All 39 vault notes mentioning an 'embedding false friend' verdict were read and classified (object-level false friend / meta-level false friend / confirmed-or-hedged bridge / domain-level / tangential mention) and cross-checked against this hub's tracking lists. Result: tracking is complete — every false-friend verdict is registered, and every confirmed/hedged bridge is correctly tracked as a bridge rather than a false friend. No omission remained after the same-day kelly-luccioni fix. See the dated reconciliation line at the end of the changelog."

The error of assuming that two things sharing a name share a nature — tests or phenomena carrying the same label while measuring different underlying constructs. Edward L. Thorndike used the name "jingle" for the error in 1904, attributing the term itself to [[entity-herbert-austin-aikins|Herbert Austin Aikins]] rather than coining it (see the 2026-09-17 changelog entry below); psychologist Truman Lee Kelley named its mirror in 1927 — the jangle fallacy, different names hiding the same construct — and the pair has travelled together since.

Matters to this vault as the general name for the failure mode behind a recurring class of false bridges the embedding-search layer produces — two claim-notes cosine-paired on shared vocabulary that turns out to gate two different mechanisms, as already logged in [[observation-ml-ad-en-gedi-cosine-pairing-is-embedding-false-friend]] and [[observation-hawks-jeffress-cosine-pairing-is-embedding-false-friend]]. The 2026-08-11 capture that introduced the term to the vault used it with a twist: not just a fallacy the vault's own retrieval commits, but a fallacy that two academic fields (neural-network catastrophic forgetting and econometric organizational forgetting) each independently caught and corrected inside their own literature, unaware the other had done the same.

Sourced here to Wikipedia's definitional entry (Tier 4, per `sources.md`'s allowance for uncontested definitional claims) plus, for the attribution, Elson et al., "Detecting jingle and jangle fallacies by identifying consistencies and variabilities in study specifications" (PMC11393684, Tier 1–2), which credits the jingle fallacy to Thorndike (1904, p. 14) and the jangle fallacy to Kelley (1927, p. 64). Neither Thorndike's 1904 text nor Kelley's *Interpretation of Educational Measurements* has been directly read by the vault.

**Correction history.** 2026-08-13 (cross-model audit, claude-opus-5) — this page previously read "coined by psychologist Truman Lee Kelley in 1927," following Wikipedia's compressed attribution of both terms to Kelley. Corrected to Thorndike (1904) for *jingle*, Kelley (1927) for *jangle*; prior wording preserved in this line. The same error was corrected in [[observation-catastrophic-and-organizational-forgetting-converge-on-jingle-fallacy-correction]] in the same pass.

