# Audit Remediation Roadmap
Status: target accepted; completed execution is recorded in the historical plan
at `bb5540b:docs/roadmap/implementation.md`.
Prepared: 2026-10-25. Planning baseline: `e1e94ee`.
This roadmap describes the target state and related work for the 29 entries
selected in the [consolidated audit review](https://gitea.maximumdirect.net/eric/ConfigKit/src/commit/453da684d7c7d3843a5f505f5c468b4c889dc6e2/docs/roadmap/audit.md#settled-scope-decisions).
It is intended for maintainers reviewing the remediation's scope and architecture.
## Document Ownership
- [Archived audit](https://gitea.maximumdirect.net/eric/ConfigKit/src/commit/453da684d7c7d3843a5f505f5c468b4c889dc6e2/docs/roadmap/audit.md) records finding IDs, original evidence, detailed remedies and
acceptance cases, and the settled scope decisions. Its evidence has not been
independently reproduced by writing this roadmap.
- This document owns the combined target state, work areas, and design intent.
Finding IDs below provide traceability without repeating the full audit inventory.
- The historical implementation plan at
`bb5540b:docs/roadmap/implementation.md` records concrete stages, private
implementation choices, edits, validation commands, and completion evidence.
The [configuration contract](../config.md), public Go declarations, and
[architecture policy](../policy/architecture.md) remain the owners of behavior
and guarantees. Update their applicable implementation documentation when work
lands; this planning document does not redefine their contracts.
## Current Baseline And Targeted End State
The existing loading model remains the foundation. Public loading APIs delegate
to the shared engine lifecycle; acquisition retains source scopes for composition,
then precedence, inheritance, decoding, CLI overrides, application resolution,
secret lookup, and validation produce a detached result with inspection metadata.
The [component overview](../internal/overview.md) describes the current owners.
The audits identify failures at particular traversal, lifetime, error, and
accounting boundaries, alongside redundant representations and repeated work.
The target is to repair those boundaries and simplify their implementation while
preserving ConfigKit's public API and configuration model.
| Current gap | Targeted outcome |
| --- | --- |
| Recursive descriptors can fail to terminate, failed dynamic builds can leave partial state, and slice aliases can be mistaken for cycles. | Traversal terminates for the reported cases, failed construction leaves reusable state valid, and supported acyclic values remain accepted. |
| Callback and owned-root cleanup can be skipped during panic unwinding; directory errors lose their failure phase. | Cleanup follows the lifetime of each owned resource, and selected-directory failures retain the information needed for correct error handling. |
| Finite symlink dependencies can be expanded repeatedly. | Completed dependencies are reused within a resolution while active cycles remain detectable. |
| Projection reservations and published history can escape existing accounting. | Existing budgets govern the relevant allocations and complete retained document graph. |
| Collection-policy work repeatedly scans or copies unrelated state. | Policy preparation, application, and retained evidence have clear ownership, with work localized to affected policy. |
| Acquisition has redundant paths and difficult handoffs; several private representations have no production consumer. | Production paths and their tests share the active protocol, with cohesive handoffs and unused representations removed. |
| Some lookups repeat full scans, and some tests assert incidental representation or miss meaningful mutations. | Local indexing avoids the identified repeated work, and tests protect observable contracts at useful boundaries. |
This is a bounded remediation effort, not a redesign of configuration semantics.
Correcting erroneous acceptance, rejection, cleanup, or diagnostics in the
reported cases restores existing contracts. It does not select new loading APIs,
configuration options, limits, background work, or persistent caches.
## Selected Work
The following areas account for all 29 selected entries. Detailed examples and
acceptance cases remain with their linked audit group.
### 1. Safe Typed-Value Traversal And Descriptor Reuse
Selected entries: **A01, A02, A03, A04, A05** in
[schema and typed values](https://gitea.maximumdirect.net/eric/ConfigKit/src/commit/453da684d7c7d3843a5f505f5c468b4c889dc6e2/docs/roadmap/audit.md#a-schema-and-typed-values).
Make pointer-only descriptor traversal terminate in decoding and path resolution,
while preserving supported null values and ordinary recursive structures. Make
dynamic descriptor construction transactional: a failed build must not leave
partial descriptors available to subsequent operations. Staging successful
additions or rolling back the complete failed addition set are implementation
choices; both must handle recursive references and preserve prior valid entries.
Correct active-path cycle detection to distinguish finite slice views sharing
storage from actual cycles. Keep detachment and nil/empty behavior intact across
the callers that share this traversal machinery.
Enforce existing projection budgets before large container reservations. Include
map-key materialization and overflow-safe lower-bound checks in the review; a
check after the reservation does not address the reported failure. This work
does not introduce a general heap limit or reject large containers independently
of existing budgets.
Dynamic-type eligibility reuse depends on safe descriptor construction and retains
completed successful checks within the value operation. Keep failure diagnostics
specific to their current path and distinguish completed results from traversal visits.
This removes repeated descriptor-graph walks without a cross-load cache.
### 2. Callback, Filesystem, And Dependency Lifetimes
Selected entries: **B01, B02** in [callback lifetime](https://gitea.maximumdirect.net/eric/ConfigKit/src/commit/453da684d7c7d3843a5f505f5c468b4c889dc6e2/docs/roadmap/audit.md#b-callback-and-filesystem-lifetime)
and **C01, C02** in [filesystem traversal](https://gitea.maximumdirect.net/eric/ConfigKit/src/commit/453da684d7c7d3843a5f505f5c468b4c889dc6e2/docs/roadmap/audit.md#c-import-selection-and-link-resolution).
Tie callback-context deactivation to the callback invocation with deferred cleanup
so it runs on normal return and panic unwinding. Independently give the owned
import root a deferred cleanup fallback. Preserve normal close-error handling,
caller ownership, and propagation of the original callback panic. Fixing either
state lifetime or handle lifetime does not fix the other.
Preserve the phase of a directory failure. A genuinely absent directory before
successful opening remains subject to existing permissiveness rules; a later
read or close failure must not be treated as absence. Apply this distinction to
both supported directory-reading paths. Strengthen the shared filesystem tests
to check each handle's closure and structured, non-disclosing diagnostics,
including partial reads and failures masked by another successful directory.
Do not change regular-file close-error policy as a side effect.
Avoid repeatedly expanding completed finite symlink dependencies in both host
and native filesystem resolution. Use operation-local memoization of completed
targets, or an equivalent dependency evaluation, with keys that respect the
resolution namespace. Keep active-path cycle detection separate from completed
work. Preserve containment, supported finite reuse, and existing host-path
semantics. The fix must work for directory and glob selection without a new
arbitrary traversal cap or changed symlink defaults.
### 3. Retained History And Combination Evidence
Selected entries: **D01, D02, D03, D04** in
[history and retained state](https://gitea.maximumdirect.net/eric/ConfigKit/src/commit/453da684d7c7d3843a5f505f5c468b4c889dc6e2/docs/roadmap/audit.md#d-retained-history-and-unused-evidence).
Remove the unconsumed override-result pre-CLI copy and the unqueried published
structural-input copy. Preserve the separate pre-CLI state used by active replay
and the structural input still used before publication for metadata and secret
classification. Remove unused combination-evidence members and the work needed
solely to produce them, retaining projections, mappings, origins, and snapshots
that have active consumers.
With retained roots clarified, enforce the existing history allowance against
the complete graph published through inspection, including replay and inheritance
state and publication-created copies. Count shared nodes once by pointer identity;
distinct retained copies still consume the allowance. Account for required copies
before creating them where practical. Removing an unused tree alone does not
resolve the accounting omissions.
Keep required before/after evidence and existing inspection behavior. Validate
the complete publication path with small controlled allowances, including the
interaction of CLI, resolution replay, and inheritance, rather than relying only
on tests of an isolated counting helper.
### 4. Collection-Policy Preparation And Application
Selected entries: **E01, E02, E03** in
[collection policy and projection](https://gitea.maximumdirect.net/eric/ConfigKit/src/commit/453da684d7c7d3843a5f505f5c468b4c889dc6e2/docs/roadmap/audit.md#e-collection-processing-and-efficiency).
Distinguish the existing policy state used for lookup, changes introduced by an
incoming tier, and evidence retained by the assembly. Prepare incoming claims and
declarations against read-only lower state, then apply the owned changes at the
appropriate combination boundary. Avoid copying every unrelated policy for
small tiers and scanning all policies for each independent replacement.
Use a semantic-path index, localized updates, or equivalent bounded lookup to
find affected policy. Preserve retirement timing, policy established by the
incoming contribution, pending declarations, persistent explicit modes, and
nested record ownership. Copying remains appropriate wherever mutable ownership
requires it. Removing only one duplicate clone or shortening a function does not
address the identified growth patterns.
Clarify preparation, evidence application, and finalization responsibilities.
Share straightforward history-descriptor translation where useful; evaluate
shared record-selection logic while keeping overlay and inheritance origin and
mode lifetimes distinct. Retain the common sequence-combination owner. This work
does not call for a generic merging framework.
### 5. Active Acquisition Handoffs And Private Cleanup
Selected entries: **F01, F02, F03, F04, F05, F06** in
[acquisition, cleanup, and test quality](https://gitea.maximumdirect.net/eric/ConfigKit/src/commit/453da684d7c7d3843a5f505f5c468b4c889dc6e2/docs/roadmap/audit.md#f-remaining-maintenance-and-test-improvements).
Remove the test-only eager acquisition mode so acquisition retains scopes through
the active production protocol. Tests that need composition should invoke the
actual composition boundary explicitly. Retire the parallel test-only import
parser and route relevant fixtures through the active directive parser or the
appropriate declaration boundary, retaining malformed-input coverage.
Clarify active acquisition and coordinator handoffs around cohesive tasks:
parsed-input directive/version handling, standalone placement, and repeated tier
application/projection. Use explicit inputs and results consistent with existing
state owners. Extracting helpers that continue to share surrounding mutable state
does not establish a clearer handoff. Preserve ordinary/layered differences,
overlay and diff behavior, source identity, callback timing, diagnostics, and
accounting scopes.
Remove the disconnected root record-clone family, uncalled engine helpers, and
unread private transport/result members identified in the audit. Reconfirm
references on the implementation baseline, including function values and relevant
build configurations. Preserve live conversion paths and validation side effects;
the audit's absence of field reads is not a general rule for deleting state.
Replace meaningful ownership coverage through the public boundary before removing
tests that only exercise disconnected helpers.
### 6. Local Lookup Improvements
Selected entries: **E04, E05** in
[collection policy and projection](https://gitea.maximumdirect.net/eric/ConfigKit/src/commit/453da684d7c7d3843a5f505f5c468b4c889dc6e2/docs/roadmap/audit.md#e-collection-processing-and-efficiency)
and **F08** in [secret-failure lookup](https://gitea.maximumdirect.net/eric/ConfigKit/src/commit/453da684d7c7d3843a5f505f5c468b4c889dc6e2/docs/roadmap/audit.md#f08-index-secret-failure-location-queries-lazily).
Reuse a local document lookup or equivalent traversal for tier-history projection
instead of rescanning wide mappings for each sequence. Preserve authored
coordinates, sparse projections, and evidence ownership.
Restore compound identity fields using indexed mapping positions and membership
checks rather than rescanning child and merged mappings for every field. Preserve
child-authored values and locations, mapping order, and detached nodes.
Build secret-failure location lookup state lazily when failures need it. Preserve
all diagnostics, nearest-location fallbacks, and confidentiality; successful
loads should not incur an unnecessary index merely to support failure reporting.
These changes address specific repeated work and do not promise a measured
startup improvement.
### 7. Tests That Protect The Intended Behavior
Selected entries: **F09, F10, F11, F12** in
[acquisition, cleanup, and test quality](https://gitea.maximumdirect.net/eric/ConfigKit/src/commit/453da684d7c7d3843a5f505f5c468b4c889dc6e2/docs/roadmap/audit.md#f-remaining-maintenance-and-test-improvements),
in addition to the regression coverage attached to each reported defect.
Cover historical-path enumeration through the public API, including removed
paths, queryability, ordering, and detached returned slices. Use those assertions
to replace private representation checks where they address the same risk.
Strengthen fuzz detachment checks by mutating existing descendants or in-length
elements, so spare capacity cannot hide aliases. Replace exact filesystem stat
call sequences with observable candidate ordering and meaningful failure
selection, retaining relevant assertions such as not opening excluded inputs.
Consolidate facade scaffolding around public construction, loading, errors,
ownership, and lifecycle behavior. Preserve distinct integration risks and
reader-byte snapshot coverage. Existing coverage percentages or a desired test
count are not acceptance criteria for this work.
## Implementation Plan
The historical implementation plan at `bb5540b:docs/roadmap/implementation.md`
defines the sequential, Luna-scoped stages and their dependencies, including
coordinated changes to descriptor state, history ownership/accounting, collection
policy, acquisition, and replacement public coverage. It also records validation
commands and the complete finding-to-stage map. The audit remains the owner of
original evidence and detailed acceptance cases.
## Validation And Completion
Validation follows the audit's detailed acceptance cases and the
[testing policy](../policy/testing.md). For fatal or hanging regressions, use bounded
subprocesses; for budget cases, use small controlled limits. For symlink expansion
and repeated lookup work, prefer bounded operation evidence and algorithm review
over timing thresholds. Use real filesystem fixtures where filesystem semantics
matter and narrow fault injection for read/close failures. State platform limits.
Applicable development checks come from the [development guide](../development.md),
including appropriate race coverage for changed ownership and lifetime boundaries.
The historical implementation plan owns their execution. Existing audit results
are baseline evidence, not validation of the eventual changes. No performance
benchmark campaign is required by this roadmap, and no new benchmark results are
claimed.
Completion means all 29 selected findings have implementation and acceptance
evidence, the affected public behavior remains consistent with its contracts,
and canonical internal documentation describes the resulting owners. The
historical implementation plan records execution status without duplicate
progress inventories. Retire completed planning records under the normal
documentation lifecycle.
## Scope Boundaries And Decision Status
All three audit scope questions are settled. No significant architectural or
product decision remains open for this roadmap. The historical implementation
plan records private design choices and sequencing, subject to the acceptance
cases above.
If that work exposes a need to change a public contract, bring the specific
decision back for review rather than treating it as an implicit part of remediation.
The glob preparation refactor (C03) and wider facade transport simplification
(F07) have since been selected in the
[internal-boundary roadmap](internal-boundaries.md). Other deferred features,
clone-traversal redesign, and broader performance experiments remain outside
this effort. Keep
existing ownership boundaries and loading APIs; no ADR or architecture-policy
change is proposed by this roadmap.
