Sub-agents never own or mutate parent plans. Check recording (`completion_checks.go`) consumes engine outcomes only — a check passes when its declared tool actually ran and succeeded, never from claims inside tool output; a failed or unclassifiable effect invalidates earlier checks in the same batch. -- **Batch approval gate** — multiple risky tools shown in one prompt. `classifyToolCall` classifies each individual `shell` command, each `patch`/`write_file` target, and the `browser` tool; shows full commands; withholds blanket `SetTrustAll` when unclassifiable tools (incl.

MCP tools, classified `unknown`) remain. - **Tool-failure recovery** — retry transient errors, skip permanent failures, continue without crashing. Stall detection: 3 consecutive identical tool calls inject a corrective hint + fire `tool_recovery` — a hint, never aborts the run. - **Context-limit protection** — graduated trimming near the context window: old large tool results replaced with markers (4 most recent kept intact), then oldest turn groups dropped atomically (tool messages stay grouped with their parent). The protected head (system prompt, memory block, compaction digest, original task) is never dropped. The digest (body capped at an eighth of the budget) and the trim warning are reserved against the budget before groups are dropped, so the post-trim history fits. Token estimator counts tool schemas + reasoning content; safety margin self-tightens when provider-reported tokens exceed estimates (`margin_calibrated` signal). `trimToSurvival` handles provider context-length errors. **Rolling compaction** (on by default; `compaction: false` / `ODEK_COMPACTION=false` / `--no-compaction`) sketches dropped groups extractively into a rolling digest immediately, then a thinking-off side call replaces that sketch with a model digest on a later iteration if it arrives. - **Final-answer verification pass** (`internal/loop/verify.go`, optional) — after a candidate final answer, a side-call checks the answer against the run's evidence and can trigger corrective cycles. Config: `verify` section (`enabled`, `mode` hint|strict|off, optional cheaper `model`, `max_cycles` ≤ 3, `max_tokens`); default off, `hint` when enabled. Sub-agents are opted in only via an explicit `subagent.verify` section — `delegate_tasks` never enables it implicitly, so N children cannot multiply verify cost. @@ -215,7 +215,7 @@ Layered prompt-injection / approval-fatigue defenses.

(Force-push is `system_write` rather than auto-allowed `network_egress`.) Hooks, filters, editors, configured filesystem monitors and diff/merge drivers carry execution risk, and the escalation is repository-aware: `git status`, `add`, `commit`, `merge`, `gc`, `stash`, `restore`, `diff`, checkout/switch, rebase, cherry-pick, am, worktree/submodule mutations, and the verbs that refresh the index, compare the work tree or move objects (`revert`, `reset`, `clean`, `rm`, `mv`, `update-index`, `diff-files`, `diff-index`, `ls-files`, `grep`, `blame`, `describe`, `checkout-index`, `pull`, `fetch`, `push`) are `code_execution` only when the repository they target (the tracked cwd, `git -C`, `--git-dir`, or the nearest `.git` directory or gitfile, including linked worktrees and cloned submodules) is armed for that verb: an executable real hook script (not `*.sample`) or `core.hooksPath`/`hook.*.command`, `core.fsmonitor` naming a program, a `filter.*` clean/smudge/process command (plain `git-lfs` filters excepted), `diff.external` or a `diff.*` command/textconv driver, a `merge.*` driver, or an editor for a verb that opens one (`commit` without `-m`/`-F`/`-C`, `merge` without `--no-edit`, `rebase -i`), found in the repository, global or system git config, or the process environment. Config files are parsed minimally without following includes (an `include`/`includeIf` section counts as armed); an uncertain cwd, a missing or unreadable repository, hooks directory or config, an oversized config, or `GIT_DIR`-style environment overrides fail closed to `code_execution`. Command-line escalations are unconditional: `-c`/`--config-env` exec keys (including `include.path`), `--ext-diff`/`--textconv`, `--paginate`, `rebase --exec`, external merge strategies, `difftool`/`mergetool`, `bisect run`, `hook run` and `submodule foreach`. Unarmed, these verbs classify by their other effects (so `git checkout -- .` stays `system_write` and remote verbs stay `network_egress`).

