# Audit remediation roadmap

Status: target and decisions finalized; the [implementation plan](implementation.md)
defines the sprint. No remediation is implemented by these documents.

Baseline: `d131999c7c474010a4814bb81601cd32920e6c83`. The
[catalog](audit/catalog.md) contains 27 distinct open findings, five P2 and 22 P3,
from seven audits. Its accepted decisions and the
[remediation analysis](audit/remediation-analysis.md) supply the scope and
rationale for this roadmap. The implementation is unchanged since the audited
state `db732e3a1de55c844f77870e1c6db683c2685d5d`; subsequent commits recorded
the review and decisions.

This roadmap owns the target, scope, and completion criteria. The implementation
plan owns ordered stages, dependencies, concrete changes, and verification steps.
The catalog owns finding status and accepted remediation decisions;
the original audit entries own detailed evidence. This is separate from the
older, completed [shared-reporting remediation](https://gitea.maximumdirect.net/eric/CommandKit/src/commit/264b82bd5759f052a3646d57828945a87b7586d3/docs/roadmap/remediation.md), whose findings
are not reopened here. Unselected capabilities in [future work](future.md)
remain outside this effort.

## Current baseline and targeted end state

CommandKit has three modules. Core owns declarations, routing, typed inputs,
completion, invocation reporting, and outcomes, with Cobra/pflag behind private
adapters. ckconfig exposes configuration inspection through application-supplied
scopes. ckprompt exposes PromptKit inspection, preparation, requirements, and
smoke testing and composes configuration inspection through ckconfig.
Applications retain loading, runtime construction, resources, and executable
lifecycle; upstream libraries retain domain semantics.

The current manifests select ConfigKit v1.1.0 and PromptKit v0.20.0. Both
integrations select core v0.4.0, and ckprompt selects ckconfig v0.4.0. The ignored
workspace can align the three local source modules. Core declares Go 1.26.0;
the integrations declare Go 1.27.0. This remediation selects no upstream upgrade
or consumer toolchain change.

The target keeps that architecture and existing command suite while delivering:

- Accurate outcomes and retained evidence when cancellation, provider mistakes,
  or presentation failures occur, and isolation of CommandKit-parsed JSON
  between the identified request destinations.
- An explicit deferred-message acceptance cutoff, release of unnecessary
  borrowed-writer references after finalization, and one implementation of
  shared detail-rendering bookkeeping.
- Working maintained examples and completion validation, with tests exercising
  current production paths instead of obsolete private entry points.
- Narrower provider responsibilities and shared ConfigKit diagnostic adaptation
  serving both integrations' CLI reporting.
- Shared internal flag-consumption mechanics, reuse of the existing alias tree,
  removal of avoidable repeated work, and bounded private extractions.
- Public documentation that accurately describes implemented provider and flag
  contracts, with current guidance separated from historical records.

CommandKit is pre-release with no consumers. Compatibility scaffolding and
consumer migration work are unnecessary for the selected API changes. This does
not alter the handling of published tags or historical release contents.

## Scope and implementation boundaries

Apply the [agent](../policy/agents.md), [architecture](../policy/architecture.md),
[testing](../policy/testing.md), and [documentation](../policy/documentation.md)
policies. The [CLI reference](../cli.md) and exported GoDoc remain the current
behavior owners; update them when their corresponding remedy lands.

The following limits keep the remedies within their accepted scope:

- F01 retains cancellation when it stops remaining smoke work; it does not make
  every cancellation after completed work a failure.
- F02 copies the known CLI JSON maps and arrays, preserving presence and numeric
  values. It does not promise arbitrary deep copies of application objects or
  repair application-created sharing.
- F03 closes deferred acceptance atomically when finalization begins, presents
  the accepted batch under existing visibility and failure rules, and rejects
  later deferred submissions with `ErrReporterClosed`. It does not promise
  successful delivery when rendering or writing fails, or require waiting for
  application producers or owning their goroutines.
- F04 rejects a missing prepared request in that command. Core can still render
  a legitimate null report. F05 keeps operation causes distinct from rendering
  and writing failures.
- F07 releases direct writer references after final presentation, without
  closing or flushing borrowed writers or promising immediate garbage collection.
  Retained errors may legitimately retain their own referenced objects.
- F10 documents the agreed current naming rules, including Unicode lowercase
  letters and digits, reserved names, and existing short spellings. It adds no
  ASCII-only or leading-letter restriction or automatic name normalization.
- F13–F15 are justified by the repeated-work analysis. Performance testing is
  not a prerequisite and no timing, allocation, or whole-installation complexity
  guarantee is introduced.
- F16–F20 remain internal simplifications. Keep meaningful caller differences,
  existing types, and necessary coordination; do not introduce a public parser,
  generic pipeline, replay framework, or new concurrency contract.
- F21 serves CLI presentation. It does not load or validate configuration,
  choose operation outcomes, or add general application-internal convenience
  interfaces. Core remains independent of ConfigKit and PromptKit.

Preserve native safe evidence, selected report content, error identity, explicit
presence, and the established independent comparison selections through these
changes. Do not replace upstream domain behavior or expand validation merely to
simplify implementation. Private helper names and exact signatures are ordinary
implementation choices unless explicitly selected as public API.

## Target capabilities and completion evidence

The areas below cover every catalog finding and define the desired end state,
without specifying implementation order. Each finding remains accountable for
its own remedy and evidence; a nearby refactor or passing broad suite alone does
not establish that a defect is fixed.

### Correct outcomes, request ownership, and reporting lifecycle

| Finding | Required work | Evidence of the intended result |
| --- | --- | --- |
| F01 | Retain cancellation at the aggregate smoke checkpoint that omits remaining kinds, preserving previous errors and completed reports. | Cancellation during progress delivery or between operations produces a failed partial outcome with the cancellation cause; prior errors survive and unattempted kinds receive no invented report. |
| F02 | Copy parsed extra-parameter objects and nested arrays/maps at binding application and each aggregate seed boundary. | Mutating one destination does not alter a later smoke request or an independent captured-binding application; empty/nil and numeric distinctions remain intact. |
| F03 | Make deferred acceptance closure and batch detachment atomic while retaining the finalizer's delivery path. Document the cutoff. | A controlled concurrent submission is either accepted for the final batch or rejected as closed; successful acceptance cannot disappear into an abandoned queue. |
| F04 | Reject nil prepared results returned without an error, after the existing acquisition/cancellation handling. | The prepared-preview command fails operationally and retains supplied diagnostics/explanation; valid previews and core null reports retain their existing treatment. |
| F05 | Carry buffered configuration-show cancellation separately from renderer errors. | Interrupted preparation emits no partial aggregate report, retains cancellation as the operation cause, and does not invent a rendering failure; genuine rendering/writing failures remain observable. |
| F07 | Clear direct destination references under the existing reporting lock after final presentation. | Closed handles still reject late operations, returned presentation evidence survives, and CommandKit no longer retains writers through those direct fields or closes them. |

F03 and F07 touch the same finalization boundary but fix different problems.
Keep them separately explainable. F20's bookkeeping extraction must not
be used as a substitute for either correction.

### Working examples and completion validation

| Finding | Required work | Evidence of the intended result |
| --- | --- | --- |
| F06 | Remove the completion fixture's collision with core's reserved `format` flag. Use core's flag when testing report selection, or rename the fixture's custom choice flag when testing application completion. Adjust corresponding expectations. | The fixture constructs and generates scripts, and available opt-in shell checks exercise completion rather than failing during installation. |
| F08 | Assign the example's optional scenario argument only when supplied. | Bare `report` runs its `demo` default; an explicitly supplied value still reaches ordinary validation. |

The existing completion harness remains the validation owner; its prerequisites
and commands belong to the [developer guide](../development.md#shell-completion-validation).
Unavailable shell checks remain distinct from successful checks. This does not
select a new platform support matrix.

### Clear and narrow integration boundaries

| Finding | Required work | Evidence of the intended result |
| --- | --- | --- |
| F09 | Document `EffectiveWriter` as supplying safe YAML for `DecodeYAMLReport`, link the conversion contract, and correct `View`'s report description. | GoDoc describes the actual single-document conversion boundary and does not imply native formatting passthrough or broader YAML support. |
| F10 | Document the accepted naming/reservation rules once in `FlagMeta`; link relevant rename and alias helpers. | Public guidance matches installation behavior without changing the validator or flag-value semantics. |
| F11 | Remove `WriteExplanation` from `ExplanationReader`; update GoDoc and obsolete stubs/assertions. | Custom explanation providers need only acquisition, and standard handlers continue rendering acquired evidence through core. Native objects may keep their own writer methods. |
| F21 | Expose one narrow ckconfig diagnostic adaptation function and use it in both integrations, replacing the duplicated adaptation. | Both callers retain the selected snapshots, severity treatment, source labels, ordering, and native formatting; command-specific context, causes, outcomes, and scheduling remain with callers. |
| F23 | Make concise-diff token decoding accept native `configkit.Path` and remove unreachable arbitrary-string validation. | Literal key tokens, including `~01`, empty keys, slash, tilde, and root paths, remain correct; snapshot failures and actual operator-input validation remain intact. |

For F21, the accepted input/output shape is a caller-supplied heading, native
source records, and native diagnostic records returning existing core diagnostics
and an explanation. The illustrative `AdaptDiagnostics` name in the analysis is
not a separate required spelling. Reuse the existing private helper's work;
keep the smaller scheduling switches with their callers. No new module is needed.

For F23, ConfigKit's opaque path is already valid, but the concise report still
needs key-token decoding. Remove revalidation, not that necessary translation.
Use bounded single-pass escape decoding so `~01` becomes `~1`, not `/`.

### Cohesive private responsibilities

| Finding | Required work | Evidence of the intended result |
| --- | --- | --- |
| F12 | Remove unused execution-resource fields and parser options and redundant normalization. Keep invocation resources with their real owners. | Parsing and buffered help retain their behavior without application input/context/streams threaded through unused backend fields; internal discard destinations still prevent accidental process output. |
| F24 | Move tests to real selection, finalization, routed parsing, and occurrence-aware preparation paths; remove obsolete production wrappers. | Useful assertions remain, superseded paths have no production test support burden, and any small setup helpers live in test files. |
| F16 | Share flag identity, attached/missing values, next-argument consumption, and short-cluster position through small neutral internal helpers. | Execution and completion agree on shared grammar while preserving entered spellings, explicit empty values, and their distinct treatment of unfinished input. |
| F20 | Extract common detail-rendering/error bookkeeping under the existing reporting lock. | Ordinary and terminal reporting retain distinct headings/visibility/timing while sharing rendering-versus-writing classification, callback order, and error retention. |
| F18 | Separate operation checks, scope/capability selection, and two-sided comparison preparation using private functions. | Help and preflight remain metadata/input-only where required; input checks precede state/acquisition, and comparison sides remain independent. |
| F17 | Separate cohesive scope capture/validation and selector attachment work; make operation bindings and discovery inventory construction explicit. | Captured ownership, retained errors, binding identity, discovery, and construction without provider acquisition remain intact. |
| F19 | Extract conversion-error attribution and operand preparation modestly, keeping flag preparation and occurrence ordering together. | Entered spelling, supplied-state distinctions, error identity, application order, and captured replay remain correct without replacing dense reconstruction or the existing merge algorithm. |

F24 covers all identified obsolete entry points. Extractions retain related
loops and existing prepared types; F19 remains conservative. Tests protect
behavior rather than helper counts, incidental private call sequences, or
complexity scores.

For F16, retain execution normalization and failure handling with the parser,
and partial-word handling and suggestions with completion. Keep caller-specific
branches where unification requires extensive modes or special cases. This
sharing introduces no new alias-completion behavior.

### Efficient alias and diagnostic-path traversal

| Finding | Required work | Evidence of the intended result |
| --- | --- | --- |
| F13 | Resolve each context's effective flag-alias graph with visitation states and memoized terminal results, including inactive endpoints. | Each shared suffix is resolved once per context; scoped precedence, canonical endpoints, missing-target handling, and cycle diagnostics retain their meaning. |
| F14 | Enumerate distinct nonempty proper source prefixes through the existing resolver tree and classify each once. | Shared prefixes avoid repeated construction/classification; canonical paths, exact aliases, and valid canonical operand space retain their exclusions. |
| F15 | Query strict descendant sources through that same tree for each existing intermediate resolution path. | Help avoids full-catalog scans for unrelated sources while preserving authoritative resolution, longer overrides, canonical-target checks, suffix deduplication, and output order. |
| F22 | Use a scratch path during declaration validation and format full paths only for emitted diagnostics. | Successful validation avoids eager full-path formatting, while retained issues, error identity, child order, and absent/root-only declaration handling remain correct. |

F14 and F15 share internal read-only operations on the existing resolver tree,
with private nodes, correctly owned captured paths, and the existing
routing-snapshot lifetime. Root help may still use the complete catalog when
all entries are needed. No second index, persistent result cache, new alias
limits, or alias-completion features are selected.

Source-level review should establish removal of the identified repeated work;
behavioral checks establish preserved results. No performance threshold or
benchmark suite is required to justify these remedies. Other routing,
termination-analysis, formatting, and installation costs remain outside those
specific complexity improvements.

### Consistent current guidance and historical navigation

| Finding | Required work | Evidence of the intended result |
| --- | --- | --- |
| F25 | Replace stale planning/status directions in reporting ADR 0006 with current GoDoc/CLI references, preserving its accepted decision. | The ADR no longer presents implemented reporting as a pending prerequisite; no replacement ADR is introduced for unchanged architecture. |
| F26 | Keep a brief module/status orientation in README and link the consumer guide for exact compatibility and installation details. | Volatile compatibility guidance has one canonical owner. |
| F27 | Add a useful forward-only correction identifying the correct pinned consumer-guide section for the historical ckprompt note. | The correction points to the actual section without modifying the published tag, historical note, or hosted release contents. |

GoDoc, CLI documentation, examples, and focused internal documentation must
describe the implemented boundaries, with valid links and semantic claims.
Existing audit evidence remains available; the catalog records each finding's
implementation/verification result. A selected remedy alone does not close it.

## Verification and module alignment

Verification establishes CommandKit's adaptation and coordination, without
independently testing upstream domain correctness or turning private mechanics
into public guarantees. Consequential defects have focused behavioral protection;
useful contract coverage survives deletion of obsolete test machinery. The
implementation plan defines proportionate checks and when to run them.

For F03, acceptance/finalization evidence must establish queue ordering; a race
detector alone cannot do so. F07 does not establish a garbage collection timing
promise. Ordinary suites remain deterministic, offline, and independent of
credentials or live model services.

The [developer guide](../development.md#documentation-validation) owns module and
workspace test commands. The root suite does not traverse nested modules.
Evidence covers combined local source, representative maintained consumers,
and available repaired completion checks using the already selected Go 1.27.0.

The independent-module check has a concrete dependency constraint: ckprompt's
new F21 call will not exist in its currently selected ckconfig v0.4.0 dependency.
Workspace success therefore cannot be reported as proof that unchanged
independent module requirements are ready. Preserve the ignored workspace files;
do not commit sibling replacements or fabricate dependency checksums.

During source development, record workspace evidence separately. Temporary
external-consumer modules or alternate module files with explicit local
replacements may provide additional boundary evidence, but are not validation
of the published dependency selection. Once the required CommandKit module
versions are available, align requirements/checksums and run each independent
module suite with the workspace disabled. Until then, report the independent
dependency limitation explicitly rather than marking that check complete.

The [release procedure](../release.md) owns dependency-order publication and
candidate validation. Release version selection, notes, and publication remain
separate work; this roadmap neither authorizes publication nor makes it a
prerequisite for source refactoring. When preparing a release, reuse that
procedure rather than inventing additional gates. The absence of consumers
removes migration work, not the need for coherent module requirements.

## Completion criteria

- [ ] Every finding F01–F27 has its selected remediation implemented and recorded
  with relevant evidence; related findings remain individually accountable.
- [ ] The five P2 defects have focused behavioral protection, including error
  identity, retained evidence, and the deferred acceptance boundary.
- [ ] F06 and F08's maintained consumers work, with actual completion checks
  distinguished from unavailable or skipped shell checks.
- [ ] F11 and F21's selected API changes and F09/F10's clarified contracts are
  reflected in canonical GoDoc and affected integration guidance.
- [ ] Obsolete production wrappers/plumbing and duplicate adaptation/bookkeeping
  are removed at the agreed boundaries, with useful tests retained.
- [ ] F13–F15 and F22 remove the identified repeated work while preserving
  behavior, without a new performance guarantee or measurement prerequisite.
- [ ] F17–F20 improve responsibility separation within their bounded scope;
  public behavior and necessary ordering remain protected.
- [ ] Documentation corrections F25–F27 are complete and local links resolve.
- [ ] Relevant module and aligned-workspace results are recorded. Independent
  results identify the exact dependency selection; any release-alignment work
  still pending is explicitly distinguished from completed source work.

The significant choices have been resolved in the catalog and remediation
analysis. Routine implementation details do not require an Open Decisions
section. Revisit a selected direction only if concrete implementation evidence
reveals a conflict or materially different tradeoff.
