+### S29c terminology-scrub — "thought leadership" → neutral (`references/`)
+
+**CLASS: terminology-scrub** (NOT re-hardening — surgical removal of the operator-banned brand phrase
+"thought leadership", FORM A, from the reference-doc surface; memory `no-thought-leadership-phrase`).
+Third and largest sub-pass of the plugin-wide S29 scrub (~2× the S29a/S29b volume). SCOPE inherits the
+S29a/S29b operator-lock verbatim (FORM A only; FORM B untouched; per-directory sub-pass, map approved
+before edit).
+
+**TEST (tool-grounded).** `grep -in "thought leadership"` (space) in `references/` = **35 phrase lines /
+15 files** — 29 single-line across 14 files + the canonical `thought-leadership-angles.md` = 6 lines / 7
+instances (line 7 ×2) ≈ **36 FORM A instances**. The 3 hyphenated `thought-leadership-angles.md` filename
+pointers are invisible to the space-grep and deferred to S29e. Read-and-show of every occurrence in
+context before proposing the 34-row map. Anchor-check (`grep "Value Test"` / `#thought-leadership` /
+`#the-standard-thought`): **no anchor links** to the changed headers anywhere in the plugin, and the only
+"Value Test" / "Standard Thought Leadership Structure" term-hits were the two SSOT spots being edited — no
+hidden same-class instances.
+
+**S29e filename locked (operator, this session): `thought-leadership-angles.md` → `content-angles.md`.**
+The canonical file's in-file title/headers were therefore scrubbed now for consistency (H1 →
+"# Content Angles"; "## The Authority Value Test"; "### Step 3: Test For Authority Value"); the file
+rename + all 20 pointers remain S29e (atomic).
+
+**HARDEN (34 edits, 15 files — 1:1).** Vocabulary consistent with S29a/S29b: "thought leadership
+angle(s)" → "content angle(s)"; "thought leadership" (positioning/practice) → "authority …"; content-type
+labels (lists/tables) → "authority content / authority posts"; the "Value Test" family → "Authority Value
+Test".
+- Established cross-pass equivalents closed: `glossary.md:229` "### Thought Leadership Value Test" →
+  "### Authority Value Test" (closes the S29b cross-directory naming gap); `glossary.md:29` "8 universal
+  thought leadership angles" → "content angles"; `engagement-frameworks.md:137` "Standard Thought
+  Leadership Structure" → "Standard Post Structure" (matches S29a `post:98`).
+- `thought-leadership-angles.md` (6 edits / 7 instances): H1 → "# Content Angles"; :3 "identifying
+  thought leadership angles" → "content angles"; :7 (×2) "Thought leadership isn't about…/can become
+  thought leadership" → "Authority isn't about…/can build authority"; :92 "Test For Thought Leadership
+  Value" → "Test For Authority Value"; :212 "Marketing disguised as thought leadership" → "expertise";
+  :215 "## The Thought Leadership Test" → "## The Authority Value Test".
+- `linkedin-formats.md` (5): :24/:79/:272/:309 content-type labels → "authority content/posts"; :295
+  "Text-based thought leadership often outperforms…" → "Text-based content …" (avoids authority…authority
+  echo).
+- `linkedin-visual-style.md` (4): :3 "For thought leadership," → "For building authority,"; :7 "thought
+  leadership niche" → "authority niche"; :82 label → "authority content"; :123 "myth for thought
+  leadership content" → "authority content".
+- `trajectory-strategy-adjustments.md` (3): :167 "Shift to thought leadership" → "authority content";
+  :202 "100% thought leadership and signature content" → "100% authority and signature content"; :217
+  "thought leadership deepening" → "authority deepening".
+- `linkedin-monetization-strategies.md` (3): :285 "Inbound from thought leadership" → "authority
+  building"; :624 "80% thought leadership" → "authority content"; :658 "Breaks the thought leadership
+  positioning" → "authority positioning".
+- `ai-content-framework.md` (2): :3 "build thought leadership in the AI space" → "authority"; :380 "main
+  LinkedIn thought leadership skill" → "content skill" (judgment-call; avoids awkward "authority skill").
+- Single-edit files (8 edits / 8 files): `ab-testing-framework.md:9` → "authority building";
+  `growth-roadmaps.md:222` "Thought leadership pieces" → "Authority pieces";
+  `linkedin-growth-playbook-2025-2026.md:822` → "Reflective authority content";
+  `algorithm-signals-reference.md:158` (SSOT) "Text for thought leadership" → "Text for authority"
+  (phrase only; magnitudes = S30); `scheduling-strategy.md:35` → "Mid-week authority content";
+  `poll-strategy-guide.md:179` "thought leadership angle" → "content angle"; `video-strategy-guide.md:3`
+  → "authority content"; `video-strategy-guide.md:580` "8 thought leadership angles" → "8 content
+  angles".
+
+**KEPT BY DESIGN (operator-approved).** `video-strategy-guide.md:429` ironic quote "Your 'thought
+leadership' content isn't leading anyone's thoughts." — scrubbing destroys the point.
+`video-strategy-guide.md:532` "TL;DW" = false positive (too long, didn't watch).
+
+**VERIFY.**
+- Re-grep final FORM A `thought leadership` (space) in `references/` → only the kept ironic quote
+  (`video-strategy-guide.md:429`); canonical-file in-file FORM A → **NONE**.
+- FORM B in `references/` = **4**, unchanged (`collaborations-guide.md:211`, `analytics-tools-guide.md:227`,
+  `opportunity-generation.md:81`, `linkedin-visual-style.md:134`).
+- Filename pointers `thought-leadership-angles.md` in `references/` = **3**, unchanged (S29e).
+- New terms present: "Authority Value Test" (`glossary.md:229` + `thought-leadership-angles.md:215`,
+  consistent), "Standard Post Structure" (`engagement-frameworks.md:137`).
+- `bash scripts/test-runner.sh` → `Passed: 81 · Failed: 0 · Warnings: 0`, **exit 0**; counts
+  **29/19/26/6** + v0.5.0 unchanged.
+- Disposition: **FIXED** (34 edits, 15 files). Commit `b9b769c` (local; push parked per policy until
+  operator OK).
+
+**SURFACED (queued, not swept).** Remaining S29 queue: **S29d** `skills/` + `config/` + `assets/` +
+`README.md` + `CLAUDE.md` + `hooks/prompts/` + forward-looking docs + test `.mjs` · **S29e** rename
+`thought-leadership-angles.md` → `content-angles.md` + all 20 pointers (atomic; filename locked). The
+canonical file's in-file phrase scrub is done, so S29e is now a pure rename + pointer-update with no
+remaining FORM A inside the file.
