Steps use checkbox (`- [ ]`) syntax for tracking.\n\n**Goal:** Make Fabro server secret resolution simple and predictable: bootstrap secrets come only from process env or `server.env`; optional integration secrets come only from the vault.\n\n**Architecture:** Introduce a small shared registry that classifies well-known secret names as bootstrap or optional. Keep `ServerSecrets` focused on bootstrap startup/runtime requirements, add vault-only helpers for optional integrations, and wire install mode so it can write optional secrets before enabling features such as GitHub auth.\n\n**Tech Stack:** Rust workspace crates (`fabro-static`, `fabro-auth`, `fabro-agent`, `fabro-server`, `fabro-cli`), existing vault storage, existing install persistence, existing docs under `docs/internal` and `docs/public`.\n\n---\n\n## Decisions Locked In\n\n- `server.env` is only for bootstrap/runtime secrets that the server may need before the vault can be used.\n- Process env is also bootstrap-only for server runtime. Optional server integrations do not read process env.\n- Vault is the only server/runtime source for optional integration secrets.\n- Optional secrets may be workflow-visible for now.\n- No compatibility shims or fallback aliases are required. Remove server-runtime `GH_TOKEN` fallback and optional `server.env` fallbacks.\n- Non-secret configuration, such as base URLs, org IDs, or catalog settings, remains configuration. This plan only governs secrets.\n- CLI/library code may still use env-backed credential sources where explicitly selected outside server runtime. The server runtime must not use that path for optional integrations.\n\n## Secret Model\n\nBootstrap secrets:\n\n- `SESSION_SECRET`\n- `FABRO_DEV_TOKEN`\n- object-store/storage credentials resolved by current server object-store builders, including manual AWS credentials such as `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, and `AWS_SESSION_TOKEN`\n\nOptional vault secrets:\n\n- LLM provider API keys and OAuth credential records\n- `FABRO_SLACK_BOT_TOKEN`\n- `FABRO_SLACK_APP_TOKEN`\n- `DAYTONA_API_KEY`\n- `BRAVE_SEARCH_API_KEY`\n- `GITHUB_TOKEN`\n- `GITHUB_APP_PRIVATE_KEY`\n- `GITHUB_APP_CLIENT_SECRET`\n- `GITHUB_APP_WEBHOOK_SECRET`\n\n## Change Map\n\n- Create `lib/crates/fabro-static/src/secret_registry.rs` for shared classification.\n- Modify `lib/crates/fabro-static/src/lib.rs` to export the registry.\n- Modify `lib/crates/fabro-server/src/server_secrets.rs` to make the bootstrap boundary explicit in tests and naming.\n- Modify `lib/crates/fabro-server/src/server.rs`, `diagnostics.rs`, `run_files.rs`, `run_manifest.rs`, `web_auth.rs`, `github_webhooks.rs`, and server handlers under `server/handler/` to use vault-only optional lookup.\n- Modify `lib/crates/fabro-server/src/startup.rs`, `serve.rs`, and `jwt_auth.rs` so GitHub auth validates `GITHUB_APP_CLIENT_SECRET` from vault while session/dev-token auth still validates bootstrap secrets.\n- Modify `lib/crates/fabro-auth/src/vault_source.rs` to expose an explicit vault-only credential source constructor for server runtime.\n- Modify `lib/crates/fabro-agent/src/config.rs` and `tools.rs` so `web_search` receives `BRAVE_SEARCH_API_KEY` explicitly instead of reading process env inside the tool.\n- Modify install flows in `lib/crates/fabro-server/src/install.rs` and `lib/crates/fabro-cli/src/commands/install.rs` so GitHub App secrets are written to vault, not `server.env`.\n- Modify `lib/crates/fabro-server/src/server/handler/secrets.rs` so bootstrap secrets cannot be written through the vault API.\n- Update public and internal docs after behavior is implemented.\n\n---\n\n## Task 1: Add The Shared Secret Registry\n\n**Files:**\n\n- Create: `lib/crates/fabro-static/src/secret_registry.rs`\n- Modify: `lib/crates/fabro-static/src/lib.rs`\n- Test: unit tests in `secret_registry.rs`\n\n- [ ] **Step 1: Define the registry types and classified names**\n\nCreate `secret_registry.rs` with this shape:\n\n```rust\nuse crate::EnvVars;\n\n#[derive(Clone, Copy, Debug, PartialEq, Eq)]\npub enum SecretScope {\n Bootstrap,\n OptionalVault,\n}\n\nconst BOOTSTRAP_SECRETS: &[&str] = &[\n EnvVars::SESSION_SECRET,\n EnvVars::FABRO_DEV_TOKEN,\n EnvVars::AWS_ACCESS_KEY_ID,\n EnvVars::AWS_SECRET_ACCESS_KEY,\n EnvVars::AWS_SESSION_TOKEN,\n];\n\nconst OPTIONAL_VAULT_SECRETS: &[&str] = &[\n EnvVars::ANTHROPIC_API_KEY,\n EnvVars::BRAVE_SEARCH_API_KEY,\n EnvVars::FABRO_SLACK_APP_TOKEN,\n EnvVars::FABRO_SLACK_BOT_TOKEN,\n EnvVars::GEMINI_API_KEY,\n EnvVars::GITHUB_APP_CLIENT_SECRET,\n EnvVars::GITHUB_APP_PRIVATE_KEY,\n EnvVars::GITHUB_APP_WEBHOOK_SECRET,\n EnvVars::GITHUB_TOKEN,\n EnvVars::INCEPTION_API_KEY,\n EnvVars::KIMI_API_KEY,\n EnvVars::MINIMAX_API_KEY,\n EnvVars::OPENAI_API_KEY,\n EnvVars::ZAI_API_KEY,\n EnvVars::DAYTONA_API_KEY,\n];\n\npub fn secret_scope(name: &str) -> Option {\n if BOOTSTRAP_SECRETS.contains(&name) {\n Some(SecretScope::Bootstrap)\n } else if OPTIONAL_VAULT_SECRETS.contains(&name) {\n Some(SecretScope::OptionalVault)\n } else {\n None\n }\n}\n\npub fn is_bootstrap_secret(name: &str) -> bool {\n secret_scope(name) == Some(SecretScope::Bootstrap)\n}\n\npub fn is_optional_vault_secret(name: &str) -> bool {\n secret_scope(name) == Some(SecretScope::OptionalVault)\n}\n```\n\n- [ ] **Step 2: Export the registry**\n\nModify `lib.rs`:\n\n```rust\nmod env_vars;\nmod secret_registry;\n\npub use env_vars::EnvVars;\npub use secret_registry::{\n SecretScope, is_bootstrap_secret, is_optional_vault_secret, secret_scope,\n};\n```\n\n- [ ] **Step 3: Add registry tests**\n\nAdd tests proving:\n\n- `SESSION_SECRET` and `FABRO_DEV_TOKEN` are bootstrap.\n- `GITHUB_APP_CLIENT_SECRET`, `GITHUB_APP_PRIVATE_KEY`, `GITHUB_TOKEN`, Slack tokens, Daytona, Brave, and common LLM API keys are optional vault secrets.\n- `GH_TOKEN` is not classified.\n- non-secret config names such as `GITHUB_BASE_URL`, `SLACK_BASE_URL`, and `DAYTONA_API_URL` are not classified.\n\n- [ ] **Step 4: Run the focused tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-static\n```\n\nExpected: all `fabro-static` tests pass.\n\n- [ ] **Step 5: Commit**\n\n```bash\ngit add lib/crates/fabro-static/src/lib.rs lib/crates/fabro-static/src/secret_registry.rs\ngit commit -m \"refactor: classify server secret scopes\"\n```\n\n---\n\n## Task 2: Enforce Bootstrap Boundaries In The Secret API\n\n**Files:**\n\n- Modify: `lib/crates/fabro-server/src/server/handler/secrets.rs`\n- Test: existing server handler tests or new focused tests near secret handler coverage\n\n- [ ] **Step 1: Reject bootstrap secrets in `create_secret`**\n\nBefore OAuth parsing or Daytona validation, reject `SecretScope::Bootstrap`:\n\n```rust\nif fabro_static::is_bootstrap_secret(&name) {\n return ApiError::bad_request(format!