The new default's whole claim is that a launcher configuring nothing still
finds a person's presets, and nothing asserted it through a real composition —
`user-root.spec.ts` plugs the service directly, and every other lane pins
`includeUserRoot: false` so the machine's home cannot decide a golden.
This lane boots the real base and web-app bundles with only the shipped root
patched in, points `$DSH_HOME` at a temp home before boot (the derived root is
resolved when the plugin is constructed), and asserts a preset placed there is
listed as `user`, reported healthy, authorable, and mountable into an agent
whose tool catalog it decides.
The service moved its "is a roster composed" reads to the derived root set;
the invariant companion still read `config.roots`. In the shape this change
exists for — an app configures nothing and the roster is the harness home
alone — that made the advisory warning fire while the fail-loud invariant
stayed silent, so an agent could address a model against an empty global
layer unchecked.
Both now read one source: `roots` exposes the resolved set, and the invariant
asks it. That decides the behavior deliberately rather than by omission — a
composition that mounts the roster now fails an unjoined agent whether its
roots were configured or derived, and `includeUserRoot: false` with no
configured roots is how a deployment keeps its agents on the host plane. Both
shapes are pinned; the derived-only case fails against the old predicate.
Three pieces of prose went stale with the first commit: the web-app bundle
comment still called the writable root an assembly fact patched in by
AppCLIEntry (removed in the profile-plugin-bundles refactor — `composeProfile`
owns it now, and only for the shipped root), and the shipped skill and its
Agent Note still called both roots "configuration". The README gains the
resolved-roster reader and the discoverable-but-undeletable preset a second
writable root produces.
`Config.roots` defaulted to `[]`, so a deployment that did not patch both roots
in got a roster with none — `dsh run` once booted exactly that and failed
resolving `standard`. The user root never needed an app: `<dshHome>/.agent-presets`
is the same place in every deployment, resolvable here the way
`dsh-skill-local` resolves `<dshHome>/skills`.
The roster now derives that root itself unless `includeUserRoot` is false, and
`apps/cli` supplies only the SHIPPED root, whose path an installed app alone
can resolve. The derived root is appended after every configured root, so a
shipped id still shadows a home directory claiming it and `writableRoot()`
still prefers an explicitly configured `user` root; the set is resolved once at
construction, because a root set that changed between a `list()` and the
`copy()` acting on its answer would author into a directory the caller never
saw.
Every test that pins an exact roster now says `includeUserRoot: false` — the
machine's real harness home must not decide what a golden or an assertion
counts.
The rewritten test tolerated the interleaving where a fast command
settles before the running turn's next pre-step claim. The notice is
then folded into a step whose scripted reply is final, the turn closes
with an empty next-step inbox, and the collection entries are never
reached — a real timeout, not a tolerated ordering.
The command now blocks on a sentinel the test creates only after the
agent has gone idle, so the wake is the only path that can deliver the
notice, and the test asserts exactly two turns.
Also apply the review's smaller points: key the wake budget by Agent
rather than object, register the budget-refill listener only under
wakeup delivery, pin the schema default and rejection like
reportDelivery does, record the retirement-window stranding as a Known
Limitation, and cross-link the partial supersession both ways.
A throwing producer cancel jumped to the force-fail branch before
`reported` was set, so `settle()` announced an unreported completion and
the default wakeup delivery started a model turn on an owner the host
was already destroying — the exact failure mode marking the record
reported exists to prevent.
Teardown claims the report before calling the producer, because that
decision does not depend on whether the producer's cancel succeeds.
Also reject a `maxConsecutiveWakes` that cannot bound anything: the
field exists to cap a runaway chain, and `Infinity` removed the cap
while a fraction never named a turn.
Correct the module JSDoc and the background-task runtime note, both of
which still promised that notices never wake an idle agent.
The web-app overlay now disables the host tool-pwsh row too, and the shipped
presets (standard/code/cordis) declare both shell tool rows with inverted
platform gates — tool-bash on POSIX, tool-pwsh on win32 — so the preset layer
exposes exactly one shell tool per host and a preset can drop or replace the
shell tool on either platform. windows-shell.spec pins both preset gates and
both host tool rows disabled in the web composition; the loader and Windows
pwsh notes are updated in place.
The previous pass over-corrected: presenting both roots as unknowable made the
guidance vaguer without making it truer. Every `dsh` launcher puts authored
presets under `$DSH_HOME/.agent-presets`, so the skill and persona state that
as the answer to "where do my presets live" and reserve the read-back for the
path an agent actually opens or edits, which `copy()` already reports.
Neither root is a property of the preset layer. `Config.roots` defaults to `[]`;
the two the shipped agent sees are patched in by the dsh CLI, whose user root is
`dshHomePath('.agent-presets')` and whose system root ships beside the install.
`writableRoot()` then takes the first `user` root from whatever configuration
supplied it.
The skill and the persona stated `${DSH_HOME:-$HOME/.dsh}/.agent-presets/<id>/`
as where authored presets live, which is only the default install's answer, and
no call reports either root: `authorable` says whether a writable one exists,
and `list()` cannot reveal a user root that is still empty. Both now keep that
path as what to tell a user asking where to look, and direct every path an agent
acts on to `list()` or `resolve()` — which is also what `copy()` already relies
on, since it chooses the writable root itself and reports the file it created.
