CONTEXT: os-aidd-lint's Tier-2 eval harness (plugins/os-aidd-lint/eval/bin/run --tier haiku) was run on 2026-07-26 as part of the change-control obligation for a charter edit. Its generalization fixture judges plugins/os-sdlc/skills/mine-lints/SKILL.md at current HEAD. It returned three duplicated-authority findings against that file. These were reviewed by an independent external model (Codex, GPT-5.6 tier) and judged TRUE POSITIVES, not false positives and not a regression from the charter edit. Filing so they aren't lost.

FINDINGS — all in plugins/os-sdlc/skills/mine-lints/SKILL.md:

Line 32 — paraphrases references/reconcile-gate.md's "Already caught by an existing cop — excluded, no ticket". It is a paraphrase, not a pointer: it does not name the reference file.
Line 33 — near-repeats references/reconcile-gate.md's "never silently patch the cop" instruction, with added substance. Again a paraphrase, not a pointer.
Line 34 — reads "Do not file a ticket whose Correction diff doesn't actually clear its own Detection algorithm, or implement a cop straight from a raw finding instead of its ticket." This independently restates operative content owned by TWO other files: plugins/os-sdlc/reference/lint-rule-ticket-template.md's pre-filing consistency check, and references/implement-cop.md step 2.

IMPORTANT DISTINCTION to record in the issue: line 34 is NOT the same text as the charter's pinned counter-example. That counter-example is mine-lints step 4 at HEAD ("body following plugins/os-sdlc/reference/lint-rule-ticket-template.md exactly, including its pre-filing consistency check"), which remains correctly unflagged — it is a pointer. The charter's pointer-vs-paraphrase boundary held.

PRESCRIBED FIX (from the charter's own duplicated-authority entry): pick one owner per rule and replace the other occurrence with a pointer, never a paraphrase. Codex's suggested compliant wording for lines 32-33: "Follow references/reconcile-gate.md for already-caught findings and missed-cop handling."

NOTE: this is a change to an os-sdlc skill file, dogfooded by os-aidd-lint. It is the first cross-plugin true-positive the Tier-2 judge has produced against a file that is not its own.

**CONTEXT:** os-aidd-lint's Tier-2 eval harness (`plugins/os-aidd-lint/eval/bin/run --tier haiku`) was run on 2026-07-26 as part of the change-control obligation for a charter edit. Its generalization fixture judges `plugins/os-sdlc/skills/mine-lints/SKILL.md` at current HEAD. It returned three `duplicated-authority` findings against that file.
