feat(#80): IMP-52 user_overrides.json persistence (u1~u10 backend + frontend + tests)

Browse Source 
4-axis MDX-stem keyed persistence so layout / zone_geometries / zone_sections / frames
survive across `/api/run` sessions. Auto-restore on MDX reopen; CLI > file precedence
on backend pipeline entry; 300ms-debounced PUT flushed before Generate.

u1 src/user_overrides_io.py — load/save/validate_key (MDX-stem regex), 4-axis schema,
  miss={}, corrupt warning+{}, atomic tmp+rename, foreign-key preserve.
u2 src/phase_z2_pipeline.py — post-argparse fallback fills only missing axes.
u3 Front/vite.config.ts — GET /api/user-overrides/:key (200 {} on miss, 400 traversal).
u4 Front/vite.config.ts — PUT /api/user-overrides/:key, 4-axis allowlist, partial merge.
u5 Front/client/src/services/userOverridesApi.ts — typed get/save + flushUserOverrides
  with 300ms debounce and mutated-axis partial payloads.
u6 Front/client/src/pages/Home.tsx + slidePlanUtils.ts — restore on MDX upload (non-frame
  axes immediately, frames remapped post-loadRun unit_id → region.id).
u7 Home.tsx — persist on 4 mutation handlers (section drop, layout select, zone resize,
  frame select); zone_sizes and Generate excluded.
u8 tests/test_user_overrides_io.py — round-trip, unknown-key passthrough, missing/corrupt,
  invalid keys (26 tests).
u9 tests/test_user_overrides_pipeline_fallback.py — per-axis fill, CLI-wins, no-file noop,
  corrupt warning+skip (16 tests).
u10 Home.tsx + user_overrides_write.test.ts — await flushUserOverrides() before runPipeline
  in handleGenerate try-block head; source-pattern regression assertions (20 → 22 tests).

Backend pytest 42/42 green. Frontend vitest 113/113 green (endpoint 42 / restore 21 /
service 28 / write 22). HEAD baseline ee97f4f; no spillover to phase_z2 templates /
families / frames / pipeline orchestration outside the IMP-52 surface.

// IMP-52 u5 — vitest coverage for the typed frontend client at
// `Front/client/src/services/userOverridesApi.ts`.
//
// Scope (Stage 2 unit u5 contract):
// 1) getUserOverrides:
// • 200 with object body → typed payload echoed.
// • 200 with array / primitive / non-JSON body → {} (graceful).
// • 4xx / 5xx → {}.
// • fetch reject (network) → {} (no throw to caller).
// 2) saveUserOverrides:
// • Single call: PUT fires after exactly 300 ms with the mutated-axis
// partial as body (NOT a full snapshot of UserOverrides).
// • Rapid coalescing: N calls in <300 ms window collapse to ONE PUT
// carrying the union of mutated axes.
// • Per-axis later-wins: later call's value replaces earlier pending
// value for the same axis; axes the user did not touch stay absent.
// • null sentinel: forwarded verbatim so u4 mergeUserOverrides can
// `delete` the axis on disk.
// • Per-key isolation: rapid edits to "03" do not delay flush of "04".
// • Promise resolves with the server-side merged document.
// • Promise rejects on 4xx/5xx and on fetch reject.
// 3) flushUserOverrides:
// • No arg → flushes all pending buckets immediately (no 300 ms wait).
// • Specific key → flushes only that bucket; other buckets stay
// pending.
// • No-op when no buckets are pending.
//
// All tests mock `fetch` and use `vi.useFakeTimers()` to make the 300 ms
// debounce deterministic — no real wall-clock waits.

// IMP-52 u10 — Frontend write-side regression coverage.
//
// Stage 2 unit u10 contract:
// 1) All 4 in-scope mutation handlers persist their axis.
// 2) zone_sizes is NOT persisted (handleLayoutResize stays in-memory).
// 3) Write-before-Generate ordering — flushUserOverrides forces pending
// PUTs to commit before the pipeline run begins.
// 4) Restore-on-reopen end-to-end — getUserOverrides → non-frame layering
// and post-loadRun frame remap compose into a single restored state.
//
// React Testing Library is NOT installed in this repo (devDependencies has
// vitest only). Home.tsx's mutation handlers live inside `useCallback`
// closures so they cannot be invoked from a test without mounting the
// component. We cover them with two complementary tactics:
// • Source-pattern grep on Home.tsx that pins the exact wiring shape per
// handler. A regression that drops or rewires a `saveUserOverrides`
// call fails here loudly.
// • End-to-end mocked-fetch tests on the `userOverridesApi` flow with the
// payload shapes that Home.tsx produces — proves the contract the
// handlers depend on still holds.
//
// File extension is `.ts` (no JSX). All tests run in vitest's default node
// environment; fetch is stubbed with vi.stubGlobal and timers are faked so
// the 300ms debounce in `saveUserOverrides` is deterministic.

"""IMP-52 (#80) u1 — user_overrides.json persistence layer (backend IO).
Persists the four CLI-wired override axes per MDX so a subsequent render
auto-restores user choices without re-clicking. Source of truth = MDX-keyed
file (stem of the MDX path), NOT ``data/runs/<run_id>/`` which mints a fresh
run_id per ``/api/run`` invocation.
Schema (4 axes; stable order):
{
"layout": <string|null>,
"zone_geometries": {<zone_id>: {"x": float, "y": float, "w": float, "h": float}},
"zone_sections": {<zone_id>: [<section_id>, ...]},
"frames": {<unit_id>: <template_id>}
}
``unit_id`` is the convention already used by ``--override-frame`` :
``"+".join(source_section_ids)`` (e.g., ``"03-1"`` or ``"03-1+03-2"``).
Behavior :
- ``load(key)`` — file missing or corrupt → ``{}`` (warning to stderr on corrupt).
- ``save(key, partial)`` — merges only the supplied axes onto the existing
file, preserving (a) unknown top-level keys (foreign-key preserve) and
(b) axes not present in the partial payload. Atomic write via tmp+rename.
- ``override_path(key, root=None)`` — resolves the persistence path under
``data/user_overrides/<key>.json``.
Guardrails (refs : ``user_overrides_io`` Stage 2 lock) :
- Deterministic code, no AI fallback.
- ``key`` validation rejects path traversal / separators / dot-prefix.
- ``save`` is a deep-shallow merge — per-axis dict mutation does not delete
prior keys unless caller passes ``None`` for that axis (explicit clear).

"""IMP-52 (#80) u9 — backend tests for the argparse persistence fallback.
Stage 2 u9 scope (per the Exit Report):
1. Per-axis fill — file value flows through when CLI omits the axis.
2. CLI-wins — CLI value beats file value on the same axis.
3. No-file noop — missing file → ``run_phase_z2_mvp1`` gets all-None.
4. Corrupt-file warn — invalid JSON / non-object → stderr warning + skip.
5. Invalid stem warn — ``Path(args.mdx_path).stem`` rejected by validator
→ warning + fallback skipped wholesale.
We exec the ``if __name__ == "__main__"`` block of
``src.phase_z2_pipeline`` directly inside the module's namespace, after
(a) monkeypatching ``src.user_overrides_io.DEFAULT_OVERRIDES_ROOT`` to a
tmp directory and (b) replacing ``run_phase_z2_mvp1`` with a recording
stub. This exercises the production fallback verbatim without the cost
of a real pipeline invocation.
