* fix(execenv): overlay per-task HERMES_HOME so Hermes discovers bound skills Hermes has no workspace-relative skill discovery — it scans <HERMES_HOME>/skills first, then skills.external_dirs from config.yaml (verified against the bundled agent/skill_utils.py). The daemon wrote assigned skills to the generic .agent_context/skills/ fallback, which Hermes never reads, so they silently never took effect (#5242). When (and only when) an agent has skills bound, redirect HERMES_HOME to a minimal per-task compatibility overlay; a skill-less Hermes task keeps its real home and original behavior: - mirror every top-level entry of the shared home via symlink except the overlay-owned ones (denylist), reconciling entries deleted from the shared home; - derive a task-local config.yaml whose skills.external_dirs references the shared skills dir plus the user's existing external_dirs, expanded against the sanitized effective child env (unknown vars preserved, blocklisted keys resolved to the process value) and normalized to absolute paths; - write only the bound skills into the task-local skills/ dir (home skills scanned first, so they win); global skills are referenced, not copied; - keep memories/ overlay-owned (fresh per-task dir) AND disable the external memory.provider, so neither on-disk memory nor a shared backend crosses tasks; - keep active_profile/profiles out of the overlay so Hermes can't follow a sticky profile and redirect past it at startup. Profile handling mirrors hermes_cli.profiles: the daemon reads -p/--profile with agent.HermesProfileFromArgs and seeds the overlay from that profile's home via ResolveHermesSourceHome (default/invalid -> base, valid name -> <base>/profiles/ <name>, validated; a missing named profile fails closed). The profile flags are stripped from the acp argv ONLY when the overlay is active (hermesLaunchArgs), so a skill-less task's profile passes through unchanged. HERMES_HOME is no longer custom_env-blocklisted: no skills -> user value passes through; skills -> overlay overrides after layering. Fail closed — Prepare errors, Reuse returns nil. Task home 0700, derived config 0600 via atomic replace. Platform-native default home (%LOCALAPPDATA%\hermes, incl. the LOCALAPPDATA-missing fallback, on Windows). Tests span execenv/daemon/agent: no-skill no-op, child-env layering + env sanitization, profile parse/unquote + conditional strip + final args/env per scenario, custom/profile/default/invalid/missing/Windows source home, sticky- profile not mirrored, memory dir isolation + external provider disable, mirror reconciliation, external_dirs rebasing + sanitized/unknown-var expansion, local-precedence slug, perms, fail-closed, resume teardown. Docs (en + ja/ko/zh). Fixes #5242 * fix(hermes): make profile selection one resolver contract matching Hermes Round 5 review: the profile chain approximated Hermes' semantics in three separate places (argv parsing, source-home selection, arg filtering), so it diverged from native Hermes in several merge-blocking cases. Collapse it into one authoritative resolution: - agent.ParseHermesProfileArgs replaces HermesProfileFromArgs/ FilterHermesProfileArgs. It reproduces _apply_profile_override step 1/1b (first occurrence, value-flag skipping, `--` and `mcp add --args` boundaries, space-form profile-id guard) and returns the exact argv occurrence to consume; StripHermesProfileArgs removes only that occurrence. - execenv.ResolveHermesProfile replaces ResolveHermesSourceHome. It derives the Hermes root exactly like get_default_hermes_root (an already-profile-scoped HERMES_HOME roots at its grandparent), selects an explicit profile first, otherwise trusts a profile-scoped home (step 1.5) and only then the sticky <root>/active_profile (step 2), and validates via normalize/validate_profile_name (reserved hermes/test/tmp/root/sudo and empty inline `--profile=` are hard errors). Profiles always resolve under the root, so `-p default` re-roots and `-p <sibling>` is a sibling, never nested. - The daemon runs one parse + resolve, fails the task closed on a reserved/ invalid selection (matching Hermes' sys.exit(1)), and exports the selected source home as the effective env's HERMES_HOME so ${HERMES_HOME} in a profile's skills.external_dirs expands against the selected profile home (as native Hermes does before loading config.yaml), not the root or the overlay. Regressions added: root + sticky named profile selection; already-profile-scoped home with no flag; that home with -p default and -p <sibling>; reserved and empty inline profile values; and a selected profile whose external_dirs contains ${HERMES_HOME}. * fix(hermes): overlay-owned derived .env + symlink-resolved root Round 6 review, two remaining overlay-bypass paths: 1. A source `.env` could redirect HERMES_HOME after profile resolution. Hermes runs `_apply_profile_override()` then `load_hermes_dotenv()`, which loads `<HERMES_HOME>/.env` with override=True — so a mirrored source `.env` carrying an out-of-band `HERMES_HOME=` overwrote the overlay's home, repointing skill discovery and memory back at the source. `.env` is now overlay-owned and DERIVED (writeDerivedHermesEnv): it preserves the source's credentials/settings but strips any `HERMES_HOME` assignment and pins `HERMES_HOME` to the overlay last (single-quoted, literal), written 0600 via atomic replace. It is written even when the source has none, so Hermes' project-`.env` fallback (override=True only when no user `.env` loaded) can't relocate the home either. 2. Root derivation was lexical-only, diverging from `get_default_hermes_root`, which compares `env_path.resolve()` with `native_home.resolve()`. A HERMES_HOME symlinked into `<native>/profiles/<x>` was treated as its own root, so `-p default`/`-p <sibling>` resolved wrong. `hermesRootFromHomeFor` now resolves symlinks (Path.resolve(strict=False)-style best effort) for the containment decision while keeping the returned root unresolved, matching Hermes. Regressions: source `.env` with HERMES_HOME replayed through the override=True dotenv order (bound skill + task memory stay on the overlay; creds preserved); minimal overlay `.env` created when the source has none; and a symlinked profile home resolving `-p default`/`-p <sibling>` to the native root.
