# Section 9 figure plan — qualitative experiment

## Status and candidate composition

**Status:** textual production plan only; `author-supply/provenance-gated`. No rendering or artifact promotion is authorized. **Candidate composition:** one compact apparatus schematic plus a selected subset of single-frame experimental/CFD pairs: one steady row and zero or more Illusion rows. Do not require every Illusion case. If provenance or legibility fails, omit a row; if all image gates fail, use schematic-only or no figure.

**Figure job:** document the physical setup and let the reader inspect named-condition morphology in separate experimental and CFD views. Juxtaposition means correspondence by author-bound condition only. It is not registration, overlay, experimental validation, CFD agreement or quantitative comparison. A single frame cannot establish shedding frequency or any temporal behavior.

## Layout

Use a two-column grid after a full-width or left-side apparatus panel:

- **(a) Apparatus schematic:** compact facility → carriage/pinball actuation → open-loop command → image-acquisition path.
- **(b–c) Selected steady row:** experimental single frame | corresponding named-condition CFD single frame.
- **(d–e), optional:** one selected Illusion row in the same order.
- **Additional Illusion rows:** include only if each adds a distinct morphology needed by Frank's argument and remains legible. Drop before compressing provenance or claim ceilings.

Keep experimental and CFD labels explicit. Do not share a colour bar, scale bar, coordinates or annotations in a way that implies common calibration. No difference image, overlay, registration marks, metric, frequency annotation, velocity vectors, vorticity equivalence or efficacy score.

## Panel contracts

### Panel (a) — apparatus schematic

- **Role:** establish physical configuration and open-loop execution/acquisition path.
- **Exact source:** `[AUTHOR SUPPLY: exact schematic path/hash; original editable source; version/date; permission]`. No matching file was located under the inspected `/home/frank14f` paths.
- **Author fields:** facility/test section and boundaries; towing direction; carriage/rail/rack; pinball geometry/body order; cylinder drive; command source and units; imaging/tracer path; any sensor shown; elements not synchronized or not used for feedback.
- **Processing:** `[redraw or direct use; dimensions preserved; labels added; changes from original]`.
- **Caption ceiling:** apparatus context and open-loop signal path only. Do not claim calibrated accuracy, closed-loop operation, synchronized force acquisition or experimental outcome.
- **Readiness:** `author-supply-gated`.
- **Fallback:** concise apparatus prose; omit schematic if it becomes a component diary or lacks source permission.

### Panels (b–c) — selected steady experimental/CFD views

- **Role:** show one author-selected named steady morphology comparison.
- **Experimental source:** `[AUTHOR SUPPLY: exact raw image path/hash]`; `[trial ID/date/setup]`; `[reference or controlled condition]`; `[frame index/time]`; `[camera/view/FOV/spatial scale or uncalibrated]`; `[dye injection]`; `[crop/enhancement]`; `[repeat and selection rule]`; `[permission]`.
- **CFD source:** `[AUTHOR SUPPLY or audit: exact image path/hash]`; `[CelerisLab/DynamisLab case identity and configuration]`; `[action/body order/sign]`; `[simulation step/frame]`; `[field-to-streakline processing and render settings]`. Candidate generation/history paths exist at `/home/frank14f/CelerisLab/tests/postproc/run_exp_ctrl_matrix_streakline.py`, `/home/frank14f/CelerisLab/tests/postproc/experiment.ipynb`, and `/home/frank14f/CelerisLab/tests/output/{exp_ctrl_matrix_streak_nx1500,stealth_steady_sweep_nx1500}/manifest.json`, but the manifest-referenced PNGs were not present and are not proven to be the author's counterpart.
- **Layout:** same row, experiment left and CFD right, independent labels/scales; use similar crop only if honestly disclosed, never geometric registration.
- **Caption ceiling:** `Single-frame dye visualization and separately generated CFD view for the named steady condition; qualitative morphology only.` Frank inserts the exact visible observation after provenance review. No field matching, straightness estimator, velocity/force inference, validation or agreement.
- **Readiness:** `author-supply-gated`; computational source additionally needs exact case/frame audit.
- **Fallback:** apparatus-only figure or omit this row. Never reconstruct from a manifest or notebook screenshot.

