v0.1.0

Added

• Grouped bar and line charts. chart takes seriesNames plus one values array per item: {seriesNames: ["修前","修后"], data: [{label:"图边", values:[13,41]}]} draws one group of two bars per metric, with a legend. A before/after comparison had no way to be expressed, so it was flattened into one bar per metric-and-time with the time tag concatenated into the label — which stops being a comparison.
• Closing-turn channel (the figure no longer depends on the model remembering). agent/turn-stopping now runs the same structure check the nudge uses: when a drawing session tries to close on an answer that carries structure (a table, five-plus list items, or comparison/plan/flow prose) and no figure, the plugin steers the agent, which re-opens the inbox so the model owes another step and draws the figure. Capped at two steers per session with a two-turn gap, so it cannot loop. Measured cause: an AnGIneer session drew 12 figures over 29 turns while individual answers shipped tables, and the old rate-only rule stayed silent for all 29 turns — the model's own reasoning said "I already drew 9 figures, I'll use a table here".
• Guidance runs as a procedure, not a preference: plan the structures first, make the draw_figure calls in the same batch, write the answer around the figures, then self-check the prepared answer for a table or long list that should have been a figure.
• raster-diagnostic.txt in the session workspace records every raster degradation where the user can read it, plus a session figure-coverage line in the tool result (figures embedded in replies versus figures drawn).

Fixed

• An asymmetric before/after chart is refused with the fix in the message. A chart whose label pairs a metric with 修后 but not 修前 (or the reverse) is not a comparison, and the missing half silently drops a number the answer's own table carries. The validator names the group, the missing side, and the grouped spec to send instead. Measured case: a chart shipped 进图轮次 修前/修后, 图节点 修前/修后, 图边 修后 while the same answer's table read "图规模 5 节点/13 边 → 24 节点/41 边" — the 图边 修前 value 13 was lost.
• The closing channel is gated on the session's own shape. It arms only in a session that has drawn at least once; the cheap reminder channel only in a session that has already produced a structured answer. Without that gate a working session (code, commits, verification logs) would be steered into drawing figures it does not need, at one extra model step each time.
• A raster failure no longer produces a broken image. The GUI serves figure files with Content-Security-Policy: sandbox; default-src 'none', and Chromium refuses to rasterize an SVG loaded that way — so falling back to a relative .svg link (option A's documented fallback) rendered nothing at all. Measured live in the DSH Web GUI on 2026-10-05: the .svg link is a broken image while the PNG twin renders. The fallback order is now PNG → inline SVG data URI (32 KB budget) → relative path with a loud warning.
• A failed sharp load is cached per attempt instead of forever, and the diagnostic moved out of the plugin directory: under the shell sandbox an install below ~/.dsh cannot be written, so the old one-time raster-diagnostic.txt write failed silently and the degradation stayed invisible for two days.
• The nudge's per-session counters are keyed by session and dropped on agent/disposed. The session/event observer cannot iterate a WeakMap, and reading the agent map threw usage.values is not a function — caught by scripts/_repro-nudge-channels.mjs.
• Neither channel could read the answer, so both were silently dead. Two separate causes, both found by probing the live event path rather than reading the code: (1) the usage ledger is created lazily at the first agent/pre-step, so a session's FIRST assistant message arrived before the ledger existed and was dropped; (2) the ledger clears its own text copy at every turn boundary, so a tools/post-execute read always saw an empty string. The reply text now lives in a session-keyed latestText map that only agent/disposed clears. A frame that was measured as "12 draws, 0 nudges" is what this looked like from outside.
• The session key accepts session.id, session.header.id, agent.sessionId and agent.id. Reading only session.id works on the real Session (a getter over its header) but degraded every equivalent object to 'unknown', which is what the repro exposed.
• decideNudge reads the reply text from usage, never from opts: text passed in the wrong argument silently degraded every call to the counter fallback. The readable-text path also had no reminder exit at all — only the steer — so a session that stopped drawing went silent instead of reminding.

v0.0.3

Added

• Published to npm: npm i dsh-inline-figures, or dsh plugin --profile <profile> add dsh-inline-figures.

