beta, and release-candidate versions. Prereleases
  can publish from annotated tags on dev while main retains the previous
  stable release (1b991359).
• Fix same-host deferred SSH process endpoint resolution and restore the
  portable pack archive inspection contract (5fc5d751, ab09dbcf).
• Improve platform-specific permission and Windows path tests, desktop
  presentation, and authoring-skill guidance
  (c0e5c5c3, 7bc56cea, 9072839b, 90ccbd80, 46849810).

Alpha availability and limitations

• The standalone installer targets Apple Silicon macOS. Intel macOS, Linux,
  and Windows installers are not included in this alpha.
• The macOS application is unsigned and has not been notarized.
• Codex must be installed separately to use Codex-assisted authoring.
• Studio GUI platform support is separate from existing engine/CLI support.
• Clean-machine installation and testing under separate OS accounts remain
  outstanding acceptance checks.

macOS installer

Apple Silicon only. Includes Python and the EvidenceForge runtime. Codex is installed separately for authoring. This build has no Developer ID signature or notarization. See docs/studio.md in the tagged source for installation and tested-platform limitations. Verify the download using the companion SHA256 file.
