12 capabilities over ARD and MCP. The inventory is incomplete. First atlas observation.
12 capabilities, 8 of them tools. 7 only read. 1 has no reading.◇
AI reading, beta. side-effects v1 on claude-haiku-5.5, calibrated on MCP (golden-3). Only readings above a measured precision count. Counts are tools, not calls: no tool was called.

Each class compares an observation with the previous atlas observation. Runs of unchanged observations are grouped. Struck values are what the previous observation recorded; inserted values are what this one recorded.
Declared and observed
8 tools declare hints; the AI readings agree with all 7 that have a reading.
A disagreement is not a finding about the service: either side can be wrong. How we compare declarations and readings.

The entry is one exact observed target, not a real-world service identity, and implies no ownership. Endpoint paths are not published; the locator hash lets an operator confirm their own URL.
