#1381 landed the bar's horizontal position; this branch decides when it is
drawn. The e2e keeps both scenarios and the golden carries both palettes'
pointer-state readings alongside the new edge-offset lines.
Review findings from the first round:
- ui-settings renders its full-viewport panel as a fixed-position DESCENDANT
of the sidebar column, so `pointerleave` never fires when the pointer moves
onto it and the bars stayed drawn after it closed. Leaving is now decided
against the column's box from a document-level pointermove that exists only
while the bars are drawn; the element's own leave stays for the pointer that
leaves the window.
- The rebind gate judges the rule rather than each declaration, so a pair that
mixes `transparent` with an l2 hover no longer passes, and the elevation
half compares whole values instead of token shape.
- Hiding no longer exempts a sheet from the elevated-surface rebind check.
- The e2e polls the reveal before reading a colour for the golden, and pins
that a pointerless scroll draws no thumb.
$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.
The session list overflows after a handful of sessions, and its scrollbar
was drawn permanently in a column that is at rest most of the time.
SidebarRoot now tracks the pointer over the whole column and rebinds
ui-theme's scrollbar indirection pair to `transparent` while it is
outside, keeping the thumb for 2s after the pointer leaves so it does not
blink out on the way past. Rebinding colour leaves the list's
`scrollbar-gutter: stable` reservation in force, so revealing the bar
moves no row.
ui-theme's gate now states the widened contract: a rebind targets an -l2
token pair or `transparent`, and nothing else.
Both editors live in `ui-models` and list the same thing, so they now share
one row shape rather than diverging when #1368 lands: a bordered entry per
model, id and display name on the row, and the capacities behind the row's
own disclosure. The context window is joined there by the per-model output
cap the adapter just gained; both read a decimal K/M suffix.
The shared class names carry this file's token spellings, not that branch's.
`--dsw-alias-border-subtle`, `--dsw-alias-text-tertiary`, and
`--dsw-alias-text-primary` are undeclared, so they resolve to the light-mode
literals in their fallback slots — the defect this section was moved off. A
styles test now rejects any `--dsw-*` name the token sheet does not declare,
so the next editor to name one fails instead of shipping a light-only
surface.
The keystroke buffer is now per capacity field rather than per row, since a
row holds two of them.
A catalog entry may now carry its own `maxTokens`, matching the shape the
pi-ai adapter already exposes. Exact-model resolution prefers it over the
profile value, so capping one model no longer means capping the route.
Defaults are unchanged: an entry without a cap, and any unlisted
pass-through id, still resolve to the profile `maxTokens` (256,000), and the
shipped catalog keeps its context windows.
$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.
