+## Template Selection Guide
+
+**Use Framework template when:**
+- Introducing new model/system
+- Teaching actionable process
+- Want high saves (reference value)
+
+**Use Before/After template when:**
+- Have strong results to share
+- Building credibility
+- Want case study authority
+
+**Use Contrarian template when:**
+- Challenging assumptions
+- Positioning unique POV
+- Want engagement/debate
+
+**Use Failure template when:**
+- Building trust/authenticity
+- Sharing hard-won lessons
+- Want vulnerable connection

+# M0 — Implementation Log
+
+Running record of decisions, deviations, and out-of-scope follow-ups discovered
+during M0 execution. Plan: `docs/m0/plan.md` (18 steps). History → git; this file
+captures only what the commit messages cannot.
+
+## Session 3 — Steps 11–13 (2026-06-18)
+
+### Environment reality vs. plan assumptions
+
+The plan was authored assuming the operator's **real `.local.md` runtime data**
+sat in the plugin tree (227-line voice profile, analytics exports, draft queue).
+On this machine that data is **absent** — it is a clean clone:
+
+- `assets/voice-samples/`: only the PII-free placeholder `authentic-voice-samples.md`
+  (+ `.template.md`). No `.local.md` source.
+- `assets/drafts/`: only `.gitkeep`. `assets/analytics/`: only `README.md` + empty `ab-tests/`.
+- The 4 tracked D2 scaffold instances DO exist (`high-engagement-posts.md`,
+  `demographics.md`, `engagement-patterns.md`, `my-post-templates.md`).
+
+**Consequence for Step 12 (live migration):** every `MOVE_FILES` / `MOVE_DIRS`
+entry resolved to an absent source → clean no-op. Only the 4 `COPY_FILES`
+scaffolds were relocated. Result: `migrated — moved 0, copied 4, skipped 0`;
+`.migrated` marker written; idempotent re-run confirmed `already-migrated`.
+
+**Step 12 verify adapted:** the plan's literal check
+(`test -f .../voice-samples/authentic-voice-samples.md`) cannot pass without a
+`.local.md` source to move, so it was replaced with the achievable post-condition:
+`.migrated` marker present + 4 scaffolds external + `migrateData` wired into
+`session-start.mjs` + idempotency. The voice MOVE correctly no-op'd. (Operator
+pre-approved this adaptation before the run.)
+
+### OUT OF M0 SCOPE — git-history scrub of the leaked post (FOLLOW-UP)
+
+`assets/examples/high-engagement-posts.md` held the operator's **real** LinkedIn
+post at HEAD (the "Ralph Wiggum / vibe-coding" post — real names, real engagement
+metrics, real personal narrative). Step 13 scrubbed the **working-tree** content
+to a generic placeholder (0 `## Post N` sections → personalization score 0, no
+PII). **This does not remove the post from git history.** A history rewrite
+(`git filter-repo` / BFG) on `assets/examples/high-engagement-posts.md` is a
+separate, explicit operation — **deferred, not done here** (brief §13: out of M0
+scope). Track until the repo is published.
+
+### Note — external instance retains pre-scrub content (by design)
+
+The Step-12 migration copied `high-engagement-posts.md` to
+`~/.claude/linkedin-studio/examples/high-engagement-posts.md` **before** Step 13
+scrubbed the in-plugin file (B3 ordering). The external copy therefore still holds
+the migrated content. That is the operator's private data dir (outside any repo) —
+the operator may curate it; not an M0 concern.
+
+### D2 scaffolds completed
+
+All 6 scaffolds now have a read-only `*-template.*` seed: `case-study-template.md`
+and `framework-template.md` already shipped; Step 13 added the 4 missing ones
+(`high-engagement-posts-template.md`, `demographics-template.md`,
+`engagement-patterns-template.md`, `my-post-templates-template.md`). The 3
+already-generic instances seeded their templates verbatim; the high-engagement
+template is a freshly-authored generic seed (the old instance was the leak).
