$DSH_HOME/config.yaml was an implicit composition layer: if the file existed,
every launch applied an arbitrary Loader patch graph over the shipped tree,
kept live by a dedicated HMR watcher. Three costs came from the implicitness,
not the capability. A patch replaces its target row's whole config, so a file
written months ago pins that row to the field set it knew and every default
the shipped tree later adds silently stops applying. It competed with the
typed settings namespaces llm-deepseek and llm-pi-ai already register, so
which one wins was a function of layer order rather than meaning. And the
explicit escape hatch it was supposedly redundant with did not exist on every
surface: dsh -p, dsh meta, and dsh upgrade all rejected --config, so for them
the implicit file was the only composition route at all.
Complete the explicit layer first: --config and --config-replace now work on
every booting surface. A headless --config-replace tree must still mount a
webserver row, because that surface reaches its own agent over the same HTTP
gateway the browser uses; AppCLIEntry names that contract in the failure
instead of reporting a bare missing service.
Then delete the implicit one. PERSONAL_CONFIG_FILENAME, loadPersonalPatches,
watchPersonalPatches, and the config-only HMR row mounted for it are gone; a
file left at that path is inert, and --dump-config no longer reads the Harness
home. --config therefore stops *replacing* the personal overlay and simply
*is* the user overlay.
No migration: a user who wants the old behavior names the same file
(dsh --config ~/.dsh/config.yaml), which a shell alias makes permanent.
$DSH_HOME/.env carried two incompatible jobs. As credentials-local's writable
secret store it could not be hoisted into process.env — hoisting makes every
stored key read as a read-only launch override and blocks rotation from the
TUI and the web page. But its name and dotenv format promise an environment
file, so a DEEPSEEK_BASE_URL sitting beside a working DEEPSEEK_API_KEY in the
same file was silently ignored: only the credential provider read the
document, and it addresses credential references alone.
Split the two jobs into two files.
.credentials.yaml is the provider-managed store: a strict YAML mapping of
CredentialRef to non-empty string, no version field, no wrapper level. Because
it holds credentials and nothing else, a non-mapping root, a non-identifier
key, a non-string value, an empty string, a duplicate key, and malformed YAML
are all rejections rather than skipped entries — loud at boot and at a write,
warn-and-keep-last-good on a live reload. The dotenv physical-line editor
gives way to a patch of the parsed document, so comments and untouched entries
keep their formatting and any string value round-trips, multi-line included.
Writer lock, read-modify-write, atomic 0600 write under a 0700 directory,
watcher, self-write suppression, and quiescent disposal are unchanged.
$DSH_HOME/.env becomes the user's ordinary environment layer. app-boot's new
loadLayeredEnv loads the invoking directory's .env then the Harness home's,
giving user < project < inherited; the home resolves from the inherited
environment first, so a project .env cannot redirect it.
Credential precedence is unchanged: the live environment still wins read-only
over the file, and shadowed writes still reject. Whether a provider-managed
store should instead win over the environment is a separate decision.
No migration: a key already in $DSH_HOME/.env keeps resolving through the new
environment layer, as a read-only env source that shadows the stored one.
`./.dsh-tmp-profile/config.json` was the web config-tree boot's user-config
plane, but never gained a writer: no production code created or edited it, no
test exercised it, and no user documentation named it. The fields it mapped
have owners elsewhere — provider/model are the api-gateway's default route and
persistenceRoot is an assembly fact, while typed user preferences live in
$DSH_HOME/settings.yaml.
Delete PROFILE_DIR, PROFILE_FILE, ProfileMapping, PROFILE_MAPPINGS, and
readProfile() with the patch source that consumed them. AppCLIEntry now
composes patches from CLI flags and the resolved frontend distIndex only; the
surrounding layers are unchanged. A file on disk is ignored completely — no
migration, replacement format, or deprecation diagnostic, per the pre-release
stance.
session-title already registers a title projection unit; /resume now
reads it instead of scanning logs: live rows from the registry
snapshot, persisted rows from the durable checkpoint row
(cachedSnapshot, zero I/O), and only rows without a usable checkpoint
pay a coldSnapshot — checkpoint plus readFrom tail, written back so the
next scan is metadata-only. Cold reads are bounded by the new
resumeScanConcurrency config; compositions without the cache fall back
to the bounded readTitleSnapshots batch. The TUI overlay mounts the
projection registry, storage, and projection-cache rows over the same
storages root the web surface uses, so checkpoints serve both.
