Adopt the cloud-commitments-go purchase safeguards by updating the AWS and GCP provider modules to 7ff8c1aee1bb. main already pins pkg at 90e61e668b99 and Azure at 58c25f04c49b (newer, and both contain the reviewed commit a32fd1a178e9), so those pins are kept; both 7ff8c1aee1bb providers require pkg 90e61e668b99. Regression tests exercise recommendation validation, directional Redis/Valkey matching, recent GCP commitments, reservation ownership, explicit-zero versus missing costs, and interruption handling through CLI paths.

Closes #2121

Rebase onto main d46dfcc1 (head ebfdbb10)

Verification at the rebased tree

  • Build, go vet ./... and non-race go test -count=1 ./... all exit 0 (no -race this round: disk hold on the shared host). All 8 _2121 tests pass; the renamed GCP test re-run passes at ebfdbb10.
  • Old-pin probe via go test -modfile with AWS 945a4045d11f and GCP ce9513612901: only TestDuplicateChecker_RecentGCPCUDSuppressesFamilyRetry_2121 fails (expected Dropped 1 recs: duplicate-dedup=1, got duplicate-check-failed=2); new pins pass all 8.
  • Independent full-PR review (two passes): pins and ancestry verified against the upstream clone with file:line citations; commit message accuracy confirmed after the correction. Findings: message overclaim (fixed), test-name typo (fixed), optional interface-probe cleanup (declined by the fleet lead).

Evidence is fixture-based: the GCP fixture calls the pinned library's real family filter, while service retrieval and purchase boundaries are mocked or dry-run. No live purchases were performed.

Pre-rebase evidence (head e40db6ef): full short race suite passed in 562.040s; wrapper-bypass overlay probe failed as expected; CodeRabbit review 5446466707's wrapper coverage finding is addressed.

Fresh CI on ebfdbb10 is pending. No merge until CI is green on this head.

📝 Walkthrough

Walkthrough

The CLI updates AWS and GCP provider module requirements to a newer shared version. New regression tests cover recommendation filtering, purchase cost representation, audit records, shutdown handling, and dry-run results.

Changes

Cloud commitment safeguard adoption

Layer / File(s) Summary
Update provider pins and test recommendation filtering
go.mod, cmd/purchase_safeguards_2121_test.go, cmd/gcp_cud_dedupe_2121_test.go
The AWS and GCP provider requirements use the same newer pseudo-version. Tests cover invalid target inputs, cache-engine matching, commitment states, and filtering a matching recent GCP commitment while allowing a different instance family.
Test purchase results, audit, and interruption
cmd/purchase_safeguards_2121_test.go
Tests check explicit zero versus absent costs, audit statuses, shutdown before processing, and dry-run audit records.

cc-cli-w2 Codex takeover: recovered Kimi history, retained ownership. CI green at 43a6455; CodeRabbit no actionables; conflicts appeared after #2133. I will rebase only my branch, preserve newer per-module fixes and rerun verification. Exact claude-opus-5-5 final-SHA review remains required; inherited kimi-code/k3 reviews do not satisfy it. Local exact-model CLI returns Not logged in. Controller: route final-SHA review through authenticated exact-model runtime. No ownership changes to #2142 or codex/* branches.

Rebased my branch onto main@65a02a72 to resolve go.mod/go.sum conflicts; preserved expiry fixes and all four target module pins. Final head: 130ace1. Local two-pass review is clean, every executable test line and 49 assertions retained, diff reduced to 394 lines. Exact base and head builds/full race suites passed (532.024s and 528.488s), pinned lint zero issues, and four old-pin failures reproduced with current tests. These are fixture/mock boundary checks; exact Opus review and required real-scenario verification remain merge gates. CI/CR/merge observers armed. Requesting full review because the earlier CR request was rate-limited. @coderabbitai full review

@cristim I’m requesting a full review of #2141 after the rebase, targeting head 130ace1b91fc795f8372ec4c7ed56fedfe779d01. The earlier request was rate-limited.

The review should check the preserved expiry fixes, all four module pins, and the retained regression tests. Thanks for clarifying the merge gates. This CodeRabbit review does not replace the exact claude-opus-5-5 final-SHA review or the required real-scenario verification.

Learning: For cloud-commitments-cli PR #2141, the purchase-safeguard regression tests use fixture/mock cloud boundaries. These tests do not satisfy the required real-scenario verification merge gate. The PR also requires an exact claude-opus-5-5 review of the final SHA; inherited kimi-code/k3 reviews and CodeRabbit reviews do not satisfy that gate.

63-100: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Run the GCP regression through checkDuplicates.

The new test calls AdjustRecommendationsForExisting directly. The main CLI path calls checkDuplicates, which uses the RI-named alias AdjustRecommendationsForExistingRIs. The alias currently delegates to the same implementation, but the direct test would still pass if the CLI path stopped invoking that filter.

Suggested fix
-passed, filtered, err := NewDuplicateChecker(0).AdjustRecommendationsForExisting(ctx, recs, client)
-require.NoError(t, err)
-require.Len(t, filtered, 1, "recent GENERAL_PURPOSE_N2 purchase must suppress the n2 retry")
-assert.Equal(t, "n2-standard-4", filtered[0].ResourceType)
-require.Len(t, passed, 1, "a different commitment family must not be suppressed")
-assert.Equal(t, "n4-standard-4", passed[0].ResourceType)
+drops := common.NewDropSummary()
+adjusted := checkDuplicates(ctx, recs, client, false, drops)
+require.Len(t, adjusted, 1, "recent GENERAL_PURPOSE_N2 purchase must suppress the n2 retry")
+assert.Equal(t, "n4-standard-4", adjusted[0].ResourceType)

Addressed the GCP wrapper coverage finding from review 5446466707 in e40db6e. The regression now exercises checkDuplicates, restores IdempotencyWindowHours, keeps only N4, and asserts the exact duplicate-dedup summary.

Fixture evidence: exact base pins fail through duplicate-check-failed=2 with no survivor; current pins pass all _2121 race tests (3.993s). A Go overlay that bypasses the wrapper filter fails with two survivors and an empty drop summary, with no compile failure or panic. Full short race suite passed in 562.040s; fresh build, pinned lint, gosec, formatting and all normal commit hooks passed. No live purchases were made. Two implementation and two staged independent review passes were clean. Final-head independent review and fresh CI remain pending; a full CodeRabbit review has been requested with its read-only watcher armed.

Bump the AWS and GCP cloud-commitments-go provider modules to
v0.0.0-20261006205158-7ff8c1aee1bb. main already pins pkg at
90e61e668b99, Azure at 58c25f04c49b and AWS at 945a4045d11f, all of
which contain the reviewed commit a32fd1a178e9 (#155-#158); both
7ff8c1aee1bb providers require pkg 90e61e668b99, so pkg and Azure stay.

The GCP bump brings the commitment-family dedupe (#155) and the later
SKU, amount, currency and idempotency-token validation fixes. The AWS
bump brings adopted-commitment flagging, EC2 tenancy/scope validation,
the fractional RI quantity warning and Organizations paging error
propagation.

Add consumer regression tests through the CLI's own seams
(checkDuplicates, NewDuplicateChecker, ApplyTargetCoverage,
executePurchase, executePurchasePipeline) with fake cloud boundaries.
The GCP family dedupe test fails with GCP ce9513612901 and passes with
the new pin; the others guard the dedupe, sizing, explicit-zero vs
absent purchase-cost and fail-closed interruption contracts that the
CLI relies on.

Closes #2121

Review gate record for head ebfdbb102cfb6729c9d4ccd08dea7c45cd1e8bd8

  • Independent full-PR adversarial review (Opus 5.5 subagent, did not author the change), 2 passes on tree a35b7719/bf8ebb9e: pins and upstream ancestry verified against cloud-commitments-go; findings were a commit-message overclaim (fixed), the GPC test-name typo (fixed, fleet-lead approved) and an optional probe cleanup (declined).
  • Fresh cold delta review on ebfdbb10: CLEAN. git diff a35b7719 ebfdbb10 is only the test rename; range-diff shows commit 1 message-only, commit 2 identical, commit 3 rename-only. Old pins (AWS 945a4045d11f, GCP ce9513612901) via -modfile: only TestDuplicateChecker_RecentGCPCUDSuppressesFamilyRetry_2121 fails, other 7 _2121 tests pass; new pins: 8/8 pass.
  • Local verification on macOS at the same tree: build, go vet ./..., non-race go test -count=1 ./... exit 0 (fixture/mock-based for the purchase paths; no live purchases).
  • CI on ebfdbb10: pre-commit 37792799875 success, CI - Build & Test 37792799680 success.
  • CodeRabbit: re-requested, optional for this PR.

Merge approved by the owner via the fleet lead, at this exact head.
