+This is a repo of onchain operational tasks. Active EVM tasks live under `active/evm/tasks/`; one task directory may contain configurations for multiple networks under `config/<network>/`.
+
+Active EVM task lifecycle:
+
+- A task directory represents one logical operation and carries its shared Makefile, scripts, and facilitator guide across network rollouts. Add another `config/<network>/` to the existing task instead of creating a duplicate task solely to change networks.
+- A task with multiple network configurations must require `TASK_NETWORK` on each `make` command line. Do not set a mutable default or rely on an exported environment value; use `make TASK_NETWORK=<network> <target>` so the selected network is visible at every invocation.
+- Keep the task-root `FACILITATOR.md` authoritative and network-agnostic, using explicit placeholders such as `TASK_NETWORK=<network>` and paths under `config/<network>/`. Per-network facilitator files are discouraged because they duplicate configuration and drift from the shared procedure. Only consider one as a last resort when a network has a materially different procedure that cannot be expressed in the root guide, `.env`, or signer README. If unavoidable, place only the procedural delta in `config/<network>/FACILITATOR.md` and link to it from the root guide.
+- Keep a task under `active/evm/tasks/` while any currently intended network rollout remains pending. Do not run `make archive-task` between network rollouts; archive only after every intended network configuration is executed or canceled and its final artifacts are committed.
+- Treat `archive/evm/` as historical. Do not edit or execute an archived task in place. If the same operation later needs another network rollout, restore the entire task directory to `active/evm/tasks/` before adding that network.
+- Store network-specific deployment address artifacts such as `addresses.json` under `config/<network>/`. Keep Forge broadcast records at task scope under `records/`; Foundry separates them by script and chain ID.

-Active EVM tasks live under `active/evm/`, which is a single shared Foundry
-project rather than a standalone project per task. A single `active/evm/Makefile`
-selects the active task via `TASK_ID` / `TASK_NETWORK`, reusable operation
-scripts are shared across tasks under `script/common/<category>/`, and each task
-directory holds only its own config, docs, and (per-network) validations and
-signatures:
+Active EVM tasks share the Foundry project under `active/evm/`, while each task owns its Makefile, facilitator guide, network configurations, signatures, and execution records. Reusable operation scripts live under `script/common/<category>/`; one-off scripts stay with their task.

-Task commands run from `active/evm`, selecting the task by `TASK_ID` /
-`TASK_NETWORK` (both default to the current task in the shared `Makefile`), e.g.
-`TASK_ID=<task> TASK_NETWORK=<network> make gen-validation-cb`. The shared
-Makefile runs Forge from `active/evm` using the shared `foundry.toml` and `lib/`,
-while task-specific files are read from `tasks/<task-id>/config/<network>/`.
-Reusable scripts are documented in [`active/evm/script/common/README.md`](active/evm/script/common/README.md);
-put a script under `script/common/<category>/` when it will be reused across
-tasks, and keep one-off task glue out of `common/`.
-
-The shared `active/evm/Makefile` selects a task (via `TASK_ID` / `TASK_NETWORK`)
-and sources that task's `.env` for `BASE_CONTRACTS_COMMIT`. To install
-dependencies for the shared project without selecting a task (e.g. to build the
-common scripts locally), invoke the root Makefile directly with a `PROJECT_DIR`
-override and an explicit `BASE_CONTRACTS_COMMIT`:
+Run task commands from `active/evm/tasks/<task-id>/`. A task with multiple network configurations must require `TASK_NETWORK` on each Make command line, for example `make TASK_NETWORK=sepolia gen-validation-cb`; it must not rely on a mutable default or exported environment value.

Per-network facilitator files are discouraged; if one is unavoidable for a materially different procedure, put only that procedural delta in `config/<network>/FACILITATOR.md` and link to it from the root guide.

+One task directory represents one logical operation across its intended network rollouts.

 ## Adding Scripts
 
-Use exact Solidity pragmas based on the contracts the script imports; preserve a script's original exact pragma when moving it here. Load config from environment variables into immutable variables where possible. Keep task-specific values in `tasks/<task-id>/config/<network>/.env`, `tasks/<task-id>/config/<network>/network.env`, or task-local JSON files rather than hardcoding them in common scripts.
+Use exact Solidity pragmas based on the contracts they import; preserve a script's original exact pragma when moving it here.

Keep scalar task-specific values in `tasks/<task-id>/config/<network>/.env`, or use the script-documented JSON input when structured data is required, rather than hardcoding values in common scripts.
+
+Network-specific deployment address artifacts belong under `tasks/<task-id>/config/<network>/addresses.json`. Common verifier scripts must require `ADDRESSES_JSON` explicitly instead of defaulting to the shared project or task root. Forge broadcast records remain at task scope because Foundry separates them by script and chain ID.
 
 If a script needs task-specific behavior, prefer a small task-local wrapper or Makefile target that passes environment variables into a common script. Move the underlying Solidity into this directory only when the operation itself is reusable.
