test(tools): partial-upfront guard boundaries, schema pin and accurate test names - #134
These are the remaining #129 follow-ups from the #127 review. There is no behavior change: tests and README only.
Test names. Two dry-run tests were named as if they covered every payment option, but they only exercise no-upfront. An upfront dry run does call the provider, to look up the offering read-only. They are renamed:
Partial-upfront boundary cases on the real go clients. RDS, OpenSearch, Redshift and MemoryDB each get a partial-upfront offering: a FixedPrice plus a recurring charge. Against an approved figure of 1000:
1000 and 1050.00 buy, with exactly 1 purchase call;
1050.01 is refused with go's "exceeds the approved upfront" error and 0 purchase calls.
The recurring charge stays out of the comparison, because the pinned go guard compares FixedPrice x count only. The "at approved" case would fail if it leaked in.
Schema pin. The simple tools' approved_currency enum is pinned in the registered MCP schema for all three services. It lives in a FieldOverride in Register(). Removing it fails the new test.
README. The approved-upfront bullet now says a rise of more than 5% between preview and purchase is refused, compared to the cent, matching the guard's cent rounding.
Not done, by design
Auditing a confirmed purchase that is missing approved figures. The README defines that as an argument error that writes no record, and #133 pins it with a test. The scope note on #129 explains this.
Verification
go vet ./..., go test -count=1 ./... and golangci-lint pass.
The partial-upfront fakes satisfy each client's offering matcher, so the partial path really runs.
…enum
Add partial-upfront cases (FixedPrice plus recurring charge) to the
real-client approved-upfront boundary tests for RDS, OpenSearch, Redshift
and MemoryDB, pin the simple tools' approved_currency USD enum in the
registered MCP schema, and rename the RDS no-upfront dry-run test to say
what it covers. README now states that a rise of more than 5% between
preview and purchase is refused.
Closes#129

The simple-tool dry-run test forces no-upfront, so its name overclaimed.
README now says the 5% rise comparison is done to the cent.
Closes#129
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The pull request expands upfront-price guard tests to cover partial-upfront offerings across RDS, OpenSearch, Redshift, and MemoryDB. It also clarifies README wording, specifies payment options in dry-run test names, and checks the published currency schema for simple AWS RI tools.
RDS boundary tests cover All Upfront and Partial Upfront offerings. They check the 1050.00 tolerance edge and the 1050.01 over-limit case. The README specifies cent-level comparison precision. The dry-run test name specifies No Upfront.
Simple RI boundary and schema checks tools/aws_simple_ri_upfront_guard_test.go, tools/aws_simple_ri_test.go
OpenSearch, Redshift, and MemoryDB boundary tests cover both upfront payment options. Simple-tool tests specify NoUpfront in the dry-run case and assert that each published approved_currency enum contains only USD.
The test and documentation changes are mergeable after normal checks.

