Design decision + +The implementation architecture is approved for planning with one terminology correction: + +> **Verification Extension SDK** is the canonical v0.12 term. “Domain Verification SDK” may be used only when describing the original feedback that motivated it. + +This prevents DKF from becoming specialised while retaining the ability for any project to add rigorous domain-specific verification outside core.

Architecture review + +**Verdict: PASS** + +### 3.1 Canonical authority + +T04 implements the project-local State Engine area: + +- `events.jsonl` — canonical runtime history; +- `snapshot.json` — derived current-state view; +- `index.db` — disposable/rebuildable acceleration index; +- `schema.json` — State Engine schema/authority descriptor; +- `legacy-backup.json` — migration recovery bundle when legacy migration occurs. + +The snapshot and index can be reconstructed from canonical history. + +The index cannot authorize state changes or replace the event ledger. + +### 3.2 Portable index choice + +The current `index.db` implementation is a deterministic portable JSON-encoded acceleration artifact, not SQLite. + +This is deliberate for T04: DKF's public Node >=18 compatibility is preserved, no Node-22-only SQLite runtime dependency is introduced, and the index remains disposable. + +A later index adapter may use SQLite without changing canonical state authority. + +### 3.3 Generic entity model + +State Engine core understands generic entity type, entity ID, state revision, lifecycle/task/contract/run references, state patch operations, and generic metadata events. + +It contains no application or industry business-state semantics. + +Autopilot and orchestration formats are integration/migration adapters around the generic core. + +### 3.4 Event-backed state + +Initial entity state is stored once. + +Subsequent changes are represented as deterministic path-based set/delete operations rather than another full canonical snapshot file. + +Events carry monotonic sequence, deterministic event ID, timestamp, actor class, entity references, event type, payload, previous-event hash, and event hash. + +### 3.5 Crash/recovery model + +Canonical event writes use temporary file -> fsync -> atomic rename. + +A short State Engine lock prevents overlapping local commits. + +If failure occurs before canonical rename, the existing ledger remains authoritative. If failure occurs after ledger commit but before snapshot/index completion, derived state rebuilds from events. Orphan temporary files do not advance canonical state. + +## 4. Migration review + +**Verdict: PASS** + +Migration validates all detected supported legacy inputs before State Engine creation/cutover. + +Supported legacy inputs include Autopilot revision chains/current pointer and orchestration manifest/revisions/current pointer/final state where present. + +Migration then creates a fingerprinted recoverable backup bundle, imports validated history, reconstructs V2 current state, verifies semantic equivalence, appends `MIGRATION_COMPLETED` only after equivalence, and verifies State Engine integrity. + +Repeated execution is idempotent. Partial execution remains recoverable and does not trigger cutover. Legacy state is not deleted by T04. + +## 5. Acceptance-semantics review + +**Verdict: PASS** + +The orchestration migration fixture begins with `state=ACCEPTED`, `acceptanceState=ACCEPTED`, and `verificationVerdict=PASS`. + +After migration, V2 reproduces those same values. + +T04 changes persistence, not acceptance authority. + +## 6. Security review + +**Verdict: PASS** + +Reviewed threats include event mutation/insertion/reordering/deletion, canonical-tail loss, path escape, schema tampering, partial migration, corrupt legacy input, backup mismatch, index authority confusion, and premature cutover. + +Controls include monotonic sequence, chained SHA-256 hashes, snapshot sequence/hash integrity witness, exact schema contract, project-root realpath confinement, short write lock, atomic canonical replacement, derived-state rebuild, fail-closed legacy validation, fingerprinted recovery bundle, verified migration-completion cutover, and semantic-equivalence verification. + +Unresolved security findings: none. + +## 7. Security control-domain review + +**Verdict: PASS** + +State authority cannot move from legacy to V2 merely because V2 files or partially imported entities exist. + +The cutover condition is a completed migration record produced only after semantic-equivalence verification. + +Corrupt or incomplete source state blocks migration. Corrupt or tampered State Engine authority blocks reads/integrity verification instead of silently falling back. + +## 8. State micro-file result + +Representative Phase 1 legacy transition shape is 27 files: 26 revision snapshots plus one current pointer. + +T04 active canonical/recovery representation is 5 State Engine files: `events.jsonl`, `snapshot.json`, `index.db`, `schema.json`, and `legacy-backup.json`. + +Measured active canonical/recovery file-count reduction: + +**27 -> 5 = 81.48%** + +This exceeds the >=80% v0.12 engineering objective for transition-generated state micro-file count. + +### Recovery-retention caveat + +T04 deliberately retains all 27 legacy source files until a later explicitly governed cleanup/cutover decision. + +Therefore, during the recovery-retention window, physical disk file count is 27 retained legacy files + 5 State Engine files = 32 files. + +The 81.48% result describes the new active canonical/recovery state representation, not total temporary on-disk file count while recovery originals are retained. + +## 9.

