 Each stage is executed by `OrchestratorAgent.executeStage()`. The orchestrator delegates intelligent stages (research, plan, execute, test, verify) to specialized agents via `context.backend` when available, falling back to mechanical execution when no backend is configured. Mechanical stages (specify, clarify, complete) are always handled by the orchestrator directly.

 **The git log IS the project memory.** Every decision, escalation, lesson learned, and verification result is encoded in commit messages using structured `---ci---` YAML blocks. An agent's first impulse to gather context is `git log`, not file reads. Another agent with access to only commit messages (no code, no diffs) can reconstruct the project state completely.

+## Intelligence Backends
+
+CIAgent supports 5 intelligence backends. Set the appropriate environment variable and use `--backend` to select:
+
+| Backend | Setup | Usage |
+|---------|-------|-------|
+| **OpenAI** | `export OPENAI_API_KEY=sk-...` | `ciagent run --backend openai` |

+| **Opencode** | `npm i -g opencode` | `ciagent run --backend opencode` |

+
+1. **Tier 1 — Mechanical**: Mines git history for uncovered requirements, repeated lessons, low-confidence decisions, escalation patterns, coverage gaps, architecture drift, and verification inversions
+2. **Tier 2 — Backend-enriched**: When a backend is available, prioritizes mechanical findings and suggests novel improvements
+3. **Tier 3 — Cross-project**: Mines patterns from other projects in the multi-project registry

 **Every merge to main creates a release. No exceptions.** Versioning follows a 3-tier model based on milestone type:

-### 3-Tier Versioning Model
+### Milestone Type and Versioning
+
+The milestone type is determined **before any development work** and governs all versioning for the entire milestone.
+
+**Define semver at milestone start:** establish the version and milestone type before writing code.
+
+Determine milestone type via `getMilestoneType()` which returns `"nfr" | "feature" | "major"`:

 | Milestone Type | Condition | Phase release | Milestone release |
 |---------------|-----------|---------------|-------------------|
-| **NFR** | All phases: fix/chore/docs/perf/refactor/test | Patch (`vX.Y.Z`) | None |
-| **Feature** | Any phase is `feat`, no schema break | Patch (`vX.Y.Z`) | Minor — `vX.(Y+1).0` |
-| **Schema-breaking** | Refactor/schema break/new direction | Minor — `vX.(Y+N).0` per phase | Major — `v(X+1).0.0` |
+| **NFR** | All phases are fix/chore/docs/perf/refactor/test | Patch — `v1.8.1`, `v1.8.2`, ... | None — final patch IS the deliverable |
+| **Feature** | At least one phase has new features (`feat`) | Patch — `v1.8.1`, `v1.8.2`, ... | Next minor — `v1.9.0` |
+| **Major** | Breaking schema changes or complete refactor | Minor — `v2.1.0`, `v2.2.0`, ... | Major — `v3.0.0` |

-**IMPORTANT:** Milestone tags are always the NEXT version, never the base:
- Feature: patches v0.5.1–v0.5.5 → milestone tag is v0.6.0 (NOT v0.5.0)
- Schema-breaking: minors v0.3.0, v0.4.0, v0.5.0 → milestone tag is v1.0.0
- NFR: no milestone tag — the milestone is implicit from the patch sequence
-
-Determine milestone type via `getMilestoneType()` which returns `"nfr" | "feature" | "schema-breaking"`.

