+# Ralph History
+
+## Iteration 0
+
+- Initialized worktree `feature/gitea-runtime-control-plane`
+- Wrote approved design spec and implementation plan
+- Created Ralph loop contract and task list
+- Verification: not started yet
+
+## Iteration 1
+
+- Goal: complete Task 1 package scaffold, spec loader, and sample workflow
+- Changed files:
+  - `pyproject.toml`
+  - `engine/devops_agent/__init__.py`
+  - `engine/devops_agent/cli.py`
+  - `engine/devops_agent/spec.py`
+  - `workflows/gitea-issue-delivery.md`
+  - `tests/unit/test_smoke_imports.py`
+  - `tests/unit/test_spec_loader.py`
+  - `tests/fixtures/specs/valid_workflow.md`
+  - `tests/fixtures/specs/invalid_missing_provider.md`
+  - `.gitignore`
+- Verification:
+  - `python -m pytest tests/unit/test_smoke_imports.py tests/unit/test_spec_loader.py -q`
+  - Result: `4 passed`
+- Blockers:
+  - Pytest tmp and cache facilities are unreliable in this Windows sandbox path, so tests must avoid `tmp_path` and rely on stable fixture files or repo-local paths.
+
+## Iteration 2
+
+- Goal: complete Task 2 compiler, validator, and policy enforcement
+- Changed files:
+  - `engine/devops_agent/compiler.py`
+  - `engine/devops_agent/validator.py`
+  - `engine/devops_agent/policies.py`
+  - `engine/devops_agent/spec.py`

+  - `tests/unit/test_policies.py`
+  - `tests/fixtures/specs/no_safe_outputs_for_write.md`
+  - `tests/fixtures/specs/invalid_path_scope.md`
+- Verification:
+  - `python -m pytest tests/unit/test_smoke_imports.py tests/unit/test_spec_loader.py tests/unit/test_compiler.py tests/unit/test_validator.py tests/unit/test_policies.py -q`
+  - Result: `11 passed`
+- Blockers:
+  - PyYAML treats `on` as a boolean in default parsing, so the spec loader now normalizes that key explicitly.
+
+## Iteration 3
+
+- Goal: complete Task 3 provider layer, Gitea provider, runtime, and evidence persistence
+- Changed files:
+  - `engine/devops_agent/evidence.py`
+  - `engine/devops_agent/runtime.py`
+  - `engine/devops_agent/providers/__init__.py`
+  - `engine/devops_agent/providers/base.py`

+  - `tests/integration/test_runtime_flow.py`
+  - `tests/fixtures/gitea/issue.json`
+  - `tests/fixtures/gitea/comment_event.json`
+- Verification:
+  - `python -m pytest tests/unit tests/integration -q`
+  - Result: `15 passed`
+- Blockers:
+  - None in code shape. Real Gitea acceptance still depends on environment credentials.
+
+## Iteration 4
+
+- Goal: complete Task 4 CLI, acceptance tests, and documentation updates
+- Changed files:
+  - `engine/devops_agent/cli.py`
+  - `tests/unit/test_cli.py`
+  - `tests/acceptance/test_gitea_acceptance.py`
+  - `README.md`
+  - `skills/gitea-issue-devops-agent/SKILL.md`
+  - `workflows/gitea-issue-delivery.lock.json`

+  - `python -m engine.devops_agent.cli validate workflows/gitea-issue-delivery.md`
+  - Result: `18 passed, 1 skipped`
+- Blockers:
+  - Real Gitea acceptance is blocked until `GITEA_BASE_URL`, `GITEA_REPO`, `GITEA_TOKEN`, and `GITEA_ISSUE_NUMBER` are provided.
+
+## Iteration 5
+
+- Goal: complete Task 5 full verification and real Gitea acceptance handoff
+- Verification:
+  - `python -m pytest tests/unit tests/integration tests/acceptance -q`
+  - `python -m engine.devops_agent.cli compile workflows/gitea-issue-delivery.md --output workflows/gitea-issue-delivery.lock.json`

+# Ralph Loop Plan
+
+## Goal
+
+Integrate a Gitea-backed agentic workflow runtime into this repository so the product moves from skill-only guidance to a real execution control plane. Deliver a repo-local workflow spec format, compiler, validator, runtime, Gitea provider, safe-output policy enforcement, evidence persistence, automated tests, and one real Gitea acceptance path.
+
+## Acceptance Criteria
+
+1. `workflows/gitea-issue-delivery.md` compiles into a lock artifact.
+2. Invalid workflow specs fail validation with explicit errors.
+3. Runtime refuses undeclared write actions and records evidence for allowed ones.
+4. Automated unit and integration tests pass.
+5. Real Gitea acceptance can read the selected issue and publish an evidence comment when credentials are present.
+6. README and `skills/gitea-issue-devops-agent/SKILL.md` reflect the new runtime model.
+
+## Verification Commands
+
+- `python -m pytest tests/unit tests/integration -q`
+- `python -m pytest tests/acceptance/test_gitea_acceptance.py -q`
+- `python -m engine.devops_agent.cli compile workflows/gitea-issue-delivery.md --output workflows/gitea-issue-delivery.lock.json`
+- `python -m engine.devops_agent.cli validate workflows/gitea-issue-delivery.md`
+- `git diff --check`

+# Gitea Agentic Runtime Implementation Plan
+
+> **For agentic workers:** REQUIRED: Use superpowers:subagent-driven-development (if subagents available) or superpowers:executing-plans to implement this plan. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build a Gitea-backed workflow spec/compiler/runtime subsystem that turns the existing delivery skill into a policy-enforced execution engine with automated tests and real Gitea acceptance.
+
+**Architecture:** Add a small Python control-plane package under `engine/devops_agent`, keep provider logic isolated behind interfaces, compile workflow specs into JSON lock artifacts, and run policy-guarded issue workflows against Gitea. Persist plans and evidence locally so tests and operators can inspect every run deterministically.
+
+**Tech Stack:** Python 3.11+, pytest, requests-free stdlib HTTP where practical, Markdown/JSON workflow artifacts, existing repository docs and Gitea workflow templates

