Target: fix(lib): restore env_flags/final_cmd initialization before kind-detection block (uncommitted working-tree change on .agents/skills/lib.sh, on top of commit b0c2c08)
Reviewer: cline
Output Report Path: .mam/jobs/785aa8a3/cline-reports/report-final.md

1. Delta Description

This changeset is the corrective fix for the critical regression identified in job 7479a065 (review of commit b0c2c08). The prior commit accidentally replaced the env_flags/final_cmd initialization block with the kind-detection block, orphaning $parsed and leaving $env_flags/$final_cmd permanently empty.

The fix is a 7-line uncommitted working-tree addition to .agents/skills/lib.sh (6 init lines + 1 blank separator), restoring the deleted block in its correct position — before the kind detection, after the parsed assignment:

    env_flags=""
    final_cmd="$run_cmd"
    if [ -n "$parsed" ]; then
      env_flags=$(echo "$parsed" | head -n 1 | tr '\t' ' ')
      final_cmd=$(echo "$parsed" | tail -n +2)
    fi

The shim (.mam/shim/herdr, untracked by git) contains the identical restoration at lines 141-146.

3. Behavior (동작성)

3.1 Initialization restored correctly

The restored block (lib.sh:260-265) is the exact 6-line sequence deleted by b0c2c08, confirmed identical to the parent commit 20e2e9b via git show 20e2e9b:.agents/skills/lib.sh. Placement is correct:

Position	Before this fix (`b0c2c08`)	After this fix
`parsed` (lib.sh:246-258)	computed, never consumed (orphaned)	✅ consumed at lib.sh:263-264
`env_flags` (lib.sh:260,263)	never set → empty in eval	✅ set from `parsed` line 1
`final_cmd` (lib.sh:261,264)	never set → empty in strip & eval	✅ set from `run_cmd` / `parsed` line 2+
`kind` detection (lib.sh:267-280)	`$final_cmd` empty → grep no-ops	✅ `$final_cmd` populated → grep works
strip block (lib.sh:283-294)	operates on empty → empty output	✅ operates on real binary+args → strips correctly
dual-syntax fallback (lib.sh:324-328)	`--` (no command)	✅ `-- $final_cmd` with real command

3.2 End-to-end simulation (executed)

Input: run_cmd = 'FOO=bar cline --flag value'

parsed = '--env FOO=bar\ncline --flag value'
env_flags = '--env FOO=bar'                    ← restored: parsed line 1
final_cmd (before strip) = 'cline --flag value' ← restored: parsed line 2+
final_cmd (after strip) = '--flag value'       ← strip removes leading 'cline'
agent start: _real_herdr agent start NAME --kind cline --workspace WS --cwd WS $split_flag --env FOO=bar -- --flag value

All three features from b0c2c08 now function correctly:

Env-var forwarding: --env FOO=bar is passed to herdr agent start. ✅
Kind detection: $final_cmd = 'cline --flag value' → grep -qi "cline" matches → kind="cline" (or from $name). ✅
Strip: leading cline token removed → --flag value passed after --. ✅
Dual-syntax fallback: first try uses --kind cline -- --flag value; fallback uses -- cline --flag value. ✅

3.3 Shim consistency

.mam/shim/herdr (untracked) contains the identical restoration and all downstream blocks:

Block	lib.sh lines	shim lines	Match
init (restored)	260-265	141-146	✅ IDENTICAL (diff)
kind detection	267-280	148-161	✅ IDENTICAL (diff)
strip block	282-294	163-175	✅ IDENTICAL (diff)
agent-start (dual syntax)	324-328	205-209	✅ IDENTICAL (diff)

Full diff of lib.sh:260-294 vs shim:141-175 = IDENTICAL.

4. Loss / Hygiene (유실)

Item	Status
`$parsed` — now consumed at lib.sh:263-264 (no longer orphaned)	✅ Fixed
`$env_flags` — now set from `parsed` line 1	✅ Fixed
`$final_cmd` — now initialized from `run_cmd`/`parsed` before strip & eval	✅ Fixed
`$final_cmd`-based kind detection (lib.sh:274-279) — now operates on non-empty `final_cmd`	✅ Fixed
Change is purely additive (7 lines added, 0 removed) — no collateral deletion	✅ Surgical
Shim (untracked) updated identically	✅ Consistent
Working tree: only `lib.sh` modified + untracked report file	✅ No stray artifacts
New tests for new-session flow	❌ None (pre-existing limitation — requires real `herdr` binary; unchanged by this fix)

5. Test Results

Suite	Result	Time
`test_workspace_scope.py` + `test_tier1_unit.py -k 'resolve_herdr_session or derive_session_name'`	5 passed	0.65s
`test_orc_onboard.py` (cross-regression)	40 passed	6.35s

No cross-regression. The new-session flow (env_flags/final_cmd/strip/dual-syntax) remains untested (requires a real herdr binary — pre-existing limitation, unchanged by this fix). The regression it fixes was likewise silent; the simulation in §3.2 provides the behavioral verification that tests cannot.

6. Verdict

The fix is a surgical, purely additive restoration of the 6-line env_flags/final_cmd initialization block that was accidentally deleted by commit b0c2c08. The lines are restored in the correct position (after parsed, before kind detection), are byte-identical to the parent commit 20e2e9b, and resolve all four consequences of the prior regression: $parsed is consumed, $env_flags is populated, $final_cmd is initialized before the strip block, and the $final_cmd-based kind-detection branches are live. The end-to-end simulation confirms the full agent-start command is now correct with env-var forwarding and binary stripping both functioning. The shim (untracked) is updated identically across all four blocks. bash -n passes, the strip-block Python compiles, and 45 tests pass with no cross-regression. No design-level rework is needed.

[VERDICT: PASS]
