`SqliteWasmDriver` was already complete: its dialect steps every PRAGMA to the end (300 → 0 before and after this change).

On a file-backed database in WAL mode (the default) the database file shrinks once a checkpoint runs, and during the call the freed pages pass through the `-wal` file, which keeps its size until the last connection closes.

Nothing to migrate: `reclaimSpace()` keeps its signature, and a database whose `auto_vacuum` mode is not `INCREMENTAL` still reclaims nothing, as before.
`ComponentPropsMap` declares `action:button`, `action:group`, `action:menu`, `action:icon`, `element:definition-list` and `element:repeater` — six blocks in objectui's curated public vocabulary that had no row (#20371). Each row is strict from birth, with its key set measured from the objectui renderer's own read points at the `.objectui-sha` pin, not transcribed from objectui's `UIActionSchema`, the registrations' `inputs`, or this package's object-metadata `ActionSchema`.

Six new declared rows on a published surface, and two types the `element:` vocabulary now answers for, so the accept set a consumer writes against grows. Nothing previously accepted by a declared row is refused and nothing is retired.
10

11

What changes at the authoring doors (`os validate` / `os build` / `os lint`):
12
+
13
+
-**`element:definition-list` and `element:repeater` are no longer refused as `component-type-unknown`.** Both sit inside the reserved `element:` namespace; with no enum member and no row, the vocabulary refused them although objectui registers, publishes and offers both in the Studio page designer. They join the `element:` vocabulary through their rows (no enum member), and a typo inside the namespace (`element:repeatr`) is still refused.
14
+
-**The props gate now judges all six.** The four `action:*` types sat outside every reserved namespace, so an authored `properties` bag on them was skipped — a misspelled key parsed, stored and did nothing. Findings stay at the gate's existing warning tier.
15
+
16
+
Measured decisions worth knowing when you author these blocks:
17
+
18
+
-**`action:button` / `action:icon`** — `name` is optional (the renderer reads `name ?? label`). The executor is `actionType`; `type` inside `properties` is refused with a rename to `actionType` (on a page component `type` is the component itself). `visible` / `disabled` take a boolean, a CEL string or a `{ dialect, source }` envelope. The legacy `enabled` fallback and the host-only `autoTrigger` flag are refused with a prescription. `action:icon` reads no `size`. `objectName` names the object the action acts on (forwarded to the runner; omitted, the action acts on the page's object).
19
+
-**`action:group` / `action:menu`** — `actions` is a LIST of action objects (a member's executor is its own `type`); a bare list of action names is refused. A member's `objectName` rides the member object; the containers themselves read no `objectName`. `action:group` reads no group-level `name`, so it is refused with a prescription. `variant` / `size` take the Button primitive's vocabulary; `primary` and `md` are accepted only on `action:button` (and `primary` on `action:icon`), where the renderer maps them.
20
+
-**`element:definition-list`** — `items` of strict `{ term, description? }`; `columns` is the NUMBER `1` or `2` (the string `'2'` renders one column and is refused).
21
+
-**`element:repeater`** — `object` is required; `filter` / `sort` take the family's one orthography (`ViewFilterRule[]`, `SortItem[]`); `fields` takes a field name or `{ field }` (an unrendered `label` is refused).
fix(driver-sql): `reclaimSpace()` returns the freed bytes from the SQLite `-wal` sidecar too, and never waits on another connection (#20426)

Clause-②: no

On a file-backed SQLite database in WAL mode, the default, `reclaimSpace()` returned the whole freelist but left the freed bytes in the `-wal` sidecar. At 25,754 free pages the database file went from 103,149,568 to 16,384 bytes while the `-wal` file went from 4,255,992 to 94,430,432 bytes, and it kept that size until the last connection closed. The lifecycle sweep calls this method after every sweep that deleted rows, and it reported the datasource as reclaimed.

+
11
+
On better-sqlite3 (`SqlDriver`, and `TursoDriver` in local mode) the vacuum now runs in chunks of a quarter of the connection's page cache, 1,000 pages at the default cache size, with a `PASSIVE` checkpoint after each chunk. One `TRUNCATE` checkpoint closes the call, taken with a busy timeout of 0, so it never waits on another connection. On the same database, file plus `-wal` goes from 107,405,560 to 16,384 bytes while the driver is still open.
12
+
13
+
When another connection holds a read transaction, the call still returns without waiting (47 to 66 ms measured; a `TRUNCATE` checkpoint that waits blocked the process for the connection's 5-second busy timeout). The pages are off the freelist, and their bytes leave the files at a later checkpoint. The call no longer grows the pair either: 107,405,560 bytes before and after, where the single statement grew it to 197,580,000.
14
+
15
+
A database in rollback-journal (`delete`) mode behaves as before. The remote `TursoDriver` route and `SqliteWasmDriver` are unchanged. Nothing to migrate: `reclaimSpace()` keeps its signature.
