The search-UI `status` filter wiring +in `search-filters.js` was deliberately partial in this phase *(completed +2026-06-10 — see the Phase 5 Met note)*. + +**All five phases done.** Refinements next; see the Phase 5 Met note for the +documented deferrals (search-UI status filter, bibliography annotation from +Phase 3, and pull-from-Wayback at fetch time — all three implemented +2026-06-10). + +**Refinements (2026-05-22).** A code-review pass found and fixed several +correctness and posture issues across the system: + +- **Missing committed artifact no longer re-fetches silently.** `cmd_fetch` + used to skip its SHA guard when the artifact was absent and then download + fresh bytes whose hash differed from the recorded `sha256` — replacing the + recorded snapshot without surfacing it. The guard now also halts when + `PROVENANCE.json` is present but the artifact is missing, requiring the + author to restore the committed bytes before rebuilding. +- **`archive/removed.yaml` is now enforced in `fetch` and `check`.** It was + only read by `gc`. A removed URL re-added to the manifest now halts + `cmd_fetch` loudly; `cmd_check` skips removed URLs so the link-rot + scanner does not keep probing a deliberate takedown. +- **SHA verification closed the `.venv`-bypass hole.** The original + decision relied solely on `archive.py fetch` re-hashing, but that step is + `.venv`-gated — a contributor or deploy host without `.venv`, or a direct + `cabal run site -- build`, would publish a tampered artifact unchecked. + `build/Archive.hs` now also re-hashes via `sha256sum` from + `loadArchiveEntries` and halts the build on a mismatch, so the guarantee + holds independent of the Python step. +- **Raw artifacts are no longer publicly indexable.** Pass 1 added a + `robots.txt` `Disallow: /archive/`, which pass 2 then reverted (see + below — it was counter-productive). Pass 1's other change — injecting + `` into every new HTML + snapshot alongside the archive CSP — remains in place; the + deploy-side header for raw PDFs landed in pass 2 as `nginx/archive.conf`. +- **The documented `archive.py refresh {slug}` subcommand is implemented.** + It clears the slug's directory, re-fetches via `cmd_fetch`, and records + the prior `sha256` as `previous-sha256` in the new `PROVENANCE.json`. The + URL-changed error message in `cmd_fetch` now points at it instead of + asking the author to delete the directory by hand. +- **`url_aliases` widened** to the design's full equivalent-URL set: + tracking-parameter stripping (`utm_*`, `fbclid`, `gclid`, `mc_*`, `ref`, + `igshid`, `_hsenc`, `_hsmi`, `mkt_tok`) and arXiv abs / pdf / versioned / + `.pdf` form expansion. Phase 1 had deliberately kept these as a Phase 4 + deferral, but Phase 4 missed the follow-through. +- **`X-Robots-Tag: noarchive` is now honoured on both HEAD and GET.** Some + servers omit the header on HEAD but emit it on GET; HTML capture now + aborts if either response carries the directive. + +Three smaller items remain documented and deferred: + +- **Archive tags joining the site-wide tag indexes.** `manifest.yaml`'s + `tags:` is authored but `Tags.hs`/`Patterns.tagIndexable` does not yet + ingest archive entries — it needs a Tags.hs-side integration with its + own design pass (archive pages aren't `match`ed Hakyll items in the + normal way). +- **`archive.py suggest`** (bibliography discovery — diff `.bib` URLs + against the manifest) is documented but not implemented. *(Implemented + 2026-06-10 — see the status note below.)* +- **The controlled-host end-to-end link-rot test** (reserve + `archive-test.levineuwirth.org`, run it through a 14-day-spanning fail + streak, watch the flip happen) is inherently a multi-week real-world + verification the author runs; the hysteresis logic is unit-tested + deterministically and the rendering side is verified by a hand-crafted + `rotted` state file. + +**Refinements pass 2 (2026-05-23).** A second code-review pass surfaced +correctness gaps the first pass missed: + +- **`refresh` is now atomic.** It used to delete the slug directory and + then call `cmd_fetch`; a failed re-fetch left the entry with no + snapshot at all, while `refresh` returned 0 (because `cmd_fetch` + reports per-entry skips, not a process failure). The slug directory is + now *renamed* to a `.refresh-backup` sibling; success removes the + backup, any failure restores it. Verified by hiding the `monolith` + binary and confirming the prior snapshot survives intact. +- **Invalid `visibility` values fail closed.** The `ManifestEntry` parser + used to accept any string and only treat the exact `"private"` as + private — a typo like `privte` would publish a work the author intended + to keep offline. The parser now rejects any value other than `public` + or `private`, and `readManifest` halts the build on any parse error of + a present file (instead of warning + returning an empty list — that + silent-skip was for `file absent`, not `file present but corrupt`). +- **Lookup-side URL normalisation.** Alias generation alone cannot cover + unbounded forms (arXiv versions, arbitrary tracking-parameter + combinations). `ArchiveIndex` now normalises both index keys and + lookup inputs through the same `normalizeUrl` (drop fragment, strip + tracking, fold http→https, arXiv-canonicalise, trim trailing slash). + Verified: `https://cr.yp.to/aes-speed.html`, + `https://cr.yp.to/aes-speed.html?utm_source=mail`, and + `http://cr.yp.to/aes-speed.html/` all match the same archived entry. +- **Raw-artifact indexing posture corrected.** The Phase-5 `robots.txt` + `Disallow: /archive/` was counter-productive: a URL blocked by + robots.txt can still appear in results when externally linked, and the + Disallow also prevents compliant crawlers from reading the wrapper + pages' ``. The Disallow is reverted; a new + `nginx/archive.conf` snippet emits `X-Robots-Tag: noindex, noarchive` + for the whole `/archive/` tree, which crawlers honour for any resource + (HTML and PDF alike). The deploy vhost should `include + snippets/archive.conf`. +- **`cmd_wayback` skips `removed.yaml`.** The eviction procedure says + record in `removed.yaml` *before* dropping the manifest line; `fetch` + and `check` now honour that ordering, but `wayback` did not. A removed + entry whose manifest line was still in place could be submitted to a + third-party archive after a takedown was recorded. +- **The shipped HTML snapshot was refreshed in the working tree** so it + carries the noarchive meta the Phase-5 inject promises. `archive.py + refresh djb-aes-speed` re-fetched cr.yp.to, applied + `inject_archive_metas`, and recorded the prior SHA as `previous-sha256`. + `archive/djb-aes-speed/{snapshot.html, PROVENANCE.json}` now reflect the + new bytes; matching SHA is verified by `Archive.hs`. *Caveat surfaced + in pass 3 (below): the prior snapshot was not committed at the moment + of this refresh, so its bytes are no longer recoverable via `git log + -S`. A pass-3 fix to `refresh` now refuses to replace an uncommitted + prior, but the historical artifact survives — `previous-sha256` + records a hash whose bytes this working tree cannot reproduce.* +- **The URL-changed error in `cmd_fetch`** now points at + `archive.py refresh {slug}` instead of asking the author to delete the + directory by hand. + +Tag integration remains the one deferred refinement (it needs a Tags.hs +design pass). + +**Refinements pass 3 (2026-05-23).** A third audit surfaced gaps the pass-2 +fixes didn't fully close: + +- **`refresh` refuses to replace an uncommitted prior snapshot.** Pass 2 + preserved a prior snapshot through *failed* re-fetches, but a *successful* + one happily discarded uncommitted bytes — `previous-sha256` then pointed + at a hash no `git log -S` could recover. Pass 3 shells out to `git + ls-files` + `git diff --quiet HEAD` and refuses the refresh unless both + the prior PROVENANCE.json and its artifact are tracked and clean. +- **`refresh` is atomic across *every* exit path.** Pass 2 handled the + ordinary `cmd_fetch returns 0 but the artifact wasn't produced` case but + not fatal `sys.exit`s (e.g. a `removed.yaml` conflict halting `cmd_fetch` + mid-refresh) nor mid-refresh exceptions, and it never rolled back the + `data/archive-index.json` rewrite. The work is now wrapped in + `try/finally` that restores both the slug directory and the index on any + exit path — normal failure, `SystemExit`, `KeyboardInterrupt`, or + exception. +- **Removal enforcement now uses the same equivalence as link matching.** + Pass 2 introduced `normalizeUrl` for incoming citations but compared + removals as literal URL strings, so a tracking-laden manifest URL could + bypass a takedown. Python gains `normalize_url` mirroring the Haskell + helper, and `fetch` / `check` / `wayback` compare normalised forms. + `cmd_fetch` additionally rejects two manifest entries whose canonical + forms collide — that would otherwise route both under one slug. +- **`fetch_html` honours `X-Robots-Tag: noarchive` on the captured GET too.** + Pass 1 added HEAD + ranged-GET probes, but a server can emit the header + only on the full document response. The Python tool now downloads that + response itself, checks its header and body directives, then passes those + exact bytes to `monolith --base-url ... -` so the saved snapshot is not + obtained through a second unobservable document request. +- **`nginx/archive.conf` is wired into the deploy template** and + re-`include`s `security-headers.conf` inside its `location` block. + `nginx/vhost.conf.example` now includes `archive.conf`; the snippet + itself re-emits the baseline headers because nginx's `add_header` chain + is inherited from a parent only when the current context declares *no* + `add_header` directives — without the re-include, /archive/ would lose + HSTS, CSP, etc. +- **Contract doc cleanups.** The Phase-5 paragraph claiming `robots.txt` + disallows `/archive/` is reworded to acknowledge the pass-2 reversal; + the Phase-1 checkbox claiming `Archive.hs` does not re-hash is updated + to point at `verifyArtifactSha`; the pass-2 note about the refreshed + djb snapshot now carries the caveat that its prior bytes were + uncommitted and are therefore unrecoverable. + +The historical `previous-sha256` value in `archive/djb-aes-speed/ +PROVENANCE.json` is left in place: it is a truthful record that *a* prior +snapshot existed and what its hash was. It just is not recoverable from +git in this working tree — the pass-3 `refresh` precondition exists so +that property is never broken again. + +**Refinements pass 4 (2026-05-23).** A fourth audit completed the +failure-closed paths: + +- **Direct Hakyll builds now enforce removals and missing-artifact failures.** + `Archive.hs` reads `removed.yaml`, rejects normalized manifest conflicts + and duplicate archive targets, and aborts if provenance exists without its + artifact. `ArchiveIndex.hs` filters the generated index through the live + manifest minus normalized removals, so a stale ignored index cannot retain + archive affordances after a takedown when `archive.py` was skipped. +- **`refresh` verifies the prior bytes before replacing them.** A prior + snapshot must now be present, tracked, clean, and match its recorded + SHA-256 before its hash can be written into `previous-sha256`. +- **Failed refresh restores an originally-absent index state.** If + `data/archive-index.json` did not exist before a failed refresh, any index + created by the attempted fetch is deleted during rollback. + +The genuinely-open questions that remain are collected at the end — the list is +short. + +**`archive.py suggest` implemented (2026-06-10).** The bibliography-discovery +subcommand from the design is built: `make archive-suggest` scans `data/*.bib` +for `url` / `doi` fields (per entry the `url` field wins; a DOI-only entry +resolves to `https://doi.org/{doi}`), diffs them against `manifest.yaml` and +`removed.yaml` under the same `normalize_url` equivalence the link-annotation +filter uses, and prints manifest-ready `- url:` lines, each preceded by +`# cited by {bibfile}:{key}` comments (a work cited from several papers prints +once, with every citer). Read-only and offline: it never edits the manifest +and performs no network I/O. Known equivalence gap, surfaced by the first real +run: a work archived under its landing URL but cited via its DOI (e.g. +FIPS 203 — archived as the `nvlpubs.nist.gov` PDF, cited as +`doi.org/10.6028/NIST.FIPS.203`) is re-suggested, because nothing offline can +equate the two forms. That is the same gap that denies those bibliography +links an archive affordance, so the suggestion is honest — the fix, if wanted, +is alias-level (manifest or `url_aliases`), not suppression in `suggest`. + +**Manifest `aliases:` field implemented (2026-06-10).