- turn boundary now returns false for an empty admitted batch (claimed
input removed before the wake) instead of opening a turn and spending a
model call on nothing; the step boundary already had the symmetric guard.
- a max-token step stays sticky when steering or injected work continues
the turn: a later completed step no longer downgrades the outcome,
matching the TurnEndReasonMap contract.
- session/queue wire schema accepts the context placement (previously the
zod union rejected injected-context snapshots wholesale and the client
silently dropped the whole frame); schema tests cover all placements.
- headless runs settle at whole-agent idle instead of the first turn/end,
honoring the one-shot idle-to-idle contract.
- flush JSDoc names the real callers (checkpoint policy, goal-session,
teardown, self-flushing consumers); apiproxy zh README loses its stale
duplicate history section; ACP note/README record the delivered error
rejection and turnless-cancelled behaviors.
Master's transactional loader made the invalid-provider PTY case regress:
the HMR main watcher's initial scan refreshed the include mid-initial-apply,
the concurrent group updates stranded the include fiber, and once serialized
the failing apply's rollback deadlocked on HMR's refresh drain — dsh exited
13 with no diagnostic and the terminal stranded, the exact symptom this
branch fixes. Serialize every include child-tree mutation through one queue
and pass ignoreInitial to the HMR main watcher; the failing boot now settles
through boot()'s labelled rejection with the tree disposed and exit 1. The
PTY case asserts the settled diagnostic; the fail-loud release remains the
guard for rejections boot cannot see.
Conflicts: apps/cli/src/tui.ts (keep the release install over master's comment
rewording), packages/ui/app-boot/README* (master's new installFailLoud row
wording plus this branch's release and timeout rows).
The opt-in `core-web.cordis.yml` profile promises "exactly persistent
`bash` plus `str_replace_editor`" (its header comment and `apps/cli/
README.md`), but the base registration of `tool-subagent-list-agents`
(added with the durable child catalog) was not disabled by the overlay,
so the profile actually exposed `bash`, `str_replace_editor`, and
`list_agents`. The assembled snapshot was updated to accept the third
tool, which ratified the contract break instead of fixing it.
Disable `tool-subagent-list-agents` in the overlay and restore the
snapshot's expected tool registry to the documented two tools.
- Wire the control service and send_message tool into every shipped
composition with a resumable provider and background enabled
(headless-agent, tui-agent, and the SDK helper's subagent feature
base resources); jsonrpc-agent disables background and is unchanged.
- Resolve the send_message availability check in the CALLER's tool
scope so a restriction that removes the follow-up tool from one
agent also blocks that agent's continuable start.
- Control-service disposal now cancels live activations and awaits
producer settlement instead of stranding them: TaskService keeps
producer Tasks across a reload, so the disposing service aborts each
activation-owned controller, resolves its terminal gate (the
effect-scoped onTaskDone listener is already gone), and awaits done.
A new test kills a mid-start activation through HMR disposal.
The shipped-roster change made @deepseek-ai/dsh-tool-session-query a
default row of the shared base.cordis.yml, so the TUI and Web surfaces
put the five session-search tools in front of the model. That
contradicts the recorded opt-in stance for the model-facing session
query consumer; the ACP example remains the mounted reference.
Remove the row from the shared base, the now-dangling disabled patch in
the opt-in core-web profile, and the workspace dependency. The
ctx.sessionQuery index stays: the TUI's /resume and the Web content
search consume it directly. Both shipped-composition tests now pin the
20-tool catalog.
ds-review-bot round 1 on the DSH-home integration:
- generated wrappers now inject the services their manifest needs (skills/
tools beside loader), and loadPreparedRepository rejects a wrapper fiber
that settles anything but ACTIVE — a composition missing a required
service fails the repository transaction instead of committing an ACTIVE
row over a silently PENDING child (critical finding)
- the github: source ref segment excludes '#', so 'a#b' refs fail at the
config parser with the promised syntax instead of inside pnpm
- watchPersonalPatches re-reads the include's non-patch options per refresh
instead of a registration-time snapshot
- the TUI smoke's cache-seeded wrapper is produced by the real
prepareDshPlugin (cache LAYOUT stays a deliberate external pin)
- new Loader integration test drives a live repositories update through
entry.update: generation swap, old skills removed, failed candidate
rolled back to the previous generation
