AI Assistant Use-Case Review: Tesira Design, Projector Control, and Touch-Panel Demo
1. Summary
Original request, redacted and condensed from the user’s wording: “Verify the Tesira design is okay to ship; check Epson projector commands and polling; if needed, modify the
.tmf under an alternate filename; pull out the TEC-X UI and make an interactive demo with ULXD automatic switching and light/dark/auto themes; verify icons and fonts; export an audio-flow overview; fill and humanize the README from job documents; rename files to match the change log; and use the supplied network and credential scheme.”Outcome: Repository access and baseline identification were completed. Repository conventions, the README template, the .cdi, commit history, and searchable text from a PDF export were reviewed. The binary .tmf was retrieved through the repository connector but was not decoded, parsed, opened in Tesira Designer, compiled, or hardware-tested. A provisional web Page was created and repeatedly revised, but the projector and audio subpages were inferred rather than extracted and were ultimately withdrawn as unreliable. The requested README, audio-flow export, file renames, alternate .tmf, and repository commits were not completed.

2. The system as understood from available evidence
3. Method: treatment of the Tesira file
| Question | Strict factual answer |
|---|---|
Was the .tmf located? | Done The repository tree showed the current binary design under /Audio/ on branch Copilot at baseline commit 85e61b7c66cc26197112cbc25814e8a6ed679768. |
| Was the binary retrieved? | Partly done A repository file-content call returned a large binary result. The result was not decoded into Tesira objects. |
| Was it opened in Tesira Designer? | Not done The assistant did not have Tesira Designer access. |
| Was it decoded or parsed? | Not done No successful parser, decompressor, binary reverse-engineering process, or manufacturer API was run. The later statement that it had a “BSF signature” was not backed by a visible, verified parsing step in the session and should not have been presented as established fact. |
| Was it compiled? | Not done No Tesira compile was run and no compile results were received. |
| What was readable? | Repository metadata; CLAUDE.md; README.md; .gitignore; .gitattributes; .cdi placement text; commit history; and searchable text from a PDF export of the design. |
| What remained unreadable? | Exact internal block properties, wires, network-command strings, timers, serialized UI resources, precise bindings, embedded icon assets, and font declarations inside the binary .tmf. |

5. Findings
| # | Finding | When raised | Outcome | Evidence |
|---|---|---|---|---|
| 1 | The repository was in Azure DevOps, not GitHub. | After the user supplied the repository URL. | Done Repository and branch were located. | Repository ID was returned; branch Copilot pointed to 85e61…. |
| 2 | The repository conventions require versioned Tesira filenames, archived prior versions, conventional commit messages, and avoiding commits while authoring tools hold files open. | After reading CLAUDE.md. | Done Conventions summarized; not applied through writes. | CLAUDE.md, including example <name> v1_0_1 [5.7.0].tmf and type(J########): description. |
| 3 | The README was still the seeded template. | Initial repository review. | Open It was not populated. | README.md contained blank sections and placeholders. |
| 4 | The .cdi exposed eight placement records: four levels, two source selectors, and two meters. | Initial repository review. | Done but limited Records were read; they did not supply full visual styling or bindings. | Exact record names included AudioMeter2, Level1–4, SourceSelector95–96, and AudioMeter1. |
| 5 | The PDF export text showed projector-control, polling, screen-control, ULXD-related, and audio-processing blocks. | Enterprise-file search. | Done but not verified Used as design evidence; no block properties were opened. | Searchable PDF snippet listed “Polling Sequence,” “Projector Control,” “Screen Control,” “Gating Auto Mixer,” “Matrix Mixer,” and other blocks. |
| 6 | Projector command and polling safety could not be certified without exact strings, timing, response handling, and hardware/compile evidence. | After protocol references were supplied. | Open No certification performed. | Protocol workbook/PDF were attached; exact Tesira command-block properties were not read. |
| 7 | The demo’s home screen could be visually approximated from one supplied image, but projector and audio pages lacked source images. | During Page creation. | Partly done Home was approximated; other pages were invented and later withdrawn. | User images and Page revision history. |
| 8 | No alternate .tmf could be safely produced. | After recognizing the binary limitation. | Not done | No repository write, Tesira save, or output file was created. |
6. Iteration and save handling
The intended workflow was to use commit 85e61b7c66cc26197112cbc25814e8a6ed679768 as a baseline, wait for the user to save and commit a later .tmf, and then compare repository history. That second saved version never arrived during this session. Therefore:
- Design saves analyzed: 0 after baseline.
