fa5eb17277 feat(studio): discriminated snippet union + source-aware writes (#48313)
Stacked on #48305.

## What

PR 3 of the stacked SQL-editor query-source series (Database vs Logs).
Stacked on the PR 2 branch `charislam/log-sql-content-shape`.

Turns `SnippetWithContent` into a discriminated union on `type` and
makes all snippet writes source-aware:

- `data/content/sql-folders-query.ts`: `SnippetWithContent` is now `{
type: 'sql'; content?: SqlSnippets.Content } | { type: 'log_sql';
content?: LogSqlSnippets.Content } | { type: 'report'; content?: never
}`. `report` is kept (the content endpoints' wire type carries it) but
has no SQL content — its body is `Dashboards.Content`, loaded through
the separate `Content` union.
- `setSql` brands per type (`untrustedLogSql` vs `untrustedSql`).
- `buildUpsertPayload` persists `snippet.type` (no longer hardcoded
`'sql'`).
- `createSqlSnippetSkeletonV2({ source })` emits the matching type +
content shape with the `as any` cast removed.
- New `components/interfaces/SQLEditor/querySource.ts`:
`SqlSnippetSource` + `getSnippetSource`.
- `seedSnippet` test helper gains a `source` arg.
- New `remapWireSnippet` boundary helper in `content-remap.ts`
concentrates the single wire->domain assertion, so `content-id-query` /
`content-upsert-mutation` call sites are cast-free (no `as unknown as`).
- Collateral: query result types aligned to the union; `updateSnippet`
no longer accepts `type` (source is immutable); db-only editor read
paths narrow away `log_sql`.

## Why

Impossible-states-impossible typing: a snippet's brand follows its
content type, so logs SQL and database SQL can never cross execution
paths. No behavior change for existing database snippets.

## Testing

- \`pnpm typecheck\` — clean
- \`pnpm --filter studio run lint:ratchet\` — no new warnings
- \`pnpm test:studio\` (data/content, SQLEditor, state/sql-editor) —
passing, including new tests for \`getSnippetSource\`, source-aware
\`setSql\`, type-aware \`buildUpsertPayload\`, and both skeleton shapes.

5db1137c56 fix(sql-editor): guard removeFavorite against missing snippet like addFavorite (#48111)
## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Bug fix

## What is the current behavior?

Fixes #48110

In the SQL editor Valtio store, `removeFavorite` guards against a
missing snippet with `if (storeSnippet.snippet)`, which reads `.snippet`
off `undefined` and throws `TypeError: Cannot read properties of
undefined (reading 'snippet')` whenever the id is not loaded in
`sqlEditorState.snippets`. Its counterpart `addFavorite` guards
correctly with `if (storeSnippet)` and no-ops on the same input.

## What is the new behavior?

`removeFavorite` now uses the same `if (storeSnippet)` guard as
`addFavorite`, so un-favoriting an id that is not in the store is a safe
no-op instead of a crash. Behavior for loaded snippets is unchanged.

Since `StateSnippet.snippet` is a required field, the old check was
always true whenever `storeSnippet` existed, so the only real world
difference between the two guards was the crash on the missing case.

I also added a small vitest file covering both methods (favorite set
plus needsSaving queued for loaded snippets, no-op for missing ids). The
missing-id test for `removeFavorite` fails with the exact TypeError
above when run against the old guard, and passes with this fix.

## Additional context

Root cause: `apps/studio/state/sql-editor/sql-editor-state.ts` line 260
(compare `removeFavorite` at lines 258 to 264 with `addFavorite` at
lines 250 to 256).

