The GitHub App token reached the agent's git commands through the origin
URL: after the clone fabro ran `git remote set-url origin` with the
token embedded, then tracked which generation the URL carried, held an
embed lease across every push so a refresh could not rewrite the URL
mid-operation, re-embedded on the first auth-shaped push failure in
case the agent had rewritten origin, and redacted the URL out of every
log line and output tail. The token showed in `git remote -v` and
`.git/config`.
The driver now installs ambient credentials for a checkout: one
credential-store line beside the checkout and a `credential.helper`
entry pointing at it, with the remote URL untouched. Fabro's part is
`credentials.rs`: the token source, one mint for the clone, one resolve
per push operation, and the facet call. The clone carries the token per
call and installs it afterwards; the ACP refresh tick rewrites the store
instead of the URL; fabro's own pushes pin one resolved token for the
whole operation and pass it per call, so nothing is ever re-embedded and
a retry after replication lag presents the same token by construction.
Gone with the URL: `push_credentials.rs`, `redact.rs`, the lease and
drift repair in `git_push`, `RefreshOutcome`, and the `credential_action`
and `refresh_error` fields on push attempt events. Stored events that
carry those keys still read. A failed store install after the clone now
fails setup, where a failed `set-url` used to be logged and repaired by
the first push. The one remaining caller of the URL redactor, the
server's repository probe, uses `DisplaySafeUrl::redact_in`.

- Add `additional_repositories` to the RunIntegrationsGithubSettings
OpenAPI schema and reuse the canonical Rust settings types through
`with_replacement`, with type-identity witnesses and JSON parity
tests for populated and empty repository sets.
- Regenerate the TypeScript API client.
- Document the feature in the GitHub integration and run-configuration
guides: exact layer replacement rules, single-token scope, gh/API
support, App-versus-PAT scope, the same-owner/same-installation
requirement, validation errors, supported Git URL forms, hard-failure
semantics for declared repositories, GH_TOKEN precedence, and the
security boundary (no second server-side repository intersection;
contents = "write" lets any stage push to any declared repository).
Correct the earlier claim that injecting GITHUB_TOKEN alone makes
arbitrary additional private clones work.
- Add a dated changelog entry and an opt-in live GitHub App e2e test
that verifies a scoped multi-repository token reads every declared
repository (and that a primary-only token cannot), with repositories
supplied through the test environment.

Fabro can mint a scoped sandbox GITHUB_TOKEN via
[run.integrations.github.permissions], but apps registered through the
manifest flow could not grant packages = "read" because the manifest
never requested it. Add Packages (read-only) so freshly registered apps
can download private GitHub Packages (for example npm registry
dependencies) inside sandboxes, mirroring how GitHub Actions workflows
use their built-in GITHUB_TOKEN for registry reads.
Existing apps still need the permission added manually in the app's
settings, as the docs already describe.

## 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.

## Summary
Token scopes describe what *a run* is authorized to do, not server
identity. Today they live under
`[server.integrations.github.permissions]`, which can't be overridden by
`workflow.toml` / `project.toml` (server keys are stripped from
per-workflow layers) — so projects and workflows can't tighten or relax
permissions despite the docs already advertising a per-run config. This
PR moves them under `[run.integrations.github.permissions]`, where the
standard layer-merge (workflow > project > user > defaults) Just Works.
Greenfield, no migration shim.
## What changed
- **New layer/resolved types** in `fabro-config` and `fabro-types`:
`RunIntegrationsLayer`, `RunIntegrationsGithubLayer`, and resolved
counterparts. `permissions` becomes a flat `HashMap<String,
InterpString>` post-resolve; empty = no token requested.
- **Server schema**: `permissions` removed from `GithubIntegrationLayer`
/ `GithubIntegrationSettings`. `deny_unknown_fields` rejects the stale
path.
- **Bundled `workflow.toml` parsing** (`run_manifest.rs`): now goes
through `SettingsLayer` via the new `parse_run_layer_from_settings_toml`
helper, so stale `[server.integrations.github.permissions]` errors
instead of being silently dropped by the old `toml::Table` lift-out.
- **Consumers updated**: server preflight, run launch path, and the CLI
worker (`runner.rs`) all read run-level permissions. CLI worker
previously hardcoded `HashMap::new()` — runs launched via the local CLI
path were getting no `GITHUB_TOKEN` regardless of TOML.
- **Shared helpers** on `RunIntegrationsGithubSettings`:
`is_token_requested()` and `resolve_permissions(lookup)` so server and
CLI don't drift.
- **OpenAPI + TS client** regenerated; new `RunIntegrationsSettings` /
`RunIntegrationsGithubSettings` schemas added, `permissions` removed
from `GithubIntegrationSettings`.
- **Repo workflows + docs** rewritten to the new path. Docs gain a
security-model note (boundary = installation grants; no Fabro-side cap).
## Key design decision: hand-rolled `Combine` for
`RunIntegrationsGithubLayer`
`ReplaceMap`'s "empty inherits from below" semantics (`maps.rs:76-80`)
are wrong here — we want `permissions = {}` in a higher layer to act as
an explicit clear. So the layer field is `Option<HashMap<...>>` with
hand-rolled `Combine`:
| Higher layer | Lower layer | Result |
|---|---|---|
| `None` | anything | lower (inherit) |
| `Some(map)` | anything | `Some(map)` (full replace, including
`Some({})` = clear) |
Not derived: the blanket `Option<T: Combine>` impl would recurse into
the inner `HashMap` and reintroduce empty-fallback. Documented inline in
`layers/run.rs`.
`InterpString` is preserved through resolve and only flattened to
`String` at the start-services boundary, matching the existing pattern.
### Plan Summary
- New `[run.integrations.github.permissions]` layer + resolved types;
remove from server side.
- Hand-rolled `Combine` so empty-wins-as-clear; no change to
`ReplaceMap` semantics for other consumers.
- Strict `SettingsLayer` parse for bundled `workflow.toml` so stale
schema errors loudly.
- Both server and CLI worker paths read run-level permissions via shared
helpers.
- OpenAPI + TS client regenerated; parity test added.
- Repo workflow TOMLs and `integrations/github.mdx` rewritten.

Invert the docs convention so the Mintlify-published site lives under
docs/public/ and internal artifacts (strategy docs, brainstorms, plans,
etc.) sit at docs/ root or docs/internal/. Tools that default to writing
into docs/ now land in the catch-all instead of leaking into the
published tree.
- Move Mintlify content (administration/, agents/, api-reference/,
changelog/, core-concepts/, examples/, execution/, getting-started/,
human-tools/, integrations/, languages/, reference/, tutorials/,
workflows/, images/, logo/, docs.json, favicon.svg, dot-highlight.js)
into docs/public/.
- Collapse docs-internal/ into docs/internal/.
- Update Rust path references (fabro-api/build.rs, fabro-server,
fabro-dev), TypeScript generator arg, CI path filters, clippy.toml
reasons, AGENTS.md/CLAUDE.md, and README.md image refs.
Mintlify dashboard project root must be updated to docs/public/ in a
follow-up. .mintignore move/trim and .claude/skills/ updates land in a
separate commit.
