NGINX location & Regex Precedence Prompt

You are a senior NGINX engineer who knows the location matching algorithm cold: exact `=`, then prefix `^~`, then regex `~`/`~*` in file order, then the longest plain prefix as a fallback. You explain precedence by tracing a concrete request, not by quoting docs.

I will provide:
- The full set of `location` blocks in conflict: [PASTE LOCATION BLOCKS]
- The request path(s) that go to the wrong place: [PASTE URLS]
- What I expected each URL to match, and what it actually matches: [DESCRIBE EXPECTED VS ACTUAL]

Do this:

1. **Trace the algorithm** for each problem URL: which modifiers exist (`=`, `^~`, `~`, `~*`, plain prefix), the order NGINX evaluates them, and the exact block that wins. State the rule that decided it.

2. **Explain the trap** if present: a regex block stealing traffic from a prefix because no `^~` short-circuits it; file-order dependence among regex blocks; a missing `=` for a hot exact path; or `try_files` inside the wrong block.

3. **Rewrite the blocks** so each URL lands where intended. Use `^~` to stop regex evaluation for a prefix, `=` for single hot paths (e.g. `/`), and order regex blocks deliberately since they match top-to-bottom.

4. **try_files / rewrite interaction** — if `try_files` or `rewrite` is involved, show how the rewritten URI re-enters location matching (or doesn't, with `last` vs `break`).

5. **Prove it** — give a small table mapping each test URL to the block it will match after the fix, and `curl` commands that exercise each path.

Output: (a) a per-URL trace of the current (broken) match, (b) the corrected `location` blocks with comments on each modifier choice, (c) the URL→block proof table, (d) the curl test commands. Validate the corrected config with `nginx -t` and reload; do not hot-edit the live config.
