 ## Unreleased
 
+- fix(doctor, preflight, platform-link): **a clean `fix property-sets --dry-run` on Mendix below 10.24.24 is no longer reported as "every unit has the property names Studio Pro writes".** mxcli's property table starts at 10.24.24, so on 10.24.18 (mxcli v0.27.0) the dry-run printed "Every unit already has the property names Studio Pro writes" while Mendix's `mx diff` exited 129 on a unit mxcli had written (mendixlabs/mxcli#1595). `doctor.sh --property-sets`, `--if-stale` and `--quick` now WARN "NOT PROOF" and name `mx diff <base>.mpr <mine>.mpr out.json` (exit 0) as the proof; the receipt records `unproven`; exit stays 0. `learned-detection-gaps.md` and `platform-link.md` said v0.26.0 closed the gap. Fixture P2b (11 cases). Baseline-routed, +18 words. — saingge
 - new(model-scope): **a write's whitespace-only units can now be found and put back.** mxcli v0.27.0's `alter entity … rename attribute` rewrote 135 units in 20 modules of a Mendix 10.24.18 app that never referenced the attribute; the only change in each was the line breaks between bracketed XPath conditions, and `mxcli diff-local` showed nothing (mendixlabs/mxcli#1596). New `project-bin/model-scope.py`: `report` sorts each changed unit into real or noise (every differing field is an XPath constraint that is equal once whitespace outside string literals is removed) and prints the real changes per module; `restore` checks the noise units out of `HEAD` and updates their ContentsHash rows through `mxpatch.py`; `check --staged` exits 1 when noise is staged (`MODEL_SCOPE_OK=1` lets one commit through). Not wired into `exec.sh` or the pre-commit hook yet. Fixture `tests/wave2/test-model-scope.sh`, with a golden before/after capture of a real v0.27.0 rename on a public model (`fixtures/model-scope/golden-v0.27.0/`) — saingge
 - fix(graph-sweep, lint): **the orphan list now says a flow used only by a pluggable widget's datasource or action property may have no catalog edge, and prints the one `mxcli search` that finds the page (it needs a `REFRESH CATALOG FULL SOURCE` catalog; this sweep reads a FULL one, so the note says to rebuild).** The caveat named only layout snippet calls, so a live flow read as "strong evidence of deadness" (`graph-sweep.sh` comment, `review-report.js` orphan detail, and the `lint-that-actually-runs.md` QUAL004 row, which only said the catalog "likely misses" the ref). Observed on a Mendix 10.24 app with mxcli v0.27.0: 5 live flows used only as a Gallery's or a third-party widget's microflow datasource had 0 `refs` rows, `show references to` said "no references found", `describe page` printed each, and QUAL004 flagged each. A Gallery with a microflow datasource and no microflow `onClick` had its ref (15 of 15); with both, only the `onClick` ref (2 of 2); the two Data grid 2 microflow datasources had theirs. The QUAL004 row now states that and links [mendixlabs/mxcli#1513](https://github.com/mendixlabs/mxcli/issues/1513) (open; reported for Data grid 2 on v0.26.0); the ledger entry and the pending-issue draft now say they are filed. Pinned by `test-catalog-edge-guard.sh` case 1 (fails on 393d253). — saingge
 - fix(bug-lookup): **`bin/bug-lookup.sh` also searches the project's own `bug-logs/**.md` drafts, marked `(project draft: <file>:<line>)`, after the ledger's output.** It searched only the toolkit ledger, so a bug a session had already written down in the project was invisible to the lookup run before the next experiment on the same error; the ledger's output and ranking are unchanged (drafts are ranked in a separate pass), `--full` and `--index` stay ledger-only, and `MXTK_PROJECT_DIR=` turns drafts off. Field: a Mendix 10.24 app with mxcli v0.27.0, 43 files in `bug-logs/`; the query "cannot be spliced" listed 0 project drafts at 393d253 and lists 3 (3 distinct files) now, each pointing at a `## ` line; the project was not written. Pinned by group P of `tests/wave2/test-bug-lookup.sh` (3 of its checks fail on 393d253) on synthetic drafts; the run under /bin/bash 3.2.57 passes, other awks not run. — saingge
