   Decision recorded. The owner approved applying independently verified recommendations on 2026-10-12.

   • How is a truncated quote written? → The quote stays an exact contiguous substring and the truncation is recorded outside the fence; change SKILL.md
     Basis: plugins/knowledge/skills/docpage-digest/scripts/digest_fences.py:297-298; plugins/knowledge/skills/docpage-digest/SKILL.md:186-187

   SKILL.md says a truncated key-claim quote carries an ellipsis, but the fence gate requires each payload to be an exact contiguous substring of source.md, so the rule and the gate cannot both pass. Both are unchanged on main.

   Verification notes:

   • The same SKILL.md bullet also says 'joined source lines declare their join convention', which equally cannot pass an exact contiguous match; the doc change should cover joins too, not only ellipses.
   • Assumption about existing slices is unverifiable here (slices live outside this repo) but moot: an ellipsis fence already fails the gate.

   Verified by an independent fresh-context check (confirmed, risk low): gh issue view 7284 (open, no owner decision); origin/main plugins/knowledge/skills/docpage-digest/SKILL.md:186-187; origin/main scripts/digest_fences.py:285-305 (payload_in_source exact contiguous; only … is output truncation at :288); git grep check-fences-exact.py: gate parses CN. under Key claims; git log docpage-digest (latest #7268, #7214 unrelated); gh pr list docpage-digest: no fix

   Admission to an agent lane stays with the work-class rules and owner ratification.

   Owner batch-ratified this admission in an attended session on 2026-10-12: work-class: scoped. Rule: class C1-C3, no trust surface, the independent check confirmed the recorded decision, and no owner step remains.

   Agent Brief

   Type: Bug
   Summary: Make docpage-digest's truncated-quote rule agree with the exact-substring fence gate.

   Current behavior:
   The skill says a truncated key-claim quote carries an ellipsis and joined source lines declare their join convention, but the standing fence gate requires every fence payload to be an exact contiguous substring of the source. A quote written as the skill says fails the gate.

   Desired behavior:
   The skill says a key-claim fence payload is always an exact contiguous substring of the source. Truncation, and any join of source lines, is recorded outside the fence (for example in the line after it), never inside the payload. The gate is unchanged.

   Key interfaces:

   • The skill's 'Verbatim means verbatim' rule.
   • The fence gate's exact-match contract: unchanged.

   Acceptance criteria:

   • The skill no longer tells authors to put an ellipsis or a join marker inside a key-claim fence.
   • The skill says truncation and joins are recorded outside the fence.
   • The fence gate scripts are unchanged.
   • CI's skill-quality passes on the PR (a PR check; this run does not run it).
   • scripts/check-changelog-fragments.sh passes with a knowledge entry.

   Out of scope:

   • Rewriting existing slices.
   • Ellipsis segment matching in the gate.

   This was generated by AI during backlog shaping. Held, not admitted: this brief is drafted and checked, but the issue lane would stop on it today. It is admitted, by adding agent-ready, once the lane can run the skill-quality check scripts (Automation Lanes' PR #7912). Held under the owner's 2026-10-18 lane-narrowing course correction.