** The alias-level fix +above: an optional authored `aliases:` list per manifest entry for equivalent +URLs that normalisation cannot derive (the DOI ↔ landing-URL case). Aliases +are matching metadata, not identity — editing them rewrites the index on the +next fetch, no `refresh` involved. Enforcement mirrors canonical URLs on both +sides of the build: the `archive.py fetch` pre-scan and `Archive.hs`'s +`validateManifestEntries` each reject an alias that collides with another +entry (directly or via aliases) or that matches a `removed.yaml` takedown, +and `ArchiveIndex.flatIndex` additionally drops alias keys matching recorded +takedowns so a stale index cannot keep annotating a removed work. `suggest` +counts aliases as covered. Applied: `nist-fips-203` now carries +`https://doi.org/10.6028/NIST.FIPS.203`, so the simd paper's DOI citation +resolves to the archived PDF and `suggest` no longer re-suggests it. + +**Link-rot scan scheduled (2026-06-10).** The scan now runs unattended: a +systemd user timer (`systemd/archive-check.{service,timer}`, symlink-installed +on the build machine) fires `make archive-check` daily. Going unattended +exposed a hysteresis hazard hand-run scans masked — a machine left offline +would record a `fail` against every entry, and three such scans spanning two +weeks would flip the whole archive to `rotted` — so `cmd_check` gained a +canary guard: `https://levineuwirth.org/` unreachable → scan inconclusive, +state untouched, exit 0. Details in the Phase 5 section. + +**Fetch-time Wayback fallback implemented (2026-06-10).** The design's +"original already dead at first fetch → pull the most recent existing Wayback +capture" promise is now real. `fetch_pdf`/`fetch_html` classify their +failures (`ok` / `dead` / `skip`), and only a *dead* original — not a +`noarchive` refusal, cap skip, or tooling failure — falls through to +`fetch_from_wayback`, which pulls the raw `id_` capture bytes through the +normal pipeline, honours a preserved `X-Archive-Orig-X-Robots-Tag: +noarchive`, re-detects the artifact type against the capture (the dead +original's Content-Type probe degrades to the html default), and records +`fetched-from` + `wayback` in `PROVENANCE.json`. `refresh` deliberately +excludes the fallback: a dead original fails the refresh and restores the +prior first-hand snapshot. Mechanics in Wayback Machine — non-blocking. + +**Bibliography annotation implemented (2026-06-10).** The Phase 3 follow-up +is done: bibliography entries now carry the same archive affordance (and +rotted-link flip) as body links. The gating CSL-URL check passed — +citeproc renders entry URLs as `Link` inlines — so `Filters.Archive` exports +`annotateBlock` and `Citations.hs` applies it after `enhanceEntry` in both +`renderBibDiv` (essay bibliographies) and `renderBibliographyHtml` +(`/bibliography/` pages). Verified on the rendered SIMD essay, including the +DOI-cited FIPS 203 entry resolving through its manifest alias. Details under +Link annotation — Bibliography. + +**Search-UI archive filter implemented (2026-06-10).** The last deferred +refinement with a code-shaped fix: the search page's filter panel gains an +"archive" mode (exclude / only) and a "link status" multi-select (live / +moved / rotted / error), backed by a new `data/archive-meta.json` emitted by +`Archive.hs` — the archive analogue of `epistemic-meta.json`. The collision +with the epistemic `status` filter is resolved by scoping (own state fields, +button classes, and labels), not renaming. Verified in headless Chrome. +Details in the Phase 5 Met note. + +--- + +## Motivation + +The site cites external work — papers, articles, blog posts, documentation. +Three things go wrong with a plain hyperlink over time: + +1. **Link rot.** The target moves, paywalls, or vanishes. A 2019 essay's + citations decay silently; nobody notices until a reader clicks. +2. **Content drift.** The target stays up but changes. The sentence you quoted + is no longer the sentence at that URL. +3. **Opacity to the site's own machinery.** An external link is invisible to + `Backlinks.hs` (`isPageLink` drops every `http(s)://` URL) and to + `embed.py` (it indexes only `_site/**/*.html`). The site knows nothing about + the things it most often points at. A paper cited by six essays has no page, + no backlinks list, no place in any "Related" set. + +The archive fixes all three by keeping a **local, hosted, immutable snapshot** +of each referenced work, giving it a stable URL on this domain, and making that +URL a first-class citizen of the existing backlinks and similar-pages systems. + +This is deliberately *not* a general web crawler. It archives a curated set: +the things this site references. The author adds a URL to a manifest; the build +does the rest. + +### Relationship to existing pieces + +| Existing piece | What it does | Why the archive is different | +|----------------|--------------|------------------------------| +| `static/papers/` | Hosts Levi's **own** typeset PDFs (`preprint:`, `{{pdf:}}`) | The archive holds **third-party** works. Distinct directory, distinct purpose. Never conflate the two. | +| nginx `popup-proxy.conf` | Caches **metadata** (title/abstract) from arXiv / archive.org / PubMed for hover previews | Caches structured metadata, not documents. A preview accelerator, not preservation. | +| `Backlinks.hs` | Inverts **internal** links into a "who links here" map | Indexes site content only; external URLs are dropped.

Archived works become site pages, so they enter the embedding corpus for free. | + +--- + +## Goals + +- **Preservation.** Every referenced work the author chooses to archive has a + byte-for-byte local snapshot that survives the original going dark. +- **Stable hosting.** Each snapshot is reachable at a permanent + `/archive/{slug}/` URL on levineuwirth.org, rendered in site chrome. +- **Hyperlink-able.** Archive URLs are ordinary internal links: usable in + prose, wikilinks, citations, and `further-reading`. +- **Indexed.** Archived works appear in the **backlinks** ("Referenced by") and + **similar-pages** ("Related") systems exactly as native content does — and, + where the source structure allows, granularly by section. +- **Curated, low-friction.** Adding an archive is one line in one manifest. + Everything else — fetch, text extraction, page generation, indexing — is + automatic and build-time. +- **Static-friendly.** Every archive page renders at build time; JS is layered + on, never required. Matches the rest of the site's contract. +- **Honest.** Archive pages never impersonate the original. They are framed as + archived copies, link prominently to the source, are kept out of search + engines, and carry a real, advertised removal channel on every page. +- **Safe by default.** No build step ever deletes or overwrites a committed + artifact; destruction and replacement are always explicit, opt-in acts. + +--- + +## Decisions (locked) + +| Topic | Decision | Rationale | +|-------|----------|-----------| +| Trigger | Curated manifest, not auto-crawl | Archives what the site *references*, not the web. Legally and operationally sane. | +| Authored input | One hand-edited file: `archive/manifest.yaml` | One line per archived link. Mirrors `data/commonplace.yaml`'s authoring model. | +| Bibliography seeding | **Rejected** as auto-seeding. `make archive-suggest` prints a "cited but not archived" diff; the author copies lines by hand. | Keeps the manifest the *identity* of the archive, not a cache of the `.bib` files. | +| Per-entry provenance | `archive/{slug}/PROVENANCE.json`, committed — immutable for the current snapshot | An immutability claim that isn't in version control isn't immutable. | +| Mutable state | `data/archive-state.json`, gitignored — link-rot status only | Strict split: immutable facts committed, volatile status disposable. | +| Hakyll input | `data/archive-index.json` — `url` + aliases → slug, written by the tool | Minimal stable shape for the Haskell side; treated like `data/annotations.json`. | +| Missing-index behaviour | `Backlinks.hs` and `Filters/Archive.hs` silently no-op when `archive-index.json` is absent | Preserves the established `.venv`-gated silent-skip convention. The archive degrades to invisible, never to an error. | +| `fetch` idempotence | `fetch` is keyed on `(slug, url)` together; a slug whose recorded URL has changed is refused, not overwritten. `fetch` always rewrites `archive-index.json` to mirror the manifest. | A committed artifact is replaced only by an explicit `refresh`, never as a `fetch` side effect. | +| Artifact storage | `archive/{slug}/` at repo root, **committed to git** | A preservation guarantee that depends on an un-versioned store is weaker. Repo stays reproducible. | +| Per-artifact size cap | 25 MB; `archive.py fetch` warns and skips above it; `git add -f` to override deliberately | A 200 MB scan must never land in an auto-commit silently. | +| Storage migration | If `archive/` exceeds ~5 GB or doubles year-over-year, evaluate a separate archive repo / object store. **Never git LFS.** | LFS breaks `git clone → make build` reproducibility — a regression for a preservation system. | +| HTML snapshots | `monolith -j` → one self-contained HTML file; the pinned `monolith` binary is committed at `tools/bin/monolith` | Single static binary, no headless browser. Strips JS. Committing it (vs downloading) removes a network dependency and keeps the build reproducible from a bare clone. | +| PDF snapshots | Direct download via `requests` | Papers are usually clean PDF URLs (arXiv etc.). | +| Display — PDF | The raw `document.pdf` in an `" + ++ "" + +-- | Percent-encode characters that would break a query-string value. +-- Slashes are left unencoded so root-relative paths remain readable and +-- work correctly with PDF.js's internal fetch. @#@ is encoded for +-- defense-in-depth even though the directive parser already splits on it +-- before this function is called. +encodeQueryValue :: String -> String +encodeQueryValue = concatMap enc + where + enc ' ' = "%20" + enc '&' = "%26" + enc '?' = "%3F" + enc '+' = "%2B" + enc '"' = "%22" + enc '#' = "%23" + enc c = [c] + diff --git a/build/Filters/Images.hs b/build/Filters/Images.hs new file mode 100644 index 0000000..5efac59 --- /dev/null +++ b/build/Filters/Images.hs @@ -0,0 +1,394 @@ +{-# LANGUAGE GHC2021 #-} +{-# LANGUAGE OverloadedStrings #-} +-- | Image filter: lazy loading, lightbox markers, WebP +-- wrappers, and CLS-preventing width/height attrs. +-- +-- For local raster images (JPG, JPEG, PNG, GIF) whose @.webp@ companion +-- exists on disk at build time, emits a @@ element with a WebP +-- @@ and the original format as the @@ fallback.

    + +--- +## Who is a website for? + +::: dropcap +It is a trick question. A website (at least, of the personal website type) is created and, in particular, shared with the world in the hopes that someone else will derive utility from it, whether that utility is diversion, knowledge, or something else. If I had something to say to myself, creating a website for it would be overkill, wouldn't it? +::: + +Yes and no, if you ask me. I believe in the power of transparency and honesty. If I am going to endeavor to accomplish something, making my attempt in the public eye is an excellent motivator and pushes me to be consistent. Similarly, if I have something that I feel is important to me, such as the content of this page, then I have yet to see a reason why I should not incorporate it into the website. Yes, the website is primarily a place for me to share works that I expressly create with the intent of sharing, but I have yet to see *any* detriment to additionally sharing works that I expressly create for my own consumption. I lose nothing, and have the possibility of gaining *something*, so this seems to me to be an instantiation of [Pascal's Wager](https://en.wikipedia.org/wiki/Pascal%27s_wager). + +## Applied Vanitas + +![Dante and Beatrice gaze upon the highest heaven.](/images/canto31.jpg "Gustav Doré - Paradiso, Canto 31") + +::: dropcap +Time passes regardless of our wishes, our intentions, our apprehensions.

