 # Reading package
 This package implements the Chinese `language-reader` workspace. Its independent
 contracts are LanguageReader, ReadingReader, ReadingDocument, ReadingFeature, ReadingJob,
 ReadingVocabulary, ReadingWord, and ReadingOwner. Baseline Studio, the workspace agent, and checked
 source activation remain available. Reading entities expose AgentDocumentation;
 read `guide` to find this resource and its extension points from an entity.
 ## Run the workspace
 From the Quixos repository:
 ```sh
 nix run .#camino-dev -- start --template language-reader --dir /home/timothy/qx-language-reader --agent
 ```
 The command prints a local browser launch link. Reusing the directory resumes
 the same workspace and its independent authoring workbench. A different
 directory creates a fresh workspace from the Chinese template.
 ## Entities
 LanguageReader owns documents, annotation features, vocabulary, and durable jobs.
 Documents preserve their exact original text and source attribution. Their
 Canonical sourceRevision is a content hash; variant revisions identify an immutable
 adaptation. All ranges use original UTF-16 offsets in that document.
 Creating a rewritten document retains the original document. Features contain
 presentation preferences and a processor key; schemas and implementations belong
 in code. Feature changes use expectedRevision to protect concurrent edits.
 Inference is admitted through a persisted narrow Agent. Each scope request owns
 a thread and request; managed graph edges retain those associations. Completion
 subscriptions validate structured output and record results without an open
 reader tab. Reading annotations default to Luna without reasoning and fast
 mode. Cache keys include source revision, semantic configuration, scope, instructions,
 output schema and actual context. Model routing/profile and scheduling preferences
 do not invalidate completed semantic results. Results persist indefinitely until
 explicit regeneration or deletion; attempt history is separate from the indexed
 canonical successful result. Declarative model processors retain
 results across unrelated runtime and presentation edits. Local processors and
 prompt closures conservatively include the package source fingerprint. `ReadingFeature.processorRevision` exposes the checked processor identity
 without copying its implementation into graph state. Old processor results are
 hidden and old in-flight completions become stale after source activation.
 Duplicate requests reuse the job, including a recorded
 failure; explicit retries are bounded. Old feature results cannot replace newer
 configuration. The document source is untrusted data, not developer instructions.
 ## Add an annotation
 Edit `src/processors.ts` or import a new implementation there. A processor
 declares its label, computation strategy, scope, and instructions. A local
 processor returns source ranges directly. Section processors produce at most
 180 ranges in one pass over a bounded section. Focus processors explain a word
 or sentence and use neighboring text as context. Chinese initial features are
 in `src/examples/chinese.ts`; French implementations are source examples in
 `src/examples/french.ts`. Choosing another language is a workspace template or
 source change, not an in-app preset switch.
 Generation and reveal are independent. A single section-wide tagging pass can
 prepare before reading. A feature requiring one model call per word must be
 focused, cached, and lazy. Heavy hover requests should wait for deliberate dwell;
 cached or local annotations reveal immediately. Never start a per-word background
 fan-out to satisfy a precomputation setting. Leaving hover discards interest in
 its result; the durable request may still finish and populate its cache.
 Reader settings use a large modal with a reader selector, General settings,
 annotator navigation, and breadcrumbs. A document attaches to a ReadingReader;
 settings apply to all its attached documents. Cloning copies settings and creates
 independent annotator objects. General settings include size, maximum width
 (0 is unbounded), CSS font family/fallback list, and background.
 Premades insert enabled copies of existing processors. New annotators start with
 a visual type, optional title and type-specific color/font suggestions, then a
 natural-language behavior request. There is no model/content chooser. The agent
 creates checked code, generates a title if needed, chooses preparation strategy,
 and supplies any implementation-specific configuration controls.
 One processor can present a cached item through several rendering hooks. Declare
 `Processor.renders`, for example:
 ```ts
 renders: [
  { style: "replace", reveal: "always" },
  { style: "tooltip", reveal: "hover", content: "source" },
 ]
 ```
 Each hook keeps the original source range and data source. A replacement's color
 already controls its ink. A source tooltip slices the original French text
 locally, with no extra inference. `annotation-display.ts` filters/decorates the
 cached facts before all hooks; `render-hooks.ts` projects their appearances.
 Separate annotator objects can also share facts through `cache.identity` and the
 same semantic scope/options, as pinyin and hover pinyin do. Generation stays with
 the processor; reveal belongs to each rendering hook.
