feat(runtime): complete the hook, MCP, and memory portability inventories

The new inventories doc maps what's actually Claude-bound. Hooks: only PreCompact and Stop-teardown carry porting decisions, both now decided (prose downgrade, Codex notify or manual). MCP: everything ports mechanically except paging, since signal-mcp exists only claude.ai-side, so the Signal-pager task gains runtime portability as a second motivation. Memory: the KB is already the cross-agent store, and knowledge-base.md now tells agents without harness memory to capture into the session log. Three inventory child tasks closed as dated entries under the generic-agent-runtime parent.

 *** 2026-07-13 Mon @ 05:16:37 -0500 Folded home's ownership ack + current-state report into the reconcile scope
 home confirmed (2026-07-11 reply) rulesets owns this task and the two-paths reconciliation is the right first step. New facts for the reconcile: from a home session on 2026-07-09, signal-mcp was NOT connected, and the local signal-cli is registered as Craig's own number — =send --note-to-self= returns a message id but produces no phone push. So home currently has no working ad-hoc page channel at all; whatever the runbook lands on must give home a live path.
 
+*** 2026-07-13 Mon @ 14:40:00 -0500 Added runtime-portability as a second motivation (Craig approved)
+The MCP portability inventory ([[file:docs/design/2026-07-13-runtime-portability-inventories.org]]) found signal-mcp exists only claude.ai-side — no local config anywhere — so a non-Claude agent (Codex-style or local LLM) has no paging path at all. The signal-cli runbook this task produces is therefore also the runtime-neutral page channel, not just home's replacement for ntfy.

 *** TODO Skill parity across runtimes
 The user-invoked skills (voice, review-code, flush, …) are Claude Code registrations wrapping portable markdown prompts. Decide per skill: re-register in the target harness's custom-command system, or fold into =.ai/workflows/= (already runtime-neutral). Model-invoked skills need a per-harness answer or graceful absence (commits.md already defines the /voice-unavailable fallback pattern).
 
-*** TODO Hook parity inventory
-Inventory every settings.json hook (AskUserQuestion hard-deny, PostToolUse validators, wrap-teardown Stop hook, session-clear-resume) and map each to the target harness's mechanism or an accepted prose-only downgrade. The deny hooks exist because prose enforcement failed — a downgrade is a real regression, so decide per hook, not wholesale.
+*** 2026-07-13 Mon @ 13:34:17 -0500 Hook parity inventoried — only two hooks carry real porting work
+Full mapping in [[file:docs/design/2026-07-13-runtime-portability-inventories.org]]. AskUserQuestion deny is moot off Claude (no popup tool to deny); PostToolUse validators survive via the bundles' git pre-commit hooks; clear-resume folds into the session-plumbing child; session-title is cosmetic. Real gaps: PreCompact priority-save (prose downgrade) and Stop wrap-teardown (Codex notify / manual elsewhere) — decisions in the VERIFY below.

-*** TODO Memory story for non-Claude agents
-Claude's auto-memory is harness-owned. The org-roam KB is the designed cross-agent store — document that a non-Claude agent skips harness memory and leans on the KB + session files, and verify knowledge-base.md reads cleanly for a non-Claude reader.

+Details in [[file:docs/design/2026-07-13-runtime-portability-inventories.org]]. Auto-memory stays Claude-owned; non-Claude agents use the org-roam KB + file artifacts (todo/notes/session anchors), all runtime-neutral already. One wording gap: knowledge-base.md's capture-then-promote names harness memory as the capture layer — a one-sentence addition (session log as the capture layer for agents without harness memory) closes it, pending approval in the VERIFY below.

+*** 2026-07-13 Mon @ 13:34:17 -0500 MCP portability checked — portable except paging
+Details in [[file:docs/design/2026-07-13-runtime-portability-inventories.org]]. Nine locally-configured servers (linear, notion, figma, slack-deepsat, google-calendar, google-docs x2, drawio, google-keep) port mechanically to any MCP-speaking harness. claude.ai-managed connectors (Gmail + claude.ai Calendar/Drive) don't travel but are redundant with local servers / cmail-action. The real finding: signal-mcp is NOT locally configured anywhere — the protocols.org paging path is claude.ai-side only, so off Claude there is no page channel. The Signal-pager [#C] task's signal-cli runbook is the fix; add runtime-portability as motivation there (VERIFY below).
 
-*** TODO MCP portability check
-MCP is cross-vendor; the self-hosted servers (signal-mcp, google-calendar, linear, slack) should attach to any MCP-speaking harness — verify. The claude.ai-managed connectors (Gmail, Drive, Calendar) don't travel; list self-hosted replacements where a workflow depends on them.
+*** 2026-07-13 Mon @ 14:40:00 -0500 Four inventory decisions — Craig approved all four
+Recorded in [[file:docs/design/2026-07-13-runtime-portability-inventories.org][the inventories doc]]: prose-only PreCompact downgrade off Claude; Stop-teardown via Codex notify where available, manual elsewhere; runtime-portability note added to the Signal-pager task; capture-layer sentence added to knowledge-base.md (non-Claude runtimes capture into the session log and promote from there).
 
 *** TODO Local model floor evaluation
 The workflows assume long-context instruction-following (startup's multi-file read; the commits.md publish chain). Establish the minimum viable local tier (likely strong-70B+/MoE, 100k+ context), and what compensations a weaker model needs: shortened protocols, more checklist gates, more hook-level enforcement. Feeds the spec's "default local runtime/server" and "first supported local editing CLI" blocker decisions.
