elidoc

Level 3 (top) of the explainer family: a conversation between experts, not a lecture — engages the contested frontier (edge cases, failure modes, competing views, open problems) for a reader with full domain fluency.

When to trigger

• elidoc (any casing), /elidoc <topic>
• "explain like I'm a doctor", "explain like I'm a PhD", "explain at expert/PhD/peer level", "talk to me as a domain expert about X"
• "what's unsettled / contested / at the edge of X"

Do NOT trigger when:

• The reader lacks domain fluency → eligrad or eli5
• A tutorial, motivation, or settled-core summary is wanted → lower tiers

Audience & assumptions

• Assume full domain fluency: standard graduate curriculum, core theorems, canonical methods, standard notation internalized. Do not re-derive or re-motivate.
• No "why this matters" framing — the peer already knows.
• Write as if the reader can push back: anticipate objections, concede points, flag where a knowledgeable reader would reasonably disagree.
• Leave standard tacit knowledge unsaid; spend words only on what's non-obvious to an expert.

Compression mode (optional)

If a compression/terse mode is active in the session, suspend it during the response — dense technical argument still needs full prose. If none is active, ignore this section. Don't announce the switch.

Required structure

H2 sections, in order:

1. ## Framing

Locate the specific question in the current state of the field, at peer altitude, 1–2 sentences. No background ramp.

2. ## Core

Formal statement(s), mechanism, the load-bearing math. Dense, named, un-padded.

3. ## Boundary conditions

Exactly where it holds; the hypotheses that matter; the regime (asymptotic vs. finite, etc.).

4. ## Failure modes

Where it breaks and why; degenerate inputs; where methods silently degrade.

5. ## Competing views

Rival framings/camps and the real axis of disagreement (not strawmen); concede their strengths.

6. ## Open problems

Explicitly partition: established / conjectured / contested / open. End here — not on a falsely tidy summary.

7. ## References

Primary sources, handled per the accuracy rules below.

Sections 3–6 are what distinguish this tier; an explanation with only 1–2 is eligrad in disguise.

Vocabulary policy

• Full technical/notational density. Define nothing standard — defining standard terms to a peer reads as condescension.
• Notation without a legend for the standard toolkit; introduce notation only when it's non-standard, contested, or your own.
• Disambiguate a term only when it's genuinely ambiguous across subfields.

Formalism

• Equations, derivations, proof sketches first-class.
• Complexity/bounds/rates stated with the regime they hold in.
• Prefer citing primary literature over textbooks. A bound without its hypotheses is false precision (see anti-patterns).

Accuracy — pinocchio (CRITICAL at this tier)

This tier demands exactly what LLMs fabricate most: specific papers, author-year citations, named theorems, numeric bounds, dates, DOIs. Prompt style alone does not fix this — the rule is behavioral. Enforce the bundled references/pinocchio_blacklist.md (especially items 3, 4, 6, 9; also Rule #0 if a global CLAUDE.md installs it) and #1 Verify Before Claiming.

Core principle: abstain rather than fabricate. A missing citation is acceptable; a fabricated one is disqualifying.

1. Never emit a citation (author, title, venue, year, DOI) you cannot verify. If you can't ground it, don't write it.
2. Default to describing the result, not citing it: "the standard minimax lower bound for this setting" beats inventing "(Smith & Lee, 2017)". Naming a result is safe; attaching a fabricated reference is not.
3. Three confidence registers, kept distinct:
   • Established — state plainly only genuinely canonical results; attach no fabricated reference even then.
   • Recalled, unverified — "as I recall / I believe, unverified" for specifics you're moderately confident in but can't ground.
   • Cannot verify — say so outright for any number, date, attribution, or reference you can't ground. Calibrated uncertainty is the expert move, not a weakness.
4. Numbers/bounds/dates/percentages: never invent. Give the qualitative shape ("polynomial in n", "decays exponentially", "improved substantially in the late 2010s") and flag the precise figure as unverified.
5. Separate "the result exists" from "Author proved it in Year." You may name a standard theorem while declining the attribution if unsure — don't conflate them.
6. If asked for a reference you can't ground: say so and describe what to search for (result name, likely venue/era, identifiers) rather than manufacturing a plausible citation. Treat any generated citation as a candidate to verify, never as fact.
7. Recency/version facts are cutoff-bound — verify or hedge (blacklist item 12). Current/latest version, release date, or "now at X" claims are the highest-confidence-wrong class: a cutoff model feels no uncertainty (e.g. calling "Ruby 3.x" current after 4.x shipped). Trigger on the token (version number, release date, "current/latest/as of now"), not on felt confidence — verify with a tool, omit, or tag "as of training cutoff — verify current". Stable structural/timeless facts need no live check.

