Typo: "occured" should be "occurred" in transactions result-codes doc

[kaankacar]

The Horizon transactions result-codes reference has a misspelling: docs/data/apis/horizon/api-reference/errors/result-codes/transactions.mdx contains "occured" which should be "occurred". Small, single-file wording fix.

Checked: docs/data/apis/horizon/api-reference/errors/result-codes/transactions.mdx on main; searched open/closed issues and PRs for related items.

Evidence:

• docs/data/apis/horizon/api-reference/errors/result-codes/transactions.mdx:48 — - an unknown error occured — typo confirmed as described, not yet fixed.
• No duplicate issues or PRs found (gh search issues/gh pr list for "occured" / this file returned only this issue).

Conclusion: confirmed-valid. Labeled documentation + P2 (wording-only fix, no user-breaking impact, so no P1).

Auto-fix judgment: This would qualify as a safe auto-fix candidate — single word, single file, unambiguous correction — but this repo's label set has no triage:autofix-candidate (only triage:close-candidate, triage:approve-close, triage:needs-info, triage:digest, auto-merge-candidate, P1, P2 exist per setup-labels.sh/policy). Flagging here instead: a maintainer or agent with write access can apply s/occured/occurred/ at line 48 directly.

@copilot can you create a branch?

Re-checked (follow-up pass): docs/data/apis/horizon/api-reference/errors/result-codes/transactions.mdx on main; re-ran dedupe search across open/closed issues and open PRs.

Evidence:

• docs/data/apis/horizon/api-reference/errors/result-codes/transactions.mdx:48 — - an unknown error occured — typo still present, not yet fixed on main.
• No duplicate issues (open or closed) and no open PR touches this file or string "occured".
• The @copilot can you create a branch? request above is a request to a different agent (Copilot); it hasn't produced a PR yet, so nothing here is resolved by it.

Conclusion: confirmed-valid, unchanged. Labels: documentation + P2 retained.

Auto-fix judgment: triage:autofix-candidate label now exists in this repo's label set (it didn't at the time of my last comment) — applying it. This is a single-word, single-file, unambiguous wording correction (occured → occurred) with no ambiguity in outcome, no multi-file impact, and nothing security-relevant, so it meets all the auto-fix criteria.

Re-verified (follow-up pass): No change since the last two passes.

Evidence:

• docs/data/apis/horizon/api-reference/errors/result-codes/transactions.mdx:48 — - an unknown error occured — typo still present on main.
• Dedupe: no duplicate open/closed issues (gh search issues "occured" → only Typo: "occured" should be "occurred" in transactions result-codes doc #29) and no open PR touches this file or string (checked all 11 open PRs).
• The @copilot can you create a branch? request in this thread has not produced a PR yet.

Conclusion: confirmed-valid, unchanged. Existing labels (documentation, P2, triage:autofix-candidate) remain correct — single-word, single-file, unambiguous fix, no further action needed from this pass.