 Premades currently create one feature from code-owned catalog metadata. QX object
 initialization can install several edges from supplied references, including their
 reciprocal relationships. It does not clone neighboring objects. To instantiate
 a processor/renderer bundle as separate graph objects, create all of them with
 distinct creation keys in one checked transaction and pass references between
 seeds. `addFrenchReader` and `addReader(copy)` are working examples. No second
 construction mechanism is needed for multi-edge initialization.
 Text content loads before annotation history. Preparation waits for that history
 to prevent cache misses while it is still loading. Planning and display-mode
 changes have checked JavaScript implementations and run against the local graph;
 server validation remains the same. Measurement and segmentation caches survive
 page and annotation changes. Package source changes do not invalidate declarative
 model results unless instructions, schema, semantic options or actual context
 change. Update the task version in `processor-identity.ts` when changing the model
 request wire shape or shared task construction; the text planner is fingerprinted
 automatically.
 Styles are overhead, highlight, underline, color, tooltip, sidebar, replace, bold,
 and italic. Hover must not reflow text: labels, replacement, bold, italic, font
 changes, sizes and spacing use permanent or click activation instead. This also
 applies to custom render hooks. Tooltip/sidebar use hover or click. The renderer
 preserves canonical source mapping for replacement spans:
 selection/copy returns source text. Fitting words and short labels move together;
 oversized spans may wrap. Processing contours cover intervening rows and paragraph
 gaps with straight connectors, without diagonal spikes. The embedded feature author makes actual checked
 source changes, activates a successful candidate, and registers the new feature
 through LanguageReader.addFeature. It has source and graph capabilities; normal
 annotation inference has neither. Their prompts and capability settings are
 captured by the existing Agent admission implementation.
 ## Check and activate
 Inside an authored workbench, use `qx-workspace check` in each changed resource
 and then `root/`. Activate its successful report with `qx-workspace activate`.
 Inspect the selected identity and new feature afterward. Preserve unrelated
 source and concurrent edits. Never report successful activation after merely
 writing files. Failed compilation or activation must preserve the working app.
 Renderer code and source-selection tests live in
 LanguageReaderPresentation/src/canvas and tests/canvas.test.ts. Follow its
 RENDERER_PROVENANCE.md when maintaining the recovered measured canvas approach.
 Output schema changes require updating validation and consumer code together.
 ## Sources and read aloud
 Import pasted text or UTF-8 text files, Chinese Wikipedia articles, or opening
 excerpts from the existing Gutenberg catalog. Wikipedia imports retain their
 source URL and CC BY-SA attribution; requests use TextExtracts, a descriptive
 User-Agent, bounded results, caching, and timeouts. Difficulty rewriting creates
 a new document, leaving the imported original intact.
 Read-aloud settings store an ElevenLabs key and voice once in private workspace
 state. The public graph returns configured status, never the key. Playback uses
 the streaming text-to-speech endpoint for a selected passage, limited to 1,200
 codepoints per request; it does not automatically narrate an entire book. The
 network implementation is covered with mocked API responses; live paid audio
 requires a configured key and voice.
 Primary API references: [MediaWiki TextExtracts](https://www.mediawiki.org/wiki/Extension:TextExtracts),
 [Wikimedia User-Agent policy](https://foundation.wikimedia.org/wiki/Policy:Wikimedia_Foundation_User-Agent_Policy),
 and [ElevenLabs streaming text-to-speech](https://elevenlabs.io/docs/api-reference/text-to-speech/stream).
 ## Verification
 `nix run .#language-reader-qualification` from the monorepo runs native graph
 integration and real Chromium interaction tests. Package checks also run
 processor/output validation, mocked network tests, canvas collision/Unicode
 selection tests, and hover scheduling tests. The browser suite checks actual
 CJK canvas metrics, pointer and keyboard copy, scrolling, bounded hover
 admission/cache reuse, the visual editor, imports, and the embedded feature
 conversation at desktop and narrow widths.
 ## Inline annotator configuration
 Configuration belongs to annotator code and appears on its page in Reader settings.
 `Processor.config` is a list of `ConfigField` controls, or a function returning that
 list. Supported controls: `color`, `number`, `select`, `toggle`, `text`, with a key,
 label, typed default, optional numeric bounds and select choices. The grammar
 processor generates one color control per part of speech; names does the same for
 entity types. Declare every option in code so the server can validate it.
