Register WP-0007 (Distribute), WP-0008 (Read-before-Edit), WP-0009 (Measure)

Three workplans queued and registered with the State Hub (via REST — MCP write
layer is erroring this session):
- AGENTIC-WP-0007 Phase 3 Distribute: per-flavor distributor adapters render
  approved catalog patterns into proposed (HITL) artifacts, scoped by repo/domain.
- AGENTIC-WP-0008 Read-before-Edit reflex: act on the #1 friction finding.
- AGENTIC-WP-0009 Phase 4 Measure: baseline + before/after effectiveness + trend.
Proceeding in that order.

+# Coding Session Memory — Phase 3 (Distribute)
+
+Implements **Distribute** (PRD §6.4, FR-X1–FR-X4), continuing
+[AGENTIC-WP-0004](AGENTIC-WP-0004-session-memory-phase2.md) (Curate). Distributor
+adapters render the **approved / `distribution_ready`** SolutionPatterns from the
+Pattern Catalog into per-flavor artifacts, using the `rendering_hints` produced in
+Phase 2. Mirror image of the collector design: **agnostic core, thin adapters at
+the edges** (FR-A2) — adding a flavor = one collector + one distributor.
+
+Key boundary (FR-X3): output is **proposed, not auto-applied** — artifacts are
+written as reviewable proposals (HITL), scoped by repo/domain (FR-X2), with an
+active-pattern registry tracking which patterns are live where (FR-X4).
+

+```
+
+Define a `Distributor` protocol and an `Artifact` dataclass (flavor, target_path,
+content, pattern_id) in `session_memory/distribute/`. `render(pattern, scope)`
+reads the agnostic `SolutionPattern` plus its per-flavor `rendering_hints`; base
+helpers handle idempotent snippet markers. Agnostic core; flavor logic only in
+adapters. Unit-tested.

+
+`distribute/claude.py`: render an approved pattern into a `CLAUDE.md` snippet block
+(or skill stub) with stable `BEGIN/END` markers so re-distribution updates in
+place rather than duplicating. Uses `rendering_hints["claude"]`. Unit-tested.

+```
+
+`distribute/codex.py` (`AGENTS.md` snippet) and `distribute/grok.py` (native
+instruction format), each rendering the *same* agnostic pattern via its
+`rendering_hints`. Confirms FR-A3: a pattern discovered via one flavor is
+expressible for all. Unit-tested.

+```
+
+Filter patterns by `Scope` (repos/domains/flavors) so a pattern only lands where it
+applies (FR-X2). Write artifacts as **proposals** under a `proposals/` dir, never
+auto-applied (FR-X3, HITL). Track which patterns are active in which environments
+in an active-pattern registry (FR-X4). Unit-tested.

+# Act on #1 Friction — Read-before-Edit Reflex
+
+The error-body mining ([AGENTIC-WP-0006](AGENTIC-WP-0006-error-body-mining.md))
+found that the single most common error across real coding sessions is
+**`File has not been read yet. Read it first before writing to it.`** — Edit/Write
+before Read, in **12 of 27 sessions across 8 repos** — followed by the stale-read
+**`File has been modified since read`** (6 sessions). See
+[ASSESSMENT-infra-friction.md](../docs/ASSESSMENT-infra-friction.md).
+
+This is the cheapest high-value fix surfaced by the whole analysis: a short
+behavioural reflex in the agent instructions. We also capture it as a curated
+SolutionPattern so Phase 3 Distribute can propose it to other repos/flavors —
+closing the assess → curate → distribute loop by hand for one real pattern.
+
+## Add Read-before-Edit Reflex to Agent Instructions

+state_hub_task_id: "549c84c1-5bd8-4ff6-b61d-1c72946b8b8e"
+```
+
+Add a concise, data-cited **Read-before-Edit / re-read-on-"modified since read"**
+reflex to `AGENTS.md` (and note for `CLAUDE.md`), targeting the #1 and #2 recurring
+errors. Keep it short to avoid context bloat (cf. PRD OQ6 — pattern bloat degrades
+context budgets).

+```
+
+Promote the recurring "file not read" problem into a curated `SolutionPattern` in
+the Pattern Catalog with per-flavor `rendering_hints`, so Phase 3 Distribute can
+render and propose it across repos/flavors. Links assess → curate → distribute end
+to end on a real pattern. After updates, notify the operator to run
+`make fix-consistency REPO=agentic-resources`.

+# Coding Session Memory — Phase 4 (Measure)
+
+Implements **Measure** (PRD §6.5, FR-M1–FR-M3) — the loop-closer. After patterns
+are distributed (Phase 3) and changes land (e.g. the State Hub skill
+[STATE-WP-0058] and the Read-before-Edit reflex
+[AGENTIC-WP-0008](AGENTIC-WP-0008-read-before-edit-reflex.md)), Measure answers:
+**did it actually help?**
+
+Reuses what is already captured — WP-0005 tool buckets, WP-0006 error mining — so
+this is computation over existing digests, not new capture.

+(infra-overhead share, error rate, recurring-error count, schema-thrash, cost

+Given a change/pattern with an applied-at date, compare sessions **after** it
