Four new JSON routes mirror the Go /api/* handlers so the M5.4 parity
tool can diff them: /api/version, /api/adults, /api/juniors,
/api/payments. A small _unwrap_view_model_for_api() helper in app.py
expands the three pre-serialised JSON strings in the view-model dicts
and renames month_labels_json → month_labels and
raw_payments_json → raw_payments to match the Go wire contract.
Tests in test_app.py assert top-level key sets match the Go API schema
and that member_data, month_labels, raw_payments are objects not strings.

Add internal/web/api package with Go structs for every /api/X route:
AdultsResponse, JuniorsResponse, PaymentsResponse, VersionResponse.
All fields carry explicit json: tags matching the Python view-model keys.
Key design choices:
- member_data / month_labels / raw_payments are nested objects (not
the pre-serialised JSON strings used in Jinja templates)
- Expected{Value int; Unknown bool} with custom MarshalJSON emits int
or the string "?" for junior single-attendance months
- RawTransaction covers the full 11-column payments sheet row
schemagen_test.go reflects all four response types via
github.com/invopop/jsonschema and golden-compares against committed
schemas in tests/fixtures/api-schema/. The JSONSchema() method on
Expected lives in the test file so the prod binary has no jsonschema
dependency.
Closes M5.1 in docs/plans/2026-05-03-2349-go-backend-rewrite-progress.md.

Accidentally removed when moving group_payments_by_person to views.py;
re.match in qr_code caused a 500 on every QR request.

Pull 350+ lines of inline per-row computation out of adults_view,
juniors_view, and payments into three pure builder functions with no
Flask globals or IO dependencies. Route handlers now contain only
cache/IO calls and a single render_template. No behaviour change —
all 27 tests pass.
Also moves get_month_labels, group_payments_by_person, and
adapt_junior_members out of app.py. Prep for /api/* shadow endpoints
(M5 Go parity).

Fio's transparent account page now serves dates as DD.MM.YY (e.g.
07.05.26) rather than the previously expected 4-digit-year format.
Extends parseCzechDate to try all eight layout variants: padded and
non-padded, dot and slash separators, 4-digit and 2-digit years.
Go maps 2-digit year 00-68 → 2000-2068, so 26 → 2026.

Wraps `LOG_LEVEL=DEBUG ./bin/fuj sync -dry-run -print-fio-table -days N`
behind a single make target. Default DAYS=30, override with
`make go-sync-debug DAYS=90`. Builds the Go binary first via go-build.

Wires slog.SetDefault to honour LOG_LEVEL in all CLI commands and adds
debug logs on the Fio fetch path so a silent "fetched 0 transaction(s)"
can be diagnosed without code changes:
- fio.New: which client variant (api/transparent) was selected
- apiClient: GET URL (token redacted as ****), HTTP status, body bytes,
parsed transaction count
- transparentClient: GET URL, HTTP status, body bytes, plus parser
stats (raw rows from second table, kept, dropped_bad_date,
dropped_nonpositive_amount)
Also suppresses the --print-fio-table block when zero transactions were
fetched, so the bare header no longer prints under that condition.

Prints an aligned tabwriter table of every Fio transaction in the
look-back window, with a STATUS column showing NEW (would be appended)
or DUP (already in sheet). Only fires when --dry-run is also set, so
it can't affect real syncs. Refactors Sync ID computation into a single
pre-pass shared by both the table printer and the row builder.

extractSecondTableRows tracked a boolean inTarget flag and exited on
the first </table> token while inside the target. Any nested <table>
(e.g. pagination markup in the real Fio page) would cause an early
return before reading any data rows, explaining the 0-transaction report.
Fixed by tracking targetDepth instead: depth increments on every <table>
inside the target and we only return when it reaches 0 again.
parseCzechDate also only tried zero-padded layouts ("02.01.2006").
The real Fio transparent page emits non-padded dates ("7.5.2026");
added "2.1.2006" and "2/1/2006" as the preferred layouts.
Also adds a dry-run diagnostic line ("fetched N transaction(s) from Fio")
so the fetch vs dedup split is visible without reading logs.

When token is empty, New falls back to transparentClient with the
caller-supplied hc. main.go passes nil, so the first Do() call panicked.
Default to http.DefaultClient when hc is nil.

Mirror fuj infer's read-only mode: SyncOpts.DryRun skips WriteHeader,
AppendValues, and SortByDateColumn, printing one "Dry run: would …"
line per planned operation instead. ID-dedup still runs so the output
reflects exactly what the next real sync would write.

