Stack: master ← #26 ← #27 ← #28 ← #29 ← #30 ← #55 ← #60. #20, #22, #57, #24 and #19 are merged.

• New guides: docs/guides/wallets.md (create, inspect, ledger, policies, delete) and docs/guides/webhooks.md (create with --output-file for the one-time secret, event names from the contract, test, stop/start, key rotation, deliveries). The docs index links both.
• Offline dry run of every documented change: a new integration test takes each docs example that passes --execute, swaps in --dry-run --json, and requires exit 0 and outcome: dry_run, with no request reaching the mock API. Placeholder IDs become a fixed UUID. Examples that read a --data file get stub bodies (payment.json, policies.json, test-delivery.json), and --data - gets the payment body on stdin. A new @FILE in the docs fails the test until it has a stub.
• No file created: the test lists the scratch directory before the loop and requires the same entries after it, so no --output-file, journal, or other file appears.
• Shared extractor: tests/support/examples.rs holds the docs example extractor, included by the parse test in src/cli.rs and by the new integration test.

The new test found a real docs bug while writing these guides: webhooks test needs a --data body (delivery_id and payload), so the guide shows it that way.

Payments, receive/send, prices, checkout, and payment reliability are already covered by payments.md, checkout.md, and the safety model, so this PR does not split or duplicate them.

--dry-run in this layer: #30 removes --dry-run further up the stack and rewrites these lines and this test to run without --execute instead. This layer is accurate for its own head.

Changes after review

• The --data examples run too, with stub bodies, so the development guide's claim that every documented change runs offline is now true. The minimum number of checked examples rose from 15 to 19.
• The no-file check covers every new entry, not only webhook.json.

Checks

On 4cfa07d:

• cargo fmt --check, cargo clippy --locked --all-targets -- -D warnings, cargo machete --with-metadata: pass.
• cargo test --locked: 98 unit and 86 integration tests pass. VOLTAGE_BLESS=1 cargo test --locked leaves the tree clean.
• python3 scripts/check-coverage.py: pass.
• CRAP (scripts/crap-report.sh): no function at or above 20. Highest is api::wait_for_payment at 19.24, unchanged from or lower than master (19.66).
• Skill review: voltage-pr-review and the voltage-backend-engineering Rust checklist, against the stack base. Findings are fixed in this commit.

Not run: the staging and live tutorials, which need credentials.

nothing blocking, just one suggestion, this is ready to go otherwise

A few small doc notes, none blocking. The robot checked the guides against the code and the contract: the event table, the wallets create flags, ndjson, and the one-time-secret refusal all match. CRAP on d1482ef: no function at or above 20, highest api::wait_for_payment at 19.24. All 98 unit and 86 integration tests pass.

The merge-base changed after approval.