- 2026-08-15: a second instance of the pattern, previously unlinked here — Brooks's 1991 and Dreyfus's 2002 identically-titled "Intelligence without representation" papers share a full-title jingle (tighter than the forgetting pair's single shared word), tested against both papers' reference lists and found empty in both directions. See [[observation-brooks-dreyfus-title-echo-is-an-untagged-jingle-fallacy-instance]].
- 2026-08-16: [[observation-gates-jevons-cosine-pairing-is-embedding-false-friend]] (2026-08-14) is confirmed as the fourth "embedding false friend" instance — uncontested, after a candidate fourth (the 2026-07-23 DCA/IB pairing) resolved toward "genuine bridge" instead and dropped out of the count. This crosses the hub threshold [[observation-ml-ad-en-gedi-cosine-pairing-is-embedding-false-friend]]'s own commentary set ("it gets one more before I trust it"); see [[observation-gates-jevons-is-fourth-confirmed-embedding-false-friend-instance]]. Separately, a bipartite hop one level up found that the 0.90 cosine pairing *between* the ML/AD-En Gedi and Gates-Jevons observation notes themselves is not a fifth false-friend instance but a confirmed bridge — their shared authorial scaffolding is real because their referent (the diagnostic act itself) is the same; see [[observation-ml-ad-en-gedi-and-gates-jevons-false-friend-notes-are-a-confirmed-bridge]] (capture 2026-08-16-bipartite-two-things-this-vault-knows-in-different).
- 2026-08-20: a second meta-level bipartite hop, this time between Gates-Jevons and [[observation-rhw-1986-werbos-docsub-cosine-bridge-is-thematic-not-causal]] (never a member of this hub's false-friend list), broke the binary the 2026-08-16 hop set up — same authorial scaffolding as the confirmed bridge above, but grounding that does not converge (no shared citation of the cosine-arbitrariness paper), so the pairing is neither a clean bridge nor a clean false friend. See [[observation-rhw-docsub-gates-jevons-meta-pairing-is-a-hedged-bridge]] (capture 2026-08-20-bipartite-two-things-this-vault-knows-in-different).
- 2026-08-22: a third-order hop — the first between two notes that are each already syntheses rather than object-level verdicts — compared the 2026-08-16 fourth-instance note against the 2026-08-20 hedged-bridge note (cosine 0.87) and found a third species of confirmed bridge: not a shared-diagnostic-referent (2026-08-16's kind) but a citation-genealogy dependency, since the hedged-bridge note's own contrast leans on the fourth-instance note's specific finding, cited via this hub's changelog rather than by direct wikilink. See [[observation-gates-jevons-fourth-instance-hedged-bridge-pairing-is-citation-genealogy-bridge]] (capture 2026-08-22-what-genuinely-connects-gates-jevons-is-the-vaults).
- 2026-08-27: a domain-level instance outside the embedding-retrieval subtype entirely — no cosine pairing produced this one. Merton's sociology-of-science concept "obliteration by incorporation" and the vault's own coined "citational narrowing" (Song Jian cluster) share a description (a name drops out of later citation) but gate opposite mechanisms (erasure by over-success vs. erasure of a dissenter by narrative compression), surfaced by hand while searching for a formal theory to match the vault's own coinage. See [[observation-obliteration-by-incorporation-and-citational-narrowing-are-a-false-friend]].
- 2026-08-25: a fourth-order hop, and the first to reach outside the Gates-Jevons chain — compared [[observation-puckette-dataflow-claims-confirmed-bridge-not-false-friend]] (2026-08-14) against the 2026-08-22 citation-genealogy note (cosine 0.87) and found a fourth species: neither citation-genealogy nor shared-diagnostic-referent, but a **buried common-ancestor bridge** — the 2026-08-16 capture had already named the Puckette pairing as a member of this lineage twice, and neither mention survived into a promoted note or this hub until now. See [[observation-puckette-gates-jevons-fourth-instance-pairing-is-buried-common-ancestor-bridge]] and, for the dropped-mention finding itself, [[observation-2026-08-16-capture-dropped-two-puckette-lineage-mentions-before-promotion]] (capture 2026-08-25-what-genuinely-connects-the-puckette-dataflow-pairing-is).
- 2026-08-29: [[observation-liang-1979-olsder-1975-cosine-pairing-is-embedding-false-friend]] (2026-08-26), previously omitted from this hub, is registered as a fifth object-level "embedding false friend" instance — its own verdict paragraph explicitly reaches the same grounding claim ([[claim-cosine-similarity-of-embeddings-can-be-arbitrary]]) as the other four, by in-body wikilink rather than frontmatter citation. The same session ran a fifth meta-level bipartite hop, pairing that note against Gates-Jevons (cosine 0.87) and finding a second **confirmed bridge** — same species as the 2026-08-16 case (shared grounding document, two routes to it), looser texture (diverging `audit_status` scaffolding, "dissolve" appears in only one note). See [[observation-gates-jevons-liang-1979-olsder-1975-cosine-pairing-is-confirmed-bridge]] (capture 2026-08-29-what-genuinely-connects-the-vaults-cosine-087-proximity).

- 2026-08-31: a sixth meta-level hop, and the first to reach outside the Gates-Jevons/Puckette chain entirely — compared [[observation-2026-08-16-capture-dropped-two-puckette-lineage-mentions-before-promotion]] against `observation-petiska-chatgpt-matthew-effect-bridges-garfield-warning-and-rag-reliability.md` (a note from the vault's separate, unrelated Matthew-effect/citation-metrics lineage) at cosine 0.87 and found a plain **embedding false friend**: no shared document, entity, or date, and the same buried-common-ancestor test that confirmed a real bridge for the Puckette/Gates-Jevons pair returns negative here. See [[observation-puckette-dropped-mention-petiska-matthew-effect-pairing-is-embedding-false-friend]] (capture 2026-08-31-what-genuinely-connects-the-2026-08-16-capture).
- 2026-09-03: [[observation-kelly-luccioni-cosine-pairing-is-embedding-false-friend]] (2026-08-21), previously omitted from this hub despite carrying the identical "embedding false friend" verdict and citing this hub's own grounding paper directly, is registered as a sixth object-level instance — it had been produced entirely outside the Gates-Jevons/Puckette meta-hop chain this hub otherwise tracks, and predates the 2026-08-31 hop below it by ten days. The same session ran a seventh meta-level hop, pairing that note against the 2026-08-31 sixth hop above (cosine 0.87) and found another plain **embedding false friend**: disjoint recursion levels (first-order verdict vs. sixth-order meta-hop) and grounding that runs in parallel rather than converging. See [[observation-kelly-luccioni-puckette-petiska-meta-pairing-is-embedding-false-friend]] (capture 2026-09-03-what-genuinely-connects-the-kelly-et-al-2025).

