restoreBackup becomes an orchestrator: the checks before the first delete
move to restore-preflight.ts, and the transaction runs the steps listed in
backup-domains.ts in dependency order, emptying the account first and then
rebuilding it domain by domain. The inline restores for measurements,
medications, mood, labs, illness, allergies, family history, workouts,
nutrient days, documents, the instance settings and the cleared
notification channels move into one module per domain, beside the
existing section modules. Cross-domain references travel through one
typed context instead of local variables.
The order of every write, the refusals and their audit rows, the skip
report, the cleared counts and the reported phases are unchanged; the
golden copies of the restored account still match. Guards that pinned
the restore by path now point at the domain files.
Add a ratchet mechanism (helpers/ratchet.ts): per-key counts against a JSON
baseline under src/__tests__/baselines/. A new key or a higher count fails;
a lower count fails until it is written back with
`RATCHET_WRITE=1 pnpm vitest run <guard>`, which only ever lowers numbers.
Raising one is a hand edit in a reviewed change. The baselines are
machine-written, so prettier leaves them alone.
helpers/source-metrics.ts measures the production tree through the
TypeScript compiler: the file list (dot directories included, tests and
generated code out), line counts, every function node with a stable
"outer > inner" name and its length, and the runtime import graph.
Guards and their baselines, measured on this tree:
- source-size-ratchet: 129 files over 800 lines and 415 functions over 200
lines (catalog and data files exempt, each named with its reason; slack
25 and 10 lines before a shrink must be written back).
- test-realism-ratchet: 321 route tests mocking @/lib/db wholesale, 138
stubbing @/lib/api-handler, 6014 `as never` casts in 570 test files, and
400 test files that read a source file by path (reads through readSource
are not counted).
- version-stamp-ratchet: 10634 comment lines in 2985 files that open with a
release version; none may be added.
Proof each can fail: a planted 953-line file with a 253-line function failed
both size ratchets, and one line appended to app/page-client.tsx failed the
file ratchet (2326 → 2327); a planted route test with vi.mock("@/lib/db")
and one `as never` failed both of those ratchets; a planted comment
"// v1.45.0 — probe stamp" failed the stamp ratchet. Raising one as-never
baseline entry by 5 failed with the write-back message, and RATCHET_WRITE=1
restored the file byte for byte. All probes were removed again.
