User description

Summary

Performs the final S5-A/S5-B1/S5-B2/S5-B3 cross-contract consistency audit for the R-15 Secure Storage Contract, per the AUTONOMOUS TERMINAL-CONVERGENCE DIRECTIVE's closing requirement. All four documents were read in full (3,174 + 184 + 246 + 104 lines) and checked for mutual agreement across 21 points: installation scope, secure anchor, root publication, RootKeyRef, key epochs, crash recovery, AuthoritySnapshot lifetime, marker/catalog authority, ordinary write admission, DISCOVER barrier, migration inventory, foreign-protected sources, plaintext-IDB representations, canonical destination payloads, source evidence/value equivalence, atomic-write temporaries, credentials, asset pairs, GC/retention, fault vectors, and the Core/platform boundary.

Two mechanical citation-drift findings, both corrected:

R15-SECURE-STORAGE-CONTRACT.md §10.4.1 — the disposition-count paragraph still described atomic-write temporary files as "blocked pending S5-B1," directly contradicting the same section's own preceding paragraph, which already declares S5-B1 admitted for exactly this gap (surviving atomic-write-temporary reconciliation). Updated to reflect that this class is now reconciled via S5-B1's admitted mechanism.
docs/native/r15/CHUNKED-LARGE-OBJECT-ENVELOPE.md §6 — the write-path crash-recovery paragraph cited "S5-B1's existing mechanism (§5)" for reconciling an orphaned R-15 write's own staging chunk. S5-B1 §5 is explicitly scoped to legacy pre-R15 temp files discovered during migration inventory, and its own defined outcomes (e.g. "treat it as the record's LEGACY_PLAINTEXT source for migration purposes") don't fit an already-operational R-15 write's own ciphertext staging debris — there's no migration or plaintext involved in that scenario. The parent contract's own §9 step 11 / §9.2 fault-point row already covers exactly this case (ordinary-write stale staging, reconciled via its operation_id/target_generation suffix, §3's atomic-write-temporary row). Both mechanisms agree on the same fail-closed behavior (preserve, never silently promote), so this was a wrong citation, not a safety defect. Corrected to cite the actually-applicable mechanism.

Every other cross-reference and shared formula was verified byte-for-byte where load-bearing — source_value_digest's formula is identical in both the parent and S5-B1; the marker-body is_chunked/chunk_count field ordering matches S5-B3's claims exactly (appended after content_digest/record_schema, never shifting existing offsets); §6.3's nonce/AAD domain-separation wording matches S5-B3's claimed fix; §5.3.3's reader-algorithm steps 2/7 and §3's reclamation-eligibility extension match S5-B2's integration exactly; §9.2's fault-point quotes S5-B3 cites are verbatim-accurate; the disposition registry's arithmetic (5 + 3 + 28 + 1 = 37, matching §3's inventory) checks out; and every document's status header agrees (all four admitted, none implementation-ready, no document claims a stale draft/proposed state relative to another).

No substantive design inconsistency was found.

Recorded S5_TERMINAL_R15_DESIGN_ADMITTED_MERGED_POSTMERGE_GREEN = TRUE in the parent contract's status header, §21 (S5 admission decision), and the migration ledger's row 10.

Test plan

pnpm run lint — pass
pnpm run docs:check — pass
pnpm run ci:prepush — pass (classified DOCS_ONLY)
CI: full required + advisory suite green

This PR is documentation-only (3 files under docs/native/) — no implementation, no production authority switch, no change to any admitted S5-A/S5-B1/S5-B2/S5-B3 semantics beyond the two citation corrections above.

Summary by Sourcery

Complete the final R-15 S5 cross-contract audit and resolve the identified documentation inconsistencies without changing implementation or production authority.

Bug Fixes:

Correct the R-15 disposition registry and Gate 7 rules so atomic-write temporary files use explicit, deterministic per-instance resolution without weakening authority-switch blocking.
Correct chunked-write recovery guidance to distinguish current staging chunks from orphaned chunks belonging to superseded write attempts.

Enhancements:

Complete the cross-contract consistency audit across the R-15 parent contract and S5-A/S5-B1/S5-B2/S5-B3 documents, confirming their references, formulas, status, and shared semantics agree.

Documentation:

Record that the final audit is complete while keeping the R-15 design non-implementation-ready and the production authority switch disabled pending post-merge validation.

Summary by cubic

Completes the final S5-A/S5-B1/S5-B2/S5-B3 cross-contract consistency audit for the R-15 secure storage contract. The audit found and corrected five inconsistencies, including three substantive gaps; no further inconsistencies remain. Documentation-only change with no implementation or production authority switch.

