Idea	Status	Tags	Summary	Katz
language_server_rust	in-progress		A Rust binary replaces the Langium language-server process. The extension launches `reqlan-lsp` over stdio. Open `.rq` buffers parse with [parser_rust]. The open sequence is ["open-file-sequencing.rq".open_file_algorithm]. Workspace names and rename targets come from the ideas index under [application_memory]. Inbound hints wait for the host snapshot of that index. The inbound inlay hover is markdown. It lists each referencer as a file link. An idea hover shows styled idea content when ["../syntax/features-syntax.rq".idea_content_tooltip] is on. A closed file has no retained syntax tree. Go-to-definition cost is ["../syntax/features-syntax-highlighting.rq".reference_goto_definition_speed]. When the engine is `rust`, the server also serves `rq:[…]` document links, go-to-definition, and missing-idea diagnostics in non- `.rq` comments. One resolution supplies the link, the definition target, and the underline. The host strips file document links; Ctrl + click uses definition ( ["../syntax/features-syntax-highlighting.rq".editor_reference_activation] ). The host serves those links when the engine is `node`. Host commands prefer LSP custom requests, napi extract, and the ideas index. Move / delete planners still use Langium until index-backed planners land. The setting `reqlan.languageServer.engine` selects the binary. The default is `rust`. `node` remains only when the setting says so, or when the binary is not on disk yet. A local extension build compiles this binary with the napi addon ( [extension_host_native_stage] ). The extension launches `bin/reqlan-lsp`, else that release build. It never launches a debug build, because a debug build is slow and the extension build does not refresh it. Code actions match ["../vsc-primitives.rq".code_actions]: ignore, create below, import fixes, search or wrap, idea move and delete, and barrel page. Attribute and name catalogs drive completion. Rename and find-references use open buffers plus the ideas index. Inlay hints honour `reqlan.referencesInlayHints.enabled` and the host inbound snapshot. An import link uses the parser token span ( [import_from] ). The path links to the file. An imported idea name and its alias each link to that declaration. A namespace reference links the alias and the idea as separate names. A missing leaf reports an unresolved idea on that name.

missing_reference_colour_sequence	done		Paint links and errors in two steps. The hot path paints same-file names and import targets ( [outbound_one_hop] ). The background pass paints qualified-reference idea lines ( [lazy_features_after_outbound] ). Related: [unresolved_reference_diagnostics], [reference_rendering], [file_reference_errors], [import_does_not_exist_error]. Hot path: - URL references: document link, no error. - Wildcard references: document link, no error underline for zero matches. - Import path missing: error underline, no document link. - Imported idea present: document link to that idea line. - Imported idea missing: error underline, no document link. - Same-file idea missing: error underline, no document link. - Qualified reference: document link to the file from the path token. Do not underline a missing idea yet. Background pass: - Qualified idea present: document link to that idea line. - Qualified idea missing: error underline, and remove the document link. - Drop a false missing-idea error only for the range that this pass confirms. Keep a different missing name on the same line.	0.153
open_file_algorithm	done		When the editor opens or changes a `.rq` buffer, `reqlan-lsp` runs this sequence. Do not wait for the ideas index. Do not wait for a workspace crawl. Detail: [open_file_sequence_diagram]. Related: [open_file_reference_sequencing], [language_server_rust], [ast_lifecycle], [outbound_one_hop], [open_file_hot_path], [token_colour_sequence], [missing_reference_colour_sequence], [lazy_features_after_outbound]. The hot path finishes before the first diagnostics publish. 1. Parse this buffer once ( [ast_lifecycle] ). 2. Colour tokens from that parse ( [token_colour_sequence] ). 3. Emit same-file links and same-file missing-idea errors from that parse. 4. Parse each imported file once, at depth 1, for idea names and lines ( [outbound_one_hop] ). Link an imported name that exists. Underline an imported name that does not ( [missing_reference_colour_sequence] ). 5. Return. A qualified reference may link to its file from the path token. Do not read that file on this path. After that publish, a background pass fills the rest ( [lazy_features_after_outbound] ). That pass must not delay steps 1 – 5. The server sends the hot publish before it starts that pass. It runs that pass only while no client message waits. A hover or a definition request goes first. A change reuses the import roots loaded at open. It does not read the config again. The node engine keeps [node_engine_open_path].	0.330
outbound_one_hop	done		The hot path parses imported files only. For each import in the open buffer, parse that file once, then stop. Read idea names, idea lines, and import aliases. Do not parse files that the import references. Do not read SQLite. Prefer the open buffer text when that import is already open and dirty. Cache each parse by path plus file stamp ( modified time and size ) ( [lsp_session] ). A current stamp is one `stat`. Read and parse the file only when the stamp changed. Cache the open buffer by URI plus text fingerprint ( [open_file_hot_path] ). [local_symbolic_analysis] stays file-local. This hop is outside that extract. An extensionless import path prefers `.rq`, then the path as written ( [implicit_file_extension] ). A qualified reference that is not an import waits for [lazy_features_after_outbound].