Let +$\pi:V(H)\to V(G)$ have fibers of order at most $P$, and suppose that for a +scale factor $\lambda\ge1$ the distances between distinct fibers satisfy +\[ + \lambda(\dist_G(u,v)-1)+1 + \le \dist_H(x,y) + \le \lambda(\dist_G(u,v)+2)-2, +\] +while every fiber has diameter at most $2(\lambda-1)$. If the $N$-vertex +base graph has uniform multi-source growth at the square-root scale, then a +Hall assignment occupies a lifted macro-ball before the robber can leave it, +giving +\[ + \cnum(H)\le C P\bigl(d^3+\log(ePN)\bigr)\sqrt N +\] +and capture time at most $\lambda R$. The theorem uses only the displayed +projection properties, not the internal form of the fibers. + +Iterated degree reduction of Hosseini--Mohar--Gonzalez Hermosillo de la Maza +has exactly this geometry, with $\lambda=3^k$. Applied to +$G(N,p)$ of expected degree $(\log N)^4$, it yields connected subcubic graphs +of order $M$ with +\[ + h(H)\ge (\log M)^{-O(1)}, + \qquad + M^{\frac12-\frac{9+o(1)}{2\log\log\log M}} + \le \cnum(H) + \le \sqrt M\,(\log M)^{O(1)}. +\] +Thus the known stressing family has the square-root exponent, with a +polylogarithmically tight upper bound; the lower convergence to $1/2$ is only +triple-logarithmic. + +Finally, we prove a sharp limitation of the strategy class. If a common +prepositioned bank must, after learning a robber start $v$, match distinct cops +to every vertex of $B(v,R)$ using travel distance at most $R$, then +\[ + \Occ_R(G) + \ge + \frac{\sum_v |B(v,R)|}{\max_x |B(x,2R)|}. +\] +For every fixed $k\ge2$, the Cartesian torus $C_L^{\square k}$ has +$|V|=L^k$, vertex expansion $\Theta_k(L^{-1})$, exact cop number $k+1$, and +$\Occ_R=\Omega_k(L^k)$ for every radius $R$. Hence, for every $\delta>0$, +there are bounded-degree graphs with $h(G)\ge |G|^{-\delta}$ and constant cop +number on which one-shot occupation still costs a linear number of cops. A +cubic four-cycle replacement gives a degree-three instance at exponent +$\delta=1/2$. Any universal robustness theorem must therefore use adaptive +multi-round pursuit, cop reuse, or another strategy not reducible to one-shot +occupation. +\end{abstract} + +\maketitle + +\section{Introduction and main conclusions} + +The multi-cop version of Cops and Robber was developed by Aigner and Fromme, +who proved that three cops suffice on every planar graph +\cite{AignerFromme}. Meyniel's conjecture asks whether every connected +$n$-vertex graph has cop number $O(\sqrt n)$. The current best universal +upper bound remains +\[ + \frac{n}{2^{(1-o(1))\sqrt{\log_2 n}}}, +\] +proved independently by Lu--Peng and Scott--Sudakov +\cite{LuPeng,ScottSudakov}. Bose--Esperet--Hodor--Joret--Micek--Rambaud +recently extended the same scale of bound from graph order to vertex-cover +number \cite{CurrentFrontier}. Expansion is one of the principal settings in +which polynomial savings are known: Bradshaw--Hosseini--Mohar--Stacho obtain +weak Meyniel bounds from bounded-degree expansion restricted to sublinear set +scales \cite{BHMS}, while Clow's withdrawn preprint developed a closely +related structural program connecting failure of weak Meyniel to high-cop +expanding examples \cite{Clow}. + +The motivation here is the effect of bounded-degree replacement gadgets on +pursuit. The degree-reduction construction of Hosseini--Mohar--Gonzalez +Hermosillo de la Maza (HMGHM) preserves lower bounds on cop number and +produces subcubic graphs with cop number $M^{1/2-o(1)}$ \cite{HMGHM}. A +natural converse question is whether a useful upper strategy on the base +graph survives the replacement tower. + +An arbitrary winning strategy does not lift transparently. Moving one step +in the quotient may require a squad dispersed through a cloud to reorganize +while the robber continues moving. The successful object is narrower and +more stable: an \emph{occupation certificate} that assigns distinct cops to +all vertices of a region before the robber can leave it. Distance stretching +slows both deployment and escape, and a bounded normalized additive error +leaves a strict timing margin. + +The first result is therefore stated for an abstract projection, rather than +for the HMGHM gadget. The gadget enters only later, through an exact metric +calculation. The resulting upper bound is stronger quantitatively than the +notation $M^{1/2+o(1)}$ suggests: it is $\sqrt M$ times a polylogarithmic +factor. By contrast, the available lower bound approaches the square-root +exponent at the triple-logarithmic rate displayed in the abstract. These two +facts should not be conflated merely because both can be written +$M^{1/2+o(1)}$. + +The final result marks the boundary of the mechanism. A one-shot occupation +certificate needs polynomial ball amplification between radii $R$ and $2R$. +Polynomially weak expansion alone does not supply this. For every fixed +$k$, the Cartesian tori $C_L^{\square k}$ have bounded metric doubling, exact +cop number $k+1$, and linear one-shot occupation cost at every radius. Taking +$k>1/\delta$ puts these examples inside every window +$h(G)\ge |G|^{-\delta}$. A separate cubic replacement retains the barrier at +$\delta=1/2$. The obstacle in the universal problem is therefore not degree +reduction itself; it is the need for adaptive reuse over many weak-growth +layers. + +\section{Scale-adaptive cores and the robustness window} + +For a connected graph $J$, write +\[ + h(J)=\min_{\varnothing\ne A\subseteq V(J),\ |A|\le |J|/2} + \frac{|\partial_J A|}{|A|}. +\] +The following elementary reduction explains why polynomially weak expansion +is the relevant robustness window for the universal problem. + +\begin{proposition}[Scale-adaptive induced core]\label{prop:adaptive-core} +Let $J$ be a connected graph of order $n$, and let +$\eta(1)\ge\cdots\ge\eta(n)\ge0$. Then $J$ contains a connected induced +subgraph $K$, of order $m$, such that +\[ + \boxed{h(K)\ge\eta(m)} + \qquad\text{and}\qquad + \boxed{\cnum(J)\le \cnum(K)+\sum_{j=m+1}^{n}\eta(j).} +\] +\end{proposition} + +\begin{proof} +Maintain the connected induced region $J_i$ containing the robber. Whenever +$|J_i|=m_i$ and $h(J_i)<\eta(m_i)$, choose +$A_i\subseteq V(J_i)$ with $0<|A_i|\le m_i/2$ and +$|\partial_{J_i}A_i|<\eta(m_i)|A_i|$, and occupy its boundary. The robber is +then confined to one component $J_{i+1}$ of +$J_i-\partial_{J_i}A_i$. Whether that component lies inside $A_i$ or outside +it, one has +\[ + |A_i|\le m_i-m_{i+1}. +\] +Consequently the separator costs at most +\[ + \eta(m_i)(m_i-m_{i+1}) + \le + \sum_{j=m_{i+1}+1}^{m_i}\eta(j). +\] +These integer intervals are disjoint along the robber's nested component +chain. The process terminates at a connected induced $K$ with +$h(K)\ge\eta(|K|)$, and the separator costs telescope to the displayed sum. +\end{proof} + +Taking $\eta(j)=j^{-a}$ shows that a polynomial cop-number saving on +subcubic graphs with $h(K)\ge |K|^{-a}$ would imply a weak form of Meyniel for +arbitrary graphs after the bounded-degree transfer of +Hosseini--Mohar--Gonzalez Hermosillo de la Maza +\cite[Corollary~8]{HMGHM}. Bradshaw--Hosseini--Mohar--Stacho already treat +constant expansion restricted to sublinear set scales \cite{BHMS}; the +unresolved axis in this reduction is expansion that itself shrinks +polynomially. + +\section{Coarse occupation projections} + +\begin{definition}[Coarse occupation projection]\label{def:projection} +Let $G$ and $H$ be connected graphs. A surjection +$\pi:V(H)\to V(G)$ is a $(\lambda,P)$-occupation projection if, writing +$F_v=\pi^{-1}(v)$, +\begin{enumerate}[label=\textup{(\roman*)}] +\item $|F_v|\le P$ for every $v\in V(G)$; +\item for distinct $u,v\in V(G)$ and arbitrary $x\in F_u$, $y\in F_v$, +\[ + \lambda(\dist_G(u,v)-1)+1 + \le + \dist_H(x,y) + \le + \lambda(\dist_G(u,v)+2)-2; +\] +\item $\diam_H(F_v)\le2(\lambda-1)$ for every $v\in V(G)$. +\end{enumerate} +\end{definition} + +The particular constants in Definition~\ref{def:projection} are chosen because they are +exact for the HMGHM tower. The proof below only needs a bounded additive +slack after division by $\lambda$ and a strict gap between deployment and +escape deadlines. + +For $U\subseteq V(G)$, let $B_G(U,r)$ be its closed radius-$r$ +neighborhood. + +\begin{theorem}[Abstract macro-ball occupation transfer]\label{thm:abstract-transfer} +Let $G$ have $N$ vertices. Fix $d\ge2$, $R\ge2$, and constants $a,A_0>0$. +Assume +\begin{equation}\label{eq:scale} + \sqrt N\le d^{R-2}\frac{\sqrt N}{d}\ge N^{1/3}, +\] +so the polynomial prefactors are negligible. + +Hall's condition therefore holds simultaneously for all macro-balls with +probability $1-o(1)$. The total number of sampled tokens is at most +$2AP\Theta\sqrt N$ with probability $1-o(1)$, so a deterministic placement of +the claimed size exists. + +It remains to compare deadlines. A target $y\in X_v$ lies over some +$u\in B_G(v,R)$. Its assigned cop begins over $z$ with +$\dist_G(z,u)\le R-2$. If $z\ne u$, the upper distortion bound gives travel +time at most +\[ + \lambda((R-2)+2)-2=\lambda R-2. +\] +If $z=u$, the fiber-diameter bound gives at most +$2(\lambda-1)\le\lambda R-2$, since $R\ge2$. + +To leave $X_v$, the robber must enter a fiber over a base vertex at distance +at least $R+1$ from $v$. The lower distortion bound makes this require at +least +\[ + \lambda((R+1)-1)+1=\lambda R+1 +\] +steps. Every vertex of $X_v$ is occupied first, and the cop assigned to the +robber's current vertex captures her. +\end{proof} + +\begin{remark}[The quantifier needed from the random base]\label{rem:PW-uniform} +The use of \eqref{eq:lowergrowth} is graph-uniform, not a per-source-set +probability statement. In the dense theorem of Pra{\l}at and Wormald, +condition~(i) of their deterministic Theorem~3.1 is explicitly quantified over +\emph{every} source set and radius. Their Theorem~3.4 proves that a single +$G(N,p)$ satisfies those hypotheses asymptotically almost surely; its proof +unions over the bad source sets and concludes that the growth estimate holds +simultaneously for all sets and radii \cite[Theorems~3.1 and~3.4]{PW}. +Thus the external input has the quantifier order required by +\cref{thm:abstract-transfer}. +\end{remark} + +\section{The HMGHM replacement tower} + +For a vertex of degree $r$, the HMGHM replacement has one external port for +every incident edge. The ports are partitioned into nearly equal classes, +and for each pair of classes there is an internal vertex adjacent to every +port in the two classes \cite[Section~2]{HMGHM}. + +\begin{lemma}[One-round port geometry]\label{lem:portgeometry} +For every HMGHM replacement cloud of degree at least two: +\begin{enumerate}[label=\textup{(\roman*)}] +\item distinct ports are nonadjacent and have distance exactly two; +\item every cloud vertex is within distance at most three of every specified +port; +\item the cloud diameter is at most four. +\end{enumerate} +\end{lemma} + +\begin{proof} +Two ports in different classes share the internal vertex associated with +their class pair. Two ports in the same class share any internal vertex +associated with that class and another nonempty class. Since ports are +mutually nonadjacent, their distance is exactly two. + +An internal vertex is adjacent to every port in either of two classes. If a +specified port lies in neither class, travel to a port in one of the two +classes, then through the internal vertex corresponding to that class and the +specified port's class, and finally to the specified port. This takes three +steps. The diameter bound follows by routing arbitrary endpoints through a +specified port. +\end{proof} + +Let +\[ + G=G_0,G_1,\ldots,G_k=H +\] +be an iterated HMGHM tower, and let $\pi:V(H)\to V(G)$ map every final vertex +to its original ancestor. Put +\[ + F_v=\pi^{-1}(v), + \qquad + P=\max_v|F_v|, + \qquad + \lambda=3^k. +\] + +\begin{theorem}[Exact normalized distortion]\label{thm:metric} +The ancestry projection is a $(3^k,P)$-occupation projection. Explicitly, +for distinct base vertices $u,v$, $r=\dist_G(u,v)$, and arbitrary +$x\in F_u$, $y\in F_v$, +\[ + \boxed{ + 3^k(r-1)+1 + \le + \dist_H(x,y) + \le + 3^k(r+2)-2, + } +\] +and +\[ + \boxed{\diam_H(F_v)\le2(3^k-1).