The agent path was Linux-only because tokens had a keyring store only
there (every other OS hit NOT_YET, so `connect` and the bridge failed).
D-56's destination is one installation for macOS, Windows and Linux.
Both new stores sit behind the same Items trait as the Secret Service,
so INVARIANT 4 (one account, one item, locked is an error) is kept once
and tested once through the file keyring. Windows credentials have a
unique target name, so a probe stands in for a search.
New dependencies (ledger-host only, target-gated): apple-native-keyring-store
(feature keychain) and windows-native-keyring-store, the stores the
keyring-core 1 API we already use is published with. No ledger-core change.
The `portable` job builds and tests the workspace on macos-latest and
windows-latest. Windows is allowed to fail: the rest of the host is
Unix-only (inventory in docs/packaging.md). Not verified locally: no
macOS or Windows target is installed; CI is the evidence.
Also pins cargo-packager, cargo-packager-updater and cargo-generate-rpm
in mise.toml for the trial, and records that the trial is not yet run.

mise.toml: pin cargo-mutants 27.1.0 and cargo-fuzz 0.13.2 (the latest
published, and what is installed) instead of "latest", so mutation and
fuzz runs repeat (plan/served.md I-13, P0).
docs/mcp-interface.md: the spec had two Transports sections, and the
first claimed bearer-token auth on Streamable HTTP. There is none: the
server uses rmcp's default config, whose only guard is a Host check for
localhost, 127.0.0.1 and ::1, with no token and no Origin check. One
section now says so plainly and points to plan/served.md P2 for auth.
ledger-cli AGENTS.md template: "the journal is the evidence - read it,
don't guess" led an agent to cat the journal file instead of asking the
books. The template now says to trace a figure through books.get_entry,
books.search_entries, or books.export (journal or general_ledger), and a
new bullet says the books are reached only through the wanderbooks MCP
tools: never open, list or parse the books' files, not even to look; if
a tool can't answer, say so. The other lines that sent the agent to the
data dir go too: onboarding is triggered by an empty books.chart instead
of a missing journal.jsonl, the CPA paragraph drops the ledger-gui
--data-dir books-data command, and the backup note no longer names the
journal's path. Test agents_md_reaches_the_books_only_through_tools
pins this; agents_md_carries_the_contract no longer expects journal.jsonl.

Max-testing pass, ranks 4-6 and step 9 for ledger-core.
Fuzzing (rank 4): fuzz_op_sequence now drives balanced pairs, foreign
lines, periods, closes, and amounts from raw decimal bits, and asserts
the books stay valid (TB balances, posted entries validate, no draft in
a closed period); new fuzz_core_serde (every persisted core type
round-trips) and fuzz_store_open (a corrupt journal is an error, never a
panic); hangs count (-timeout=10). 54M executions; one crash:
- fuzz_journal_line: a number too big for an integer parsed as a float,
and its canonical form (which the hash chain covers) re-canonicalized
differently. The journal never holds floats (R-2), so the reader now
refuses them (JournalLine::parse, used by every journal reader);
regression a_journal_line_with_a_float_is_refused. Checked first: the
real books' journal has none. Rerun: 13.2M executions, clean.
Seeds in fuzz/seeds/ (synthetic, minimal); the grown corpora stay out of
git. `just fuzz <target> <seconds>`.
Miri (rank 4): the core's unit, bridge, and invariant tests under Miri
(our code has no unsafe; rust_decimal and chrono do): no undefined
behavior. `just miri`. A pinned nightly (nightly-2026-10-01, with miri)
is now in mise.toml.
Benchmarks (rank 6): criterion (new dev-dependency: the playbook's Rust
benchmark tool; none existed) in benches/books.rs; baselines in
docs/testing.md. The store's per-command rehearsal clone costs ~1 ms at
10k entries. No budget yet, so nothing gates on them. `just bench`.
CI: .github/workflows/check.yml runs `just check` on every push;
scheduled.yml runs proofs, the GnuCash oracle, fuzzing, and mutation
weekly. Tools come from mise.toml.
docs/testing.md: every layer, its oracle rank, command, runtime, and
gate; benchmark baselines; the ASSUMED invariants for the owner to reject;
the gap list with triggers. docs/oracle.md's fuzzing paragraph had
claimed persistent corpora that didn't exist; corrected.
Also: ledger-import now inherits the workspace lints (nightly cargo
warned).

Rust (with clippy and rustfmt), just, Node (for deploys), Kani, Lean,
cargo-mutants, and cargo-fuzz, so `mise install` is the whole bootstrap
and nothing gets installed by hand. Lean is 4.34.1, the newest release
past mise's minimum release age; verify/lean/lean-toolchain matches.