### Panels (d–e) — selected Illusion experimental/CFD views (optional)

- **Role:** show one selected named Illusion morphology; not all available cases.
- **Experimental source:** `[AUTHOR SUPPLY: raw path/hash, trial ID, exact Illusion condition, comparator role, frame index/time, camera/view/FOV/scale, dye protocol, processing, repeats/selection, permission]`.
- **CFD source:** `[AUTHOR SUPPLY or audit: exact path/hash, case/target identity, configuration, action/body mapping, step/frame and streakline/vorticity processing]`. Potential CFD analytic-action definitions and historical outputs exist in `/home/frank14f/CelerisLab/tests/specs/exp_ctrl_matrix.md`, `/home/frank14f/CelerisLab/tests/postproc/run_exp_ctrl_matrix_{vorticity,streakline}.py`, and the corresponding `tests/output/.../manifest.json` records; exact manuscript mapping remains unresolved.
- **Layout:** experiment left, CFD right; independent acquisition labels. If multiple Illusion rows are retained, each needs its own condition and observation; do not imply an ordered frequency series.
- **Caption ceiling:** `Single-frame dye visualization and separately generated CFD view for the named Illusion condition; qualitative morphology only.` **Mandatory:** `A single frame does not establish shedding frequency or any temporal change.` No frequency multiplier, phase, waveform recovery, agreement, validation or quantitative efficacy.
- **Readiness:** `author-supply-gated`.
- **Fallback:** omit the Illusion row(s); the section remains a short author interface.

## Author production manifest requirements

Before any panel survives, Frank must resolve and approve: experiment configuration and boundaries; trial ID to exact CFD case/frame mapping; flow direction, image orientation and any mirror/rotation; whether the action shown is commanded, converted apparatus input or measured body motion (never conflate them); action/body order/sign/units; exposure, illumination and frame rate, or explicit absence/nonavailability; raw-media path/hash through every crop/enhancement to the rendered output; comparator semantics; apparatus-schematic provenance/editable source; final author crop and caption approval; and publication/reuse rights. Also record trial selection/repeats and whether spatial scale is calibrated or absent. Missing any claim-critical field triggers the strict omission fallback.

## CFD streakline processing disclosure

If a CelerisLab streakline image is selected, disclose the exact release points/mode, injection count, sampled velocity-frame interval, integration (`bilinear space + linear time interpolation + RK4` in the current library), substep settings, diffusion coefficient, particle filtering, age decay, density binning, Gaussian blur, colour/background, simulation step and crop. These fields describe rendering; they do not make the CFD image a calibrated dye model.

If a vorticity image is selected instead, label it `CFD vorticity`, give the plotted range and frame/step, and do not visually equate it with dye intensity. Prefer a streakline-like CFD counterpart when Frank's purpose is morphology, but only from an existing audited artifact or separately authorized future production.

## Caption skeleton — Frank to complete

> **Figure X.** (a) [apparatus and open-loop command/acquisition path; source/version]. (b,c) [steady experimental trial/frame/condition] and a separately generated CFD view for [exact named condition/case/frame/rendering]. (d,e) [optional selected Illusion trial/frame/condition] and its separately generated CFD view. Experimental and CFD images are unregistered, acquisition-specific single-frame views shown only for qualitative morphology. [Exact processing/scale statements.] A single frame does not establish shedding frequency, velocity, force, field matching, quantitative agreement or CFD validation.

## Readiness gate and fallback order

A panel passes only with exact source, case/trial role, condition/action, frame/step, view/scale status, processing, selection/repeats and permission. The caption must preserve open-loop, separate-acquisition and morphology-only limits.

Fallback order:
1. drop extra Illusion rows;
2. drop the Illusion row entirely;
3. retain schematic + steady row only;
4. retain schematic only;
5. omit the figure and keep the author-owned textual boundary.

## Normalized readiness

Plan `author-supply-gated`; author-described assets `mapped`, exact experiment/CFD counterparts `missing-exact-leaf`, repository candidate code/manifests `path-confirmed`, raw media `not-covered`; metric `N/A: qualitative morphology only`; render `blocked`; disposition `fallback-only` through schematic-only to complete omission. No publication-ready claim is permitted. Caption ceiling is unregistered single-frame morphology under named open-loop conditions only.

## Current evidence mismatch

The author reports that an apparatus schematic and single-frame experimental/CFD pairs exist, but targeted inspection did not locate those exact files. CelerisLab contains CFD action, streakline and vorticity generation code plus manifests that point to generated computational images; the referenced image/checkpoint files were absent from the inspected output directories. No physical execution/deployment script or experiment-media provenance package was located. Thus no panel is presently publication-ready, and no manifest path may substitute for the author's exact corresponding files.