} +\] +\end{theorem} + +\begin{proof} +For one round, a shortest path between distinct clouds uses $e\ge r$ +external edges. Between consecutive external edges it enters and leaves an +intermediate cloud through distinct ports: otherwise it immediately traverses +one external edge back. By Lemma~\ref{lem:portgeometry}, each intermediate port +change costs at least two internal edges, and hence +\[ + \dist_{G_1}(x,y)\ge e+2(e-1)\ge3r-2. +\] +For the upper bound, follow a base geodesic. Reaching the first prescribed +port costs at most three, each intermediate port change costs two, the +external edges cost $r$, and reaching the final endpoint costs at most three. +Thus +\[ + \dist_{G_1}(x,y)\le3+r+2(r-1)+3=3r+4. +\] +The one-round fiber diameter is at most four. + +The lower and upper affine recurrences are +\[ + L_j(r)=3L_{j-1}(r)-2, + \qquad + U_j(r)=3U_{j-1}(r)+4, +\] +with $L_0(r)=U_0(r)=r$. Solving gives +\[ + L_k(r)=3^k(r-1)+1, + \qquad + U_k(r)=3^k(r+2)-2. +\] +The diameter recurrence $D_j\le3D_{j-1}+4$, $D_0=0$, gives +$D_k\le2(3^k-1)$. +\end{proof} + +The feature that matters is not the number of rounds but the normalized +additive error: after division by $3^k$, it remains two quotient layers. By +\cref{thm:abstract-transfer}, any other graph projection with the same three +properties inherits the same occupation-certificate transfer. + +\section{Expansion retention under port-cloud replacement} + +\begin{proposition}[Expansion under connected port replacement]\label{prop:port-exp} +Let $H$ be obtained from a base graph $G$ by replacing every vertex by a +connected cloud of order at most $L_0$, with distinct external ports for the +incident base edges. If $\iotae(G)$ is the edge-isoperimetric constant of +$G$, then +\[ + \boxed{ + \iotae(H) + \ge + \frac{1}{2L_0} + \min\left\{1,\frac{\iotae(G)}{L_0}\right\}. + } +\] +\end{proposition} + +\begin{proof} +Let $S\subseteq V(H)$ with $0<|S|\le|H|/2$. In each cloud, classify the +majority side and let $\mathcal M$ be the total number of minority vertices. Since +every partially cut cloud is connected and has at most $L_0$ vertices, its +internal cut contributes at least one edge, so the total internal contribution +is at least $\mathcal M/L_0$. + +Let $U$ be the set of base vertices whose clouds have majority in $S$, and +put $E=e_G(U,V(G)\setminus U)$. A base cut edge can fail to cross the lifted +cut only if one of its two ports is a minority vertex. Distinct base edges +use distinct ports, so at most $\mathcal M$ of the $E$ external cut edges fail. Hence +\[ + e_H(S,V(H)\setminus S) + \ge + \frac{\mathcal M}{L_0}+\max\{0,E-\mathcal M\} + \ge + \frac{E+\mathcal M}{2L_0}. +\] +Apply the same majority accounting to $S$ or its complement, according as +$|U|\le|G|/2$ or not, to obtain +\[ + \min\{|U|,|V(G)\setminus U|\} + \ge + \frac{|S|-\mathcal M}{L_0}. +\] +Thus +\[ + E\ge\frac{\iotae(G)}{L_0}(|S|-\mathcal M), +\] +and consequently +\[ + E+\mathcal M + \ge + \min\left\{1,\frac{\iotae(G)}{L_0}\right\}|S|. +\] +Combining the inequalities proves the proposition. +\end{proof} + +The HMGHM cloud-size recurrence turns the one-round estimate into a +subpolynomial-loss statement in the polylogarithmic-degree regime. If $D$ +is the initial maximum degree, $L_i$ is the largest cloud order in round $i$, +and $k$ rounds are used, HMGHM prove +\[ + \prod_{i=0}^{k-1}L_i + \le C D^2(\log D)^{\log_2(11/5)}, + \qquad + 2^k=O(\log D). +\] +Iterating Proposition~\ref{prop:port-exp} therefore gives the following. + +\begin{corollary}[Expansion retained by HMGHM reduction]\label{cor:exp-retention} +Let $H$ be the final subcubic graph obtained from a connected graph $G$ of +maximum degree $D\ge4$. Then +\[ + \boxed{ + h(H) + \ge + \frac{\iotae(G)}{C D^4(\log D)^{\kappa}}, + \qquad + \kappa=1+2\log_2(11/5)<3.28. + } +\] +In particular, if $D=|G|^{o(1)}$ and $\iotae(G)=|G|^{-o(1)}$, then +$|H|=|G|^{1+o(1)}$ and $h(H)=|H|^{-o(1)}$. +\end{corollary} + +\begin{proof} +At every round $\iotae(G_i)\le D_i\le L_i$, so +Proposition~\ref{prop:port-exp} gives +\[ + \iotae(G_{i+1})\ge\frac{\iotae(G_i)}{2L_i^2}. +\] +Thus +\[ + \iotae(H) + \ge + \frac{\iotae(G)}{2^k(\prod_iL_i)^2} + \ge + \frac{\iotae(G)}{C D^4(\log D)^\kappa}. +\] +Since $H$ has maximum degree at most three, its vertex expansion is at least +one third of its edge expansion. The order statement follows from the same +cloud-product bound. +\end{proof} + +\begin{remark}[Relation to replacement products] +The regular replacement-product literature proves stronger spectral +conclusions under much stronger hypotheses on the clouds; see, for example, +Reingold--Vadhan--Wigderson \cite{RVW}. Proposition~\ref{prop:port-exp} allows arbitrary +connected, nonuniform clouds and consequently gives only a crude +isoperimetric estimate. No novelty claim is made here beyond this precise +form without a fuller graph-substitution review. +\end{remark} + +\section{A polylogarithmically tight square-root family} + +Take +\[ + d=(\log N)^4, + \qquad + p=\frac{d}{N-1}, + \qquad + G\sim G(N,p). +\] +Iterate the HMGHM replacement until the graph $H$ is subcubic, and write +$M=|H|$. + +With high probability, $\Delta(G)\le2d$. By +Remark~\ref{rem:PW-uniform}, the dense Pra{\l}at--Wormald theorem supplies the +uniform lower growth in \eqref{eq:lowergrowth}; in the volume range used here +it also supplies the upper growth in \eqref{eq:uppergrowth} \cite{PW}. Choose +$R$ minimally so that $d^{R-2}\ge\sqrt N$. Since $d$ is polylogarithmic, +\eqref{eq:scale} holds. + +HMGHM give, both globally and along one ancestry fiber, +\begin{equation}\label{eq:Pbound} + P\le C d^2(\log d)^{1.14}, + \qquad + N\le M\le PN. +\end{equation} +Their shadow strategy gives $\cnum(H)\ge\cnum(G)$, and the random-graph lower +bound of Bollob\'as--Kun--Leader used in their argument yields +\[ + \cnum(G) + \ge + d^{-2}N^{\frac12-\frac{9}{2\log\log d}}. +\] +The abstract transfer theorem gives +\[ + \cnum(H) + \le + CP\bigl(d^3+\log(ePN)\bigr)\sqrt N + \le + \sqrt M\,(\log M)^{20+o(1)}. +\] +Using $d=(\log N)^4$ and $M=N(\log N)^{O(1)}$ in the lower bound gives the +following more informative formulation. + +\begin{theorem}[Quantitative HMGHM hard family]\label{thm:hardfamily} +There is a sequence of connected subcubic graphs $H$, of order $M\to\infty$, +for which +\[ + \boxed{ + M^{\frac12-\frac{9+o(1)}{2\log\log\log M}} + \le + \cnum(H) + \le + \sqrt M\,(\log M)^{20+o(1)}. + } +\] +The upper bound is $\sqrt M$ times a polylogarithmic factor. The lower +exponent tends to $1/2$ only at a triple-logarithmic rate. +\end{theorem} + +The base edge expansion is $\Omega(d)$ with high probability. Since +$d=\operatorname{polylog}N$, Corollary~\ref{cor:exp-retention} gives +\[ + h(H)\ge (\log M)^{-O(1)}=M^{-o(1)}. +\] +This is exactly the degree regime in which the retention factor is +informative; for polynomial initial degree the crude $D^4$ loss can be +vacuous. + +\begin{corollary}[Square-root weak-expander family]\label{cor:weakexpander} +There are connected subcubic graphs satisfying +\[ + h(H)\ge M^{-o(1)} + \qquad\text{and}\qquad + \cnum(H)=M^{1/2+o(1)}. +\] +More precisely, they obey the two-sided bounds of +\cref{thm:hardfamily}. +\end{corollary} + +\begin{remark}[What is forced, and what is achieved]\label{rem:robustness-endpoint} +By \cref{prop:adaptive-core}, polynomially weak expansion is a natural +robustness window for weak Meyniel. The HMGHM lower bound alone already +forces every proposed estimate +\[ + \cnum(J)\le C\phi^{-p}|J|^{1-\eps+o(1)} + \qquad(h(J)\ge\phi=|J|^{-o(1)}) +\] +to have $\eps\le1/2$. That restriction predates the upper transfer proved +here. The new conclusion is that the known stressing family itself achieves +the endpoint order $\sqrt M$ up to polylogarithmic factors, so this family is +not an obstruction to a Meyniel-strength theorem on polynomially weak +subcubic expanders. +\end{remark} + +\section{Why chase strategies need not transfer} + +The abstract theorem deliberately transfers a strategy class, not arbitrary +cop number. The smallest example explains the distinction. For a degree-two +vertex, one HMGHM cloud is a three-vertex path. Replacing every vertex of +$C_3$ therefore produces $C_9$. But +\[ + \cnum(C_3)=1, + \qquad + \cnum(C_9)=2. +\] +The one-cop win on $C_3$ is a direct chase/dismantling phenomenon. The +subdivision-like stretching destroys it. By contrast, an occupation +certificate is synchronized to a deadline: the replacement tower stretches +the cops' travel and the robber's escape by the same factor, and the bounded +normalized additive slack preserves a strict margin. The examples +$K_4$ and the diamond graph exhibit the same one-round increase, so the issue +is structural rather than peculiar to one cycle. + +\section{A one-shot occupation barrier} + +\begin{definition}[Universal one-shot occupation number]\label{def:occ} +For a connected graph $G$ and integer $R\ge0$, let $\Occ_R(G)$ be the minimum +size of a finite set $X$ of distinct cop tokens, equipped with a position map +$p:X\to V(G)$, such that for every $v\in V(G)$ there is an injection +\[ + f_v:B_G(v,R)\longrightarrow X +\] +with +\[ + \dist_G(u,p(f_v(u)))\le R + \qquad\text{for every }u\in B_G(v,R). +\] +Different tokens may have the same initial position. After learning the +robber's starting vertex, the common prepositioned bank can occupy her entire +radius-$R$ ball within $R$ moves. +\end{definition} + +\begin{remark}[Why the target and deadline are natural] +If the robber starts at $v$, she needs at least $R+1$ robber moves to leave +$B_G(v,R)$. Occupying that whole ball within $R$ cop moves is therefore the +canonical one-shot certificate: every vertex she could still occupy is filled +before her first possible escape. The parameter $\Occ_R$ measures this +specific strategy class, not ordinary cop number. +\end{remark} + +\begin{theorem}[Counting barrier]\label{thm:occ-lower} +Every connected graph satisfies +\[ + \boxed{ + \Occ_R(G) + \ge + \frac{\sum_{v\in V(G)}|B_G(v,R)|} + {\max_{x\in V(G)}|B_G(x,2R)|}. + } +\] +In particular, if $G$ is vertex-transitive, then +\[ + \boxed{ + \Occ_R(G) + \ge + |V(G)|\frac{|B_G(o,R)|}{|B_G(o,2R)|}. + } +\] +\end{theorem} + +\begin{proof} +Fix a feasible multiset $X$. For each possible robber start $v$, every cop +token used by the injection $f_v$ lies in $B_G(v,2R)$, by the triangle +inequality. Hence at least $|B_G(v,R)|$ tokens of $X$ lie in $B_G(v,2R)$. +Summing over $v$, the number of incident pairs $(v,x)$ with +$x\in X\cap B_G(v,2R)$ is at least +$\sum_v|B_G(v,R)|$. + +A fixed token based at $x$ is counted only for starts +$v\in B_G(x,2R)$, at most $\max_y|B_G(y,2R)|$ times. Therefore +\[ + |X|\max_y|B_G(y,2R)| + \ge + \sum_v|B_G(v,R)|, +\] +which proves the claim. +\end{proof} + +The theorem identifies the exact growth ratio demanded by one-shot +occupation.

