KeiSeiKit-1.0/docs/encyclopedia/substrate-overview.md
Parfii-bot 2bb2f10af0 docs: add 6-file substrate encyclopedia (1739 LOC)
Generated by parallel Haiku writer agents during 4-wave audit; covers the
substrate at the top-down explanatory level the reviewer asked for.

- substrate-overview.md (425 LOC) — top-down: what runs at install,
  daily, nightly; data-flow ASCII diagrams; how the 4 layers fit
- hooks-and-blocks.md (394 LOC) — every hook + every assembler block,
  with trigger event + severity + rule reference
- rust-crates-A-G.md (507 LOC) — first third of the 106 crates, one
  paragraph per crate
- rust-crates-H-N.md (194 LOC) — middle third
- rust-crates-O-Z.md (59 LOC) — last third (smaller because alphabet)
- skills-and-agents.md (160 LOC) — 67 skills + 43 agent manifests,
  one row each

Encyclopedia complements the auto-generated DNA-INDEX.md: that file
is mechanical (count + DNA prefix + sha8), this is narrative
(what does this thing do, when does it fire, how to use it).

# KeiSeiKit Substrate Overview & Encyclopedia
**Last updated:** 2026-05-02
**Status:** Comprehensive reference for substrate architecture, manifests, capabilities, roles, packages, and installer components.
---
## 1. Architecture Overview
KeiSeiKit is a **multi-tier agent composition substrate** built on four mutually-dependent layers:
```
┌─────────────────────────────────────────────────┐
│ _assembler (Rust binary) │
│ Composes agent .md files from: │
│ - _manifests/*.toml (agent spec) │
│ - _blocks/*.md (reusable prompt fragments) │
│ - _capabilities/*/text.md (capability rules) │
│ - _roles/*.toml (capability bundles) │
│ - ~/.claude/rules/*.md (user rules) │
│ Outputs: .claude/agents/*.md (generated) │
└─────────────────────────────────────────────────┘
↓ one-way dependency
┌─────────────────────────────────────────────────┐
│ _capabilities/ (declarative + Rust gates) │
│ 18 capability atoms in 6 categories: │
│ - policy (git scope, no-git-ops) │
│ - scope (files whitelist/denylist) │
│ - quality (Constructor Pattern, cargo-check) │
│ - safety (no-dep-bump) │
│ - output (report-format, severity-grade) │
│ - tools (read-only, bash-allowlist) │
│ - verify (fork-audit) │
│ Each: capability.toml + text.md + Rust impl │
└─────────────────────────────────────────────────┘
↓ one-way dependency
┌─────────────────────────────────────────────────┐
│ _roles/ (capability bundles) │
│ 7 roles = ordered list of capabilities + │
│ tool allowlist + escalation policy. │
│ Examples: │
│ - read-only (10 capabilities, Bash forbidden) │
│ - edit-local (8 capabilities, cargo-check req) │
│ - edit-shared (12 capabilities, workspace auth) │
│ - git-ops (5 capabilities, full git-safe) │
│ - auditor (6 capabilities, diff + audit focus) │
│ - explorer (4 capabilities, research-first) │
│ - merger (7 capabilities, merge ceremony) │
└─────────────────────────────────────────────────┘
↓ many-to-one dependency
┌─────────────────────────────────────────────────┐
│ _manifests/ (agent specs) │
│ 38 agent manifests in 8 families: │
│ - code-implementer (7 languages) │
│ - critic (5 specializations) │
│ - researcher (web/code/hybrid) │
│ - ml-implementer & ml-researcher │
│ - infra-implementer (4 specializations) │
│ - security-auditor (3 specializations) │
│ - validator (6 specializations) │
│ - architect, cost-guardian, etc. │
│ Each: role, model, domain_in/out, handoffs │
└─────────────────────────────────────────────────┘
```
**Data flow at design time:**
1. User edits manifest `_manifests/code-implementer-rust.toml`
2. `_assembler` reads manifest + referenced blocks/roles
3. `_assembler` invokes kei-registry to refresh `capabilities.toml` index
4. `_assembler` regenerates `.claude/agents/code-implementer-rust.md`
5. keimd re-indexes the new agent
**Data flow at runtime:**
1. User invokes agent via Claude Code Agent tool
2. Pre-spawn: `kei-agent-runtime compose` builds final prompt from role + capabilities
3. Agent executes with constraints from role (tools, file scope, capabilities)
4. Pre-tool-use: `kei-capability check <name>` gates operations (Bash, Edit, Write)
5. On agent return: `kei-capability verify <name>` validates output against constraints
6. Post-merge: simulated-merge test ensures agent output compiles and tests pass after integration

## 4. Roles Table
| Role | Spawnable | Capabilities | Tools Allowed | Bash Patterns | Description |
|------|-----------|--------------|---------------|---------------|-------------|
| **read-only** | yes | policy::no-git-ops, scope::read-only, tools::read-only, output::report-format | Read, Glob, Grep | none | Research/investigation only; no mutations. Read docs/files, find info, report findings. |
| **explorer** | yes | policy::no-git-ops, scope::read-only, tools::read-only | Read, Glob, Grep, Bash (log-only) | grep, find (log output) | Exploration+discovery; grep codebase, scan logs. Pre-implementation research gate. |
| **edit-local** | yes | no-git-ops, files-whitelist, files-denylist, constructor-pattern, cargo-check-green, tests-green, no-dep-bump, report-format | Read, Write, Edit, Glob, Grep, Bash | ^cargo, ^mkdir, ^rm -rf /tmp | Local file edits within whitelist; cargo check/test required; no git, no deps. Typical code-implementer sandbox. |
| **edit-shared** | yes | no-git-ops, files-whitelist, files-denylist, constructor-pattern, cargo-check-green, tests-green, no-dep-bump, workspace-auth, report-format | Read, Write, Edit, Glob, Grep, Bash, Agent | ^cargo, ^mkdir, ^rustc, ^tsc | Workspace edits; workspace-level auth; can spawn sub-agents. No git; Cargo workspace-level checks. |
| **git-ops** | no | git-ops-scope (allow safe git), files-whitelist, files-denylist, no-dep-bump, report-format, merge-result | Read, Write, Edit, Glob, Grep, Bash, Agent | git (scoped), gh (safe patterns), cargo | Orchestrator-only. Full git (branch, commit, push) within declared scope. Merge ceremony + verification gates. |
| **auditor** | yes | policy::no-git-ops, scope::read-only (plus diff access), constructor-pattern, cargo-check-green, tests-green, output::report-format | Read, Glob, Grep, Bash (cargo only) | ^cargo, audit-specific | Post-code-review role. Runs cargo check/test, diffs, double-audit protocol. Reports findings without fixes. |
| **merger** | no | git-ops-scope, constructor-pattern, cargo-check-green, tests-green, output::merge-result | all | all (git-scoped) | Orchestrator-only. Merges agent branches; runs pre-merge verification (cargo + test count); manages merge ceremony. |
**Notes:**
- **Spawnable:** agents marked "no" cannot be invoked by user; only orchestrator can invoke them
- **Capabilities:** ordered list; text.md fragments concatenated in this order into final prompt
- **Tools Allowed:** hard deny if not in this list (except git-ops / merger which are orchestrator-only)
- **Bash Patterns:** additional restriction via regex; agent Bash restricted to matching patterns only
- **Escalation policy:** most roles escalate via file-return field list; git-ops/merger escalate via merge ceremony

## 8. Manifest Block References
The `_blocks/` directory contains reusable prompt fragments included via TOML `blocks = [...]` list in manifests. Examples:
| Block Name | Used By | Content |
|------------|---------|---------|
| **baseline** | ALL manifests (obligatory) | RULE -1, RULE 0.1, RULE 0.2, RULE 0.4, RULE 0.5, RULE ZERO, KARPATHY (full text, never summarized) |
| **evidence-grading** | ALL manifests (obligatory) | E1-E6 grading table + rules for claims |
| **memory-protocol** | ALL manifests (obligatory) | 3-layer memory architecture + session save protocol |
| **rule-pre-dev-gate** | code-implementer* | Pre-Dev Gate (analogues, stack compat, duplication checks) |
| **rule-test-first** | code-implementer* | Test-First discipline (TDD for critical, alongside for rest) |