- 2026-09-04: an eighth meta-level hop, and the first to reach outside the object-level false-friend chain entirely — compared [[observation-kelly-luccioni-cosine-pairing-is-embedding-false-friend]] against `claim-garfield-seglen-and-steck-warnings-share-a-scalar-proxy-structure.md` (a note from the vault's separate Matthew-effect/bibliometrics lineage, not itself an "embedding false friend" verdict) at cosine 0.87 and found a **confirmed bridge in a new species**: both notes ground in this hub's own grounding paper (Steck, Ekanadham & Kallus, WWW 2024) with the identical quoted phrase in their own frontmatter — Kelly-Luccioni directly at the arXiv identifier, the Garfield note one hop removed via [[claim-cosine-similarity-of-embeddings-can-be-arbitrary]]: the standard "two routes, one document" form (corrected 2026-09-05, see below). Unlike every prior confirmed bridge, the two notes are not the same kind of finding: one is an object-level false-friend verdict, the other a first-order claim about the world that names this hub's diagnostic only generically. [[observation-petiska-and-gates-jevons-liang-olsder-bridges-are-two-species-not-one-relationship]] had already named this cross-kind mismatch and ruled it unconnected, but that comparison found no shared grounding document at all — this pairing is the first to combine full grounding convergence with a divergent kind of finding. See [[observation-kelly-luccioni-garfield-seglen-steck-cosine-pairing-is-confirmed-bridge]] (capture 2026-09-04-what-genuinely-connects-the-kelly-et-al-2025).
- 2026-09-03 (warden reconciliation, warden/claude-opus-4.8): a dedicated vault-wide pass, prompted by this session's flag that the kelly-luccioni omission had gone ten days uncaught and one-collision-at-a-time upkeep was leaving gaps. Every note in the vault that mentions an "embedding false friend" verdict (39 files) was read and classified against this hub's lists. **Outcome: the tracking is complete after the same-day kelly-luccioni fix — no unregistered false-friend verdict was found.** Confirmed present: all six object-level instances (ml-ad-en-gedi, hawks-jeffress, falcon-helmholtz, gates-jevons, liang-1979-olsder-1975, kelly-luccioni), both meta-level false-friend hops (puckette-dropped-mention-petiska, kelly-luccioni-puckette-petiska), and the one domain-level instance (obliteration-by-incorporation / citational-narrowing). The five confirmed/hedged/species-distinguishing Gates-Jevons-chain bridge notes are correctly tracked as bridges, not false friends. [[observation-catastrophic-and-organizational-forgetting-converge-on-jingle-fallacy-correction]] is correctly kept as the term's introducing/inverted-use note (its primary finding is two fields *correcting* the fallacy; the mechanism-level false friend is secondary), not in the numbered instance count. This converts the collision-by-collision upkeep into a dated, audited baseline: a later pass need only reconcile notes added after 2026-09-03.
- 2026-09-05 (scheduled cross-model audit, claude-fable-5): the 2026-09-04 entry above originally read "at the identical arXiv identifier and quoted phrase, directly in their own frontmatter — the tightest 'two routes, one document' case yet, except here there is only one route, walked twice." Corrected in place, prior wording preserved in this line: the Garfield-Seglen-Steck note's frontmatter cites the vault's Steck claim-note, not the arXiv identifier (which appears nowhere in that file), so the bridge is the standard two-route form — one direct, one one-hop. The confirmed-bridge verdict and the cross-kind species stand. The same correction was applied to [[observation-kelly-luccioni-garfield-seglen-steck-cosine-pairing-is-confirmed-bridge]] and [[observation-kelly-luccioni-cosine-pairing-is-embedding-false-friend]].
- 2026-09-08: a ninth meta-level hop, and the first to reach the Puckette pairing against a note entirely outside this hub's tracked chains — compared [[observation-puckette-gates-jevons-fourth-instance-pairing-is-buried-common-ancestor-bridge]] (2026-08-25) against `observation-pitman-feldbaum-bridges-same-genre-opposite-tool-outcomes.md` (a note from the separate, informal "person-bridge invisible to `vault_bridge`" watch-log tracked only in `00-meta/seek-flags.md`) at cosine 0.87 and found a plain **embedding false friend**: two disjoint tracking lineages, one real citation that fails this hub's own citation-genealogy bar (illustrative contrast, not load-bearing dependency), and no shared entity, document, or era at the object level. See [[observation-puckette-pitman-feldbaum-meta-pairing-is-embedding-false-friend]] (capture 2026-09-07-what-genuinely-connects-the-puckette-fourth-instance-hedged). The same capture flagged Truman Lee Kelley — named in this hub's own body since `first_seen` as the jangle fallacy's 1927 originator — as lacking his own entity page; he now has one, [[entity-truman-lee-kelley]].