(\n \"{name} is a bootstrap secret; configure it with process env or server.env\"\n ))\n .into_response();\n}\n```\n\n- [ ] **Step 2: Keep optional and unknown secret writes allowed**\n\nDo not reject unknown names. Workflows may define arbitrary vault-visible secrets.\n\n- [ ] **Step 3: Add API tests**\n\nAdd tests proving:\n\n- `POST /secrets` with `SESSION_SECRET` returns `400`.\n- `POST /secrets` with `FABRO_DEV_TOKEN` returns `400`.\n- `POST /secrets` with `GITHUB_APP_CLIENT_SECRET` succeeds.\n- `POST /secrets` with a custom name such as `CUSTOM_WORKFLOW_TOKEN` succeeds.\n\n- [ ] **Step 4: Run focused tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-server secret\n```\n\nExpected: secret handler tests pass.\n\n- [ ] **Step 5: Commit**\n\n```bash\ngit add lib/crates/fabro-server/src/server/handler/secrets.rs lib/crates/fabro-server\ngit commit -m \"fix: reject bootstrap secrets in vault API\"\n```\n\n---\n\n## Task 3: Replace Server Optional Lookups With Vault-Only Lookups\n\n**Files:**\n\n- Modify: `lib/crates/fabro-server/src/server.rs`\n- Modify: `lib/crates/fabro-server/src/diagnostics.rs`\n- Modify: `lib/crates/fabro-server/src/run_files.rs`\n- Modify: `lib/crates/fabro-server/src/run_manifest.rs`\n- Modify: `lib/crates/fabro-server/src/server/handler/sandbox.rs`\n- Modify: `lib/crates/fabro-server/src/server/handler/sessions.rs`\n- Test: `lib/crates/fabro-server/src/server/tests.rs` and existing handler tests\n\n- [ ] **Step 1: Add explicit helpers on `AppState`**\n\nReplace `vault_or_env` and `vault_or_env_pub` with:\n\n```rust\npub(crate) fn vault_secret(&self, name: &str) -> Option {\n self.vault\n .try_read()\n .ok()\n .and_then(|vault| vault.get(name).map(str::to_string))\n}\n\nfn config_env_lookup(&self, name: &str) -> Option {\n (self.env_lookup)(name)\n}\n```\n\nKeep `server_secret` for bootstrap secrets only.\n\n- [ ] **Step 2: Change Daytona secret reads**\n\nUse `state.vault_secret(EnvVars::DAYTONA_API_KEY)` wherever a Daytona API key is required. Keep non-secret Daytona URL and organization settings on `env_lookup` or settings-derived configuration, not vault lookup.\n\n- [ ] **Step 3: Change GitHub token reads**\n\nIn `github_credentials`, resolve token strategy only through:\n\n```rust\nlet token = self\n .vault_secret(EnvVars::GITHUB_TOKEN)\n .as_deref()\n .map(str::trim)\n .filter(|token| !token.is_empty())\n .map(str::to_string);\n```\n\nRemove the `GH_TOKEN` fallback and update the error message to say:\n\n```text\nGITHUB_TOKEN not configured -- run fabro install or run fabro secret set GITHUB_TOKEN\n```\n\n- [ ] **Step 4: Change diagnostics and handlers**\n\nReplace `state.vault_or_env(...)` and `state.vault_or_env_pub(...)` with `state.vault_secret(...)` for optional secret checks. Update diagnostics remediation text to use `fabro secret set`.\n\n- [ ] **Step 5: Add regression tests**\n\nAdd tests proving:\n\n- `DAYTONA_API_KEY` in process env but absent from vault is treated as missing by server diagnostics.\n- `GITHUB_TOKEN` in process env but absent from vault is treated as missing by token strategy.\n- `GH_TOKEN` in vault or process env is ignored by server runtime.\n- `DAYTONA_API_KEY` in vault is accepted.\n\n- [ ] **Step 6: Run focused tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-server daytona\ncargo nextest run -p fabro-server github\n```\n\nExpected: relevant server tests pass.\n\n- [ ] **Step 7: Commit**\n\n```bash\ngit add lib/crates/fabro-server\ngit commit -m \"refactor: resolve optional server secrets from vault only\"\n```\n\n---\n\n## Task 4: Make Server LLM Credentials Vault-Only\n\n**Files:**\n\n- Modify: `lib/crates/fabro-auth/src/vault_source.rs`\n- Modify: `lib/crates/fabro-server/src/server.rs`\n- Test: `lib/crates/fabro-auth/src/vault_source.rs`, `lib/crates/fabro-server/src/server/tests.rs`\n\n- [ ] **Step 1: Add an explicit vault-only constructor**\n\nAdd this constructor to `VaultCredentialSource`:\n\n```rust\n#[must_use]\npub fn vault_only(vault: Arc>) -> Self {\n Self::with_env_lookup(vault, |_| None)\n}\n```\n\n- [ ] **Step 2: Use vault-only source in server app state**\n\nIn `build_app_state`, change the LLM source construction from `with_env_lookup(... env_lookup ...)` to:\n\n```rust\nlet llm_source: Arc =\n Arc::new(VaultCredentialSource::vault_only(Arc::clone(&vault)));\n```\n\n- [ ] **Step 3: Keep CLI/library env sources explicit**\n\nDo not remove `EnvCredentialSource`. Do not change direct CLI/library flows that intentionally choose env-backed credentials outside server runtime.\n\n- [ ] **Step 4: Add tests**\n\nAdd tests proving:\n\n- `VaultCredentialSource::vault_only` does not resolve process env values.\n- Server readiness sees a provider configured only when the matching vault secret exists.\n\n- [ ] **Step 5: Run focused tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-auth\ncargo nextest run -p fabro-server llm\n```\n\nExpected: auth and server LLM tests pass.\n\n- [ ] **Step 6: Commit**\n\n```bash\ngit add lib/crates/fabro-auth/src/vault_source.rs lib/crates/fabro-server/src/server.rs lib/crates/fabro-server/src/server/tests.rs\ngit commit -m \"fix: use vault-only llm credentials in server runtime\"\n```\n\n---\n\n## Task 5: Move GitHub App Runtime Secrets To Vault\n\n**Files:**\n\n- Modify: `lib/crates/fabro-server/src/server.rs`\n- Modify: `lib/crates/fabro-server/src/web_auth.rs`\n- Modify: `lib/crates/fabro-server/src/github_webhooks.rs`\n- Modify: `lib/crates/fabro-server/src/diagnostics.rs`\n- Modify: `lib/crates/fabro-server/src/startup.rs`\n- Modify: `lib/crates/fabro-server/src/serve.rs`\n- Modify: `lib/crates/fabro-server/src/jwt_auth.rs`\n- Test: server startup, auth, webhook, diagnostics, worker command tests\n\n- [ ] **Step 1: Read GitHub App private key from vault**\n\nIn `AppState::github_credentials`, replace:\n\n```rust\nlet raw = self.server_secret(EnvVars::GITHUB_APP_PRIVATE_KEY);\n```\n\nwith:\n\n```rust\nlet raw = self.vault_secret(EnvVars::GITHUB_APP_PRIVATE_KEY);\n```\n\n- [ ] **Step 2: Read OAuth client secret from vault**\n\nIn the GitHub OAuth callback handler, replace `state.server_secret(EnvVars::GITHUB_APP_CLIENT_SECRET)` with `state.vault_secret(EnvVars::GITHUB_APP_CLIENT_SECRET)`.\n\n- [ ] **Step 3: Read webhook secret from vault**\n\nReplace webhook secret resolution from `server_secret(WEBHOOK_SECRET_ENV)` to `vault_secret(WEBHOOK_SECRET_ENV)`. Startup logging should report webhook presence based on the vault value after the vault is loaded.\n\n- [ ] **Step 4: Validate GitHub auth after vault load**\n\nChange startup validation so `SESSION_SECRET` and `FABRO_DEV_TOKEN` are read from `ServerSecrets`, while `GITHUB_APP_CLIENT_SECRET` is read from the vault.