Add baml cloud dashboard create, update, get and delete - #5620
baml cloud dashboard create|update|get|delete manages self-contained HTML dashboards using the saved Boundary login. Create rejects duplicate keys; update requires --expected-version and rejects concurrent changes. Get prints metadata JSON and optionally saves verified HTML with --output. Delete has its own permission independently of read.
Changes
The client sends management requests to the selected gateway, then transfers exact HTML using a capability restricted to one version and purpose. It keeps the login off storage requests, disables redirects, validates locations and expiry, verifies length and SHA-256, and bounds transfers by size and capability lifetime. Downloads replace the destination atomically with Unix mode 0600, preserving the old contents of any existing hard link. Project, endpoint and saved-login selection reuse existing configuration.
Testing
cargo test -p bcs_api: 56 passed.
cargo test -p baml_cli --lib: 463 passed locally.
Strict clippy for both crates and the CLI build.
Actual built CLI creates, gets metadata and exact HTML, updates, rejects a stale version, deletes, and reports a missing dashboard against a real test gateway; it verifies private output permissions and no login disclosure.
All CI jobs pass, including platform builds and tests. CodeRabbit approved the latest commit.
PR Checklist
Contribution guidance read; Rust changes stay in baml_language.
Style checks and self-review completed.
Non-obvious capability and private-file decisions are documented in code.
Command help and examples updated.
Tests and regression reproductions retained; no new warnings.
Additional Notes
Requires a gateway supporting native dashboard management. This is original wire-client code with no service implementation dependency.
The delayed-storage reproduction fails with a transport timeout without the bounded transfer timeout. The output-permission reproduction fails with mode 0644 instead of 0600 without private atomic replacement; it also proves an old hard link retains its original contents. Both regressions pass with the fixes.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.

Walkthrough
The CLI adds dashboard create, update, get, and delete commands. The API adds publication, retrieval, and deletion operations with session, capability, and transfer validation.
The API adds publication types and create/update operations. It validates sessions, capabilities, returned metadata, transfer size, and content hashes. Tests cover publication requests, upload credentials, timeouts, and rejected responses.
Dashboard retrieval and deletion baml_language/crates/bcs_api/src/dashboards.rs, baml_language/crates/bcs_api/src/dashboards/tests.rs
The API adds metadata retrieval, optional HTML download, and deletion. Tests cover retrieval modes, deletion requests, denied responses, invalid capabilities, and download integrity.
The CLI adds create, update, get, and delete commands. It resolves project and environment settings, dispatches API operations, and saves downloaded HTML through a temporary file. Tests cover command parsing, project selection, and file permissions.

Merge Risk: Minimal · up to 0c6a7
This change adds dashboard create, update, get, and delete commands with transfer validation. No actionable merge-blocking risk remains after the review.
Security architecture risk: Low · up to 0c6a7
The client separates login credentials from storage capabilities, rejects unsafe transfers, and verifies downloaded bundles before saving them. No client-side security regression was established. Dashboard authorization, capability scope, and concurrent-update guarantees still depend on server behavior that could not be verified.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The CLI addresses dashboards by cloud project, environment, and key, defaults the environment to production, and loads the saved login for the selected endpoint. Effective exposure depends on that session's server-side permissions; the client evidence does not establish a maximum authorized dashboard set or prove cross-project isolation.
Trust Boundaries and Controls
observed — Gateway requests carry the saved session; storage requests carry only the upload or read capability. The shared client disables redirects. Storage validation rejects malformed endpoints, non-loopback plain HTTP, HTTPS downgrade, invalid version-path identifiers, and locally expired capabilities before transfer.
inferred — The authenticated gateway remains a trust authority: it supplies storage destinations, opaque capabilities, and download integrity metadata. A malicious gateway can select another HTTPS destination, but it already receives the login credential. No separate lower-trust source controlling that destination was established. Server enforcement of capability purpose, version, expiry, and independent delete permission remains unverified.
Resilience and Maintainability Implications
observed — Transfer timeouts scale with advertised size and are capped by ten minutes and remaining capability lifetime. Download reads are bounded by metadata size plus one byte. Inspected mock tests cover credential separation, preparation denial without upload, malformed or expired capabilities, tampered downloads, and denial redaction; they do not verify production concurrency or authorization enforcement.
Hardening Proposals
proposed — Before rollout, validate the deployed gateway/storage contract for target authorization, independent delete permission, capability scope, atomic expected-version enforcement at commit, and cleanup or reconciliation after interrupted uploads and lost responses. These checks would close evidence gaps rather than remediate a verified client vulnerability.

- Around line 113-115: Update the dashboard upload PUT request at the
`.body(html).send()` chain to override the shared 30-second timeout with a
bounded timeout that allows transmission of the bundle based on its size while
never exceeding the upload capability’s expiry. Reuse the capability-expiry
information from the existing auth flow, and preserve the current request
behavior apart from the timeout.
