sitemap/ — SiteMap tab (S0–S4 live)

S4: Monolith mode — the whole repo as ONE megalith in the Sprawl idiom: black-glass slab, per-service facade panels, glowing apertures where the code opens to the world (HTTP endpoints, sockets, brokers, datastores, IdP, outbound clients — the manifest's io facet, ALL heuristic tier with cited sources), the file constellation dimly visible inside, neon grid horizon, slow drift (held still under prefers-reduced-motion), scanline overlay. Aperture hover → kind/detail/source; click → the service's full I/O surface panel. Overflow gets an explicit +N more slit — no silent caps. NOTE: yaml server:/port: detection is a LINEAR line scan in harvest.mjs, because a multiline regex backtracks catastrophically on large yaml. Never reintroduce one.

3D code-structure viewer for the :7878 admin panel: services/containers → file tree → symbols (functions/classes/models/pages) + external links. Six themes ship (Megalith is exterior:true); demo.html's theme table is the enumeration, not this sentence.

• demo.html — the tab page (/sitemap/demo.html?project=<slug>, iframe view #sitemap, project-picker-following). Loads the LIVE per-project manifest data/<slug>.sitemap.json. It falls back to the fixture only when the fixture's own project is the one asked for, or when no ?project= is given; any other project with no live manifest says so. With no ?project= nothing live is requested, and without a fixture the badge reads NO PROJECT. The badge names which (LIVE · <slug>, STATIC DEMO · fixture (<project>), NO DATA · <slug>); the tab title names the project the loaded manifest declares, never one written into the page. Keyboard: Tab reaches the canvas and every service label, Enter or Space opens a label's card, arrow keys pan, +/- zoom within the wheel's distance limits, Escape closes the card, and a service card lists its files and vulnerabilities as buttons, which are the keyboard route to the instanced meshes a pointer picks by ray. The find-a-service box frames the chosen service and opens its card. URL parameters, beside ?project=: ?view=<theme> opens one of the six themes (city, organic, glass, monolith, noir, megalith) for this visit without changing the stored choice, which is for links and screenshots, and an unknown value falls back to the stored theme; ?mode=light|dark pins the light or dark mode over the stored and system preference, any other value is ignored; ?embed (or being framed) hides the page's own title. themes as data presets over ONE scene graph, three layout engines (row-wrapped treemap / count-scaled radial / monolith), instanced files AND district bases (2 draw calls at 11k files), lifecycle-aware rendering (superseded/retired services dimmed + badged — never blank, never clean), hover tooltip, click → symbol panel, external-links panel (esc()'d, https?://-only hrefs, noopener), coverage/freshness footer.
• harvest.mjs — SHARED harvest engine (universal-ctags + container topology + link harvest + provenance {ast|heuristic|inventory|void} + visible truncation). One implementation feeds both generators so fixture and live data cannot drift.
• ../monitor/sitemap-data.mjs — S2 full-fleet generator: every project in projects.json → data/<slug>.sitemap.json (a fleet repo's service dirs + its buildout as infra). The lifecycle mechanism — exclude/lifecycle with effectiveFrom gating, resolved by lifecycleOf in ../monitor/sitemap-data.mjs — reads the private registry, which declares both; a service it marks superseded or retired is dimmed and badged. Regenerating updates the tab with NO server restart.
• build-fixture.mjs — S0 fixture wrapper over the same engine: node sitemap/build-fixture.mjs <service-dir> … harvests the named services of the registry project CW_SITEMAP_FLEET names, and exits 1 when that names no project path. Output: data/fixture.sitemap.json — GITIGNORED and never committed (build-fixture.mjs:8 says so; .gitignore covers /sitemap/data/*.sitemap.json). Nothing under data/ is tracked.
• vendor/ — three.js r147 UMD + OrbitControls (MIT, vendored from unpkg; no CDN at runtime).

Schema: ../schema/sitemap.schema.json v2 (schemaVersion const 2; + lifecycle/supersededBy). Two code comments still say v1 — demo.html:39 and ../monitor/sitemap-data.mjs:7 — and the schema is the authority. Panel wiring: ../admin/serve.mjs /sitemap/ static route + 19th DIMENSIONS row (Code structure / SiteMap, universal-ctags, state:'live'). Needs brew install universal-ctags; without it every file caps at inventory tier — honest, never silently empty. Open ideas: cc.json exporter for CodeCharta as a second viewer; per-node lazy symbol detail beyond the click panel.