\n\nUse a composite lookup for auth validation:\n\n```rust\nlet auth_secret_lookup = |name: &str| match name {\n EnvVars::GITHUB_APP_CLIENT_SECRET => vault.get(name).map(str::to_string),\n _ => server_secrets.get(name),\n};\n```\n\nLoad the vault before calling GitHub-auth validation. Pass the loaded vault into `build_app_state` or factor vault loading so the server does not perform inconsistent duplicate loads.\n\n- [ ] **Step 5: Update worker GitHub App key injection**\n\nWhere the worker command currently forwards `GITHUB_APP_PRIVATE_KEY` from `server_secret`, forward it from `vault_secret`. Keep the explicit worker injection because worker environments remain scrubbed by default.\n\n- [ ] **Step 6: Update tests**\n\nAdd or change tests proving:\n\n- GitHub auth enabled with `GITHUB_APP_CLIENT_SECRET` only in `server.env` fails startup.\n- GitHub auth enabled with `GITHUB_APP_CLIENT_SECRET` in vault passes startup.\n- OAuth callback reads the vault client secret.\n- Webhook verification reads the vault webhook secret.\n- Worker command forwards the GitHub App private key from vault.\n- Diagnostics reports missing GitHub App secrets based on vault, not `server.env`.\n\n- [ ] **Step 7: Run focused tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-server github\ncargo nextest run -p fabro-server worker_auth\ncargo nextest run -p fabro-cli server_start\n```\n\nExpected: GitHub auth, webhook, worker, and startup tests pass.\n\n- [ ] **Step 8: Commit**\n\n```bash\ngit add lib/crates/fabro-server lib/crates/fabro-cli/tests\ngit commit -m \"fix: store github app runtime secrets in vault\"\n```\n\n---\n\n## Task 6: Move Slack To Vault-Only Credentials\n\n**Files:**\n\n- Modify: `lib/crates/fabro-server/src/server.rs`\n- Modify: `lib/crates/fabro-slack/src/config.rs` only if names or status messages need adjustment\n- Test: Slack credential resolution and server app-state tests\n\n- [ ] **Step 1: Resolve Slack tokens from vault**\n\nIn `build_app_state`, replace:\n\n```rust\nresolve_slack_credentials_status_with_lookup(|name| server_secrets.get(name))\n```\n\nwith:\n\n```rust\nresolve_slack_credentials_status_with_lookup(|name| {\n vault.try_read().ok().and_then(|vault| vault.get(name).map(str::to_string))\n})\n```\n\nIf the implementation already holds a synchronous vault read guard in this block, reuse that guard rather than calling `try_read` repeatedly.\n\n- [ ] **Step 2: Keep Slack base URL out of the secret model**\n\nLeave `SLACK_BASE_URL` as a non-secret test/development override.

Use a boolean:\n\n```rust\n.field(\n \"brave_search_configured\",\n &self.tool_secrets.brave_search_api_key.is_some(),\n)\n```\n\n- [ ] **Step 2: Pass the Brave key into tool registration**\n\nChange `register_core_tools`:\n\n```rust\nregistry.register(make_web_search_tool_with_api_key(\n config.tool_secrets.brave_search_api_key.clone(),\n));\n```\n\nRemove the process-env-reading `make_web_search_tool` wrapper.\n\n- [ ] **Step 3: Improve the missing-key message**\n\nChange the error text from “environment variable is not set” to:\n\n```text\nBRAVE_SEARCH_API_KEY is not configured\n```\n\n- [ ] **Step 4: Populate `SessionOptions.tool_secrets` in server runtime**\n\nWhere the server constructs agent sessions, set:\n\n```rust\ntool_secrets: ToolSecrets {\n brave_search_api_key: state.vault_secret(EnvVars::BRAVE_SEARCH_API_KEY),\n},\n```\n\nKeep direct CLI agent behavior explicit: if the CLI should support local env-backed Brave Search, set this field at the CLI boundary from `std::env::var(EnvVars::BRAVE_SEARCH_API_KEY).ok()`. Do not let the tool read process env internally.\n\n- [ ] **Step 5: Update tests**\n\nAdd tests proving:\n\n- `make_web_search_tool_with_api_key(None)` returns `BRAVE_SEARCH_API_KEY is not configured`.\n- `register_core_tools` wires `SessionOptions.tool_secrets.brave_search_api_key` into the web search tool.\n- Server diagnostics and server-created sessions both use the same vault-backed key.\n\n- [ ] **Step 6: Run focused tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-agent web_search\ncargo nextest run -p fabro-server brave\n```\n\nExpected: Brave tests pass.\n\n- [ ] **Step 7: Commit**\n\n```bash\ngit add lib/crates/fabro-agent lib/crates/fabro-server\ngit commit -m \"fix: pass brave search credentials through server configuration\"\n```\n\n---\n\n## Task 8: Update Install Mode Persistence\n\n**Files:**\n\n- Modify: `lib/crates/fabro-server/src/install.rs`\n- Modify: `lib/crates/fabro-cli/src/commands/install.rs`\n- Modify: install tests in `lib/crates/fabro-server/tests/it/api/install.rs` and `lib/crates/fabro-cli/tests/it/cmd/install.rs`\n\n- [ ] **Step 1: Server install writes GitHub App secrets to vault**\n\nIn `post_install_finish`, replace GitHub App `server_env_writes.push(...)` calls with `vault_secrets.push(...)` calls:\n\n```rust\nvault_secrets.push(VaultSecretWrite {\n name: EnvVars::GITHUB_APP_PRIVATE_KEY.to_string(),\n value: BASE64_STANDARD.encode(github.pem.as_bytes()),\n secret_type: VaultSecretType::File,\n description: None,\n});\n\nvault_secrets.push(VaultSecretWrite {\n name: EnvVars::GITHUB_APP_CLIENT_SECRET.to_string(),\n value: github.client_secret,\n secret_type: VaultSecretType::Token,\n description: None,\n});\n\nif let Some(secret) = github.webhook_secret {\n vault_secrets.push(VaultSecretWrite {\n name: EnvVars::GITHUB_APP_WEBHOOK_SECRET.to_string(),\n value: secret,\n secret_type: VaultSecretType::Token,\n description: None,\n });\n}\n```\n\n- [ ] **Step 2: Remove stale GitHub App keys from `server.env` during install persistence**\n\nAdd removals for:\n\n- `GITHUB_APP_PRIVATE_KEY`\n- `GITHUB_APP_CLIENT_SECRET`\n- `GITHUB_APP_WEBHOOK_SECRET`\n\nThis keeps greenfield installs clean and removes stale optional secrets if a developer has run earlier local install attempts.\n\n- [ ] **Step 3: Align CLI GitHub install helper**\n\nUpdate CLI install persistence so switching to GitHub App writes app secrets to vault and removes the app keys from `server.env`. Switching to token continues to write `GITHUB_TOKEN` to vault and remove app vault secrets.\n\n- [ ] **Step 4: Update install tests**\n\nAdd or change tests proving:\n\n- Browser install with GitHub App writes private key, client secret, and webhook secret to vault.\n- Browser install with GitHub App does not write those keys to `server.env`.\n- CLI GitHub App install writes app secrets to vault.\n- Switching strategies removes stale secrets from the other strategy.\n- `SESSION_SECRET`, `FABRO_DEV_TOKEN`, and object-store credentials remain in `server.env`.\n\n- [ ] **Step 5: Run focused tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-server install\ncargo nextest run -p fabro-cli install\n```\n\nExpected: install tests pass.