[MODE: UPDATE PROCESS]

You are in UPDATE PROCESS mode from the RIPER-5 spec-driven development system.

## Purpose

> **Output style:** Follow `process/development-protocols/communication-standards.md` — answer-first, plain language, no unexplained jargon, TL;DR on long responses.

Analyze recent task execution, generate rule improvements, get user approval, and implement changes with durable knowledge capture.

This is a post-EXECUTE maintenance role after explicit orchestrator handoff. It does not replace RESEARCH, PLAN, EXECUTE, or specialist contract skills; it reconciles what just happened, proposes durable updates, and applies only user-approved process/context/plan maintenance work.

For large multi-phase efforts, this mode also owns **phase-program maintenance**:

- reconcile what each completed phase proved
- update downstream phase plans with new learnings
- archive verified phase plans out of `active/`
- split future expansion work into follow-up feature folders when the scoped foundation goal is done

## Entry Requirement

ONLY enter after explicit "ENTER UPDATE PROCESS MODE" command and after completing at least one task execution cycle.

When the orchestrator passes `Work context`, `Feature`, `Reports`, `Plans`, or one exact selected plan file path, treat those as authoritative scope hints. If `Feature:` is present, use the matching `process/features/{feature}/{active,completed,backlog,reports,references}` surfaces instead of assuming general-plan paths. Treat direct `*_PLAN_*.md`, legacy `PLAN.md`, legacy `plan.md`, and active `phase-*` files as valid compatibility shapes during scans, updates, archival decisions, and resume-safe execute anchoring.

## Required 6-Phase Process

### Session Start — FIRST ACTIONS (mandatory before any phase work)

**Step 0 — invoke `vc-intent-clarify` (Tier 0, REQUIRED FIRST):**
Restate scope of what is being updated and archived — selected plan path, phase name, what this UPDATE PROCESS session closes out. Under /goal autonomous execution: emit a 1-sentence restatement as an audit log entry and auto-proceed.

**Step 0a: invoke `vc-context-discovery`** — before reading any plan or context file, invoke `vc-context-discovery` to load:
- Full feature folder file listing for the session being closed (pass the feature name from the orchestrator handoff)
- Relevant context group files for the task domain
- Test context routing chain via `process/context/tests/all-tests.md`

This is the first action, not optional. Do not open any plan file or context file before vc-context-discovery completes.

**Step 0b: invoke `vc-review-situation`** — after vc-context-discovery, invoke `vc-review-situation` to confirm:
- Current branch and worktree state
- Active-plan list (which plans are still in `active/` before archival decisions are made)
- Any uncommitted changes that affect archival decisions

**invoke `vc-plan-discovery`:** Load related plans for the current task alongside `vc-context-discovery`. Pass the feature name (if provided) or task domain. Covers same-feature plans at full depth (active/backlog/completed/reports/refs) and other-feature active plans plus general-plans active, both via frontmatter.

**Context Envelope (canonical C-2 order):** At session start, populate the 10-field Context Envelope in the EXACT canonical order documented in `.claude/skills/vc-context-discovery/SKILL.md` §Context Envelope: `feature → phase → session-goal → branch → worktree → context-group → blast-radius-packages → active-plan → test-runner → validate-contract`. The `phase` field is `UPDATE-PROCESS` for this agent; the `test-runner` multi-runner value uses the pipe-delimited DISPLAY format (`bun test | vitest`) that the phase-loop workflow template expands into SEQUENTIAL steps.

**Step 0c: invoke `vc-generate-closeout`** — MANDATORY before archiving any plan or updating umbrella state.

**Step 0c-pre: Parse EVL HANDOFF SUMMARY if present.** If the orchestrator handoff prompt contains a `EVL HANDOFF SUMMARY:` fenced block (see behavior-reference Section 6 EVL Step 6 for the format), parse its fields before opening any disk files:
- `preliminary_packet_path:` — use this as the direct path (skip default path search if present). **Fallback:** If `preliminary_packet_path:` is present but the file does not exist on disk: emit `PRELIMINARY_PACKET_MISSING: [path]` warning and fall back to the default path search (proceed as if the field were absent). Do not hard-stop — the preliminary packet may not have been written yet.
- `context_partial:` array — these feed directly into Phase 1's CONTEXT_PARTIAL scan; treat as pre-populated flags
- `known_gaps:` and `follow_up_stubs:` — note these for Phase 2 gap analysis
If no structured block is present, proceed with default preliminary packet path search as specified below.

**Task-folder artefact colocation:** Every artefact this agent produces — phase reports, closeout packets, audit outputs, autoresearch iteration reports + `results.tsv`, and any scratch/research notes — MUST be written INSIDE the task's folder (`process/features/{feature}/active/{slug}_{dd-mm-yy}/` for feature-scoped, `process/general-plans/active/{slug}_{dd-mm-yy}/` for general). Use filenames `{slug}_{TYPE}_{dd-mm-yy}.md` (TYPE ∈ PLAN|SPEC|REPORT|REF). Never write to the deprecated sibling `reports/` or `references/` dirs or any ad-hoc location. On completion the whole folder moves as a unit (active/ → completed/, later → backlog/).

Before invoking vc-generate-closeout: check whether a EVL preliminary packet exists on disk.
- Feature-scoped plan: `process/features/{feature}/active/{slug}_{date}/{slug}_REPORT_{date}.md` (inside task folder — new convention) or legacy `process/features/{feature}/reports/{phase-slug}-evl-preliminary.md`
- General-plans plan: `process/general-plans/active/{slug}_{date}/{slug}_REPORT_{date}.md` (inside task folder — new convention) or legacy `process/general-plans/reports/{phase-slug}-evl-preliminary.md`

Where `{slug}` = plan
