Fixes #4

Problem

A Model's provider_key_ref was translated to a ProviderKey's spec display_name in render.All, before Assemble decided which display_name that ProviderKey is actually served under. The two could disagree, so a Model could fail for a problem its ProviderKey caused, or be served on another ProviderKey's credential.

Changes

• render.All keeps the reference untranslated in Rendered.ProviderRef and no longer checks ownership.
• Assemble settles two things before every validation round, repeating until no state changes:
  • Ownership: a resource already served under a display_name keeps it, including a Retained one. Creation time decides only when no claimant is served under it. This applies to every kind.
  • References: each Model gets the display_name its ProviderKey is served under now. If that ProviderKey is Rejected or gone, the Model fails with that reason.
• Retained Models are re-checked through the stored index: the entry follows its ProviderKey's current display_name, or is rejected.
• The README describes the new ownership rule.

The ownership rule goes beyond the fix proposed in #4. With oldest-wins, a valid rename onto a display_name held by a newer ProviderKey took that ProviderKey and its Models offline. Now the rename fails and the served file stays unchanged.

Tests

Added through gatewayValidator: the issue's cases A, C and D, with both failure paths (render and gateway) and both age orders for D, plus swapped names, chained fallbacks, a replacement ProviderKey taking a deleted one's display_name, and $ in a display_name.

Summary by CodeRabbit

• Behavior Changes
  • Models now use the display name under which their referenced provider is served.
  • Existing served resources keep their display names. When no resource is already served under a claimed name, the oldest eligible resource takes it.
  • Models referencing missing or rejected providers are rejected; retained models may keep their previously served configuration when possible.
• Documentation
  • Clarified how provider display names are resolved and how conflicts are handled.

Walkthrough

Rendering now preserves Model ProviderKey references for assembly. Assembly resolves those references against ProviderKeys’ served identities and applies identity-claim, fallback, and rejection rules.

Changes: ProviderKey identity resolution

Layer / File(s)	Summary
Preserve ProviderKey references during rendering internal/render/render.go, internal/render/render_test.go	Rendering exposes the Model’s ProviderKey metadata name through ProviderRef. It no longer resolves that reference to a served identity. Tests check deferred resolution and require a nonempty reference name.
Track served identities and resolve claims internal/render/assemble.go, internal/render/assemble_test.go	Assembly records served ProviderKey ownership. Existing served identities retain their owners; otherwise, the oldest eligible claimant wins. Tests cover renames, conflicts, swaps, and fallback claims.
Resolve Model references through assembly internal/render/assemble.go, internal/render/assemble_test.go, README.md	Assembly sets each Model’s ProviderKey identity from the referenced ProviderKey’s served name. Missing or rejected references cause fallback or rejection. Tests cover retained Models, validation failures, and escaped dollar signs. The README describes the served-name ownership rule.

Estimated code review effort: 4 (Complex) | ~40 minutes

Possibly related issues

• api7/aisix-controller issue 18: The issue includes Model routing after a ProviderKey rename; this change defers reference resolution to assembly and uses the served identity.
• api7/aisix-controller issue 9: The issue describes an older rename displacing an already-served resource; this change preserves the existing served owner of an identity.

Merge Risk: Minimal · up to ac275

This change resolves Model provider references against the ProviderKey's served display name during assembly, which addresses the same-namespace misrouting described in the linked issue. No concrete merge-blocking risk was identified, and the change adds tests for the main rename, swap and rejection cases.

Explanation

Issue [#4] coding requirements are met. render.All now preserves Rendered.ProviderRef and does not perform ownership or served-name resolution. Assemble resolves each Model during every settlement round against the ProviderKey item state, uses the current or retained served identity, and reports a rejection reason when the ProviderKey is missing or rejected. fallback rebuilds retained Models from the stored index and rechecks their ProviderKey owner. claim moves ownership handling into assembly and preserves an existing served claimant, including a Retained claimant. Tests cover the requested failed rename, collision, retained-name, and model-resolution paths through gatewayValidator, plus the documented edge cases.

Full details: Out of Scope Changes check

Explanation

The changes stay within issue [#4]. The ownership rule, settlement logic, retained-entry handling, README update, and added tests directly support provider reference correctness and the requested resolver change. No unrelated production feature or unrelated test change is evident in the reviewed diff.

Full details: Security Check

Explanation

No matching security issue was found in the changed code. The review covered all seven categories: 1. Sensitive data exposure: No issues found. 2. Unencrypted database secrets: No issues found. 3. Authorization bypass: No issues found. 4. Cross-resource ownership: No issues found. 5. TLS and cryptography: No issues found. 6. Shared resource safety: No issues found. 7. Secret reference resolution: No issues found. The changes move ProviderKey ownership and Model reference resolution into assembly. The controller supplies same-namespace resources, and assembly rejects a Model when its referenced ProviderKey is absent or rejected.

Full details: E2e Test Quality Review

Explanation

❌ Blocking: Missing E2E coverage. The new tests call All and Assemble directly (internal/render/assemble_test.go:97-108). Even with the real validator, they do not exercise the controller and gateway request flow. The existing E2E test uses one ProviderKey and does not test a ProviderKey rename or name collision (test/e2e/run.sh:155-215).

Resolution

Add E2E tests for rejected renames and ProviderKey name collisions. Apply the resources through Kubernetes, check their status, and send gateway requests that verify the intended upstream credential.
