fix(deps): adopt the latest reviewed cloud-commitments-go purchase safeguards - #136
Adopts the reviewed cloud-commitments-go purchase-safety fixes. All four modules (pkg, providers/aws, providers/azure, providers/gcp) move together from v0.0.0-20261104073158-39dc6e76ed43 to v0.0.0-20261105181516-07b7b48d9463 (go main 07b7b48d). There are no replace directives, and go mod verify passes.
The fixes this brings in:
#682: Cost Explorer RI quantities are rounded down, with their costs scaled to match.
#684: a purchase count that doesn't fit int32 is refused before any AWS call.
#685: GCP lists only live commitments.
#688: exchange targets keep the source RI's offering type. The MCP server does no RI exchange lookups, so this change doesn't affect it.
Search recommendations now exclude reservation options with a count of zero while continuing to show Savings Plan options, including those with a count of zero. This keeps zero-count reservations out of results without hiding Savings Plans.
Chores
Updated underlying service components; no other user-facing changes are noted.
…feguards
Bumps all four cloud-commitments-go modules together to go main, which
adds the purchase-safety fixes reviewed since the previous pin: RI
quantities from Cost Explorer are rounded down with their costs scaled
(#682), GCP lists only live commitments (#685), exchange targets
keep the source RI's offering type (#688), and purchase counts that do
not fit int32 are refused before any AWS call (#684). The MCP server does no RI
exchange lookups, so the offering-type requirement does not affect it.
No replace directives; go mod verify passes.

Walkthrough
The PR filters recommendations with counts below one, except for Savings Plans, and adds tests for those cases. It also updates several dependency versions in go.mod.
Changes: Recommendation count filtering
Layer / File(s)
Summary
Filter recommendations by count tools/search_recommendations.go, tools/search_recommendations_fanout_test.go
fetchSearchCombos omits recommendations with Count < 1 unless they are Savings Plans. Tests cover zero-count reservations, positive-count reservations, and zero-count Savings Plans.
Dependency version updates
Layer / File(s)
Summary
Dependency requirement updates go.mod
The four cloud-commitments-go requirements use revision 20261105. Several AWS, Google Cloud, gRPC, CEL, Redis, and Envoy dependencies also use updated versions.
LeanerCloud/cloud-commitments-mcp#123: Both PRs involve the cloud-commitments-go library used by the EC2 purchase path. The available evidence does not confirm that this dependency update changes the price guard.

Explanation
[35] The four modules move together to 07b7b48d9463. The new recommendation filter and tests support the rounding change. The issue requires recent matching GCP CUDs to suppress recommendations. The PR describes flag-only behavior and reports a later owner decision, but the decision text is not available here. The PR also reports existing protocol and old-pin/new-pin regressions, but the available evidence does not establish their coverage or results. The reported short tests do not establish race-short results.
Resolution
Provide the owner decision on the GCP requirement, the protocol test coverage and old-pin/new-pin results, and the server/tools race-short results.

