Changelog

0.3.8

• Query-time retrieval contract: docs/RETRIEVAL.md plus parent skill /sbc-retrieve. Parent spawns a child for Q&A; search and pack stay off the parent context.
• sbc_common.py pack --tiny --summary: 1 hop / 8 nodes, compact card-friendly stdout, bodies off, fail-closed token budget.
• Foundation retrievers stay in PKC / SAC / DEKC / RKC. Core does not absorb those agents.

0.3.7

• WikiTicket SDD (worklog) is the tracking system for this plugin.

0.3.6

• Three-host hooks: Codex + Cursor-native when Claude hooks exist.

0.3.5 — 2026-08-17

• Cursor host. .cursor-plugin/plugin.json (Cursor Plugins) plus .cursor/rules/second-brain.mdc. Docs: docs/CURSOR.md. docs/GROK_BOT.md now covers Grok Bot spawning Cursor cloud agents.

0.3.4 — 2026-08-17

• Fleet actor registry. If the operator actors.json lists actors, brain_session.py open fails closed on an unknown actor. No registry keeps the old behavior.
• Type allowlist. restrict maps a type to allowed actors. Pack + operator lists intersect. DailyDigest / WeeklyDigest are CoS-only.
• Pack roots are packing hints, not access control (docs/ISOLATION.md).
• Sample: actors.sample.json. Paths only.

0.3.3 — 2026-08-16

• ContextPack has a token budget: default 1/4 of the model window (SECOND_BRAIN_WINDOW_TOKENS, default 128000 → 32000 tokens). Override with --max-tokens or SECOND_BRAIN_PACK_MAX_TOKENS.
• Pack is fail-closed when the rendered subgraph exceeds the budget. Node clip (--max-nodes) is not a token budget and does not write a truncated pack.
• Bodies off unless that node is the pack root. Neighbors keep title, type, path, and frontmatter description only.
• Token estimate is chars/4. Success JSON reports tokens, budget, window.

0.3.2 — 2026-08-16

• Codex / Claude PostToolUse hook is fail-closed: sbc-hook-validate.sh runs sbc_common.py validate after apply_patch / Write / Edit and exits non-zero on a broken bundle.
• Removed the SessionStart print reminder (a reminder is not a harness).
• Writes outside a knowledge bundle stay a silent no-op.

0.3.1 — 2026-08-16

• Privacy: isolation tests and docs use only fictional lumenfield-detector / northstar-console actors.
• scripts/brain_session.py marked as the canonical isolation helper; foundation packs vendor this copy.

0.3.0 — 2026-08-15

• Grok Bot onboarding: docs/ONBOARDING.md (LLM-wiki history, destination state, public repo list)
• Full type ownership in docs/GROK_BOT.md (every registry noun, not a subset)
• Registry folders filled so writes land in the right catalog
• Linked Northstar sample graph (typed edges, packable in 2 hops)
• Version stamps aligned across plugin.json, marketplace, and package.json
• README related-plugins list now covers the whole suite plus foundations

0.2.0 — 2026-08-15

• Write isolation: scripts/brain_session.py (worktree + branch + PR)
• Required --author / SECOND_BRAIN_IDENTITY; emit WriteEvent on write
• Agent Plugins 1.0 root plugin.json
• docs/GROK_BOT.md, docs/LANG_CHAIN_DEEP_AGENTS.md, docs/ISOLATION.md
• Codex hooks (.codex-plugin + hooks/hooks.json)
• Skill sbc-session

• Nouns: Concept, ContextPack, TypedEdge, AgentIdentity, WriteEvent
• Skills: sbc-init, sbc-capture, sbc-pack, sbc-validate, sbc-doctor
