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.
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).
