	1	# Composer context references
	2
	3	> For maintainers. Using T3 Code? See [docs/user](../user/).
	4
	5	Inline context references let a user message point at a typed payload from an exact position in
	6	its prose: an image, a file, a terminal excerpt, a picked page element, a preview annotation, a
	7	review comment, a file mention, or a skill. This document covers the wire contract and the pure
	8	codecs. Editor, rendering, and clipboard behaviour land in later PRs and get their own sections
	9	here as they arrive.
	10
	11	## Two linked concepts
	12
	13	- A context record is the payload. It lives in `message.context.records`, keyed by a
	14	`contextId`. Records never contain bytes: image and file records bind to an existing
	15	`ChatAttachment` by id.
	16	- A context reference is one occurrence in the document. It is a Markdown link in
	17	`message.text` that carries only the kind and the `contextId`. Two references can point at one
	18	record. A reference's label is display text and never identity.
	19
	20	[`composerContext.ts`][contract] defines version 1 of the record union. Every record has
	21	`version`, `contextId`, `kind`, and `label`, plus kind-specific fields with bounded lengths. The
	22	union is open: a kind this build does not know decodes to `UnknownContextRecord` with its
	23	`payload` preserved, and known kinds are excluded from that member so a malformed image record
	24	fails its own schema rather than sliding through unchecked. `OrchestrationMessageContext` wraps
	25	the records with `ForwardCompatibleArray`, so one undecodable record is dropped instead of failing
	26	the whole message. The field is optional on `OrchestrationMessage`, both turn-start commands, and
	27	`ThreadMessageSentPayload`. The decider and projector carry it through untouched.
	28
	29	## Identity namespaces
	30
	31	- `ComposerContextId`: durable payload identity. Branded. Values match `[a-z0-9_-]+` and do not
	32	require a `ctx_` prefix.
	33	- `ComposerContextReferenceId` (`ref_…`): one document occurrence. Branded. Lives in editor state,
	34	not on the wire and is regenerated when canonical Markdown is reparsed.
	35	- `ChatAttachmentId`: the existing server-owned attachment resource. A record's `attachmentId` is
	36	a binding, not the chip's identity, so upload normalization can rename the resource without
	37	rewriting references.
	38
	39	Clients mint context and reference ids. Shared code does not, because the Effect lint plugin
	40	rejects direct `crypto.randomUUID()` there.
	41
	42	## Canonical reference syntax
	43
	44	[`composerContextReferences.ts`][shared] owns the grammar:
	45
	46	```text
	47	[label](t3-context://v1/<kind>/<contextId>)
	48	![label](t3-context://v1/image/<contextId>)
	49	```
	50
	51	The parser accepts exactly the `t3-context:` scheme, the `v1` host, one kind segment matching
	52	`[a-z][a-z0-9-]{0,39}`, and one id segment matching `[a-z0-9_-]{1,128}` case-insensitively. Query
	53	strings, fragments, credentials, and extra segments are rejected. Labels are sanitized to survive
	54	a Markdown link (no brackets or line breaks, at most 200 characters, never empty). Links that fail
	55	to parse are ordinary text. `collectComposerInlineTokens` already rejects URI schemes for file
	56	links, so a context link is never mistaken for a mention.
	57
	58	## Provider projection
	59
	60	`projectComposerContextForProvider({ text, records })` builds what the provider reads:
	61
	62	1. Every reference becomes an in-place marker: `[Image: shot.png; ref=ctx_1]`.
	63	2. A trailing `<t3_context version="1">` envelope holds one `<context kind id>` entry per unique
	64	referenced id, in first-reference order. Records that are never referenced are not emitted.
	65	A referenced id with no record becomes `<context … unavailable="true"/>`. Mention and skill
	66	records produce a marker but no entry. Unknown kinds emit their payload as JSON.
	67	3. Captured text is data: any `<` that would open or close `t3_context` or `context` is escaped,
	68	so a terminal line or PR comment cannot forge a record.