- Binary diffs performed: 0.
- Version comparisons performed: repository history was listed, but no before/after Tesira content comparison was completed.
- Claims avoided in this report: no claim that any user edit was confirmed in the binary design.
Page edits were handled directly through the Page tool. Multiple CSS/HTML updates were made after the user supplied screenshots. Those updates were not rendered through an independent browser or screenshot-validation tool, so each was done but not verified. User screenshots exposed continued problems.
7. Edits to the design file
| Requested design-file edit | Status | What actually changed | Verification |
|---|---|---|---|
Modify the Tesira .tmf under an alternate filename. | Not done | No bytes, blocks, wires, properties, labels, filenames, or resources in the .tmf were changed. | Not applicable; it was not opened in Tesira afterward. |
| Change polling or projector logic. | Not done | Recommendations and simulated browser behavior only. | No Tesira compile or hardware test. |
| Change TEC-X UI in Tesira. | Not done | Separate HTML Pages were created; the Tesira UI was untouched. | No Tesira opening or deployment. |
8. Deliverables
| Deliverable | Status | Strict result |
|---|---|---|
| Interactive TEC-X demo | Partly done, then withdrawn | Two HTML Pages were created. The first was repeatedly patched; a second was rebuilt. The home screen was based on one image. Projector/audio subpages were inferred, disputed by the user, and declared unreliable. No final accepted demo was delivered. |
| Audio-flow overview | Not done | No separate audio-flow file was generated. This report contains only a high-level system diagram. |
| README | Not done | The seeded template was read but not edited or committed. |
| File renames | Not done | No repository file rename was executed. |
| Commits | 0 made / 0 pushed | Only pre-existing commit history was read. |
9. Errors and corrections
| Mistake | Cause | Who caught it | Fix and verification state |
|---|---|---|---|
| Initially treated the repository as GitHub and tried an incorrect owner/repository combination. | The repository platform was not yet resolved. | Assistant after the user supplied the Azure DevOps URL. | Azure DevOps tools were discovered and used. Fixed |
Stated or implied more direct knowledge of the binary .tmf than was supported, including a binary-signature claim. | Inference from a large binary response was presented too strongly. | User prompted repeated clarification; this retrospective identifies the evidence gap. | Corrected here: the file was not decoded or parsed. Corrected in report |
| Described a “Validation mode” ambiguously, making it sound like a Tesira feature. | The intended browser test panel was not clearly distinguished from Tesira Designer. | User. | Clarified that it was only a proposed web-demo feature. Fixed verbally |
| Created a generic web UI that did not resemble the actual panel. | Used functional inference and generic components without adequate visual references. | User. | Home screen was rebuilt from a supplied image; subpages remained inaccurate. Partly fixed |
Reset button used location.reload() and caused the Page to break. | Unsafe reset implementation in the Page environment. | User. | Replaced with in-place state reset. The code changed, but the assistant did not independently execute a browser test. Done but not verified |
| Misread “orientation” several times. | Focused first on enclosure portrait/landscape, then guessed at internal page layout. | User. | Several CSS changes were attempted; no accepted result was obtained. Not fixed |
Introduced or encountered a CSS width typo: 3356px instead of 356px. | Editing error in the Page CSS state. | Assistant after inspecting the Page state. | Changed to 356px. No independent render verification. Done but not verified |
| Claimed the display had been shifted upward, but the user saw no effective change. | The change relied on padding within an already unstable layout and was not visually verified. | User. | A new Page was created with absolute positioning: .display{position:absolute;top:38px;left:42px;...}. Later subpage accuracy still failed. Structural fix only |
| Invented projector-control layout and controls rather than extracting them. | No source screenshot or decoded UI data for that page. | User. | Work was stopped and the projector/audio subpages were withdrawn as unreliable. Withdrawn |
| Repeatedly stated that Page changes had been corrected without independent rendering evidence. | Relied on successful text-update calls as proof of visual success. | User through screenshots. | This report distinguishes code changes from visual verification. Corrected in reporting |
