The seam README states the JSON-shaped write boundary, watch-disposer
quiescence, async listener containment, and the drained teardown; the
provider README rewrites Behavior around the operation chain,
read-modify-write, writer lock, ready reconcile, and leaf-level YAML
diffs, and updates Known Limitations to the residual guarantees.
A new Agent Note records the round's decisions and supersedes the
original note's deferred-lockfile alternative (cross-linked in place).
Chinese counterparts updated pair-by-pair (three briefed minimal
updates, one whole-document translation); type-equiv, config, cordis,
and module-graph catalogs re-recorded.
sessionTitle.rename appends a user-source session/title event; onUserMessage
skips scheduling while a user title stands, and an explicit refresh is the
deliberate unpin (provider regeneration, or a re-derived fallback when no
provider is registered).
Add @deepseek-ai/dsh-host-directory-picker-auto, a node-half-only chooser
that samples the host situation once at boot (bind host via a new
httpServer.host getter, SSH markers, platform, DISPLAY/WAYLAND_DISPLAY)
and mounts the matching dual-face backend (-native or -browse) as a real
Loader entry in the in-memory root tree; the effect disposer removes it.
Entry-level mounting keeps the seam's one-row-swaps-both-faces invariant:
the client module table discovers the mounted backend's browser half
exactly as a config row's. apps/cli now composes -auto as its
directory-picker row; composing a backend row directly remains the pin.
Review round on #758.
bash.run() only promises to resolve for nonzero exits, timeouts, and aborts,
and bash.resolve() can reject on policy grounds, so either could escape the
serial agent/step listener and abort the model turn — contradicting the
plugin's documented failed-query no-op contract. Contain both and log a
warning instead; the location is optional context.
The Agent Note claimed an unchanged location suppresses the query. It does
not: only the interval floor is checked before the query, while change
suppression compares state the query returned. Corrected in both languages
and re-recorded the i18n pairs.
Conflicts were the parallel-edit set: packages/README group table (kept
master's session-title wording, re-added the settings row condensed),
doc-budgets AGENTS.md ceiling (took master's 1750), and regenerated
graph/catalog docs plus re-recorded translation pairs. packages/README.md
ceiling 845 -> 850: the table legitimately gained one row for the new
settings group and the row is already minimal.
Confirmed and fixed, each with a regression test that failed first:
- Concurrent update() lost patches (merge over one stale snapshot):
per-namespace serialized write queues; a failed write cannot poison
the queue for later writers.
- Fixed-name .tmp write followed planted symlinks and kept stale modes:
random-suffix sibling, exclusive-create (wx), 0600, cleanup on
failure, then rename.
- A throwing settings/updated listener escaped commit and permanently
wedged the provider reload chain (rejected refreshTask): commit now
contains listener failures (INVARIANT-coded errors still propagate),
async watcher rejections are adopted and contained
(watch callbacks are officially void | Promise<void>), and the
provider chains refreshes on a settled tail with an error log.
- No way to remove a user override: scope/service replace(section)
sets the user section wholesale; replace({}) re-inherits base and
schema defaults.
- The three-primitive provider contract did not hold (base never
called load()): the base Service.init loads and publishes once;
settings-local delegates via yield* super[Service.init]().
- Dispose did not quiesce: teardown flags closed, closes the watcher,
then awaits queued/in-flight reloads; closed is re-checked across
await points.
- Invariant now checks the authoritative relation with the seam's own
deepEqualJson: emitted next must equal settings.get(ns), and
next/prev must differ structurally (cosmokit dependency dropped).
- New docs/core-data-structures/settings.{md,zh.md} with type-equiv
blocks + manifest entries; catalog types moved from exemptions to
LINK_MAP; website page registered.
Both packages stay at per-file 100% coverage.
Two-package capability family mirroring session-persistence/:
- dsh-settings: abstract Settings service — namespace registry with
caller-fiber effect registrations, layered resolution (schema defaults
< composition base < user document), schemastery validation,
per-namespace deep-equal commit detection, and the settings/updated
event. Boot/registration validation fails loud; provider publishes
keep last-good per namespace.
- dsh-settings-local: settings.yaml/.json provider — resolveSpec
defaulting to $DSH_HOME/settings.yaml, chokidar hot reload,
content-equality self-write suppression, atomic 0600 tmp+rename
writes, comment-preserving YAML namespace patching.
Consumers register inside ctx.inject(['settings'], …), so every
composition works unchanged without a mounted provider. Real Loader +
Include composition test proves cordis.yml boot and external-edit hot
propagation; HMR disposal test proves registry cleanup. Both packages
hold per-file 100% coverage.
Doc budgets rise 1705→1710 (AGENTS.md) and 835→845 (packages/README.md):
one structural line per file for the new package group.
Agent Note: .agents/notes/implemented/architecture/2026-07-28-user-settings-seam.md
The aborted exit no longer awaits close (Node queues it behind any
in-flight read, chaining the departed caller back onto the very stall
the abort escaped) — the abandoned close's failure is swallowed, it has
no consumer. Symlink stat probes race the signal too, with a
per-candidate abort check between probes, so a stalled probe target
cannot keep a departed request alive. The deferred handle cleanup after
a lost opendir race now consumes its own close failure instead of
leaking it as an unhandled rejection.
Every filesystem await in the browse scan (opendir and each read) now
races the signal through raceAbort, so a stalled network open/read stops
with a departed caller and an already-aborted request rejects even for
an empty level; the abandoned settlement is swallowed and an abandoned
open that still mints a handle is closed, never leaked. apiproxy maps an
aborted listing to the cancelled wire code, matching pickDirectory and
command.execute, instead of reporting a false internal failure. The
fixture spec call sites gain the wire signal argument the previous
commit's static lane flagged.
capability.list gains an optional AbortSignal threaded from the RPC
carrier's request signal (the pickDirectory pattern): a disconnected or
timed-out caller stops the opendir loop instead of the scan outliving
its caller, and the abort surfaces as its own reason rather than a
directory-unreadable dressing. boundedInsert rejects a full window's
at-or-beyond-tail candidate on one comparison and binary-inserts
retained candidates, so an oversized level no longer pays a window scan
per dirent.
The browse level now streams through opendir into a name-sorted window of
maxEntries + 1 candidates (boundedInsert), so memory stays O(maxEntries)
no matter how many children a directory holds and enterability probing
touches only windowed candidates; a windowed broken symlink is not
backfilled since the eviction already marks the level truncated.
schemastery joins the package's runtime dependencies (the source launcher
and isolated installs failed to resolve the value import). The
folder-error dialog's Choose again goes inert while the flow hole is
empty, and the withdrawal effect also keys on the open transition, so a
flow can never open over a hole nobody serves.