	69
	70	Attachment bytes travel on the existing attachment channel; the envelope only carries metadata.
	71	Text without references is returned unchanged.
	72
	73	## Legacy messages
	74
	75	Messages sent before this feature carry trailing `<terminal_context>`, `<element_context>`, and
	76	`<preview_annotation>` blocks, `<review_comment>` blocks, and U+FFFC terminal placeholders.
	77	[`composerContextLegacy.ts`][legacy] upgrades them in memory:
	78
	79	- Review blocks become references in place. Blocks that trailed the original text are appended
	80	last, matching the old send order.
	81	- Trailing blocks peel off the end in reverse send order (preview, element, terminal).
	82	- Placeholders bind to terminal entries in order; entries without a placeholder are appended.
	83	- Ids are deterministic (`legacy_<kind>_<n>`) so re-running the upgrade is idempotent.

	91
	92	## Editor model (web and desktop)
	93
	94	`ComposerContextReferenceNode` (`apps/web/src/components/ComposerContextReferenceNode.tsx`) is
	95	the one inline Lexical node for every context kind. It stores `kind`, `contextId`, `label`, and a
	96	per-occurrence `referenceId`, and its text content is the canonical link. The prompt string carries
	97	payload identity and position, so rebuilding the editor restores equivalent chips; it does not
	98	preserve the editor-local occurrence ids. Old drafts that used the U+FFFC ordinal placeholder
	99	migrate on hydration: placeholders bind to the terminal contexts in array order, then any context
	100	the prompt does not mention is prepended as a link.
	101
	102	Records stay in the draft store's typed arrays for now. The editor builds a `Map` keyed by
	103	`contextId` from them (`composerContextRecordsFromDraft`) and provides it through
	104	`ComposerContextRecordsContext`. `ComposerContextReferenceChip` looks the record up and renders
	105	the kind's chip; an unknown kind or a missing record renders the unresolved chip instead of
	106	vanishing. Removing a chip removes only that occurrence; the composer's change handler compares
	107	the referenced ids against the draft array and drops records no chip points at.
	108
	109	Version 1 deliberately keeps kind presentation explicit in each client instead of exposing a
	110	runtime handler registry. The contract and codecs are shared; web/desktop render rich chips and
	111	mobile renders the readable label. Add a registry only when a third-party or runtime-defined kind
	112	must provide behaviour that cannot ship with the client. Likewise, a durable occurrence id belongs
	113	in the canonical reference syntax only if a future feature needs to address one occurrence across
	114	serialization boundaries.
	115
	116	Terminal context now follows the same send path as every other context record: the persisted
	117	message keeps its canonical link and structured record, while the provider projection replaces
	118	the link with a readable marker and includes the excerpt once in the context envelope. The legacy
	119	trailing `<terminal_context>` form is parsed only when reading messages sent by older clients.
	120
	121	## Sending and reading messages
	122
	123	The composer sends `message.text` as canonical prose with reference links and
	124	`message.context.records` built from the draft (`buildMessageContext` in
	125	`apps/web/src/lib/composerContextRecords.ts`). Expired terminal excerpts are dropped from both.
	126	The server projects provider text at turn start (`ProviderCommandReactor`), so the persisted
	127	message stays readable and the provider receives markers plus one envelope.
	128
	129	Review comments and preview annotations enter the draft through store mutators. A mounted composer
	130	registers a context insertion handler so panel-originated references land at its current or
	131	last-known caret; when no composer is mounted, the store appends them. Terminal excerpts and
	132	attachments use the same caret-first behavior. Removing a chip in the editor removes the record;
	133	removing a preview screenshot thumbnail removes its annotation and chip.
	134
	135	The transcript resolves a message with `resolveUserMessageContext`: structured context is used as
	136	is, older messages are upgraded in memory. `ChatMarkdown` renders `t3-context://` links through
	137	`renderContextReference`, which the timeline maps to chips through the web context-presentation
	138	registry. The registry declares compact, details, and expanded capabilities for every known kind,
	139	rejects duplicate surface handlers, and provides the unresolved fallback. Terminal excerpts,
	140	elements, review comments, and preview annotations open structured details popovers; images and
	141	videos use the shared media modal. Mobile renders context links as their labels.
	142
	143	Pull-request summaries currently travel as review-comment records with optional typed
	144	`pullRequest` metadata. The metadata is a snapshot of the number, title, URL, branches, state, and
	145	draft flag at attachment time. Web and desktop render the compact `#number` label and derive its
	146	status tone from that snapshot. Hover shows the snapshot details; activation resolves the URL
	147	against the current environment and opens the pull request in the thread's right panel. Records
	148	written before the metadata was added retain their legacy details and neutral pull-request tone.
	149
	150	## Attachments
	151
	152	Image and file records use the draft attachment's local id as `contextId` and carry an
	153	`attachmentId` binding. The composer sends the upload's pending id (or the local id on the
	154	data-URL path, via the optional `id` on `UploadChatImageAttachment`); the server's `Normalizer`
	155	rewrites every image and file record to the persisted id it assigns, so the stored message binds
	156	records to real resources. Optimistic rows bind to local ids and are replaced by the server copy.
	157
	158	In the composer, attaching a file or image inserts a chip at the caret (appended when the editor
	159	cannot take input). Files exist only as chips: a file whose last chip is deleted is removed and
	160	its upload released, and drafts that predate references get a chip appended on hydration. Images
	161	keep the thumbnail shelf as their inventory; deleting a chip leaves the image, and removing a
	162	thumbnail that is still referenced asks for confirmation before removing both. Old drafts do not
	163	gain image chips.
	164
	165	In the transcript an image chip opens the gallery preview, a video chip opens the media preview,
	166	and another file chip opens or downloads the file. The gallery still shows every image; file rows
	167	remain only for files no chip references.
	168
	169	## Clipboard
	170
	171	Every copy path writes the canonical Markdown as `text/plain` and, when the selection holds
	172	chips, a structured fragment under `web application/x-t3-context-fragment+json`
	173	(`ComposerContextClipboardFragment`: version, source environment/thread/message, records; no
	174	bytes, no URLs). Composer copy and cut add it through a Lexical command listener; transcript
	175	selection copy adds it from an `onCopyCapture` on the user message body while chips re-emit their
	176	links through `data-markdown-copy`; the whole-message button writes both through `ClipboardItem`
	177	and falls back to plain text.
	178
	179	On paste the composer decodes the fragment before the plain text. Records the draft does not
	180	already hold are imported: terminal excerpts and review comments as they are, preview
	181	annotations rebuilt from their record, and images or files re-fetched through the source
	182	environment's asset URL and attached under a fresh local id, with the pasted link rewritten to
	183	that id. A pasted binary reads as an unresolved chip until its bytes arrive; a fragment from
	184	another environment leaves binaries unresolved. Rendered chips and sent messages are never
	185	mutated by a paste.
	186
	187	Pasting across threads, projects, or environments uses the same path: the client mints an asset
	188	URL from the source environment, downloads the bytes, and attaches them here. There is no
	189	server-side clone; if the source is unreachable or the attachment is gone, a toast says so and
	190	the chip stays unresolved.
	191
	192	## Ids, persistence, and the stash
	193
	194	Producers keep their own id grammars; `toComposerContextId` folds anything outside
	195	`[a-z0-9_-]` into a slug plus a hash, deterministically, at the reference and record boundary.
	196	A preview annotation's context id is derived from `annotation-<id>` so it stays distinct from its
	197	screenshot image, whose attachment id is the annotation id; the record links the two through
	198	`screenshotContextId`.
	199
	200	`projection_thread_messages.context_json` persists records, so a restart or projection reload
	201	keeps chips resolvable. Prompt stash entries carry `records` for terminal excerpts, review
	202	comments, and preview annotations; stashing moves them out of the draft and restoring imports
	203	them back through the same importer the paste path uses.
	204
	205	Context produced by other panels reaches the caret through `setContextInsertionHandler`: a
	206	mounted composer registers an inserter for its draft and the store falls back to appending.
