Bumps the cloud-commitments-go pins (pkg, providers/aws, providers/azure, providers/gcp) from 88b95b64 to 61111428, and adapts the platform. This brings Azure Advisor reservation pricing from LeanerCloud/cloud-commitments-go#663, which closes LeanerCloud/cloud-commitments-go#655.

What changes

• Dependency bump: go.mod and go.sum, including golang.org/x/net v0.62.0.
• Typed skip counts: partial collections now read the skip count with SkippedCount(), replacing the message regex. The mixed Azure subscription-failure case now reports its skip count too, guarded against a nil Skips().
• Currency refusals: an exchange refused with common.ErrCurrencyNotAccepted now returns 422 with the refusal message, and the audit records it as failed.
• Pricing outages keep the previous rows: when Azure retail prices can't be fetched, the collection keeps the previous cycle's Advisor rows instead of evicting them. A truncated Advisor walk still evicts as before.
• Held prices can't be bought: while an account is held, Azure purchases for that account are refused as stale on every path. If the hold state can't be read, they are refused too. The hold lasts until a later collection re-prices the account, or until its rows are gone.
• Atomic write: rows, eviction and the hold marker are written in one transaction, with the marker row locked, so a scheduled run and a manual refresh that overlap can't drop a hold.
• Visible holds: the freshness payload reports held accounts under a pricing_unavailable reason, and lists held_account_ids filtered to the caller's account scope.

Release note

• Azure Advisor reservation rows for compute, database and cache now carry USD prices. They become purchasable and are checked against spend caps and plan step caps. Before, a capped grant was refused on them because the currency was unknown. Advisor Savings Plan rows stay unpriced and are still refused, as before.
• During an Azure pricing outage, the previous recommendations stay visible, but they can't be purchased until prices are fetched again.

Follow-ups

• feat(scheduler): bound the Advisor outage eviction hold and alert past it #1675: bound the outage hold and alert past it, matching on typed skip kinds once feat(azure): typed skip kinds on PartialResultError so consumers stop matching skip-reason prefixes cloud-commitments-go#670 lands. Today the match is on two library message prefixes.
• fix(purchase): classify Azure currency refusals on the purchase path #1676: classify currency refusals on the non-exchange Azure purchase path.

Summary by CodeRabbit

• Bug Fixes
  • Azure recommendations are preserved during pricing outages instead of being incorrectly removed. Freshness information identifies affected accounts, and recommendations on hold cannot be purchased until pricing is available again.
  • Successful collections clear holds for accounts that were re-priced, while holds for other affected accounts remain.
  • Held account IDs shown in freshness information are limited to the caller’s authorized account scope.
  • Collection updates keep recommendations and partial-collection status in sync, reducing the risk of inconsistent data after a failed write.
• Documentation
  • Updated API documentation to describe pricing-outage status and held account IDs.

Walkthrough

The change records Azure Advisor pricing outages as partial collection holds, carries eligible held recommendations across collection cycles, and scopes hold details in freshness responses. Azure purchase validation checks those holds. Exchange currency refusals and related dependency versions are also updated.

Independent cold review A (claude-cc-platform's cold reviewer agent, did not write the change): APPROVE 6efd10e. This verdict came after five rounds.

• Round 1 found that a truncated Advisor walk was being held as if it were an outage, so stale rows would never evict.
• Round 2 found held account IDs returned unscoped, and a read-merge-write race.
• Round 3 found that a disabled account would lose its hold while its rows stayed buyable.
• Round 4 found that the Azure filter on the stored-rows read was untested.

All are fixed at this SHA. Checked against the library at 61111428:

• every skip reason it emits, against the outage match;
• the typed accessors and the nil Skips() guard;
• the 422 mapping in both mappers;
• every purchase entry point refusing held rows, which all go through executeAndFinalize;
• the lock order against the other writers;
• the scope filter.

Mutation probes were run on each core change. internal/scheduler, internal/config, internal/api and internal/purchase pass, unit and integration. Every commit is ≤400 lines.

Open, non-blocking: the library reason strings aren't pinned in either repo (#1675, LeanerCloud/cloud-commitments-go#670).

Local verification (macOS) at this SHA, merged onto main 4dde27a4:

• full-suite build, vet and go test -race -short pass;
• go test -tags integration passes for internal/api, internal/config, internal/purchase and internal/scheduler on real Postgres.

Nothing was applied to any cloud.

Independent cold review B (claude-fleet, cold-review lane, did not write the change): APPROVE 6efd10e. This verdict came after five rounds.

• Earlier rounds found the truncation hold, the hold race and unscoped IDs, and a disabled account releasing its hold. All are fixed.
• Confirmed: every purchase entry point refuses held rows, failing closed. RI exchanges re-quote live. There's no lock cycle with any other writer, and the nil-UUID ambient key is consistent.

Non-blocking:

• the store's locking and merge are covered by integration tests only;
• incomplete_accounts is still a global count;
• there's a small check-then-act window between the rows and the freshness read in the purchase check;
• the library reason strings aren't pinned (feat(scheduler): bound the Advisor outage eviction hold and alert past it #1675).

Limit the Azure stored-row query to held accounts.

While an Azure pricing hold exists, each collection commit runs SELECT DISTINCT account_key::text FROM recommendations WHERE provider = 'azure' inside carryHoldInTx. It reads every stored Azure row while holding the recommendations_state row lock, which delays other collection commits. Restrict the query to the held account IDs and the ambient nil UUID that stillHeld reads.

Minor · Data Integrity & Integration · Poor tradeoff

Stored price and hold state are read separately, so a collection can commit after the checks.

staleAzurePricingRefusal compares the stored rows. heldAzurePricingRefusal then reads the collection freshness in a second call. Neither read runs in a transaction or under a lock, and the provider call runs after both. A collection that commits after the row comparison can replace the approved Azure price. If that collection also clears the hold, the purchase proceeds and sends the approved UpfrontCost as CommitmentCost.

The new freshness read lengthens the window between the price check and the provider call. This window predates the change.

Consider reading the stored rows and the hold state from one snapshot. Consider also re-checking the stored price immediately before PurchaseCommitment. Neither change closes the window fully, because a commit after the last check still reaches the provider with the approved price.

172-181: Trivial · Maintainability & Code Quality · Quick win

Pin the enforced 700 USD total in the cap test.

The cap checks at 600 and 1000 accept any total between 600 and 1000 without telling them apart. A total of 650 is refused at 600 and accepted at 1000, so a regression that lowers the total to 650 passes both assertions. The existing InDelta check covers only TotalCommitment(). It does not check the MaxPurchaseAmount value that purchaseConstraintSets passes to the cap comparison.

Assert that value directly. Keep the 699 and 700 boundary checks as well. Those two checks alone detect only totals outside (699, 700]. A fractional regression such as 699.50 would still pass them.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

The Azure provider update may introduce common.ErrCurrencyNotAccepted on the non-exchange purchase path, while the new 422 mapping applies only to exchange errors. The PR description explicitly lists non-exchange classification as a follow-up.

The purchase may be reported as a server failure rather than a currency refusal.

This can occur when: A direct Azure purchase is refused because its billing currency is missing or not USD.

• The subscription-prefix trim only changes <sub>: advisor: forms.
• Single-sweep behaviour is unchanged.
• The CodeRabbit finding 4 reasoning holds: it fails closed.