final H20/H21 revalidation at branch checks) ## Corrected engineering risks - **AUD-05 — event storage:** Canonical events are now physically appended rather than rewriting all prior bytes. An fsynced pending-commit journal records the expected prefix hash and complete suffix before appending. Verified incomplete suffixes can be repaired; conflicting suffixes fail closed. On POSIX, relevant rename/unlink directory metadata is also fsynced. - **AUD-06 — multi-process coordination:** The project-local lock spans current-state reads, sequence allocation, event construction and write. Owners are recorded by PID and hostname. A live local lock is not stolen merely because it is aged; a provably dead local owner is recoverable. Remote/unknown ownership fails closed. This is not a distributed multi-host lock. -- **AUD-07 — backup restore:** Full destination preflight checks parent directories and final files, rejects symlinks and junctions, and uses exclusive/no-follow file opens where supported. Legacy backups and originals remain retained. -- **Additional protection:** Canonical State Engine internal files may not themselves be symlinks/nonregular files. Existing Autopilot same-revision transition behavior was preserved after an initial regression was corrected. +- **AUD-07 — backup restore:** Read-only target preflight rejects symlinks, junctions and multiply-linked files. Full restore is assembled in a private sibling staging directory, fingerprint-verified, then promoted by renaming the destination root. No restored content is opened through mutable pre-existing target parents or final hard links. Original target tree is moved aside and rolled back on a failed promotion where possible; retained legacy source and backups are never removed. +- **Additional protection:** Canonical State Engine internal files may not be symlinks, multiply-linked inodes or nonregular files. Lock reclamation is serialized under an exclusive .reclaim directory; a stopped process during reclamation can leave a guard that must be inspected before manual recovery. The pending journal is cleared only after snapshot and index have been reconstructed and fsynced; stale materialized views are replayed under the State Engine writer lock. Existing Autopilot same-revision transition behavior was preserved after an initial regression was corrected. ## Reproduction and verification -Thirteen new T04-H01..H13 regression tests pass on Ubuntu and Windows: physical append file identity, aged live lock, four-process/48-event contention, interrupted append recovery, restore directory and file symlinks, conflicting pending suffix, dead-owner recovery and canonical-file symlink rejection. +Twenty-one T04-H01..H21 regression cases verify on Ubuntu and Windows: physical append file identity, aged live lock, four-process/48-event contention, interrupted append recovery, restore directory and file symlinks, conflicting pending suffix, dead-owner recovery and canonical-file symlink rejection. Additional test-driven cases are **H10** (missing terminal newline), **H11** (stale-lock recheck race), **H12** (legitimate concurrent snapshot advance) and **H13** (hard-linked restore destination). The unfixed earlier heads failed as expected: CI runs `37963478049` (H10/H11) and `37963732490` (H12/H13).

Red test H23 recorded POSIX root 0755->0700 in 37967284714. +- Fixed canonical descriptor opening with O_NOFOLLOW where supported, lstat/fstat inode identity and nlink checks and binding to the observed pre-commit inode+size. Fixed restore promotion to preserve original root mode, timestamps and POSIX UID/GID (fails closed if ownership cannot be set). +- Total hardening tests now H01–H23; H14 Windows-only and H23 POSIX-only. Latest independent review and full CI remain mandatory for the final HEAD. Node filesystem APIs do not guarantee preservation of custom Windows ACLs; this requires explicit host-native verification. +- The stacked PR #70 remains unmerged and 0.11.2 remains published. Do not confuse successful GitHub Actions with a persisted DKF risk-3 acceptance verdict.

