Evidence

Seven entries. Steps to verify are literal: try them, and if something doesn't hold up, that's a defect worth filing.

notchplayITEM 01

VerifiedOpen source

Apple Music and Apple Podcasts now-playing info and transport controls, in the MacBook notch itself. On a display with a physical notch it sits as a compact pill beside the camera housing and expands to a full player on hover.

On a display without one (an external monitor as main display, say) it draws a simulated notch: a persistent bar pinned to exactly menu-bar height, with artwork, title, artist, and three transport controls visible the whole time something plays.

Steps to verify

Open the repository and read the source. All of it is there.
Build it. Play something in Apple Music.
Look at your notch.

github.com/jeffbuildsdotdev/notchplay → Download .app (v1.0.1, unsigned) →

Platform: macOS, Apple Silicon
Sources: Apple Music + Apple Podcasts only. Never browsers.
Chrome: No Dock icon, no menu bar item (LSUIElement)
License: Open source, public repo

missionquitITEM 02

VerifiedOpen source

Quit an app from inside Mission Control: click the ✕ on its window, or hover the window and press Q. Either way the whole app quits, not just that window, and Mission Control stays open so you keep going.

No Dock icon, no menu bar item. It does the one thing Mission Control always looked like it should do.

Steps to verify

Open the repository and read the source. All of it is there.
Build it. There's a build.sh, and it does what it says.
Open Mission Control. Hover a window, press Q.

github.com/jeffbuildsdotdev/missionquit → Download .app (v1.0.0, unsigned) →

Platform: macOS 26 Tahoe, Apple Silicon
Surface: Mission Control itself, not a floating overlay
Chrome: No Dock icon, no menu bar item
Repo: github.com/jeffbuildsdotdev/missionquit

Air LetterITEM 03

VerifiedLive

Gratitude is two-sided, so the app is. Write an entry, optionally name the person, send it. They open the link and it lands in their Received column.

No accepting. No accounts. Nothing reported back to you.

Steps to verify

Open airletter.co.
Write something you actually mean. Send it to the person it's about.
That's it. That was the whole product.

airletter.co →

Platform: Web, live in production
Accounts: None
Telemetry to sender: None, deliberately
URL: airletter.co

Air Letter as it looks live: three columns labeled Before, Today, and Received, with a letter-writing form in the middle — FIG. 3 · Live capture · airletter.co · 2026-08-23

Rep SheetITEM 04

VerifiedLive

An in-session workout set logger with zero friction: one tap logs weight, reps, RPE. Built for the ninety seconds between sets, when a form with a submit button is ninety seconds too long.

Static PWA, no backend, no accounts. The author logs his own real training sessions with it. That's the entire user base so far, and it works for him.

Steps to verify

Open repsheet.jeffbuilds.dev, ideally mid-workout.
Log a set. Count your taps.

Declared, not claimed: an AI plan-generator phase is planned and not built. It's listed here so it can never quietly become "shipped."

repsheet.jeffbuilds.dev →

Platform: Static PWA, installable
Backend: None
Accounts: None
In use: Author's own training, real sessions

Rep Sheet as it looks live: the plan entry screen with a text area for typing exercises one per line, plus Load sample plan and Start session buttons — FIG. 4 · Live capture · plan entry, one tap from a session

Channel Reality CheckITEM 05

VerifiedLive

Subscriber count is a vanity metric. This shows what a YouTube channel's videos actually do: median views on recent long-form uploads, split apart from Shorts, which monetize at roughly a tenth of the rate. Plus four 0-100 scores: discoverability, momentum, consistency, revenue potential.

Single-file Cloudflare Worker, no framework. It runs on the YouTube Data API's free tier and fails closed on quota exhaustion rather than incurring cost. This was the first piece of software the author ever shipped, built in one day.

Steps to verify

Open channel-reality-check.jeffbuilds.dev.
Paste a channel you have opinions about.
Compare what it tells you with what the subscriber count implied.

channel-reality-check.jeffbuilds.dev →

Stack: Single-file Cloudflare Worker, no framework
Data: YouTube Data API, free tier
Quota policy: Fails closed. Never incurs cost.
Provenance: First shipped project. Built in one day.

