Problem and motivation

This issue tracks continuous Phase 6 audit closure for dynlinkd. Validate admitted dynamic objects and prepare dependency, symbol and relocation plans for authorized process materialization.

An initial inventory is not a security or documentation closure claim. Evidence must follow each changed boundary through final heads, with priority security, reliability, then performance.

Proposed behavior and scope

Current inventory: 1 Cargo target (1 bin); manifests: Cargo.toml. Include explicit and automatically discovered targets, supported features and target-specific configurations.

Inventory every startup/runtime grant and authenticated peer, then success, denial, cancellation, failed transfer, restart and teardown. Trace callers and downstream providers so names, numeric identities and retained aliases never become implicit authority.

Authority, security and reliability

Maintain a finding register with public finding references, exact revisions, invariants, reproduction, owners, regression tests and closure evidence. Publish only non-sensitive status here; suspected vulnerabilities follow SECURITY.md. Each dimension below needs its own result and rationale; an absent daemon or current Rust target is not a blanket exemption.

Acceptance criteria

  • Record origin, recipient, object, operations, delegation ceiling, lifetime and aliases for each relevant capability or caller-supplied authority-bearing value.
  • Audit ambient discovery/selectors, cwd/PATH/environment, numeric identities, inherited routes and host fallbacks; require explicit authorized intake.
  • Account for residual authority after success, error, cancellation, timeout, restart, failed transfer and teardown, including fork/exec where implemented.
  • Remove unnecessary endpoints, broad rights, duplicate aliases, provider/admin grants and debug routes.
  • Exercise stale generations, replay, pending replies, forged descriptive identity and object/path resolution races at the owned boundary.
  • Prove independent cleanup attempts and caller-specific error precedence; quarantine or terminate when retained authority cannot be accounted for.
  • Review unsafe/FFI/parser/arithmetic/lifetime/lock/publication invariants and add adversarial coverage where practical.
  • Inventory obsolete APIs, wrappers, fallback/dead paths and duplicate validators with their maintained callers.
  • Migrate callers and delete deprecated contracts/shims in a coherent signed revision graph; reject retired input versions where relevant.
  • Classify each size/count/depth/time bound as ABI, hardware, explicit resource policy or accidental limitation.
  • Test beyond removed boundaries and at allocation/ABI limits while preserving exhaustion errors, denial-of-service controls and bounded waits.
  • Keep every tracked authored code/test/script/workflow file below 1000 physical lines through thematic refactoring.
  • Run the deterministic tracked-source size gate, covering executable fixtures/generators and excluding only genuine non-code data or external payloads.
  • Audit production/test feature and symbol separation, including this repository's effect on rootd test orchestration.
  • Supply changes affecting rootd semantic surface to the maintained same-toolchain baseline; record a justified component-specific applicability result.
  • Check bootstrap ownership and development/release authority parity at this repository's producer/consumer boundary.
  • Use maintained integration#3 profiler evidence before optimizing; preserve live access checks, ownership and success criteria.
  • Audit build/CI inputs, secret handling, private outputs, symlink containment, deletion, subprocess bounds, warnings and host dependencies.
  • meaningful public/private inline documentation, crate/target missing_docs enforcement without blanket allowances or hidden-API escapes, warning-denied private-item rustdoc and an undocumented-public-API negative gate.
  • Validation: Run cargo fmt --all -- --check, strict Clippy, unit/doctests and warning-denied builds/rustdoc for every owned crate/target under default and all valid feature, freestanding/host, SMP and profile combinations; test mutually exclusive combinations separately. Add focused VM regressions for runtime behavior and observe the older catalog and unit tests at the exact published heads.
  • Documentation: update applicable README/ARCHITECTURE/ROADMAP in meta's canonical format and affected technical-manual TeX/API references; keep README evergreen and shared governance byte-identical to meta.
  • Evidence: record exact source/dependency revisions, commands, configurations, real exit status, CI run URLs and results; repeat the audit on final heads and obtain independent review of security closures. No skipped/pending/predecessor result counts as a pass.

Alternatives and tradeoffs

Use cohesive local refactoring or a justified shared extraction only after identifying real common semantics and authority boundaries. Remove superseded paths after preserving maintained coverage. Profile before optimization; document unavoidable ABI/hardware limits and explicit quotas rather than weakening security for speed.

Tracking and rollout

  • Parent work: erix/integration#2 and erix/docs#1.
  • Branch: feature/posix-compat; update linked WIP PRs after coherent signed checkpoints using canonical CONTRIBUTING.md messages.
  • Baseline revision: c1d6502fad057d35915141157d0af2bf335a8c01; refresh component/dependency heads and their own CI evidence as implementation advances.
  • Cross-repository dependencies remain full lowercase commit hashes; update the selected graph deliberately. This issue does not authorize merges, release tags or replacement of published images.
