Second review round escalated the wrap-width divergence from a separate concern to a defect in this fix's own premise, and it is right. Only .input scrolls, so only .input loses content width to a scrollbar that consumes layout space — what Windows and Firefox draw, and what the theme's global `::-webkit-scrollbar` width makes chromium treat as occupying space. A narrower .input wraps a long soft-wrapped draft onto more lines, so it grows taller, its scroll maximum exceeds the backdrop's, and the mirrored offset clamps below the caret. That is the same failure the trailing-line sentinel fixes, in the same direction, so deferring it would have shipped a fix that does not hold where users run a classic scrollbar. My first attempt to reproduce it found nothing and was wrong: the probe content was not wrap-sensitive. With varied-length words the effect is plain — the same draft laid out at 8px-apart widths differs by 2 to 5 lines, while at equal widths a textarea and a div agree exactly. The three layers now reserve the gutter together, in the shared metrics block that already exists to keep them symmetric. `overflow: hidden` is still a scroll container, so the non-scrolling layers honour it: 8px is reserved on each, measured. The cost is a text column 8px narrower on every platform, which is the price of one geometry rather than a per-platform one. The browser scenario asserts the premise directly — equal wrap widths, and a reserved band greater than zero on each layer. The band is what stops the assertion being vacuous: the widths would also match with no reservation at all on this engine's overlay scrollbar, and it is the reservation, not the match, that carries the guarantee to a platform whose scrollbar takes real width. Removing the declaration fails it with `expected 0 to be greater than 0`, and fails the golden with it. Also from the same round, three comment corrections: the e2e file header no longer describes the deleted layout effect, the measurement guard no longer claims the backdrop holds exactly one text node (the sentinel makes a second), and the sentinel comment now carries the one-sidedness argument that also settles the ghost hint — the mirror only fails when the backdrop is SHORTER, and the hint can only add content, never remove a line box.
Packages
English | 中文
Packages use the @deepseek-ai/dsh-* scope. Each is a Cordis Service subclass or function plugin; contributions use ctx.effect(), ctx.on(), or ctx.waterfall(). Authoring rules: package and root.
Hierarchy
Packages live at packages/<group>/<pkg>/; groups are containers, while names remain @deepseek-ai/dsh-<pkg>. Each group README is the canonical package/ctx-key map.

Dependencies
The dependency graph is generated: docs/module-graph.md (pnpm run gen-module-graph, freshness-gated in CI).
Extension plugins depend on interfaces, never the concrete loop. dsh-agent-loop is swappable; UI, hook, and tool plugins use dsh-agent. Composition bundles, including dsh-agent-spine-demo, may depend on spine plugins. Capabilities split into interface / implementation / consumer packages; see capability seams.
Package READMEs cover purpose, APIs, extension points, and Model Experience unless on the model-agnostic omission allowlist. They also carry ## Known Limitations and Deferred Work or use its allowlist.
