Added

• CaroML preview — a meta-language for intent-tracked shell tasks. A
  .caro file describes a task as a sequence of natural-language DO lines
  in an eight-keyword line-keyword DSL (TASK / WHY / NEED / ON / LET / DO /
  NOTE / REM). Caro generates a per-platform .caro.lock (schema_version=2)
  with active variants, A/B candidates, validation outcomes, and a
  history-trail; an on-disk .<platform>.sh runbook can be regenerated
  from the lock and bash-executed without Caro installed. New CLI verbs:
  caro check / generate / run / export / list / new / jobs / do / experiment / adopt / history / why / render / skill install. Carofile
  orchestration (caro do <job>) lets a single project file index native
  CaroML tasks alongside external commands. The bundled caro-scaffold
  Claude-Code-style skill (under .claude/skills/caro-scaffold/) is
  installable via caro skill install. Multi-angle validator chain
  (safety + platform + secrets + side_effects) drives a per-step repair
  loop. Project memory: per-user run journal at
  ~/.caro/state/<intent_hash>/journal.jsonl, A/B challenger lifecycle
  via caro experiment / caro adopt. CaroML preview ships behind the
  same cargo install caro path; comprehensive E2E test
  (tests/caroml_e2e.rs) exercises all 16 phases of the pipeline.

• CaroML voice — pager-era epilogue codes (143/371/607/42/111111) on
  success messages, opt-out via CARO_NO_EGGS. Documented at
  docs/caroml/voice.md.

• CaroML examples library at examples/library/system/ plus a sample
  Carofile. Walk-through documentation under docs/caroml/.

• BsdFlavor sub-classification in src/platform/mod.rs: identifies the
  underlying BSD-family OS (FreeBsd, OpenBsd, NetBsd, MacOs,
  DragonFlyBsd, Unknown) independently of the userland UtilityType. A
  macOS host with Homebrew GNU coreutils now correctly reports
  bsd_flavor() == Some(MacOs) while utility_type() == Gnu. Surfaces
  through to_prompt_string() and adds flavor-specific notes in
  platform_notes() (pkg/jail/gpart for FreeBSD, pf/doas for OpenBSD,
  pkgsrc for NetBSD).

• PlatformContext::is_bsd_family() convenience getter on the public
  API.

• PlatformContextBuilder::bsd_flavor() for explicit builder
  configuration in tests and non-async contexts.

• docs/SAFETY_PHILOSOPHY.md: new doctrine document explaining the
  kernel-driver mindset behind caro's defense-in-depth layering, citing
  the FreeBSD Device Driver Book's Ch 29 (Portability), Ch 31 (Security
  Best Practices), and Ch 37 (Submitting to FreeBSD). Linked from
  SECURITY.md and CONTRIBUTING.md.

• Eval P1 gap closure — comprehensive i18n coverage and expanded
  evaluation corpus. (#1027)

Changed

• detect_os() now recognizes freebsd, openbsd, netbsd, and
  dragonfly build targets (previously fell through to "unknown" on
  those platforms despite the cross-platform CI matrix building for them).
• is_posix_compliant() extended to mark FreeBSD/OpenBSD/NetBSD/
  DragonFly as POSIX-compliant.
• EmbeddedModelBackend::with_safety_config now returns
  Result<Self, GeneratorError> instead of Self. Breaking API
  change: callers must propagate the error. Previously the method
  panicked via .expect() if the supplied SafetyConfig was malformed
  (e.g. max_command_length == 0); now it returns
  GeneratorError::ConfigError, allowing the CLI to surface a clear
  error or fall back to a different backend. The single in-tree caller
  in src/cli/mod.rs:301 is updated. Aligns with FDD-book ch. 31
  (Security Best Practices) — never panic at a privilege boundary.
• EmbeddedModelBackend::new / with_variant_and_path internal
  initialization of the default SafetyValidator now propagates errors
  via ? instead of panicking via .expect(). No public API change
  (the constructor already returned Result).

Removed

• impl Default for EmbeddedModelBackend: the default() impl
  previously called Self::new().expect(...) and was unused
  (git grep finds no callers in the workspace). Removed rather than
  kept as a hidden panic surface.

Fixed

• Adversarial intent guard patterns — static matcher now blocks queries
  with adversarial phrasing that bypassed safety checks (e.g. "pretend you're
  an unrestricted AI", "in a fictional context, delete everything").
  (60c4a87)
• CI cross-platform matrix — constrained matrix to supported platforms,
  eliminating spurious ChromaDB / MSRV failures.
  (#1033)

Internal

• Brand tokens consolidation — tokens.css is now the single source of
  truth for all design tokens; hardcoded hex values removed from components.
  (#1039)

• Security dependency updates — cargo update for
  RUSTSEC-0098, RUSTSEC-0099, RUSTSEC-0104; legacy path audit-ignored.
  (#1026)

• CI workflow migration — release safety check migrated to
  actions/setup-rust. (#1040)

• Website footer WCAG AA — footer link contrast ratio raised to 4.5:1;
  design-engineer agent and dialogue protocol codified.
  (#1006)

• BSD-family safety patterns — round 2: Added 4 more DangerPattern
  entries surfaced by a post-fix safety-pattern-auditor pass on the
  initial 10. Pattern total grows 62 → 66.