Channel Reality Check as it looks live: a printed findings-sheet layout with a channel URL field, a Check button, and four ruled 0-100 score bars for discoverability, momentum, consistency, and revenue potential — FIG. 5 · Live capture · channel-reality-check.jeffbuilds.dev · 2026-08-27

Content EngineITEM 06

DemonstratedOn request

Drop in a topic. An SEO-structured post comes out the other end in Google Docs, unattended. n8n orchestration, OpenRouter inference, running on a small VPS.

Built as a portfolio piece: it exists to show contract clients what a finished automation pipeline looks like, not to be a consumer product. So there's no public URL, and this entry says so instead of pretending otherwise.

Verification limits

Not publicly hosted. Demonstrated on request to prospective clients: bring a topic, watch the document arrive.

Orchestration: n8n
Inference: OpenRouter · DeepSeek V4 Pro
Output: SEO-structured post, delivered to Google Docs
Infrastructure: Hetzner VPS
Operation: Unattended

FIG. 6 · Topic in, document out

Family HubITEM 07

In usePrivate

A kitchen display on a Raspberry Pi 5: Python, Home Assistant integration, touchscreen mounted on the wall. It runs the household's chore system, calendar, school lunch info, weather, and smart-home device chips.

This one has the harshest QA environment on the list: a family that did not ask to be beta testers and files defects verbally, at breakfast.

Verification limits

Family-internal, and staying that way. No link, on purpose. Recorded as: in daily production use, on a wall.

Hardware: Raspberry Pi 5, wall-mounted touchscreen
Language: Python
Integration: Home Assistant
Users: The household, daily

Appendix: minor artifacts

Small utilities that shipped but don't warrant a full evidence entry. No stamps, no figures, no spec tables. Logged so they're on the record, and so future ones have somewhere to go.

A1 mirror A macOS menu-bar camera preview: click the camera icon, get a floating panel, check yourself before a call. Swift, AVFoundation, no Dock icon. Built and in use on the author's machine. BUILT · NOT PUBLIC

A2 pixelplane A macOS overlay that flies a pixel-art airliner across the desktop while a tracked flight is in the air: position matches live flight progress, label carries the delay status. Click-through, invisible between flights. Swift, live flight-data API, sprite generated by a purpose-built Python renderer. Built for one very specific user's travel days. Source at github.com/jeffbuildsdotdev/pixelplane. BUILT · OPEN SOURCE

FIG. A · Panel A drawn, not a capture, no real face · Panel B is the app's actual generic-livery sprite, no real flight

Subject under test

QA engineer by day, at (withheld on purpose). Ships his own software by night. That combination is why this page is shaped like a test report: verifying claims is the day job, and the day job does not switch off.

Off-screen, the same habit with different materials: renovation, electrical work, building things you can lean on.

The range table is derived from the evidence above. It claims nothing the seven items don't already show.

Observed test environments

Swift · native macOS items 01, 02
Cloudflare Workers item 05
Web · PWA items 03, 04
n8n + OpenRouter automation item 06
Python · Raspberry Pi · Home Assistant item 07

Instrumentation

Pair tooling: AI-assisted throughout. Claude Code as the primary.
Second opinions: A second local model rig, consulted where agreement is worth little.
Scope: Orchestrates the same stacks the environments table lists. Detail kept coarse on purpose.

The tooling drafts. Shipping still has to happen.

Verdict

Seven items, five of them one click away, two declared with reasons instead of dressed up with fake links. As far as this report can tell, the claim holds.

A report that grades its own author deserves a raised eyebrow, which is exactly why the links exist. Don't take the stamp's word for it. Click through and grade it yourself.

PassPending your review

Reviewer sign-off

This report benefits from independent review. That's you. Three ways to countersign:

ContractOpen to interesting contract work: automation, API integrations, pipelines. Item 06 is the audition tape.
Co-buildOpen to co-building and open-source collaboration. Item 01 shows how the code looks when it ships.
DefectsHonest feedback on anything shipped is wanted, not merely tolerated. File defects. Seriously.