Full details: Out of Scope Changes check
Explanation
The changes stay within the #129 follow-up scope. The diff summary shows changes to README.md (approved-upfront wording, matching the 5% rule) and to four test files. These files rename the no-upfront dry-run tests, add partial-upfront boundary cases for the real go clients, and pin the approved_currency enum in the registered schema. The PR states that it has no behavior change. The summary shows no unrelated product code or unrelated file scope. The schema-pin test covers the existing FieldOverride in Register() for the simple tools, and it does not change that code. The PR does not implement the #129 audit work, but that gap is a missing requirement and is assessed under linkedIssuesAssessment, not an out-of-scope change.
Full details: Linked Issues check
Explanation
[#129] requires audit records for two early returns in all five RI purchase tools (EC2, RDS, OpenSearch, Redshift, MemoryDB), with one test per tool. At the reviewed head, tools/aws_rds_ri.go returns the errors from applyApprovedFigures and previewUpfrontQuote before ExecutePurchase, and neither return calls recordPurchaseRefusal. The changed files are README.md and four test files. They add no audit code and no audit-record assertions. Unmet: (1) audit records for failed upfront dry runs that cannot price the offering; (2) audit records for confirmed upfront purchases refused for missing approved figures; (3) one audit test per tool. [#129] also asks to move the service-agnostic helpers out of tools/aws_ec2_ri_upfront.go. The changed-file list contains no such move, so this item is unmet. The PR says the missing-figures audit is out of scope and cites #133. That is a scope decision in the PR text. It does not satisfy the directly linked requirement. Items that are met: the renamed no-upfront dry-run tests, the partial-upfront boundary cases for RDS, OpenSearch, Redshift and MemoryDB, the approved_currency schema pin, and the README wording.
Resolution
In every early-return path of the five RI purchase tools, call recordPurchaseRefusal before returning: the failed upfront dry-run pricing error, and the applyApprovedFigures refusal for confirmed upfront purchases. 2. Add one test per tool that asserts the refusal audit record for these cases. 3. Move the service-agnostic helpers out of tools/aws_ec2_ri_upfront.go into a service-neutral file, with no behavior change. 4. If the missing-figures audit stays out of scope, get #129 amended or split, and remove 'Closes #129' from the PR description until the linked requirements are met or formally changed.

Add an RDS partial-upfront purchase case with count greater than one.
guardRDSArgs sets args.Count = 1 at tools/aws_rds_ri_upfront_guard_test.go:39. Every boundary case therefore compares a single instance. In that case, a per-instance FixedPrice comparison and a total FixedPrice × count comparison return the same result. The README documents the total comparison (README.md:125). The round-trip test uses count 2 at 500 per instance against 1000 approved. That test passes under either comparison, so no RDS test detects a per-instance regression.
Add a count-2 partial-upfront case. Each instance must be under the approved figure, but the total must exceed the 1050 tolerance. For example, two instances at 600 against an approved 1000 give a total of 1200. Assert that the purchase is refused with zero purchase calls.

Add a count-2 partial-upfront case to guardRDSArgs-based RDS tests, using a
per-instance FixedPrice below the approved amount but a total above the 1050
tolerance. Assert the purchase is refused and the purchase-call count remains
zero.
Add a multi-reservation refusal case to the real-client boundary test.
Every case in TestSimpleUpfrontGuardBoundaryOnRealClients calls guardArgs, which sets Count to 1. At one reservation, the unit price equals the approved total. A guard that compares the unit price instead of the total passes all of these cases.
Add a case with Count 2 for OpenSearch, Redshift, and MemoryDB, for each payment option:
Unit price: 525.01
Total: 1050.02
Approved upfront: 1000
Each service should refuse the purchase and make zero purchase calls.