Bug Fixes

Corrected §10.4.1's disposition registry so atomic-write temporary files are an explicit fourth REFUSE_AUTHORITY_SWITCH group with a per-instance resolution procedure, instead of a "blocked pending S5-B1" carve-out that contradicted the section's exhaustiveness claim.
Made Gate 7's blocking rule instance-aware so the atomic-write class's class-level entry no longer makes the rule permanently unsatisfiable; only unresolved instances block.
Gave each chunk's staging form an operation_id/target_generation suffix so recovery distinguishes a superseded attempt's orphaned chunks from the current write's, and updated CHUNKED-LARGE-OBJECT-ENVELOPE.md §6 to check that suffix and cite §9.2 instead of S5-B1's migration-time mechanism.

S5_TERMINAL remains NO in this PR; it's declared only in a follow-up commit once this merges and post-merge main CI is confirmed green.

^{Written for commit 0ebc4d6. Summary will update on new commits.}

CodeAnt-AI Description

Clarify R-15 recovery rules and complete the cross-contract consistency audit

What Changed

Chunked write recovery now identifies staging files by the active write's operation and generation, preventing orphaned chunks from superseded attempts from being adopted.
Clarified that ordinary R-15 staging debris follows the storage contract's stale-staging recovery rules, not the migration-only discovery process.
Classified atomic-write temporary files as an explicit refusal group with deterministic reconciliation, preserving ambiguous survivors and blocking authority changes until resolved.
Recorded completion of the four-document consistency audit while keeping implementation and the production authority switch disabled until post-merge validation.

Impact

✅ Safer recovery after interrupted chunked writes
✅ Fewer risks of adopting stale staged data
✅ Clearer authority-switch blocking for unresolved temporary files

The documentation records completion of the R-15 S5 consistency audit, adds atomic-write temporary-file dispositions, and qualifies chunk staging locators by operation and generation.

Changes

R-15 storage contract updates

Layer / File(s)	Summary
Audit status and findings `docs/native/CORE-MIGRATION-LEDGER.md`, `docs/native/R15-SECURE-STORAGE-CONTRACT.md`	The documents record the completed consistency audit while keeping implementation and terminal status pending.
Temporary-file disposition rules `docs/native/R15-SECURE-STORAGE-CONTRACT.md`	Atomic-write temporary files use `REFUSE_AUTHORITY_SWITCH` rules. The disposition registry now has four exhaustive groups covering 37 protected classes.
Operation-qualified chunk staging `docs/native/r15/CHUNKED-LARGE-OBJECT-ENVELOPE.md`	Chunk staging locators include `operation_id` and `target_generation`. Recovery rejects staging files from superseded attempts and treats them as stale R-15 debris.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk:🟡 Moderate · up to 38a2d

The new atomic-write temporary-file rules can permanently prevent the authority-switch gate from completing even after affected files are resolved. Clarify that the gate evaluates unresolved instances or define a post-reconciliation disposition before merge.

We've triggered an ultrareview automatically — This final audit flips the R-15 secure-storage design to terminal/admitted and rewrites crash-recovery citation semantics across cross-contract specs, so a missed inconsistency could misguide implementation and threaten data integrity — worth a deeper pass.. I'll post findings when complete.

An ultrareview is cubic's deepest review, catching hard-to-find bugs in the most critical PRs. It runs a longer, multi-pass analysis using cubic's most capable review models, and typically takes around 30 minutes. It consumes your team's reviewed-lines allowance at 3× the standard rate.

Automated ultrareviews are disabled by default. We triggered this run as part of your trial. Want cubic to do this for every high-risk PR? Enable auto-ultrareview in your settings.

Documentation updates correctly reflect completion of the S5 cross-contract consistency audit. The changes consistently update status flags across all affected documents, document the two mechanical citation-drift findings that were corrected, and maintain the accurate distinction that this is design admission only (S5_TERMINAL=YES) with no production implementation (IMPLEMENTATION_NOT_STARTED). No defects found.

You can now have the agent implement changes and create commits directly on your pull request's source branch. Simply comment with /q followed by your request in natural language to ask the agent to make changes.

…445) Performed the final S5-A/S5-B1/S5-B2/S5-B3 cross-contract consistency audit: read all four merged R-15 documents in full and verified mutual agreement across every cross-reference, shared formula, and status flag. Two mechanical citation-drift findings, both corrected here: - R15-SECURE-STORAGE-CONTRACT.md's §10.4.1 disposition-count paragraph still described atomic-write temporary files as "blocked pending S5-B1", contradicting the same section's own preceding paragraph declaring S5-B1 admitted for exactly this gap. - CHUNKED-LARGE-OBJECT-ENVELOPE.md's §6 crash-recovery paragraph cited S5-B1's migration-time discovery mechanism for reconciling an ordinary R-15 write's own orphaned staging chunk. S5-B1 §5 is scoped to legacy pre-R15 temp files found during migration inventory, and its own defined outcomes (e.g. "treat it as the record's LEGACY_PLAINTEXT source for migration purposes") don't fit an already-operational write's staging debris. The parent contract's own §9 step 11 / §9.2 fault-point row already covers this exact scenario; both paths agreed on the same fail-closed behavior, so this was a wrong citation, not a safety defect. No substantive design inconsistency was found. Recorded S5_TERMINAL_R15_DESIGN_ADMITTED_MERGED_POSTMERGE_GREEN = TRUE in the parent contract's header/§21 and the migration ledger's row 10.

