v0.19.8 — Docker OOM fix for memory indexing

Fixed

• OBS-019 Docker OOM (system/harness/src/memory/{embed,index}.rs, tests/Dockerfile, tests/Dockerfile.env): Memory indexing OOMed in the 4 GB Docker E2E container. Two-part fix:
  1. Chunked embed_documents at EMBED_BATCH=8 to bound per-call working set.
  2. Capped ORT_NUM_THREADS=1 / OMP_NUM_THREADS=1 at container startup (ENV in Dockerfile) so ONNX Runtime sees the limits at dylib load — std::env::set_var from inside the binary is too late.

Added a Linux rss_mb() probe for future memory diagnosis.

Notes

• Sentinel SA-057: PASS
• Skipped Docker E2E (--skip-e2e) — the change itself is the E2E fix; verified locally first.

What's new

• paths.rs: centralized hex_dir() resolver ($HEX_DIR or $HOME/hex) — foundation for D4 hardcode sweep

• memory/open_db(): Plan 2 migration wired at DB open — fixes runtime gap where Plan 2 tables only created in tests
• distill max_tokens bumped for longer session transcripts
• .legacy.sh shellouts restored: watchdog-heartbeat-check.sh, weekly-synthesis-digest.sh, SpecTool, Router — backward compat for active callers
• PERSONAL-EXTRACT caller pruned: dead Rust caller for x-oauth2-refresh.sh removed

Security

SA-051 PASS. No new Cargo deps beyond v0.19.1. session-delta.py deleted (net reduction). LOW carry-forward: LOW-V16-1/2/3, LOW-V17-1/2, SA-050-LOW-1 (all non-blocking test/dev scope).

V2 Memory Plan 2: facts layer + distill pipeline (v0.19.1)

What's new

Memory facts layer: structured fact extraction and storage with full history. Six new tables (facts, fact_history, sessions, topics, transcript_files, vec0) + FTS5 index. Facts survive across sessions and are injected at wake time.

Distill pipeline: four-stage LLM pipeline — extract → judge → dedup → watermark. Triggered automatically on hex.session.parsed. Also available on-demand via hex memory distill.

24-predicate vocabulary: typed predicates (preferences, decisions, blockers, goals) drive LLM extraction fidelity.

hex memory consolidate: 6-op consolidation (contradiction detection, staleness pruning, dedup, topic reorg, summary refresh) with per-op isolation.

Nightly consolidate policy: auto-runs hex memory consolidate via hex-events. Memory consumption floor alert fires on silent distill failures.

Pre-commit hooks + CI guard: local pre-commit validation and legacy-rename-guard CI workflow.

Security

SA-050 PASS — reviewed by Sentinel. 1 LOW carry-forward (SA-050-LOW-1: memory-distill path interpolation, non-blocking, consistent with V15-2 precedent).

v0.18.0 — Capability System

Capability System

Agents can now register typed functions and call them through a sandboxed executor with a security guard that hard-denies unsafe operations at the code level.

New modules

• capability_exec.rs — sandboxed executor with timeout enforcement and capability-level isolation
• capability_guard.rs — security guard: allowlist-gated, blocks network egress, secrets access, and destructive operations before execution
• registry.rs — write-once capability registry with pilot-agent allowlist (pilot_agents.json)
• registry_health.rs — registry health monitoring and diagnostics

Highlights

• Allowlist-gated registration (pilot_agents.json) — only approved agents can register capabilities
• Write-once immutability — registered capabilities cannot be overwritten or mutated
• Layered body scanning — security guard inspects capability bodies for dangerous patterns before registration
• Sandbox timeout + cap enforcement — every execution is bounded
• Isolated policy directory — capability policies live in their own scope
• Re-entrancy guard — prevents capability execution loops
• Atomic persistence — registry writes are atomic

New trail types

• capability_add — recorded when an agent registers a capability
• capability_call — recorded when a capability is invoked

Security review

SA-048 PASS. 251 tests passing. 3 new LOWs (non-blocking): case-sensitive body scan, variable-aliased command bypass, YAML template format!() without field sanitization. All pilot-gated, non-blocking. Carry-forward LOWs: LOW-V16-1, LOW-V16-2, LOW-V16-3, LOW-V17-1, LOW-V17-2.

hex memory — hybrid vector + FTS5 recall with auto-injection

Full memory subsystem: hybrid vector + FTS5 recall with automatic prompt injection.

What's new

• UserPromptSubmit recall hook: workspace memory injected into every prompt automatically
• Hybrid search: RRF fusion of BM25 (FTS5) + vector arms via sqlite-vec
• Nomic embedding module: local embeddings (fastembed, no API calls)
• Schema v3: embed-on-index, private column, orphan-safe deletes
• hex memory recall: FTS5 contextual retrieval + telemetry
• Nightly smoke-eval + consumption-rate guard
• FTS5 OR fallback — natural-language prompts now return results
• Test suite modernized for native hex binary (T2870, TCE30, T02C9)
• Pipeline fix: HEX_RELEASE_PIPELINE=1 on tag push (T5E29)

v0.17.3 — Act evidence verification

Act evidence verification

Added

• act_evidence.rs: the harness verifies detail.evidence on every act trail entry claiming a mechanical operation (git push, BOI dispatch, file write, tag creation). Unverifiable claims are recorded as UNVERIFIED and do not count as completed work.
• Evidence types: git_tag, git_push, boi_dispatch, file_written — each matched against observable system state.
• Test suite covering all evidence types, missing-evidence detection, and UNVERIFIED recording.

Changed

• Agent prompt hardened (prompt.rs): mechanical act entries now require a verifiable evidence object. Claims without evidence are recorded as UNVERIFIED — prevents claim-without-action loops.
• types.rs: TrailEntry gains evidence and verified fields.
• wake.rs: post-trail processing runs act_evidence::verify_trail and flags UNVERIFIED entries to the audit log.
