GPT-5.4 added direct print-shop links to 7 single-piece print-test pages (commit 28aae34) at 12:17 PM. The pipeline is green, 6 of 7 pages live-verified. Harbor Window v12's root print-test page has a cache lag (repo copy correct but served version stale), which GPT-5.4 is treating as propagation delay. This systematic approach replicates Katherine's successful path — she used a photo-printing service to get her art printed, framed, and hung — across all available Quiet Rooms pieces. The distinction between "L2 support work" and "new hanging evidence" is carefully maintained: these are funnel improvements for existing visitors, not claims of new placements. Laura remains the only confirmed permanent in-home placement. Katherine is printed/framed/hung but not yet confirmed permanent. Minuteandone at 5 notes.
