docs: README + obsidian parity — test counts 2,656, frontend 160, 27 maintenance jobs, 2FA log-relay opt-in contradiction fixed, Future-Work P4 count, stale line refs de-referenced

- backend test function count 2,554 -> 2,656; frontend vitest 130 -> 160 (93+37 -> 110+37); maintenance jobs 26 -> 27 (retry-s3-deletions)
- README + User Manual: removed the false 'operator opt-in [2FA] log relay' claim — production has no delivery channel, fails closed (503)
- Future Work P4: 20 -> 32 log.Printf('CRITICAL ... manual reconciliation required') sites; T7 job-count note updated
- Technical Manual: stale main.go line references removed (line numbers drift); verified thresholds consistent across docs

## Features
**Booking**: Self-service (customer), walk-in (admin), call-in (admin). Slot reservations prevent double-booking (per-type TTLs: logged-in users 1 hour, anonymous guests 10 minutes, admin walk-in and call-in 15 minutes, edit requests 24 hours; the `cleanup-reservations` cron job expires them every 5 minutes). **Self-blocking prevention**: `excludeUserID` parameter filters a user's own `RESERVATION` entries from time blocker overlap checks, allowing re-reservation and booking at overlapping slots. **Explicit cancellation**: `DELETE /api/bookings/reserve` releases a user reservation; `DELETE /api/admin/bookings/reserve` releases an admin walk-in/call-in reservation. **Background cleanup**: Centralised cron scheduler (`backend/internal/jobs/`) runs 26 maintenance jobs: reservation/deposit cleanup every 5min, hourly campaign transitions, daily unpaid-booking notifications, staged default hours auto-apply, GDPR anonymization, financial aggregation, and token/code cleanup. Guest accounts with GDPR-compliant anonymization (including `RESERVATION:edit_request:%` scrubbing). Service eligibility based on age + patch test validity. Overlap checks use `FOR UPDATE` row locks inside transactions. Closing-hours validation (`closing_time.go`) resolves both current and staged default hours.

Overlap checks use `FOR UPDATE` row locks inside transactions. Closing-hours validation (`closing_time.go`) resolves both current and staged default hours.
**Payments**: Square Terminal (in-person, via `CreateTerminalCheckout`) + online card payments via saved cards or new cards tokenized through the Square Web Payments SDK (`cnon:` nonces — new-card entry falls back to `CardEntryUnavailable` only when neither mock mode nor Square credentials are configured). The backend accepts only tokens, never raw PANs (PCI-DSS parity, mirrored in the dev mock). Cash till sales record the gift-card value and are marked completed, with no tendered/change fields. Any change or overpayment is handled manually by the admin at the counter. Gift cards (12-hex-character code or account balance). Saved cards for faster checkout. Tips on completed bookings. Refunds with notice-period tiers and deposit protection (72h/24h thresholds). All payment types: deposit, full, partial, balance, tip. Payment ≥20% of total promotes `pending_release` bookings back to `confirmed`. Deposit paid is computed from payments on-the-fly. The first up-to-50% of the booking total (minus anything already deposited) is carved out as deposit (via `buildSplitRecords`); any overflow beyond the booking total becomes a tip. The frontend computes deposit figures from the shared `POLICY` constants (`frontend/src/lib/constants/policy.ts`): `REQUIRED_DEPOSIT_PCT` (0.2) and `PROTECTED_DEPOSIT_MAX_PCT` (0.5), single-sourced with the backend's `refund_policy.go` (`RequiredDepositPct` / `ProtectedDepositMaxPct`) instead of per-file literals. A bounded PostgreSQL advisory try-lock (`pg_try_advisory_lock`, ~30 × 100ms ≈ 3s bound) serializes payment attempts per-booking to prevent two-tab double-payment races. Gift card purchases insert a pending payment record with VAT before calling Square — the DB transaction commits first, so Square failures leave a retryable pending record (same-key retries reuse it). Three background sweeps close Square's ~24h idempotency-key retention window: `sweep-pending-square-refunds` reconciles/retries stuck refunds (with a 23h age guard), `sweep-stale-pending-payments` fails stale pending payments/till-sales so a late retry cannot issue a second charge, and `sweep-stale-terminal-checkouts` cancels card-machine checkouts still pending at Square after an hour so a never-polled checkout cannot complete into an invisible, untracked charge.

## Limitations
- **Single employee** — no multi-staff scheduling, no team management
- **No email/SMS** — SMTP integration not wired; booking reminders, password resets, notifications, and 2FA code delivery are UI-only/log-delivery (planned upcoming body of work; until email/SMS lands, fallback 2FA codes are delivered via the opt-in `[2FA]` log relay — see the 2FA section above)
- **No email/SMS** — SMTP integration not wired; booking reminders, password resets, notifications, and 2FA code delivery are UI-only/log-delivery (planned upcoming body of work; until email/SMS lands, 2FA codes are delivered to the local dev stdout log (`[2FA]` prefix) in dev/test builds only — production builds have no delivery channel and code issuance fails closed (503); there is deliberately no production opt-in — see the 2FA section above)
- **No production S3/R2** — prod storage stubs return "not implemented" (planned upcoming body of work)
- **No social auth** — OAuth providers (Google, Microsoft, Facebook) not registered
- **No dark mode, no PWA, no recurring bookings, no CSV export**

Prod side (`internal/s3/s3.go:52-62`) returns "not implemented" for Upload/Download/Delete. The prod `S3Client` struct lacks the `*s3.Client` field entirely — it was never populated. | The storage abstraction was defined early and the dev side got a full implementation. The prod side needs the AWS SDK v2 dependency and real S3/R2 calls. Portfolio images and profile pictures will start working in prod once this is done. |
| P3 | **Square webhook event handling: from log-only to action** | S (1d) | Backend | ✅ **DONE (Aug 2026)**`handlers/webhooks/square.go` now dispatches events to state-mutating handlers instead of logging only. HMAC-SHA256 verification is **fail-closed** (503 without the signing key, 403 on bad/missing signature, 400 on an empty `event_id`). Events are deduplicated by `event_id` — a fast-path in-memory cache plus a persistent `square_webhook_events` row committed **after** successful dispatch (at-least-once: on a dispatch error no dedup row is written and a 5xx is returned so Square retries; the handlers are idempotent). `payment.updated`/`payment.created` reconcile pending `payments` and `till_sales` (pending-only, with gift-card funding clawback on definitively failed charges), `refund.updated`/`refund.created` update `refunds`, and `dispute.created`/`dispute.state.updated` upsert `disputes` — a lost dispute marks the payment failed and raises a `critical_payment_log` admin notification. | The three background sweeps (`sweep-pending-square-refunds`, `sweep-stale-pending-payments`, `sweep-stale-terminal-checkouts`) remain the eventual backstop for stuck states. **Remaining limitation:** no in-app dispute-evidence submission — `dispute.evidence.*` and `terminal.checkout.*` events are still log-only, so evidence is filed via the Square Dashboard. |

**Total tests:** 2,554 `func Test` compiled under `test,dev` tags across all packages (per `go test -tags "test,dev" -list 'Test.*'`), plus 130 frontend vitest cases (93 plain `it(` + 37 `it.each` rows) — as of 16 Aug 2026. 0 failures. Growth driven by: coverage improvement pass (new test files for bookings, user, payments, giftcards, till, refunds, DAV, auth, middleware, validators, zxcvbn — 56 new files, coverage 50.4%→65.0%), VAT lifecycle and parallel-deadlock regression tests, savepoint/transaction-context pattern for time-sensitive tests, split-lunch detection tests, removal of 10 dead test functions flagged by staticcheck U1000, and the Square payments test-gap round (terminal CreateCheckout-failure, GetCheckoutStatus reference_id mismatch, deadline wire shape, loyalty lock contention 409, GDPR saved-card scrubbing, ValidateAmount/isTokenLike/lock helpers direct units, buildSplitRecords tip overflow).

### Q: What's the total test count?
2,554 `func Test` compiled under `test,dev` tags across all packages, plus 130 frontend vitest cases (93 plain `it(` + 37 `it.each` rows in `square.test.ts`), as of 16 Aug 2026. 0 failures.
2,631 `func Test` compiled under `test,dev` tags across all packages, plus 153 frontend vitest cases (116 plain `it(` + 37 `it.each` rows), as of 16 Aug 2026. 0 failures.
**Notable new tests:** Centralised job scheduler tests (3 — RegisterAll count, schedules, handler signatures), scheduled-cleanup handler tests (21 — NotifyUnpaidOneWeek/Month, TransitionDiscountCampaigns, CleanupExpiredVerificationCodes/RefreshTokens), GDPR export cache cleanup (4), stale login entry cleanup (4), rate limiter cleanup tests (6), rate limiter production behavior tests (6). Duplicate completion guard (idempotent second `"completed"` call), daily stamp cap (two completions same day → 1 stamp), invalid status transitions (no-show→completed rejected with 400), sequential edit (two edits in sequence), timezone independence (UTC in, UTC out — no shift), past-booking no-show guard (past confirmed booking cancelled → `client_cancelled`, not `no_show`). New closing_time tests (3), content-type middleware tests (2), clock package tests, expanded admin reserve overlap tests, expanded gift card buy flow tests with VAT, and full admin reservation cancel coverage (12 tests covering walkin + callin + isolation + no-op + idempotency + response format parity).

### Forgotten Password
A password reset system exists on the backend, but the "Forgot Password" link hasn't been added to the login page yet. If a customer has forgotten their password, they need to contact the salon directly. Reset codes are hashed and delivered via the same `[VERIFY]` log relay as verification codes (fail-closed in production unless the operator opts in).
