| 1 — Result declarations | `resource_inspection.go` and nested diagnostic tags in `backends.go` match the selected fields and optional-pointer representation. Package-level serialization documentation still needs R1. |
| 2 — Null interpretation | `captureExecutionProfile` uses configured pointer/map presence; profile-only tri-state capture is removed. Target and isolation tests cover null/omission fallback, inherited null, empty-string clearing, map overlay, and the required-key rule. |
| 4 — Prompt resources | Prompt capture retains the resolved record, materialized messages, and required/repair presence. Prompt tests cover inherited imported text and omitted versus explicit values; inspection does not reopen sources or resolve referenced profiles/schemas. |
| 5 — Facade wiring | The internal engine's resource interface delegates to the snapshot after namespace qualification. Root conversion detaches pointers, collections, and nested diagnostics; backend not-found mapping is local to `InspectBackend`. Public error and cancellation tests pass. |
| 6 — Existing consumers | Superseded runner wrappers and their dedicated tests are removed. Execution helpers and the narrow requirement repository remain. Existing profile, inheritance, source, namespace, bundle, and preparation-example tests are migrated. |
| 7 — Generic encoding | `resource_serialization_test.go` encodes real results with ordinary JSON and YAML encoders and checks semantic keys, omission, explicit values, empty collections, diagnostic objects, and provider nulls. The existing YAML dependency is direct; its version is unchanged. |
| 8 — Isolation/selection | Public tests cover scoped backend lookup, qualified bypass, no namespace fallback, independent results, concurrent inspection/mutation, offline references, execution fallback, and retained null provenance. |
| 9 — Typed sources | `prompts.go` and `BackendSource` use explicit mapping construction with optional pointers/collections and sibling `extends`. They do not validate incomplete records, resolve inheritance, or read content files. |
| 10 — Real composition | Typed-source tests cover snapshots, layered completion, nested settings, order, inheritance, explicit values, relative file context, invalid final definitions, and empty top-level input. |
| 11 — Documentation | Main consumer, format, and internal guidance, README, and the unpublished v0.20.0 release note reflect the selected changes. Two remaining current-documentation contradictions require R1. |
This follow-up reviewed the same production revision, now at repository commit
`101a284` (the intervening commit adds only this review document). It used static
loop, call-path, ownership, and data-size analysis, not performance measurements.
The existing architecture, testing, and documentation policies apply. Explicitly
selected algorithms and dependency-owned composition/encoding were not reopened.
| Stage | Algorithmic assessment |
| --- | --- |
| 1 — Result declarations | Types and tags introduce no traversal algorithm. Optional values preserve presence without requiring consumer-side reconstruction. |
| 2 — Null interpretation | The fixed set of profile-field checks is constant-sized. Existing backend-provider overlay and target materialization are retained decisions, not new algorithms to redesign in this audit. |
| 3 — Backend/profile resources | Resolved-record indexes are captured once. Individual inspection selects one record rather than scanning the catalog; public provider-map detachment visits the selected value graph. |
| 4 — Prompt resources | Input and message loops visit their respective sequences once, but the input loop has the avoidable repeated string-key lookup described in R2. Scalar presence capture does not scan all prompts for each input. |
| 5 — Facade wiring | Namespace qualification is proportional to ID length. Pointer projection is fixed-field work; nested provider copying is proportional to the copied value graph. No per-field whole-catalog lookup is introduced. |
| 6 — Existing consumers | Removed wrappers do not leave a second resolution pass. Requirement discovery continues using the narrow metadata/snapshot path, rather than copying the expanded resource report. |
| 7 — Generic encoding | Standard JSON/YAML encoding and presence-aware result types are selected planning decisions. No Promptkit serialization round trip or generic reflection layer was added. |
| 8 — Isolation/selection | Inspection itself performs no admission, provider work, schema compilation, or file reads. Caller-owned copies scale with the selected report rather than unrelated resources. |
| 9 — Typed sources | Constructors iterate once over supplied records and their nested input/message sequences, then delegate snapshotting to ConfigKit. These are additive nested sizes, not an all-inputs-by-all-messages cross product. |
| 10 — Real composition | Tests exercise the dependency-owned loading path; no second inheritance resolver or normalization pass was added for typed sources. |
| 11 — Documentation | No production algorithm; the previously recorded documentation correction remains R1. No additional performance guarantee is selected. |
| 12 — Combined validation | The reviewed new production paths contain no additional cross-resource quadratic scan or correctness defect requiring a finding. Existing successful suite/vet results remain applicable because production code is unchanged. |
The R2 complexity analysis accounts for string-key processing, rather than
assuming every map lookup is free of key-size cost. The selected Go toolchain's
`internal/runtime/maps/runtime_faststr.go` was inspected to confirm that point.
No production implementation, test, benchmark, dependency, or public contract was
