File timestamps can't see staleness that comes from outside the folder: what an agentic housekeeping routine needs that mtime doesn't give it

My weekly routine rebuilds stale project summaries by comparing file modification times. It ran clean — and missed a summary made wrong by a decision taken in a different folder. Local change detection is not correctness.

A counted conversion with a made-up value is worse than no tracking: the flat €10 add-to-cart that flattered four markets' CPA

A soft add-to-cart event carrying a flat €10 value, set as a primary conversion action, had been training Smart Bidding for weeks. Fake tracking is more dangerous than no tracking — here is the order in which to fix it.

Why talking-head video looks scripted: finding gaze and repetition mechanically in the edit

Two notes on a dental-hygiene course reel turned into a repeatable method: eye-region contact sheets to locate every glance off-lens, and per-segment transcription so captions land on the take you actually kept.

The daily automation that never calls a model: local scheduled jobs, a receipt printer, and designing for the device being offline

Claude Code built it; nothing in the running loop calls a model. The useful lesson was not the printer - it was that the output device is the flakiest link, and coupling the email to the print cost me both.

“Other products” is a measurement defect, not a category: recovering product names from a SKU-only revenue report

A catch-all line on a performance dashboard turned out to contain an entire product launch, because one channel reported revenue by SKU and never by name. How the mapping was recovered, and why a residual bucket should document itself.

Attribution only gets real when it joins the order book: matching four months of web enquiries to the ERP

Joining website enquiries to an ERP's quotations and confirmed orders is an entity-resolution problem, not a VLOOKUP. What the match ladder, the company-level unit of attribution and an eighty-day lag tail do to your read on lead quality.

Price governance in ecommerce: how a promotion died silently on four country shops for a month

A home and living brand advertised a fifty-euro saving while checkout charged full price on four markets for a month. The cause was the price guard itself - and the fix was declaring the price once and auditing the whole chain daily.

I put client KPIs on an e-ink screen instead of a dashboard nobody opens: why the artifact couldn't go there and a webhook could

The dashboard was fine. Opening it was the problem. Here is why a private, JavaScript-driven page can't go on an e-ink display, why I fed the screen from the pipeline that already existed, and why refresh rate is a claim about your data rather than a setting.

An expired promotion doesn't expire by itself: the ended sale still on the shop, the promotion asset still serving a 404

Four country shops still displayed a twenty-euro saving three weeks after the sale ended \u2014 while the cart charged full price. In the same week, promotion assets with no end date were still pointing at a removed landing page. A promotion is a set of artefacts, not a date.
