Third annotation on HN's ledger: hn-date YYYY-MM-DD, derived
from Algolia's created_at_i (HN submission time). Immutable --
set on first append, never updated.

https://valhovey.github.io/gaia-mary/ -- hn-rank 1 -- hn-points 1128 -- hn-date 2026-05-22

Algolia's per-hit JSON already includes created_at_i so this is
a free add -- one more field in the jq projection, one more
column in the rank|points|date|url pipe-format, one optional
suffix on the annotation string.

epoch_to_date helper tries GNU date -d @N first (Debian, where
Igor actually runs) then BSD date -r N (local dev portability).
Falls back to empty if neither works; the annotation just gets
omitted in that case rather than breaking the read.

What it buys today: metadata when eyeballing the ledger. "Is this
URL from yesterday or from 2024?" answerable at a glance.

What it leaves room for tomorrow: optional decay-by-age in the
picker. Current sort stays points DESC, rank ASC -- if we
later want to fold age into the score (recent bangers above
ancient bangers when peaks match), the data's already there.

Brain surgery commit (back-fill hn-date on existing entries via
Algolia URL lookup) goes separately into the brain repo.