Closes M3.1–M3.6. Parity safety net proving Go output matches Python
for every ported pure-domain function (M2.1–M2.9) and reconcile (M2.10).
Capture pipeline:
- scripts/capture_fixtures.py: calls each Python function with seeded
inputs, emits JSON fixtures to stdout (never writes files directly).
- scripts/scrub_fixtures.py: deterministic PII scrubber — SHA-256
pseudonyms for member names, digit-preserving hashes for VS/account/
bank_id, name-sweep in message text. Idempotent; no salt.
- scripts/_fixture_seeds.py: handcrafted seeds for all 11 functions;
synthetic names throughout (no real roster members).
- scripts/capture_all_fixtures.sh: convenience wrapper for full corpus
regeneration outside of make.
Fixture corpus (98 files, all PII-free):
- go/tests/fixtures/pure/<func>/<case>.json — 10 function directories.
- go/tests/fixtures/reconcile/<NN>_<case>.json — 10 branch-coverage
cases: greedy, overpayment credit, proportional remainder, even-split,
out-of-window, exception override, other: purpose, junior ?, multi-
person+month fan-out, unmatched.
Go parity tests (//go:build parity):
- go/tests/parity/parityio.go: generic LoadDir/RunAll helpers + typed
In/Out struct pairs for all 10 pure functions; Envelope decoder for
int/float/none disambiguation.
- 10 pure-function test packages + bespoke reconcile test with per-cell
float tolerance (math.Abs <= 0.01 for `paid` values).
Makefile: go-parity, go-test-all, capture-fixtures targets.
go/tests/fixtures/README.md: refresh workflow + PII audit guide.
Gate: make go-test green, make go-parity green (11/11 packages),
make go-lint clean (parity tag), make go-build clean.

Add internal/services/membership package: AttendanceLoader,
TransactionLoader, ExceptionLoader interfaces + NewStubSources stub
(returns ErrIOPending until M4 lands real Sheets loaders).
FeesReport and ReconcileReport orchestrate domain/fees + domain/reconcile
and write fixed-width text reports matching Python calculate_fees.py and
match_payments.py print_report output. 13 unit tests cover all formatter
branches and orchestration wiring via fake loaders.
cmd/fuj/main.go: fees and reconcile subcommands now dispatch; sync/infer
retain the [M4] placeholder.

infer_payments was building member_names from get_members_with_fees()
(adults sheet only). Junior-only members were invisible to the matcher,
so a payment message containing an exact junior name would produce a
fuzzy review match against a different adult sharing the same first name.
Fix: union the adult and junior rosters (deduped via canonical_member_key)
so all members are candidates. The existing exact-name short-circuit in
match_members then handles precedence correctly.
Two regression tests added for the Jáchym Kubík / Jáchym Hrušák case.

New go/internal/domain/matching package porting three helpers from
scripts/match_payments.py:
- BuildNameVariants: normalized ASCII variants from a member name (nickname
in parens, last/first split, len<3 filtered); variants[0] is always the
full base name — MatchMembers relies on this invariant.
- MatchMembers: auto/review confidence matching with an exact-name
short-circuit pass that prevents nickname substrings (tov) from firing
inside longer surnames (ottova); common-surname filter for review tier.
- FormatDate: nil/empty/""/serial int/float64 (since 1899-12-30, fractional
days supported)/YYYY-MM-DD passthrough/garbage → never errors.
- InferTransactionDetails: composes BuildNameVariants+MatchMembers+
ParseMonthReferences; falls back to sender-only member match and
date-derived month when text carries no signal.
21 table-driven tests; all expected values verified against live Python
on 2026-05-06. go-build, go-test, go-lint all clean.

SHA-256 dedup hash from sync_fio_to_sheets.py generate_sync_id.
Key subtlety: Python str(float) emits "500.0" for whole-valued floats
and switches to scientific notation at |f|>=1e16 or |f|<1e-4 —
replicated via formatAmount using 'f'/'e' format selection.

Port scripts/infer_payments.py parse_czk_amount to Go as
internal/domain/money.ParseCZK. Preserves the Czech-locale heuristic
(comma = decimal sep; 2+ dots = thousand seps; single dot = decimal)
and returns (float64, error) so callers can opt into Python's
silent-zero contract via v, _ := money.ParseCZK(s).
All expected values verified against live Python on 2026-05-06.

Ports calculate_fee and calculate_junior_fee from scripts/attendance.py
into a new go/internal/domain/fees package. Introduces the Expected type
(Value int, Unknown bool) for the junior "?" sentinel, keeping the Go
API strictly typed instead of mirroring Python's str|int return.
All 20 table-driven tests pass with -race; golangci-lint clean.

ADULT_FEE_DEFAULT is 700 CZK, not 750. The 750 appears in
ADULT_FEE_MONTHLY_RATE for most current months but is not the fallback.
Rephrase the member-tiers bullet to point at the dict rather than a
number that drifts each season; update the fee-calc bullet to match
the junior line's style (default 700 vs default 500).

Three-pass regex parser matching python/czech_utils.py parse_month_references:
1. Numeric slash notation — "11+12/2025", "01/26"; 2-digit year → +2000
2. Dot notation — "12.2025" (4-digit year only)
3. Czech month names — range walk (listopad-leden wrap logic) then
standalone with m≥10 → defaultYear-1 heuristic; longest-match
alternation (sorted desc by name length) handles cervenec vs cerven
35 table-driven tests, all expected outputs verified against live Python