Gates run locally on top of current master (45ba40eff9): `pnpm
test:prettier`, `pnpm typecheck` (8/8 packages), `pnpm lint
--filter=studio` (0 errors), `pnpm test:studio` (only failure is
`lib/local-storage.test.ts`, which fails identically on clean master),
and `pnpm build --filter=studio`.

quick disclosure: I traced this one down and built the fix and test with
help from Claude Code, then verified everything locally myself. still a
college freshman finding my way around this codebase, so if the minimal
guard fix is not the direction you want (for example collapsing both
methods into one setFavorite), happy to rework it :)

1987f19d0a feat(sql-editor): add manual save feature preview (#47745)
## What

Adds an opt-in **SQL Editor manual save** feature preview that switches
the SQL Editor from autosaving every edit to saving only on demand, and
hardens the tab-close flow so unsaved edits are handled correctly.

## Changes

**Feature preview**
- New `sqlEditorManualSave` flag + `UI_PREVIEW_SQL_EDITOR_MANUAL_SAVE`
local-storage toggle, wired into the Feature Preview modal with an
explanatory panel.
- `useIsSqlEditorManualSaveEnabled` gates behavior on both the flag and
the user's preview opt-in.

**Editor toolbar**
- Save button (with `Cmd+S`) next to Run, plus an autosave status
indicator showing dirty/saving/saved state and a shortcut to disable
autosave (emits a `sql_editor_autosave_disable_clicked` telemetry
event).

**Discard on close**
- Closing a snippet tab with unsaved edits prompts for confirmation and,
on confirm, actually discards the local edits and evicts the cached
server copy so the snippet reopens clean.

**Decouple tab layout from SQL specifics**
- Tabs store gains a generic per-type close-handler registry
(`registerTabCloseHandler` / `getCloseConfirmation` / `closeTabs`). The
SQL editor registers its discard + confirmation behavior from the save
coordinator.
- Low-level `removeTab`/`removeTabs` (rename/move re-keying, stale
cleanup) intentionally do **not** trigger discard.
- Adds `statusOnDiscard` lifecycle transition and `clearSnippetContent`
store action.

## Testing
- `pnpm --filter=studio typecheck` — clean.
- Added unit tests for the close-handler registry (fires on single/multi
close, skips re-keying/cleanup removals, respects tab type, selects
confirmation copy, unregisters cleanly).

<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit

* **New Features**
* Added a SQL editor manual-save preview with a “Save” button and
`Cmd+S`, plus a modal option to disable manual-save/preview.
* Added “unsaved changes” tab status indication when manual-save is
enabled.
* Introduced tab-type-specific close confirmations (shown only when
needed).
* **Bug Fixes**
* In manual-save mode, closing a SQL tab with unsaved edits now clears
local snippet content and refreshes it on reopen.
* **Tests**
  * Added coverage for tab close handlers and confirmation behavior.
* **Chores**
* Added a persisted setting allowlist entry and tracked autosave-disable
clicks via telemetry.

7c1ea30e43 refactor(studio): extract useSnippetEditor from MonacoEditor (#47500)
## What

PR 7 of the SQL editor state re-layering stack. Extracts the snippet
editing lifecycle out of `MonacoEditor` into a co-located
`useSnippetEditor` hook, and consolidates the edit debounce.

`useSnippetEditor` owns:
- creating the snippet in the store on first edit and routing to its URL
(replace vs push for a `?content=` deep link)
- writing changes back to the store via `setSql` (with
`wasNeverPersisted` → `shouldInvalidate`)
- seeding the editor from the `content` param
- the read-only determination (`canEditSnippet`)

`MonacoEditor` now consumes `{ snippet, disableEdit, handleEditorChange
}` and keeps only the editor shell + Monaco action wiring. It sheds the
`router`/`profile`/`project`/`params`/store/tabs hooks.

`handleEditorChange` was also flattened with an early return.

## Debounce consolidation

Previously there were **two 1s debounces in series**: `useSnippetEditor`
debounced editor changes before writing to the store, and the save
mechanism (`createSaveMechanism`) already debounces persistence. That
added latency (up to ~2s to save) and split the "when to persist" timing
policy across two layers — at odds with PR 5's design where the
scheduler/mechanism owns *when* and dirty state is meant to be
immediate.

