+# AGENTS.md — CI Project Guidelines
+
+## Build & Run Commands
+
+- **Build**: `npm run build` (compiles TypeScript to `dist/`)
+- **Typecheck**: `npm run typecheck` (runs `tsc --noEmit`)
+- **Test**: `npm run test` (runs Jest with ts-jest)
+- **Dev**: `npm run dev` (runs CLI via ts-node)
+
+## Project Overview
+
+CI (Continuous Intelligence) is a fully autonomous AI-driven software engineering harness. It receives a specification, resolves ambiguities through a single Clarify phase, then executes the full pipeline (research → plan → execute → verify) autonomously, escalating only when it cannot safely proceed alone.
+
+## Architecture

+
+## Key Design Decisions
+
+- **Autonomy levels**: `full` (no HITL after clarify), `supervised` (escalate on gates + verification failures), `guided` (escalate on every decision gate)
+- **Decision confidence thresholds**: High (>0.85) auto-decide and log; Medium (0.60–0.85) auto-decide with assumption logging; Low (<0.60) escalate to human
+- **Escalation timeout**: Default 5 minutes, then auto-proceeds with recommended option. Set to `0` to require human, `-1` to always auto-proceed
+- **18 agents** inherited from Learnship, all re-prompted for autonomous operation. OrchestratorAgent is CI-specific
+- **Git-native context**: The git log IS the project memory. Agent's first impulse to gather context is `git log` + `git branch`, not file reads. Dynamic state (decisions, escalations, lessons, compounding) lives in `---ci---` YAML blocks in commit messages. `.ci/` holds only long-lived reference docs (PROJECT.md, ARCHITECTURE.md, ROADMAP.md, REQUIREMENTS.md, config.json).
+- **Artifact compatibility**: CI no longer writes `.planning/` schema. Dynamic state is derived from git history. `.ci/` files follow a CI-native schema.
+
+## Code Conventions
+
+- **Language**: TypeScript with ES2022 target, Node16 modules
+- **Module resolution**: Node16 style with `.js` extensions in imports
+- **Agent pattern**: All agents extend `BaseAgent` with `name`, `description`, and `execute(context: AgentContext): Promise<AgentResult>`
+- **No runtime validation library**: Uses plain TypeScript types, not Zod schemas (Zod is a dependency but types are hand-defined)
+- **File I/O**: Use `src/utils/file.ts` helpers (`writeFile`, `readFile`, `ensureDir`, `readJSON`, `writeJSON`) instead of raw `fs` calls in agent/business logic
+- **Config**: `CIConfig` type and `DEFAULT_CI_CONFIG` in `src/types/config.ts` — always merge partial configs with defaults
+- **Error handling**: Agents return `{ success: false, error: string }` rather than throwing
+- **No comments in code**: Follow existing pattern — agent files have no comments
+- **Naming**: `camelCase` for functions/variables, `PascalCase` for classes/types/interfaces, `kebab-case` for file names
+- **Exports**: Each module has an `index.ts` barrel file re-exporting public API
+
+## Pipeline Flow
+
+```
+SPECIFY → CLARIFY → RESEARCH → PLAN → EXECUTE → VERIFY → COMPLETE
+```
+
+Each stage is executed by `OrchestratorAgent.executeStage()`. The orchestrator iterates through `STAGE_ORDER` and collects `PhaseResult` for each.
+
+## Agent Modification Rules (from PRD)
+
+| Agent | Key Modification |
+|---|---|
+| planner | Never set `autonomous: false`. Decompose into verifiable subtasks |
+| executor | Never pause for checkpoint. Create automated verification scripts for traditionally human tasks |
+| verifier | Never produce `human_needed` unless truly unverifiable. Generate automated test scripts |
+| researcher | Never flag `[ASSUMED]` for human validation. Log assumption to DECISIONS.md with confidence |
+| challenger | Binding verdicts. Only escalate when confidence < 0.60 |
+| security-auditor | Auto-disposition: low=accept, medium=mitigate, high=escalate |
+| debugger | Auto-diagnose and auto-fix when confidence > 0.60 |
+| code-reviewer | Auto-apply P0 fixes. Flag P1+ for post-hoc review |
+
+## Verification Layers
+
+1. **Structural**: Files exist, imports wired, no stubs/TODOs
+2. **Behavioral**: Generate and run automated tests for must-haves (currently stub)
+3. **Security**: STRIDE analysis with auto-disposition (currently stub)
+4. **Code Quality**: Multi-persona review with P0 auto-fix (currently stub)
+
+## Testing
+
+- Test framework: Jest with ts-jest
+- Test file pattern: `**/*.test.ts` in `src/`
+- Run: `npm run test`
+- 25 test suites, 218 tests covering types, core, git-native, verification, and utility modules
+- Tests use temp directories (os.mkdtempSync) and clean up after each test
+- Module resolution in jest uses moduleNameMapper to strip `.js` extensions
+
+## Important Files
+
+- `.ci/config.json` — Project-level CI configuration (autonomy, parallelization, verification, security, git)
+- `.ci/PROJECT.md` — Vision, core value, requirements, constraints, key decisions table
+- `.ci/ARCHITECTURE.md` — System architecture, component boundaries, data flow
+- `.ci/ROADMAP.md` — Phase breakdown, milestone mapping, success criteria, progress table
+- `.ci/REQUIREMENTS.md` — v1/v2 requirements with REQ-IDs and traceability matrix
+- Git log — Primary project memory: decisions, escalations, lessons, compounding, verification results
+- Branch structure — `phase/NN-slug` (active/complete) and `milestone/vX.X-slug` branches
+
+## Release Flow
+
+### Automation Requirements (Full Autopilot)
+
+- **Zero-HITL Execution**: Beyond initial milestone setup, operate fully autonomously. No confirmation, permission, or prompts to the user.
