place_bet and request_withdrawal released everything on any exception from the
broadcast, including the 15s timeout and a connection dropped after the write. The
tx may have propagated: a bet's sats landed in the pool with no participant, a
withdrawal left while its row said failed and its coins were spendable again.
- client: ElectrumRpcError (subclass of ElectrumError) is raised only for a reply
carrying a JSON-RPC `error`; timeouts, drops and write errors stay plain
ElectrumError.
- tx/outcome.py:broadcast_with_verdict sorts a broadcast into accepted / refused /
uncertain. A refusal is verified first: ElectrumListener.transaction_known asks
blockchain.transaction.get of the active server and every other one (10s each) —
any server returning the tx means accepted; the active server plus
MIN_QUORUM_RESPONSES others all denying it means refused (ALLOW_NO_QUORUM keeps
the reduced rule); too few answers is uncertain. "already known" wording is only a
shortcut that skips the check. With no network to ask, a refusal is uncertain.
- place_bet / request_withdrawal / _trigger_payout use it: only a verified refusal
releases; uncertain leaves the rows building for the reconciler, publishes SSE and
POST /bets and POST /withdrawals answer 202 with status building; "already known"
promotes a payout (payout_sent) like any accepted broadcast.
- An accepted transaction is fanned out to every other server
(ElectrumListener.fan_out_transaction, best effort, off the caller's path). The RBF
replacement in bump_fee is left for B-77, which rewrites that function.
Tests changed because the spec changed: the existing "refused broadcast" tests raised
a bare RuntimeError (now an uncertain outcome) and are made explicit refusals
(rpc_error) with a network that denies the tx; direct route calls pass a Response;
FakePayoutListener gains the network surface.

- Add docs/README.md as the index of all documentation.
- Split the 52 DEC entries of decisioni-e-limiti.md into docs/adr/ADR-NN
files (same numbers), add ADR-53 (audit log), TEMPLATE.md and an ADR index
with a feature -> ADR table.
- Rename decisioni-e-limiti.md to limiti-noti.md (LIM only) and rewrite all
DEC-nn references as links to the ADRs.
- Document the docs-first / SSOT / ADR rules in processo-di-modifica.md and
map the docs in CLAUDE.md and README.md.

Finishes what 88221b0 started: sicurezza.md, audit-log.md and storico-bug.md
now describe the target behaviour too, the operator guides are corrected
against today's code, and api.md gains the missing /health/ready and
/admin/electrum sections plus every new error code in its catalog.
Harmonised names and owners across documents (the `resurrected_tx` pause
reason, the reconciler as the one that watches failed rows, the full
`winner_drawn` payload, a reason for an unanswered pre-payout pool check,
one corroboration-failure row per hash instead of one per tick).
Adds B-98 (coin selection stops at the first covering UTXO and refuses a
payable bet), tightens RND-40 to check both 1 and 400 participants and to
guard PUT /admin/config, and gives a stalled `closing` round a signal
(TX-29, closing_stalled).
Records three decisions confirmed on 2026-09-29: the draw's server_seed is
stored Fernet-encrypted until revealed (SEC-56, DAT-64), the chosen abuse
and key-check thresholds (SEC-49, SEC-54, SEC-55), and a broadcast
rejection is verified against every server before any coin is released,
so matching "already known" text is a shortcut, not a safety condition
(TX-04).
Spec only; no code changed.

The two Mermaid diagrams under flowchart/ described the intended flow but
had drifted from the code and carried no link back to it. docs/ now holds
the specification instead: 15 Italian documents (flows, architecture, data
model, API, security, audit log, operations, decisions and limits, bug
history) with 472 numbered requirements, each pointing at the function
that implements it and the test that covers it. docs/processo-di-modifica.md
defines the ID convention and the spec -> code -> test change workflow, and
CLAUDE.md now names docs/ as authoritative.
Writing the spec from the code also corrected stale claims in CLAUDE.md
(B-41's get_history check, BUGS.md still tracking B-71/B-72, Cache-Control
scope, the error contract's bare-string exceptions) and in the operator
guides (payouts do retry, only `drawing` fails to resume, rounds do not
open without fee_address). The B-70 doc test now pins the prose in
docs/scommesse-e-prelievi.md instead of the deleted diagram.
