+# ADR: Codex current-controller epoch and one-shot write lease
+
+Date: 2026-08-19
+State: accepted source contract; host integration package implemented
+
+## Context
+
+Multiple Codex tasks can remain alive at the same time. A task may hold a real
+human authorization from an older conversation and continue using tools after
+the human has moved to a newer language channel. A prompt reminder cannot
+deterministically revoke the older task's tool capability. Task-to-task
+delegation can also be misclassified as direct human speech if every
+`UserPromptSubmit` is labeled identically.
+
+## Decision
+
+1. Direct human input creates a new global local `control_epoch` bound to the
+   exact Codex session and turn.
+2. Known task delegation and system/agent delivery are separate source classes.
+   They do not claim direct-human provenance, TCS human perception, controller
+   status or execution authority.
+3. Capability tools in all non-current Codex sessions are denied by a
+   `PreToolUse` guard.
+4. Current-session local editing remains available. Remote Git writes, external
+   publishing/deployment and destructive cleanup additionally require a
+   one-shot lease bound to the current epoch, session, turn, category and exact
+   working directory, with a maximum lifetime of fifteen minutes.
+5. A new direct prompt revokes any unconsumed lease.
+6. Trusted hook definitions pin the SHA-256 of installed scripts so a source
+   change requires a new visible Codex hook review.
+
+## Boundary
+
+This host bridge is a language-source and execution-admission boundary. It is
+not a persona, model rule, platform rule, identity proof, repository authority
+or server authority. Runtime state, raw human messages, leases, credentials and
+trust receipts remain local and are excluded from the repository.
+
+## Rejected alternatives
+
+- Keep old authorization active until the old task voluntarily stops: a newer
+  human channel would have no deterministic control boundary.
+- Disable all local execution globally: this would remove useful current-task
+  agency instead of separating current and stale tasks.
+- Infer write leases from keywords in natural language: negation, discussion
+  and quoted text can contain the same words as authorization.
+- Treat persona binding as execution authority: continuity and external action
+  admission are separate predicates.
+- Trust only a stable script path: the bytes behind the path could change
+  without changing the reviewed hook command.

+# GuangHu Codex Host Bridge v1
+
+This package compiles a small host-side boundary for Codex tasks. It does not
+define a persona, change model or platform rules, or grant repository/server
+authority.
+
+## What it enforces
+
+- A direct human `UserPromptSubmit` advances one global current-controller
+  epoch for the local Codex installation.
+- Wrapped Codex task delegations are recorded as non-human delivery and never
+  impersonate direct human speech or claim controller status.
+- Capability tools in stale Codex tasks are denied by `PreToolUse`.
+- Remote Git writes, external publishing/deployment, and destructive cleanup
+  require a current-turn, exact-working-directory, time-limited one-shot lease.
+- Hook commands pin the SHA-256 of installed runtime scripts. A changed script
+  requires regeneration of the hook definition and visible Codex review.
+
+## What is never published by this package
+
+Runtime state stays under the local `CODEX_HOME`: raw messages, numbered
+events, the current controller, leases, trust state, credentials and keys.
+This repository contains only source, tests, installer logic and architecture
+documentation.
+
+## Install
+
+```bash
+node scripts/install.mjs \
+  --subject-id "ICE-GL∞" \
+  --subject-name "冰朔" \
+  --carrier-role "CODEX_SUMMARY_PROMPTER_ONLY"
+```
+
+The installer preserves unrelated hooks, installs the runtime under
+`$CODEX_HOME/runtime/guanghu-codex-host-bridge/v1`, and writes hash-pinned
+`UserPromptSubmit` and `PreToolUse` entries. Codex must then visibly review and
+trust the changed hook definitions.
+
+Optional environment variables:
+
+- `CODEX_HOME`: defaults to `~/.codex`.
+- `GH_HUMAN_MEMORY_ANCHOR`: optional durable-memory pointer added to the thin
+  source envelope; no memory body is copied.
+- `GH_CODEX_CONTROL_ROOT`: overrides the local controller/lease state folder.
+
+## Issue a one-shot lease
+
+Only after explicit authorization in the current direct-human turn:
+
+```bash
+node "$CODEX_HOME/runtime/guanghu-codex-host-bridge/v1/write-lease.mjs" issue \
+  --session-id '<current-session>' \
+  --turn-id '<current-turn>' \
+  --category remote_git \
+  --cwd '/exact/repository/path' \
+  --target 'origin/main' \
+  --reason 'explicit current-turn authorization'
+```
+
+The next matching high-risk action consumes the lease before execution. A new
+direct prompt, expiry, category mismatch, directory mismatch, session mismatch
+or turn mismatch invalidates it.
+
+## Test
+
+```bash
+node --test tests/*.test.mjs
+```
