+### S29b terminology-scrub — "thought leadership" → neutral (`agents/`)
+
+**CLASS: terminology-scrub** (NOT re-hardening — surgical removal of the operator-banned brand phrase
+"thought leadership", FORM A, from the agent surface; memory `no-thought-leadership-phrase`). Second
+sub-pass of the plugin-wide S29 scrub. SCOPE inherits the S29a 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 `agents/` = **15 in-file phrase
+occurrences / 7 files**; the 11 `thought-leadership-angles.md` filename pointers (hyphenated) are invisible
+to the space-grep and deferred to S29e. Read-and-show of all 15 in context before proposing the map.
+**Discovery during the header anchor-check (`grep "Value Test"`):** 2 same-class instances the phrase-grep
+missed because abbreviated — `trend-spotter.md:192/:257` "TL Value Test" (TL = Thought Leadership).
+Surfaced as an addendum (#16–#17), operator-approved BEFORE edit; scope not expanded silently.
+
+**HARDEN (17 edits, 6 files — 1:1).** Vocabulary consistent with S29a: "thought leadership angle(s)" →
+"content angle(s)"; "thought leadership" (positioning/practice) → "authority …"; the whole "Value Test"
+family → "Authority Value Test".
+- `strategy-advisor.md` (1): `:219` "Thought leadership and cross-platform visibility" → "Authority
+  building and …".
+- `content-planner.md` (1): `:24` "sustainable thought leadership growth" → "sustainable authority
+  building".
+- `voice-trainer.md` (1): `:24` "voice for LinkedIn thought leadership" → "… for LinkedIn authority
+  building".
+- `network-builder.md` (1): `:26` "compound their thought leadership reach and influence" → "compound
+  their authority, reach, and influence".
+- `differentiation-checker.md` (4): `:47` search query `"[topic]" thought leadership 2025 2026` →
+  `"[topic]" expert insights 2025 2026` (functional-keyword judgment-call, operator chose option b);
+  `:147` "marketing as thought leadership" → "marketing posing as expertise"; `:203` header "## Thought
+  Leadership Value Test" → "## Authority Value Test"; `:327` in-file "thought leadership test" → "authority
+  value test" (filename pointer `thought-leadership-angles.md` left for S29e).
+- `trend-spotter.md` (9): `:5` frontmatter desc "suggest thought leadership angles" → "suggest content
+  angles"; `:24` "establish thought leadership positioning" → "establish authority positioning"; `:33`
+  "strongest thought leadership angle per trend" → "strongest content angle …"; `:156` "map to the
+  strongest thought leadership angle" → "… content angle"; `:179` "Future Implication for thought
+  leadership" → "… for authority positioning"; `:334` "create thought leadership value" → "create
+  authority value"; `:344` "is the thought leadership" → "is the expertise"; `:192` header "### TL Value
+  Test" → "### Authority Value Test"; `:257` "Run TL Value Test" → "Run Authority Value Test".
+
+**VERIFY.**
+- Re-grep final FORM A `thought leadership` (space) in `agents/` → **NONE**; `\bTL\b` → **NONE**.
+- FORM B in `agents/` = **2**, unchanged (`analytics-interpreter.md:419` "(thought leader)",
+  `network-builder.md:562` "Thought Leader" search term).
+- Filename pointers `thought-leadership-angles.md` in `agents/` = **11**, unchanged (S29e).
+- 17 new replacement strings present (1:1 with edits).
+- `bash scripts/test-runner.sh` → `Passed: 81 · Failed: 0 · Warnings: 0`, **exit 0**; counts
+  **29/19/26/6** + v0.5.0 unchanged.
+- Disposition: **FIXED** (17 edits, 6 files). Commit `ebe56c5` (local; push parked per policy until operator OK).
+
+**SURFACED (queued, not swept).** `references/glossary.md:229` "### Thought Leadership Value Test" → its
+own directory pass **S29c** (temporary cross-directory naming gap until then — inherent to the
+per-directory design). `differentiation-checker.md:278` "### Value Test: [X]/3 passed" is already neutral
+(no FORM A / TL) and stays — consistent with the renamed header. Remaining S29 queue unchanged: **S29c**
+`references/` · **S29d** misc · **S29e** rename + 20 pointers.
