design-platform.css declared four --dsw-alias-scrollbar-* tokens in both
palettes that no rule read, so every scrolling region rendered the user
agent's own scrollbar and the dark theme showed a light native bar against
dark surfaces.
The symptom that surfaced the gap was in the sidebar: the workspace
browser's session list is its only scrolling region, and each row's
trailing content (the relative timestamp, and the hover action buttons
that replace it) is `flex: none` flush against the row's 8px right
padding, so an overlaid scrollbar painted on top of the timestamp.
ui-theme/styles/scrollbar.css becomes the sole consumer of the four
tokens, imported by the web shell's base.css after design-platform.css
because it reads that sheet's tokens. The rules sit on `body`, not
`html`: the alias tokens are declared on `body`, custom properties
inherit only downward, and from `html` they resolve to the
guaranteed-invalid value with scrollbar-color computing to `auto`.
scrollbar-width and scrollbar-color are declared on `body, body *` rather
than inherited, because inheritance would carry the color already
substituted at `body` and an elevated surface could not retint its own
thumb; scrollbar-width does not inherit at all.
Both the standard properties and the ::-webkit-scrollbar pseudo-elements
read one indirection pair bound to the l1 tokens, so an elevated surface
rebinds that pair to the l2 tokens once and retints both renderings. The
command popup, slash menu, model-select panel, and settings panel do so,
which gives the l2 tokens their first consumers.
WorkspaceBrowser's `.list` declares scrollbar-gutter: stable, keeping the
bar beside the rows. `stable` rather than `auto` so the reservation holds
when the list is short enough not to scroll: expanding a workspace group
would otherwise shift every row sideways at the moment it starts
scrolling.
New zh pairs for the session-projection group and package READMEs (both
gained their missing language-switcher lines); the packages/README rows,
apiproxy README, and tool-todo README zh sides catch up with their edited
English; the group README's stale ProjectionProvider name becomes
ProjectionDefinition. RFC precision from review: asOfSeq is the last
event's seq (session.seq - 1, -1 empty; subscribed.lastSeq vocabulary) and
a new risk names the accepted dev-only staleness window when registry
churn changes the key set mid-session. Pairing re-recorded; 540 pairs
consistent.
gen-cordis-catalog type-link rows for the ProjectionDefinition surface and
CommandExecution; a sessionProjections service-role row for gen-doc-graphs;
regenerated module graph, persistence/config/cordis catalogs and api-catalog;
packages/README rows condensed back under the word ceiling; the RFC's sketch
fences marked ignore-check on both language sides (pairing re-recorded).
The rebase onto master picked up #585 (agent-loop message machine), which
removed the request-only session-prefix seam; the unified sourced-message
decision now owns the mechanism and the note's own banner declares the
seam removed. Archive the triplet and rewrite the skill-system note's
catalog mechanism against the shipped agent/step sourced injection,
keeping the archived note as the intentional historical citation.
Re-checked the other notes master added or amended (provider retry
policies, request-error retry action, observable state machine, OTel
telemetry, dependabot): their supersessions were already executed
upstream in the same PRs; no further active note qualifies.