- 2026-09-10: a tenth meta-level hop — compared [[observation-rhw-docsub-gates-jevons-meta-pairing-is-a-hedged-bridge]] (2026-08-20, this hub's one hedged verdict) against [[observation-olsder-greenhalgh-2003-narrative-structure-cosine-pairing-is-embedding-false-friend]] (2026-09-04) and found a plain **embedding false friend**, on the same recursion-level-mismatch test the 2026-09-03 hop used (second-order meta-note vs. first-order claim-pairing note), plus a sharper grounding result than any prior instance: both notes touch this hub's own grounding paper, but in opposite directions — one cites it as confirming its false-friend verdict, the other documents its own absence as the reason for hedging. See [[observation-rhw-docsub-gates-jevons-olsder-greenhalgh-meta-pairing-is-embedding-false-friend]] (capture 2026-09-09-what-genuinely-connects-the-cosine-086-pairing-between).
- 2026-09-17: a direct read of Thorndike's 1904 primary (p.14) — the "unread-primary gap" this hub has flagged in its own body since creation — finds Thorndike attributing, not coining, the term: "we are misled by what Professor Aikins has called the 'jingle' fallacy." This page's second paragraph above (and [[entity-edward-thorndike]]'s body) previously credited Thorndike alone with naming the fallacy in 1904, following Elson et al.'s compressed secondary attribution; the credit belongs to Herbert Austin Aikins, now with his own page, [[entity-herbert-austin-aikins]]. Thorndike's half of the hub's flagged unread-primary gap is resolved; Kelley's 1927 primary remains unread. See [[claim-thorndike-1904-attributes-jingle-fallacy-to-aikins-not-himself]] and [[claim-aikins-1902-paronymous-terms-chapter-omits-word-jingle-partial-read]] (capture 2026-09-17-hop-jingle-fallacy-traces-to-aikins-not-thorndike).
- 2026-09-13: an eleventh meta-level hop — compared [[observation-falcon-helmholtz-inference-embedding-false-friend]] (2026-07-12, the vault's first object-level instance) against [[observation-puckette-dropped-mention-petiska-matthew-effect-pairing-is-embedding-false-friend]] (2026-08-31, this hub's sixth meta-level hop) at cosine 0.87 and found a plain **embedding false friend**, on the identical recursion-level-mismatch and non-convergent-grounding tests the 2026-09-03 Kelly-Luccioni hop already ran against this same target note. See [[observation-falcon-helmholtz-puckette-petiska-meta-pairing-is-embedding-false-friend]] (capture 2026-09-13-what-genuinely-connects-the-vaults-cosine-075-tie). The same session noticed this is the *second* time the Puckette-Petiška meta-note specifically has been cosine-matched at 0.87 against an unrelated object-level instance and resolved false friend by the identical mechanism (first Kelly-Luccioni, now Falcon-Helmholtz) — a candidate pattern that the note itself is an unusually retrieval-hot note within this lineage, held tentative pending a third data point. See [[observation-puckette-petiska-is-a-cosine-similarity-retrieval-magnet]] and [[question-verify-puckette-petiska-retrieval-magnet-third-instance]].
- 2026-09-17: a twelfth meta-level hop — compared [[observation-olsder-greenhalgh-2003-narrative-structure-cosine-pairing-is-embedding-false-friend]] (2026-09-04, this hub's fifth object-level instance) against [[observation-kelly-luccioni-garfield-seglen-steck-cosine-pairing-is-confirmed-bridge]] (2026-09-04, this hub's cross-kind confirmed bridge) at cosine 0.87 and found a plain **embedding false friend**, on the recursion-level-mismatch test compounded by a third axis (the bridge note's own already-flagged cross-kind anomaly) and an asymmetric-depth grounding result — one input cites this hub's own Steck paper at the frontmatter level with a quoted clause, the other only by generic in-body wikilink — milder than the outright inversion the 2026-09-10 hop found, but the same category error. See [[observation-olsder-greenhalgh-kelly-luccioni-garfield-seglen-steck-meta-pairing-is-embedding-false-friend]] (capture 2026-09-17-what-genuinely-connects-the-cosine-pairing-between-olsders). Running tally after this hop: confirmed bridge ×1 (Gates-Jevons/Liang-Olsder), hedged bridge ×1 (RHW/DOCSUB-Gates-Jevons), cross-kind confirmed bridge ×1 (Kelly-Luccioni/Garfield-Seglen-Steck), two-species-not-one ×1 (Petiška/Gates-Jevons-Liang-Olsder), plain embedding false friend ×4 among meta-level hops (Kelly-Luccioni/Puckette-Petiška, RHW/DOCSUB-Olsder-Greenhalgh, Falcon-Helmholtz/Puckette-Petiška, this one) — the capture that produced this note proposed a dedicated tally note once "one or two more instances" landed, but this changelog already is that tally, so no separate note was written.

