Onboarding, and a local build that fought back
Standard first week: setup, orientation sessions, first one-on-one with my manager, and reading the project scope. I cloned the repository and started working through the platform's replication and content-model documentation.
My first attempt at the local environment got tangled badly enough that restarting from scratch was faster than untangling it. Logged that as a loss rather than quietly redoing it, which turned out to be the right instinct: the second attempt was clean and I understood why.

The feature already existed, so the project changed shape
Got the local environment fully running, then walked the authoring interface the way an author would rather than the way a developer would, looking for what was missing.
The most useful finding of the internship came out of that: the editor bar I had been scoped to build already existed. The project was extend, not build from scratch. That reframing saved rebuilding something already in production and it changed every design decision that followed.
With that settled I wrote the design document end to end, built three architecture diagrams, and put together a risk register and an open-questions list so the unknowns were visible instead of implied.

First design review, and scoping the hard part down
Documented the full codebase map so the next person would not have to repeat the reading, and rebuilt the research document after losing it to a tooling error.
Made the first real scoping decision of the project: took the most complex signal down to a minimum viable version and deferred the harder variant, so the first release could actually land inside the internship.
First design review with my mentor produced five discussion points. I worked all five back into the document and verified each one against the codebase rather than accepting them on faith.
Also sat in on an operational postmortem review for an unrelated service. Worth the hour purely to see how the team separates root cause from symptom and how the writeup is structured.

Design document approved, mockups built in two tools
The design document was completed and reviewed with the team, which was the week 4 deliverable.
Built an interactive mockup of every badge state plus the acknowledgment dialog in HTML and CSS, then rebuilt it in Figma so the design conversation could happen in the tool the designers actually use. Cross-checked both against the numbered requirements in the design document so nothing was mocked that was not specified, and nothing specified was missing.
Also spent time on tooling: wired up a design-to-code integration and extended my own logging tool to capture work sessions automatically instead of relying on memory at the end of the day.

Team design review: 38 comment threads, 29 edits applied
The big review week. The team design review generated 38 comment threads, which I triaged into themed discussions and turned into 29 concrete edits, all of them applied and checkmarked in the document.
Rebuilt the mockup a third time against that feedback: click-only interaction instead of hover, and a production-fidelity pass that pulled real colors and bar classes from the shipped stylesheet so the mockup would transfer directly to implementation. Seven states in total.
Then a consistency pass across all three project documents, 14 edits, so the design document, the research document, and the talking points agreed with each other. Spent the rest of the week on the backend approach: sketched the response contract and wrote out the failure modes before writing any code.

Out sick, so the week went to documentation
Sick for most of the week with no implementation progress, which I logged as a loss rather than padding it into something better.
What did get done was low-energy and useful: a mapping of where each design requirement lands in the code, a mockup pass on the two edge-case states, and the midpoint self-review form. Breaking the remaining work into tracked subtasks meant the second half started with a plan instead of a blank page.

Four sequential code reviews, and the first one written
Planned the implementation phase as four sequential code reviews rather than one large change, so each would stand on its own and review independently. That decision shaped the rest of the internship.
Started the first one: the read-only backend endpoint that resolves the verdict. Drafted the test matrix before writing the tests, wrote the sync-status and attribution logic by hand, then did a self-review pass reading my own diff specifically looking for my own bugs before anyone else saw it.
Ended the week with the full project running locally and the endpoint verified against a live instance rather than only against mocks. Two build artifacts were unavailable to me, so I stubbed them locally instead of letting the build block the week.

Review rounds one and two, and eight real defects
The first review landed and I worked it properly: findings written up with severity, file and line, reproduction, and a one-line fix each, then verified with the full suite green.
Then I ran an adversarial review pass on the second change and found eight verified defects, one of them a genuine correctness bug where a failure path could have produced a confident wrong answer instead of a neutral one. I also recorded the eleven candidate findings that the pass raised and I then refuted, so the next reviewer would not spend time re-raising them.
That habit of writing down the refuted findings alongside the real ones turned out to be the most useful reviewing thing I did all summer.

All four reviews stacked, configuration and observability in
Raised the remaining three changes as a stacked chain so each one reviews as a self-contained change while building on the one below it.
The second change added the editor surface: the badge column inside the existing bar, one request per editor load under a hard deadline, and a fail-open path on every error so a timeout or a malformed response renders a neutral badge with a retry rather than a fabricated verdict.
The third added the on-demand review panel and the acknowledgment step: a dialog showing the drift timeline, the changed-component list with links into the editor, and an explicit acknowledgment. Nothing opens on load, viewing never acknowledges, and closing never acknowledges. Its review produced sixteen findings across three severities, and all three of the top-severity ones were the same class of problem: the acknowledgment could assert a state the system had not actually verified.
The fourth turned every hard-coded constant from the first three into configuration, added structured logging and an end-to-end test, and wired the feature flag explicitly across every environment so production records its off state rather than inheriting a default.
Also made a naming decision I would defend in any review: registered the endpoint under the editor surface rather than under the feature name, because the bar is only one consumer of the contract and grouping by surface leaves room for the others.