Changed

• The Chinese README is README-zh.md (was README.zh.md). npm picks the README for a package page by globbing {README,README.*} in the package root and taking the first match, in directory order — with two matches the Chinese file won, so the package page showed Chinese for an English-default project. A hyphen keeps it out of that glob, which makes the English README the only candidate.
• README install order is npm first again, now that the package is on npm.
• The allow-version example no longer pins a stale version; it takes <version>.

v0.0.2

Added

• A "How it works" diagram in the README, one render per language, generated from a single layout by scripts/make-readme-diagram.mjs.

Changed

• README head is a machine-readable name / description table, so a reader — human or model — can tell what the plugin is before reading any prose.
• README install order: the repository spec comes first, because the package is not on npm yet.
• README "What it writes to disk" spells out the persistence: the session workspace only, no network calls, no uploads, no telemetry, 200 figures per session, and a figure is a reference rather than a copy.
• README dropped its Releasing and Known issues sections. Release steps now live in docs/MAINTAINER-NOTES.md, together with the open defects.
• Line endings are LF everywhere, matching the .gitattributes the repository declares.

Fixed

• Figures are readable in a dark GUI. A rasterizer has no prefers-color-scheme, so the PNG kept the stylesheet's light values on a transparent canvas and left titles, axis labels and timeline labels dark-on-dark. The PNG now gets an opaque canvas; the archived .svg stays transparent and theme-adaptive.
• Concurrent draws no longer collide. Three or more same-slug draw_figure calls in one step could fail to allocate a file name. A retry now re-reads the directory instead of incrementing a number that was read before the first write.
• The CHANGELOG carried two ## [Unreleased] headings, which made scripts/release.mjs read an empty section and refuse to release.

v0.0.1

First public release.

Added

• draw_figure host tool: a JSON figure spec (or a hand-authored SVG) goes in, a full-width figure file plus one inline Markdown line comes out.
• Five spec kinds: raw_svg (primary path, for free-form structures), architecture, compare, timeline, chart.
• Deterministic layout engine in lib/figures/ — 680-unit logical canvas, 1600-wide intrinsic size, golden-snapshot tested, never draws outside the canvas.
• SVG sanitizer for model-authored figures: rejects scripts, doctypes, entities, iframes, embeds and objects; strips event attributes, external references, <image>, <foreignObject> and comments.
• Portable ./engine entry with zero DSH or cordis dependencies, so the same renderer works in any Node or browser app.
• System-prompt guidance section: when to draw, how to place the figure, and the ASD-STE100-style prose and label rules.
• Soft nudge: one self-contained reminder when a session draws far below the guidance rate.
• PNG raster twin for every figure, because the GUI serves files with a CSP sandbox header and Chromium refuses to rasterize an SVG served that way. sharp is a normal dependency and ships prebuilt binaries, so the install needs no build step.
• Figure hygiene: per-session .gitignore, monotonic file numbering, and a 200-file LRU prune that removes a PNG twin with its SVG.
• Unit tests for the schema, the four presets, the sanitizer, the host file helpers, the nudge policy, the guidance text, the release gates and the official host-plugin contract, run with node --test.

Changed

• Packaged for the official install path. The harness supplies the @deepseek-ai/* runtime packages, so they are peer dependencies, not dependencies: nothing duplicates the runtime inside the profile, and the plugin manager refuses an incompatible runtime before it installs anything. dsh plugin add and the Web Plugins page are the supported ways in; the hand-rolled offline installer is kept only as a fallback for machines that cannot reach a registry.
• Renamed from @local/dsh-inline-figures to dsh-inline-figures; the bundle patch row now names the package, and the two are checked against each other.
• Every contributed resource registers through ctx.effect, so disabling the plugin row removes both the tool and the prompt section.
• Added the display metadata the plugin manager reads without activating the plugin: locale/en.json, locale/zh.json, and an exported icon.svg.
• README in two languages: README.md (English, default) and README.zh.md, each with a switcher at the top and its own rendered hero image (docs/assets/before-after.png, docs/assets/before-after.zh.png). Both come from one script, so they cannot drift apart. scripts/release.mjs keeps the version badge of every variant in step, and the test suite fails if one drifts or if a variant points at the other language's picture.