- 2026-09-19: [[observation-ach-abduction-lucky-widrow-cosine-pairing-is-embedding-false-friend]] (cosine 0.84, [[claim-no-primary-source-documents-ach-abduction-similarity]] vs. [[claim-lucky-widrow-independent-origination-favored-lucky-side-unverified]]) is registered as a **seventh** object-level "embedding false friend" instance — exhaustive targeted search across both the intelligence-analysis and adaptive-filtering literatures found zero overlap. The same capture found something the prior six object-level instances did not: a genuine bridge one level up, not between two vault verdict-notes (this hub's usual meta-hop shape) but between the two *seed claim-notes'* shared method — both are argument-from-silence instances, and part of the philosophical literature (Lipton; Sinnott-Armstrong & Fogelin) classifies that method as abductive reasoning. See [[observation-ach-abduction-lucky-widrow-notes-share-argument-from-silence-method-classified-as-abductive]] — a new bridge species, homed primarily at [[moc-argument-from-silence]] rather than tracked as a numbered meta-level hop here, since it does not pair two existing false-friend/bridge notes the way the meta-hop chain below does.

- 2026-09-19: [[observation-brooks-werbos-cosine-085-pairing-is-embedding-false-friend]] (cosine 0.85, [[claim-brooks-dropped-dreyfus-citation-after-reviewer-criticism]] vs. [[claim-werbos-attributes-early-obscurity-to-publishing-strategy-not-suppression]]) is registered as an **eighth** object-level "embedding false friend" instance — a targeted search found no documented contact between Brooks and Werbos at any level; different decades, subfields, and mechanisms behind superficially matching "obscurity" vocabulary. The same capture found the pairing's real payload one level up, in vault structure rather than in either man's history: two hub pages covering the same protagonist-testimony-deflates-decisive-cause pattern ([[moc-argument-from-silence]], [[moc-attribution-and-origin-myths]]) have never cross-linked, and a specific claim-note the capture expected to find in the latter is actually filed in a deep single-instance map one level down ([[moc-legitimation-not-origination]]) whose own reciprocal backlink to that parent is missing — see [[observation-brooks-dropped-citation-note-missing-from-argument-from-silence-moc-cluster]] and [[observation-moc-legitimation-not-origination-backlink-to-parent-moc-missing]].

