The old $DSH_HOME/config.yaml personal overlay returns under the profile
scheme's filename: machine-local preferences that apply to every profile,
loaded after the profile's own cordis.patch.yml (so the home layer outranks
it) and before --patch overlays and flag patches. Both user layers are
hot-reloaded on long-lived surfaces and shown in --dump-config with their
own provenance labels; the built-bin e2e covers the home layer landing live.
- composeProfile keeps layers as bundle/user/overlay+flags segments instead
of one flat list later re-sliced by index arithmetic; the row index drops
the group-walk (profile trees are flat patch compositions) and the double
composition.
- The config dump anchors on the profile's real empty root (written by the
shared prepareProfile) instead of materializing a temp file, so dump and
boot compose over the identical base by construction.
- dsh-base drops its patchPath export: the dsh.patch manifest field is the
one contract; the package carries no runtime API.
- packageDirFromAnchor is paths-probe only (the require.resolve fast path
duplicated the probe's outcome); basename() replaces hand-rolled path
splitting; verify-cordis-config stops re-reading bundle manifests in-loop.
- Clone patch lists per generation (boot + composeLive): the include pushes
insert rows by reference and mutates them in place, so a reused object
baked user overrides into bundle rows and removal could not revert; the
built-bin hot-reload e2e now asserts an override AND its removal reverting.
- The headless runner awaits Loader settlement before prompting (its inject
gate covers only apiProxy/httpServer) and abandons cleanly when the tree
died during the wait.
- healProfilesModuleFallback walks the app's full dependency+peer closure:
out-of-tree plugins import seam packages (dsh-compact, dsh-subprocess, ...)
that only implementations reach, and peers are how seams are declared.
- Profile init writes pnpm-workspace.yaml (nodeLinker: hoisted), not .npmrc
— pnpm >=10 reads settings from the workspace manifest.
- Web dumps reject boot-only flags instead of printing a tree that differs
from the same invocation's boot; --port validates at the flag;
--dump-default-config no longer parses the (possibly broken) user layer;
trustedHosts flag derivation merges over the composed value instead of
replacing it; web-runtime gains surfaceContext (headless disables the GUI
prompt/bash-vars the old -p never mounted); 'node_modules' is a reserved
profile name; plugin-warning names the recovery step; client AGENTS.md
registration surfaces point at the web-app bundle.
- Ship session-reference/tmux-context/tool-ask-user as app dependencies for
terminal front-door patch layers (turtle-ui), same stance as mcp-client.
dsh --profile <name> replaces the fixed entry modes: --config and -p are
removed, --patch adds overlays over the composed profile, a positional task
selects one-shot mode (requires the headless-runner row), and dsh web stays as
the alias for --profile web carrying the Web flag family as patches. dsh
plugin --profile <name> forwards verbatim to pnpm in the profile directory,
initializes on first use, and reconciles the dsh.plugins layer list after
add/remove (patch-less packages warn and stay plain dependencies). Config
dumps and the keyless web e2e scaffold compose the same bundle layers over the
same empty root as the boot.
Profiles live at $DSH_HOME/profiles/<name>: a package.json with pnpm-managed
out-of-tree dependencies plus the ordered dsh.plugins bundle list, and a user
cordis.patch.yml layer. Bundles resolve installation-first, then
profile-local; composeEntries applies layers over an empty root through the
include's own applyEntryPatches; healProfilesModuleFallback maintains the flat
profiles/node_modules symlink surface so bare plugin names resolve from any
profile. The personal-overlay machinery ($DSH_HOME/config.yaml) is retargeted
to per-profile patch files: loadPersonalPatches becomes loadOptionalPatches
and watchPersonalPatches takes the exact filename.
Resuming a long session (196k events, 2.2k steps, 1.8k tool cards) took
~12s to render and ~800ms to echo one keystroke:
- Every step's timing footer called stepTimingAt, which replayed the whole
event log per footer - O(steps x events) on the initial render.
- pi-tui re-renders every component each frame and relies on per-component
line caches, but ToolCardComponent/ContextCardComponent built throwaway
Text/Markdown instances inside render(width), re-wrapping every settled
card's output on every keystroke.
Replace the per-footer replay with one shared StepTimingTracker per chat
mount (single O(events) cursor over the append-only log), and cache card
rows by width via CardLineCache, dropped by every state mutator and
invalidate().
Measured (tmux 200x50, 196k-event session): resume prompt-ready ~12s -> ~7.6s;
per-keystroke echo ~800ms median -> ~11ms.
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.
Rows no longer read logs for anything but the batch title fold: the
activity timestamp is a live session's last in-memory event time or the
artifact mtime via the optional sessionPersistence.locate(), falling
back to creation time; the last-turn, route, and goal columns are gone.
Route availability moves to the Enter-time preflight, which already
fully reads and replay-validates the one chosen log. The projectSessions
public API this PR had added to session-query is reverted — the change
is now confined to the TUI package.
TurnEndReasonMap.error now carries a single `error: LlmFailure` field:
an LlmError keeps its structured facts, any other error flattens to
errorChain text under the UNKNOWN code. Consumers read message/code
directly instead of defending against an unknown union — this also fixes
errorChain() rendering structured failures as '[object Object]' in the
TUI and ACP error paths. Document the turn-stopping contract: a
concludesTurn result never short-circuits already-submitted next-step
work (same-step additionalContexts or racing steering still runs), data
decides.
Steer, inject, and followup now land as durable user/message events on the
session surface; the steering/message event type and its ConversationNode
kind are removed from the client projection. Update tests, docs, generated
catalogs, and agent notes to match, and align the steering e2e fixture and
prompt inventory assertions with the durable user/message landing.
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).
CI caught a startup race the PTY smoke stages naturally: a TUI /exit typed
while watchPersonalPatches is still opening its watcher disposes the tree,
and the HMR effect registration rejects with INACTIVE_EFFECT, crashing an
app that exited exactly as asked. Return a no-op disposer for that exact
code; every other registration failure still propagates (covered both ways).
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
