From Research to Solutions

These tutorials document real problems I encountered during development, the research behind finding solutions, and code snippets that worked in production. I'm proud to share what I've learned to help others facing similar challenges.

Documented Learning

Each tutorial represents hours of research, trial and error, and real-world application

Production-Ready Code

Code snippets and patterns proven in actual projects, not theoretical examples

Cloud MigrationJira

Jira automation rules do not migrate themselves

JCMA brings your rules to Cloud disabled and without their actors. Cloud-to-cloud brings nothing at all. Measured on a live Cloud site: the Rule Management API's 400s that name no field, the app-actor discovery our own runbook got wrong, and the scope ARI the API silently rewrites behind your back.

LeanZero Management: virtualising a 5,300-issue Gantt

A 5,300-issue plan put 94,920 nodes in the DOM. Windowing the rows took it to 2,115 — and left a second full-height layer that windowing does not touch.

Locking in Forge KVS: FAIL_IF_EXISTS works, TTL leases do not

Forge does have an atomic create-if-absent, and it holds under concurrency. Add a TTL to turn it into a lease and it stops being one. Measured on a deployed app, with the manifest and code for the pattern that actually holds.

forge lint cannot see your request helper: the Jira scopes it never checks

forge deploy now blocks on lint errors, so the scope linter has quietly become a gate. It only reads endpoints written inline — one request helper hides every call in your codebase. Measured on @forge/cli 13.4.0, including what the runtime actually returns when a scope is missing.

Clearing the Done column in Jira Cloud: company-managed vs team-managed

The manual Clear Done work items button is gone from team-managed boards, and company-managed boards never had it. They have something better, and I measured it: a released version empties the Done column for everyone in under 15 seconds.

LeanZero Management: two scheduling engines, one schedule

A Forge PPM app needs a live in-browser scheduler and a server-side one. They drift by a day, no test goes red, and the user believes the preview. Here is the harness that catches it — and the two mutations I ran to prove it works.

jira:workflowCondition vs jira:workflowValidator: one runs your code

We shipped both modules in CogniRunner pointing at the same handler. Only one of them ever invoked it. forge lint says No issues found, forge deploy validates the manifest and passes, and the gate you built is permanently open with zero log lines. Here is the probe app that proves it, and the two things that actually work.

Auditing a Jira Migration: a Wrong Field ID Counts to Zero, Not to an Error

Jira Cloud answers a JQL query about a custom field that does not exist with HTTP 200 and a count of zero. In a post-migration field audit, zero is the number that authorises deleting the field. I swept all 197 custom fields on a live site to find out which gate actually catches it.

Surviving Atlassian's points-based rate limits in a Forge app (2026)

Since March 2, 2026, a Forge app shares one 65,000-point hourly pool across every install. Ours spent it by 18 minutes past the hour. Here's the metering, the count tripwires and the self-imposed budget that took a 13,500-user Confluence estate down to ~2,000 points in a quiet hour — without a bigger quota.