An endpoint-sensitive geodesic lemma shows that, among possibly infinite $d$-regular graphs, radius $R+t$ is sharp for arbitrary pairs in $B_R(v_0)\times B_t(v_0)$, while synchronized witnesses along a prescribed path require only a radius-$R$ tree-ball. If every tube is occupied, each surviving round along every path in this class ends in capture, blockage, or branch-load support on at least two branches. The tubes partition the outer ball, so deterministic coverage has minimum cost $N_t=d(d-1)^{t-1}$; conditional on a specified root, i.i.d.\ uniform coverage has threshold $\Theta(N_t\log N_t)$ for fixed $d$. An augmented prefix-depth profile that retains the complete shallow configuration still need not determine later support. The result is local and root-dependent: it treats neither arbitrary robber walks nor a robber-independent cop strategy, and it gives no cop-number bound. +\end{abstract} + +\maketitle + + +\section{Introduction} + +\subsection{Motivation} + +The cops-and-robbers game, introduced independently in its one-cop form by Quilliot and by Nowakowski--Winkler and developed in its multiple-cop form by Aigner--Fromme~\cite{Quilliot,NowakowskiWinkler,AignerFromme}, is a pursuit-evasion game on a graph in which $k$ cops attempt to capture one robber. The minimum such $k$ is the \emph{cop number} $c(G)$. \emph{Meyniel's conjecture}, attributed to Henri Meyniel and appearing in the early literature in Frankl's work~\cite{Frankl}, asserts that $c(G)=O(\sqrt n)$ for every connected graph on $n$ vertices and remains a central open problem in the area. The best general upper bound, +\[ +c(G) \leq \frac{n}{2^{(1-o(1))\sqrt{\log_2 n}}}, +\] +was proved independently by Lu--Peng, Scott--Sudakov, and Frieze--Krivelevich--Loh~\cite{LuPeng,ScottSudakov,FriezeKrivelevichLoh}. + +Pra\l at--Wormald's random-graph argument combines an initial random cop placement with assignments made after the robber's start is revealed: in different regimes, cop teams fully occupy a neighborhood or densely cover a sphere~\cite{PralatWormald}. Tree-like geometry enters the literature in several other ways. Aigner--Fromme show that one moving cop can guard a fixed isometric path~\cite{AignerFromme}. Frankl established a high-girth lower bound~\cite{Frankl}, and Bradshaw--Hosseini--Mohar--Stacho refine that line through a branch-weight argument in which unique local geodesics let the robber choose a sufficiently lightly controlled forward branch~\cite{BradshawHosseiniMoharStacho}. Related bounded-degree reductions provide broader extremal context~\cite{HMG}. These mechanisms motivate a path-conditioned local question: whether cops near the robber can coordinate their distance-decreasing moves along every prescribed length-$t$ nonbacktracking path starting at the robber's initial vertex. + +The present paper instead isolates one rigid, root-dependent certificate: every length-$t$ nonbacktracking path from $v_0$ indexes an occupied descendant tube. Paths here index a static partition of the outer ball rather than a route guarded by one moving cop or an adaptively selected escape branch. We determine this certificate's guarantee and cost. Arbitrary robber walks, including stationary moves and reversals, are not analyzed, and exact tree geometry is not asserted to be necessary. + +The uniform sampling below is conditional on the fixed root $v_0$: the root is specified before cop positions are sampled from $B_R(v_0)$. This measures the local cost of the certificate, not a legal initial placement in the standard game, where cops choose positions before the robber chooses its start. A global strategy would need comparable coverage simultaneously or adaptively for an unknown robber position. Accordingly, the results neither construct a robber-independent global strategy nor improve the cop-number bound. + +\subsection{Setup and endpoint-sensitive tree-ball geodesics} + +Graphs are simple and undirected. The local results allow finite or infinite graphs unless finiteness is stated explicitly; discussion of the cop number and all $n$-vertex asymptotics concerns finite connected graphs. Throughout, $G$ denotes a $d$-regular graph with $d\geq3$, and $v_0\in V(G)$ is the robber's initial position in the rooted local experiment. All radii and time horizons are nonnegative integers, and $t,r\geq1$ whenever length-$t$ or order-$r$ objects are used. All unadorned logarithms are natural. We write +\[ +B_R(v)=\{x\in V(G):\dist(x,v)\leq R\}, +\qquad +S_j(v)=\{x\in V(G):\dist(x,v)=j\}. +\] + +\begin{definition}[Tree-ball] +\label{def:tree-ball} +The ball $B_R(v_0)$ is a \emph{tree-ball} if the induced subgraph $G[B_R(v_0)]$ is a tree. +\end{definition} + +This is a local condition at the specified center. The global condition $\operatorname{girth}(G)>2R+1$ implies that every radius-$R$ ball is a tree-ball. Conversely, if every radius-$R$ ball is a tree-ball, then $\operatorname{girth}(G)>2R+1$. + +An induced tree-ball does not control shortest paths between arbitrary pairs of its vertices: a competing path may leave the ball and re-enter. The required radius depends on the endpoint depths and on the length of their path inside the tree-ball. + +\begin{lemma}[Endpoint-sensitive tree-ball geodesics] +\label{lem:buffer} +Suppose $B_q(v_0)$ is a tree-ball, let $x,y\in B_q(v_0)$, and let $L$ be the length of the $x$--$y$ path in $G[B_q(v_0)]$. If +\[ +\dist(x,v_0)+\dist(y,v_0)+L\leq 2q, +\] +then every ambient $x$--$y$ geodesic lies in $B_q(v_0)$. Consequently, that geodesic is unique and equals the $x$--$y$ path in $G[B_q(v_0)]$. +\end{lemma} + +\begin{proof} +Let $P$ be an ambient $x$--$y$ geodesic of length $\ell$. The path in $G[B_q(v_0)]$ gives $\ell\leq L$. For $z\in P$, write $h=\dist_P(x,z)$. Then +\[ +\dist(z,v_0) +\leq \min\{\dist(x,v_0)+h,\ \dist(y,v_0)+\ell-h\} +\leq \frac{\dist(x,v_0)+\dist(y,v_0)+\ell}{2} +\leq q. +\] +Thus $P\subseteq B_q(v_0)$. Since the induced graph on this ball is a tree, $P$ is its unique $x$--$y$ path. +\end{proof} + +\begin{remark}[Uniform buffers versus chase endpoints] +For arbitrary $x\in B_R(v_0)$ and $y\in B_t(v_0)$, the walk from $x$ to $y$ through $v_0$ has length at most $R+t$. If $B_{R+t}(v_0)$ is a tree-ball, the path between $x$ and $y$ in the rooted tree $G[B_{R+t}(v_0)]$ is no longer than this walk, so Lemma~\ref{lem:buffer} applies. For $R,t\geq1$, this uniform radius cannot in general be reduced. Put $L=R+t$, begin with the rooted $d$-regular tree truncated at depth $L-1$, and choose vertices $x$ and $y$ at depths $R$ and $t$ in distinct root branches. Choose descendants $a$ of $x$ and $b$ of $y$ in $S_{L-1}(v_0)$, allowing equality, add a new vertex $z$, and join $z$ to $a$ and $b$. + +Complete the graph explicitly: for each remaining degree deficit at a vertex of $S_{L-1}(v_0)\cup\{z\}$, attach by one edge a separate infinite rooted $(d-1)$-ary tree. Every vertex then has degree $d$, and the resulting graph is infinite, simple, and connected. The induced ball $B_{L-1}(v_0)$ is still the original tree. The path from $x$ to $y$ through $v_0$ has length $L$, while the path through $z$ has length +\[ +\dist(x,a)+2+\dist(b,y)=(t-1)+2+(R-1)=L. +\] +Each attached infinite tree meets the displayed core at only one vertex, so it creates no additional route between $x$ and $y$. Thus the two displayed paths are distinct geodesics. This proves sharpness at radius $R+t-1$ among possibly infinite $d$-regular graphs. + +The endpoint pairs used along a prescribed length-$t$ nonbacktracking path are more restricted. Their rooted-tree path and endpoint depths satisfy Lemma~\ref{lem:buffer} with $q=R$, so the persistence result requires no tree-ball beyond the cop-placement radius. This does not assert that the radius-$R$ tree-ball hypothesis is necessary. Controlled cyclic geometry is not addressed here, and no cyclic extension is proved. +\end{remark} + +Whenever $B_q(v_0)$ is a tree-ball, we root $G[B_q(v_0)]$ at $v_0$. Every vertex other than $v_0$ has a unique parent, and every vertex of depth less than $q$ has $d-1$ children. + +\begin{definition}[Geodesic cone] +\label{def:cone} +Suppose $B_r(v)$ is a tree-ball and $u\in N(v)$. The \emph{geodesic cone} through $u$ at radius $r$ is +\[ +C_u(v,r):=\{x\in B_r(v)\setminus\{v\}:\text{the path from $x$ to $v$ in $B_r(v)$ has penultimate vertex $u$}\}. +\] +\end{definition} + +\begin{definition}[Path tube] +\label{def:tube} +Let $R\geq t$, suppose $B_R(v_0)$ is a tree-ball, and let +\[ +\sigma=(v_0,v_1,\ldots,v_t) +\] +be a length-$t$ nonbacktracking path starting at $v_0$: consecutive vertices are adjacent and $v_{i+1}\neq v_{i-1}$ whenever the latter condition is defined. The \emph{length-$t$ tube} associated with $\sigma$ is +\[ +T_\sigma(R):=\{x\in B_R(v_0):\text{the rooted path from $x$ to $v_0$ contains $v_t,v_{t-1},\ldots,v_1$ in order}\}. +\] +Equivalently, $T_\sigma(R)$ is the set of descendants of $v_t$ lying in $B_R(v_0)$. +\end{definition} + +\subsection{Game conventions} + +A \emph{cop configuration} $X$ is a finite multiset of vertices, represented by its finitely supported multiplicity function $X(v)\in\mathbb Z_{\geq0}$. For $A\subseteq V(G)$, set +\[ +X(A):=\sum_{v\in A}X(v), +\qquad +|X|:=X(V(G)), +\qquad +\supp(X):=\{v:X(v)>0\}. +\] +Thus counts of cops include multiplicity, several cops may occupy one vertex, and $A$ is occupied exactly when $X(A)>0$. We write $X=[x_1,\ldots,x_k]$ for a multiset of cop positions, with repeated entries allowed. Independent uniform sampling is with replacement and produces the multiset of sampled positions. + +Capture occurs whenever a cop and the robber occupy the same vertex, including before the first cop move; once capture occurs, no further move is made. Conditional