Every app and artifact on the platform, its current version, and every older version still on disk. Each version links to the real deployed file so any one can be found and opened, no guessing at a stale local path.
Current versions follow the alias targets in vercel.json. Dates are file timestamps; some also appear in CHANGELOG.md.
Two conventions to know. The older demo snapshots (the Pollica demo lineage, the prior Reckoning and Tracker builds) are immutable: each meaningful change is cut as a new versioned file and the prior file is kept untouched, per the artifact-versioning rule in CLAUDE.md. Link to the stable alias (for example /halcyon), never to a _vN path. The new MVP apps under apps/<slug>/ are single-file: the version is an in-page label (the title and the .pill, for example "MVP v0.3"), with no _vN file history yet.
Group
Ecosystem map / Tessera
The mapping artifact. The Ecosystem Mapping Agent (the meadow-map demo) is the mature, versioned product; Tessera is its named app shell. The Pollica demo lineage below is this artifact's predecessor (v9.04 was copied from pollica_demo_v9.03).
The sensor-fleet tracker UI. Note: the hub's Triton tool tile still points at 8.3.7, while the canonical /triton alias is 8.3.9 (see the firmware/tracker pairing in CHANGELOG.md).
The immutable snapshots in halcyon/Pollica Demo/ that the Ecosystem Mapping Agent grew out of. These are not behind an alias: the live successor is /ecosystem-mapping-agent (v9.05). The "LOCAL" prefix marks file-protocol local snapshots. v8 is the stale build a stale link landed on; open the alias instead.
The constellation under apps/<slug>/. Each is single-file with an in-page version label (title + .pill), no _vN file history yet. The five share one project via ?project=pollica, no backend. They adopt versions at their next bump.
The platform pages: the project console, the Pollica narrative and deck, the supporting explainers, and the hub itself. The dashboard's version is the Project Manager version in platform/astraeus-pm.json.