This PR removes the editor-side debounce: edits write to the store
synchronously on every change, and the save mechanism's 1s debounce is
the sole throttle. Net effects:
- the store — and the snippet's dirty status — reflects the latest edit
immediately (correct for the future manual-save mode's Save button / nav
guard)
- save fires ~1s after the *last* keystroke instead of up to ~2s
- only the active snippet's own reactive consumers (a lightweight
sidebar item) re-render per keystroke; Monaco is uncontrolled
(`defaultValue`) so it is unaffected

Note: the double-debounce was legacy (the pre-refactor god store had the
same `useDebounce(value, 1000)` in MonacoEditor plus a debounced
module-load subscribe).

## Notes

- Behavior-preserving in outcome — autosave still lands ~1s after typing
stops, just with lower latency and immediate store consistency.

## Validation

- `pnpm --filter studio typecheck` 
- `pnpm exec vitest --run state/sql-editor/`  (110 passed)
- lint  (0 errors; no ratcheted-rule regressions)

<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit

* **New Features**
* SQL editor changes now apply immediately, with unsaved status
reflected as soon as you edit.
* The editor now keeps the latest snippet details available for saving,
improving reliability when using “Save Query.”

* **Bug Fixes**
* Improved handling for creating and opening snippets from shared links
or prefilled content.
* Fixed status updates so saved snippets correctly switch to unsaved
after edits.

d153bab849 refactor(studio): extract SQL editor session store from god store (#47349)
## What

PR 6 of the SQL editor state re-layering stack. Moves ephemeral,
never-persisted SQL editor state out of the snippet/folder "god store".

**Session store** — `state/sql-editor/sql-editor-session-state.ts` holds
per-snippet, read-by-many session state:
- query `results`
- `explainResults`
- the row `limit`

…with their mutators (`addResult`/`addResultError`/`resetResult`,
`addExplainResult`/`addExplainResultError`/`resetExplainResult`,
`resetResults`, `setLimit`). `removeSnippet` drops a snippet's session
entries via `clearForSnippet(id)`.

**Diff-request slice** — `state/sql-editor/sql-editor-diff-request.ts`.
The Assistant's "Insert code" / "Replace code" diff is *not* per-snippet
session state: it's a transient, fire-and-forget command produced
outside the editor (e.g. query blocks / assistant) and consumed exactly
once by whichever editor is active. It's modeled as a consume-once
request (`requestDiff` / `consumeDiffRequest`) rather than durable state
— the editor drains it on apply, so a stale diff can't leak into a later
editor or session. (Previously this was `diffContent` in the god store:
never cleared and triggered by object-reference identity.)

Consumers read session state from `useSqlEditorSessionSnapshot` and the
diff channel from `useSqlEditorDiffRequestSnapshot`, keeping
`useSqlEditorV2StateSnapshot` only for snippets/folders.

### Why not the TanStack Query cache for results/explain?

Editor execution is a **mutation**, not a keyed query — `mutation.data`
is per-hook-instance and not keyed by snippet id, and there's no caching
value to capture (re-running SQL must return *fresh* data, never a
cached result). `EXPLAIN ANALYZE` actually executes the statement, so a
declarative/auto-refetching `useQuery` is semantically wrong.
Results/explain are imperative mutation outputs, scoped to the session,
read by several decoupled consumers keyed by snippet id — exactly what a
small in-memory keyed store models honestly.

## Consumers migrated

- `SQLEditor.tsx` — results/explain/limit reads +
`addResult`/`addResultError`/`addExplainResult`/`addExplainResultError`/`setLimit`;
diff-apply effect now drains a consume-once request
- `UtilityPanel.tsx`, `UtilityTabResults.tsx`, `UtilityTabExplain.tsx`,
`UtilityActions.tsx`
- `QueryBlock/EditQueryButton.tsx` — produces via `requestDiff`

## Notes

- Result/explain types are kept verbatim from the god store
(pre-existing `any` row/error types come along unchanged; tightening
them is out of scope for this move).
- `ref()` on result rows is preserved to avoid Valtio proxying large row
sets.

