Subject: [PATCH 1/8] Remove broken `bates start` subcommand

PR #31 added a `bates start` subcommand to the existing escript, but it
crashed immediately because escripts cannot carry `erlexec`'s
`priv/exec-port` C binary. The escript packaging format is the wrong
tool for the daemon.

This removes `Bates.CLI.Start`, the dispatcher clause that routed
`start` to it, the `bates start` line in the usage banner, and the
test file. The matching usage assertion in `Bates.CLITest` is updated.

A subsequent commit will reintroduce the daemon as a Mix release named
`batesd` so `erlexec`'s priv directory is available at runtime.

Subject: [PATCH 2/8] Update not-running messaging to point at `batesd`

The control commands previously told users to run `bates start` when
the daemon was unreachable. With `bates start` removed and the daemon
shipping as a Mix release named `batesd`, the diagnostic now reads
"Bates is not running. Start it with: batesd."

Also rewords `Bates.Prerequisites` and `Bates.CLI.Setup` docstrings to
describe the gates and setup work in terms of `batesd`.

Subject: [PATCH 3/8] Boot daemon prep from `Bates.Application.start/2`

Move the argv parser, config-path application, and prereq verifier
that the doomed `Bates.CLI.Start` owned into `Bates.Application.start/2`
so the same supervision tree boots correctly under both
`mix phx.server` and `bin/batesd` (the upcoming Mix release).

The work lives in a new `Bates.Daemon` module as three pure helpers
(`parse_argv/1`, `apply_options/1`, `verify_prerequisites/0`) so each
piece is unit-testable without trapping `System.halt/1`. `start/2`
itself is a thin orchestrator that halts with code 2 on parse or
prereq failures, matching what `bates start` used to do.

Tests run `Application.start/2` because `:bates` is a started
application. To keep them from tripping the prereq gate (or being
rejected by the argv parser, which sees `["test"]`), `config/test.exs`
sets `config :bates, skip_prereq_check: true`, and `start/2` short-
circuits the entire boot prep when that flag is set. The default of
`false` keeps the gate active in dev and in the release.

`Bates.Daemon` does NOT call `Mix.env/0` or any other build-time
module: `Mix` is unavailable in releases.

New `Bates.DaemonTest` covers `--config` parsing (default + override),
unknown-switch and unexpected-positional rejection, application of
the parsed `--config` to `:bates, :config_path`, and the prereq
diagnostic when `caddy` is off `$PATH`.

Subject: [PATCH 4/8] Add `batesd` Mix release configuration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Declare a `batesd` Mix release in `source/mix.exs`'s `releases:`
keyword. The release embeds ERTS, includes every dependency's `priv/`
directory, and starts `:bates` permanently — so `erlexec` finds its
`exec-port` C binary at runtime, which the escript packaging format
could not deliver.

`mix release` generates `bin/batesd` as a multi-subcommand dispatcher
(`start`, `daemon`, `remote`, `eval`, ...). A custom `:steps`
callback (`install_launcher/1`) renames that file to
`bin/batesd-orig` and writes a thin wrapper at `bin/batesd` that
always invokes the foreground `start` subcommand. Users see a single
command: `batesd [--config <path>]` — no subcommand maze.

The wrapper is written directly inside the `:steps` callback rather
than via `rel/overlays/`. Overlays are copied during `:assemble`,
which makes the rename-then-overlay sequence awkward; doing the
rename and the wrapper write in the same custom step keeps the
ordering obvious.

Add a minimal `config/prod.exs` so `MIX_ENV=prod mix release batesd`
can read environment-specific endpoint settings. The file mirrors
`dev.exs` for now (port and `secret_key_base`); follow-up work can
diverge as needed. `config/runtime.exs` is intentionally absent —
the release reads its only environment-dependent setting
(`--config <path>`) from argv inside `Bates.Application.start/2`.

Subject: [PATCH 5/8] Update specs for the two-binary topology

`specs/cli.md` removes the `### bates start` section and the option
table that came with it, points the not-running message at `batesd`,
points the configuration override description at `batesd`, and
rewords the "How It Connects" `bates start` bullet to describe
`batesd`. A new `## Daemon` section documents `batesd`'s flags,
prereq behavior, and intended invocation (foreground until the
launchd v2 proposal lands). The intro paragraph now describes the
two binaries explicitly.

`specs/system-overview.md`'s `### CLI` section now spells out the
two-binary topology: `batesd` is the server (Mix release, embeds
ERTS so `erlexec` finds its priv binary), and `bates` is a thin
client escript for the control commands.

-2. `/etc/resolver/test` exists (DNS resolution for `*.test`).

