# Convenient-Invention Fact-Check - Chapter 15

id: convenient_invention | owner: codex | target: raw draft vs integrated revision

`DIFF SCOPE: output/drafts/claude/chapter_15.round_01.md vs output/chapters/chapter_15.md — 9 changed regions, 7 new or altered factual assertions extracted`

INVENTION CANDIDATE #1
post-edit text: `"It occupied one narrow strip of sill and too much of June's attention."`
pre-edit text at that point: `"It was developing a presence."`
class: detail
canon check: continuity Ch14 says June took the mineral spirits jar; chapter 15 raw already placed it on the windowsill. No contradiction.
verdict: CANON-COMPATIBLE — replaces personification with concrete placement/attention, not a new plot fact.

INVENTION CANDIDATE #2
post-edit text: `"The building's a printshop with a community arts program attached. Or the other way around, depending on which grant we're answering to."`
pre-edit text at that point: `"a printshop with a community arts program stapled to it... The job is both staples."`
class: detail
canon check: canon_sheet entry 36 licenses "Tasker Street Philadelphia printshop programs/fabrication role"; the edit preserves that institution.
verdict: CANON-COMPATIBLE.

INVENTION CANDIDATE #3
post-edit text: `"screen ventilation that only stays decent if someone changes the filters on schedule."`
pre-edit text at that point: `"The ventilation over the screen area passed inspection out of pity."`
class: detail
canon check: no canon_sheet entry names Tasker ventilation; raw draft already established screen-area ventilation as a condition issue.
verdict: CANON-COMPATIBLE — same local job-detail category, altered to be functional rather than comic; add to continuity if the Tasker facility details are later reused.

INVENTION CANDIDATE #4
post-edit text: `"Benefits after ninety days."`
pre-edit text at that point: `"Benefits after ninety days, which I know is a sentence you haven't heard in a while."`
class: detail
canon check: no contradiction with canon entry 36's W-2/paycheck terms; raw draft already contained the benefits timing.
verdict: CANON-COMPATIBLE.

INVENTION CANDIDATE #5
post-edit text: `"The numbers are in range."`
pre-edit text at that point: `"You can do math."`
class: detail/motivation
canon check: story_bible states the offer must be "generous and credible"; chapter packet requires Philadelphia be cheaper/steadier. The edit preserves the rent-pressure function without inventing an exact amount.
verdict: CANON-COMPATIBLE.

INVENTION CANDIDATE #6
post-edit text: `"The line that interested her was true up the Vandercook. Not the wall. The press."`
pre-edit text at that point: same insight plus a longer self-spectation/thesis explanation.
class: motivation
canon check: story_bible key risk and thread ledger S-OFFER-01 require the offer to repeat art-adjacent safety; the edit preserves the established motivation while removing excess explanation.
verdict: CANON-COMPATIBLE.

INVENTION CANDIDATE #7
post-edit text: `"because she needed a task with a beginning and an end."`
pre-edit text at that point: `"because the apartment had gotten small in a way that wanted handling."`
class: motivation
canon check: June voice card says under stress she "packs, sorts, cleans brushes she has not used"; replacing environment-as-agent with a task impulse matches canon.
verdict: CANON-COMPATIBLE.

Verdict: `NO-INVENTIONS`

Revision orders: none. Tracker note: if future chapters reuse Tasker facility maintenance, add "screen ventilation filter schedule" to continuity; it is local color here, not load-bearing canon.
