The `server.integrations.slack.default_channel` field was typed
`Option<InterpString>` but was never documented as interpolable — every
doc example uses a plain channel name like `#releases`. It resolved only
env vars, only once at server startup, and that capability was inherited
from a uniform schema-staging design, not a deliberate feature. This
brings it in line with every other server-scope config field, which were
already demoted to plain literals under the project rule that
interpolation belongs to fields resolved with run context.
## What changed
- **Type** (`fabro-types`, `fabro-config` layers):
`Option<InterpString>` → `Option<String>` in `SlackIntegrationSettings`
and `SlackIntegrationLayer`.
- **Demotion warning** (`resolve/server.rs`): calls
`warn_if_demoted_template` at resolve time with the field path
`server.integrations.slack.default_channel`, matching the pattern used
for earlier server-field demotions. A value still containing a `{{ env.*
}}`-shaped token is stored verbatim and triggers a startup warning — no
resolution, no error.
- **Startup wiring** (`server.rs`): the `value.resolve(process_env_var)`
call and its error mapping are deleted; the literal string is passed
directly to `SlackService::new`, which already accepts `Option<String>`.
- **System status handler** (`handler/system.rs`): removed the
now-unnecessary `display_interp` helper that called `resolve_or_source`;
the field is cloned directly into the metadata map.
- **Wire shape**: unchanged. `InterpString` serialized as its raw source
string, so stored/wire JSON is identical before and after. The OpenAPI
spec is untouched.
## What is not changing
Per-run Slack channels — `run.notifications.<route>.slack.channel` and
`run.interviews.slack.channel` — remain `InterpString` with variable
substitution at run creation. Those are the intended interpolating
surface and are correct as-is.
## Migration signal
Anyone who placed a `{{ env.NAME }}` token in
`server.integrations.slack.default_channel` (only possible during ~3
months of nightly builds) will see a startup warning naming the field.
The value is treated as a literal; no data is lost and startup does not
fail.
## Interview-prompt routing observation (step 4)
The interview-prompt posting path checks `run.interviews.slack.channel`
first and falls back to the server default only when the run-scope field
is absent — the preference already exists. No routing change is needed
or made here.