-If either check fails, prints a message pointing to `bates setup`
-and exits. Bates does not attempt to fix prerequisites automatically.
-Caddy's local CA root certificate trust is set up during `bates

covering both binaries: `mix escript.build` for the `bates` client
and `MIX_ENV=prod mix release batesd` for the daemon. Includes the
`--config` flag, the foreground/Ctrl-C semantics, and a couple of

+## Build and Run
+
+Bates ships two binaries: `batesd` (the server, a Mix release) and
+`bates` (a thin escript client for control commands). From `source/`:
+
+```bash
+mix deps.get
+mix escript.build               # produces source/bates (the CLI)
+MIX_ENV=prod mix release batesd # produces source/_build/prod/rel/batesd/
+```
+
+Run the daemon in the foreground:
+
+```bash
+_build/prod/rel/batesd/bin/batesd
+```
+
+Pass `--config <path>` to override the default config location
+(`~/.config/bates/config.toml`). Ctrl-C shuts the daemon down.
+
+The `bates` escript talks to the running daemon via the JSON API.
+With `bates` and `batesd` both on `$PATH`:
+
+```bash
+bates status
+bates env myapp

Subject: [PATCH 7/8] Pass `--config` to the release via `BATES_CONFIG_PATH`

The mix-release `start` subcommand discards extra argv, and the
generated `elixir` launcher's CLI mode interprets argv as
`[script | args]` (so passing `--config` directly would make it
treat the flag as a script filename). Have the `bin/batesd`
wrapper parse `--config` in shell and export it as the
`BATES_CONFIG_PATH` environment variable, then add
`Bates.Daemon.apply_env/1` to plumb that into
`:bates, :config_path`.

`Bates.Application.start/2` now runs the env step after argv so the
env var wins when both are set (the wrapper sets it deliberately;
the argv path stays for `mix phx.server`).

+## Execution Notes
+
+### Assumptions Confirmed
+
+- `MIX_ENV=prod mix release batesd` builds cleanly on this codebase (POC gap #1).
+- `mix test` passes with `skip_prereq_check: true` in `config/test.exs` even on a machine without `caddy` on `$PATH` (POC gap #4).
+
+### Deviations From Plan
+
+- **Phase 3 — `skip_prereq_check` gate widened.** The plan said the flag skips only the prereq check. In practice, `mix test` invokes `Bates.Application.start/2` with `System.argv() == ["test"]`, which the new daemon argv parser rejects as a stray positional. Gated the entire `boot_daemon` orchestrator (argv parse + apply + prereq) on the flag, not just the prereq step. Same intent (don't trip on dev machines), broader scope.
+- **Phase 3 — extracted `Bates.Daemon` module.** The plan said inline if `start/2` orchestration stays under three lines. The boot pipeline grew to four steps (`parse_argv` → `apply_options` → `apply_env` → `verify_prerequisites`); extracted into `Bates.Daemon` for testability. `start/2` stays a thin wrapper around `boot_daemon/0`.
+- **Phase 4 — overlay mechanism abandoned for direct write.** The plan preferred option 1 (custom `:steps` callback to rename the generated launcher, then drop an overlay at `bin/batesd`). Sandbox restrictions made the overlay's `chmod +x` impossible to commit. Switched to the documented fallback: do the rename + write + `File.chmod!` entirely inside the `install_launcher/1` callback. No `source/rel/overlays/` directory exists in the final tree.
+- **Phase 4 — added `config/prod.exs`.** Not in the plan. `config/config.exs` does `import_config "#{config_env()}.exs"` and the prod release fails to assemble without a `config/prod.exs`. Added a minimal stub mirroring `dev.exs` (Endpoint port 4080, secret_key_base, `:info` log level).
+- **Phase 4 — env-var path for `--config`.** Big surprise mid-Phase 4: `_build/prod/rel/batesd/bin/batesd --config /x` did not honor the flag. Two stacked problems: (1) the mix-release `start` subcommand discards extra argv at the shell level, and (2) the `elixir` launcher's CLI mode interprets argv as `[script | args]`, so even after patching `start)` to forward `"$@"`, `--config` got read as a script filename and `start_cli` halted. Solved by having `bin/batesd` parse `--config` in shell, export it as `BATES_CONFIG_PATH`, then `exec batesd-orig start` with no argv. Added `Bates.Daemon.apply_env/1` to plumb the env var into `:bates, :config_path`. The argv path stays for `mix phx.server`; the env path covers the release. When both are set the env wins (the wrapper sets it deliberately).
+
+### Gotchas Worth Documenting
+
+- **`Mix.env/0` is unavailable in releases.** Plan called this out; confirmed during execution. The `skip_prereq_check` Application env var is the right approach.
+- **Mix-release `start)` case discards argv.** Anyone trying to pass argv through the launcher will hit this. The env-var indirection is the cleanest workaround that doesn't require patching the upstream launcher template.
+- **The escript no longer boots the OTP application.** Earlier work (commit `aaeb43f`) flipped `app: nil` in `mix.exs`'s `escript:` config so `bates env` doesn't accidentally start Caddy. This is unrelated to this plan but worth noting for context: the daemon path is `batesd` only; the escript is purely a JSON API client (plus `bates setup`, which shells out).
