fix(OMN-16416): emit hookEventName on lite-mode SessionStart; make venv bootstrap self-sufficient - #2021
Conversation
…nv bootstrap self-sufficient Re-land of #2019 (external contribution by andywu42), closed there for lacking Linear access / an OMN ticket / Evidence-Source per repo policy. Diff unchanged from the original PR. - plugins/onex/hooks/scripts/session-start.sh:145 -- the lite-mode hookSpecificOutput emission omitted hookEventName. Per tests/hooks/test_hook_event_names.py (OMN-9072), Claude Code drops additionalContext/suppressOutput/decision on any payload missing it. This path is live (hooks-delegation.v1.json), so every lite-mode session was losing its context injection. - plugins/onex/hooks/scripts/ensure-plugin-venv.sh:19 hard-failed (OMNI_HOME must be set) when run directly per the onboarding skill's own instructions, because it runs pre-venv-bootstrap and never sources common.sh's .env loading. Fix mirrors common.sh's own set -a / source ~/.omnibase/.env / set +a idiom. - Corrected a stale header comment claiming ensure-plugin-venv.sh "Runs as a SessionStart hook" -- it is not registered in hooks.json. Not in scope (deferred, per the original PR): scripts/check_hook_event_names.sh does a whole-file, not per-emission, grep for hookEventName -- how defect #1 went undetected. Follow-up ticket, not blocking this fix. Co-authored-by: andywu42 <112039811+andywu42@users.noreply.github.com>

…me check (#2044) Closes OMN-16490 Follow-up to OMN-16416 (#2021), which fixed `session-start.sh:145`. This fixes the guard that should have caught it. ## The hole `scripts/check_hook_event_names.sh` tested: ```bash if ! grep -q 'hookEventName' "$file"; then ``` That is a whole-**file** check. Any file with at least one conforming emitter masks every non-conforming one beside it. `session-start.sh` sets `hookEventName` at 1533/1542/1546, so the file passed while `:145` shipped a `hookEventName`-less SessionStart envelope — silently dropping `additionalContext` for every lite-mode session. ## The fix Walk each `hookSpecificOutput` mention; look for `hookEventName` within a proximity window; report `file:line`. A window is needed because one emission legitimately spans lines in **both** directions — jq pipelines put `hookEventName` first and chain `.hookSpecificOutput` assignments after it, while jq/python object literals open the envelope and set `hookEventName` later. **Window default is 12**, chosen empirically as the smallest value that clears every in-tree false positive. The binding case is `lane_termination_guard.py`, which builds the envelope at `:387` and mutates it at `:398`. Overridable via `HOOK_EVENT_NAME_PROXIMITY`. ## Keeping it usable The naive version reported **26 offenders on a clean tree** — it was matching prose. Excluded: shell/python comments, python docstring bodies (tracked by triple-quote state, including the opening line), the hook test harnesses, and an inline `# hook-event-name: not-an-emission` escape mirroring the allowlist-pragma convention already used here. Known limitation, documented in the script: two emissions closer together than the window can mask each other. Far smaller than whole-file matching, and it fails toward false-negative rather than blocking a correct push. ## Two call sites the stricter check surfaced - **`post-skill-delegation-enforcer.sh:88`** — emitted `{hookSpecificOutput: {}}` on its exempt path. A real defect: Claude Code rejects an envelope with no `hookEventName`. Now emits `hookEventName: "PostToolUse"`, matching the same file's other emission at `:105`. - **`skip_token_surface_guard.py:271`** — pragma added; an argparse `help=` string that merely names the field. ## Verification - Guard passes on current `dev` - Reintroducing the `:145` regression is caught **at that exact line**; the old `grep -q` passes the same file - `tests/hooks/test_hook_event_names.py` — 5/5 green, including its own synthetic negative case - Full `pre-commit run --hook-stage pre-push --all-files` clean (no new findings; the handful of secrets-scanner hits on unrelated pre-existing files — `metrics.py`, `node_golden_chain_sweep_orchestrator/__main__.py`, and pre-existing lines 22/68 in `skip_token_surface_guard.py` far from this PR's line-271 edit — are not introduced by this diff) ## Provenance Recreates the diff from stalled fork PR #2031 (verified byte-identical via `gh pr diff 2031`). #2031 could not be repaired in place: its branch (`awu42/omn-9072-emission-granular-guard`) and sole commit both name the ticket this work was originally filed under (OMN-9072), not the ticket it was refiled under after triage (OMN-16490) — tripping the Receipt Gate's identity-binding check — and the PR is from a fork (`maintainerCanModify=false`), so no fixing commit could be pushed to it. Per repo doctrine (spawn fresh lanes, not raw-ID resumes), this PR replaces #2031, which is being closed with a cross-reference to this PR. OCC evidence for OMN-16490 is already satisfied by the merged autobind companion onex_change_control#7037 (self-bind receipt `occ-self-bind-pr-7037`); a superseded manual companion attempt, onex_change_control#7058, is being closed as redundant. ## Ticket **OMN-16490** Evidence-Ticket: OMN-16490 Evidence-Source: OCC#7121 <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Bug Fixes** - Hook responses for approved delegation scenarios now correctly identify the `PostToolUse` event. - Improved hook-event validation detects mismatched event metadata more reliably and reports affected locations. - **Chores** - Refined help output to prevent unintended annotation or emission. - Refreshed the secrets baseline timestamp without changing detected entries or configurations. <!-- end of auto-generated comment: release notes by coderabbit.ai --> Co-authored-by: jonahgabriel <jonahgabriel@users.noreply.github.com>
