A shared vocabulary that every format writes in its own dialect - #18

Conversation
A game says a sound, a picture or a pane once, and each format writes it its own way or stands something in for it: MXP <SOUND>, Pueblo <img xch_sound>, HTML <audio>, a terminal nothing; a picture falls back to its description or address; a pane keeps its text in the main window. The types are core's (SoundMarkup, ImageMarkup, PaneMarkup, ...) with MarkupText factories and built-in codecs. The format packages supply the emitters: WithHtml for a browser, WithAnsi for a terminal's clear and BBCode's [img], and two new packages, MarkupString.Mxp (held to the client's <SUPPORT> answer) and MarkupString.Pueblo (names and attributes from the Pueblo client's source). Points (IPointMarkup) ride on a carrier that is not text: ToPlainText, ToString and equality leave it out, and a format with no emitter for a point writes nothing, not even the styling around it. The Ansi set emitters now keep foreign layers nested inside the styling inside it, so a picture inside a command link stays a link. The changelog's 2.2.0 entries move under their own heading.

In `@docs/releasing.md`:
- Around line 81-83: Update the coordinated-release and AOT/versioning
documentation to consistently describe all five packable packages instead of
three. In the package-validation instructions, state that each package gains its
baseline when its first release lands, then later builds are compared against
that published baseline; update the release checklist accordingly, including the
relevant README sections.
In `@MarkupString.Ansi/Emitters/AnsiEmitterSupport.cs`:
- Line 62: Update the WriteInner/Fold/WriteWrapped flow around FirstClaimed so
claimed ANSI layers are rendered in separate segments at each foreign-layer
boundary. For sequences such as [Bold, Tag, Red], do not fold Bold and Red
together; preserve Tag between the claimed layers in both ANSI and HTML output
while retaining existing behavior for contiguous claimed layers.
In `@MarkupString.Html/HtmlRegistration.cs`:
- Line 29: Make ElementHtmlEmitter policy-aware by adding an HtmlTagPolicy
dependency and applying it to every generated HtmlMarkup while preserving the
existing point and wrapping fallback behavior. Update the policy overload of
WithHtml to register ElementHtmlEmitter instances constructed with the supplied
policy, alongside the policy-bound HtmlTagEmitter, so SoundMarkup, ImageMarkup,
and PrefetchMarkup enforce it.
In `@MarkupString/MarkupTextRenderer.cs`:
- Around line 173-181: Enforce point-run validity at the MarkupText construction
and deserialization boundaries, including nested Wrap inputs and palette
entries: each point run must contain exactly one IPointMarkup with its valid
carrier, while non-point layers remain separate from that carrier. Update the
relevant MarkupText.Wrap, Normalise, and deserialization validation flow so
RenderRun cannot receive multiple points or invalid carriers, preserving
ordinary non-point runs.
In `@MarkupString/MarkupTextSerializer.cs`:
- Line 348: Update MarkupRegistry.With to reject any codec whose Kind is already
found by ElementCodecs, throwing an ArgumentException that identifies the
reserved kind and codec parameter. Keep ElementCodecs precedence in the lookup
within MarkupTextSerializer and do not reverse the resolution order.

…e HTML policy - A layer between two folded layers keeps its place: [bold, tag, red] is a bold inside a tag inside a red in HTML, Pueblo, MXP and BBCode, rather than one folded bold-red inside the tag. A terminal keeps the flat shape it had, where a style is state and the sequence is written once around the run. - WithHtml(policy) now holds the shared vocabulary's own elements to the policy too. A refused element leaves what a format that cannot express it leaves: nothing for a point, the text for the rest, so a refused picture keeps its description. - A point marks its carrier and nothing else. Wrap refuses a point over other text, which would have swallowed it, and Normalise drops a point that a cover puts out of place rather than losing the text under it. The renderer writes every point a run carries, once per carrier. - MarkupRegistry.With(IMarkupCodec) refuses the kinds core writes itself, which are read without consulting a registry. - The docs said three packages; there are five.

All five review findings are fixed in f2d6761, each answered in its thread, and the threads are resolved. Two needed a decision rather than the suggested patch:

The HTML fallback behavior matches the existing review guidance for refused shared-vocabulary elements. The terminal behavior keeps ANSI styling as state transitions rather than structural nesting. ✏️ Learnings added

AnsiStyle.Clear across delegated-layer boundaries, preventing outer styles such
as Red from wrapping delegated output after the clear barrier. Preserve clear

AnsiStyle.Clear discards the styling around it. With a layer from another package between two stretches of styling, the outer stretch was still written around the delegated output, so the colour came back. Found by CodeRabbit on #18. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Replaces #15 and #16. Those added per-dialect element APIs (
MxpElements.Sound,PuebloElements.Sound), so an author had to know the client before writing a sound. This PR adds one vocabulary instead: you say a thing once, and each format writes it in its own dialect or stands something else in for it.The vocabulary
The types live in core and describe the thing itself. Each format package decides how its format writes it:
WithMxp)WithPueblo)WithHtml)Sound,Music<SOUND>,<MUSIC><img xch_sound="play"|"loop" href><audio preload="none">StopSound<SOUND Off>/<MUSIC Off><img xch_sound="stop" xch_device>ms-sound-stopImage<IMAGE><img><img>[img]Pane<FRAME><DEST>…</DEST><xch_pane action="redirect">…and back to_previousms-paneClearScreen<xch_page clear="text">ms-clearESC[H ESC[2JPrefetch<xch_prefetch href xch_prob><link rel="prefetch">ExpireLinks<EXPIRE>ms-expireVariable,Gauge,Status<VAR>,<GAUGE>,<STAT>ms-*spansRelocate,LoginPrompt<RELOCATE>,<USER>/<PASSWORD>AnsiMarkupwith aLinkKind, so a picture inside a link is a clickable picture in every format.WithMxp(supports)takes the client's<SUPPORT>answer as a predicate overMxpRegistration.Elements. An element the client refused is written as a format without MXP writes it.Pueblo corrections, from the client source
The Pueblo client source (
uecasm/pueblo) shows three things #16 got wrong:xch_soundis a command (play/loop/stop), and the file goes inhref.xch_speechis Voxware voice chat, not text-to-speech, so it is gone.xch_prefetchreadshrefand ignores the tag without a nonzeroxch_prob.Panes redirect the stream to a named pane and back to