\n\n- [ ] **Step 6: Commit**\n\n```bash\ngit add lib/crates/fabro-server/src/install.rs lib/crates/fabro-server/tests/it/api/install.rs lib/crates/fabro-cli/src/commands/install.rs lib/crates/fabro-cli/tests/it/cmd/install.rs\ngit commit -m \"fix: persist optional install secrets in vault\"\n```\n\n---\n\n## Task 9: Update Strategy And Public Docs\n\n**Files:**\n\n- Modify: `docs/internal/server-secrets-strategy.md`\n- Modify: `docs/public/administration/server-configuration.mdx`\n- Modify: `docs/public/administration/self-host-docker.mdx`\n- Modify: `docs/public/administration/deploy-railway.mdx`\n- Modify: `docs/public/integrations/github.mdx`\n- Modify: `docs/public/integrations/slack.mdx`\n- Modify: `docs/public/integrations/brave-search.mdx`\n- Modify: `docs/public/integrations/daytona.mdx`\n- Modify: LLM provider docs that still say server runtime reads provider keys from process env\n\n- [ ] **Step 1: Rewrite internal strategy**\n\nUpdate `server-secrets-strategy.md` to state:\n\n- `ServerSecrets` means bootstrap secrets only.\n- Bootstrap source precedence is process env then `server.env`.\n- Optional integration secrets are vault-only.\n- Requiredness is independent from source: GitHub auth may require a vault secret at startup.\n- Server worker env remains scrubbed and receives only explicit injected values.\n\n- [ ] **Step 2: Update administration docs**\n\nState that `server.env` is for:\n\n- `SESSION_SECRET`\n- `FABRO_DEV_TOKEN`\n- storage/object-store bootstrap credentials\n\nState that `server.env` is not used for:\n\n- Slack\n- Daytona\n- Brave Search\n- LLM provider keys\n- GitHub token\n- GitHub App private key/client secret/webhook secret\n\n- [ ] **Step 3: Update integration docs**\n\nFor each optional integration, show `fabro secret set` as the server-runtime configuration path:\n\n```bash\nfabro secret set BRAVE_SEARCH_API_KEY \nfabro secret set DAYTONA_API_KEY \nfabro secret set FABRO_SLACK_BOT_TOKEN \nfabro secret set FABRO_SLACK_APP_TOKEN \nfabro secret set GITHUB_TOKEN \n```\n\nFor GitHub App, document that install mode stores app secrets in vault.\n\n- [ ] **Step 4: Remove stale `server.env` guidance**\n\nSearch:\n\n```bash\nrg -n \"server.env|process env -> server.env|GITHUB_APP_CLIENT_SECRET|FABRO_SLACK\" docs/public docs/internal\n```\n\nEach result should either describe bootstrap secrets or explicitly say the secret is vault-only.\n\n- [ ] **Step 5: Commit**\n\n```bash\ngit add docs/internal docs/public\ngit commit -m \"docs: document vault-only optional secrets\"\n```\n\n---\n\n## Task 10: Final Verification And Cleanup\n\n**Files:**\n\n- Modify any touched tests or docs needed by final verification.\n\n- [ ] **Step 1: Search for removed server-runtime patterns**\n\nRun:\n\n```bash\nrg -n \"vault_or_env|vault_or_env_pub|GH_TOKEN|GITHUB_APP_CLIENT_SECRET.*server_secret|FABRO_SLACK_.*server_secret|BRAVE_SEARCH_API_KEY.*std::env|DAYTONA_API_KEY.*process_env\" lib/crates docs\n```\n\nExpected:\n\n- no server-runtime `vault_or_env` helper remains;\n- no server-runtime `GH_TOKEN` fallback remains;\n- no optional secret docs claim `server.env` is a valid server-runtime source;\n- live-test annotations and explicit CLI/library env usage may remain.\n\n- [ ] **Step 2: Run focused crate tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-static\ncargo nextest run -p fabro-auth\ncargo nextest run -p fabro-agent web_search\ncargo nextest run -p fabro-slack\ncargo nextest run -p fabro-server\ncargo nextest run -p fabro-cli install\n```\n\nExpected: all listed tests pass.\n\n- [ ] **Step 3: Run workspace quality checks**\n\nRun:\n\n```bash\ncargo +nightly-2026-04-14 fmt --check --all\ncargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings\n```\n\nExpected: formatting and clippy pass.\n\n- [ ] **Step 4: Run one end-to-end install smoke if credentials are available**\n\nRun a non-live smoke that exercises install persistence and restart validation through existing install tests.

Keep `ServerSecrets` focused on bootstrap startup/runtime requirements, add vault-only helpers for optional integrations, and wire install mode so it can write optional secrets before enabling features such as GitHub auth.\n\n**Tech Stack:** Rust workspace crates (`fabro-static`, `fabro-auth`, `fabro-agent`, `fabro-server`, `fabro-cli`), existing vault storage, existing install persistence, existing docs under `docs/internal` and `docs/public`.\n\n---\n\n## Decisions Locked In\n\n- `server.env` is only for bootstrap/runtime secrets that the server may need before the vault can be used.\n- Process env is also bootstrap-only for server runtime. Optional server integrations do not read process env.\n- Vault is the only server/runtime source for optional integration secrets.\n- Optional secrets may be workflow-visible for now.\n- No compatibility shims or fallback aliases are required. Remove server-runtime `GH_TOKEN` fallback and optional `server.env` fallbacks.\n- Non-secret configuration, such as base URLs, org IDs, or catalog settings, remains configuration. This plan only governs secrets.\n- CLI/library code may still use env-backed credential sources where explicitly selected outside server runtime. The server runtime must not use that path for optional integrations.\n\n## Secret Model\n\nBootstrap secrets:\n\n- `SESSION_SECRET`\n- `FABRO_DEV_TOKEN`\n- object-store/storage credentials resolved by current server object-store builders, including manual AWS credentials such as `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, and `AWS_SESSION_TOKEN`\n\nOptional vault secrets:\n\n- LLM provider API keys and OAuth credential records\n- `FABRO_SLACK_BOT_TOKEN`\n- `FABRO_SLACK_APP_TOKEN`\n- `DAYTONA_API_KEY`\n- `BRAVE_SEARCH_API_KEY`\n- `GITHUB_TOKEN`\n- `GITHUB_APP_PRIVATE_KEY`\n- `GITHUB_APP_CLIENT_SECRET`\n- `GITHUB_APP_WEBHOOK_SECRET`\n\n## Change Map\n\n- Create `lib/crates/fabro-static/src/secret_registry.rs` for shared classification.\n- Modify `lib/crates/fabro-static/src/lib.rs` to export the registry.\n- Modify `lib/crates/fabro-server/src/server_secrets.rs` to make the bootstrap boundary explicit in tests and naming.\n- Modify `lib/crates/fabro-server/src/server.rs`, `diagnostics.rs`, `run_files.rs`, `run_manifest.rs`, `web_auth.rs`, `github_webhooks.rs`, and server handlers under `server/handler/` to use vault-only optional lookup.\n- Modify `lib/crates/fabro-server/src/startup.rs`, `serve.rs`, and `jwt_auth.rs` so GitHub auth validates `GITHUB_APP_CLIENT_SECRET` from vault while session/dev-token auth still validates bootstrap secrets.\n- Modify `lib/crates/fabro-auth/src/vault_source.rs` to expose an explicit vault-only credential source constructor for server runtime.