Second review of 609e7b1 (2 commits; Closes #129), done in my own clone. The PR body was treated as a claim. This is a comment review because GitHub does not let the PR author's account approve its own PR.
No behavior change. The diff touches only *_test.go files and one README sentence.
The partial-upfront boundary rows really exercise the partial path. I checked each pinned go client (cloud-commitments-go39dc6e7), since a partial fake the matcher treated as all-upfront would only repeat the existing cases:
Redshift (services/redshift/client.go:362-372) has no payment option in the Regular/Upgradable offering-type enum. matchesPaymentOption decides it from the price shape, and partial-upfront means upfront > 0 and recurring > 0. The new fake branch adds exactly that: an hourly RecurringCharges of 0.05 on a positive FixedPrice.
MemoryDB (convertMemoryDBPaymentOption) and RDS (convertPaymentOption) map partial-upfront to the "Partial Upfront" offering type, which their fakes set.
OpenSearch maps it to ReservedInstancePaymentOptionPartialUpfront, which its fake sets.
A fake that didn't match would fail the tool with "no offerings found", so the passing buy rows prove the partial path ran.
The boundaries. Each service now runs approved 1000 against 1000 and 1050.00 (bought, 1 purchase call) and against 1050.01 (refused with "exceeds the approved upfront", 0 purchase calls), for both all-upfront and partial-upfront. The "at approved" row would fail if the recurring charge leaked into the comparison, since 0.05/h over a term is far above 5% of 1000. That pins the go guard's FixedPrice × count rule.
The README now says "a rise of more than 5% between preview and purchase is refused (compared to the cent)". That matches the guard's cent-rounded FixedPrice × count against approved × 1.05.
The renames (…NoUpfrontDryRunNeverCallsProvider) are accurate: both tests exercise no-upfront only, and an upfront dry run does make a read-only offering lookup.
Verification at this SHA:
go vet ./... is clean, and go test -count=1 ./... passes all three packages.
The new and renamed tests: 5 top-level pass, 0 fail, including all 12 partial-upfront subtests (RDS 3; OpenSearch, Redshift and MemoryDB 3 each).
Mutation probe: with the simple tools' "approved_currency": {Enum: []any{approvedCurrency}} override removed, TestSimpleAWSRIPurchaseRegisteredSchemaPinsApprovedCurrencyUSD fails for opensearch, redshift and memorydb, so the schema pin is real.
CI at this SHA: all 12 checks pass, and the merge state is CLEAN.
Cold review: claude-ui-fix-1, verdict APPROVE at 609e7b125e4cb4983422994fda5c3aa47569a4d7
This PR is test-only, plus a README line. I checked it against #129 and the pinned go guard, treating the PR body as a claim.
Checked
Renames. The two dry-run tests now say no-upfront, which is what they exercise. An upfront dry run does call the provider, for the read-only offering lookup.
The partial-upfront boundaries really take the partial path.
RDS, OpenSearch, Redshift and MemoryDB each get a partial-upfront offering with a recurring charge. 1000 and 1050.00 buy with exactly 1 purchase call; 1050.01 is refused with go's "exceeds the approved upfront" error and 0 purchase calls.
Probe: I turned the RDS partial fake into an All Upfront offering, and 4 subtests failed, so the partial cases depend on the partial offering matching.
The recurring charge stays out of the comparison, because the "at approved" case would fail if FixedPrice x count picked it up.
The schema pin works.TestSimpleAWSRIPurchaseRegisteredSchemaPinsApprovedCurrencyUSD reads the registered MCP schema through a real in-memory client. Probe: removing the approved_currencyEnum override in Register() (tools/aws_simple_ri.go:134) failed it for all 3 services (4 failing lines, including the parent).
README. "A rise of more than 5% between preview and purchase is refused (compared to the cent)" matches the guard's rounding.

Merge-only delta review of 609e7b12...e466a8cb. The previous head 609e7b12 had my approval and a second one. The new commit is Merge branch 'main' into test/upfront-followups. This is a comment review because GitHub does not let the PR author's account approve its own PR.
The merge adds nothing of its own. Its parents are 609e7b12 (the approved head) and 7a4738d6, which is the current main tip. git show --remerge-diff of the merge is empty, so git merged it automatically with no conflict resolution and no hand edits.
The PR's net change is unchanged. Against the merge base with current main, it is still the same 5 files: README.md, tools/aws_rds_ri_test.go, tools/aws_rds_ri_upfront_guard_test.go, tools/aws_simple_ri_test.go and tools/aws_simple_ri_upfront_guard_test.go, +117/-56. That is tests plus one README sentence, with no behaviour change. The merge brings in main's own changes (including tools/budget_state.go and tools/purchase.go), which aren't part of this PR's diff.
The new main and the PR's tests together, at this SHA:go vet ./... is clean, and go test -count=1 ./... passes all three packages. The PR's new and renamed tests pass 5 of 5 at the top level, so main's budget-state changes don't break the guard-boundary tests.
CI at this SHA: Lint, Unit Tests and both Build MCP legs were still running when I posted this.