on no capture, the cops move first in each round, simultaneously, and each cop moves to a neighboring vertex minimizing its distance to the robber's current vertex. Ties may be broken arbitrarily. Some formulations also allow cops to pass; the results remain valid there by having the selected witnesses make the prescribed distance-decreasing moves. Under the tree-ball hypotheses below, Lemma~\ref{lem:buffer} shows that each witness selected in our proofs has a unique distance-decreasing move. + +We analyze only length-$t$ nonbacktracking robber paths starting at $v_0$. In the full game a robber walk may reverse an edge or, under common conventions, remain stationary. Neither behavior is covered here. Fix a prescribed path +\[ +\tau=(v_0,v_1,\ldots,v_t). +\] +It survives through round $0$ precisely when no initial capture occurs. If it has survived through round $s-1$, then the robber is at $v_{s-1}$ when round $s$ begins. After the cops move toward $v_{s-1}$, the robber is captured if a cop occupies $v_{s-1}$. Otherwise the prescribed move $v_{s-1}\to v_s$ is \emph{legal} if no cop occupies $v_s$ after the cop move. The path survives through round $s$ if no capture or blockage has occurred through that move. + +For a robber position $v$ and a neighbor $u\in N(v)$, an individual cop at $c\neq v$ whose $c$--$v$ geodesic is unique \emph{contributes to branch $u$ at $v$} if that geodesic has penultimate vertex $u$. The \emph{branch-load support} at $v$ is the set of branches receiving at least one contributing cop; its size counts branches, not cops. + +\subsection{Main results and scope} + +Although $R+t$ is the sharp uniform radius for arbitrary endpoint pairs in $B_R(v_0)\times B_t(v_0)$, the synchronized pairs arising along a prescribed length-$t$ nonbacktracking path satisfy the endpoint-sensitive criterion already at radius $R$. Accordingly, the persistence theorem assumes only that the cop-placement ball $B_R(v_0)$ is a tree-ball. + +Exact rooted-tree counts identify first-level cones as the $t=1$ path tubes and show that the length-$t$ tubes partition the outer ball. Conditional on the prescribed path continuing, a witness's initial depth determines a potential capture or blockage time within the horizon or certifies descendant pressure throughout it. This yields a persistence theorem uniform over all length-$t$ nonbacktracking paths starting at $v_0$, and only over that class. + +The next results quantify the price of exhaustive static coverage. Exactly +\[ +N_t=d(d-1)^{t-1} +\] +cops are necessary and sufficient to occupy every tube at a fixed root. Along fixed-degree sequences with $t\to\infty$, conditional uniform sampling has a threshold of order $N_t\log N_t$; its leading factor depends explicitly on $R-t$ and tends to $1$ when $R-t\to\infty$. + +Finally, Section~\ref{sec:profile-loss} records information lost by finite-order tube profiles. Even after retaining every shallow cop multiplicity, such a profile need not determine branch support after $r+1$ rounds. This exact nondeterminacy does not rule out one-sided certificates that reject ambiguous profile fibers. + +\section{Cone and Tube Counts} + +\begin{lemma}[Sharp shell and cone counts] +\label{lem:shell} +Let $G$ be $d$-regular with $d\geq3$, and suppose $B_r(v)$ is a tree-ball.

Its level $j-1$ contains $(d-1)^{j-1}$ vertices, giving the first formula. Summing over the $d$ branches gives the shell count, and the remaining identities follow by summing the geometric series. +\end{proof} + +For $t=1$, geodesic cones are exactly the path tubes. We now count the general length-$t$ objects that drive the persistence argument. + + +\begin{lemma}[Tube count and partition] +\label{lem:tube-partition} +Let $R\geq t$, and suppose $B_R(v_0)$ is a tree-ball.

Their number is +\[ +N_t=d(d-1)^{t-1}. +\] +\end{lemma} + +\begin{proof} +At total depth $j\geq t$, the descendants of the terminal vertex $v_t$ form the depth-$(j-t)$ level of a $(d-1)$-ary rooted tree and hence contribute $(d-1)^{j-t}$ vertices. Summing gives the tube size. + +Every vertex of depth at least $t$ has a unique rooted prefix of length $t$, so it lies in exactly one tube. The first edge of such a prefix has $d$ choices, and every later edge has $d-1$ choices, giving $N_t=d(d-1)^{t-1}$. +\end{proof} + +For a fixed rooted tree-ball $(G,v_0,R)$, after the root has been specified, let $C$ be uniform on $B_R(v_0)$. The probability that $C$ lies in a prescribed length-$t$ tube is +\[ +q_{t,R}:=\Pr(C\in T_\sigma(R)\mid G,v_0,R) +=\frac{|T_\sigma(R)|}{|B_R(v_0)|}. +\] +The partition gives the exact identity +\begin{equation} +\label{eq:tube-mass} +N_tq_{t,R} +=1-\frac{|B_{t-1}(v_0)|}{|B_R(v_0)|}. +\end{equation} +Put $h=R-t$ and $b=d-1$.

Thus $q_{t,R}=\Theta(N_t^{-1})$ uniformly over $R\geq t$, but its leading constant depends on $R-t$ when that difference remains bounded. + +\section{Path-Tube Persistence} + +\subsection{The interception schedule} + +\begin{lemma}[Interception schedule along a tube] +\label{lem:interception} +Let $R\geq t$, suppose $B_R(v_0)$ is a tree-ball, and let +\[ +\sigma=(v_0,v_1,\ldots,v_t) +\] +be a length-$t$ nonbacktracking path starting at $v_0$. Let a cop start at $c\in T_\sigma(R)$ at depth $j=\dist(c,v_0)$. Suppose the robber follows $\sigma$ for as long as the path survives. For every $s\in\{1,\ldots,t\}$ such that the path has survived through round $s-1$, after the cop move in round $s$: +\begin{enumerate}[label=(\roman*)] +\item if $j=2s-1$, the cop reaches $v_{s-1}$ and captures the robber; +\item if $j=2s$, the cop reaches $v_s$ and blocks the intended move; +\item if $j\geq2s+1$, the cop remains a strict descendant of $v_s$. +\end{enumerate} +The alternative $j\leq2s-2$ cannot occur: in that case the path was already captured or blocked by the end of round $s-1$. +\end{lemma} + +\begin{proof} +Set $s_*=\lceil j/2\rceil$. For every reached round $k\leq\min\{s_*,t\}$, an induction shows that before the cop move the cop is a descendant of $v_{k-1}$ and has depth $j-k+1$. This is true at $k=1$. At round $k$, the endpoint-depth sum for the cop and $v_{k-1}$ is $j$, while their rooted-path length is $j-2k+2$. Hence the left side of Lemma~\ref{lem:buffer}'s inequality, with $q=R$, is +\[ +j+(j-2k+2)=2(j-k+1)\leq2j\leq2R. +\] +The rooted path is therefore the unique ambient geodesic, and the cop moves one step toward $v_0$, to depth $j-k$. If $kt$, that time lies beyond the horizon and the cop remains descendant pressure throughout the first $t$ reached rounds. +\end{remark} + +\subsection{Persistence along nonbacktracking paths} + +\begin{theorem}[Nonbacktracking path-tube persistence] +\label{thm:persistence} +Let $d\geq3$ and $1\leq t\leq R$, suppose $B_R(v_0)$ is a tree-ball, and let $X_0$ be any initial cop configuration satisfying +\[ +X_0(T_\sigma(R))\geq1 +\] +for every length-$t$ tube. Cops outside $B_R(v_0)$ are permitted; the proof ignores them unless they cause capture, blockage, or additional branch support. If $X_0(\{v_0\})>0$, the robber is captured before any move. Otherwise, let +\[ +\tau=(v_0,v_1,\ldots,v_t) +\] +be any length-$t$ nonbacktracking path starting at $v_0$. At every round $s\in\{1,\ldots,t\}$ for which the robber has followed $\tau$ through round $s-1$, at least one of the following occurs during round $s$: +\begin{enumerate}[label=(\alph*)] +\item on the cops' move, a cop captures the robber at $v_{s-1}$; +\item after the cops' move, the robber is not captured, but a cop occupies $v_s$, so the intended move is illegal; +\item the move to $v_s$ is legal, and after that move the branch-load support at $v_s$ has size at least $2$. +\end{enumerate} +\end{theorem} + +\begin{proof} +Assume there was no initial capture, and fix a round $s$ reached along $\tau$. If a cop reaches $v_{s-1}$, then (a) holds. If no cop captures the robber but a cop occupies $v_s$, then (b) holds. Assume instead that the move to $v_s$ is legal and produce two branch witnesses. + +\emph{Descendant witness.} +Choose a cop $c^\downarrow$ from $T_\tau(R)$ and let $j_\downarrow$ be its initial depth. Survival through round $s-1$ rules out $j_\downarrow\leq2s-2$, while the failure of alternatives~(a) and~(b) rules out $j_\downarrow\in\{2s-1,2s\}$. Hence $j_\downarrow\geq2s+1$, and Lemma~\ref{lem:interception} implies that after the round-$s$ cop move it is a strict descendant of $v_s$, at depth $j_\downarrow-s$. Its rooted path to $v_s$ has length $j_\downarrow-2s$, so the endpoint-depth sum plus this length is +\[ +(j_\downarrow-s)+s+(j_\downarrow-2s) +=2(j_\downarrow-s)\leq2R. +\] +Lemma~\ref{lem:buffer}, with $q=R$, makes this the unique ambient geodesic. Thus the cop contributes to a child branch of $v_s$. + +\emph{Parent witness.