# Consolidated Pre-1.0 Audit Catalog

Consolidated on 2026-11-04 from the 11 audit documents in this directory.
Their 41 numbered findings are represented by 34 entries below. Entries that
describe the same underlying issue share one remediation scope; missing
regression coverage for an identified defect is included with that defect.
Some broad testing findings consequently support more than one entry.

The order reflects consequence, exposure, and the value of clarifying public
contracts before v1.0. Confirmed defects and conditional security exposure come
first, followed by contract/test gaps, resource efficiency, and maintainability.
This ordering does not upgrade the original severities or turn every cleanup
into a release gate. The source audits retain their evidence, qualifications,
and validation results. None of these entries is marked remediated by this
documentation-only consolidation.

## 1. Update The Audited Maintainer Toolchain For Applicable Security Fixes

**Conditional security exposure.** The audited Go 1.27.0 toolchain predates
networking fixes applicable to HTTP clients, including HTTP/2 CPU exhaustion
and conditional certificate-trust exposure. Use a patched maintainer toolchain
and repeat the focused security assessment against it. Actual downstream
exposure depends on the toolchain that builds the consumer and its transport
and trust configuration; raising PromptKit's minimum Go requirement is a
separate compatibility decision, not an implied remedy.

## 2. Bound Authentication-Probe Response Consumption

**Confirmed resource/security defect.** Authentication diagnostics read a
successful upstream body with unbounded `io.ReadAll`. A deadline does not bound
the bytes a fast server can supply. Introduce finite response consumption and
clean closure, with an explicit choice of byte budget and overflow reporting.
Overflow should not be interpreted as proof of rejected authentication.
Relocating the provider adapter in entry 26 would not itself fix this defect.

Sources: [Resources 1](05-resources.md#1-authentication-diagnostics-read-an-unbounded-upstream-body),
[Security 2](07-security.md#2-authentication-probes-permit-unbounded-remote-body-memory-consumption).

## 3. Avoid Exponential Expansion During Convenience Source Conversion

**Confirmed resource defect.** `ProfileSource` and `BackendSource` conversion
expand repeated references before ConfigKit performs its bounded snapshot.
A small shared acyclic graph can therefore cause exponential work and
allocation. Preserve shared references during conversion, with suitable cycle
and slice-view handling, rather than duplicating ConfigKit's validation or
introducing PromptKit-side raw-source limits. Add focused shared-graph and
deferred-failure regressions for both convenience helpers.

Sources: [Resources 2](05-resources.md#2-convenience-source-conversion-expands-shared-graphs-before-bounded-loading),
[Testing 3](08-testing.md#3-programmatic-provider-value-conversion-lacks-representative-value-cases).

## 4. Resolve The ArtifactReader Buffer-Ownership Contract

**Confirmed race under the documented collaborator contract.** The public
reader contract permits buffer reuse after `Read` returns, before PromptKit
can finish copying it. Concurrent preparation with a compliant custom reader
can race. Clarify ownership/lifetime per invocation and align adapters, GoDoc,
and concurrency tests. This needs a deliberate public-contract decision before
v1.0: an immediate copy alone cannot guarantee safety if the reader is allowed
to mutate the buffer immediately. No default-reader defect was established.

Sources: [Interfaces 1](09-interfaces.md#1-artifactreader-permits-buffer-reuse-before-promptkit-can-copy-it).

## 5. Preserve Exact Numbers In Programmatic Provider Sources

**Confirmed data-integrity defect.** Convenience source conversion falls back
from integer parsing to `float64` without checking precision, silently changing
some accepted `json.Number` values. Preserve an exact ConfigKit-compatible
representation, or defer an unsupported-value error to ConfigKit instead of
rounding or converting the number into a string. Regression coverage should
include exact-number boundaries, nested typed collections, mutation isolation,
and deferred unsupported/cyclic-value errors for both source helpers.

Sources: [Correctness 1](01-correctness.md#1-provider-source-helpers-silently-change-exact-json-numbers),
[Testing 3](08-testing.md#3-programmatic-provider-value-conversion-lacks-representative-value-cases).

## 6. Make Provider-Native Schema Constraints Self-Contained

**Confirmed implementation gap; packaging policy needs selection.** Local
validation freezes referenced schema resources, but the provider receives only
the root document and cannot resolve its local external references. Select
correct resource packaging, or an explicit local-only fallback policy, without
naively inlining recursive schemas or silently dropping native constraints.
Add a wire-level regression demonstrating a usable provider constraint, not
merely successful local compilation. Entry 21 is a separate compilation
refactor and does not solve this packaging problem.

Sources: [Correctness 2](01-correctness.md#2-external-schema-resources-do-not-reach-the-provider-constraint),
[Testing 5](08-testing.md#5-multi-resource-schema-tests-do-not-establish-a-usable-provider-constraint).

## 7. Preserve The Owning Operation's Public Error Category

**Confirmed classification defect.** Public error conversion searches nested
causes in a global priority order, allowing a collaborator's sentinel to hide
the enclosing operation's category. Map the owning boundary independently
while retaining the original cause for `errors.Is`/`errors.As`. Add composed
cause regressions; simply reordering global checks can break legitimate direct
not-found versus load-failure distinctions.

Sources: [Error handling 1](06-error-handling.md#1-nested-collaborator-errors-can-hide-the-owning-operations-public-category),
[Testing 4](08-testing.md#4-error-tests-miss-composed-causes-and-pre-dispatch-diagnostic-failures).

## 8. Distinguish Response Stream Failures From Malformed JSON

**Confirmed error-handling defect.** Non-context I/O failures while decoding a
successful HTTP response or checking its end are reported as malformed JSON,
losing the transport cause; complete JSON followed by a read failure can also
be misreported as trailing data. Retain and classify reader failures separately
using the existing redacted transport boundary. Preserve cancellation
precedence and genuine malformed/truncated/oversized-content handling. Cover
both read locations without adding transport retries.

Sources: [Error handling 2](06-error-handling.md#2-successful-status-body-read-failures-are-misreported-as-malformed-json),
[Testing 4](08-testing.md#4-error-tests-miss-composed-causes-and-pre-dispatch-diagnostic-failures).

## 9. Return Invalid Diagnostic Request Construction As A Go Error

**Confirmed diagnostic-contract defect.** Some invalid inference settings fail
before dispatch yet produce a completed report with a nil Go error. Propagate
local request-construction failures through `ErrInvalidRequest` and add a
no-dispatch regression. Preserve intentionally completed diagnostic outcomes
for missing credentials, capacity outcomes, and unsupported or inapplicable
operations; not every no-dispatch outcome is invalid configuration.

Sources: [Error handling 3](06-error-handling.md#3-inference-diagnostics-swallow-some-invalid-request-construction-errors),
[Testing 4](08-testing.md#4-error-tests-miss-composed-causes-and-pre-dispatch-diagnostic-failures).

## 10. Remove Quadratic Requirement-Evidence Union Work

**Confirmed algorithmic inefficiency.** A left-heavy recognized condition can
repeatedly copy growing missing-key evidence sets, producing quadratic work.
Use operation-local accumulation or ownership-aware merging while preserving
classification and conservative inspection coverage. Do not address this by
adding expression limits or expanding the recognized template language. Entry
23's traversal cleanup is related but is not a substitute for fixing this
specific accumulation algorithm.

Sources: [Efficiency 1](02-efficiency.md#1-condition-evidence-unions-can-require-quadratic-work).

## 11. Exercise RunRequest's Privacy Formatting Boundary

**Missing protection, not a demonstrated leak.** Request formatting methods
have no execution coverage despite owning a privacy-sensitive public boundary.
Add focused tests with distinct synthetic private markers for the relevant
value/pointer formatting paths and JSON omission behavior. Assert privacy and
the documented boundary, not an incidental complete diagnostic or JSON shape.

Sources: [Testing 1](08-testing.md#1-runrequests-privacy-formatting-contract-is-not-exercised).

## 12. Correct Profile Inspection Credential Documentation

**Public-contract documentation defect.** Inspection GoDoc incorrectly makes
required credentials and an environment variable mutually exclusive. Actual
behavior permits an explicit profile environment variable while suppressing
only the backend-derived default when required credentials are selected.
Correct the field/method GoDoc and consumer example, keeping the established
configuration behavior and DTO shape.

Sources: [Interfaces 2](09-interfaces.md#2-profile-inspection-misstates-required-credential-semantics).

## 13. Correct The Configured Provider-Map Wire Documentation

**Integration-contract documentation defect.** The wire document says backend
and profile provider maps replace one another, but configuration recursively
overlays them; runtime replacement is a separate rule. Align the integration
summary with the canonical format reference rather than maintaining a second
conflicting precedence definition. Entry 19 concerns the efficiency of the
existing overlay, not a change to its semantics.

Sources: [Interfaces 3](09-interfaces.md#3-the-wire-contract-incorrectly-says-configured-provider-maps-replace).

## 14. Remove Stale Identity And Version GoDoc

**Public-contract documentation defect.** Inspection comments still describe
trimmed profile IDs, and listing comments describe a removed prompt-version
field. Update them to the implemented literal identity and current collection
version model. Do not normalize meaningful whitespace or reintroduce a field
to match obsolete comments.

Sources: [Interfaces 4](09-interfaces.md#4-identity-godoc-still-describes-removed-normalization-and-version-fields).

## 15. Cover The Public Single-Schema-File Option

**Public wiring coverage gap.** Direct filesystem-validator tests do not
exercise `WithSchemaFile` through engine construction. Add offline temporary
file cases through public preparation/validation, including option precedence
and relevant file errors. This is a supported feature, not dead code; entry
32 removes only an unused private helper result.

Sources: [Testing 2](08-testing.md#2-the-public-single-schema-file-option-has-no-execution-coverage).

## 16. Detach Inert Prepared Handles From The Execution Owner

**Avoidable retention.** Used or discarded prepared handles retain their
runner, and therefore the engine's captured configuration and collaborators.
Use a narrower ownership identity or clear the unnecessary owner reference
safely. Preserve foreign-owner rejection, one-time claim, namespace-view
behavior, and available details. This is unnecessary retention when a handle
outlives its engine, not evidence of an ever-growing global leak.

Sources: [Resources 3](05-resources.md#3-inert-prepared-handles-retain-their-entire-execution-owner).

## 17. Bound Repair Feedback's Temporary Serialization

**Avoidable peak allocation.** Feedback formatting serializes potentially
large diagnostic text before truncating the final message, so its existing
output bound does not bound scratch memory. Produce bounded encoded feedback
incrementally, preserving the existing output semantics and complete stored
validation diagnostics and previous candidate. A new raw-diagnostic input
limit is not implied.

Sources: [Resources 4](05-resources.md#4-repair-feedbacks-output-bound-does-not-bound-its-temporary-serialization).

## 18. Detach Normalized Session IDs From Large Input Strings

**Avoidable retention.** A short trimmed session ID can retain the allocation
of a much larger padded caller string. Clone the accepted normalized value at
its ownership boundary. Preserve trimming, accepted content, code-point
validation, and resulting wire/hash content rather than adding a raw-input
size restriction.

Sources: [Resources 5](05-resources.md#5-short-normalized-session-ids-can-pin-large-input-strings).

## 19. Avoid Repeated Descendant Cloning During Provider Overlay

**Construction-time inefficiency.** Recursive overlays repeatedly clone and
sort overlapping descendant maps, giving work proportional to tree size times
depth. Existing depth bounds mean this is not unbounded quadratic growth.
Clone ownership once or use a single traversal while retaining recursive-map,
null, and array semantics. Coordinate with entry 24 without assuming all JSON
walkers have interchangeable policies.

Sources: [Efficiency 2](02-efficiency.md#2-recursive-provider-overlay-repeatedly-clones-descendant-subtrees).

## 20. Index Filtered Listings By Namespace

**Repeated inspection overhead.** Filtered listing currently copies and scans
the complete inventory even when few or no entries match. Capture namespace
buckets or equivalent ranges so queries operate on the relevant subset.
Preserve ordering, exact identity matching, cancellation, and caller-owned
results. A pagination API or runtime cache is not needed for this improvement.

Sources: [Efficiency 3](02-efficiency.md#3-filtered-listings-copy-and-scan-the-complete-inventory).

## 21. Share Schema Compilation And Declare The Runner's Real Dependency

**Maintainability and interface clarity.** Four host-file/`fs.FS`,
direct/prepared paths repeat the schema compilation lifecycle. The runner also
declares a validator interface while requiring preparation through a runtime
assertion. Share the lifecycle behind source-specific adapters and make that
dependency explicit. Preserve malformed-output short-circuiting before schema
I/O, source containment, exact numbers, cancellation, and frozen plans. Retain
independent cross-source tests; do not force whole entry points to be identical.

Sources: [Complexity 1](03-complexity.md#1-consolidate-schema-compilation-and-express-the-runners-actual-interface),
[Equivalence 1](10-equivalence.md#1-share-the-schema-compilation-lifecycle-across-source-and-execution-paths).

## 22. Decompose Configuration Validation And Materialization

**Maintainability.** Large configuration operations mix record-specific
validation, resource capture, and effective-profile construction. Extract
focused helpers with visible inputs and ownership, rather than another generic
validation framework. Preserve final-handoff validation, presence/null rules,
origins, and meaningful fail-fast/error-precedence behavior. Do not turn
incidental ordering of independent validation failures into a new guarantee. The configuration-boundary ADR remains
authoritative; this is not a proposal to inspect raw ConfigKit sources.

Sources: [Complexity 2](03-complexity.md#2-decompose-configuration-validation-and-resource-materialization).

## 23. Clarify Requirement Traversal And Share Branch Orchestration

**Maintainability.** Separate recognition/evaluation from reachability and
evidence bookkeeping, particularly the repeated `if`/`with` branch protocol.
Keep their scope differences explicit and retain independent comparisons with
the actual Go renderer. Preserve conservative partial coverage and inactive
computed-name behavior. This does not justify a general template interpreter
or stronger execution-readiness promises from requirements inspection.

Sources: [Complexity 3](03-complexity.md#3-untangle-requirement-traversal-expression-evaluation-and-evidence),
[Equivalence 3](10-equivalence.md#3-share-ifwith-requirement-branch-orchestration-not-template-execution).

## 24. Centralize Compatible JSON Copying Without Conflating Policies

**Maintainability and ownership clarity.** The facade maintains a separate
reflection traversal for already-normalized values despite an existing
`internal/jsonvalue` owner. Consolidate genuinely compatible structural
copying while retaining DTO projection at the facade and distinct source
encoding/runtime validation policies. Preserve concrete types, nils, exact
numbers, schema keys, and ownership. Infallible projection must not acquire
new errors, panics, or silent zero-value fallbacks. Entries 3 and 5 remain
separate source-conversion defects, not reasons to reject pre-handoff sources.

Sources: [Complexity 4](03-complexity.md#4-clarify-ownership-and-policies-across-the-json-value-walkers),
[Equivalence 2](10-equivalence.md#2-centralize-structural-copying-of-already-normalized-json-values).

## 25. Separate Attempt Accounting From Generation Control Flow

**Maintainability.** Generation coordination interleaves dispatch/retry policy
with parallel return values and repeated evidence/observation projection.
Introduce a small attempt result and focused accounting helpers. Preserve
built-in versus injected-client differences, permit release before callbacks
or backoff, frozen requests, existing retry classification, private evidence,
and known/unknown usage distinctions. Do not collapse legitimately different
dispatch strategies merely to reduce lines.

Sources: [Complexity 5](03-complexity.md#5-extract-attempt-accounting-from-generation-control-flow).

## 26. Move OpenRouter Authentication Protocol Details Into Its Adapter

**Architectural ownership.** Use-case code currently interprets OpenRouter's
account-response fields and provider-relative endpoint while the outbound
adapter owns HTTP execution. Place protocol construction/recognition with the
outbound integration; keep diagnostic selection, applicability, cancellation,
completion, and neutral reporting in the use case. Preserve credential/body
privacy and anonymous probing. No plugin framework, reverse dependency, or
blanket prohibition on HTTP facts is needed. Coordinate the body-bound fix
in entry 2, which is a distinct behavioral change.

Sources: [Boundaries 2](11-boundaries.md#2-put-openrouter-authentication-protocol-details-behind-the-outbound-adapter).

## 27. Narrow Smoke-Value Copy Helpers To Real Consumers

**Ownership cleanup.** A request cloner has only its self-test as a caller;
the full-report cloner is used to detach only a target. Express that actual
copy operation directly and retire unused broader cloning after checking
callers. Keep facade request/report projection, active backend cloning,
provider-map errors, ownership tests, and redaction. Do not introduce shared
public/internal DTOs or an additional full-report copy.

Sources: [Boundaries 3](11-boundaries.md#3-narrow-smoke-value-copy-helpers-to-their-actual-ownership-boundaries).

## 28. Give Bundled Catalog Expectations One Test Owner

**Test duplication.** Complete bundled profile/model/provider expectations are
repeated across several test layers. Keep one independently specified asset
oracle, with smaller tests for distinct loading, wire, and diagnostic behavior.
Use controlled fixtures where bundled churn is irrelevant and structural
assertions rather than formatted-map strings. Retain meaningful bundled
coverage instead of deriving every expected value from the loader under test.

Sources: [Testing 7](08-testing.md#7-bundled-catalog-expectations-have-multiple-test-owners).

## 29. Stop Pinning The Opaque Artifact Hash Algorithm In Tests

**Over-specified tests.** Artifact tests and a benchmark assert a literal hash
algorithm despite the public value being opaque. Assert the documented
equality/ownership relationships and actual byte/size behavior instead; keep
benchmark setup outside its timed work. Coordinate with entry 31, but do not
turn today's hash representation into a new compatibility guarantee.

Sources: [Testing 6](08-testing.md#6-artifact-tests-and-benchmarks-pin-an-explicitly-opaque-hash-algorithm).

## 30. Remove Unconsumed Backend Presence Bookkeeping

**Low-priority state cleanup.** Backend field-state maps and
`QueueCapacitySet` have no runtime reader; effective values and ConfigKit
already own queue defaulting and provenance. Remove only these unused records
and adjust tests to assert effective behavior or operator inspection. Keep
profile/input presence tracking, explicit zero capacity, and derived defaults.

Sources: [Dead code 1](12-deadcode.md#1-remove-backend-presence-bookkeeping-with-no-runtime-consumer).

## 31. Retire Duplicate Fields In Captured Prompt Definitions

**Low-priority representation cleanup.** Captured definitions duplicate the
output format and carry an unused runtime message-file field after content
materialization. Use the captured output contract and text as their respective
sources of truth. Preserve real YAML `content_file` loading, origins, and the
request-override default rule. Removing serialized internal fields changes
current definition hashes: retain documented opaque equality relationships,
not an invented bit-identical encoding promise.

Sources: [Dead code 2](12-deadcode.md#2-retire-legacy-fields-in-the-captured-prompt-representation).

## 32. Remove Unused Private Diagnostic State And Helper Results

**Low-priority cleanup.** A private reachability outcome echoes an endpoint
that report assembly never reads; the schema-file helper returns a directory
that its only caller discards. Remove the unused state/result while preserving
actual sanitized request/report evidence, directory calculation, file checks,
and public single-file schema support. Keep privacy tests against the values
that real execution consumes.

Sources: [Dead code 3](12-deadcode.md#3-remove-unused-diagnostic-state-and-a-discarded-helper-result).

## 33. Remove Orphan Internal Helpers And Their Self-Tests

**Low-priority cleanup.** `filecatalog.RelativePath` and
`resourceNamespaceFromID` have only their own tests as callers, and the runner
test's `stringPtr` helper is entirely unused. Remove those narrow surfaces
without replacement, preserving real discovery, identity qualification, and
namespace inventory/filtering coverage. Reachability from examples alone is
not a reason to remove optional public APIs.

Sources: [Dead code 4](12-deadcode.md#4-remove-orphan-helpers-whose-only-callers-are-their-own-tests).

## 34. Decide Whether To Retain The Legacy Capacity Client Wrapper

**Decision-dependent architectural cleanup.** The old capacity client wrapper
is used by tests, whereas production dispatch uses the generation coordinator.
It is also explicitly retained in current internal documentation; the dead-code
audit does not classify it as obsolete functionality. If that retention decision
is revised, exercise the production coordinator in runner tests and move any
needed one-shot capacity scaffolding into tests before retiring the wrapper.
Preserve FIFO, cancellation, independent-pool, and panic-release coverage.
This is not a second scheduling algorithm or a confirmed concurrency defect.

Sources: [Boundaries 1](11-boundaries.md#1-retire-the-test-only-capacity-client-as-a-production-scheduling-surface),
[Dead-code retention qualification](12-deadcode.md#intentional-retention-and-related-findings).

## Open Decisions

Work through the decisions below in this order. These are unresolved choices,
not additional findings or approved changes to public contracts. A decision
blocks its dependent remediation, not unrelated fixes. In particular, updating
the maintainer toolchain need not wait for the consumer-minimum decision.
Implementation details and optional cleanup do not become release gates merely
by appearing in this catalog.

### Decision 1: ArtifactReader Result Ownership And Lifetime

**Related finding:** [4](#4-resolve-the-artifactreader-buffer-ownership-contract).

**Question:** What ownership does a successful `Read` transfer, and when may
an injected reader mutate or reuse the returned storage?

**Recommendation:** Transfer an independent result to PromptKit on successful
return. The reader must stop mutating the returned artifact and its body,
including through retained aliases. Fresh per-invocation storage is the simplest
implementation; immutable shared data can remain shared if no collaborator
mutates it. This removes the impossible immediate-reuse permission without
adding synchronization or a release protocol to the interface. Explain the
consumer impact as a deliberate pre-1.0 contract correction.

**Alternative:** Permit borrowing until the enclosing preparation/execution
operation returns. This can support application-managed reuse, but a reader
cannot generally observe that lifetime and concurrent calls need independent
storage or caller coordination. If reuse immediately after `Read` returns is
required, an explicit acknowledgement/release API is another viable design;
it enables pooling at the cost of a larger interface and lifecycle change.

**Resolve before implementation:** Select the ownership/lifetime rule and update
GoDoc, adapter assumptions, and the regression scenario together. Another
unsynchronized copy is not a remedy for the current permission.

### Decision 2: Provider Submission Of Multi-Resource Schemas

**Related findings:** [6](#6-make-provider-native-schema-constraints-self-contained)
and [21](#21-share-schema-compilation-and-declare-the-runners-real-dependency).

**Question:** How should native structured output represent a schema whose
local validation depends on external resources?

**Recommendation:** First investigate packaging the operation's captured
resource graph into a self-contained provider constraint. Check identifiers,
relative references, anchors, recursion, and supported dialects before choosing
an encoding. Prefer correct packaging when it fits a proportionate scope,
while keeping resource completeness distinct from any provider's supported
schema subset. A standalone offline validation of the actual emitted constraint
should establish the selected packaging behavior.

**Alternative:** Offer an explicit local-only validation choice when native
submission cannot represent the resource graph. This preserves useful local
validation and avoids building a general schema transformation system, but
forgoes native generation constraints for that selected mode and needs a clear
consumer-facing selection mechanism. Silently dropping native constraints is
not equivalent to an explicit choice.

**Resolve before implementation:** Establish packaging feasibility and select
the submission/fallback policy, including behavior for unsupported cases.
Coordinate the compilation refactor with that result; it does not itself fix
provider packaging or establish universal provider acceptance.

### Decision 3: Authentication Response Budget And Overflow Outcome

**Related findings:** [2](#2-bound-authentication-probe-response-consumption)
and [26](#26-move-openrouter-authentication-protocol-details-into-its-adapter).

**Question:** What finite response budget should the authentication adapter
apply, and how should a probe report exceeding it?

**Recommendation:** Select a conservative fixed budget for this small protocol,
check actual streamed bytes regardless of declared length, and close on overflow
without unbounded draining. Report the diagnostic failure with acceptance
unknown, retaining any independently observed HTTP facts. Agree the exact byte
count and its representation in the existing diagnostic report before coding;
the catalog does not select either implicitly.

**Alternative:** Expose a caller-configurable budget with a finite default.
This accommodates unusual legitimate responses but expands configuration and
validation surface. It is worthwhile if a concrete consumer requirement cannot
be served by an appropriately chosen fixed budget; it is not necessary merely
to address the demonstrated unbounded read.

**Resolve before implementation:** Choose the size, overflow classification,
and whether configurability is warranted. Keep this fix independent of adapter
relocation so architectural cleanup does not delay the resource remedy.

### Decision 4: Exact Numbers And The Source-Conversion Boundary

**Related findings:** [3](#3-avoid-exponential-expansion-during-convenience-source-conversion),
[5](#5-preserve-exact-numbers-in-programmatic-provider-sources), and
[24](#24-centralize-compatible-json-copying-without-conflating-policies).

**Question:** Which exact numeric values can the convenience helpers preserve
through the current ConfigKit mapping boundary, and what happens to others?

**Recommendation:** Preserve supported values through the complete conversion,
load, and outbound-encoding path; defer an unsupported-value error when exact
preservation is unavailable. Compare numeric meaning rather than spelling or
successful parsing alone. Address shared-graph expansion in the same adapter
with completed-conversion memoization, distinct cycle tracking, and correct
slice-view identity, preserving source capture and deferred failures.

**Alternative:** Request upstream support for additional exact numeric/value
forms, then simplify or remove the relevant PromptKit conversion. This may
provide a cleaner long-term boundary and broader preservation, but introduces
an upstream dependency and should not postpone fixing silent rounding or
exponential expansion. Runtime JSON copying remains a separate policy.

**Resolve before implementation:** Establish the supported numeric round-trip
cases and whether broader upstream support is needed now. Do not substitute
numeric-looking strings or introduce a second raw-source validation system.

### Decision 5: Consumer Go Minimum After The Toolchain Update

**Related finding:** [1](#1-update-the-audited-maintainer-toolchain-for-applicable-security-fixes).

**Question:** Should the security fixes also change PromptKit's declared minimum
consumer Go version?

**Recommendation:** Update the maintainer toolchain and repeat the focused
assessment promptly; initially keep the consumer minimum decision separate.
Advise affected consumers to rebuild with a patched toolchain. This recognizes
that PromptKit publishes source and that downstream build/transport choices
control the deployed exposure.

**Alternative:** Raise the declared minimum to the selected patched release.
This makes the supported floor clearer and steers module consumers toward the
fixed toolchain, but changes compatibility and does not repair already-built
applications. Assess it under the existing release policy rather than treating
it as an automatic consequence of the scanner output.

**Resolve before changing the minimum:** Confirm current advisory applicability,
select the patched version, and decide whether changing the supported consumer
floor is justified. No new recurring release gate is implied.

### Decision 6: Retention Of The Legacy Capacity Client Wrapper

**Related finding:** [34](#34-decide-whether-to-retain-the-legacy-capacity-client-wrapper).

**Question:** Does the wrapper still justify a production surface for its
currently documented test-focused purpose?

**Recommendation:** Retire the production wrapper after moving the runner's
integration test to the production generation coordinator. Keep direct manager
coverage and any useful one-shot scaffolding in tests. This reduces maintenance
and makes assembled scheduling tests reflect production while preserving the
actual FIFO, cancellation, independent-pool, and panic-release scenarios.

**Alternative:** Retain it if a concrete internal use justifies the small
adapter. This avoids test migration and preserves that convenient composition,
but keeps a second assembly surface to understand and maintain. Existing
self-tests alone do not establish a future production need.

**Resolve before removal:** Confirm the intended retention decision and test
ownership. This cleanup can be deferred without blocking the behavioral fixes;
it is not evidence of a second scheduler or a concurrency defect.
