+- new(canvas): **`project-bin/mf-canvas-facts.py` prints how a microflow or nanoflow lies on the Studio Pro canvas: labels on top of each other, lines through objects, note lines leaving the side that faces away, flows that run right-to-left or curl, captions wider than their shape, and decision captions that ask the opposite of their true branch (SENSE).** It prints facts, one line each, and no verdicts; read-only (it reads units through `mxpatch.py`), exit 2 when a flow could not be read. `verify-module.sh` runs it per module as an info rung (1c, log `14-canvas-facts.log`; a missing script is a FAULT, not a skip). Fixture `tests/wave2/test-mf-canvas-facts.sh` runs on a model mxcli v0.27.0 wrote (units and `.mpr` captured); `test-verify-module-446.sh` gains V8 for the rung. Calibration is from Studio Pro 10.24 screenshots, not verified on Studio Pro 11. Field evidence, measured 2026-10-21 on one Mendix 10.24 app: 1,588 flows read in one pass; on the 36 flows an mxcli-built branch added or changed in one module, OVERLAP 19, LINE 27, NOTE-SIDE 17, LEFTWARD 3, TURN 4, SENSE 9 before repair — saingge
 - fix(progress-report, build-plan-status): **HARNESS rows are no longer counted as built rows, and a module's `verify-module.sh` row shows once, as that module's sign-off status on its phase card, instead of as a row.** A HARNESS step is a module's sign-off, not a build, so it is out of every "x of y built" count: the phase cards, the plan rollup and the Stage 5 card in `progress-report.html`, and the lede of `build-plan-status.sh --html` ("N build rows", plus a "Not counted: N HARNESS rows" note). The verify row's evidence is read exactly as #501 reads it (`harness_verify`'s rule, now `verify_evidence` + `module_status` in `progress-report.py`; nothing new measured, no extra script run, no mxcli or mxbuild call) and shown as one line per module: `Verified ✓ <date> (LOOK n/n)`, `Verify owed - LOOK + CONFIRM`, `Verify stale (N builds since)` (or `(a script was marked done- after it)`), `Verify not run`, `built? no verify summary`, `Verify not clean <date> (<why>)` for a summary with a FAULT, FINDING or SKIPPED row, or `Verify clean <date>, LOOK n/n - held: State says <State>` when State is blocked or pending a person (held is not signed off, as #501 never promoted it); a State cell that disagrees is flagged under it, the rollup says how many modules are verified, and the Stage 5 card, KPI and owed text add ", k of n modules signed off". The Phase state badge is read from the build rows only (a phase of HARNESS rows alone says "sign-off only" and its card "Sign-off phase: no build rows"). A module with no verify row shows no status. Other HARNESS rows (a coherence pass, a harness run) stay in the row list, marked "(not counted)". `build-plan.md`, `build-plan.json` and the text output are unchanged, so agents still see every HARNESS step. **Behaviour change to check in your project:** the progress report's built counts drop the HARNESS rows (a plan of 10 rows with 2 HARNESS reads "x of 8"), and the verify rows leave the row tables. Fixture: `test-progress-harness-verify.sh` (H1-H10, N1-N6, both layouts). — MendixMau (decision 2026-10-21)
 - fix(exec): **a script restated from a stale DESCRIBE now WARNs instead of silently reverting an earlier exec** (#261). A script drafted from a DESCRIBE taken before an earlier script of the batch ran put four old messages back, with check, mxbuild and lint green. New `project-bin/describe-baseline.sh stamp` writes `-- baseline: <Doc> sha256=<hash>` (plus `-- baseline-mxcli: <version>`) from a DESCRIBE at draft time; `exec.sh` runs `verify` only for a script that carries the header, so other scripts cost one grep and no mxcli call. It reports DRIFT with the first lines of the diff, STALEHEADER, and RESTAMP after an mxcli upgrade (DESCRIBE text may change, so that is not called drift). A re-run by the script's own last recorded write (the #269 ledger) and a fresh model are not drift. Nothing is refused and the exit codes do not change. Preflight STOP 21 gains one clause (`-- supersedes:`, `stamp`, exec.sh only warns) and its trigger names `create or modify` (+24 words). Not-found DESCRIBE and `--version` output are captured from mxcli v0.26.0. Lands after the #269 PR; with it, supersedes draft #311. **Behaviour change to check in your project:** `exec.sh` output can carry `WARN: stale draft: …` lines, and the BUILD-LOG detail cell `WARN stale baseline: <docs>`; `MXTK_RESTATE_GUARD=off` skips the check. — AlvinnYeo (#261)
 - fix(exec): **re-running an older `mdlsource/` script over a newer owner's live work now WARNs instead of passing silently** (#269). Three field apps had 99/579, 130/357 and 38/159 documents created by more than one script, and a replay of an older one reverted the newer with exit 0 and every gate green. New `project-bin/script-owners.sh` maps each microflow, nanoflow, page and snippet to the scripts that create or restate it, in run order (digit runs compared as numbers, so `2-core/` runs before `11-fixes/`; `done-` ignored), and reads `-- supersedes:` / `-- superseded-by:` headers. `exec.sh` records every kept write in a machine-local last-writer ledger (`.claude/loop/script-owners/`, self-gitignored, compacted per write); `restore-mpr.sh` marks it on a manual restore. A replay WARNs only when the newer owner's write is live: ledger first, else one DESCRIBE per document, at most 5 per exec (the rest print `CONFLICT (not checked)`). A new owner without a supersedes header gets one `NOTE:` line on its first run, kept out of BUILD-LOG. Nothing is refused and the exit codes do not change. With no co-owner, `exec.sh` runs one grep over `mdlsource/` and no mxcli call. `gate-check.sh` prints the co-owned count when it is above 0. Part of the rebuilt draft #311 (with the #261 PR). **Behaviour change to check in your project:** `exec.sh` output can carry `WARN: restatement: …` and `NOTE: new owner of …` lines; the BUILD-LOG detail cell can carry `WARN reverts: <docs>`. Set `MXTK_RESTATE_GUARD=off` to skip the check. — MendixMau (#269)