+- **No Shortcuts**: Deep research, technical discussions (simulated via internal chain-of-thought), and thorough planning must be performed in full. Autonomy does not bypass rigor.
+- **Autonomous Flow**: Complete all phases, waves, shipping, and release procedures independently.
+- **Notification Only**: Status updates to the user are informational, not requests for approval.
+- **Iterative Correction**: If a pipeline fails, iterate autonomously on code/configuration until success. Do not ask the user for guidance on fixing failures.
+
+### Execution Workflow
+
+1. **Pre-Development Setup**
+   - Define semver tag before any development work begins
+   - Ensure milestone is defined with version mapping: Major → Project, Minor → Milestone, Patch → Phase
+
+2. **Development & Integration**
+   - Create a dedicated feature branch in Gitea
+   - Create/configure the CI pipeline via coreci
+   - Create comprehensive tests to validate the feature
+   - Push all changes to the Gitea repository
+
+3. **PR & Quality Assurance**
+   - Open PR in Gitea
+   - Set PR to auto-merge upon pipeline success
+   - **Never merge a PR with a failed pipeline test**
+   - Conduct thorough autonomous review of the PR
+   - On success: approve, merge, notify user. On failure: iterate autonomously until pipeline passes
+
+4. **Release Finalization**
+   - Apply the previously defined semver tag in Gitea
+   - Create distribution packages via coreci
+   - Generate comprehensive release notes
+
+### Supported Ecosystem
+
+| Component | Provider | Detail |
+|---|---|---|
+| **VCS** | **Gitea** | https://git.cloudinit.dev |
+| **CI** | **coreci** | https://coreci.dev |
+| **CLI** | `tea` | Gitea CLI |
+
+> Gitea serves strictly as the VCS. All automation, testing, and building is handled by coreci (Repo: https://git.cloudinit.dev/cloudinit-dev/coreci).
+
+## Current State
+
+- **v0.2.0**: Git-native architecture — project memory lives in git log, not `.planning/` files
+- **New modules**: commit-parser (`---ci---` YAML block extraction/parsing), commit-builder (structured commit message generation), git-context (project state reconstruction from git log + branches), git-branch (phase/milestone branch lifecycle), ci-files (`.ci/` long-lived reference file management)
+- **Commit schema**: Every CI-generated commit contains a `---ci---` YAML block with phase, milestone, status, decisions, escalations, requirements, lessons, and compound metadata
+- **Branch strategy**: `phase/NN-slug` and `milestone/vX.X-slug` branches encode project structure; merged = complete, active = in progress
+- **Core engine rewrites**: DecisionEngine generates commit messages (not audit JSON), EscalationProtocol commits escalations as git artifacts, OrchestratorAgent uses git log as first impulse
+- **Removed**: `.ci/audit/` directory (audit trail is git log), `.planning/` directory (dynamic state derived from git history)
+- **`.ci/` contents**: `config.json`, `PROJECT.md`, `ARCHITECTURE.md`, `ROADMAP.md`, `REQUIREMENTS.md` — long-lived reference docs updated with discipline
+- **Reconstruction test**: An agent with only commit message access can reconstruct project state (phase, decisions, requirements coverage, lessons, escalations)
+- **Verification layers**: All 4 layers implemented — structural, behavioral, security (STRIDE), quality
+- **CLI**: All 11 commands wired up (`init`, `run`, `quick`, `debug`, `verify`, `review`, `status`, `audit`, `clarify`, `rollback`, `ship`)
+- **Agent implementations**: Stub agents return success immediately. Real LLM-based agent implementations are needed for research, planning, execution, verification, etc.
+- **Tests**: 25 test suites, 218 tests covering types, config, decision-engine, escalation, clarify, commit-parser, commit-builder, git-context, git-branch, ci-files, all 4 verification layers, file utils
