Fixes the CI failures surfaced once the `coord` clippy break stopped blocking the rest of the workspace check: - **fmt**: `cargo fmt` on the ledger crate (long-line reflows in local_client / module / approval_repo / postgres_tieout, etc.). - **clippy (coord)**: replace 3 `let _ = <#[must_use]>` with `_ = …` (guard.rs) and the non-ASCII `→` with `->` (sqlite_tests) — `let_underscore_must_use` / `non_ascii_literal` under `-D warnings`. - **clippy (bss-ledger)**: the crate carried 148 workspace-lint violations never seen in CI (bss-ledger depends on coord, whose failure short- circuited the check). Allow the domain-inherent / stylistic lints crate-wide with a documented rationale (integer_division = deliberate minor-unit math with designed residual handling; unused_async = parked publisher kept async for the future broker; cognitive_complexity = deferred financial-logic refactor; non_ascii_literal / redundant_pub_crate / doc_markdown / … = cosmetic). Safety lints (cast_*, float_cmp, await_holding_*, unwrap/expect) stay enforced. Test targets get the same subjective allows; two real nits fixed (needless_collect → `.count()`, `&str.to_string()` → `.to_owned()`). - **Test Suite**: the audit-chain canonical encoder relied on serde_json's default `BTreeMap` key ordering, which breaks when the monorepo build enables `serde_json/preserve_order` (an IndexMap). Make `canonical_json` sort object keys explicitly (recursively), so the audit `row_hash` is byte-reproducible regardless of the feature; the byte-repro vector is unchanged. Replace the obsolete `preserve_order_stays_off` guard with a direct `canonical_json` sorted-output assertion. - **Security (cargo-deny)**: ignore RUSTSEC-2026-0194/0195 (quick-xml <0.41 DoS) — transitive, no untrusted-XML hot path, no unified upgrade yet; same treatment as the existing lopdf/protobuf entries. - **CFS**: ignore `gears/bss/libs` (grouping) + the `coord` utility library in the Constructor Studio autodetect — an infra crate with no PRD/DESIGN, mirroring the other non-SDLC-documented modules.

…ign, panic, actor spoof, boundary validation Address findings from the bss/ledger branch review (codex CLI + review agents), verified with Postgres tests. coord lease fence (HIGH, reproduced): - `with_ack_in_tx` fenced with a snapshot SELECT under SERIALIZABLE: a peer steal committed after the ack tx's snapshot stayed invisible and the commit was not guaranteed to abort (a lone rw-antidependency does not trip SSI), so a stolen lease could ack successfully. - Fence is now a no-op self-touch UPDATE (ww-conflict ⇒ first-updater-wins 40001 on a peer steal) with a wall-clock `live_filter_clock` for a lapsed-but-unstolen lease. New `tests/postgres_fence.rs` reproduces the scenario: red before the fix, green after. coord lease acquire clock (MEDIUM): - The free-slot INSERT wrote `locked_until` from the worker clock while steal/renew bump it on the DB clock; a worker whose clock ran ahead stamped an expiry into the future, so peers (comparing against DB `NOW()`) saw the lease live long past its TTL and were blocked. Acquire now INSERTs the epoch sentinel (no worker clock) then claims the row it created with the shared DB-clock steal-UPDATE (`claim_expired_slot`), so no worker-clock value ever lands in `locked_until`. ledger FX rate sign (HIGH): - A non-positive FX rate could reach the unrealized-revaluation post path: `translate_amount` (single-amount) lacked the `rate_micro > 0` guard `translate_entry` already has, the provider-sync upsert and the raw store had no gate (only the REST ingest DTO validated), and there was no DB CHECK. A zero/negative provider quote would zero out or flip the sign of the translated position and post a wrong FX entry. Guarded at four layers: `translate_amount`, `RateSource::resolve` (skip poisoned rows so a valid fallback wins), provider-sync upsert (drop + warn, never poison the store), and a `CHECK (rate_micro > 0)` on `ledger_fx_rate` / `ledger_fx_rate_snapshot` (pg + sqlite). ledger (HIGH): - Reject negative invoice item / tax amounts at the DTO boundary — a negative `amount_minor_ex_tax` drove `deferred.clamp(0, amount)` into `min > max` (panic); `.max(0)` belt in the builder as defense-in-depth. - Stamp `posted_by_actor_id` from `ctx.subject_id()` in the local client so an in-process ClientHub caller cannot spoof the audit actor. ledger (MEDIUM): - Functional-FX columns must be a consistent pair on the direct post path (`Some`/`None` mismatch ⇒ 400) — no RateLocker there to derive one. - Route every request DTO `currency` field through `check_currency_code`. - Reject a wholly-empty invoice (no items and no tax). - Cap unbounded free-text at the boundary — `reason` (4096) / `reason_code` (64) — for both the DTOs that lower via `into_domain` and the four handler-lowered DTOs (reversal, annotation, reidentify, audit-pack) via a `pub(crate) validate()` the handler calls. e2e: - Rewrite the BOLA/no-existence-leak tests to genuinely cross tenants (seed a real entry as one tenant, assert another gets the same 404), with an owner-200 baseline. Refresh stale conftest docs (the gear is already wired into cf-gears-example-server). Verified: coord sqlite (5) + fence pg test green; ledger fx unit tests pass; 15 Postgres tests green over Docker (fence, migration-idempotency, and the revaluation / allocate / invoice-post / refund / chargeback / settlement-return FX suites); clippy clean on both crates.

Adds the Billing Ledger gear (
