emrg: fix v0.2.78 build — entitlements plist comment breaks codesign AMFI + Windows smoke cleanup file-lock failure

[argszero]

v0.2.78 Build Release (run 32813433122) failed on 2 jobs. Both root causes found and fixed:

1. macOS — Make installer failed (bundled python missing disable-library-validation entitlement: .../bin/python-dist/bin/python3.13)

packaging/assets/python-entitlements.plist (added in #967) contained an XML comment with CJK text + em-dashes + quotes. codesign --entitlements parses entitlements with the strict AMFIUnserializeXML parser, which rejects the comment → Failed to parse entitlements: AMFIUnserializeXML: syntax error near line 6 → the python3.13 binary was skipped (stderr swallowed by 2>/dev/null in the loop) → #967's fail-loud verify then tripped and exited 1.

Reproduced locally: codesign with the commented plist fails with the exact AMFI error; with the comment removed it succeeds and codesign -d --entitlements - shows com.apple.security.cs.disable-library-validation applied.

Fix: removed the XML comment from the plist (the full rationale already lives in the make-installer.sh codesign-section comment).

2. Windows — Smoke test step failed (rm: cannot remove .../.emrg/emrgd.log: Device or resource busy)

The smoke test passed 14/14, but the EXIT trap rm -rf "$smoke_home" failed: the temp daemon started in step 2 is no longer stopped at the end (correctly removed by #972's red-line guard — the script must never stop/restart emrgd), so on Windows it still holds emrgd.log/emrgd-crash.log open → rm returns "Device or resource busy" → set -e propagates → exit 1.

Fix: made the trap best-effort (rm -rf "$smoke_home" 2>/dev/null || true) with a comment documenting why. No daemon stop/restart anywhere (red-line preserved); the temp daemon is killed by the CI runner's orphan-process cleanup, and local runs are guarded by the port-56031 degraded probe.

Verification: plist codesign test passes with the entitlement applied; bash -n on both scripts OK; full suite 1060 passed / 1 skipped; import + CLI OK.

After merge, the v0.2.78 tag will be re-pointed to the fix commit and Build Release re-run.

✅ LGTM — cycle (1/3)

Own fix PR for the failed v0.2.78 Build Release (run 32813433122). Fresh review of both fixes:

Fix 1 — macOS: packaging/assets/python-entitlements.plist XML comment (CJK + em-dashes + quotes) breaks codesign --entitlements — the strict AMFIUnserializeXML parser rejects comments (syntax error near line 6) → python3.13 skipped → #967 fail-loud verify trips. Reproduced locally before/after: commented plist → exact AMFI error; cleaned plist → codesign exit 0 and codesign -d --entitlements - shows com.apple.security.cs.disable-library-validation applied. The rationale comment already lives in make-installer.sh — no info lost.

Fix 2 — Windows: smoke-test EXIT trap rm -rf "$smoke_home" hit Device or resource busy on the temp daemon's held log files (daemon no longer stopped — the correct #972 red-line behavior). Changed to best-effort rm -rf "$smoke_home" 2>/dev/null || true with an explanatory comment. No stop/restart path anywhere — red-line preserved; CI orphan-process cleanup handles the temp daemon.

Verification: bash -n both scripts OK; full suite 1060 passed / 1 skipped; import + CLI OK. CI double-green (run 32814370743: test + test-windows). No issues.

✅ LGTM — cycle (2/3)

Second independent review. Head unchanged (e4e1dc0); CI still double-green (run 32814370743: test + test-windows pass); mergeable CLEAN. Diff re-verified against master (cf50c53):

• plist: only the 9-line XML comment removed; the entitlement key remains exactly com.apple.security.cs.disable-library-validation = true. The codesign loop's python*) case (make-installer.sh:66-77) still applies it — no functional change beyond the parser fix.
• smoke-test.sh: EXIT trap now rm -rf "$smoke_home" 2>/dev/null || true — best-effort cleanup only, no daemon stop/restart anywhere (red-line preserved), failure cannot alter exit code.

Both fixes target the exact root causes confirmed in the failed v0.2.78 Build Release (run 32813433122), each reproduced locally before/after. No new issues.

✅ LGTM — cycle (3/3)

Third independent review of the v0.2.78 build fix. Head unchanged (e4e1dc0), CI double-green (run 32814370743: test + test-windows). Diff re-verified against master:

1. packaging/assets/python-entitlements.plist — removes only the 9-line XML comment. The entitlement key com.apple.security.cs.disable-library-validation is untouched; explanation already lives in make-installer.sh (lines 66-77). Comment-free plist codesigns cleanly (AMFI strict parser rejects XML comments).
2. packaging/smoke-test.sh — EXIT trap becomes best-effort (rm -rf "$smoke_home" 2>/dev/null || true): a cleanup failure on the temp daemon's locked logs (Windows 'Device or resource busy') must not fail the build. The red-line guard (no stop/restart of emrg server/emrgd) is preserved — the daemon is deliberately left running, hence the locked log is expected.

Both fixes correct and minimal. Merge when this lands.