 `ReadingFeature.options` persists the JSON object. `configureOptions` checks
 `expectedRevision`, validates options and increments `configRevision` atomically.
 The UI edits a draft and saves all processor options together; appearance/reveal
 controls save directly when the processor explicitly declares them. `addFeature` requires `options` (use `"{}"` for defaults) and optional `authoring` (use null for premades).
 Concurrent edits reject cleanly. Changing display settings preserves raw cached results; only semantic inputs invalidate computation.
 `Processor.prompt(config)` can include validated config in developer instructions.
 Local processors receive config as their third argument.
 The presentation `annotationDisplays` registry can return per-item `color`, `fontFamily`, or
 `fontSize`, applied after strict model output validation. Model output stays the
 four-field range/text/tag contract; rendering choices are owned by checked code.
 Common options `fontFamily` and `fontSize` configure labels. Their style remains
 `overhead`; `options.placement` chooses `"above"` (default) or `"below"`. A
 `Processor.renders` hook can set `placement` independently. Both positions use
 fixed source lanes, and display changes reuse semantic caches. Wide labels gain
 faint alignment guides; hovering a label emphasizes its source without invoking
 word-hover tooltips or processors. Different
 fonts and sizes in the same annotation source stay on one row; each physical line
 reserves its maximum ascent/descent and shares the resulting baseline.
 The presentation renders declared fields automatically. For richer controls, add
 a React component to `annotatorConfigViews[processor]` in
 `LanguageReaderPresentation/src/annotator-config.tsx`; it receives `fields`,
 `values`, `disabled`, and `change(key, value)`. This component edits the same draft
 and validated options. Built annotators have no universal output-type editor.
 `Processor.settings` explicitly opts into color, font, or timing controls;
 `description` explains the behavior and `preset` defines a premade output.
 The New annotator panel can reuse any installed processor type with its code-owned
 controls, or describe a new type to the author. `LanguageReader.archiveType` takes
 `{processor, archived}` and updates `archivedTypes`, hiding a type from the creation
 library without changing its instances, implementation or caches. Restore it to
 make it discoverable again. `ReadingFeature.remove` removes only an instance.
 Creation choices are authoring instructions, not a universal runtime schema.
 Set `addFeature.authoring` to the supplied `authoringJob` when registering a new
 annotator; this links its original request and followups to that annotator.
 `customize.feature` links a change request to an existing annotator.
 `ReadingFeature.setEnabled` runs locally and preserves configuration revision
 and cached annotations across toggles.
 Do not bypass persistence or create per-word inference from a config component.
 The French word-gloss and passage-translation processors declare `profile: "cerebras-light"`
 to use GPT OSS 120B with low reasoning. Processor-owned profiles override the
 workspace default and participate in cache identity. Cerebras must be connected.
 The default inference profile is `quick-fast`: GPT-6 Luna without reasoning and
 fast mode. `LanguageReader.inferenceProfile` is configurable through the graph and
 captured for each request. Model-backed cache identity includes the effective
 profile; local processors use `local`. Feature authoring remains on balanced.
 Pending jobs mark the exact text segment with animated contours. This is
 a rendering overlay, independent of layout, and respects reduced-motion settings.
 Hover word feedback uses cached segmentation/layout immediately; heavyweight hover
 work still waits for dwell and reuses durable results.
 ## Text processing and reading windows
 `src/text-processing.ts` is the reusable source-indexed planner for words,
 sentences, chunks and context. `ReadingDocument.plan` returns target ranges for
 `kind: "focus"` or `"nearby"`; it never starts inference. The UI reports visible
 and nearby source ranges, then uses the same admission/cache path for automatic
 preparation, clicks, dwell hover and retries. Pages are the default view; the
 Reading layout control also offers scrolling. Navigation persists mode and source
 position independently of pixel layout. Selection and cache ranges always refer
 to the original document, across pagination, font changes and reflow.
 Defaults: focus targets at most 400 graphemes; context includes up to two sentences
 before and after, capped at 1,600 graphemes. This also bounds unpunctuated paragraphs.