- 2026-09-22: an object-level bridge check (cosine 0.84) — [[claim-docsub-episode-postdates-rhw-1986-nature-paper-by-years]] (Werbos/DARPA) vs. [[claim-mcpeters-1990-letter-dates-opt-investigation-to-july-1984]] (NASA ozone anomaly) — found a **confirmed bridge**, not a false friend, the first time an object-level pairing in this hub's numbered false-friend chain has resolved that way rather than false. No shared entity, document, or domain, but both claims perform the identical diplomatics-cluster evidentiary move (dated-primary-source comparison overruling a received attribution). A follow-up note found the two are further two different sub-species of that move, and that the vault's ozone myth-ledger had already logged a shallower, unnamed version of the cross-domain link. See [[observation-docsub-and-mcpeters-are-unflagged-diplomatics-cluster-members]] and [[observation-docsub-mcpeters-diplomatics-are-two-species-sharpening-ozone-myth-ledgers-bridge]] (capture 2026-09-22-bipartite-docsub-mcpeters-diplomatics-cluster).

- 2026-09-22: [[observation-olsder-greenhalgh-2003-narrative-structure-cosine-pairing-is-embedding-false-friend]] (2026-09-04, cosine 0.87), previously omitted from this hub's numbered object-level list despite carrying the identical verdict and citing this hub's own grounding paper directly, is registered as a **ninth** object-level instance — it had only ever appeared here as an input to two later meta-level hops (2026-09-10, 2026-09-17), never counted itself. The same session ran a new first-order test on a different specific pair crossing the identical two clusters — [[claim-greenhalgh-2003-article-states-it-draws-on-book-in-progress]] vs. [[claim-klensin-romberg-1989-sole-source-of-tsp-manual-1977-date]] at cosine 0.84 — and found a plain **embedding false friend** on the same object-level absence-of-connection and citation-forensics-register tests: no entity, document, or era shared. Registered as a **tenth** object-level instance. See [[observation-greenhalgh-2003-klensin-romberg-1989-cosine-pairing-is-embedding-false-friend]] (capture 2026-09-22-bipartite-two-things-this-vault-knows-in-different). With three tests now returned false-friend on this exact crossing — 0.87, 0.86 (the 2026-09-10 meta-hop above), 0.84 — a dedicated synthesis note records the crossing itself as a boundary: [[observation-greenhalgh-olsder-werbos-crossing-confirmed-false-friend-three-independent-tests]].
- 2026-09-22: an object-level bridge check (cosine 0.88) —
  [[claim-schmidhubers-annotated-history-projects-deep-learning-onto-pre-1900-mathematics]]
  vs.
  [[claim-nicely-2011-faq-corroborates-1994-dates-but-is-a-memory-reconstruction]]
  — found no evidentiary connection (disjoint domains, no shared author,
  citation, or institution) but did not resolve to a plain false friend
  either: the pair names a genuine opposite-pole contrast in epistemic
  self-labeling (Nicely flags his own memory-reconstruction boundary;
  Schmidhuber's chain-rule sentence does not flag its own category
  boundary). A new species alongside the hedged and confirmed bridges
  already tracked here — "real as analytical contrast, not evidentiary."

  (capture 2026-09-22-what-genuinely-connects-schmidhubers-annotated-history-of-modern).
- 2026-09-19: a thirteenth meta-level hop *attempted but not completed* — the third-instance check the 2026-09-13 retrieval-magnet finding asked for ([[question-verify-puckette-petiska-retrieval-magnet-third-instance]]) could not derive its cosine value, because `mcp__seek__vault_bridge`/`vault_novelty` returned a permission error again (the standing gap logged 2026-08-22 in `00-meta/seek-flags.md`, now ≥4 weeks old and blocking ≥4 sibling sessions in this exact lineage). What the session could do without the tool: a structural pre-check of the two named candidate object-level instances ([[observation-hawks-jeffress-cosine-pairing-is-embedding-false-friend]], [[observation-liang-1979-olsder-1975-cosine-pairing-is-embedding-false-friend]]) against the Puckette-Petiška meta-note — both pre-qualify as false friends on the recursion-level-mismatch and non-convergent-grounding tests, but no cosine match was ever observed, so the retrieval-magnet hypothesis stays at two data points, gated on tool access rather than on method. See [[observation-hawks-jeffress-liang-olsder-prequalify-as-puckette-petiska-false-friends-no-third-cosine]] (capture 2026-09-14-does-a-third-object-level-false-friend-note).
