v0.0.27

Highlights — the core-thinning release

v0.0.27 lands the core-thinning program: a leaner, more hackable core with feature surface moved into optional mods.

• Artifacts reworked to files-only storage with a pinned recent-artifacts index and created_by provenance; agents now record canonical artifacts as durable memory pointers (#155, #156).
• Loops hardened — machine-readable stage verdicts, a two-verdict gate + anti-thrash circuit-breaker that escalates to an honest blocked state (instead of a false "completed"), and restart-safe durability — plus the loops-API program (live view, headless start, custom definitions) and an SSE event stream (#149–#151, #158).
• Identity simplified to soul.md + backstory.md + a new persona context/*.md tier (#157).
• Extensible API — mods can now register HTTP routes, including public/auth-exempt ones for webhook receivers and callbacks (#152, #159).
• Slimmer core — MCP client engine moved into core (management toolkit optional), the REPL fullscreen TUI removed, and Channels + several toolkits dropped (#145–#148).

⚠️ Breaking changes

This release removes several features from core and relocates them to optional mods. If you rely on any of these, act before upgrading:

• Backstory generator removed from core (#157). /backstory and source-file ingestion now live in the optional mod. Restore them with composer require coquibot/coqui-toolkit-backstory (published on Packagist). See docs/PROFILES.md for the migration notes.
• Webhooks extracted to an optional mod (#152). Webhook receivers/management moved to the coquibot/coqui-toolkit-webhooks mod (which also introduced the API-feature extension point). Install it if you use webhooks.
• Phase-1 removals (#148): Channels, the Composer/Packagist toolkits, and background-task tooling were removed from core.
• REPL fullscreen TUI removed (#147). The portal remains; the fullscreen terminal UI is gone.
• MCP management toolkit is now optional (#145). The MCP client engine ships in core; enable the management toolkit explicitly if you need MCP administration.