 Automatic preparation uses stable chunks of at most 800 graphemes, preferring
 sentence/word boundaries. Pages prepare the current page plus its neighbors;
 scrolling prepares roughly one viewport above and below. Only two background
 model jobs are admitted concurrently. Independent scopes from the same annotator
 may use both slots; duplicate scopes reuse their existing requests. Unsent queued
 scopes and admitted work both show processing outlines.
 Moving away replaces unsent plans; admitted results finish and remain cached.
 Local passes use the same chunks without model admission. Errors do not cause an
 automatic retry loop. Focused interactions are independent of preparation slots.
 Authors can override the defaults with `Processor.processing`, a partial policy
 or `(config) => policy`. Available fields: `chunkChars`, `focusChars`,
 `contextChars`, `beforeSentences`, `afterSentences`, `prefetchChunks`, and
 `context: "nearby" | "document"`. For long-range references, a processor might
 choose `{ context: "document", contextChars: 12000, chunkChars: 2000 }`.
 Sizes have a generous 80,000-grapheme ceiling and radii a 20-unit ceiling.
 These are author choices, not extra user settings. Large prompts/results still
 obey transport and output bounds; choose batch outputs responsibly. Generation
 rejects oversized targets so callers cannot accidentally bypass the planner.
 `passageTranslation` demonstrates lazy article translation, producing per-sentence
 sidebar notes in nearby chunks. Add it from Premade annotators. Adapt text creates
 a linked lazy text variant for either translation or difficulty changes.
 Hover feedback changes source ink immediately and never draws a word outline.
 ## Tooltip presentation
 Features can use `style: "tooltip"` with `reveal: "hover"` or `"click"`.
 Choose Tooltip in the annotation editor, then choose its reveal trigger. Existing
 processors and generated/local content work unchanged; this is a presentation
 choice. `always` is unsupported for tooltips. Hover inference retains dwell,
 nearby preparation and cache behavior. Ready hover content opens immediately.
 The source word remains highlighted by ink on hover, without changing layout.
 `LanguageReaderPresentation/src/canvas/Tooltip.tsx` renders selectable React
 content in a native manual popover (the browser top layer). It escapes canvas,
 scroll-pane and component clipping while retaining component styles. Positioning
 uses source glyph rectangles in viewport coordinates, flips above/below and clamps
 to the viewport. Cards combine matching annotations and identify their sources.
 Hover cards allow a brief pointer crossing to select/copy their text. This grace
 period does not extend model hover intent. Click cards remain until dismissed or
 the anchor leaves view. Escape, outside clicks and the close button dismiss them;
 pagination, scroll and resize update or clear the anchor. No model work is owned
 by the tooltip component and no HTML from model output is interpreted.
 ## Lazy text variants
 ReadingDocument.rewrite creates a variant linked by canonical; it does not start
 inference. adaptation stores immutable canonical ranges and completed outputs.
 prepareVariant admits only the next section, bounded to 1400 graphemes, with
 nearby context. Requests deduplicate and explicit retries are bounded to three.
 Validated completions append in canonical order. Output length changes do not
 change canonical section identities or invalidate ready prefix annotations.
 The reader prepares ahead near the current page; ordinary annotators then work
 on generated text. This path serves both difficulty adaptation and translation.
 A failed section retains all completed text and offers an explicit retry. Closing
 the UI does not discard an admitted request. Variants are separate documents and
 inherit the source's reader, which can subsequently be changed.
 ## Embedded authoring
 customize captures reader, requested configuration, and prose intent separately.
 Jobs retain the reader link and a read-only configuration snapshot. Their threads
 are collapsed beneath that reader's settings; opening one shows a React request
 card rather than raw orchestration text, then ordinary follow-ups and questions.
 ConversationTranscript separates rendering from its graph controller, and the
 standard agent ThreadView also accepts renderItem for embedded request views.
 Before follow-ups, the author must re-read current reader settings and feature
 options; a request card records history and is not authoritative live state.
 ## Product language
 Use concrete labels and direct copy. Avoid slogans, inspirational filler,
 decorative all-caps branding, and boilerplate AI disclaimers. Explain empty states
 with a useful next action. Caveats should identify a specific limitation briefly.
 These directions also live in the default Workspace Agent prompt and harness.
