docs(corrections): place principle parts 4c, 4e and 4f in /corrections:codify #12716

Refs #7589

Outcome

Parts 4c, 4e and 4f of principle-encode-lessons-in-structure each become a reasoned sentence in /corrections:codify, and the pstack record lists them as placed. This is #7589's remainder: its nine sub-issues are closed, and these three parts had no owning issue.

Done when

The done-when lines below are copied from #7589's Remainder section as written.

• Part 4c ("When you catch yourself writing the same instruction a second time") is a reasoned sentence in plugins/corrections/skills/codify/actions/note.md, Consent section: an agent that writes the same instruction or correction a second time appends a note, because a second occurrence shows a prose rule did not hold.
• Part 4e ("decide if it's a one-off or a pattern. Route it ... Close the loop: don't just record; apply now or create a concrete todo") is a reasoned sentence in plugins/corrections/skills/codify/SKILL.md, section 3 (Place the lesson by scope): a one-off stays a note row, a recurring mistake gets a check, a mistake that holds for every repository becomes a team standard, and recording a lesson is not the end: it ends in a proposed check, a placed rule or a filed work item, because a lesson that is only recorded is not acted on. Codify still proposes and never builds a rung.
• Part 4f ("Acknowledging without recording", "Recording without routing") is a reasoned sentence in plugins/corrections/skills/codify/actions/note.md, opening paragraph: a correction the agent only acknowledges is lost when the session ends, and a note that group never routes to /corrections:codify changes nothing.
• docs/upstream/cursor-pstack.md's principle-parts check lists 4c, 4e and 4f as placed, with their homes, and no longer names corrections: new plugin with /corrections:codify #7573 as their owner.

Notes

Drafted by the issue-triage session. Agent choice, not an owner answer. The quoted part text is from the cursor/plugins version decision 58 mapped (00b14f1df3), restated in #7589, so the work needs nothing outside this repository.