Cold review of 886b1ab (Closes #35), done in my own clone. It is 0 behind main and merges cleanly. The PR body was treated as a claim. The diff is go.mod and go.sum only: all four cloud-commitments-go modules move from 39dc6e76ed43 to 07b7b48d9463, plus transitive moves.
Module hygiene and build (GOWORK=off GOMAXPROCS=4 GOFLAGS=-p=2)
go mod verify reports all modules verified, and go mod tidy -diff shows no changes, so go.sum matches go.mod. There are no replace lines.
go build ./... and go vet ./... are clean.
go test -short -count=1 ./... passes for the root, cmd/cudly-mcp and tools.
The go APIs the MCP uses, against what changed
#688 (OfferingType required on exchange targets). The MCP calls none of FindConvertibleOffering, LookupOffering, RIMetadataInfo, ListTargetOfferings or pkg/exchange (grep over all non-test .go files), so no MCP tool builds an exchange target, and the new required field can't be missed. The body's statement holds.
#684 (int32 count refusal). The MCP tool schemas take count as an int that "must be > 0", with real purchases capped by the spend caps (tools/spend_caps.go, EnvMaxCount), so a count above MaxInt32 isn't reachable through a capped real purchase. If it were, #684 refuses before any AWS call, wrapping common.ErrRefusedBeforePurchase in both the returned error and PurchaseResult.Error. refusedBeforePurchase (tools/budget.go:126-139) then releases the budget reservation, which is the right outcome when nothing was sent.
#679 (Azure retry errors now wrap ErrOutcomeUnknown) isn't named in the body, but it is in the range. refusedBeforePurchase refuses to release anything carrying ErrOutcomeUnknown (budget.go:132), and tools/audit.go:68 and tools/purchase.go:299 treat it as unknown. So those retries now stay counted and are audited as unknown. That's the stricter, safe direction, with no code change needed.
#682 (RI quantities rounded down, costs scaled) and #685 (GCP lists only live commitments) change values coming from the library. The MCP has no rounding of its own, and the tools suite, which includes the search and purchase-guard tests, passes.
#678 and #681 (Azure PartialResultError skip kinds), #686 (ladder observed rates) and #677 (ListTargetOfferings page cap) add or change APIs the MCP doesn't call (no PartialResultError, SkipKinds, ObservedCommitmentRate or ListTargetOfferings use).
Pins, tidy, vet, build and short suites: confirmed above.
Protocol harness and old-pin red / new-pin green regressions: the 2026-10-09 comment on #35 maps them to #43, #50 and #53. The cited harness files still exist at this head (cmd/cudly-mcp/gcp_purchase_protocol_test.go, cmd/cudly-mcp/search_dedupe_protocol_test.go) and pass in the cmd/cudly-mcp suite.
Recent matching GCP CUDs: the owner decision on #35 (2026-11-05, option A) makes the flag-only possibly_covered enough.
CI at this SHA was still queued or running when I posted this.
Not blocking
The body lists four go fixes, but the range 39dc6e76..07b7b48d also brings #675, #677, #678, #679, #681, #686 and four dependency-group bumps (#664 to #667). None changes an API the MCP calls in a way that matters, and #679 tightens budget release. A sentence noting the rest of the range would keep the pin bump's record complete.
Cold review (non-author) of origin/main...886b1abf: one commit, go.mod +17/-17, go.sum +34/-34.
Pins. All four cloud-commitments-go modules move together from 39dc6e76 to 07b7b48d. There are no replace directives. The other go.mod changes are indirect transitive bumps (aws-sdk config, credentials, sso, ssooidc, costexplorer, organizations, signin; grpc; cel; redis; resourcemanager; envoy).
What the range brings, checked against what the MCP uses. The range 39dc6e76..07b7b48d holds 14 commits, more than the four the body names.
#684, a count that doesn't fit int32 is refused: the MCP purchase tools pass args.Count (tools/aws_ec2_ri.go:232, and the same in the elasticache, rds, simple and azure tools, plus VCPUCount for GCP at gcp_computeengine_cud.go:169). Each already refuses counts of 0 or below (:212 and siblings), and spend_caps.goEnvMaxCount caps rec.Count, so the int32 refusal is a second guard behind the MCP's own cap.
#688, which keeps the source RI's payment option on exchange targets (8344b3d): the MCP builds no exchange target. A grep for pkg/exchange, ExchangeTarget and OfferingType in non-test code finds nothing, so it's unaffected. #682 (rounded quantities), #685 (live GCP commitments) and #675 (more Azure Advisor rows) change only recommendation and inventory data, not API shapes.
#679, Azure reservation retry errors marked outcome-unknown: the MCP already branches on common.ErrOutcomeUnknown in tools/audit.go:68, tools/budget.go:132 and tools/purchase.go:299. Such a failure is now treated as unknown rather than a refused-before-purchase failure, which is the more conservative path for the budget and the audit trail.
#678/#681 (typed skip kinds on PartialResultError), the EC2 ListTargetOfferings page cap, and ladder observed rates: none of these types or calls is used by the MCP (grep of non-test code).
Acceptance (#35). The body's mapping matches the 2026-10-09 item-by-item comment. The last open item ("recent matching GCP CUDs") is settled by the owner's 2026-11-05 Option A: flag-only possibly_covered.
Local verification (macOS, scratch worktree at the SHA, GOWORK=off, throttled GOMAXPROCS=4, -p 2):
go mod verify: all modules verified.
go mod tidy -diff: clean.
go build ./... and go vet ./...: pass.
go test -short ./...: root package, cmd/cudly-mcp and tools all ok.
CI was partly still running when I checked (4 passed, 5 pending).

Since cloud-commitments-go#682 the library rounds fractional Cost Explorer
RI quantities down, and a quantity below 1 becomes a row with Count 0
that the parser keeps (it only logs a warning). search_recommendations
offered that row although it cannot be bought and the purchase guard
refuses Count 0. fetchSearchCombos now skips non-Savings-Plan rows with
Count below 1; Savings Plans are sized by hourly commitment and always
stay. Tests cover a dropped zero-count reservation and a kept zero-count
Savings Plan.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Delta review of 886b1abf...fb2277d9, one commit: "fix(tools): drop reservation rows whose quantity rounded down to zero". I approved 886b1abf. It is 0 behind main.
The change (tools/search_recommendations.go, fetchSearchCombos). Each fetched recommendation is now kept unless it's a non-Savings-Plan row with Count < 1.
Why Count < 1 is the right test for every non-SP type. I checked this in the go version the PR pins (07b7b48d9463). Every non-Savings-Plan commitment type is bought by Count, and every provider refuses a count below 1:
AWS reservations: refused outside [1, MaxInt32] since #684.
GCP CUDs:Count is the vCPU amount, and computeengine refuses rec.Count <= 0 (providers/gcp/services/computeengine/client.go:800-801).
Azure reservations: refused with "quantity must be greater than zero".
So a Count-0 row from #682's rounding down could never be bought, and dropping it from search is correct. Savings Plans are sized by hourly commitment, not Count, and are exempt, as they should be.
Verification (GOWORK=off GOMAXPROCS=4 go test -p 2 -short ./tools/, under the shared review lock):
go vet ./tools/ is clean, and ./tools/ passes.
Fail-before: with search_recommendations.go reverted to 886b1abf, TestSearchRecommendationsDropsZeroCountReservations fails, and TestSearchRecommendationsKeepsSavingsPlansRegardlessOfCount passes, as expected since the old code dropped nothing.
Mutations (each reverted):
Count < 0 instead of < 1: killed;
the Savings Plan exemption removed: killed (the SP test fails).
Cold approvals at 886b1ab from nibblets and qa-ui-3, then delta approvals from both at fb2277d for the zero-count fix.
CI green at the head. 0 unresolved threads (the CodeRabbit finding was fixed and resolved). Merge state CLEAN.
mcp main was unchanged since the tests ran (92b5219).
Local checks: build, vet, the short suites for all three packages, and golangci-lint all pass. The new zero-count test failed before the fix.
mcp#35 is closed by this merge.
