+Each stage is executed by `OrchestratorAgent.executeStage()`. The orchestrator delegates intelligent stages (research, plan, execute, verify) to specialized agents via `context.backend` when available, falling back to mechanical execution when no backend is configured.

CI	fb3f1df13e	release(v0.4.0): purge learnship, migrate .planning→.ci, fix backends, add test coverage - Remove all learnship references: Decision.learnship_equivalent field, agent persona prompts, opencode.json permissions, test fixtures - Migrate verification layers from .planning/ to .ci/: structural checks .ci/ dir + ROADMAP.md, behavioral checks ROADMAP.md - Fix ollama-local: remove sync require+curl blocking, use async fetchAvailableModels() in callModel - Fix opencode.json: use __OPENCODE_DIR__ template tokens, remove legacy learnship permission entries - Remove duplicate install script from package.json (keep postinstall) - Fix quality any-regex false positives (target type annotations only) - Add backends test coverage: backends.test.ts, tool-registry.test.ts - Version bump 0.3.0 → 0.4.0 - Artifacts module: rename .planning→.ci internal paths - Remove dead TODO_PATTERN/FIXME_PATTERN constants ---ci--- phase: 3 milestone: v0.4 status: complete requirements: covered: [REQ-09, REQ-10, REQ-11, REQ-13, REQ-14, REQ-17] partial: [] decisions: - id: D-001 decision: purge all learnship references from codebase rationale: project is CI-only, learnship is no longer a dependency confidence: 0.99 category: scope alternatives: [keep for historical reference] - id: D-002 decision: migrate verification from .planning/ to .ci/ paths rationale: .planning/ is removed schema, all current state lives in .ci/ confidence: 0.95 category: architecture alternatives: [keep dual-path support] - id: D-003 decision: use __OPENCODE_DIR__ template tokens in opencode.json rationale: hardcoded ~ paths fail in containers and non-standard homes confidence: 0.90 category: implementation_approach alternatives: [keep tilde expansion] ---/ci---	2026-05-29 16:18:30 +00:00
CI	7a20784c87	fix: remove hardcoded /home/jchery paths, use __OPENCODE_DIR__ template token resolved at install time Command markdown files now use __OPENCODE_DIR__ placeholder instead of hardcoded user path. Both postinstall.js and install.sh perform template replacement when copying files to ~/.config/opencode/, making CI portable across any user/machine/container.	2026-05-29 16:08:46 +00:00
CI	940b85bfae	feat(backends): multi-backend intelligence layer — LLM + Agent backends, persona-loading agents, honest CLI commands Add IntelligenceBackend abstraction with two categories: - LLMBackend (OllamaLocal, OllamaCloud): CI runs tool loop, provides tools, constructs prompts - AgentBackend (Opencode): agent runs own tool loop, CI serializes request Refactor all 18 agents from hardcoded stubs to persona loaders that delegate to the active backend or fail honestly when no backend is available. Refactor OrchestratorAgent.executeStage() from monolithic switch to agent delegation via STAGE_AGENT_MAP for intelligent stages (research, plan, execute, verify), with mechanical stages (specify, clarify, complete) staying inline. Wire CLI commands with --backend flag and auto-detection (opencode → ollama-local → ollama-cloud). Harden rollback/ship with real git operations. No command returns fake success.	2026-05-29 15:58:34 +00:00
