## Summary
Separates Fabro server secrets into two explicit scopes: **bootstrap**
secrets that come from process env or `server.env`, and **optional
integration** secrets that come exclusively from the vault. This makes
secret resolution simple and predictable, and removes all `process env →
server.env` fallback paths for optional integrations such as GitHub App,
Slack, Daytona, Brave Search, and LLM provider keys.
## What changed
**New `ToolSecrets` struct in `fabro-agent`** — Brave Search API key is
now passed explicitly through `SessionOptions.tool_secrets` rather than
read from process env inside the tool. The standalone CLI reads the key
at the CLI boundary (with an explicit
`#[expect(clippy::disallowed_methods)]` annotation); the server will
read it from the vault. The error message changes from
`"BRAVE_SEARCH_API_KEY environment variable is not set"` to
`"BRAVE_SEARCH_API_KEY is not configured"`.
**`VaultCredentialSource::vault_only` constructor in `fabro-auth`** —
Adds a constructor that passes `|_| None` as the env lookup, ensuring
the server LLM credential source never resolves provider keys from
process env.
**GitHub App secrets move to vault in install flows** — Both the CLI
`fabro install github` path and the browser install finish handler now
write `GITHUB_APP_PRIVATE_KEY`, `GITHUB_APP_CLIENT_SECRET`, and
`GITHUB_APP_WEBHOOK_SECRET` to the vault instead of `server.env`.
Switching strategies removes stale secrets from the other strategy's
storage location. The `vault_set` field type changes from `Vec<(String,
String)>` to `Vec<VaultSecretWrite>` to carry per-secret type metadata
(file vs. token).
**`fabro-vault` gains a `fabro-static` dependency** — Needed so the
vault crate can reference canonical env-var names from the shared
registry without a cycle.
**`GH_TOKEN` fallback removed** — `GITHUB_TOKEN` is now read from the
vault only; the changelog and `server-configuration.mdx` note drops
mention of `GH_TOKEN` as an accepted fallback.
**Version bump** — Workspace crates promoted from `0.244.0-nightly.0` to
`0.244.0`.
**Docs** — Internal strategy doc, public admin docs (Docker, Railway,
server-configuration, security, troubleshooting), and integration docs
(GitHub, Slack, Daytona, Brave Search, LiteLLM, tools reference, models)
all updated to reflect vault-only optional secrets and direct users to
`fabro secret set` rather than process env or `server.env`.
### Plan Summary
- **Task 1** (secret registry) — not yet present in this diff;
classification lives in the places that consume it.
- **Task 3–6** (vault-only lookups for GitHub, Slack, Daytona, LLM) —
implemented via `vault_only` constructor, `tool_secrets` threading, and
install-path changes.
- **Task 7** (Brave Search explicit injection) — `ToolSecrets`,
`register_core_tools` wiring, CLI boundary read.
- **Task 8** (install persistence) — GitHub App secrets written to
vault; token strategy writes `GITHUB_TOKEN` to vault and clears app
vault keys; app strategy clears `GITHUB_TOKEN` vault key.
- **Task 9** (docs) — all public and internal docs updated.

Keep non-secret terminal color controls in the worker subprocess environment so inherited stdout logs use the same color decision as the foreground server.
Probe the Daytona API at install, `fabro secret set DAYTONA_API_KEY`,
and `fabro doctor` time to confirm the configured key carries the
snapshot/sandbox scopes Fabro needs. Operators now see a precise scope
error against the control plane instead of a generic sandbox-create
failure at first run.

Add configurable server log destinations with an environment override so containers can stream foreground server logs to stdout while local installs keep file logging by default. Validate configured log filters at load time and reject stdout logging for daemon mode.
Add fabro-static::EnvVars as the shared registry for fixed environment variable names and migrate env reads, clap env bindings, and subprocess/test allowlists to use it.
Add clippy bans for raw std::env lookup APIs so future dynamic env facades must be documented explicitly.