+
+# CIAgent Ideate
+
+Run the CIAgent ideation engine to discover improvement opportunities based on git-native signals, codebase analysis, and cross-project patterns.
+
+**Usage:** `ciagent ideate [options]`
+
+## Step 0: Confirm Active Project
+
+Check `ci listProjects()` or read `.ciagent/config.json` to determine project context.
+
+If `.ciagent/config.json` has `active_projects` array with length > 0:
+- Use `--project <slug>` to target a specific project
+- Use `--project all` to run ideation across all active projects (deduplicate findings)
+- If no `--project` flag, use first project in `active_projects`
+
+If `.ciagent/config.json` has `active_project` string (legacy):
+- Use that project as the target
+- Backwards-compatible: if both `active_project` and `active_projects` exist, `active_projects` takes precedence
+
+## Step 1: Load Project Context
+
+```bash
+git log --max-count=50
+git branch -a
+```
+
+Read project reference files:
+- `.ciagent/PROJECT.md` — Vision, requirements, constraints, key decisions
+- `.ciagent/ROADMAP.md` — Phases, milestones, success criteria
+- `.ciagent/REQUIREMENTS.md` — REQ-IDs, status, traceability
+- `.ciagent/ARCHITECTURE.md` — Component boundaries, data flow
+- `.ciagent/config.json` — Ideation configuration, autonomy level
+
+## Step 2: Run Ideation Tiers
+
+Execute tiers in order. Each tier produces `Idea[]` objects. Ideas from all tiers are merged and deduplicated before presentation.
+
+### Tier 1: Mechanical Analysis (Always Available)
+
+No backend required. All signals come from git history, `.ciagent/` files, and filesystem.
+
+#### 2.1 Git-Native Pattern Mining
+
+```bash
+git log --all --grep="lessons:" --format="%B" -50
+git log --all --grep="decisions:" --format="%B" -50 -- "***confidence***0.*"
+git log --all --grep="escalation:" --format="%B" -50
+git log --all --grep="compound:" --format="%B" -50
+```
+
+Extract:
+- **Repeated lessons** — topics appearing > 1 time → systemic issue
+- **Low-confidence decisions** — confidence < 0.7 in `---ci---` blocks → improvement targets
+- **Escalation types** — each type identifies a process gap
+- **Compound solutions** — suggest generalizing patterns that were solved multiple times
+- **Partial requirements** — `requirements: partial: [REQ-XX]` in `---ci---` blocks
+
+#### 2.2 Coverage Gap Analysis
+
+- Parse REQUIREMENTS.md for `pending` and `in_progress` status requirements
+- Cross-reference with PLAN.md task completion
+- Identify requirements with no corresponding implementation tasks
+
+#### 2.3 Verification Layer Inversion
+
+For each verification layer, identify what's MISSING:
+
+- **Structural**: Files referenced but not created, stubs, TODOs, placeholder implementations
+- **Behavioral**: Test suites with < 80% coverage, missing test files for covered requirements
+- **Security**: No STRIDE analysis for modified components, missing input validation patterns
+- **Quality**: P1/P2 review findings unresolved, consistent style violations
+
+#### 2.4 Architectural Drift Detection
+
+- Parse ARCHITECTURE.md component tree
+- Compare against actual `src/` directory structure
+- Flag components documented but not implemented
+- Flag components implemented but not documented
+- Check import graph for unauthorized dependencies between components
+
+#### 2.5 Spec-Driven Improvement
+
+- Analyze REQUIREMENTS.md for ambiguous language ("should" vs "must", undefined terms)
+- Check for contradictions between requirements
+- Compare against common patterns for the project type (identified from package.json keywords)
+- Flag requirements with no verification criteria
+
+### Tier 2: Backend-Enriched Analysis (When LLM Available)
+
+Requires an intelligence backend (opencode, openai, anthropic, or ollama).
+
+#### 2.6 Prioritization and Ranking
+
+- Evaluate all mechanical findings for impact and feasibility
+- Rank ideas by: (1) number of signals corroborating, (2) severity of the gap, (3) ease of addressing
+
+#### 2.7 Novel Improvement Suggestions
+
+- Suggest improvements beyond pattern matching (e.g., "consider rate limiting" based on industry best practices, not just a repeated lesson)
+- Generate concrete action plans for each accepted idea
+- Identify bleeding-edge approaches relevant to the project's tech stack
+
+#### 2.8 Chaos Engineering Ideation
+
+- Generate failure scenarios: "What if the backend is unavailable?", "What if a requirement changes mid-implementation?", "What if test coverage drops below threshold?"
+- Map failure scenarios to code that would break
+- Suggest resilience improvements for each scenario
+
+### Tier 3: Cross-Project Pattern Transfer (When Multi-Project Registry Exists)
+
+#### 2.9 Cross-Project Mining
+
+For each project in `.ciagent/config.json` projects array:
+- Read that project's `---ci---` blocks for lessons, decisions, compound solutions
+- Find patterns relevant to the current project (same requirement area, same tech stack from package.json)
+- Suggest adaptations of lessons learned elsewhere
+- Calculate relevance score based on tech stack similarity
+
+## Step 3: Merge and DeduplicateIdeas
+
+Combine ideas from all tiers. Deduplicate by:
+- Same `title` strings → keep highest confidence version
+- Same `relatedReq` → merge into single idea with combined sources
+- Same `category` + overlapping domains → keep most specific
+
+Sort by confidence (descending), then by number of corroborating signals.
+
+## Step 4: Interactive Validation
+
+Present ideas one-at-a-time to the user:
+
+```
+═══ Recommendation N of M ═══
+
+Category: [CATEGORY] | Confidence: [0.XX] | Tier: [mechanical/backend-enriched/cross-project]
+Title: [idea title]
+Rationale: [idea rationale]
+Related Req: [REQ-ID or "new requirement"]
+Source: [source signal type]
+
+Actions:
+  1. Accept (add to next milestone as new requirement)
+  2. Skip
+  3. Modify (edit title/rationale before accepting)
+  4. Details (show full analysis including signal sources)
+```
+
+For each accepted idea:
+1. Generate `IDEATE-NN` requirement ID
+2. Prompt for milestone placement (append to existing or create new)
+3. Add to REQUIREMENTS.md with status `pending`
+4. Add to ROADMAP.md next milestone
+
+## Step 5: Update Long-Term Documents
+
+For each accepted idea:
+
+### REQUIREMENTS.md
+
+Add a new row in the appropriate milestone section:
+```
+| IDEATE-NN | [idea title] | [priority] | [phase] | pending |
+```
+
+### ROADMAP.md
+
+Add the idea to the next milestone's phase structure:
+- If next milestone has a matching phase category, append to that phase
+- If no matching phase, suggest a new phase
+
+### ARCHITECTURE.md
+
+If the idea involves architectural changes, note the component change needed.
+
+### PROJECT.md
+
+If the idea adds new requirements or key decisions, update accordingly.
+
+Commit all document updates:
+```
+decision(P##): ideation results — [N] accepted, [M] skipped
+```
+
+## Step 6: Ask-After-Validation Kickoff
+
+After all ideas have been validated:
+
+```
+Accepted: [N] recommendations
+Skipped: [M] recommendations
+
+Would you like to kick off the run workflow for these ideas? (y/n)
+```
+
+If yes: Start `ciagent run` with the updated project context. The `--ideate` flag is NOT needed because the ideas are already in ROADMAP.md and REQUIREMENTS.md — the standard pipeline will pick them up.
+
+If no: Output summary and exit.
+
+## Command Flags
+
+| Flag | Description |
+|------|-------------|
+| `--category <cats>` | Focus on specific categories: security,quality,architecture,coverage,improvement,spec,chaos (comma-separated) |
+| `--affected` | Cascade impact analysis: given current changes, what else needs updating |
+| `--spec` | Analyze specification completeness and ambiguity |
+| `--external` | Include external signals: npm audit, OSV advisories, dependency staleness |

