`AuthorizationController::callback` sat at cyclomatic complexity **16**
against a
repo threshold of **10**, so the `crap` check went red on every PR that
touched
the file regardless of what the diff did — most recently #782, where the
change
was a single array entry.
This is a **pure refactor: no behaviour change.** No test was modified,
and
`.crap-ignore.json` stays empty — the complexity is actually gone, not
exempted.
## What moved
`callback` is a fixed-order OAuth funnel, so the order is preserved
exactly and
each phase became a named private helper:
| New helper | What it holds |
| --- | --- |
| `handleAuthorizationError()` | the `error` query-param branch,
including the pending-connection cleanup |
| `failureRedirect()` | the two `isOnboarded()` ternaries picking the
failure destination |
| `createProviderSession()` | the `createSession` try/catch and its
state-token cleanup |
| `completeReconnect()` | the reconnect terminal branch |
| `completeFirstConnection()` | the first-time-connection terminal
branch |
What is left in `callback` is a linear chain of guards ending in one of
two named
completions. `failureRedirect()` also collapses four repeated
`(route, params, 'error', message)` argument lists into one call each.
## Complexity
| Method | Before | After |
| --- | --- | --- |
| `callback` | 16 | **8** |
| `handleAuthorizationError` | — | 5 |
| `createProviderSession` | — | 3 |
| `completeFirstConnection` | — | 2 |
| `failureRedirect` | — | 2 |
| `completeReconnect` | — | 1 |
8 rather than exactly 10 is deliberate: at 10 the next single added
branch puts
the file straight back over the line, which is the problem this PR
exists to fix.
## One deliberate detail
`createProviderSession()` returns `null` on failure, and the caller
checks
`=== null` rather than falsiness. A session payload that is merely empty
therefore keeps failing downstream exactly as it does today, instead of
becoming an error redirect it never was.
## Verification
- `php artisan crap --base=origin/main --no-coverage` — pass, nothing
above 10
- `php artisan test tests/Feature/OpenBanking` — 341 passed, 1150
assertions (identical to the run on `origin/main` before the change)
- `vendor/bin/pint --test` — pass
- `bun run dry` — pass, and clone counts are byte-identical to
`origin/main` (176 PHP clones, 2163 duplicated lines before and after),
so the split introduced no duplication
- `vendor/bin/phpstan` on the changed file — 0 errors
`findPendingConnectionForSession` in the same class is at 11 and
untouched here;
it is pre-existing and out of scope for this PR.
