Chinesezjc fdcb45b619 fix(web): bound the SGR state and follow real terminal widths
Nine findings, one critical. Terminal cases verified in a real terminal first.

CRITICAL: cells held the accumulated SGR history, so every state boundary
re-emitted the whole chain — output switching color without a full reset
emitted O(n^2) characters. Measured: 3200 such cells produced 25 MB, and the
reviewer's ~90 KB alternating-color case is well under bash's own output cap.
State is now a normalized record (foreground, background, attribute set) with
one canonical sequence per boundary, so the emitted text is linear in cells;
the 90 KB case parses in 36 ms. That also makes the attribute closers every
chalk-based tool writes actually close: `\x1b[1mbold\x1b[22mplain` leaves the
following write PLAIN, which a real terminal confirms.

Width follows emoji presentation, not the U+2600-U+27BF block: `A✓B` redrawn
with `XY` shows `XYB`, so the check every progress line writes is ONE column.
Taking the block as wide misaligned exactly the output this card exists for.

Writing over either half of a wide pair blanks the other, since a terminal
cannot leave one cell of a two-cell glyph standing.

`line\n\x1b[0m` does not end in a newline as a string yet its last parsed line
holds nothing visible, so the terminator check now reads the parsed lines — it
had added a blank row and inflated the collapse count.

A line with no cursor movement no longer builds a column buffer at all; only
its SGR is folded, so an `ls -R` or a 5k-line log allocates nothing per
character.

The `.terminalDescription` rule had been inserted into an existing grouped
selector, silently giving `.codeBody` description typography and changing its
bottom margin from 4px to 0 — a pre-existing surface this PR does not own.
Split out, `.codeBody`'s margin restored.

Three comments contradicted their code: the fixture's exit-marker line (still
claiming recovery from a marker deliberately removed), `bash-sample`'s header
(still routing a click to the details panel, and calling the consumer's cap the
block's own), and a DetailsPanel comment stacked above the wrong rule. The
ui-primitives README documented only the CR/BS half of the replay, so a reader
would expect `OK0%` where `100%\r\x1b[KOK` renders `OK`.

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.

examples/ Demo bundles (agent-spine + TUI/CLI/ACP/JSON-RPC bins) leaves load Support — example infra
support/ Support infrastructure (testkits, invariants, replay, Loader smokes) Support — lower compatibility expectations
util/ Low-level zero-dependency utilities shared across groups (Branded<B>, Harness home/path helpers, timeout, retention) Support — small, stable, harness-dep-free

Groups distinguish product API from support infrastructure. New packages join an existing group; a new group updates its README and this table.

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.
