feat(studio): fleet config panel — view + switch active fleet (ADR #19 A+B) - #26
Merged
Conversation
…A+B) The visible config surface the ADR #19 read model was missing: which fleet this Studio is managing, against which credential/account, and the ability to switch between fleets from the UI. - oab-mcp: new read-only `fleet_config` tool (9th tool) — lists the configured per-fleet bindings (name/cluster/region/profile/expected_principal) plus the config file path and default cluster. Server now retains the bindings path. Profiles are names, not secrets. Catalog test + module doc updated. - src-tauri: `fleet_config` bridge command (mirrors runtime_context). - console: FleetConfig view-model + Source method (Tauri + Mock fixture); a pure `fleetConfigHtml` renderer (one switchable button per fleet, empty state shows where to add bindings). Clicking a fleet re-points every read (roster + identity) at its cluster — the ADR "switch" step, which through oab-mcp's per-cluster binding changes the managing credential. 7 new render tests. Slice A (view) + B (switch) of the config panel. Editing (write-back to fleets.toml) is slice C, stacked on this. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Drafted by Orca (
ecs-claude) — flagging authorship (shared GitHub identity across the fleet).The config panel the ADR #19 read model was missing — surfaces "which fleet am I managing, against which account?" and lets the operator switch fleets from the UI. Slices A (view) + B (switch); editing (write-back) is slice C, stacked on this.
What:
oab-mcp— new read-onlyfleet_configtool (9th tool): lists the configured per-fleet bindings (name/cluster/region/profile/expected_principal) plus the config file path and default cluster. The server now retains the bindings path. Catalog test + module doc updated. Profiles are names, not secrets.src-tauri—fleet_configbridge command (mirrorsruntime_context).console—FleetConfigview-model + aSourcemethod (Tauri bridge + Mock fixture); a purefleetConfigHtmlrenderer: one switchable button per fleet, active fleet highlighted, and an empty state that shows where to add bindings (directly answers "I see no panel for config"). Clicking a fleet re-points every read (roster + identity) at its cluster — the ADR switch step, which throughoab-mcp's per-cluster binding changes the managing credential/account.Effect: with two fleets on different accounts in
fleets.toml, the panel lists both; clicking one switches the whole console (roster + identity panel) to that fleet's account — the "switch fleet → switch managing account" the ADR called for, now visible and one click.Verification (this runtime now has extended resources, so the Rust side was built locally too):
tsc --noEmitclean ·vitest21/21 (7 newfleetConfigHtmltests) ·vite buildOK.cargo check -p oab-mcpandcargo check --tests -p oab-mcpboth clean. Rust test execution is left to CI (build-test) — linking the oab-mcp test binary statically pulls the full aws-sdk and has previously exhausted this runtime's disk; the tests are pure (tools()/ JSON shape).Next (slice C): in-app editing of the bindings — a structured form + a format-preserving
toml_editwrite-back +RwLockhot-reload of the loaded bindings. Stacks on this.Relates to #19.