* chore(release): bump version to v1.28.4 Patch release reconciling release-truth documentation with everything merged to main since v1.28.3 (62 commits / ~40 PRs, audited against live GitHub state, not assumed from commit subjects): - fix: PWA first-install unprompted reload (#585, PR #613) - fix: shared-origin service-worker cache-read isolation (#514, PR #612) - fix: Factory Reset could reboot into Settings instead of Welcome Portal (PR #592) - fix: preserve-first desktop corruption recovery (PR #542) and a distinct filesystem-I/O recovery action (PR #545) - fix: intentionally cleared project metadata no longer reappears (PR #546) - a11y: Welcome/Home dashboard WCAG AA contrast + reduced-motion cascade fix + default appearance preset change (#565, PR #609); ManuscriptEditor contrast (PR #560) - security: fflate ZIP64-parsing DoS override (PR #595); routine dependency floor bumps (PR #587, #561, #562, #594) - docs: R-15 secure desktop storage design contract admitted (PRs #564, #580, #581, #582, #584) — design only, no implementation yet - tests: visual regression testing repaired — baselines were directory listings, not the application (PR #610); IDB reset-quiescence hardening (PR #596); WelcomePortal E2E navigation made locale-independent (PR #590) Everything classified as pure internal/CI-governance churn (PR-size exception plumbing, dual-graph tooling, toolchain pins) is omitted from CHANGELOG.md as non-user-facing. Version bumped via the existing sync scripts (sync-tauri-version.mjs, sync-sw-version.mjs) across package.json, src-tauri/Cargo.toml, src-tauri/tauri.conf.json, src-tauri/Cargo.lock, AGENTS.md, and public/sw.js's APP_VERSION. CHANGELOG.md and README.md use the established release-candidate marker convention () so the dated entry and version badge are truthful before the v1.28.4 tag exists; both markers are removed in a follow-up post-release truth-sync once the tag and GitHub Release are published, matching the v1.28.2/v1.28.3 precedent. TODO.md's Current Sprint section was archived (its final "release cut remains open" bullet is now resolved — v1.28.2 and v1.28.3 both shipped) and replaced with the actual current sprint: this release cut followed by the R-15 desktop at-rest encryption priority program. AUDIT.md is intentionally not touched here — its release-gate entry requires real post-merge CI/CodeQL run evidence that doesn't exist until after this PR merges and the tag is cut, matching how every prior release's AUDIT.md entry was written (a follow-up commit, not part of the release-prep PR itself). * docs(release): correct premature done-marker on the v1.28.4 TODO item TODO.md's Current Sprint marked the release cut as done (checked 'v1.28.4' release cut, reconciling ... AUDIT.md truth ...) while this same PR's own Non-goals section correctly states AUDIT.md is not touched here, and while no tag, GitHub Release, or release artifacts exist yet. Corrected to in-progress language naming PR #615 directly and listing what actually remains pending (tag, release, artifacts, post-release AUDIT.md evidence). * docs(release): correct R-15 gate language and credit PR #596's real fix Two corrections from review, verified against live evidence before fixing: 1. TODO.md's Current Sprint claimed R-15 desktop at-rest encryption implementation was being prioritized now. docs/native/DESKTOP- MIGRATION-ROADMAP-REV3.md explicitly forbids pulling Wave 3/4 R-15 implementation ahead of unresolved Wave 2 authority prerequisites, and CORE-MIGRATION-LEDGER.md row 10 records S5_IMPLEMENTATION_READY=NO. Corrected to state R-15 design is complete but implementation stays gated behind the still-open Wave 2 prerequisite (ledger row 9: the project state-shape compatibility adapter), which is what this sprint's desktop-storage work actually is. 2. CHANGELOG.md listed PR #596 only as generic IDB test hardening under Tests. Verified against its actual diff: deleteDatabase() previously resolved on a genuine onerror or an onblocked event as if deletion succeeded, so wipeAllAppData() could report Factory Reset complete while a database was never actually deleted. onerror now rejects; onblocked waits for the connection to close before giving up. This is a real production data-integrity fix, not test hardening, and now has its own Fixed entry.