## Tests

- `sql-editor-session-state.test.ts` — result/explain mutators,
`resetResults`, `clearForSnippet`, `limit`
- `sql-editor-diff-request.test.ts` — `requestDiff`,
`consumeDiffRequest` (drain + queue-of-one)

Validation:
- `pnpm --filter studio typecheck` 
- `pnpm exec vitest --run state/sql-editor/`  (110 passed)
- lint  (no new errors)

## Summary by CodeRabbit

* **New Features**
* SQL editor query results, EXPLAIN output, and the “Limit results to”
setting now persist more reliably across a session.
* AI-assisted SQL insert/replace actions now use a pending diff workflow
to apply updates more consistently.

* **Bug Fixes**
* Results/EXPLAIN rendering and downloads stay in sync with the latest
executed data.
* Switching databases/snippets now clears the correct temporary results.
* Diff application is more resilient when an editor is still loading,
including empty-vs-non-empty editor cases.

* **Tests**
  * Added coverage for the session and diff-request state logic.

5cb81123ae refactor(studio): move SQL editor save trigger into a scheduler + provider (5/9) (#47316)
## What

PR 5 of a stacked refactor. Moves *when to save* out of a module-load
`subscribe` and into an injectable **scheduler** armed by a headless
**provider**, splits the save queue, and adds an unsaved-close warning.

### Scheduler (`sql-editor-save-scheduler.ts`)
`createSaveScheduler({ state, saveMechanism, notify, getSaveMode })`
owns the save *policy*:
- **auto** mode drains the dirty snippet queue as edits land; **manual**
mode (the seam for a future opt-in; defaults to `auto`) leaves snippets
queued until `requestSave`. Folder saves always drain.
- `start()` returns an unsubscribe; `requestSave(id)` is the
explicit-save entry.

### Provider (`sql-editor-save-coordinator.tsx`)
Headless `SqlEditorSaveCoordinatorProvider` instantiates the mechanism
(invalidation via the **React Query client from context**, not the
global `getQueryClient`) + scheduler, `start()`s it in an effect
(start/stop with the provider), and exposes `requestSave` via
`useSqlEditorSaveCoordinator()`. Mounted in `ProjectContext` (under the
app's QueryClientProvider). Cmd+S and the SavingIndicator Retry now go
through `requestSave`.

### Queue split
`needsSaving` (snippets) and `pendingFolderSaves` (folders) are separate
queues, drained independently — the old snippet-vs-folder `if/else` is
gone.

### Unsaved-close warning
A `beforeunload` guard triggers the browser's native "Leave site?"
prompt while any snippet's `status !== 'saved'` (failed / in-flight /
never-saved).

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->

## Summary by CodeRabbit

* **New Features**
* Improved SQL editor saving with a centralized save flow, including
automatic/manual save handling and immediate “Save Query” requests.
* Added unsaved-change detection so the app can warn before closing or
reloading when edits are still pending.

* **Bug Fixes**
* Retry actions now use the updated save flow for more reliable
re-saving.

16526bd6bf refactor(studio): extract SQL editor save mechanism + model folder lifecycle (4/9) (#47276)
## What

PR 4 of a stacked refactor of the SQL editor snippet/folder state. It
pulls the persistence logic out of the store into an injectable
mechanism, and replaces the folder `'new-folder'` id sentinel with an
explicit lifecycle — plus a concurrency bug fix that surfaced along the
way.

### Save mechanism (`sql-editor-save.ts`)

`createSaveMechanism({ state, upsertContent, createSQLSnippetFolder,
updateSQLSnippetFolder, invalidate, notify, debounceMs })` → `{
saveSnippet, createFolder, updateFolder }`. The store's subscribe now
dispatches to it; *when* to save still lives in the subscribe (the
scheduler/provider move is PR 5). Per-id debounce cache lives in the
factory closure (no module-global leak).