+# Gitea Agentic Runtime Design
+
+**Date:** 2026-03-13  
+**Status:** Approved for implementation  
+**Scope:** Gitea single-platform real acceptance, with provider boundaries that keep later GitHub support incremental instead of invasive.
+
+## Goal
+
+Upgrade `gitea-issue-devops-agent` from a documentation-heavy delivery skill into a controlled execution subsystem that can:
+
+- parse repository-local workflow specs
+- compile and validate those specs into a locked execution plan
+- run a Gitea-triggered issue workflow under hard policies
+- persist plan and evidence artifacts
+- pass automated unit, integration, and real Gitea acceptance checks
+
+The external workflow remains:
+
+`Issue -> Plan -> Branch -> Draft PR -> Preview -> Test Loop -> Human Merge`
+
+The internal workflow gains a deterministic control plane.
+
+## Why This Design
+
+The repository currently has strong delivery guidance, but not a runtime that enforces it. `gh-aw` demonstrates the value of turning natural-language workflow definitions into constrained executable automations. We do not want to clone GitHub-native product shape. We do want equivalent execution discipline:
+
+- a spec format users can author
+- a compiler/validator that rejects unsafe or incomplete workflows
+- a provider layer for platform APIs
+- hard policy checks before write actions
+- run evidence suitable for audit and acceptance
+
+This keeps the product positioned as an enterprise AI DevOps control layer, not a GitHub Actions clone.
+
+## In Scope
+
+- Gitea provider
+- workflow spec parsing
+- compilation into lock artifacts
+- validation of triggers, permissions, safe outputs, edit scope, and evidence contract
+- runtime execution for selected issue flows
+- safe output enforcement for Gitea writes
+- evidence persistence
+- CLI entrypoints for compile, validate, run, and acceptance
+- automated tests
+- one real Gitea acceptance path
+
+## Out of Scope
+
+- GitHub provider implementation
+- autonomous queue-wide issue fixing
+- automatic merge
+- hosted webhook service
+- UI control plane
+- inference cost dashboards
+
+## Architecture
+
+### 1. Workflow Spec
+
+Workflow specs live in-repo and use frontmatter plus Markdown body:
+
+- frontmatter defines triggers, provider, permissions, safe outputs, required evidence, and policy defaults
+- body captures workflow intent, operator notes, and execution hints
+
+The spec is the source of truth. Runtime behavior never depends on free-form Markdown alone.
+
+### 2. Compiler
+
+The compiler loads a workflow spec and emits a lock artifact:
+
+- normalizes defaults
+- expands trigger shorthand into explicit configuration
+- resolves safe output declarations into executable policy objects
+- records required evidence and path scope
+
+The lock artifact is immutable input to runtime. It is designed as JSON in this iteration because JSON is easy to diff, assert in tests, and consume from Python.
+
+### 3. Validator
+
+Validation rejects unsafe or incomplete specs before runtime:
+
+- unsupported trigger combinations
+- missing provider
+- unsafe write permissions
+- missing safe outputs for write behaviors
+- invalid path scope syntax
+- missing evidence requirements
+
+This is the first hard boundary between intent and execution.
+
+### 4. Runtime
+
+Runtime consumes:
+
+- a compiled lock artifact
+- an event payload
+- provider configuration and credentials
+
+Runtime responsibilities:
+
+- load and sanitize issue-trigger context
+- initialize or update the persisted plan state
+- enforce policy gates before any write action
+- call provider APIs through a narrow interface
+- collect evidence and write run artifacts
+
+The runtime is not a general autonomous coding engine in this iteration. It is a control and orchestration layer for issue delivery actions.
+
+### 5. Provider Layer
+
+Provider interfaces isolate platform behavior from workflow logic.
+
+The first provider is `GiteaProvider`, which supports:
+
+- repository metadata reads
+- issue reads
+- issue comments
+- branch hint extraction inputs
+- draft PR preparation primitives
+
+The abstraction must make later `GitHubProvider` addition additive rather than structural.
+
+### 6. Policy and Safe Outputs
+
+The policy layer turns delivery rules into code:
+
+- read-only by default
+- no merge action
+- comment/create/update operations only if declared in safe outputs
+- path-scope enforcement for file writes
+- evidence-required status promotion
+- bounded output counts where relevant
+
+This is the key product maturity improvement over pure skill text.
+
+### 7. Evidence Layer
+
+Every run produces durable artifacts:
+
+- resolved plan state
+- execution summary
+- provider operations executed
+- evidence bundle for commit/PR/test/preview placeholders
+- acceptance result metadata
+
+Evidence is stored locally under a deterministic run directory so tests and operators can inspect it.
+
+## File Structure
+
+New code will be added under:
+
+- `pyproject.toml`
+- `engine/devops_agent/__init__.py`
+- `engine/devops_agent/spec.py`
+- `engine/devops_agent/compiler.py`
+- `engine/devops_agent/validator.py`

