  Live probes on 2026-09-01 plus the version strings the surfaces report about
  themselves. Written by API Evangelist; UNIL publishes no changelog, no
  deprecation policy and no versioning statement for any of these surfaces.
note: >-
  None of UNIL's callable surfaces carries a version in its path or in a header.
  Version is discoverable only by reading what the application says about itself
  in a response body, which means a consumer cannot pin one.

    OAI-PMH Identify reports earliestDatestamp 2025-05-19T06:21:03Z — the
    effective start of the IRIS repository's harvestable record.

  event: version-observed
  detail: >-
    The DSpace-CRIS root document reported irisVersion 1.3.8, irisRole "leader".
- date: '2026-09-01'
  surface: IRIS
  event: version-drift
  detail: >-
    Re-probe returned irisVersion 1.3.13 and irisRole "follower" — two patch
    releases and a role change since June, announced nowhere. dspaceVersion and
    crisVersion both report the literal string "/", so the underlying DSpace
    version is not disclosed at all. The saved contract has been re-based to
    1.3.13.

  surface: SERVAL
  event: retired
  detail: >-
    serval.unil.ch, UNIL's previous institutional repository, returns HTTP 410
    Gone at both the root and /oai/request. It has been superseded by IRIS at
    iris.unil.ch / api.unil.ch/iris. This is a correct retirement — a real 410,
    not a soft-404 — and the old apis.yml-era pointer to it is dead and must not
    be re-added.

  surface: SPICA
  event: version-observed
  detail: >-
    SPICA declares no version anywhere in its documentation or responses; the
    saved contract's 1.0.0 is API Evangelist's, not UNIL's.
