Tokens could only be read from an environment variable or Google Cloud Secret Manager. Environment variables are fixed at container start, so short-lived credentials such as GitHub App installation tokens (1h expiry) could not be rotated outside GCP without restarting Sourcebot. Add two Token shapes: - `file`: reads the file on every resolve, so rotated mounted secrets (Kubernetes Secret volumes, CSI driver, token-minting sidecars) are picked up on the next sync. - `azureKeyVaultSecret`: fetches the secret (latest version unless one is pinned) using DefaultAzureCredential. Clients are cached per vault; secret values are not. Fixes sourcebot-dev#1704 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Priority: ➖ Normal Estimated code review effort: 3 (Moderate) | ~25 minutes Change: Feature · Severity of issue fixed: Medium Suggested reviewers: Merge Risk: 🔵 Low · up to The new token sources have a bounded configuration inconsistency: Azure endpoints are accepted more broadly than documented. Align validation and documentation; no material security or availability failure is established. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The new sources support credential rotation, but Azure endpoint validation permits HTTPS hosts outside the documented Key Vault domain. The demonstrated exposure depends on control of deployment configuration; public attacker access and credential disclosure are not established. Rotation also applies when credentials are resolved, not necessarily to already-initialized clients. Retained concerns

Enforce the documented Azure Key Vault host contract.
The schema says the identifier must use a .vault.azure.net host, but crypto.ts accepts any HTTPS host and passes it to SecretClient. This is a configuration-contract mismatch, not an established SSRF path because the inspected configuration path is trusted. Enforce the documented host, or update the schema and documentation if approved alternate endpoints are supported.

Tokencould only be read from an environment variable or Google Cloud Secret Manager. Environment variables are fixed when the container starts, so short-lived credentials can't be rotated outside GCP without restarting Sourcebot. GitHub App installation tokens (ghs_) are the main example: they expire every hour.Sourcebot already resolves tokens again on every use.

Note
Medium Risk
Touches secret resolution used by connections and auth; misconfigured paths or vault access could break syncs, but changes are additive and existing token shapes are unchanged.
Overview
Adds
fileandazureKeyVaultSecretas config token sources alongsideenvandgoogleCloudSecret, so credentials that change at runtime (e.g. hourly GitHub App installation tokens) can be picked up on each resolve without restarting Sourcebot.getTokenFromConfignow reads a trimmed path on every call (no value cache) and fetches Key Vault secrets viaDefaultAzureCredential, withSecretClientcached per vault but secret values always re-fetched. Key Vault URLs are validated to the/secrets/collection before lookup.The shared
Tokenschema, regenerated v3 schema snippets/types, config docs (including rotation behavior vsenvironmentOverrides), and changelog are updated accordingly.@azure/identityand@azure/keyvault-secretsare added to@sourcebot/shared, with unit tests covering file rotation, Azure client reuse, and identifier validation.Reviewed by Cursor Bugbot for commit d7e9f31.