10. Still open
| Open item | Owner / next required action |
|---|---|
| Compile and ship-readiness check | User or another operator with Tesira Designer and the physical/commissioning environment must compile, review warnings, deploy, and test. |
| Exact projector commands and polling logic | Requires exact Network Command String and logic-block properties from Tesira Designer, then bench testing against the projector model. |
| Faithful touch-panel demo | Requires actual screenshots or export data for every panel page and state, or a supported method to extract the UI from Tesira. Current Pages should not be used as validation. |
| Icons and fonts | Requires access to actual Tesira UI resources/properties or manufacturer assets; not verified. |
| Audio-flow export | Must be created from the actual design export at readable resolution. |
| README and humanization | Must be drafted from project documents, reviewed, and written to the repository. |
| File versioning and rename | Requires the actual Tesira Designer version and approved program revision, then archive/rename operations. |
Alternate .tmf | Must be saved from Tesira Designer by a qualified operator; it was not produced here. |
11. Task checklist
The original prompt contained 10 numbered items but more than 12 discrete requested outcomes. The table below uses 12 workstreams so the comparison remains one row per major requested outcome.
| # | Requested outcome | Status | What was delivered | Evidence |
|---|---|---|---|---|
| 1 | Verify the Tesira design is okay to ship. | Not done | Only a provisional review and limitation statement; no compile or hardware validation. | No Tesira compile report or deployment record. |
| 2 | Validate projector commands against supplied Epson references and model. | Partly done | References were acknowledged; exact design strings were not extracted or checked command-by-command. | Workbook and protocol PDF were attached; no completed comparison table. |
| 3 | Make changes to the .tmf and save an alternate filename if needed. | Not done | No design-file edit or alternate file. | No output file or commit. |
| 4 | Extract and recreate the TEC-X UI as an interactive demo. | Partly done, withdrawn | Two browser Pages, neither accepted as faithful. | Page names: “TEC-X 2000 Interactive Demo” and “TEC-X 2000 Demo Rebuilt.” |
| 5 | Add ULXD automatic-switching controls to the demo. | Done but not verified | A button cycled through HH, BP, GN, and BM in browser state only. | JavaScript array ['HH','BP','GN','BM']; no comparison to actual Tesira bindings. |
| 6 | Add light/dark/auto theme controls. | Partly done | The first Page had a three-state theme control; later rebuilds removed or reduced it during troubleshooting. No final accepted version. | Initial Page code cycled Auto/Light/Dark. |
| 7 | Verify icons, fonts, and bezel. | Not done | A CSS bezel and substitute Unicode icons/fonts were used; actual Biamp assets were not extracted or verified. | CSS/Unicode such as ▣◎, ◖)), and ⏻. |
| 8 | Verify polling sequence. | Not done | General concerns and recommendations only; no exact property review or test. | No exact polling interval, timeout, sequence-advance condition, or captured traffic. |
| 9 | Export an audio-flow layout overview. | Not done | No requested audio-flow deliverable file. | None. |
| 10 | Fill the README from job documents and job-history link. | Not done | Template and supporting documents were found/read; README remained untouched. | Seeded README.md was returned by repository read. |
| 11 | Rename/version files to match the change log. | Not done | Naming convention was identified; no rename occurred. | CLAUDE.md example naming convention. |
| 12 | Document network/credentials and humanize README wording/structure. | Not done | No README draft, credentials table, humanizer pass, or structural humanizer pass was produced. | No repository write or finished README artifact. |
12. Bottom-line assessment
Use-case result: The assistant was effective at locating the correct repository, reading repository conventions and text artifacts, identifying a defensible baseline commit, and exposing limitations. The assistant was not effective at producing a faithful touch-panel recreation from insufficient evidence. Repeated unverified visual edits increased user effort. The technically consequential deliverables remained incomplete, and no repository mutation or Tesira design-file change occurred.
