feat(harness): P1+P2+P3 harness optimization complete (VERSION 1.4.0)

Task 5  one-line registry descriptions on the 8 biggest skills (remediation-tool,
        gc-audit, packetdial, memory-dream, human-flow, self-check, impeccable,
        mailprotector); skill-description injection ~3320 -> ~2123 tokens (~36%),
        keyword triggers preserved, frontmatter valid.
Task 7  thinned /save + /sync bodies to point at sync.sh (single source) instead of
        re-documenting internals; Phase 0 save-vs-sync, cross-user notes, exit-75
        reporting kept verbatim; mechanical sync never depends on an LLM step.
Task 10 session-logs/YYYY-MM/ forward convention for new logs (scoped-grep recall,
        no monolithic index); existing flat logs untouched (grep covers both).
Bash    now-phoenix.sh helper (fixed UTC-7 epoch math; replaces unreliable
        TZ=America/Phoenix date that silently returns UTC on Git-Bash).

P0 (1.2.0) + Task 6 CLAUDE split + Task 9 delegation (1.3.0) already shipped.

 - **P0 COMPLETE (2026-06-08, VERSION 1.2.0).** Fleet broadcast sent.
-- NEXT — P1 context diet (Task 5a inventory -> Task 5 one-line descriptions -> Task 6
-  CLAUDE CORE/EXTENDED -> Task 7 thin save/sync). Then P2 delegation re-tune, P3 knowledge.
-- Promote the warn-only guard (Task 4) to FATAL after a clean warn window (check
-  `.claude/harness/guard.log` across the fleet).
+- [DONE] Task 6 — CLAUDE.md split: lean CORE (~1.2k tokens, was ~4.9k) + `CLAUDE_EXTENDED.md`
+  (full original preserved verbatim). All safety-critical rules retained in CORE (v1.3.0).
+- [DONE] Task 9 (P2) — delegation re-tune folded into CORE: act-directly-by-default; delegate
+  only for (a) high-volume output, (b) blast radius >3 files across layers, (c) domain shift,
+  (d) parallel. Single-agent-for-coupled-tasks kept.
+- [DONE] Task 5 — one-line registry descriptions on the 8 biggest skills (remediation-tool,
+  gc-audit, packetdial, memory-dream, human-flow, self-check, impeccable, mailprotector);
+  skill-description injection ~3320 -> ~2123 tokens (~36% cut), keyword triggers preserved,
+  frontmatter still valid.
+- [DONE] Task 7 — thinned `/save` + `/sync` command bodies: they now point to `sync.sh` as the
+  single source instead of re-documenting its internals; load-bearing LLM-judgment parts (Phase 0
+  save-vs-sync, cross-user note display, exit-75 reporting) kept verbatim. Mechanical sync never
+  depends on an LLM step.
+- [DONE] Deterministic Bash fixes (from the "deferred to separate spec" carve-out): `now-phoenix.sh`
+  helper added (fixed UTC-7 epoch math — no `TZ=America/Phoenix` Git-Bash bug); `post-bot-alert.sh`
+  already builds JSON via `jq -nc --arg` (verified). Full Python port remains a separate future spec.
+- [DONE] Task 10 (P3) — knowledge tiering: recall order already in CORE (wiki -> CONTEXT/log ->
+  coord); adopted `session-logs/YYYY-MM/` as a FORWARD convention for new logs (verified: nested
+  path still matches the Phase 0 log-detection grep and wiki slug derivation). Existing flat logs
+  left in place — recall grep covers both layouts; NO mass migration (would break wiki `source_logs`
+  refs for low payoff).
+- **P1+P2+P3 COMPLETE (2026-06-08, VERSION 1.4.0).**
+- REMAINING (ops follow-ups, not blocking):
+  - Promote the warn-only guard (Task 4) to FATAL after a clean warn window (check
+    `.claude/harness/guard.log` across the fleet).
+  - Schedule `memory-dream --apply-safe` per-machine (deliberate per-box ops setup; default is
+    read-only/proposals, so unattended --apply-safe is a judgment call left to the operator).
+  - Optional later: migrate existing flat session-logs into month folders if/when the flat dir
+    becomes unwieldy (low priority; grep recall already covers both).
+  - Task 8 (shard big command bodies) stays DEFERRED per Grok/Gemini.