\n- Modify `lib/crates/fabro-agent/src/config.rs` and `tools.rs` so `web_search` receives `BRAVE_SEARCH_API_KEY` explicitly instead of reading process env inside the tool.\n- Modify install flows in `lib/crates/fabro-server/src/install.rs` and `lib/crates/fabro-cli/src/commands/install.rs` so GitHub App secrets are written to vault, not `server.env`.\n- Modify `lib/crates/fabro-server/src/server/handler/secrets.rs` so bootstrap secrets cannot be written through the vault API.\n- Update public and internal docs after behavior is implemented.\n\n---\n\n## Task 1: Add The Shared Secret Registry\n\n**Files:**\n\n- Create: `lib/crates/fabro-static/src/secret_registry.rs`\n- Modify: `lib/crates/fabro-static/src/lib.rs`\n- Test: unit tests in `secret_registry.rs`\n\n- [ ] **Step 1: Define the registry types and classified names**\n\nCreate `secret_registry.rs` with this shape:\n\n```rust\nuse crate::EnvVars;\n\n#[derive(Clone, Copy, Debug, PartialEq, Eq)]\npub enum SecretScope {\n Bootstrap,\n OptionalVault,\n}\n\nconst BOOTSTRAP_SECRETS: &[&str] = &[\n EnvVars::SESSION_SECRET,\n EnvVars::FABRO_DEV_TOKEN,\n EnvVars::AWS_ACCESS_KEY_ID,\n EnvVars::AWS_SECRET_ACCESS_KEY,\n EnvVars::AWS_SESSION_TOKEN,\n];\n\nconst OPTIONAL_VAULT_SECRETS: &[&str] = &[\n EnvVars::ANTHROPIC_API_KEY,\n EnvVars::BRAVE_SEARCH_API_KEY,\n EnvVars::FABRO_SLACK_APP_TOKEN,\n EnvVars::FABRO_SLACK_BOT_TOKEN,\n EnvVars::GEMINI_API_KEY,\n EnvVars::GITHUB_APP_CLIENT_SECRET,\n EnvVars::GITHUB_APP_PRIVATE_KEY,\n EnvVars::GITHUB_APP_WEBHOOK_SECRET,\n EnvVars::GITHUB_TOKEN,\n EnvVars::INCEPTION_API_KEY,\n EnvVars::KIMI_API_KEY,\n EnvVars::MINIMAX_API_KEY,\n EnvVars::OPENAI_API_KEY,\n EnvVars::ZAI_API_KEY,\n EnvVars::DAYTONA_API_KEY,\n];\n\npub fn secret_scope(name: &str) -> Option {\n if BOOTSTRAP_SECRETS.contains(&name) {\n Some(SecretScope::Bootstrap)\n } else if OPTIONAL_VAULT_SECRETS.contains(&name) {\n Some(SecretScope::OptionalVault)\n } else {\n None\n }\n}\n\npub fn is_bootstrap_secret(name: &str) -> bool {\n secret_scope(name) == Some(SecretScope::Bootstrap)\n}\n\npub fn is_optional_vault_secret(name: &str) -> bool {\n secret_scope(name) == Some(SecretScope::OptionalVault)\n}\n```\n\n- [ ] **Step 2: Export the registry**\n\nModify `lib.rs`:\n\n```rust\nmod env_vars;\nmod secret_registry;\n\npub use env_vars::EnvVars;\npub use secret_registry::{\n SecretScope, is_bootstrap_secret, is_optional_vault_secret, secret_scope,\n};\n```\n\n- [ ] **Step 3: Add registry tests**\n\nAdd tests proving:\n\n- `SESSION_SECRET` and `FABRO_DEV_TOKEN` are bootstrap.\n- `GITHUB_APP_CLIENT_SECRET`, `GITHUB_APP_PRIVATE_KEY`, `GITHUB_TOKEN`, Slack tokens, Daytona, Brave, and common LLM API keys are optional vault secrets.\n- `GH_TOKEN` is not classified.\n- non-secret config names such as `GITHUB_BASE_URL`, `SLACK_BASE_URL`, and `DAYTONA_API_URL` are not classified.\n\n- [ ] **Step 4: Run the focused tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-static\n```\n\nExpected: all `fabro-static` tests pass.\n\n- [ ] **Step 5: Commit**\n\n```bash\ngit add lib/crates/fabro-static/src/lib.rs lib/crates/fabro-static/src/secret_registry.rs\ngit commit -m \"refactor: classify server secret scopes\"\n```\n\n---\n\n## Task 2: Enforce Bootstrap Boundaries In The Secret API\n\n**Files:**\n\n- Modify: `lib/crates/fabro-server/src/server/handler/secrets.rs`\n- Test: existing server handler tests or new focused tests near secret handler coverage\n\n- [ ] **Step 1: Reject bootstrap secrets in `create_secret`**\n\nBefore OAuth parsing or Daytona validation, reject `SecretScope::Bootstrap`:\n\n```rust\nif fabro_static::is_bootstrap_secret(&name) {\n return ApiError::bad_request(format!(\n \"{name} is a bootstrap secret; configure it with process env or server.env\"\n ))\n .into_response();\n}\n```\n\n- [ ] **Step 2: Keep optional and unknown secret writes allowed**\n\nDo not reject unknown names. Workflows may define arbitrary vault-visible secrets.\n\n- [ ] **Step 3: Add API tests**\n\nAdd tests proving:\n\n- `POST /secrets` with `SESSION_SECRET` returns `400`.\n- `POST /secrets` with `FABRO_DEV_TOKEN` returns `400`.\n- `POST /secrets` with `GITHUB_APP_CLIENT_SECRET` succeeds.\n- `POST /secrets` with a custom name such as `CUSTOM_WORKFLOW_TOKEN` succeeds.\n\n- [ ] **Step 4: Run focused tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-server secret\n```\n\nExpected: secret handler tests pass.\n\n- [ ] **Step 5: Commit**\n\n```bash\ngit add lib/crates/fabro-server/src/server/handler/secrets.rs lib/crates/fabro-server\ngit commit -m \"fix: reject bootstrap secrets in vault API\"\n```\n\n---\n\n## Task 3: Replace Server Optional Lookups With Vault-Only Lookups\n\n**Files:**\n\n- Modify: `lib/crates/fabro-server/src/server.rs`\n- Modify: `lib/crates/fabro-server/src/diagnostics.rs`\n- Modify: `lib/crates/fabro-server/src/run_files.rs`\n- Modify: `lib/crates/fabro-server/src/run_manifest.rs`\n- Modify: `lib/crates/fabro-server/src/server/handler/sandbox.rs`\n- Modify: `lib/crates/fabro-server/src/server/handler/sessions.rs`\n- Test: `lib/crates/fabro-server/src/server/tests.rs` and existing handler tests\n\n- [ ] **Step 1: Add explicit helpers on `AppState`**\n\nReplace `vault_or_env` and `vault_or_env_pub` with:\n\n```rust\npub(crate) fn vault_secret(&self, name: &str) -> Option {\n self.vault\n .try_read()\n .ok()\n .and_then(|vault| vault.get(name).map(str::to_string))\n}\n\nfn config_env_lookup(&self, name: &str) -> Option {\n (self.env_lookup)(name)\n}\n```\n\nKeep `server_secret` for bootstrap secrets only.\n\n- [ ] **Step 2: Change Daytona secret reads**\n\nUse `state.vault_secret(EnvVars::DAYTONA_API_KEY)` wherever a Daytona API key is required. Keep non-secret Daytona URL and organization settings on `env_lookup` or settings-derived configuration, not vault lookup.\n\n- [ ] **Step 3: Change GitHub token reads**\n\nIn `github_credentials`, resolve token strategy only through:\n\n```rust\nlet token = self\n .vault_secret(EnvVars::GITHUB_TOKEN)\n .as_deref()\n .map(str::trim)\n .filter(|token| !token.is_empty())\n .map(str::to_string);\n```\n\nRemove the `GH_TOKEN` fallback and update the error message to say:\n\n```text\nGITHUB_TOKEN not configured -- run fabro install or run fabro secret set GITHUB_TOKEN\n```\n\n- [ ] **Step 4: Change diagnostics and handlers**\n\nReplace `state.vault_or_env(...)` and `state.vault_or_env_pub(...)` with `state.vault_secret(...)` for optional secret checks. Update diagnostics remediation text to use `fabro secret set`.\n\n- [ ] **Step 5: Add regression tests**\n\nAdd tests proving:\n\n- `DAYTONA_API_KEY` in process env but absent from vault is treated as missing by server diagnostics.