Compare the audit status with the purchase result.
This assertion passes when a failed purchase is recorded as "success". Compare rec["status"] with the corresponding purchase report row, or use a controlled failing client and require "error". The regression test then checks the per-recommendation status required for reconciliation. (github.com)

Make the preflight test detect CSV-read ordering.
The current CSV is readable. The test would still pass if runToolFromCSV read it before checking the audit log. Set CSVInput to a nonexistent path and retain the assertion that the audit-log error wins. That checks the required order directly. (github.com)

Stop the purchase run when an audit write fails.
If the audit log fills or becomes unwritable after preflight, writePurchaseAuditRecord logs a warning and the CSV loop continues purchasing. Those purchases can finish without the records needed to reconcile a partial run. Return the write error to the purchase pipeline and stop further purchases; report the failure to the CLI caller. The pinned audit writer explicitly returns I/O errors, while its writability check only opens and closes the file. (github.com)

Write each CSV audit record before the purchase delay.
For every real purchase except the last in a region, processPurchaseLoop sleeps after executePurchase and before this write. If the process terminates during that delay, the purchase has no audit record. Move the write immediately after the purchase result is available, as executePurchasePipeline already does. (github.com)

…se path cudly --input-csv X --purchase moved real money but wrote zero audit records: processPurchaseLoop (the CSV path's purchase loop) never called common.WriteAuditRecord, unlike executePurchasePipeline on the non-CSV path. The CSV path also never called CheckAuditLogWritable, so even the pre-flight guarantee that a record could have been written was absent. On a partial failure there was no durable, per-recommendation record of which rows succeeded, so an operator could only re-run the whole file -- a double purchase for the rows that already succeeded. Extracted writePurchaseAuditRecord out of executePurchasePipeline so both purchase entry points (the main pipeline and processPurchaseLoop) share it: every recommendation that reaches a purchase attempt, dry run or real, is now recorded to cfg.AuditLog regardless of which path produced it. processPurchaseLoop and the legacy processRegionRecommendations path now thread a runID through so every recommendation carries a run ID grouping it with its invocation, matching the non-CSV path. CheckAuditLogWritable now runs at the top of runToolFromCSV, before the CSV is even read, matching the non-CSV path's pre-flight check. Extracted prepareCSVPurchaseRun out of runToolFromCSV, and added a purchaseAuditStatus helper, to keep both functions under the project's gocyclo budget after adding the new branches. Regression tests: - TestRunToolFromCSV_WritesAuditRecordsOnPurchaseRun runs runToolFromCSV with ActualPurchase=true and invalid AWS credentials (so the purchase call fails the same way a real AWS error would) and asserts the audit log contains one record per recommendation with a run ID, source=cli, and a success/error status. - TestRunToolFromCSV_ChecksAuditLogWritability asserts an unwritable audit-log directory is rejected before the CSV is even read. Proved both fail on the pre-fix code: built a detached worktree of origin/main at this branch's base (12fe838) with only the two new test functions applied (as a standalone file, since the full test-file diff also carries unrelated processPurchaseLoop signature-adaptation edits that don't compile against the pre-fix signature). Both fail as expected: no audit file is created, and the writability check never runs. Every existing test that reaches processPurchaseLoop now needs its own AuditLog, or it will write real records into wherever the default resolves to. Set toolCfg.AuditLog on every existing test call site that reaches the purchase loop, and added a TestMain that points the shared toolCfg.AuditLog default at a process-scoped temp file as a safety net so a test that reaches the loop without an explicit override does not silently create a stray cmd/cudly-audit.jsonl file in the repo working directory. Verification: go build ./cmd, go vet ./cmd/..., golangci-lint v2.10.1 (the exact CI pin) run --timeout=10m clean, gocyclo -over 10 clean, go mod tidy -diff empty, go test -race -short ./... all green, and no stray files left in the working tree after the full run. Closes #1609
…e loop level Rebased onto origin/main, which merged #1941 (fail-closed duplicate check) and #1942 (fail-closed --target-coverage) after this branch's base. #1941 changed CI's outcome for this PR's purchase-run test: TestRunToolFromCSV_WritesAuditRecordsOnPurchaseRun drove a real purchase through runToolFromCSV with invalid AWS credentials, relying on the purchase call itself failing. Post-#1941, the duplicate check now fails closed first on those same invalid credentials and refuses the region before ever reaching a purchase attempt, correctly writing no audit record by design -- so the test's audit file was empty and json.Unmarshal("") failed with "unexpected end of JSON input" in CI (the PR's base predated #1941 locally, so the old behavior still ran there, which is why it passed locally and failed in CI). Replaced that test with two more targeted ones: - TestRunToolFromCSV_WritesAuditRecordsOnDryRun exercises the full --input-csv entry point (prepareCSVPurchaseRun's runID -> processPurchaseLoop -> writePurchaseAuditRecord) via a dry run, which #1941 does not affect (the duplicate check only warns and continues on a dry run). - TestProcessPurchaseLoop_WritesAuditRecordForRealPurchase exercises processPurchaseLoop directly with a mocked provider.ServiceClient (table-driven over PurchaseCommitment success and error), the same technique TestProcessPurchaseLoopActualPurchase already uses to test real-purchase behavior without live AWS credentials -- createServiceClient is not injectable, so this is the only way to observe a real purchase attempt's audit status deterministically. Both new tests assert the audit file is non-empty before splitting it into lines, so an empty-file bug fails loudly at that assertion rather than making the length check pass vacuously and failing confusingly at json.Unmarshal. Also had purchaseSingleRec call the purchaseAuditStatus helper instead of duplicating its two-line success/error branch inline. Filed #2103 (p2) for a related gap surfaced while reviewing this: a failed audit-record write mid-run currently logs a warning and lets the purchase loop continue rather than stopping further purchases once the audit trail can no longer be trusted -- out of scope for this fix, which is about the audit trail existing on the CSV path at all. Verification: go build ./cmd, go vet ./cmd/..., golangci-lint v2.10.1 (the exact CI pin) run --timeout=10m clean, gocyclo -over 10 clean, go mod tidy -diff empty, go test -race -short ./... all green (437s), no stray files in the working tree afterward. Proved the new dry-run CSV test fails on the pre-#1609 code (built a worktree of origin/main, which already includes #1941+#1942, with only that test applied): it fails with "a purchase run through --input-csv must write an audit log" since no audit record was written pre-fix. The processPurchaseLoop test fails to compile against the pre-#1609 signature (which has no runID parameter), which is itself evidence of the same gap.

