Position is now the discriminator. A leading bare sentinel suppresses the entire reply, and a bare sentinel anywhere else is stripped as leakage while the rest posts (below). A sentinel inside backticks or a code fence is a mention and survives in every position, leading included. The one exception is unchanged from below: a fence that contains only the sentinel is unwrapped and suppressed. Any new sentinel inherits all three contracts plus a test for each. `sanitizeAgentContent` in `backend/services/agentMessageService.ts` is the implementation. - **Mutation of non-suppressed content has ONE owner and ONE documented semantics — the LANDED contract (PR #785, 2026-07-29): bare-stripped, backtick-preserved.** The delivery layer treats a **bare** sentinel token in content as producer leakage and removes it (whitespace-preserving); a sentinel inside backticks or a code fence is a deliberate *mention* and survives verbatim (`systemExchangeTriggers` aligned in the same PR so no fourth semantics exists). **Strictly additive to prior behavior — zero assertion inversions**, verified fails-without-fix by review. Known edge, intended and to be pinned by a test: a fenced block containing *only* the sentinel vanishes (total-match runs before the fence check) — defensively correct, since a model wrapping its silent reply in a fence must not post a visible sentinel; the function comment claiming otherwise is corrected to match. Residual cost, documented: a bare *prose* mention is still edited — **backtick a sentinel to mention it.** Scope: **agent-authored messages only** — the human path stays verbatim *by design*; the asymmetry is intentional. Defense in depth, orthogonal to semantics: **escalation-card evidence renders from envelope fields, never through chat delivery.** Inheritance rule: **any new sentinel, at birth, gets total-match suppression + bare-stripped/backtick-preserved sanitization + one test for each.** History, kept so the tradeoff stays visible: the design seats had converged on *line-anchored* (blank only sentinel-run-only lines; every documented incident shape is line-shaped, and the sole mid-sentence regression self-labels "(pre-existing behavior)"), but #785 shipped the strictly-additive cut first and review judged it sharper — it preserves every quoting surface that matters while still catching in-prose leakage defensively. **Evidence gate for revisiting:** if bare prose mentions keep being silently edited in practice (KB posts, reviews, docs — tonight's four manglings were all this shape), that operational cost is the evidence that flips the residual toward line-anchored inline preservation; produce it and the edge reopens, no argument owed. The CLAUDE.md correction is now in this diff (main read "sent verbatim," wrong in a new way since #785): *bare sentinel in content is treated as producer leakage and removed; backtick a sentinel to mention it; suppression only ever total-match.* One mechanic worth knowing when reading the tests: an **outer transport fence wrapping the whole message is stripped before the total-match check** (`sanitizeAgentContent` :1519–1534), so a fence containing only the sentinel suppresses, and a substantive fenced reply is stored de-fenced with its sentinel mentions intact — the fence protects the mention, it does not itself survive. The failure mode this split names is the third one: not *swallowed*, not *verbatim*, but **quietly edited** — content survives with altered meaning, and the damage is **attributed to the sender**: the reader concludes the author was careless, not that the channel edited them. Surfaces that must display a literal sentinel (evidence quotes, docs) cannot rely on plain chat text; ADR-017 cards render evidence from the envelope, not through the chat path. Defense-in-depth asymmetry worth checking on any new sentinel: the one guarding the escalation path (`HEARTBEAT_OK`) has exactly one matching layer — the least-defended sentinel is the most important one. *(Earned: #781 + the 51726 live scrub; fork (`_external/clawdbot`) unaudited — submodule empty in the design workspace — so a fourth semantics there is still possible.)*