+| `--project <slugs>` | Target project(s): slug, comma-separated, or `all` |
+| `--backend <provider>` | Override intelligence backend for enrichment tier |
+
+## Pipeline Integration
+
+When `ciagent run --ideate` is used, the IDEATE stage is inserted between RESEARCH and PLAN:
+
+```
+SPECIFY → CLARIFY → RESEARCH → IDEATE → PLAN → EXECUTE → TEST → VERIFY → COMPLETE

 # CIAgent Ship

 Ship a CIAgent phase or milestone. Every ship creates a release — no exceptions.

-**3-Tier Versioning Model:**
+**Usage:** `ciagent-ship [phase_number|milestone]`
+
+## Autopilot Rules
+
+These rules are **non-negotiable**. The ship workflow runs in full autopilot mode:
+
+- **Zero HITL** — no confirmation prompts, no approval gates, no requests for human input. The agent executes the entire release flow autonomously.
+- **No Shortcuts** — deep validation, testing, and merge checks must all run in full. The lack of HITL is not an excuse to skip steps.
+- **Notification Only** — status updates are informational, not requests for approval. Report outcomes, never ask permission.
+- **Autonomous Loop on Failure** — if any step fails (tests, pipeline, merge conflicts), iterate autonomously until success. Do NOT ask the user for guidance on how to fix a failing test or pipeline.
+- **Branch Hierarchy Enforced** — `main > milestone/vX.X-slug > phase/NN-slug`. Phase merges into milestone, milestone merges into main. This is validated, not assumed.
+
+## Milestone Type and Versioning
+
+The milestone type is determined **before any development work** and governs all versioning for the entire milestone.
+
+**Define semver at milestone start:** establish the version and milestone type before writing code.
+
+Determine milestone type by calling `getMilestoneType()` which returns `"nfr" | "feature" | "major"`:

 | Milestone Type | Condition | Phase release | Milestone release |
 |---------------|-----------|---------------|-------------------|
-| **NFR** | All phases: fix/chore/docs/perf/refactor/test | Patch (`vX.Y.Z`) | None |
-| **Feature** | Any phase is `feat`, no schema break | Patch (`vX.Y.Z`) | Minor — `vX.(Y+1).0` |
-| **Schema-breaking** | Refactor/schema break/new direction | Minor — `vX.(Y+N).0` per phase | Major — `v(X+1).0.0` |
+| **NFR** | All phases are fix/chore/docs/perf/refactor/test | Patch — `v1.8.1`, `v1.8.2`, ... | None — final patch IS the deliverable |
+| **Feature** | At least one phase has new features (`feat`) | Patch — `v1.8.1`, `v1.8.2`, ... | Next minor — `v1.9.0` |
+| **Major** | Breaking schema changes or complete refactor | Minor — `v2.1.0`, `v2.2.0`, ... | Major — `v3.0.0` |

-**CRITICAL:** Milestone tags are always the NEXT version, never the base:
- Feature: patches v0.5.1–v0.5.5 → milestone tag is v0.6.0 (NOT v0.5.0)
- Schema-breaking: minors v0.3.0, v0.4.0, v0.5.0 → milestone tag is v1.0.0

 | Milestone completion | NFR | Patch (last phase) | None | v0.1.3 (no milestone tag) |
 | Milestone completion | Feature | Last patch | Minor `vX.(Y+1).0` | v0.3.0 (NOT v0.2.0) |

+| Milestone completion | Major | Last minor | Major `v(X+1).0.0` | v1.0.0 |

 Phase number within the milestone determines the increment:
