Owner

Problem and motivation

This issue tracks continuous Phase 6 audit closure for crashd. Receive authorized crash events and mediate retained crash information through the crash-service IPC boundary.

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.

Coherent realm image service prerequisites — 18 September 2026: Signed 6ca0127f6a871dcec9635b92d20f3a198261146e selects the original shared wire/startup dependency graph. Direct Rust implementation bytes are unchanged. All 8 default, all-feature and separate production development/release configurations pass 12 unit tests per configuration, strict host/native Clippy and freestanding linking with fatal linker warnings. Formatting, private-item rustdoc and Markdown pass, with zero warnings. Original push/PR CI is under observation. Matching catalog adoption and real consumer VMs remain requirements; complete realm and full in-guest build acceptance remain open.

Tracking and rollout

Runtime consumer dependency alignment — 15 September 2026

Signed 06a60f7c4b81f6f46d210161075bd1814fe91974 aligns the existing dependency selections with the original signed runtime graph. This checkpoint changes Cargo selections and the roadmap; this repository's Rust implementation files are unchanged. Formatting, strict Clippy, private rustdoc and canonical documentation checks pass without warnings. Default/all-feature development/release tests pass 12 default / 12 all-feature tests. Independent production configurations also pass strict host/native Clippy and native builds: crashd-runtime: 12 development / 12 release tests, crashd-runtime-crash-reporting: 12 development / 12 release tests. There are 8 supported native builds in total. Push/review CI 57/58 passes with complete classified logs and no final warnings. The product catalog, product VM acceptance and guest build remain pending. Review: #2.

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: 410b63cd15b39a206d13a44cde051d39d4dec9d3; 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.

Coherent dependency checkpoint — 20 September 2026: signed/pushed commit 60d1ad61592dc907e968b433fb902ef964395f58 aligns original shared dependency pins with the explicit installer-rights contract. Only the manifest and roadmap change; local implementation, APIs and authority policy are unchanged. Four strict 12-unit configurations, four native builds with the maintained linker layout, host/native Clippy, formatting, private rustdoc and dependency checks pass without warnings. Original CI 61/62 passes with four complete hashed logs (58,302 bytes), zero warning candidates.

Full catalog equality and actual consumer-image validation remain required under Integration regression 68. The broader work remains tracked by phase completion, including native external Rust/LLVM/runtime rebuilding and both complete EriX-in-EriX generations. This dependency checkpoint does not close full lifecycle, frame or self-hosting acceptance.

Acknowledged terminal service dependencies — 21 September 2026: signed c3eacdfb82dae7c9fae73ddaf9402f3d98048bed selects the original shared libraries for repeated terminal observation, exact acknowledgement and final CPU measurements under Kernel design 20. Four strict 12-test development/release and default/all-feature configurations, warning-denied host/native builds with the maintained linker layout, host/native Clippy, private rustdoc, applicable doctests, formatting and dependency/Markdown checks pass. All authored code remains below 1,000 lines. Original CI 63, 64 passes; complete hashed logs total 58,344 bytes with zero warning candidates. Full service CPU/profiler VM acceptance and guest builds remain open in Phase 6 completion.