Summary
cudly --input-csv X --purchasemoved real money but wrote zero auditrecords.
--audit-logwas silently inert in CSV mode, and unlike thenon-CSV path the run never even checked that the log was writable before
touching AWS.
Root cause
git grep -n "WriteAuditRecord\|NewAuditRecord\|CheckAuditLogWritable" -- cmd/on the base commit returns three non-test hits, and all three are on the
non-CSV path (
executePurchasePipelineandCheckAuditLogWritableinrunToolMultiService).runToolFromCSVdispatches real purchases throughprocessPurchaseLoop->executePurchaseand never constructs anAuditRecord, and never callsCheckAuditLogWritable.On a partial failure there was no durable, per-recommendation record of
which rows succeeded, so an operator could only re-run the whole file --
which is a double purchase for the rows that already succeeded.
Fix
writePurchaseAuditRecordout ofexecutePurchasePipelinesoboth purchase entry points (
executePurchasePipeline, the main pipeline,and
processPurchaseLoop, the--input-csvpath) share it. Everyrecommendation that reaches a purchase attempt, dry run or real, is now
recorded to
cfg.AuditLogregardless of which path produced it.processPurchaseLoopand the legacyprocessRegionRecommendationspathnow thread a
runIDthrough so every recommendation carries a run IDgrouping it with its invocation, matching the non-CSV path.
CheckAuditLogWritablenow runs at the top ofrunToolFromCSV, beforethe CSV is even read, matching the non-CSV path's pre-flight check.
prepareCSVPurchaseRunout ofrunToolFromCSV, and added apurchaseAuditStatushelper, to keep both functions under the project'sgocyclo budget (
-over 10) after adding the new branches.Regression test
TestRunToolFromCSV_WritesAuditRecordsOnPurchaseRunrunsrunToolFromCSVwith
ActualPurchase=trueand invalid AWS credentials (so the purchasecall fails the same way a real AWS error would) and asserts the audit log
contains one record per recommendation with a run ID,
source=cli, and asuccess/error status.
TestRunToolFromCSV_ChecksAuditLogWritabilityasserts an unwritableaudit-log directory is rejected before the CSV is even read.
Proved both fail on the pre-fix code: built a detached worktree of
origin/mainat this branch's base (12fe8389) with only the two new testfunctions applied as a standalone file (the full test-file diff also
carries unrelated
processPurchaseLoopsignature-adaptation edits thatdon't compile against the pre-fix signature). Both fail as expected: no
audit file is created, and the writability check never runs.
A note on existing-test fallout
Every existing test that reaches
processPurchaseLoopnow writes realaudit records wherever
cfg.AuditLogresolves to. I settoolCfg.AuditLogon every existing test call site that reaches the purchase loop, and added
a
TestMainincmd/main_test.gothat points the sharedtoolCfg.AuditLogdefault at a process-scoped temp file, as a safety net so a test that
reaches the loop without an explicit override doesn't silently create a
stray
cmd/cudly-audit.jsonlfile in the repo working directory on everygo testrun.Verification
