Chatobby Runtime 0.4.2

Chatobby Runtime 0.4.2 improves long-session continuity, skill and capability
discovery, memory maintenance, and safe Obsidian automation.

Context and compaction

• Mutable Project, permission, task, memory, runtime, channel, subagent, and
  Obsidian state now advances at the end of the conversation context, preserving
  a stable prompt prefix for providers that support prompt caching.
• Context compaction explicitly reconciles active skills, discovered
  capabilities, retained-result handles, work, decisions, requirements, and
  evidence before committing a checkpoint.
• Failed compaction preserves the original usable context and reports the last
  maintenance stage plus a bounded provider or validation cause.
• New unnamed sessions receive a concise title before their first normal
  response. Private bootstrap and checkpoint tools remain outside the feed,
  exports, permission settings, and ordinary tool discovery.

Skills, memory, and retrieval

• Native and managed skill loaders now identify their separate catalogues and
  guide the agent toward the other loader when a skill is requested from the
  wrong source.
• Capability search supports explicit domains and bounded exact, prefix,
  ranked, and fuzzy discovery without loading every specialist schema into the
  initial prompt.
• Memory search adds structured filters, typo-tolerant ranked pagination,
  bounded multi-record reads, and atomic revision-checked maintenance.
• Explicit follow-up commitments can be retained as typed obligations with
  revisioned completion evidence and current-policy enforcement.

Obsidian automation and safety

• Chatobby can discover a version-pinned Obsidian API catalogue and attach
  focused symbol guidance when an obsidian eval task needs it.
• Eval output is parsed as bounded structured JSON. Catastrophic operations are
  denied through the canonical permission gate without broadly blocking
  ordinary scripting.
• Obsidian application reload and restart require a fresh user decision, even
  under Full access or after an earlier generic CLI approval.
• An empty AGENTS.md now falls back to compatible CLAUDE.md guidance;
  non-empty AGENTS.md retains precedence.

Removed

The retired subagent-only Flows surface has been removed from the active
runtime tools, permissions, agent guidance, and native skills.

Alpha platform status

Windows remains the primary physically tested desktop path. Native macOS and
Linux packages remain best-effort experimental support pending a broader
physical-device acceptance matrix. macOS packages are ad-hoc signed and not
Apple-notarized; Linux packages initially target glibc desktop environments.