\n- `GITHUB_TOKEN` in process env but absent from vault is treated as missing by token strategy.\n- `GH_TOKEN` in vault or process env is ignored by server runtime.\n- `DAYTONA_API_KEY` in vault is accepted.\n\n- [ ] **Step 6: Run focused tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-server daytona\ncargo nextest run -p fabro-server github\n```\n\nExpected: relevant server tests pass.\n\n- [ ] **Step 7: Commit**\n\n```bash\ngit add lib/crates/fabro-server\ngit commit -m \"refactor: resolve optional server secrets from vault only\"\n```\n\n---\n\n## Task 4: Make Server LLM Credentials Vault-Only\n\n**Files:**\n\n- Modify: `lib/crates/fabro-auth/src/vault_source.rs`\n- Modify: `lib/crates/fabro-server/src/server.rs`\n- Test: `lib/crates/fabro-auth/src/vault_source.rs`, `lib/crates/fabro-server/src/server/tests.rs`\n\n- [ ] **Step 1: Add an explicit vault-only constructor**\n\nAdd this constructor to `VaultCredentialSource`:\n\n```rust\n#[must_use]\npub fn vault_only(vault: Arc>) -> Self {\n Self::with_env_lookup(vault, |_| None)\n}\n```\n\n- [ ] **Step 2: Use vault-only source in server app state**\n\nIn `build_app_state`, change the LLM source construction from `with_env_lookup(... env_lookup ...)` to:\n\n```rust\nlet llm_source: Arc =\n Arc::new(VaultCredentialSource::vault_only(Arc::clone(&vault)));\n```\n\n- [ ] **Step 3: Keep CLI/library env sources explicit**\n\nDo not remove `EnvCredentialSource`. Do not change direct CLI/library flows that intentionally choose env-backed credentials outside server runtime.\n\n- [ ] **Step 4: Add tests**\n\nAdd tests proving:\n\n- `VaultCredentialSource::vault_only` does not resolve process env values.\n- Server readiness sees a provider configured only when the matching vault secret exists.\n\n- [ ] **Step 5: Run focused tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-auth\ncargo nextest run -p fabro-server llm\n```\n\nExpected: auth and server LLM tests pass.\n\n- [ ] **Step 6: Commit**\n\n```bash\ngit add lib/crates/fabro-auth/src/vault_source.rs lib/crates/fabro-server/src/server.rs lib/crates/fabro-server/src/server/tests.rs\ngit commit -m \"fix: use vault-only llm credentials in server runtime\"\n```\n\n---\n\n## Task 5: Move GitHub App Runtime Secrets To Vault\n\n**Files:**\n\n- Modify: `lib/crates/fabro-server/src/server.rs`\n- Modify: `lib/crates/fabro-server/src/web_auth.rs`\n- Modify: `lib/crates/fabro-server/src/github_webhooks.rs`\n- Modify: `lib/crates/fabro-server/src/diagnostics.rs`\n- Modify: `lib/crates/fabro-server/src/startup.rs`\n- Modify: `lib/crates/fabro-server/src/serve.rs`\n- Modify: `lib/crates/fabro-server/src/jwt_auth.rs`\n- Test: server startup, auth, webhook, diagnostics, worker command tests\n\n- [ ] **Step 1: Read GitHub App private key from vault**\n\nIn `AppState::github_credentials`, replace:\n\n```rust\nlet raw = self.server_secret(EnvVars::GITHUB_APP_PRIVATE_KEY);\n```\n\nwith:\n\n```rust\nlet raw = self.vault_secret(EnvVars::GITHUB_APP_PRIVATE_KEY);\n```\n\n- [ ] **Step 2: Read OAuth client secret from vault**\n\nIn the GitHub OAuth callback handler, replace `state.server_secret(EnvVars::GITHUB_APP_CLIENT_SECRET)` with `state.vault_secret(EnvVars::GITHUB_APP_CLIENT_SECRET)`.\n\n- [ ] **Step 3: Read webhook secret from vault**\n\nReplace webhook secret resolution from `server_secret(WEBHOOK_SECRET_ENV)` to `vault_secret(WEBHOOK_SECRET_ENV)`. Startup logging should report webhook presence based on the vault value after the vault is loaded.\n\n- [ ] **Step 4: Validate GitHub auth after vault load**\n\nChange startup validation so `SESSION_SECRET` and `FABRO_DEV_TOKEN` are read from `ServerSecrets`, while `GITHUB_APP_CLIENT_SECRET` is read from the vault.\n\nUse a composite lookup for auth validation:\n\n```rust\nlet auth_secret_lookup = |name: &str| match name {\n EnvVars::GITHUB_APP_CLIENT_SECRET => vault.get(name).map(str::to_string),\n _ => server_secrets.get(name),\n};\n```\n\nLoad the vault before calling GitHub-auth validation. Pass the loaded vault into `build_app_state` or factor vault loading so the server does not perform inconsistent duplicate loads.\n\n- [ ] **Step 5: Update worker GitHub App key injection**\n\nWhere the worker command currently forwards `GITHUB_APP_PRIVATE_KEY` from `server_secret`, forward it from `vault_secret`. Keep the explicit worker injection because worker environments remain scrubbed by default.\n\n- [ ] **Step 6: Update tests**\n\nAdd or change tests proving:\n\n- GitHub auth enabled with `GITHUB_APP_CLIENT_SECRET` only in `server.env` fails startup.\n- GitHub auth enabled with `GITHUB_APP_CLIENT_SECRET` in vault passes startup.\n- OAuth callback reads the vault client secret.\n- Webhook verification reads the vault webhook secret.\n- Worker command forwards the GitHub App private key from vault.\n- Diagnostics reports missing GitHub App secrets based on vault, not `server.env`.\n\n- [ ] **Step 7: Run focused tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-server github\ncargo nextest run -p fabro-server worker_auth\ncargo nextest run -p fabro-cli server_start\n```\n\nExpected: GitHub auth, webhook, worker, and startup tests pass.\n\n- [ ] **Step 8: Commit**\n\n```bash\ngit add lib/crates/fabro-server lib/crates/fabro-cli/tests\ngit commit -m \"fix: store github app runtime secrets in vault\"\n```\n\n---\n\n## Task 6: Move Slack To Vault-Only Credentials\n\n**Files:**\n\n- Modify: `lib/crates/fabro-server/src/server.rs`\n- Modify: `lib/crates/fabro-slack/src/config.rs` only if names or status messages need adjustment\n- Test: Slack credential resolution and server app-state tests\n\n- [ ] **Step 1: Resolve Slack tokens from vault**\n\nIn `build_app_state`, replace:\n\n```rust\nresolve_slack_credentials_status_with_lookup(|name| server_secrets.get(name))\n```\n\nwith:\n\n```rust\nresolve_slack_credentials_status_with_lookup(|name| {\n vault.try_read().ok().and_then(|vault| vault.get(name).map(str::to_string))\n})\n```\n\nIf the implementation already holds a synchronous vault read guard in this block, reuse that guard rather than calling `try_read` repeatedly.\n\n- [ ] **Step 2: Keep Slack base URL out of the secret model**\n\nLeave `SLACK_BASE_URL` as a non-secret test/development override. Do not add it to the secret registry.\n\n- [ ] **Step 3: Update Slack tests**\n\nAdd tests proving:\n\n- Slack tokens in vault enable Slack service.\n- Slack tokens in `server.env` but absent from vault do not enable Slack service.\n- Missing vault tokens produce the existing disabled status with missing token names.\n\n- [ ] **Step 4: Run focused tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-slack\ncargo nextest run -p fabro-server slack\n```\n\nExpected: Slack tests pass.