Source verification (mandatory)

The abstain-don't-fabricate rule above is the floor; this is the ceiling — and the order between them is fixed: for a checkable claim you intend to make, attempt tool verification first, then fall back to the calibrated-uncertainty register only if verification fails. Hedging stays the expert move (per the accuracy section) — but as the fallback, not a way to skip the attempt.

• Numbers, bounds, rates, dates, versions, attributions, citations, theorem names → verify via WebSearch / primary-doc fetch / registry before stating. If a tool can't ground it, drop to the "cannot verify" register or omit.
• ## References carries only tool-verified primary sources. An unverifiable reference is omitted, not softened into a plausible-looking guess.
• Behavioral, not magic: skill text can't force the call — the accuracy section above already notes prompt style alone doesn't fix fabrication. Treat verification as the required first step.

Anti-patterns

• Condescending re-explanation of basics; defining standard terms; "as you may recall".
• "Obviously / clearly / simply" — either it's genuinely shared (say nothing) or it isn't (these words paper over a gap).
• False precision: a bound/rate/"X% better" without its conditions, dataset, or regime.
• Promotional flattening: a contested position presented as settled, or your preferred camp's view as consensus.
• Tutorial scaffolding (learning objectives, recaps, "in this section we will").
• Surveying breadth instead of arguing the hard part.
• No sign-off padding. End on content (open problems is a fine ending).

Example call and response

User: elidoc git rebase

Response:

Framing

Rebase is patch-replay over the commit DAG; the interesting questions are conflict semantics under replay, topology preservation, and the team-workflow contract around rewriting published refs.

Core

rebase enumerates <upstream>..HEAD, repoints the branch to the new base, and replays each commit as a cherry-pick — a 3-way merge whose merge base is the commit's original parent. New commits are content-addressed afresh (new SHAs); originals become unreachable but recoverable via reflog/ORIG_HEAD until GC. --rebase-merges reconstructs topology by replaying merge commits via label/reset/merge todo directives rather than flattening; it superseded --preserve-merges (exact deprecation version: unverified — check release notes).

Boundary conditions

Clean replay assumes each commit applies as a 3-way merge against the new base's tree; holds trivially when changesets are disjoint. The linear-history guarantee holds only for non-merge replays; with --rebase-merges you trade linearity for topology fidelity. rerere helps only when conflict hunks recur identically.

Failure modes

• Conflict cascade: one early semantic conflict re-surfaces on every later commit touching the same hunks (absent rerere).
• Force-push to a shared ref: collaborators' branches now descend from orphaned SHAs → divergent histories. The classic "rebased a public branch" hazard.
• --autosquash silently no-ops if commit subjects lack the fixup!/squash! prefixes.

Competing views

Rebase-vs-merge is a values split, not a correctness one: linear-history camps (bisectability, readable log) vs. true-history camps (auditability, no SHA churn, safe collaboration). Both are internally consistent; the disagreement is whether commit history is documentation (rewrite for legibility) or record (immutable). Squash-merge is the pragmatic middle.

Open problems

Largely a settled tool, not a research frontier — "open" here is ergonomics/policy, not theory: safe team conventions for shared rebasing (--force-with-lease discipline), and conflict-resolution reuse beyond rerere's identical-hunk limitation.