- **`saveSnippet`** reads the live store snippet, guards
`isLoadedSnippet` so a content-less snippet can **never PUT an empty
body** (directly unit-tested), then builds the payload + drives status
transitions + gated invalidation.
- **`toast` is injected** as a `Notifier` (new generic DI contract in
`lib/notifier.ts`) — the mechanism no longer imports sonner.
- **create vs rename are two named-arg functions**, not an `isNew`
branch; rollback is deterministic per operation instead of matching on
`error.message` text.
- **caught errors are `unknown`**, narrowed via the existing
`getErrorMessage` util with a generic fallback — no `any`.

### Folder lifecycle (replaces the `NEW_FOLDER_ID` sentinel)

- **`FolderStatus`** enum (`new_editing | new_saving | editing | saving
| idle`) collapses the persistence and progress axes into one enum —
same pattern as `SnippetStatus` — with `isNewFolder` / `isFolderEditing`
/ `isFolderSaving` predicates. Tagging a folder as new/persisted is now
an explicit field, not an id convention.
- New placeholders get a **unique local id** (`crypto.randomUUID`);
`NEW_FOLDER_ID` is deleted, which also lifts the accidental
one-unsaved-folder-at-a-time limit.

### Bug fix: folder-rename rollback race

The shared `lastUpdatedFolderName` field let two in-flight renames
clobber each other's rollback target (and a shared `finally` could wipe
it). Replaced by a **per-folder `previousName`** on
`StateSnippetFolder`, so concurrent renames of different folders are
isolated. A new test runs two failing renames concurrently and asserts
each restores its own previous name.

## Tests

`sql-editor-save.test.ts` (mechanism — fakes + fake timers, incl.
content-less no-PUT and concurrent-rename isolation) and
folder-lifecycle predicate tests. `pnpm --filter studio typecheck`
clean; 82 state/sql-editor unit tests pass.

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->

## Summary by CodeRabbit

* **New Features**
* Improved SQL editor folder handling with clearer create, rename, and
save states.
* Added a more consistent notification flow for successful and failed
save actions.

* **Bug Fixes**
* Improved rollback handling when folder renames fail, helping restore
the previous name reliably.
* Updated save behavior to better protect against duplicate or
out-of-order updates.

d5653f1f92 refactor(studio): unify snippet save + persistence into SnippetStatus (3/9) (#47251)
## What

PR 3 of a stacked refactor of the SQL editor snippet state. Replaces the
two overlapping pieces of snippet lifecycle state — the `savingStates`
map (`IDLE|UPDATING|UPDATING_FAILED`) and the `isNotSavedInDatabaseYet`
boolean — with a single `SnippetStatus` enum.

## Status is attached at the data layer (never absent)

- `SnippetStatus` + `SnippetWithContent` now live in `data/content`. The
snippet queries attach `status: 'saved'` via a typed `withSavedStatus()`
helper, and `upsertContent` returns `SnippetWithContent` so move/rename
responses carry status too.
- A SQL-typed `getSqlSnippetById`/`useSqlSnippetByIdQuery` returns
`SnippetWithContent` (the generic `useContentIdQuery` stays for Reports,
which use it). `[id].tsx` loads content with **no casting**.
- `'new'` is attached on local creation (`createSqlSnippetSkeletonV2`).

## Behavior

Behavior-preserving for the existing auto-save flow (faithful mapping of
both old fields, including the replication-lag swallow). One incidental
fix: the read-only/saving indicator now also covers a brand-new
snippet's first save (previously only re-saves of persisted snippets had
distinct saving/failed states in some paths).

## Tests

New `sql-editor-lifecycle.test.ts` (29 tests) covering every predicate
and transition; existing rules tests updated. `pnpm --filter studio
typecheck` clean; 52 state/sql-editor unit tests pass.

<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit

## Release Notes

* **Refactor**
* Restructured SQL snippet persistence tracking, replacing boolean flags
with a comprehensive status system for clearer visibility into save
progress.
* Enhanced saving indicator UI to reflect accurate snippet save states.

