Titles - for the mentions that DO survive are NOT fetched with an extra API call - (kept deliberately simple and bounded) — each related item's title is a - generic, honest placeholder ("Referenced item #"), and its ``url`` - always resolves to a real, openable page in this same repository. This - is a known, documented simplification, not a bug. -* ``acceptance_criteria`` looks for the issue's own "Acceptance Criteria" - Markdown heading (``#`` through ``######``, case-insensitive) and only - collects checklist items (``- [ ]``/``- [x]``) from inside that section, - up to the next heading of equal-or-shallower depth. This matters because - a real work-item body commonly has a SEPARATE "Definition of Done" - section that also uses checklist syntax — without scoping to the - matching heading, those unrelated items would be silently folded into - "acceptance criteria" and misrepresent the issue. When no such heading - exists at all (ad-hoc issues with no fixed template), this falls back to - scanning the whole body, so those issues still get a best-effort result - instead of an always-empty list. -* ``truncated``/``returned``/``remaining``/``next_cursor`` describe pagination - over the ``related`` list only. ``description`` has its own independent, - generous hard safety cap (so the response stays bounded even for a - pathological issue body) and is never silently cut without a visible - notice appended. -* The regexes that derive ``acceptance_criteria``/``related`` never scan more - than ``_MAX_SCAN_CHARS`` of the raw body, and always run on a copy with - ``http(s)://`` links stripped first — otherwise a `#42` inside a URL - fragment (e.g. a doc anchor) would be mis-detected as a cross-reference to - issue #42, and a pathologically large body would cost unbounded regex work - on every call regardless of the display cap on ``description``. +Policy runs before ``build_provider``.