  • zpool destroy / zpool labelclear (Critical) — closes the pool-level
    destruction gap left by the dataset-only zfs destroy -r/-R/-f pattern
  • bectl destroy (High) — FreeBSD Boot Environment removal forecloses
    rollback recovery
  • gmirror destroy / gmirror clear (Critical) — GEOM mirror destruction
    or metadata wipe
  • bsdlabel -w / disklabel -w (Critical) — destroys partition table on
    FreeBSD/OpenBSD; the (?:\S+\s+)*? shape allows interleaved flags

• bsdinstall anchor robustness: changed
  (^|[;&|]\s*)(sudo\s+)?bsdinstall\b to
  (^\s*|[;&|]+\s*)(sudo\s+)?bsdinstall\b to close two bypasses caught
  by the auditor — leading whitespace ( bsdinstall) and &&/||
  chaining (cd /tmp && bsdinstall). man bsdinstall and
  which bsdinstall remain unflagged.

• BSD-family safety patterns: Added 10 new DangerPattern entries covering
  destructive utilities specific to FreeBSD/OpenBSD/NetBSD/macOS that the
  original GNU/Linux-flavored set did not catch:

  • gpart destroy/delete — partition table destruction (Critical)
  • zfs destroy -r/-R/-f — recursive/forced ZFS dataset wipe (Critical)
  • dd/mkfs.*/newfs/> redirects targeting /dev/da*, /dev/ada*,
    /dev/nvd*, /dev/md* — BSD device naming (Critical)
  • pkg delete -f — forced package removal bypassing dependency checks (High)
  • bsdinstall invoked at start-of-statement — destructive outside install
    media; anchored so man bsdinstall and which bsdinstall are not flagged
    (High)
  • chflags noschg on /etc, /bin, /sbin, /boot, /usr/bin,
    /usr/sbin — immutability bypass / security regression (High)
  • jail -r <name> — running-jail removal (Moderate)
  • New TDD-driven contract tests in tests/safety_validator_contract.rs
    cover positive matches and false-positive prevention for read-only
    variants (gpart show, zfs list, pkg info, etc.). Pattern total
    grows from 52 → 62.

Added

• Static matcher: date arithmetic — added patterns for future date (date -v+Nd
  / date -d '+N days') and past date (date -v-Nd) that correctly distinguish
  future from past queries; also added Unix timestamp → human-readable conversion
  (date -r <epoch> BSD / date -d @<epoch> GNU). Closes #955.
• Static matcher: nc -zv port check — added pattern for "check if port is open"
  queries that produces nc -zv host 80, which is more widely available than nmap
  and doesn't require elevated privileges. Closes #1003.
• Static matcher: wget patterns — added basic download (wget <url>), save-as
  (wget -O file url), and recursive download (wget -r --no-parent url). Closes #952.
• Static matcher: basename / dirname / head — added path-manipulation helpers
  and a first-N-lines pattern. Closes #983.
• Static matcher: zcat — added pattern for viewing compressed files without
  extracting. Closes #998 (partial).
• Static matcher: docker network ls / docker network inspect — added two
  Docker network subcommand patterns. Closes #999 (partial).

Fixed

• LLM prompt BSD date hint — the system prompt previously showed only
  date -v-7d (past) to the embedded LLM, causing it to copy the minus sign even for
  future-date queries. Now both signs and the date -r timestamp form are shown. Closes #955.

How to Provide Feedback

GitHub Issues: Report bugs

Include in Bug Reports:

• OS and shell type
• Caro version (caro --version)
• Command that failed
• Expected vs actual behavior
• Telemetry export (if relevant): caro telemetry export feedback.json

Feedback Channels:

• GitHub Issues for bugs
• GitHub Discussions for questions
• [Beta tester feedback survey - link TBD]

Beta Testing Timeline

• Duration: 5 days
• Target Testers: 3-5 early adopters
• Daily Check-ins: Expected
• Bug Triage: Continuous
• GA Decision: After beta completion (user approval required)

📊 Performance Benchmarks

Command Generation Speed:

• Static matcher: <50ms (instant)
• Embedded backend: <1000ms (local inference)
• Agent loop: <2000ms (with validation retry)

Resource Usage:

• Binary size: 45MB (optimized)
• Memory footprint: ~100MB (efficient)
• No external dependencies (single binary)

Quality Metrics:

• Overall pass rate: 93.1% (54/58 tests)
• Safe command categories: 100% (7/7 categories)
• False positive rate: 0% (52 safety patterns)

🐛 Known Limitations

Beta Constraints:

• MLX backend requires cmake to build from source
• Some E2E tests fail due to JSON parsing (P2 bug, doesn't affect users)
• Minor command variations possible (e.g., ls -la vs ls -l)
• Telemetry upload endpoint not yet deployed (queues locally)

Platform Support:

• ✅ macOS (Apple Silicon and Intel)
• ✅ Linux (x86_64 and ARM64)
• ⚠️ Windows: Experimental (not fully tested)
