feat(studio): edit fleets.toml in-app — CodeMirror TOML editor (ADR #19 C) - #30
Merged
Conversation
… C)
The edit half of the config panel: the operator edits the raw fleets.toml in a
CodeMirror TOML editor and saves; the change validates, persists, and hot-reloads
without a restart. Completes declare(edit) → switch → observe → reconcile.
- studio-cp: `read_bindings_text` / `write_bindings_atomic` (temp+rename) /
`save_bindings_text` — validate the text parses BEFORE writing (a bad edit
never lands on disk) and store bytes verbatim, so comments/layout survive with
no format-preserving lib. Unit tests: round-trip, reject-invalid-without-write,
missing-file-is-empty.
- oab-mcp: `fleet_config` now also returns the raw `text`; new write tool
`fleet_config_write { text }` validates + writes + hot-reloads (bindings moved
behind an RwLock; the per-cluster resolved-config memo is cleared on write).
Catalog is 10 tools.
- src-tauri: `fleet_config_write` bridge command.
- console: CodeMirror 6 TOML editor (StreamLanguage + legacy TOML mode) mounted
imperatively in a section separate from the re-rendered panel, so switching
fleets never wipes an open edit. "Edit config" opens it; Save calls the write
tool and surfaces a parse error inline; Cancel discards. 1 new render test.
Slice C of the config panel, stacked on the A+B view/switch slice. Editing is
raw-text (operator chose a TOML editor over a structured form).

fleets.tomlvia a CodeMirror TOML editor. Supersedes #27, which GitHub auto-closed when its stacked base branch (feat/fleet-config-panel, #26) was squash-merged into main. Same commit, rebased onto current main (now carries #26 A+B and #28's ServiceNotFound fix).What:
