"""ORCH-095 — HTML-safety of dynamic data fields in render_task_tracker.

The live card text is sent/edited with parse_mode=HTML. It is assembled from
two kinds of slots:

  * category M (intentional markup, NEVER escaped): the clickable issue number
    (plane_issue_link -> <a href>), the ⏳-waiting links (link_for), the done
    line (_done_link), and the already-escaped title (esc_title);
  * category D (data, escaped EXACTLY once at the render boundary): durations
    (_fmt_minutes / _capped_review_str), the status label, model, effort, and
    the token/cost metrics.

The bug (ORCH-093 incident): _fmt_minutes returns the literal "<1м" for a
sub-minute stage; interpolated raw into HTML text Telegram parsed "<1м" as an
opening tag -> 400 can't parse entities -> EDIT_FAILED -> the card froze. ADR-001
closes the whole class by escaping every D-slot at the boundary (helper N._esc)
while keeping the M-slots intact (so the number stays clickable, no double-escape).

These tests assert: sub-minute durations are safe (TC-01/02/03), all data fields
escape special chars without double-escaping (TC-04/05/06), markup survives
(TC-07/08), the edit payload is parse-safe and the anti-duplicate invariant
(ORCH-087) holds (TC-09/10), and the render path never raises (TC-11).

Network is isolated (no live overlay HTTP); the DB is a temp SQLite.