* **Tests**
* Added test coverage for snippet persistence state transitions and
lifecycle scenarios.

e1e2498db0 refactor(studio): extract SQL editor domain rules into pure module (2/9) (#47204)
## What

PR 2 of a stacked refactor of the SQL editor snippet state. **Stacked on
#47203 (PR 1)** — review/merge that first.

Extracts scattered business rules + the upsert-payload builder into a
new **pure** module `apps/studio/state/sql-editor/sql-editor-rules.ts`
(no Valtio, React, toast, or runtime data-layer imports):

- `canEditSnippet` — read-only rule (shared snippet you don't own), was
inline in `MonacoEditor` `disableEdit`
- `isSnippetOwner` — owner check, was inline in `ReadOnlyBadge` /
`SavingIndicator`
- `validateMoveToFolder` — 'shared snippet cannot be within a folder',
was a buried `toast.error`
- `buildUpsertPayload` — the PUT /content payload, was an inline object
literal (all `??` defaults preserved)
- `isLoadedSnippet` — type guard (see below)

## Bug fix: no more empty-content saves (and no non-null assertion)

The old payload builder used `{ ...content!, content_id: id }`. Tracing
that `!` upstream surfaced a real bug: **favoriting a snippet from the
sidebar that had never been opened** enqueued a save with no loaded
content, producing a PUT with an empty content body (rejected by API).

The requirement that a persisted snippet has loaded content is now
enforced **at the type level** rather than by a runtime assertion or
comment:
- `buildUpsertPayload` accepts only a `LoadedSnippet` (content
non-nullable) — the `!` is gone.
- the save subscriber crosses that boundary via the `isLoadedSnippet`
type guard.
- the sidebar favorite toggle loads content first (mirroring
`onSelectDuplicate` / the share modals), narrowing the fetched union
content to the SQL variant via its discriminant — **no type cast**.

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->

## Summary by CodeRabbit

* **Bug Fixes**
* Improved consistency in read-only behavior and ownership checks across
the SQL editor by centralizing permission logic.
* Fixed favorite toggle to ensure snippet content is fully loaded before
persisting changes.

* **Refactor**
* Centralized SQL snippet permission rules and validation logic into a
dedicated helper module.

2b24065c7b refactor(studio): relocate SQL editor store into state/sql-editor/ with facade (1/9) (#47203)
## What

PR 1 of a stacked refactor that re-layers the SQL editor snippet state
(`apps/studio/state/sql-editor-v2.ts`). This first PR is a **pure
structural move with zero behavior change** — no consumer files are
touched.

- Relocates the Valtio store body into
`apps/studio/state/sql-editor/sql-editor-state.ts`
- Extracts the type declarations into
`apps/studio/state/sql-editor/types.ts`
- Adds `apps/studio/state/sql-editor/index.ts` as the public surface
- Keeps the old `apps/studio/state/sql-editor-v2.ts` path as a thin
re-export **facade**, so all existing importers keep working unchanged

## How to read the diff

`sql-editor/sql-editor-state.ts` (~507 lines) is the **verbatim
relocation** of the former `sql-editor-v2.ts` body — not new code. Git
does not show it as a rename because the old path is intentionally
retained as the facade. The only genuinely new lines are `types.ts`
(20), `index.ts` (8), and the facade itself (8).

## Why

The store has accreted four tangled responsibilities (snippet/folder
CRUD, query results, persistence, Assistant diff). The stack
incrementally splits these into pure rules, a persistent store, a
session store, and an injectable save mechanism whose trigger is a
swappable policy (setting up a future auto→manual save migration). Each
PR stays ≤300–400 non-test lines and behavior-preserving.

## Verification

- `pnpm --filter studio typecheck` passes (only pre-existing unrelated
module-resolution errors remain).
- Lint passes (no new errors).
- No consumer imports changed.

<!-- This is an auto-generated comment: release notes by coderabbit.ai

* **Refactor**
* Restructured SQL editor state management into a modular architecture
