…u sums them (#425) The receipt ledger record: pure GPU/compute accounting for remote runs — no fidelity, never feeds priors. The remote executor parses the runner's finished-payload GPU fields (gpu_sku/gpu_seconds/cost_usd, the #424 contract), emits the receipt row at settle (FAILED runs included — they burn the same GPU time), and mirrors receipt.toml into the run dir. gpuTotals() aggregates (by SKU, by status); amico ledger gpu surfaces it — the view the unit-keyed warrant fold (telaio #5) will debit. FakeCloud carries the contract fields; pre-contract runners emit no receipts and account zero.

Do not report zero spend for every ledger read error.
Lines 331-335 return zero totals for permission errors, I/O errors, and directory paths. ledger gpu can then report no spend while receipt data exists but is unreadable. Return zero only for ENOENT. Surface other read failures.

Validate parsed rows before aggregation.
JSON.parse() accepts null and arbitrary JSON values. A null line throws at rec.type. A JSON-valid but schema-invalid receipt can add strings or negative values to accounting totals. Validate each parsed value with validate(..., "ledger-record") before reading receipt fields.

Escape taskId before writing TOML.
Line 194 interpolates a remote response value into a TOML string. A task ID containing a quote or newline makes receipt.toml invalid or adds unintended TOML content. Serialize it as a TOML-safe string, as done for gpu_sku.

Test the zero boundary.
The schema requires values greater than zero. These cases reject negative values but do not reject gpu_seconds: 0 or cost_usd: 0. Add both cases to protect the exclusiveMinimum contract.

Closes #425 (client half — the cloud-side field names follow the #424 runner contract; adjustable in one place if the runner names differ when it lands).
The deeper bug this surfaced: remote/cloud solves wrote no ledger record at all — not missing GPU fields, invisible entirely. The local executor emits solve stanzas; the remote path was never wired. GPU spend couldn't be gated because it was never recorded.
What landed:
receiptledger record (schema branch + TS type): pure spend accounting —task_id/executor: remoterequired,gpu_sku/gpu_seconds/cost_usdoptional (the runner may report partially),statusfor completed/failed/aborted. No fidelity field by design — receipts can never pollute L-A priors.receipt.tomlinto the run dir (the human-inspectable artifact). Pre-contract runners: zero receipts, zero noise.gpuTotals()+amico ledger gpu: receipts / gpu-seconds (hours) / cost, by-SKU breakdown, by-status counts — the exact view the unit-keyed warrant fold (telaio β.5 — Minimal single-run inspector (stats row + live plot) #5) will debit.Verification: schema 204/204; amico-run 1037/1038 (the 1 = the pre-existing agent_spawn hermeticity leak); remote suite 25/25.
tsc --noEmitshows exactly 2 errors, both infleet_digest.ts/fleet_digest.test.ts— an unrelated in-flight branch's untracked WIP from a parallel session (see below), none in these files.Process note worth recording: this branch was assembled while a parallel session was mid-flight on the same checkout (their
428 fleet-digestwork). Untangled via pathspec-stash → branch → pop → explicit-pathspec commit; their tree was left untouched (verified disjoint hunks both directions). This is the second two-agents-one-checkout near-miss this week — the per-session worktree isolation we discussed (telaio's one-worktree-per-claim doctrine) is earning its keep for amicode dev too.Summary by CodeRabbit
