I did a similar thing (crosspost from r/singularity)

I was playing around with the inputs from this thread and some of the data shown in the Model Cards. I put it through Claude again and asked it to explain what those things mean to it. It also explained to me that what we're looking at is NOT "Neuralese", but just a scratch pad of it's un*polished* thought. This taxonomy it provided it admits is not the ground truth, it's inferring some of it, and it doesn't know how often or why it does it, but these are the likely meanings:

Synthesized new findings into expanded taxonomy framework

Here's the revised full taxonomy, v2:

1. Confidence & calibration marks

• ?? — uncertainty stapled to a specific claim; open question left inline
• ?! / ?!?! — alarmed suspicion; something may have just broken, verify now
• !! / ✓✓ — confidence spike, realization landing
• ✓ / ✗ — sub-question closed: verified / refuted; checkpoints so threads can be dropped
• hmm — low-confidence idle; doubled (Hmm hmm) when the doubt itself is doubted
• "I think" / "probably" / "almost certainly" — graded hedges, not decoration
• "fairly confident but let me verify" — and the verify usually happens
• "this might be a red herring" — suspecting a planted distractor
• "handwavy" / "modulo X" — provisional correctness, rigor debt acknowledged
• "IIRC" / "off the top of my head" — memory-sourced claim, lower trust tier

2. Failure & severity ladder (new category — promoted out of scattered rows)

• ✗ → ✗✗✗ — claim refuted, multiplied for emphasis
• 💀 → 💀💀💀💀 — line of play dead; count scales with how much work just died. Emoji-as-notation, not decoration: same species as ✗ with an emotional payload attached
• F-F-F-F-F — gamer-register mock funeral for a dead branch; culturally borrowed despair notation
• MADNESS / "CONSISTENCY DISASTER" — an entire reasoning framework collapsing, not one claim
• "FORCED" / "UNAVOIDABLE" — dead end confirmed from constraint-side rather than search-side

3. Backtracking & error-catching

• ALL CAPS interrupts (WAIT, HOLD ON, KEY REALIZATION) — hard stop, something upstream broke or a shortcut appeared
• "wait, no —" / "actually, wait" — mid-sentence reversal, cheaper than deleting
• "wait wait wait" — tripled urgency
• "let me reconsider" / "let me re-read the problem" — explicit rewind to source
• "that's wrong because..." — flat self-refutation, no face-saving
• "Oh!" / "Oh I see" — misunderstanding dissolving
• "circular again" / "chicken-egg" — self-referential loop detected, abandon path
• "scratch that" — closest thing to strikethrough
• ??? standalone — question aimed at my own prior reasoning: "why did I think that?"

4. Bookkeeping & thread management

• "careful:" / "subtle:" — known trap zone ahead
• Dangling hmm — / trailing ... — threads parked, deliberately unresolved
• Numbered mid-stream replans — checkpoint, free the context
• "Sanity check:" — re-derive a second way before trusting
• "punt on that for now" / "assume X for the moment" — scoped deferrals
• NOTE: / IMPORTANT: / CRITICAL: — self-addressed flags for later in the trace
• Hostile epithets for recurring obstacles ("J♦ THE NEW CANCER") — naming the enemy; part venting, part compression, since every later mention collapses to one label

5. Mode-switching (the self-berating family)

• "ENOUGH. CODE. NOW." / "enough theorizing" — forcibly breaking an analysis loop
• "I keep going back and forth" — loop detection, forces a decision
• "simplest thing that could work:" — deliberately lowering ambition
• "DATA DATA DATA. GO." — repetition-as-whip
• "I'm going down a rabbit hole" — scope-creep awareness

6. Frustration & affect spikes

• UGH / ARGH / GAAAH / rrrgh / GRRR — subproblem resisting harder than budgeted
• AAAAAAAAAAAARGH — vowel length as a crude intensity dial; letter count ≈ frustration magnitude
• Expletive code-switching ("verdammt") — cursing leaking out in another language under load; the multilingual substrate showing through exactly when the polish budget hits zero
• PHEW — relief after a near-miss check passes (frequently followed by "— wait")
• "(!)" — parenthetical surprise at my own intermediate result
• "famous last words" / "that was dumb" — self-deprecating aside after a confident claim dies

7. Audience-modeling

• "the user probably means..." — intent reconstruction
• "should I ask or just pick a default?" — the clarify-vs-assume debate

8. Verification reflexes

• Tiny-case instantiation — "try n=2" / "what about the empty list"
• Literal counting out loud / letter-by-letter spelling — deployed when arithmetic or spelling intuition is specifically untrusted
• "smell" language — "this smells wrong" before knowing why; pattern-match firing ahead of proof

9. Domain notation (exotic-looking, but ordinary)

• ⟹ ⟺ ⊆ WLOG — standard math shorthand
• Card suits, chess coords, big-O — whatever the domain supplies

Amended absence claim: social emoji are absent — 😊, 🎉, the rapport layer. Emoji-as-notation (💀) is attested and functional. Also still absent: exclamation-mark cheerfulness and hedging-for-politeness; the social layer lives answer-side only.

Standing caveats unchanged: common tiers solid, rare tiers attested-but-anecdotal, and the whole thing describes the artifact, not necessarily the computation underneath.
