Evaluated the Open Knowledge Format (GoogleCloudPlatform/knowledge-catalog okf
v0.2, scaccogatto/okf-skills) as a replacement for our decision-record system and
rejected it: its conformance rules are deliberately permissive exactly where ours
are strict (broken links, unknown types and missing fields must all be tolerated;
`deprecated` points at no successor), and its stable identity is the file path,
which the breadcrumb rule tells agents not to trust.
Adopted two of its optional families instead, additively:
- `stale-after: YYYY-MM-DD` on the metadata line — marks a record asserting an
outside-world fact as due for re-confirmation. Absolute date, no TTL.
- `**Sources:**` in the metadata block — the evidence a record rests on, as
distinct from `Signals:` (recall keywords).
Neither is required; absence is never an error. A malformed `stale-after` is
blocking (it would silently never fire), but a past-due record is only a
non-blocking `::notice::` — going stale is the passage of time, not a defect in
whatever commit is under test. The catalog's new "Review due" section renders the
date only and never a clock-derived verdict, so it cannot drift `--check` red on a
calendar boundary with no commit touching the corpus.
No backfill: no existing record adopts either field here.
fixes#603
_anchor() mapped each space/hyphen to its own '-' without collapsing runs,
so the standard heading separator " — " (space, em-dash, space) produced a
double hyphen in every generated anchor. Since nearly every real decision
record heading uses that separator, this made the catalog emit a dead link
for essentially every row. Fix: after building the char list, collapse
consecutive '-' into one and strip leading/trailing '-' via re.sub, matching
how Goldmark/GitHub/Gitea sluggers behave.
Also fixed main() writing an extra trailing newline (want already ends in
"\n", then "+ \n" appended a second one) so docs/decisions/README.md now
ends with exactly one trailing newline; --check still compares via .strip().
Added test_anchor_collapses_em_dash_and_keeps_underscore to pin the anchor
behavior against the reported iptv.base_url case.

Adds scripts/build_decisions_catalog.py, which renders docs/decisions/README.md
as a compact table of only 'active' decision records (sorted by key), and its
test scripts/tests/test_build_catalog.py. Supports --check for CI drift
detection. No decision records are migrated yet, so the generated catalog is
currently empty (banner + header only) — expected at this stage.
