 A [Claude Code](https://docs.anthropic.com/en/docs/claude-code) plugin for deep implementation planning, multi-source research, autonomous execution, independent post-hoc review, and zero-friction multi-session resumption. Six commands, one pipeline:
 
-> **What's new in v5.6.0 — `/trekexecute` loop hardening** — execution-loop termination is now **machine-verifiable** and recovery is **bounded by an explicit budget**:
-> - **Machine-verifiable completion gate** — a session reports `completed` only when the Phase 7.5 manifest audit PASSes, the stop signal exits 0, and the success criteria are green (**Hard Rule 18**, promoted from prose to an enforced stop-signal contract anchored in the audit, not the model's self-assessment).
-> - **Bounded recovery** — a global `TREKEXECUTE_MAX_RECOVERY_ITERATIONS` budget (default **25**, env-overridable) sits atop the per-step caps as a three-axis cap hierarchy (**Hard Rule 20**), with an `iterations_remaining` signal in the progress + summary JSON and a deterministic cross-check that catches a never-decremented counter.
-> Additive — no breaking change. Full detail in [CHANGELOG.md](CHANGELOG.md).
->
-> **What's new in v5.5.0 — brief framing enforcement (`brief_version 2.2`) + narrow wins** — `/trekbrief` now opens with a **framing declaration** (Phase 2.5): every brief records `framing: preserve | refine | replace | new-direction` *before* any prose is written, so the plan can't quietly polish a wrong premise. Three version-gated layers ship at `brief_version ≥ 2.2`:
-> - **Framing field** — a required `framing` enum in frontmatter; enum-checked on any version, and a missing value at `≥ 2.2` is a blocker. Collected in Phase 2.5 before prose, non-skippable even in `--quick`.
-> - **Memory alignment** — a new `brief-reviewer` dimension compares the brief's Intent/Goal + framing against operator memory and flags *explicit* contradictions (a no-op that scores N/A when no memory is supplied).
-> - **Obligatory `## TL;DR`** — a ≤ 5-line, framing-anchored summary at the top of every brief, so a wrong premise is caught at a glance.
-> Existing `2.0`/`2.1` briefs stay valid (forward + backward compatible), mirroring the `phase_signals ≥ 2.1` gate. This is a **schema-axis** change — the plugin version badge bumped to **v5.5.0** at this coordinated release; see [docs/HANDOVER-CONTRACTS.md](docs/HANDOVER-CONTRACTS.md) §Handover 1 for the contract evolution.
-> **Also in v5.5.0:** a reviewer-output **schema contract** for `/trekreview` (validates each reviewer's JSON, re-asks on schema failure); an opt-in **`--workflow`** path for `/trekreview` Phase 5–6 (bake-off POSITIVE; default stays prose to preserve the 2.1.154+ portability floor); **Opus 4.8** baseline with native `effort:` on 8 agents; exec-form hooks + enforced `disallowed-tools` on `/trekexecute`. Full arc in [CHANGELOG.md](CHANGELOG.md).
->
-> **What's new in v5.1.1** — Remediation patch closing 11 of 12 findings from the v5.1.0 review (SC8 dogfood gate scheduled for sesjon 8). Lukker:
-> - **Bug fixes (load-bearing):** YAML-number bypass in `brief-validator` (#8) + doc-consistency pin lock-in (#11) so the gate fires for both quoted and unquoted `brief_version`.
-> - **Wiring:** `phase-signal-resolver` helper wired into all 4 downstream commands (#9) with TDD pair `resolvePhaseModel` + profile-resolver non-interference test (#4 SC5); `brief-validator` gate required uniformly in `/trekresearch` + `/trekexecute` (#12).
-> - **Test refactor:** runtime SC1 walk for trekbrief (#1) + per-tier resolver-output + missing-signals falsification for `/trekplan`/`/trekresearch`/`/trekreview`/`/trekexecute` (#2 #3 #6 #10) + dedicated SC5 test (#7).
-> - **Documentation:** Dogfood-gate scheduling in REMEMBER (#5, sesjon 8 manual) + Decision B high-effort behavior per command + brief Non-Goal/SC1 amendments + coordinator high-effort normalization.
-> v5.1.1 is additive — no breaking changes against v5.1.0.
->
-> **What v5.1 introduced** — `/trekbrief` Phase 3.5 commits per-phase `phase_signals` (effort + optional model for `research`/`plan`/`execute`/`review`) to `brief.md` frontmatter. `brief_version: 2.1` activates a validator-side sequencing gate (`BRIEF_V51_MISSING_SIGNALS`) so downstream commands halt with a friendly hint when signals are missing. Composition rule per downstream command: brief signal wins per-phase, profile fills gaps. `effort == low` activates the existing `--quick`-equivalent code-path in each command (`/trekexecute` low-effort = `--gates open` + sequential). Additive — no breaking changes; pre-2.1 briefs still validate.
+> **What's new — v5.6.0: `/trekexecute` loop hardening.** Execution-loop termination is now machine-verifiable (completion gate, Hard Rule 18) and recovery is bounded by an explicit `TREKEXECUTE_MAX_RECOVERY_ITERATIONS` budget (default 25, Hard Rule 20). The prior coordinated release **v5.5.0** added brief **framing** enforcement (`brief_version 2.2`) + a `/trekreview` reviewer-schema contract. Additive — no breaking changes. **Full version history → [CHANGELOG.md](CHANGELOG.md).**
