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.

Fourth full audit, run against the docs/ specification instead of the code
alone, found logical flaws rooted in PLM's small hashrate (~22 TH/s): a
minable draw, no distinction between "never broadcast" and "unknown if
broadcast", an Electrum client that degrades as the pool address's history
grows, and 1-confirmation deposits on a chain where a reorg is rentable.
The spec now describes the target behaviour for every finding, marked
*Stato:* da implementare (B-nn) with an *Oggi:* line for what the code does
now; docs/piano-correzioni.md records the design decisions and the
implementation order. No code changed — this is spec-only, per B-nn
convention when a bug reveals the spec itself was incomplete.
Also documents, as an accepted-but-open risk (LIM-24), that the optional
jackpot cap (max_round_pool_sats) isn't tied to the cost of a 51% attack —
deferred, not decided.

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.