} +Choose $u_0\in N(v_0)\setminus\{v_1\}$, extend $(v_0,u_0)$ to a length-$t$ nonbacktracking path $\sigma'$, and choose a cop $c^\uparrow\in T_{\sigma'}(R)$ of initial depth $j$. Then $R\geq j\geq t\geq s$. We prove by induction on $k\in\{1,\ldots,s\}$ that before its move in round $k$, the cop has depth $j-k+1$ and lies in the root branch through $u_0$. This is immediate for $k=1$. At round $k$, the rooted path from the cop to $v_{k-1}$ passes through $v_0$; both its length and the sum of the endpoint depths equal +\[ +(j-k+1)+(k-1)=j. +\] +Lemma~\ref{lem:buffer}, with $q=R$, therefore forces one step toward $v_0$. If $k0$. If $(m_n)$ is polylogarithmic and $\Pr(\mathcal C_n)\to1$, then $t_n=O(\log\log n)$. If $t_n=\Theta(\log n)$ and $\Pr(\mathcal C_n)\to1$, then +\[ +m_n=\Omega(N_{t_n}\log N_{t_n}), +\qquad +N_{t_n}=d(d-1)^{t_n-1}; +\] +in particular, $m_n\geq n^c$ eventually for some $c>0$. +\end{corollary} + +\begin{proof} +If $t_n\neq O(\log\log n)$, pass to a subsequence on which $t_n/\log\log n\to\infty$, and then to a further subsequence on which $t_n$ is strictly increasing. Apply the proof of Theorem~\ref{thm:sampling-threshold} along this subsequence, with $t$ replaced by $t_n$. Now $t_n\to\infty$ and $N_{t_n}=(\log n)^{\omega(1)}$. Because the threshold is $\Theta(N_{t_n}\log N_{t_n})$ uniformly in $R_n\geq t_n$, polylogarithmic $m_n$ satisfies +\[ +m_n\leq\frac12\frac{\log N_{t_n}}{q_n} +\] +eventually on this subsequence, where $q_n$ is the common tube mass. Part~(ii) of Theorem~\ref{thm:sampling-threshold}, with $\varepsilon=1/2$, then gives $\Pr(\mathcal C_n)\to0$, a contradiction. Hence $t_n=O(\log\log n)$. + +If $t_n=\Theta(\log n)$ and $m_n=o(N_{t_n}\log N_{t_n})$ along a subsequence, pass if necessary to a further subsequence with strictly increasing horizons and apply the same subsequence argument. This contradicts $\Pr(\mathcal C_n)\to1$. Thus $m_n=\Omega(N_{t_n}\log N_{t_n})$. Since $N_{t_n}=n^{\Omega(1)}$, this is at least $n^c$ eventually for some $c>0$. +\end{proof} + +\begin{remark}[Partial coverage is cheaper] +\label{rem:partial-coverage} +At one fixed, known root, the expected fraction of length-$t$ tubes occupied by $m$ independent uniform samples is +\[ +1-(1-q_{t,R})^m. +\] +Since $q_{t,R}=\Theta(N_t^{-1})$, $m=\Theta(N_t)$ samples occupy a fixed positive fraction of the tubes in expectation, while $m=\omega(N_t)$ occupies a $1-o(1)$ fraction in expectation. Under uniform sampling, reducing the expected number of empty tubes to $O(1)$ requires $\Theta(N_t\log N_t)$ samples; the same order is required to leave at most $O(1)$ tubes empty with probability tending to one. These are occupancy statements only: they give neither an adversarial guarantee over all paths from that root nor a root-independent placement, and they do not show that partial coverage supports an adaptive chase. +\end{remark} + +\section{Information Loss in Tube Profiles} +\label{sec:profile-loss} + +Fix integers $Q\geq r\geq1$ and $k\geq0$, and suppose $B_Q(v_0)$ is a tree-ball.

It forgets only how cops at a fixed greater depth split among descendants below the terminal vertex of a length-$r$ prefix. For an admissible profile $P$, define its fixed-universe fiber by +\[ +\mathcal F_{r;Q,k}(P) +:=\{X\in\mathcal C_{Q,k}(v_0):\Pi_{r;Q,k}(X)=P\}. +\] + +\begin{proposition}[Augmented tube profiles do not determine later support] +\label{prop:profile-nondeterminacy} +Fix $d\geq3$ and $r\geq1$, put $Q=2r+3$, and suppose $B_Q(v_0)$ is a tree-ball. There exist $X,Y\in\mathcal C_{Q,2}(v_0)$ and a length-$(r+1)$ nonbacktracking path $\tau=(v_0,\ldots,v_{r+1})$ such that +\[ +\Pi_{r;Q,2}(X)=\Pi_{r;Q,2}(Y). +\] +The path survives all $r+1$ rounds from both configurations, with all relevant cop moves unique, but immediately after the robber's legal move to $v_{r+1}$ the branch-load supports in $X$ and $Y$ have sizes $2$ and $1$, respectively. Hence, for this fixed path $\tau$, the predicate that the branch-load support after $r+1$ safe rounds has size at least $2$ does not factor through $\Pi_{r;Q,2}$. +\end{proposition} + +\begin{proof} +Choose $\tau$ and two distinct children $a,b$ of $v_{r+1}$. Choose descendants $x_a$ of $a$ and $x_b$ of $b$ at total depth $Q=2r+3$ from $v_0$, and choose two distinct descendants $y_a,y_a'$ of $a$ at the same total depth. Such choices exist because the vertices at descendant-distance $r+1$ below $a$ number $(d-1)^{r+1}\geq2$. Define +\[ +X=[x_a,x_b], +\qquad +Y=[y_a,y_a']. +\] +Both configurations have zero multiplicity on $B_{r-1}(v_0)$, and their only nonzero tube-depth coordinate is the cell indexed by $((v_0,\ldots,v_r),Q)$, where both have value $2$. Thus their augmented profiles agree. + +Every robber position on $\tau$ is an ancestor of every cop in the construction. Immediately before the cop move in round $s$, each cop has total depth $Q-s+1$, while the robber is at $v_{s-1}$. Their rooted path has length $Q-2s+2$, and +\[ +(Q-s+1)+(s-1)+(Q-2s+2)=2Q-2s+2\leq2Q. +\] +Lemma~\ref{lem:buffer}, with $q=Q$, therefore makes this path the unique ambient geodesic and forces one step upward.

After $r+1$ cop moves, the configurations are $[a,b]$ and $[a,a]$, so the branch-load support sizes after the robber moves to $v_{r+1}$ are $2$ and $1$. +\end{proof} + +For $r=1$, the profile includes the multiplicity at $v_0$ as well as the depth histogram in every first-level tube, yet it still does not determine the two-round outcome.

The larger radius $R+t$ is sharp, among possibly infinite $d$-regular graphs, for uniform control of arbitrary endpoint pairs, but the synchronized chase witnesses require only $B_R(v_0)$. The length-$t$ tubes partition the outer ball into $N_t=d(d-1)^{t-1}$ parts, and occupying every tube gives the stated capture, blockage, or two-branch-support alternative along every prescribed path in this class. + +At one fixed root the deterministic occupancy cost is $N_t$.

For graphs of maximum degree $d$, one selected vertex can cover at most +\[ + B_h=1+d\frac{(d-1)^h-1}{d-2} +\] +vertices, so the elementary volume bound is $\gamma_h(G)\ge n/B_h$. In ideal tree-ball geometry, independent selection and patching place the natural covering scale at $n\log B_h/B_h$. + +The first-moment balance is subtler than the leading scale. If $\alpha=C/B_h$, subset entropy is approximately +$C(\log B_h-\log C+1)/B_h$, while the probability that a tree ball is missed is approximately $e^{-C}$. Equating these terms predicts +\[ + C=\log B_h-2\log\log B_h+O(1). +\] +The present paper determines that bounded annealed window and its entire limiting profile. With $L_h=\log B_h$, uniformly for bounded $s$, +\[ + \frac{B_h}{L_h^2} + \Psi_{d,h}\!\left( + \frac{L_h-2\log L_h+s}{B_h} + \right) + \longrightarrow 1-e^{-s}. +\] +Thus the annealed exponent changes sign at $s=0$, and its lower zero is governed, to power accuracy in $B_h$, by the scalar equation +\[ + H(C/B_h)=(1-C/B_h)^{B_h}. +\] +This gives not only the first two terms but the complete fixed-order inverse-logarithmic expansion of the annealed transition. + +For the random graph itself, the first moment yields a fixed-slack lower theorem: for every fixed $\omega>0$, subject to +\[ + \frac{n(\log B_h)^2}{B_h}\gg h\log n, +\] +one has with high probability +\[ + \gamma_h(G_{n,d})\ge + \frac n{B_h} + \bigl(\log B_h-2\log\log B_h-\omega\bigr). +\] +At the comparison scale $B_h\asymp\sqrt n$, this is +\[ + \gamma_h(G_{n,d})\ge + \frac n{B_h} + \bigl(\tfrac12\log n-2\log\log n-\omega+O(1)\bigr) + =\Omega(\sqrt n\log n). +\] +This is an annealed lower transition, not a quenched matching theorem. Proving the existence of dominating sets at the same coordinate remains separate. + +The comparison scale is also relevant to pursuit-evasion: Meyniel's conjecture predicts that $O(\sqrt n)$ cops suffice in every connected $n$-vertex graph~\cite{LuPeng2012,ScottSudakov2011}, and it is known for several random-graph models, including random regular graphs~\cite{PralatWormald2016,PralatWormald2019}. Our conclusion is not a cop-number lower bound. It says that one particular static exhaustive coverage mechanism can require a logarithmic factor more than the Meyniel scale. + +\subsection{Why the first moment is difficult} +For an independent random subset of density $\alpha$, a fixed tree-like radius-$h$ ball is missed with probability approximately $(1-\alpha)^{B_h}$. Balancing subset entropy against this coupon term predicts the coordinate +\[ + \alpha B_h\approx \log B_h-2\log\log B_h. +\] +Turning that heuristic into a theorem is not a product-measure calculation. In the configuration model, coverage events for different vertices overlap heavily, and optimizing over the selected set allows highly organized profiles. A direct bounded-differences argument is also ineffective in the growing-radius regime: changing one pairing can alter the radius-$h$ coverage status of order $B_h$ vertices, so the natural Lipschitz constant grows on exactly the scale that must be resolved. + +The key device is to label every vertex by its \emph{exact} distance to the candidate set. Local consistency of these labels---adjacent labels differ by at most one, and every positive label has a neighbor one level lower---forces them to be genuine graph distances on any graph. This removes the need to approximate neighborhoods by trees and converts the first moment into an exact finite-dimensional method-of-types problem. The price is a nonconcave variational functional whose global optimizer must be identified uniformly as the number of distance levels grows. + +\subsection{Related work} +The configuration or pairing model and its transfer to uniformly random simple regular graphs are standard; see Wormald's survey~\cite{Wormald1999} and Janson's simplicity theorem~\cite{Janson2009}. Fixed-radius domination in random regular graphs has been studied algorithmically: Duckworth analyzed randomized greedy algorithms for distance-$k$ dominating sets~\cite{Duckworth2005}, while Duckworth and Wormald treated independent domination~\cite{DuckworthWormald2006}. The broader covering viewpoint is classical in coding theory~\cite{CohenHonkalaLitsynLobstein1997}. + +The closest message-passing antecedents are statistical-mechanical. Zhao, Habibulla, and Zhou developed a cavity-method and belief-propagation treatment of minimum dominating sets~\cite{ZhaoHabibullaZhou2015}; Habibulla and Qin studied a distance-two version with distance-labeled messages~\cite{HabibullaQin2019}. Those works are replica-symmetric and fixed-radius. The transfer equations below are closely related in spirit; the distinctions here are the exact graph-level type count, the proof of global optimization, and the growing-radius asymptotics. + +Cutler and Radcliffe used Shearer entropy to obtain universal extremal bounds for domination polynomials of regular graphs~\cite{CutlerRadcliffe2016}. Such universal bounds cannot by themselves detect the random-covering penalty: structured regular graphs may admit efficient covering codes. In the binomial random graph, Glebov, Liebenau, and Szab\'o proved two-point concentration at the first-moment threshold in a sufficiently dense regime~\cite{GlebovLiebenauSzabo2015}. That result motivates, but does not supply, the corresponding quenched statement for random regular graphs. + +The pursuit application comes from branch-based local coverage. Aigner and Fromme introduced the multiple-cop game in its modern graph-theoretic form~\cite{AignerFromme1984}; Pra\l at and Wormald later combined random placement with deterministic pursuit in random graphs~\cite{PralatWormald2016,PralatWormald2019}. The local tube certificate in~\cite[Theorem~3.3 and Section~6.4]{Neuwirth2026Tube} motivates a root-independent two-witness covering problem. Section~\ref{subsec:tube-connection} states the exact graph-general parameter used here and carefully limits the resulting obstruction. + +\subsection{Proof architecture and contributions} +The proof has four acts. + +\paragraph{Act I: exact types and a compact functional.