Tutorial five-board screenshot provenance — 2026-08-28

This record covers the Lenovo-only, five-board app captures prepared for local review of the ten-part learning path. Technical integrity and privacy review are complete. Final content approval and production publication remain separate actions.

Capture environment

• Capture date: 2026-08-28 (Asia/Bangkok; the UTC date was also 2026-08-28)
• Physical capture device: Lenovo TB-J616X
• ADB serial and transport: HA1HM0X8 over USB; wireless debugging was not enabled
• Operating system: Android 12 (API 31)
• App surface: PyBLE 0.2.0 beta, build 5
• Capture-only package: dev.pyble.pyble.tutorialcapture
• App source revision: 4df378fc76c919f0e2481eb5b668f14115d38587
• Capture APK SHA-256: ad0a15a5f7f80005aac86f422ac53b888162fbca2b96920f4eacf1f1819fc679
• PyBLE agent version on every connected board: 0.6.0
• Raw directory (ignored): ScreenShots/tutorials/android/lenovo-tb-j616x/0.2.0-beta/five-boards/
• Reviewed directory (ignored): ScreenShots/tutorials/android/lenovo-tb-j616x/0.2.0-beta/five-boards/reviewed-tutorial-set/
• Processor: ImageMagick 7.1.2-21 Q16-HDRI aarch64

The release-mode capture package used a disposable local signing key and a capture-only application ID so it could coexist with another installed build. It is not a distributable release artifact. The key and generated build output remain outside Git.

No iPad was used in this capture workflow. App installation, interaction, and ADB capture targeted only the Lenovo tablet. The laptop-side processing and review used only Lenovo raw inputs; no iPad capture entered the set. The Lenovo stylus overlay was stopped before every selected raw frame. No selected derivative contains the stylus affordance.

Five-board session map and evidence boundary

The stopped discovery frame records exactly five distinct advertisements and Scan: Idle. An advertisement proves only that a nearby PBLE agent advertised; it does not prove installed firmware-profile bytes. Each connection frame records a Ready status with board ID and agent version plus a read-only runtime token.

Advertisement / board ID	Maintained physical-session context	Captured state	Captured runtime token	Evidence boundary
PyBLE-5646 / 5646	Generic ESP32-S3 N16R8, explicitly confirmed by the user	Ready / agent 0.6.0	esp32-s3	The user-supplied physical context identifies this board; the runtime token alone is not generic-profile proof.
PyBLE-8C9E / 8C9E	Generic/classic ESP32 session	Ready / agent 0.6.0	esp32	The app does not prove flash capacity, carrier, pin map, or installed profile bytes.
PyBLE-C81A / C81A	Generic ESP32-C3 session	Ready / agent 0.6.0	esp32-c3	The app does not prove flash capacity, carrier, pin map, or installed profile bytes.
PyBLE-DA86 / DA86	Waveshare ESP32-S3-LCD-1.47B physical-session context	Ready / agent 0.6.0	esp32-s3	The maintained physical-session context identifies the exact board; the runtime token alone does not prove the carrier or Waveshare profile.
PyBLE-3DCB / 3DCB	Raspberry Pi Pico 2 W physical-session context	Ready / agent 0.6.0	rpi-pico2-w	Exact-board/profile evidence remains the physical marking and installer record, not the token alone.

The 5646 and DA86 runtime derivatives intentionally have identical pixels and the same SHA-256. That is expected evidence: both sessions report only esp32-s3 at this layer, so the app cannot distinguish their provisioning profiles. The paired Ready and runtime derivatives are composed by semantic HTML/CSS; no raster collage was produced.

These observations are tutorial-documentation evidence only. They are not PBLE conformance, firmware release qualification, installed-byte proof, or GPIO, display, wiring, electrical, or other hardware-in-the-loop evidence. No GPIO or display behavior was exercised or qualified during this capture pass.

Deterministic processing

process-tutorial-captures.sh validated all 13 distinct raw images as one 2000×1200, 8-bit PNG each and produced 18 derivatives:

Derivative class	Distinct raw frames	Derivatives	Exact crop
Full app frame	8	8	2000x1092+0+36
Connected Ready status	5	5	400x84+0+36
Connected read-only runtime panel	Same 5 connected frames	5	512x390+1488+330
Total	13	18	Three fixed geometries

The full-frame crop removes 36 pixels of Android status bar from the top and 72 pixels of Android navigation area from the bottom. The processor crops the two identity regions independently from each connection raw, strips metadata, forces 8-bit PNG output, excludes date/time chunks, and uses fixed PNG compression settings. It does not resize, annotate, blur, recolor, generate, or retouch app pixels. Every output passed an exact crop comparison with zero changed pixels.

The review directory contains an 18-row SHA256SUMS, a deduplicated 13-row SOURCE_SHA256SUMS, and the 18-row tutorial-captures.tsv used for the table below. Reviewed filenames contain the app version, build, stable key, and first 12 characters of the reviewed digest.

Interaction, writes, and cleanup

• The five-board scan was allowed to settle, then stopped before capture. It showed the five intended advertisements and Scan: Idle.
• 5646 was used for read-only identity and GitHub browsing/review frames. No GitHub file was downloaded to that board.
• On 8C9E, /tutorial-capture/hello.py was created with 26 bytes and run once. The program was a hardware-free Console greeting. Two empty disposable files, /tutorial-capture/delete_me_one.py and /tutorial-capture/delete_me_two.py, were then created for the exact permanent-delete review. The confirmation shown in the selected frame was canceled and both files remained. A second selection of the same exact two files was then confirmed; only those two named disposable files were deleted. /tutorial-capture/hello.py and its folder were retained.
• On C81A, /tutorial-capture was created and the Hello PyBLE Blocks starter was opened in the editable workspace. It was not saved to the board and was not run.
• On DA86, /examples was created and pyble_hello_console.py was imported from the public examples repository at immutable commit 8f4529b3cd0d62e8d53d7deb4f37e5cd2a171fd1. The imported file was not opened or run.
• 3DCB was used only for read-only connection identity.
• The app was left disconnected after the capture session. No other board file was created, overwritten, or deleted as part of the selected workflow.

Technical and privacy review found no account, token, private repository, notification, personal filename, debug label, integration-test label, or unrelated board file in the selected derivatives. The public board IDs, official examples URL, immutable public commit, tutorial source, and named disposable tutorial files are intentional instructional evidence.