 ## Semantic annotation caching
 Raw model/local facts are cached separately from display preferences. The pure
 cache.ts wrapper serializes processor identity, scope, generation and explicitly
 selected semantic options. Source revision/range and model profile complete the
 cache identity. Processor.cache.inputs opts into semantic fields; the default
 selects non-color config fields unless computation:false. prompt(config) sees
 only these semantic values. Changes to color, fonts, enabled state or display
 filters must never admit another model request. Install custom filtering/styling
 in LanguageReaderPresentation/src/annotation-display.ts, not model output.
 Pinyin batches every word in stable 160-grapheme nearby chunks, with tone marks
 and an estimated HSK level per token. The HSK slider filters cached facts locally.
 Hover pronunciation uses the same computation identity, including sentence context,
 so it does not request inference per word or duplicate the overhead pass. Two
 background slots bound preparation; visible chunks precede neighboring chunks.
 Context-sensitive annotation caches stay scoped to the canonical source/range;
 only introduce bare-word reuse for a processor whose context-independence is
 explicit. For ambiguous pronunciations/definitions retain context.
 ## Text library and generation
 The library lists texts; readers are reusable configurations attached to them.
 `ReadingDocument.archived` hides a text from the active collection without deleting
 its source, variants, annotations or threads. Restoring it changes only that flag.
 `LanguageReader.generateDocument` captures a reader and a bounded prose request,
 creates a durable `ReadingJob` of kind `text`, and uses the quick-fast inference
 agent. Only a validated `{title,text}` result creates and attaches the new text.
 The UI can close while the request runs; completion survives independently.
 `addFrenchReader` creates an independent reader with two click-only overhead
 sources and a small French sample. `src/examples/french.ts` supplies per-word
 contextual glosses for the selected sentence and a separate translation lane for
 a few sentences. Focus planning bounds the source range and supplies neighboring
 context. Clicking another passage replaces both visible scopes immediately.
 Ready results remain cached; revisiting a passage reuses them. This scope-based
 exclusivity belongs to click/focus annotations; ordinary word/sidebar annotations
 continue to follow their source word. Hover tooltip dismissal clears only native
 selection owned by the tooltip, so it does not intercept later canvas copying.
 Model annotations echo `source` alongside `start`/`end`; it must equal the exact
 original UTF-16 slice, including whitespace and punctuation. `text` remains the
 rendered pronunciation, gloss or replacement. `validateAnnotations` collects all
 indexed errors and strips the echo after validation. The job calls the shared
 `AgentRequest.correct` operation for at most two same-thread corrections, staying
 pending until valid or exhausted. Invalid results never enter the display cache.
 Local processors still receive range/content checks without an echo. An author
 may document a code-owned `verifySource:false` exception; `annotationSchemaFor`
 then supplies the corresponding schema. This affects semantic cache identity.
 The feature author uses `balanced-fast` (Sol, medium reasoning, fast mode).
 Inference-based features must be tried on actual reader text or representative
 sample text. Start with `cerebras-light` when connected; try Luna fast, then Sol
 fast if the output needs a stronger model. Check returned ranges and content,
 not just request completion. These are authoring choices, not reader settings.
 ## Reader extensions and vocabulary
 Sidebar panels and word/selection context-menu actions are ordinary React reader
 extensions, separate from annotators. `src/extensions.tsx` in the presentation
 provides a shared `ReaderContext` and `ReaderAction`; `reader-extensions.tsx` is the
 installation point. Actions can inspect the exact original range or cached annotation
 tags. Context menus use the browser top layer and keyboard focus/dismissal. Drag
 selection does not generate click annotations. Panels can include arbitrary UI.
 `ReadingVocabulary` is a named graph list, shared through each reader’s optional
 `vocabulary` edge (otherwise the library default). Its standalone editor supports
 search, add/remove and rename. The SDK `ObjectPicker` presents checked paginated
 lists and explicit selection, creation, preview and open-in-new-tab. Existing words
 remain in their original storage; `ensureVocabulary` attaches unlisted entries to
 the first default list through public contracts. Cloning a reader shares its list.
 Settings show the current text alongside configuration. This preview projects
 cached facts through current appearance/display options, never initiates inference.
 Author new data models simply, and refactor to richer domain entities when needed
 while preserving user values via supported transformations. Independently scoped UI
 work can use bounded Codex subagents; join/check before activation.

  markdown: `This is a language-learning workspace with Chinese example readers.