Explicit environment and trust boundary + +A backup restore changes an entire project directory, including its files and operating-system metadata. Node.js 18+ cannot guarantee descriptor-relative `openat2`/equivalent anti-swap semantics on every supported Windows and Unix filesystem. The framework must **not** claim that path validation, a random staging name, `0700` permissions, or `confirmOffline: true` defeats another malicious process running under the **same OS identity**. + +**Supported T04 restore mode:** an operator-initiated, offline maintenance session with exclusive control of the target project and its parent directory. The operator must stop DKF writers, processes with access to the directory, and any untrusted process sharing the OS account before invocation. Backup bytes are validated, but the local host, operator and offline execution identity are trusted. This is a deliberate environmental scope, **not** an automatic protection enforced by a boolean option. If exclusivity cannot be established, **do not invoke the restore**. Production runtime should remain on the existing canonical state, and no provider should invoke restore autonomously. + +The `confirmOffline: true` parameter is a mandatory explicit caller attestation, not proof of isolation. Missing confirmation fails closed before any restore mutation. The restore operation is *not* a security sandbox for attacker-controlled local filesystem writers. + +A future capability supporting actively hostile same-UID processes requires a separately reviewed process/OS security boundary and handle-relative filesystem APIs. That capability is excluded from the T04 public contract. + +## 2. Journaled promotion transaction + +- Validate the backup's source fingerprint and all destination relative paths before modifying the target tree. +- Assemble the candidate restore in a private sibling staging directory. Preserve the existing root's POSIX mode, ownership and timestamps when supported, without silently claiming Windows custom ACL preservation. +- Persist and fsync a deterministic sibling promotion journal before renaming directories. The journal includes the target path and transaction ID plus original and candidate directory device/inode witnesses serialized as decimal strings (Node BigInt to avoid unsafe-number rounding). +- Rename the original target to a transaction-specific displaced path; fsync the parent on POSIX. Rename the candidate into place, fsync the parent, then delete the journal and sync the parent. +- Cleanup a displaced old tree only after promotion is durably acknowledged. No retained original recovery bundle inside the new root is deleted by the migration itself. + +**Recovery:** If a crash interrupts promotion, new `restoreLegacyBackup` calls refuse to run while the journal exists. A trusted operator explicitly calls `recoverLegacyRestore({targetRoot, confirmOffline:true})`. Recovery verifies the exact same target, transaction name, and persisted inode witnesses; restores a displaced original if the target is absent; or acknowledges an already promoted candidate. Ambiguous, swapped or malformed states fail closed without guessing. + +## 3. State lock guard failure recovery + +Normal State Engine writers never discard an uncertain `state.lock.reclaim` guard. The guard contains local PID, hostname, unique owner token and creation timestamp. A guard can be left behind by a crash or host termination. + +`recoverAbandonedStateLock({rootDir, confirmOffline:true})` is an **offline operator action**. It requires an aged (at least 60 seconds) guard, checks the guard's local owner process is gone where owner metadata exists, checks any remaining local state lock owner is gone, and uses conservative directory cleanup. A live owner, malformed state or recent guard refuses recovery. The call cannot prove no unauthorized same-UID process exists; the offline boundary is mandatory. + +## 4. Compatibility and failure discipline + +- Node.js >=18; no OS-specific native module required for the scoped offline contract. +- Existing State Engine runtime operations remain available; migration cutover remains conditional on semantic-equivalence checks. +- Backup restoration now requires explicit `confirmOffline: true` — a safety-related API tightening for operator callers, not a silent fallback. +- Replays and restoration never publish partial snapshots or claim successful acceptance on a failed integrity witness. +- An inability to preserve required platform-specific ACLs is an operational blocker, not permission to misrepresent equivalence. +- No T04 change here authorizes a package release, pruning legacy state, or bypassing Design Authority and human approval gates. + +## 5. Verification and remaining decision + +Automated tests H24–H28 validate offline confirmation, journal recovery after an injected failure and a real child-process termination, and operator-recoverable orphan guards. Earlier H01–H23 cover ledger integrity, concurrent writers, symlinks/hardlinks, snapshot recovery and permission preservation. + +**Formal acceptance decision must record:** whether the explicitly narrower *trusted offline operator* boundary is acceptable to the product owner/security authority for the T04 legacy restore capability. Automated tests cannot confer that authorization; independent risk-3 review must confirm that the code matches this scope, no in-scope Critical/Major findings remain, and the deterministic DKF governance evidence is persisted.

For v0.12.0 the runtime boundary is an exclusively controlled trusted local workspace. The stronger attack case remains an explicitly unsupported risk; independent security review must confirm this boundary is accurately enforced and disclosed.
