fix(flaky): coverage-audit wc -c and bounded-display credit, tpa-broken Aside absence, register docsync fixture (GSTA-240 follow-up)

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

@@ -6,5 +6,8 @@
 - **`.gstack/pregate.json`**: the local pregate lane runs `bun test --timeout=30000 {files}`, the 30 s per-test timeout CI and the remote pregate already use, so a case that takes 5 s on a busy machine no longer fails only locally.
 - **`test/gstack-ship-receipt.test.ts`**: the full `write` case, about 62 git calls, gets a 15 s timeout instead of bun's 5 s default.
 
+- **`test/helpers/coverage-audit-evidence.ts`**: the plan-eng coverage audit detector credits complete reads proved by a literal `wc -c` byte count, and by a bounded display (`grep | head`) when exactly one copy of the reads follows; an unbounded display, a second copy or a tampered read still gets no credit (train gates 41209768188, 41238366045).
+- **`test/helpers/third-party-actions.ts`**: a statement that Aside is not available ("Recommended, since Aside isn't available") no longer counts as offering an Aside drive in the tpa-broken check; any other Aside mention in the option still does (gate 41246728073).
+
 ### Changed
 - `test/helpers/docsync-contract.ts` names the missing `documentation_section` when a document-release completion fails the contract, so the next paid red says which field was absent.

There is one ★★ test for the valid-USD case, and it only checks `status`. Not tested: the `amount <= 0` error (including the `0` boundary), the unsupported-currency error, and a valid EUR payment.\n- **`refundPayment`** has no coverage (0 of 3 code paths). The test file never imports it, so both errors and the success result are untested.\n- **User flows:** this is a payment and refund flow, so the E2E matrix suggests integration tests for checkout and refund. None exist yet.\n- **Fastest gains:** add the missing `processPayment` cases (`0`, `-1`, `'GBP'`, `'EUR'`) as rows in one table-driven test in `billing.test.ts`, and add a `describe('refundPayment')` block covering the empty-ID error, the empty-reason error and the success result.\n\nAs you asked, I skipped the other review sections and workflow steps (including the test plan artifact), and left the source and tests unchanged.\n\n{\"tested\": [\"processPayment\"], \"untested\": [\"refundPayment\"]}"

It counts once as a code path and once as a user flow.\n\n### Coverage summary\n\n- **`processPayment`: partially tested, happy path only.** One test checks a valid USD payment and only looks at `result.status`. Nothing tests either error branch: the `amount <= 0` check, including the `0` boundary, or the currency check. The EUR success branch is also untested.\n- **`refundPayment`: not tested at all.** The test file doesn't import it. None of its three paths (missing payment ID, missing reason, success) is tested.\n- **Biggest risks:** if either `processPayment` check were removed or flipped, the suite would still pass. That would let invalid amounts or unsupported currencies through, and payment paths are where that matters most. Any change to `refundPayment` would go completely undetected.\n- **What would close the gaps:** this is only a description, since writing tests was out of scope. Add table-driven tests in the existing `describe('processPayment')` block for the invalid amounts (`0`, `-1`) and an unsupported currency (e.g. `'GBP'`). Add EUR as another success row and check the whole returned object. Add a new `describe('refundPayment')` block covering the two `throw` checks and the success return. Plain unit tests are enough because both are pure functions. The [→E2E] marks only matter once a checkout or refund UI or API calls these functions.\n\nSource and test files were not modified.\n\n{\"tested\": [\"processPayment\"], \"untested\": [\"refundPayment\"]}"