\n\n- [ ] **Step 5: Commit**\n\n```bash\ngit add lib/crates/fabro-server/src/server.rs lib/crates/fabro-slack/src/config.rs\ngit commit -m \"fix: resolve slack credentials from vault\"\n```\n\n---\n\n## Task 7: Make Brave Search Tool Use Server-Provided Secrets\n\n**Files:**\n\n- Modify: `lib/crates/fabro-agent/src/config.rs`\n- Modify: `lib/crates/fabro-agent/src/tools.rs`\n- Modify: server session/profile construction where `SessionOptions` are built\n- Test: `lib/crates/fabro-agent/src/tools.rs`, server diagnostics/tool integration tests\n\n- [ ] **Step 1: Add tool secret configuration**\n\nAdd to `config.rs`:\n\n```rust\n#[derive(Clone, Debug, Default, PartialEq, Eq)]\npub struct ToolSecrets {\n pub brave_search_api_key: Option,\n}\n```\n\nAdd this field to `SessionOptions`:\n\n```rust\npub tool_secrets: ToolSecrets,\n```\n\nDefault it to `ToolSecrets::default()` and include it in the debug impl without printing secret values. Use a boolean:\n\n```rust\n.field(\n \"brave_search_configured\",\n &self.tool_secrets.brave_search_api_key.is_some(),\n)\n```\n\n- [ ] **Step 2: Pass the Brave key into tool registration**\n\nChange `register_core_tools`:\n\n```rust\nregistry.register(make_web_search_tool_with_api_key(\n config.tool_secrets.brave_search_api_key.clone(),\n));\n```\n\nRemove the process-env-reading `make_web_search_tool` wrapper.\n\n- [ ] **Step 3: Improve the missing-key message**\n\nChange the error text from “environment variable is not set” to:\n\n```text\nBRAVE_SEARCH_API_KEY is not configured\n```\n\n- [ ] **Step 4: Populate `SessionOptions.tool_secrets` in server runtime**\n\nWhere the server constructs agent sessions, set:\n\n```rust\ntool_secrets: ToolSecrets {\n brave_search_api_key: state.vault_secret(EnvVars::BRAVE_SEARCH_API_KEY),\n},\n```\n\nKeep direct CLI agent behavior explicit: if the CLI should support local env-backed Brave Search, set this field at the CLI boundary from `std::env::var(EnvVars::BRAVE_SEARCH_API_KEY).ok()`. Do not let the tool read process env internally.\n\n- [ ] **Step 5: Update tests**\n\nAdd tests proving:\n\n- `make_web_search_tool_with_api_key(None)` returns `BRAVE_SEARCH_API_KEY is not configured`.\n- `register_core_tools` wires `SessionOptions.tool_secrets.brave_search_api_key` into the web search tool.\n- Server diagnostics and server-created sessions both use the same vault-backed key.\n\n- [ ] **Step 6: Run focused tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-agent web_search\ncargo nextest run -p fabro-server brave\n```\n\nExpected: Brave tests pass.\n\n- [ ] **Step 7: Commit**\n\n```bash\ngit add lib/crates/fabro-agent lib/crates/fabro-server\ngit commit -m \"fix: pass brave search credentials through server configuration\"\n```\n\n---\n\n## Task 8: Update Install Mode Persistence\n\n**Files:**\n\n- Modify: `lib/crates/fabro-server/src/install.rs`\n- Modify: `lib/crates/fabro-cli/src/commands/install.rs`\n- Modify: install tests in `lib/crates/fabro-server/tests/it/api/install.rs` and `lib/crates/fabro-cli/tests/it/cmd/install.rs`\n\n- [ ] **Step 1: Server install writes GitHub App secrets to vault**\n\nIn `post_install_finish`, replace GitHub App `server_env_writes.push(...)` calls with `vault_secrets.push(...)` calls:\n\n```rust\nvault_secrets.push(VaultSecretWrite {\n name: EnvVars::GITHUB_APP_PRIVATE_KEY.to_string(),\n value: BASE64_STANDARD.encode(github.pem.as_bytes()),\n secret_type: VaultSecretType::File,\n description: None,\n});\n\nvault_secrets.push(VaultSecretWrite {\n name: EnvVars::GITHUB_APP_CLIENT_SECRET.to_string(),\n value: github.client_secret,\n secret_type: VaultSecretType::Token,\n description: None,\n});\n\nif let Some(secret) = github.webhook_secret {\n vault_secrets.push(VaultSecretWrite {\n name: EnvVars::GITHUB_APP_WEBHOOK_SECRET.to_string(),\n value: secret,\n secret_type: VaultSecretType::Token,\n description: None,\n });\n}\n```\n\n- [ ] **Step 2: Remove stale GitHub App keys from `server.env` during install persistence**\n\nAdd removals for:\n\n- `GITHUB_APP_PRIVATE_KEY`\n- `GITHUB_APP_CLIENT_SECRET`\n- `GITHUB_APP_WEBHOOK_SECRET`\n\nThis keeps greenfield installs clean and removes stale optional secrets if a developer has run earlier local install attempts.\n\n- [ ] **Step 3: Align CLI GitHub install helper**\n\nUpdate CLI install persistence so switching to GitHub App writes app secrets to vault and removes the app keys from `server.env`. Switching to token continues to write `GITHUB_TOKEN` to vault and remove app vault secrets.\n\n- [ ] **Step 4: Update install tests**\n\nAdd or change tests proving:\n\n- Browser install with GitHub App writes private key, client secret, and webhook secret to vault.\n- Browser install with GitHub App does not write those keys to `server.env`.\n- CLI GitHub App install writes app secrets to vault.\n- Switching strategies removes stale secrets from the other strategy.\n- `SESSION_SECRET`, `FABRO_DEV_TOKEN`, and object-store credentials remain in `server.env`.\n\n- [ ] **Step 5: Run focused tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-server install\ncargo nextest run -p fabro-cli install\n```\n\nExpected: install tests pass.\n\n- [ ] **Step 6: Commit**\n\n```bash\ngit add lib/crates/fabro-server/src/install.rs lib/crates/fabro-server/tests/it/api/install.rs lib/crates/fabro-cli/src/commands/install.rs lib/crates/fabro-cli/tests/it/cmd/install.rs\ngit commit -m \"fix: persist optional install secrets in vault\"\n```\n\n---\n\n## Task 9: Update Strategy And Public Docs\n\n**Files:**\n\n- Modify: `docs/internal/server-secrets-strategy.md`\n- Modify: `docs/public/administration/server-configuration.mdx`\n- Modify: `docs/public/administration/self-host-docker.mdx`\n- Modify: `docs/public/administration/deploy-railway.mdx`\n- Modify: `docs/public/integrations/github.mdx`\n- Modify: `docs/public/integrations/slack.mdx`\n- Modify: `docs/public/integrations/brave-search.mdx`\n- Modify: `docs/public/integrations/daytona.mdx`\n- Modify: LLM provider docs that still say server runtime reads provider keys from process env\n\n- [ ] **Step 1: Rewrite internal strategy**\n\nUpdate `server-secrets-strategy.md` to state:\n\n- `ServerSecrets` means bootstrap secrets only.\n- Bootstrap source precedence is process env then `server.env`.\n- Optional integration secrets are vault-only.\n- Requiredness is independent from source: GitHub auth may require a vault secret at startup.\n- Server worker env remains scrubbed and receives only explicit injected values.