Last 90 days: 6 pinned values changed in 6 commits; docs changed in all of them

[bb4rjfl]

Hi hyperdxio team. I ran hyperdx's last 90 days of commits (443) through a tool that pins "values the code promises" (291 constants, enums and config fields) and watches when they change. Just the numbers:

date	commit	value	change	docs changed in the same commit
2026-08-10	05a3fd8	packages/api/src/models/alert.ts#AlertState	+ERROR	yes
2026-08-28	df4a7a5	packages/api/src/models/alert.ts#AlertSource	+inline	yes
2026-10-06	6873416	packages/api/src/routers/external-api/v2/utils/alertChartConfig.ts#EVALUATION_INERT_CONFIG_KEYS	+heatmap	yes
2026-10-07	68082b6	packages/common-utils/src/types.ts#DisplayType	+stacked_line	yes
2026-10-19	af6e7f6	packages/api/src/routers/external-api/v2/utils/alertChartConfig.ts#EVALUATION_INERT_CONFIG_KEYS	+description	yes
2026-10-19	0000fa4	packages/api/src/routers/external-api/v2/utils/alertChartConfig.ts#EVALUATION_INERT_CONFIG_KEYS	+lineInterpolation	yes

All 6 commits that changed a pinned value also touched a Markdown file — that's rare, and it's exactly the discipline a check can keep for you the one time someone forgets.

I'm building MergeGate, a GitHub check that catches exactly this on every PR: next to a sentence in your docs you declare one line (source: path#SYMBOL, expect:); a PR that changes the value gets a 🔴 (and can block the merge if you opt in), and if the code is right a button opens a PR that rewrites the doc. No LLM in the verdict.

Free for public repositories. Installing it posts the full version of the table above as an issue: https://github.com/apps/mergegate-checks/installations/new · how it works: https://mergegate.tacita.cloud/en

If this isn't welcome, please close the issue — I won't post again. The table came from a git clone --shallow-since of public history; nothing was written to the repository.
