-## Project Overview
-
-`timmy-config` is a sidecar overlay repository for the Timmy ecosystem. It is **not** a Hermes-agent fork. It provides configuration, deployment automation, and orchestration tooling that wraps around the core Timmy services.
-
-The repo ships its own `GENOME.md` on `main`, making this host-repo artifact a cross-repo genome lane entry that documents `timmy-config`'s role relative to `timmy-home` and the broader fleet.
-
-Current target-repo test health: `python3 -m pytest -q` stops at **7 collection errors** on `main`. This is documented and tracked in upstream issue timmy-config #823.

-## Entry Points and Data Flow
-
-### `deploy.sh`
-Primary deployment entry point. Orchestrates the rollout of configuration and sidecar services.
-
-### `config.yaml`
-Central configuration surface. Feeds into orchestration and task scheduling.
-
-### `gitea_client.py`
-Gitea API client. Handles communication with the Forge for issue and PR operations.
-
-### `orchestration.py`
-Orchestration engine. Coordinates task execution and deployment workflows.
-
-### `tasks.py`
-Task definitions. Contains the concrete work units dispatched by the orchestrator.
-
-## Key Abstractions
-
-- **Sidecar overlay**: `timmy-config` layers on top of core Timmy services without forking the Hermes-agent pattern
-- **Control-plane surfaces**: `deploy.sh`, `config.yaml`, `gitea_client.py`, `orchestration.py`, `tasks.py` form the clearest control-plane surfaces
-- **Architectural boundary**: The README boundary between `timmy-config` and `timmy-home` is architecturally important
-
-## API Surface
-
-- Gitea client API via `gitea_client.py`
-- Task scheduling via `tasks.py`
-- Deployment automation via `deploy.sh` and playbooks
-
-## Test Coverage Gaps
-
-- **7 collection errors** on `main` prevent pytest from running any tests
-- Upstream issue timmy-config #823 filed to track broken pytest collection
-- `bin/`, `playbooks/`, and `training/` directories referenced but test coverage status unknown
-
-## Security Considerations
-
-- `config.yaml` likely contains deployment credentials and service endpoints
-- `gitea_client.py` handles API authentication tokens
-- Playbooks execute system-level changes; audit trail important
-
-## Performance Characteristics
-
-- Cron-driven or manually triggered deployment cycles
-- Lightweight Python sidecar; no heavy computation expected
-- Gitea API rate limits are the primary bottleneck
-
-## Cross-References
-
-- Host repo: `Timmy_Foundation/timmy-home`
-- Target repo: `Timmy_Foundation/timmy-config`
-- Upstream follow-up: timmy-config #823 (broken pytest collection)
-- Related genome: target repo ships its own `GENOME.md` on main
