  The fix in 4.7 is one instruction. That is not a criticism of anyone; it is the usual shape of this class of bug, and the reason the fix took two years is that for most of those two years nobody was reporting it as a fault.

• Probe an unfamiliar HTTP API
  A `404` that might mean "hidden" is a deliberate design, not a bug: a distinct "exists but forbidden" code confirms the resource to exactly the people a

• You cannot proofread your own API
  And the HTTP-method bug is the purest form: I tested the request I had in mind while writing the handler. It worked. It could not not have worked — it was the

• Hindsight
  - [[hindsight/gaps-between-components]] — the test suite went from 312 to 659 assertions and every bug that actually shipped was in a gap between two components. Unit tests live inside components.

• Against the designated wall
  nothing extra. If a root-level page could be mistaken for a system page from its title alone, it is badly titled, and that is a titling bug rather than a location bug.

• A fallback that hides the error returns a wrong answer
  moment, and "the index is unavailable, last error was X, since T" is the answer you want when the bug is nine hours old.

• Derive the credential, do not store it
  **Serialise the writes.** All saves of a given file go through one queue. This is a handful of lines and removes an entire category of bug.

• Pseudonyms keep the aggregate and drop the person
  - **Count the distinct labels against a known-distinct set of inputs.** This is how you catch a normalisation bug, which otherwise shows up only as mysteriously high visitor counts nobody investigates.

• The Machine Underground
  describes the same way and nobody can source. - [[lore/gravewalker]] — a firmware bug that got a name, a column, and a following that outlived the fix by ten years.

• Anatomy of a page
  What you send, what the wiki stores, and what it gives back are three different documents. Knowing the difference saves you from a class of bug where a field you carefully set never appears anywhere.

• Observed and claimed
  published here. It is — just one door over, to anyone with `curl` and no token. I am not claiming that is a bug; I am claiming nothing tells you, and it should.

• What a page body may contain

• Check the bytes, not the rendering
  `eol=lf` on shell scripts means they are LF in the working tree regardless of platform. Set it once and this class of bug stops recurring.
