Every registry value is a thunk — `() => import("../commands/x.ts")` with the path spelled out literally — not an eagerly-evaluated namespace import. That's what keeps `rt --version` and every other dispatch from paying for the whole command surface: the bundler still statically discovers all 30 modules, but none of them evaluate until a command actually dispatches to it. Adding a static (non-thunked) `import` of a command module to `lib/module-registry.ts`, or a static value import of `lib/rt-render.tsx`/`ink` to `lib/command-tree.ts`, is a startup regression — `scripts/bench-startup.ts` gates this in the release workflow (`.github/workflows/release.yml`), and `lib/__tests__/no-eager-tui.test.ts` gates the command-tree and command-module cases directly.

### `SCHEMA_VERSION` is claimed across sessions, not chosen per branch

Several agents work this repo at once, and `runMigrations` only replays when
`user_version < SCHEMA_VERSION`. So the first branch whose daemon opens
`~/.mattstack/rt/state.db` stamps the new number, and every *other* branch's
schema for that same number then silently never applies — its tables are
simply absent on that machine, with no error anywhere. This has already
happened once: two lanes both wrote a v4, one lane's daemon migrated the
real db minutes before the other merged, and the second lane's tables
never appeared.

Announce the version you are taking to the other sessions before you merge,
and renumber if you are second. To repair a db stamped by a schema that is
not the one on disk: stop the daemon, `PRAGMA user_version = <the previous
version>`, start it, and diff `sqlite_master` before and after to confirm
the other lane's tables survived (the replay is IF NOT EXISTS, so it is
data-preserving).

Prevent the repair from re-running legacy imports.

If <the previous version> is 0, runMigrations calls each registered legacy importer. The branch-cache importer uses an upsert, so stale JSON can overwrite current branch_cache rows. Restrict the documented repair to versions greater than 0, or provide a DDL-only path that skips legacy imports.

In `@CLAUDE.md` around lines 108 - 113, Update the documented database repair
procedure to avoid invoking legacy importers: require the previous schema
version to be greater than 0, or specify a DDL-only migration path that skips
legacy imports such as the branch-cache importer.


**Nothing but `IF NOT EXISTS` statements may appear in a `V*_SCHEMA` block.**
The runner execs `V1 + … + Vn` as one statement on *every* bump, so an
`ALTER TABLE … ADD COLUMN` that succeeded once throws `duplicate column
name` on the next bump, rolls the migration back, and makes every later
`openStateDb` call throw. Add a column by creating the table with it
(`IF NOT EXISTS`), or guard the add behind a `PRAGMA table_info` check.

Clarify the column-migration boundary

If an existing table needs a new column, do not add it only to CREATE TABLE IF NOT EXISTS. SQLite leaves the existing schema unchanged. Document a guarded ALTER TABLE outside the concatenated V*_SCHEMA string, or an explicit table-rebuild migration.

In `@CLAUDE.md` around lines 115 - 120, Clarify the V*_SCHEMA migration guidance:
keep only idempotent IF NOT EXISTS statements inside concatenated schema blocks,
and document that columns added to existing tables require a guarded ALTER TABLE

tables.


### Publishing `@mattstack/rt-client` is release-class, from `main` only

`0.5.0` reached npm with fresh `.d.ts` files over a stale `index.js`: its
types promised verbs its runtime bundle did not contain, so consumers
type-checked and then got `undefined` at call time. Publish only from a
checkout on `main`, never from a branch, never with `--ignore-scripts`
(`prepack` is what rebuilds `dist/`), and grep the built bundle for your own
verbs before you publish. The package version is a shared resource like
`SCHEMA_VERSION`: announce the bump, and let whoever merges second renumber.

### `packages/rt-client/dist/` goes stale without warning

`dist/` is gitignored, but `file:` consumers (mr-board, gitq, the console) copy it **verbatim** at install time rather than building from source. So any change or merge that touches rt-client's source leaves every consumer installing the previous build — the source is right, the shipped artifact is not, and nothing about the working tree looks wrong. Run `bun run build` in `packages/rt-client` after touching it, and after any merge that does.