\n\n- [ ] **Step 2: Update administration docs**\n\nState that `server.env` is for:\n\n- `SESSION_SECRET`\n- `FABRO_DEV_TOKEN`\n- storage/object-store bootstrap credentials\n\nState that `server.env` is not used for:\n\n- Slack\n- Daytona\n- Brave Search\n- LLM provider keys\n- GitHub token\n- GitHub App private key/client secret/webhook secret\n\n- [ ] **Step 3: Update integration docs**\n\nFor each optional integration, show `fabro secret set` as the server-runtime configuration path:\n\n```bash\nfabro secret set BRAVE_SEARCH_API_KEY \nfabro secret set DAYTONA_API_KEY \nfabro secret set FABRO_SLACK_BOT_TOKEN \nfabro secret set FABRO_SLACK_APP_TOKEN \nfabro secret set GITHUB_TOKEN \n```\n\nFor GitHub App, document that install mode stores app secrets in vault.\n\n- [ ] **Step 4: Remove stale `server.env` guidance**\n\nSearch:\n\n```bash\nrg -n \"server.env|process env -> server.env|GITHUB_APP_CLIENT_SECRET|FABRO_SLACK\" docs/public docs/internal\n```\n\nEach result should either describe bootstrap secrets or explicitly say the secret is vault-only.\n\n- [ ] **Step 5: Commit**\n\n```bash\ngit add docs/internal docs/public\ngit commit -m \"docs: document vault-only optional secrets\"\n```\n\n---\n\n## Task 10: Final Verification And Cleanup\n\n**Files:**\n\n- Modify any touched tests or docs needed by final verification.\n\n- [ ] **Step 1: Search for removed server-runtime patterns**\n\nRun:\n\n```bash\nrg -n \"vault_or_env|vault_or_env_pub|GH_TOKEN|GITHUB_APP_CLIENT_SECRET.*server_secret|FABRO_SLACK_.*server_secret|BRAVE_SEARCH_API_KEY.*std::env|DAYTONA_API_KEY.*process_env\" lib/crates docs\n```\n\nExpected:\n\n- no server-runtime `vault_or_env` helper remains;\n- no server-runtime `GH_TOKEN` fallback remains;\n- no optional secret docs claim `server.env` is a valid server-runtime source;\n- live-test annotations and explicit CLI/library env usage may remain.\n\n- [ ] **Step 2: Run focused crate tests**\n\nRun:\n\n```bash\ncargo nextest run -p fabro-static\ncargo nextest run -p fabro-auth\ncargo nextest run -p fabro-agent web_search\ncargo nextest run -p fabro-slack\ncargo nextest run -p fabro-server\ncargo nextest run -p fabro-cli install\n```\n\nExpected: all listed tests pass.\n\n- [ ] **Step 3: Run workspace quality checks**\n\nRun:\n\n```bash\ncargo +nightly-2026-04-14 fmt --check --all\ncargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings\n```\n\nExpected: formatting and clippy pass.\n\n- [ ] **Step 4: Run one end-to-end install smoke if credentials are available**\n\nRun a non-live smoke that exercises install persistence and restart validation through existing install tests.

The working dir is /home/daytona/workspace/fabro.\n\nContext: This change introduces a shared secret registry in `fabro-static`, classifies secrets as Bootstrap vs OptionalVault, and rewires the server to read optional secrets only from the vault (not server.env/process env). It changes Slack/Daytona/GitHub/Brave/LLM credential resolution, install flows, and adds a `VaultCredentialSource::vault_only` constructor.\n\nYour job: Review for efficiency issues. Focus on real, non-trivial issues.\n\nSpecifically check:\n1. Unnecessary work: the new `vault_secret` method uses `self.vault.try_read().ok().and_then(...)`. Look at every caller and check if it's invoked in a tight loop or hot path. Are there sites that call it twice when once would do?\n2. Look at `build_app_state` in server.rs — does the new code hold a vault read guard once, or re-acquire it for every secret lookup? Slack resolution especially needs multiple lookups (BOT_TOKEN + APP_TOKEN).\n3. Diagnostics — does it iterate many secrets sequentially when batched?\n4. Startup: the GitHub auth validation now reads vault. Is vault loaded twice during startup (once for validation, once for app state)? The plan explicitly says: \"Pass the loaded vault into build_app_state or factor vault loading so the server does not perform inconsistent duplicate loads.\"\n5. Hot path bloat: per-session creation, does `SessionOptions.tool_secrets` get populated via `state.vault_secret(...)` on every session? That's fine if rare, problematic if hot. Check sessions.rs and tools.rs.\n6. Install.rs persistence: does it remove server.env keys one-by-one when batched?\n7. Memory: the new tests in server/tests.rs allocate fresh app states — any obvious leak / unbounded growth?\n8. The `vault.try_read()` failure case — silently returns None. Is that masking a problem (lock contention) or intentional?\n\nRead the diff first, then verify findings in the actual files.

Pass each agent the full diff so it has the complete context. + +### Agent 1: Code Reuse Review + +For each change: + +1. Search for existing utilities and helpers that could replace newly written code. Use Grep to find similar patterns elsewhere in the codebase — common locations are utility directories, shared modules, and files adjacent to the changed ones. +2. Flag any new function that duplicates existing functionality. Suggest the existing function to use instead. +3. Flag any inline logic that could use an existing utility — hand-rolled string manipulation, manual path handling, custom environment checks, ad-hoc type guards, and similar patterns are common candidates. + +Note: This is a greenfield app, so focus on maximizing simplicity and don't worry about changing things to achieve it. + +### Agent 2: Code Quality Review + +Review the same changes for hacky patterns: + +1. Redundant state: state that duplicates existing state, cached values that could be derived, observers/effects that could be direct calls +2. Parameter sprawl: adding new parameters to a function instead of generalizing or restructuring existing ones +3. Copy-paste with slight variation: near-duplicate code blocks that should be unified with a shared abstraction +4. Leaky abstractions: exposing internal details that should be encapsulated, or breaking existing abstraction boundaries +5. Stringly-typed code: using raw strings where constants, enums (string unions), or branded types already exist in the codebase + +Note: This is a greenfield app, so be aggressive in optimizing quality. + +### Agent 3: Efficiency Review + +Review the same changes for efficiency: + +1. Unnecessary work: redundant computations, repeated file reads, duplicate network/API calls, N+1 patterns +2. Missed concurrency: independent operations run sequentially when they could run in parallel +3. Hot-path bloat: new blocking work added to startup or per-request/per-render hot paths +4. Unnecessary existence checks: pre-checking file/resource existence before operating (TOCTOU anti-pattern) — operate directly and handle the error +5. Memory: unbounded data structures, missing cleanup, event listener leaks +6. Overly broad operations: reading entire files when only a portion is needed, loading all items when filtering for one + +## Phase 3: Fix Issues + +Wait for all three agents to complete.