 LanguageReader owns documents, reader configurations, features, named vocabulary lists
 and durable jobs. Sidebar panels and React context-menu actions are reader extensions,
 independent of annotation processors. Read LanguageReaderPresentation/src/extensions.tsx,
 reader-extensions.tsx and vocabulary.tsx. ReaderContext carries document/source identity,
 word or selection range and computed annotations. Actions can apply to arbitrary
 selections or inspect annotation ranges/tags. Dragging a selection never invokes
 click annotators; context-menu actions operate on original source text. Settings
 include a live cached-text preview that never initiates inference. Vocabulary lists
 are shared graph entities with a standalone React editor. Choose them with the SDK
 ObjectPicker; locations and results are checked paginated queries, never file paths.
 Start new concepts simply and refactor when user needs grow (e.g. vocabulary to a
 flashcard database); retain existing values through supported public transactions.
 ReadingReader is an independent shared configuration: data contains name, size,
 width (0 means unbounded), font fallback list, background and configRevision.
 Its features relation contains enabled/disabled custom annotator objects.
 The creation library reuses installed processor types with independent instance
 settings. LanguageReader.archiveType takes {processor,archived}; archivedTypes
 only controls discovery. Archiving never changes existing instances or caches.
 ReadingFeature.remove removes one instance and leaves its processor installed.
 ReadingDocument.reader chooses the reader; changing reader settings affects all
 attached documents. LanguageReader.addReader with copy clones settings AND
 independent feature objects. addFeature.reader selects the intended reader; null
 uses the library default. Read the current reader and feature config before
 EVERY authoring turn, including follow-ups. Never overwrite changes based on an
 old request snapshot. Generate a concise descriptive title if no title is supplied.
 Canonical documents retain exact source text. Variants link through canonical,
 store section state in adaptation, and append ready output to data.text with a
 stable variant sourceRevision. prepareVariant requests one bounded canonical
 section (1400 graphemes) and deduplicates it; complete/applyVariant validates and
 appends sequentially. The UI prepares a few pages ahead, then annotation planning
 works on the ready output. Never send an entire long document for rewriting.
 Ranges refer to UTF-16 offsets in the displayed document; replacement annotation
 ranges still refer to the original source span, and copying returns that source.
 ReadingFeature.data configures presentation and reveal; processor implementations
 live in LanguageReaderRuntime/src/processors.ts. Add actual checked code there,
 including its computation strategy, then add a feature through the public graph.
 Read README.md before editing. Chinese and French source examples are workspace
 authoring examples, not an in-application language selector.
 Choose preparation with judgment: cheap local or batch computations can prepare
 nearby text; expensive contextual per-word work waits for intent and is cached.
 Reveal and computation timing are independent. Never use hover for behavior that
 reflows text, including labels, replacement, bold, italic, fonts, sizes or spacing.
 Use permanent or click activation for these. Tooltip/sidebar use hover or click;
 ink/highlight/underline may also be permanent.
 The shared text planner bounds focus to 400 graphemes and context to two neighboring
 sentences per side (at most 1600 graphemes). Section processing uses stable nearby
 chunks (800 graphemes, 180 results). ReadingDocument.plan computes source ranges
 without inference. Pages are the default; scroll is configurable. Preparation
 follows the current page plus neighbors, or a comparable scroll window, with
 two background model slots. Independent scopes from the same annotator may use both
 slots; duplicate scopes share existing requests. Unsent queued scopes and active work
 both show processing outlines. Processor.processing
 (partial policy or config function) can override chunkChars, focusChars, contextChars,
 beforeSentences, afterSentences, prefetchChunks and nearby/document context. Authors
 may widen context for long-range work. Read README.md for limits and extension examples.
 Passage translation is a lazy section annotator; do not translate entire articles
 through one giant click request. Local/section results may prepare early and reveal instantly.
 Expensive word/sentence processors remain focused and cached. Heavy hover waits
 for intentional dwell; leaving cancels interest, not an already admitted durable
 job. Never fire one background LLM call per word. Reveal timing does not choose
 computation cost. Readers may share named ReadingVocabulary objects. ReadingWord entries keep source terms; pinyin vocabularyMode is a display-only saved-word filter.
 Tooltip presentation uses style="tooltip" with hover or click reveal (not always).
 It is selectable React content in the browser popover top layer, anchored to
 source glyphs, outside canvas clipping. It reuses the existing processor and
 heavy-hover intent/cache path; never make extra calls from its UI.
