A fast one-shot can request exit through ctx.appExit while the launcher
still awaits its watcher setup; the failure guard now also swallows the
resulting rejections when the tree is no longer live, not only on
signal shutdown. Sync the app-boot README and headless bundle comment
with unconditional patch watching, and bring the two Agent Notes still
asserting the --dev row append and the headlessIo slot current.
The client-hmr row joins the web bundle as an ordinary always-on roster
row: without a rebuild watcher rewriting client bundles it polls
unchanged files and stays idle. This deletes the --dev flag, the web
runtime's mode config, the mode-forked prompt contract, the DSH_WEB_MODE
bash variable, and the post-settlement row-creation machinery the
conditional row required. dsh web + pnpm run dev:web remains the
development loop.
The whole-tree name scan (entries() recurses into subtrees) already
skips creation when any patch layer carries the row, including a
disabled one; make that contract explicit in the comment, pin it with a
test, and record it in the Agent Note.
The web runtime creates its dev-mode client-hmr row in the root tree
after Loader settlement with plain loader.create, deleting the vendored
Entry.enableRuntime state machine and dsh-cmdline's enableRow export.
Include declares the existing EntryGroup.key tree-carrier marker instead
of the EntryConfigResolver protocol (its own path stays literal; nothing
used a dynamic path). The launcher recognizes no app row: SIGTERM exits
0 on every surface, every boot watches its user patch layers, and the
headless runner exits through ctx.appExit, deleting ctx.headlessIo. Also
restores the vendor README rescope entry to the position the
rescope-vendor exact-edit anchor requires, fixing the master hygiene
regression.
Replaces the patch round trip. An app's entrypoint resolves the command
line into a service, and the rows it configures read that service from
their own config — port: !!js ctx.get('webStartup')?.port ?? 3080 — so the
resolved value beats the value written beside it and nothing is written
back into a row or handed to the launcher.
A bundle names the entrypoint row in its manifest (dsh.bundle.entrypoint),
which is what lets the boot mount in two passes: entrypoints alone, then
the whole composition. That ordering is required, not cosmetic — a row's
config expressions are evaluated when the include applies the row, and a
strict ctx.get only answers for a service whose providing fiber is already
active.
What this removes: ctx.appPatches and the launcher-owned patch layer, the
disable/re-enable recycle and its in-flight-mount barrier, overrideConfig,
and the reload hazard they existed for. A live config edit now re-applies
the second pass against services that are still up, so a served port
survives by construction.
What it adds: ctx.appReady, because Loader settlement no longer means the
app is up — a row mounted in the second pass can observe a settled tree
while that pass is still running, or already rolling back. The web URL line
waits for it, so a boot that fails in the second pass announces nothing.
The Agent Note keeps the three vendored-Loader facts the mechanism turns on
— a row's config is resolved and validated when its fiber is created, while
it is still waiting; an inject update loses the plugin's static injections;
a row cannot be inserted from inside a mounting plugin — with the
alternatives they ruled out.
Launcher flags come first and end at the first token dsh does not
recognize; everything after reaches the booted app verbatim, so
dsh --profile tui --resume <id> works with no launcher change and
dsh --profile web --help prints the web app's help. A bare dsh -h, which
has no app to hand the flag to, still prints the launcher's own.
src/web.ts is deleted: the Web flag family, its LAN-trust sampling, and the
one-shot task positional now live in their bundles, and runProfile no
longer knows any row id. What the startup row decides comes back as a
launcher-owned patch layer above every layer a user can edit, so a live
config edit recomposes the tree without resetting a served port.
dsh web and dsh --profile web finally boot through one path, which also
gives --profile web the harness-source prompt section that only the alias
used to add.
dsh-web-app owns --host/--port/--dev/--workspace-root/--trusted-host and
its --help in a web-startup row; the rows it configures wait for the
webStartup service, and the client-plugin HMR receiver now ships disabled
so --dev is a row toggle rather than a runtime insert (the Loader cannot
resolve a row inserted from inside a mounting plugin).
dsh-headless owns the task positional and rejects a missing task as its own
usage error. Its runner ships disabled, not merely waiting: the schema
requires the task, and a row's config is validated when its fiber is
created, before the startup row can supply one. A composition has exactly
one command-line owner, so the patch disables the web startup row and this
one provides webStartup too, leaving the web rows on their composed
one-shot values.
The keyless web scaffold provides the same three values with no arguments,
which is what an embedding host with no command line does.
A launcher provides three values before the tree mounts: ctx.cmdlineArgs
(get() is the whole interface) carrying everything after its own flags,
ctx.appExit for a bounded exit, and ctx.appPatches for decisions a later
recomposition must keep. An app's startup row injects cmdlineArgs and calls
runStartup() with its own commander program.
Rows the app configures inject its startup service, so they wait until the
startup row has resolved their values and provided it; --help prints,
disables those rows, and exits without the app ever starting.
A changed row is recycled — disabled, then re-enabled with its new values —
because a row's config is resolved when the Loader creates its fiber, while
the row is still waiting. Recycling never touches inject: an inject update
restarts the row from its unwrapped callback and loses the plugin's own
static injections. A mount still in flight is allowed to settle first, so
the disable has a fiber to dispose instead of racing one into existence.
