.html/.htm/.xhtml op previews (read / write / edit, non-error) gain a
Render/Raw toggle in the preview pane head: the render view loads the
SAVED file through the same /sidebar/html route the editor's html viewer
uses, so relative assets (./style.css, img/x.png) resolve inside the
route and a segmented read still renders the whole document (the route
serves the file, not the op snapshot — the file-trace-style srcDoc
approach would render a cut-off document whose scripts never run).
The frame is ALWAYS sandboxed (HTML_IFRAME_SANDBOX, moved to the shared
html-preview.ts module — opaque origin, no allow-same-origin, no
top-navigation) plus the route's CSP sandbox header as
defense-in-depth; unlike the editor viewer this surface has no
no-sandbox escape hatch. The contract is pinned by new sandbox-spec
tests on the extracted HtmlRenderPreview component and the pane toggle
(off by default; absent for non-html and error targets).
Locales: zh/en + all 19 shipped third-language overrides (key-set-equal
gate green). Typecheck + eslint clean; sandbox/redact/diff-rows/frontmatter
suites 36/36 green. The full-suite host-side failures (fs-operations /
pty smoke / git / install-powershell) are pre-existing on the base
branch (verified via stash) and unrelated.
- DiffPane.tsx: gate the redacted view on the computed `hit` (the unused-var
lint was the memo returning redactionHit: true unconditionally; now an
unredacted payload short-circuits like the toggle-off path, and only an
actual secret hit builds the masked copy)
- MarkdownHtml.tsx: drop the three dead imports (ComponentType,
lazyChunkComponent, MermaidMarkdownProps) left by the mermaid-lazy merge
Typecheck clean; eslint clean on both files; 39 targeted tests pass.
The changes-tab op previews replay read/write/edit payloads into the DOM
(diff rows, read rows, markdown reading mode, error text) — when the model
reads a credentials file, that plaintext must not land on screen or in
inspectable DOM. New display-only redaction layer, on by default with a
one-click pane toggle (persisted in localStorage):
- path layer: credential-shaped filenames (.env / *secret* / *credential* /
*token* / *api-key* / private keys...) mask whole files line-wise
- content layer: ordinary files mask only secret-shaped spans — secret
field assignments keep the field name (api_key: [REDACTED]), plus bare
token prefixes (sk- / AKIA / ghp_ / xox / ya29.), Bearer headers, and
PEM private-key block headers
- redacted payloads flow through the same viewOp shape into diff rows,
read rows, markdown reading mode, and error text
Known edge (documented in README): an unquoted mermaid node label
containing a redacted secret breaks the diagram and falls back to source;
workaround is quoting the label. Session data is untouched — this is
display-only and not a boundary against same-context malicious plugins.
Locales: zh/en dictionaries + all 19 shipped third-language overrides
(key-set-equal gate green). 9 new unit tests; typecheck clean; targeted
suites 40/40 green. The fs-operations failure is pre-existing on the base
branch (environment-dependent, verified via stash) and unrelated.
Documents containing mermaid fences now route through the editor preview chunk-resident renderer (splitMermaidBlocks detection + LazyMermaidMarkdown), so diagrams draw with zoom/pan instead of code blocks, while plain documents keep the byte-for-byte single MarkdownText pass. The lazy stub moves to a light mermaid-lazy.tsx module (re-exported from MarkdownHtml.tsx) so the core client bundle imports it without statically pulling DOMPurify/HTML analysis along. Typecheck, 4 affected suites (22 tests), and the full build pass.
Ports dsh-file-trace v0.2.1 highlight coverage into the shared diff engine: JS/TS module suffixes share the js/ts keyword lists; CSS gains its own config (slash-star block comments threaded across lines, hyphenated property words via a wider word charset, 120+ properties/selectors/at-rules); markup files gain markup comments plus common tags/attributes; GraphQL and JSONC/JSON5 map in. Previously css/scss/less had a wrong hash-comment config and html was plain CONFIG_LANG, so both effectively rendered uncolored.
The changes tab preview pane gains a Reading/Raw toggle for .md/.markdown/.mdx session ops (read, write, and edit alike). Reading mode renders the resulting document through the shared MarkdownText pass (the same stack as the editor preview): GFM tables with alignment, task lists, strikethrough, footnotes, math, and code fences, with local image destinations rewritten through the session-scoped /sidebar/file media route (rewriteLocalImageUrls). Content sources: read -> parseReadContent (envelope stripped, blank lines preserved — markdown block structure depends on them, which parseReadLines drops); write -> the written content; edit -> the reconstructed resulting document from the in-window prior content when known, else the new snippet. Ported from dsh-file-trace v0.2.0 (PR #471 lineage), re-based onto the unified changes tab (#475) and the repo shared-renderer conventions (markdownTextProps labels contract, skin tokens, 21-dictionary locale parity).