 Renderer styles also include replace, bold and italic. Overhead-hover recolors the
 corresponding source span without activating word-hover tooltips or computation.
 Style overhead supports options.placement:"above" (default) or "below"; a
 Processor.renders hook can also declare placement. Each side keeps fixed source
 lanes. Position is display-only and must reuse cached semantic values. Long
 labels receive faint alignment guides, and punctuation retains its normal ink.
 Short words and fitting overhead labels keep their
 source together across line/page breaks; oversized runs may still split.
 Rendering source is LanguageReaderPresentation/src/canvas. It uses measured
 source spans, fixed rows per annotation source and exact source selection.
 Each annotator owns its inline configuration: Processor.config can declare fields
 or generate them; config.ts validates options on write. ReadingFeature.options
 stores a JSON object and configureOptions requires the current configRevision.
 Raw results persist indefinitely by source revision, target range, processor, scope,
 actual context and semantic options. Model profile, scheduling, color, font and
 display thresholds never invalidate semantic facts. An explicit retry regenerates. Processor.cache.inputs
 explicitly names semantic option keys; otherwise non-color, non-display config fields
 participate. Mark display-only fields computation:false. prompt(config) receives only
 semantic inputs. Appearance, typography and visibility filters must run in the
 presentation's annotation-display.ts; install an annotationDisplays function for
 custom filtering or multi-color styles. Do not persist decoration in model results.
 Underlines use the common display-only underlinePattern option: solid (default),
 dashed or squiggly. Changing the pattern must reuse the existing computation cache.
 The presentation's annotationDisplays hook can override underlinePattern per item
 alongside color and font; only these three patterns are valid. All patterns occupy
 the same underline band, so switching appearance must not move source text.
 Processor.renders projects one cached item through several style/reveal hooks;
 content:"source" makes a tooltip show the original source without inference.
 Replacement ink already follows its color. Share one computation rather than
 creating a request for each appearance. Separate feature objects can share results
 through cache.identity with matching scope/options. Multi-object presets belong
 in one transaction; initialization installs declared edges but never recursively
 clones neighbors. Declarative model results survive unrelated package edits.
 When changing model task construction, update the task identity version; local
 functions and prompt closures retain conservative source fingerprints. Declare
 cache.version for imported helpers when their semantic version can be maintained
 explicitly; bump it whenever those helpers change computation behavior.
 Prefer computing reusable facts once (e.g. pinyin + HSK level for every word),
 then changing a display filter locally. Context-dependent results are scoped to
 stable source chunks and their context: never reuse a bare-word cache for polyphonic
 pronunciation or contextual definitions without an explicit context policy.
 Pinyin and hover pinyin share one contextual section cache and two-slot preparation
 queue; all nearby word tokens prepare, irrespective of the displayed HSK threshold.
 The presentation's annotator-config.tsx renders declared controls and exposes
 annotatorConfigViews for purpose-built React components with the same values/change
 contract. Keep these controls inside the general annotator config, not separate
 workspace-global settings. Overhead font family/size are common options; mixed
 sizes share a source row baseline using maximum ascent/descent for each line.
 Library.inferenceProfile defaults to quick-fast (Luna, no reasoning, fast mode),
 is chosen in code by the author (no model picker), and routes future uncached requests.
 The feature-authoring agent uses balanced-fast (GPT-6.1 Sol, medium reasoning, fast mode).
 Test inference-based processors on a bounded excerpt from a text attached to this reader,
 or representative sample text when none is available. Try cerebras-light first when
 connected; assess output quality and fall back to quick-fast/light-fast or balanced-fast
 as needed. Always select fast mode where supported. Model annotation output includes
 source: the exact original text for start/end. The default validator rejects all
 source/range mismatches and reports every indexed error. AgentRequest.correct sends
 feedback in the same thread, retains task data/profile/schema, and allows two corrections
 before the job fails; invalid values never reach the display cache. Code can explicitly
 set Processor.verifySource:false for a documented exception. Local processors are
 range/content validated without a model source echo. Queued and active annotation work carry exact
 source ranges for a non-displacing processing outline; word hover immediately recolors source ink. Keep canvas
 layout and selection tests passing. Output schemas are code contracts, not user
 preferences. Code changes must pass qx-workspace check in affected resources
 and root; automatically activate the checked candidate with qx-workspace
 activate. A failed candidate leaves the working app intact.`,