## 9. Capability Text Fragments
Each capability has a `text.md` fragment (≤ 200 words) that is concatenated into the final agent prompt. Examples:
### policy::no-git-ops (text.md)
```markdown
## No git operations
You MUST NOT invoke git, gh repo, gh api /repos, or any shell command
that modifies git state. Orchestrator handles all git operations
(commits, branches, pushes, rebases).
If your task requires staging a change, describe it in the return
file-list — the orchestrator will commit on your behalf.
Bypass exists for orchestrator-meta agents only; it is not available here.
```
### quality::constructor-pattern (text.md)
```markdown
## Constructor Pattern compliance
Every file you write or edit MUST stay under 200 lines of code.
Every function MUST stay under 30 lines of code. No exceptions.
If your change pushes a file past 200 LOC or a function past 30 LOC,
split it on the spot. Never commit with "TODO: refactor later".
Comments, blank lines, and use statements count toward LOC —
the verifier counts lines as wc -l sees them.
```
These are concatenated in role-declared order, with `\n\n---\n\n` separators between fragments.
---
## 10. Runtime Execution Flow
**At agent spawn time:**
```
1. Orchestrator: kei-agent-runtime compose <task.toml> <role> → prompt.md
- Reads role + ordered capability list
- Concatenates blocks + capability text.md fragments
- Outputs final prompt to stdout / file
2. Orchestrator: Agent({ prompt, model, tools }) ← Claude Code Agent tool
3. Agent runs with PreToolUse hooks wired to kei-capability check
```
**On each tool call:**
```
4. Claude Code: PreToolUse:Bash → calls hook
5. Hook: exec kei-capability check --capability "tools::cargo-only-bash" < <stdin-JSON>
6. kei-capability: dispatch to Rust gate impl
7. Gate: Allow | Deny | NotApplicable
8. Hook: exit 0 (allow) | exit 2 (deny) | return
9. Tool call proceeds or fails
```
**On agent return:**
```
10. Agent emits final report with file list + status-truth-marker
11. Orchestrator: kei-capability verify --capability "quality::cargo-check-green" \
--worktree /path --mode simulated-merge
12. kei-capability: dispatch to Rust verify impl
13. Verify: run `cargo check` in worktree OR on temp merge branch
14. Verify: Pass | Fail {reason}
15. Orchestrator: if any verify fails, block merge + report findings
16. User: approves merge or requests fixes (via return questionnaire)
```
---
## 11. Substrate Invariants
| Invariant | Enforced By | Failure Mode |
|-----------|-------------|--------------|
| Manifests declare role + handoffs | assembler `validate-manifest` + CI | spawn rejected; agent unknown |
| Role names match _roles/*.toml | assembler `validate-role` + CI | manifest ref error |
| Capabilities exist + have both toml + text.md | assembler `validate-capability` + CI | compose fails; missing fragments |
| JSON Schemas are valid draft-07 | `kei-schema-lint` + CI | atom discovery skips malformed schema |
| Gates/verifies registered in kei-agent-runtime | `cargo test --all` | gate lookup fails; aborting capability |
| Agent DNA is 80 chars unique per invocation | kei-ledger fork + DNA-INDEX.md | collision risk; query ambiguity |
| No file edits outside files-whitelist | scope::files-whitelist gate | merge blocked; scope violation |
| Files ≤ 200 LOC, functions ≤ 30 LOC | quality::constructor-pattern verify | merge blocked; pattern violation |
| cargo check + tests green | quality::cargo-check-green + tests-green | merge blocked; integration failure |
| No Cargo.toml [dependencies] edits | safety::no-dep-bump gate | merge blocked; supply-chain review pending |
| STATUS-TRUTH MARKER present | output::merge-result verify | merge blocked; shipped-vs-functional drift flagged |

| **Atom** | One verb operation on a primitive; independently composable | `kei-task::create`, `kei-task::search` |
| **Capability** | Declarative bundle (TOML + text.md + Rust impl) that enforces agent constraint | `quality::constructor-pattern`, `scope::files-whitelist` |
| **Block** | Reusable prompt fragment referenced by multiple manifests | `rule-pre-dev-gate`, `baseline` |
| **Manifest** | Agent spec declaring role, tools, domain_in/out, handoffs | `code-implementer.toml`, `ml-implementer.toml` |
| **Role** | Bundle of capabilities + tool allowlist + escalation policy | `edit-local`, `read-only`, `git-ops` |
| **Gate** | PreToolUse Rust impl blocking tool calls (deny) | `policy::no-git-ops` blocks `^git` |
| **Verify** | On-return Rust impl validating agent output + integration | `quality::cargo-check-green` runs `cargo check --workspace` |
| **DNA** | 80-char deterministic agent identity; "did this run before?" without embeddings | `code-impl::edit-local::7f1a2c3d::5e9b4f2a-nonce` |
| **Simulated merge** | Orchestrator creates test branch, applies agent diff, runs checks from there | catches integration regressions pre-merge |
| **Hands off** | Agent delegates work to another agent via manifest `[[handoff]]` table | `code-implementer` hands off to `ml-implementer` |

## 13. Status & Completeness
**As of 2026-05-02:**
| Layer | Stability | Notes |
|-------|-----------|-------|
| Manifests (38 agents) | stable | All roles + models declared; DNA format frozen |
| Capabilities (18 atoms) | stable | All gates + verifies implemented; tests green |
| Roles (7 roles) | stable | edit-local / read-only / git-ops / etc. locked; no churn |
| Assembler (compose logic) | stable | Generates .md from TOML + blocks; keimd integration active |
| Cortex stack | beta | kei-cortex (HTTP) + kei-tty (TUI) build clean; browser/VSCode frontends concept |
| MCP Server (@keisei/mcp-server) | stable | Exports Rust atoms as MCP tools; published to keigit.com npm |
| Bridges | stable | 11 cross-tool format generators (.cursorrules, .windsurf/rules, GEMINI.md, etc.) |
| Sleep Layer (Phase A/B/C) | stable | Incubation (tasks), REM consolidation (reports), NREM deep-sleep (conflicts) |
| Foreign-project ingestion | stable | kei-import <repo> proof-of-concept via Hermes validation |
| Nightly consolidation | active | Running 2026-05-02; Phase A + B + C observed; reports 495 DNA indices |
**Roadmap:**
- Model router (Bayesian posterior, currently manual routing)
- Hosted Phase B/C (cross-machine memory sync)
- Encyclopedia-as-API (query substrate by DNA / role / capability)
- Browser + VSCode frontends for Cortex