Reads (`gh pr view`/`list`/`diff`, `gh issue list`, `gh repo view`/`clone`, `gh run view`, `gh search …`, `gh api` with a GET/HEAD (or no) method and no body flags, `gh auth status`) stay `network_egress`. Remote mutation (`pr merge`/`create`, `issue edit`, `release create`, `workflow run`, `secret set`, `gh api` with `-X POST`/`PUT`/`PATCH` or a body flag, a GraphQL `mutation`) is `system_write` (prompt). Irreversible deletion (`repo delete`, `release delete`, `gh api -X DELETE`, …) is `destructive`. `gh auth token` and `gh auth status --show-token` put a bearer token in the output, and login/logout/refresh change stored credentials, so they are `system_write`. Verbs that run a local program or shell alias (`extension install`/`exec`, `alias set` with a `!` expansion or `--shell`, `codespace ssh`/`cp`/`ports forward`, `copilot`, `config set editor`/`pager`/`browser`, git flags after `--` on `repo clone`) are `code_execution`. `run download`/`release download`/`repo clone` destinations (`-D`, `-O`, the clone directory, or the working directory) go through the write-target rules, so a download into `~/.ssh` or `.git/hooks` escalates. Only repo/host options (`-R`, `--repo`, `--hostname`, in any spelling) may precede the verb; an unrecognised command or verb, or any other option before the verb, is `unknown` (deny). `gh help`, `--help`, `--version` and `completion` stay `safe`. - `odek …` — any shell stage whose program basename is `odek` is `system_write`, so human-gated trust mutations (`odek memory promote`, `odek skill promote --force`, …) always require explicit operator approval and an injected agent cannot flip its own taint gates from inside a session. - `echo x >> ~/.bashrc`, `cp evil ~/.profile`, `dd if=evil of=~/.bashrc` — shell file operands and redirect targets are run through `ClassifyPath`, so writes to shell rc files, `~/.ssh`, `~/.odek` trust anchors, and other home-sensitive paths are `system_write` instead of auto-allowed `local_write`.

Matching is case-insensitive across full path components, so `~/.SSH/id_rsa`, `~/.AWS/credentials`, and `~/.ODEK/config.json` escalate on case-insensitive filesystems (macOS APFS, Windows NTFS). -- `chmod -R 777 /`, `chattr -R +i /`, `mv / /tmp/x` — the filesystem root itself classifies as `system_write`, so recursive permission/attribute flips or moves aimed at `/` prompt instead of falling through to auto-allowed `local_write`. `chattr` uses the same operand scan as `chmod`. +- `chmod -R 777 /`, `chattr -R +i /`, `mv / /tmp/x` — the filesystem root itself classifies as `system_write`, so recursive permission/attribute flips or moves aimed at `/` prompt instead of falling through to auto-allowed `local_write`. `chattr` uses the same operand scan as `chmod`. Moving a home directory away (`mv ~ /tmp/x`, `mv "$HOME" …`, `mv /home/user …`, or a directory above a home) is `system_write` too, like `mv -t /tmp/x ~`; moving files into the home directory stays `local_write`. The same holds for permission, ownership and in-place compression tools aimed at a home directory as a whole (`chmod -R 777 ~`, `chown -R x ~/`, `gzip -r ~`, `zstd --rm -r ~`), which reach `~/.ssh`, the shell rc files and the odek trust anchors; `chmod -R 755 ~/project` stays `local_write`. - `rm -rf ./`, `rm -rf ./..`, `rm -rf ././.` — every leading `./` is stripped before wipe-target matching so these are caught the same as `.` and `..`. -- `dd of=`, `tar -C /etc`, the archive of `tar -c`/`-r`/`-u` (`-f PATH`, `--file PATH`, `--file=PATH`), `unzip -d`, `7z -o…`, `pandoc --output=…`, `git archive --output`, `rsync … dest/` and rsync's `--write-batch`/`--only-write-batch`/`--log-file` files — write destinations are found in every spelling the tool accepts (`--opt=value`, a fused short option, the destination operand of rsync, dd's `of=`) and judged by the same path rules as a redirect target.