+Existing scripts will remain, but runtime may call them or share logic conceptually:
+
+- `skills/gitea-issue-devops-agent/scripts/issue_audit.py`
+- `skills/gitea-issue-devops-agent/scripts/change_scope.py`
+- `skills/gitea-issue-devops-agent/scripts/preview_slot_allocator.py`
+
+## Data Model
+
+### Workflow Spec
+
+Core fields:
+
+- `name`
+- `provider`
+- `on`
+- `permissions`
+- `safe_outputs`
+- `plan`
+- `policy`
+- `evidence`
+- `body`
+
+### Lock Artifact
+
+Core fields:
+
+- `version`
+- `compiled_at`
+- `source`
+- `provider`
+- `triggers`
+- `policy`
+- `safe_outputs`
+- `required_evidence`
+- `plan_defaults`
+- `instructions`
+
+### Run Artifact
+
+Core fields:
+
+- `run_id`
+- `workflow_name`
+- `provider`
+- `event`
+- `plan_state`
+- `operations`
+- `evidence`
+- `result`
+
+## Test Strategy
+
+### Unit Tests
+
+Verify:
+
+- frontmatter parsing
+- default normalization
+- validator failures and successes
+- policy enforcement
+- provider request shaping
+
+### Integration Tests
+
+Verify:
+
+- spec to lock compilation
+- lock to runtime execution
+- runtime interaction with a fake Gitea transport
+- evidence persistence
+
+### Acceptance Tests
+
+Verify against a real Gitea repo using env vars:
+
+- workflow compile and validate pass
+- runtime can load a selected issue
+- runtime can publish an evidence comment
+- acceptance artifacts are produced locally
+
+If env vars are absent, the acceptance suite must skip cleanly instead of failing misleadingly.
+
+## Acceptance Criteria
+
+This design is complete only when:
+
+1. A repo-local Gitea workflow spec compiles into a lock artifact.
+2. Invalid specs fail validation with clear messages.
+3. Runtime enforces safe outputs and refuses undeclared writes.
+4. Gitea real acceptance can read an issue and publish an evidence comment.
+5. Automated unit and integration tests pass.
+6. README and skill docs describe the new execution model and CLI usage.
+
+## Rollout Notes
+
+- Gitea is the first real provider.
+- GitHub support is intentionally deferred, but the provider interface must be stable enough to add later.
+- `jj` remains an internal reliability layer. This subsystem must not require `jj` for external usage.

 - Start coding only from a selected issue, not from an unbounded issue queue, unless the user explicitly asks for triage-only queue scanning.
 - Every delivery issue must have a persisted plan before any code changes.
+- Treat workflow spec, compiled lock artifact, and evidence artifacts as executable system-of-record once the runtime is available; do not rely on prose-only guidance for enforcement.
 - External collaboration stays Git-native: issue, branch, PR, pipeline, review app, merge.
 - AI output is provisional until tests, smoke paths, and review evidence exist.
 - Engineers stay in the loop from the initial PR onward and own white-box review.
 - Keep one active issue per branch and per execution agent unless the user explicitly approves batching.
 
+## Runtime Contract (Required)
+
+When the repository contains the runtime package, use it instead of ad-hoc execution:
+
+1. Author or update the workflow spec in `workflows/*.md`.
+2. Compile before execution:
+   - `python -m engine.devops_agent.cli compile workflows/gitea-issue-delivery.md --output workflows/gitea-issue-delivery.lock.json`
+3. Validate before execution:
+   - `python -m engine.devops_agent.cli validate workflows/gitea-issue-delivery.md`
+4. Run or accept only through declared safe outputs.
+5. Persist run evidence under `.tmp/...` and treat `run-artifact.json` as execution proof.
+6. For real Gitea verification, use:
+   - `python -m engine.devops_agent.cli acceptance workflows/gitea-issue-delivery.md --base-url <url> --repo <owner/repo> --token <token> --issue-number <n> --output-dir .tmp/acceptance/gitea`
+
+Hard rules:
+
+- No undeclared write actions.
+- No execution after failed validation.
+- No claiming completion without runtime evidence.

 - `scripts/issue_audit.py`: collect issues/comments/attachments, detect duplicates, score quality, detect unresolved/closed-open links, extract issue branch hints, and generate reports.
   - image intake uses three sources: markdown/html links, payload `assets/attachments` fields, and `/issues/*/assets` API endpoints.
   - if your Gitea blocks the assets endpoints, pass `--skip-asset-endpoints` and rely on payload extraction.