Unlike `persistence`, the session-trust shortcut stays available (friction rules still apply), and scheduled runs deny it unless `schedules.dangerous` allows it. **The `unread_exec` class (unread-script gate).** Executing a repo-supplied script — directly (`./env.sh`), via an interpreter (`bash env.sh`, `python tool.py`), or by sourcing it (`source env.sh`) — or by feeding it to an interpreter indirectly (`cat env.sh | bash`, `bash <(cat env.sh)`, `eval "$(cat env.sh)"`, `find -exec ./env.sh`, program-file options such as `awk -f`, `sed -f`, `make -f`, `gdb -x`, `vim -S`, `emacs --script`) — whose contents have not been read **in this session** gates as `unread_exec`. A read ledger (`danger.RecordRead`/`WasRead`) is populated by full-file `read_file` calls (a partial offset/limit window over a longer file does not count — the payload can ride below the fold), by `write_file` with the exact authored content, and by a successful plain `cat file` whose captured stdout matches the entire unchanged host file. `head`, `tail`, pagers, transformed output, shell syntax, container viewers, and partial patches do not grant execution-read trust. Native byte caps and the loop’s later output clipping/redaction invalidate delivery receipts; a tool read alone is not a delivered read. A **failed** read never licenses execution — the observed failure mode of a capable model whose `cat` errored on a path typo and fell back to running the file stays gated. The gate intercepts approval even when `code_execution` was set to `allow` or its class trusted (the entire point is per-script review), is never session-trust-shortcuttable (`danger.TrustShortcutAllowed`, all three approvers), and participates in configuration like a class: `"unread_exec": "deny"` blocks unread-script execution outright; `"unread_exec": "allow"` permits it only when the underlying class is also allowed — both must allow. **Fingerprinted licenses (TOCTOU).** The ledger binds each read to the file state at display time (size + mtime + SHA-256 of the exact displayed bytes, for files up to 1 MiB; larger files never receive a stat-only license): a file mutated after its read — via another tool, a lifecycle hook, or a background process — loses its license and the gate re-fires until the mutated content is re-read (re-reading renews the fingerprint, because now the model has seen THAT). **Pre-execution content audit.** When the gate prompts, the approval description carries content evidence from the local injection scanner over the target's leading 256 KiB, including a best-effort single-layer base64 (standard and URL-safe alphabets)/hex decode of embedded blobs — the human decides with the bytes, not just a path. The audit is read-only and never populates the ledger (the auditor is not the model). **Session-keyed ledgers.** Long-lived surfaces (`serve`, `telegram`, `schedule`) stamp `danger.WithLedgerKey` on the run context; file/shell tools record and gate against that key, so a read in session A cannot license execution in session B. An interpreter whose program operand only exists at run time (`bash "$(pwd)/x.sh"`, `bash "$DIR/x.sh"` with an unknown `DIR`, `xargs -I{} bash {}`) names a file no licence can be checked against, so it classifies `unknown` rather than running an unreviewed script behind a plain `code_execution` prompt; a process substitution (`bash <(cat x.sh)`) is a stream whose body is gated on its own. Ledgers are bounded (4096 paths per session, oldest evicted first; 1024 sessions, least recently used evicted first) and dropped with `danger.ForgetReadLedger` when a serve session is deleted, a Telegram chat is reset, or a scheduled run ends; eviction only removes a license, so the script gates again until re-read. A rewrite of the script inside the same command (`… > x.sh && bash x.sh`, `sed -i … x.sh; ./x.sh`) revokes its licence, a decoded or decompressed stream piped into an interpreter (`base64 -d … | sh`, `zcat … | python3`) classifies `unknown` because nobody has read its bytes, and fingerprinting never opens a non-regular file, so a FIFO cannot stall the gate. `Classify()` / `ClassifyScriptGate()` without a context still use the process-global default ledger (CLI-shaped tests and the classifier itself). @@ -214,7 +214,7 @@ When a classification is set to `prompt`, an approver pauses the agent until the - **Test binaries fail closed.** Inside a `go test` binary, the TTYApprover never opens the real controlling terminal — a test process without an explicit fixture TTY path (`/dev/tty` or empty) is denied outright instead of silently approving, covering both the test-binary case and the zero-value approver whose legacy path was fail-open.

The terminal transcript applies the same escaping to model- and tool-sourced text (tool calls and result summaries, streamed reasoning and answers, thinking, final answers, narration, errors, memory and skill notices): newlines and tabs are kept where the renderer prints multi-line text, emoji joiners are kept inside emoji sequences, tag characters are kept only inside the RGI subdivision flags (England, Scotland, Wales: U+1F3F4, the code spelled in tags, the cancel tag) — a tag run after a black flag is held, at most five tags, until the cancel tag decides, and any other run is escaped whole, as are tags anywhere else — and a multibyte character or two-byte C1 control split across stream fragments is held back until it is complete, so an escape sequence in a fetched page cannot rewrite what the operator reads. -**Batch approval card.** `classifyToolCall` (in the loop) classifies each individual `shell` command, each `patch`/`write_file` target, and the `browser` tool (action + URL → `network_egress`); MCP tools (detected by the `__` naming convention) classify as `unknown`.