} +Exact distance labels produce a two-sided type estimate +\[ + \log \E N_{\mathbf n} + =n\Phi_{d,h}(\mathbf n/n)+O_d(h\log n). +\] +Optimizing the local profile entropy at fixed tridiagonal edge masses reduces $\Phi_{d,h}$ exactly to a compact functional $\Fcal_{d,h}$ in $2h+1$ variables. The lower side of the type estimate also yields the pointwise entropy anchor +$\Psi_{d,h}(\alpha)\le H(\alpha)$. + +\paragraph{Act II: globality without concavity.} +The compact functional is genuinely nonconcave. Nevertheless, entropy singularities repel every maximizing profile from the boundary. Interior KKT points are equivalent to positive message solutions. An exact reverse transfer reconstructs every positive stationary solution from one terminal parameter, and the associated activity is strictly increasing from $0$ to $\infty$. Hence the grand-canonical optimizer is unique at every activity, and duality gives +\[ + \Psi_{d,h}(\alpha)=\Psi^{\mathrm{stat}}_{d,h}(\alpha), + \qquad + \Psi_{d,h}'(\alpha)=-\log z(\alpha). +\] + +\paragraph{Act III: quantitative orbit matching.} +The reverse orbit has exact stable and free outer solutions. They overlap over linearly many levels. Retaining the actual transverse errors gives, for +$c=\alpha B_h/\log B_h<4/3$, +\[ + -\log z(\alpha)-\log\frac1\alpha + =B_h(1-\alpha)^{B_h} + \left(1+B_h^{-c/4+o(1)}\right) + +B_h^{-c/4+o(1)}. +\] +The restriction $c<4/3$ is exactly where the additive reconstruction error remains smaller than the coupon term. + +\paragraph{Act IV: one terminal conditioning cost.} +An explicit capped-free profile agrees with the free Bernoulli tree law at every nonterminal layer. Its only entropy loss comes from conditioning the terminal lower-neighbor set to be nonempty. That loss is exactly +\[ + p_h\Delta_d(\varepsilon_h), + \qquad + p_h\varepsilon_h^d=(1-\alpha)^{B_h}, + \qquad + \Delta_d(\varepsilon)=\varepsilon^d(1+o(1)). +\] +This supplies the sharp upper bound on $H-\Psi$. Integrating the quantitative activity law supplies the matching lower bound and the universal scaling function $1-e^{-s}$. + +The principal contributions are therefore: an exact growing-radius type count with no local-tree assumption; an exact compact reduction; a global solution of a nonconcave annealed variational problem; quantitative stable/free matching; and a bounded-window theorem anchored by a self-contained feasible profile. Quenched matching and direct two-branch asymptotics remain separate problems. + +\section{Models, notation, and main results}\label{sec:main} +Fix $d\ge3$ throughout and put +\[ + b=d-1,\qquad D=\frac{b+1}{b-1}=\frac d{d-2}, +\] +\begin{equation}\label{eq:Bh} + B_h=1+d\frac{b^h-1}{b-1}=Db^h-\frac2{b-1}. +\end{equation} +For a probability vector $r=(r_1,\ldots,r_k)$, write +\[ + H(r)=-\sum_{j=1}^k r_j\log r_j, +\] +with $0\log0=0$; for a scalar $a\in[0,1]$, $H(a)$ denotes the binary entropy $H(a,1-a)$. + +\begin{center} +\begin{tabular}{ll} +\toprule +Notation & Meaning\\ +\midrule +$B_h$ & maximum radius-$h$ ball volume at degree $d$\\ +$\gamma_h(G)$ & minimum size of a distance-$h$ dominating set\\ +$\Phi_{d,h}$ & full local-profile type functional\\ +$\Fcal_{d,h}$ & compact tridiagonal profile functional\\ +$\Psi_{d,h}(\alpha)$ & microcanonical annealed exponent at density $\alpha$\\ +$z=e^\theta$ & grand-canonical activity\\ +$b=d-1$, $D=d/(d-2)$ & recurring degree constants\\ +\bottomrule +\end{tabular} +\end{center} + +\begin{definition}[Internally two-path $(h,2)$ domination]\label{def:two-path} +A set $S\subseteq V(G)$ is \emph{internally two-path $(h,2)$ dominating} if every vertex $v\notin S$ has two $v$--$S$ paths of length at most $h$ whose only common vertex is $v$. In particular, the paths begin through distinct neighbors of $v$. Let $\gamma_{h,2}^{\mathrm{int}}(G)$ denote the minimum size of such a set. +\end{definition} + +Every internally two-path $(h,2)$-dominating set is distance-$h$ dominating, since either witness path alone ends in $S$ within distance $h$. Therefore +\begin{equation}\label{eq:two-path-dominates} + \gamma_{h,2}^{\mathrm{int}}(G)\ge \gamma_h(G). +\end{equation} + +\subsection{Connection with static tube coverage}\label{subsec:tube-connection} +In the tree-ball setting of~\cite{Neuwirth2026Tube}, a length-$t$ tube with residual depth $h=R-t$ depends, after the root is allowed to vary, only on its terminal directed edge. The resulting forward cone excludes one branch at its head. A root-independent set meets every such directed cone exactly when, at every unselected vertex, at least two distinct branches contain a selected vertex within distance $h$; in a tree-ball these are precisely the two internally disjoint paths of Definition~\ref{def:two-path}. Thus internally two-path domination is a graph-general strengthening of the global exhaustive tube certificate. + +Combining~\eqref{eq:two-path-dominates} with the main theorem shows that any such exhaustive static certificate has size $\Omega(\sqrt n\log n)$ at the comparison scale $B_h\asymp\sqrt n$. Meyniel's conjecture concerns the existence of a fully adaptive winning strategy with $O(\sqrt n)$ cops, so there is no contradiction: the lower bound applies only to this static exhaustive mechanism. Partial coverage, adaptive reassignment, and epoch-based pursuit remain outside the argument. + +The pairing model consists of $n$ labeled buckets of $d$ half-edges paired uniformly at random; conditioning the resulting multigraph on simplicity gives the uniformly random simple $d$-regular graph $G_{n,d}$, for $dn$ even. Let $Z_{n,d,h}(m)$ count distance-$h$ dominating $m$-sets in the pairing model. + +For a distance-$h$ dominating set $S$, assign each vertex its exact label $\operatorname{dist}(v,S)\in\{0,\ldots,h\}$. The local consistency used below is equivalent to genuine distance: adjacent labels differ by at most one, and every positive label has a neighbor one level lower. The descending condition gives a path to label zero of the displayed length, while the Lipschitz condition gives the reverse inequality. No tree-neighborhood assumption is involved. + +The type count developed below gives +\begin{equation}\label{eq:type-count-intro} + \log\E Z_{n,d,h}(m) + \le n\Psi_{d,h}(m/n)+O_d(h\log(n+1)), +\end{equation} +uniformly in $h$.

Conditional on label $i\ge1$, the set of lower-label half-edges has the entropy-maximizing tilted nonempty-subset law with coordinate marginal $a_i$; conditional on that set, every remaining half-edge independently receives label $i$ or $i+1$ with probabilities $\ell_i/y_i$ and $x_{i+1}/y_i$. +\end{lemma} + +\begin{proof} +First expose the central label. Its entropy is $H(p_0,\ldots,p_h)$. Conditional on the central label $i$, choosing a local count vector and then assigning the $d$ labeled half-edges contributes exactly the entropy of the induced law on words of length $d$ over the allowed neighboring labels. + +For $i=0$, only labels $0$ and $1$ are allowed and their coordinate marginals are $\ell_0/p_0$ and $x_1/p_0$. Subadditivity of entropy is sharp only for independent coordinates, giving the first term of~\eqref{eq:local-reduction}. + +Fix $i\ge1$. Mark the coordinates whose neighbor label is $i-1$. Their random subset is nonempty and has common coordinate marginal +\[ + a_i=\frac{q_{i,i-1}}{p_i}=\frac{x_i}{p_i}. +\] +By definition, its entropy is at most $s_d(a_i)$, with equality for the exponential tilt +\[ + \Pr(A)\propto \lambda^{|A|},\qquad \varnothing\ne A\subseteq[d], +\] +where $\lambda$ satisfies~\eqref{eq:sd-marginal}; this also proves the dual formula~\eqref{eq:sd}.

The root contribution at $i=1$ has the same algebra, with the activity term cancelling through the root diagonal equation. +\end{proof} + +\begin{proposition}[Compact KKT equals two-message stationarity]\label{prop:kkt-message} +Every strict interior KKT point determines positive messages satisfying~\eqref{eq:msg-root}--\eqref{eq:msg-B}. Conversely, every positive message solution reconstructs a strict interior KKT point by +\[ + q_{ii}=\frac{B_i^2}{Z_e}, + \qquad + q_{i-1,i}=\frac{B_{i-1}A_i}{Z_e}. +\] +\end{proposition} + +\begin{proof} +Put +\[ + T_i=B_i+A_{i+1}, + \qquad + S_i=B_{i-1}+T_i. +\] +By Lemma~\ref{lem:kkt-lambda}, $\lambda_i=B_{i-1}/T_i$. Exponentiating the diagonal KKT equation and using~\eqref{eq:sd-identities} shows that one common constant $\kappa>0$ satisfies +\[ + \kappa + =\frac{((1+\lambda_i)^d-1)y_i^d}{p_iB_i^d} + =\frac{S_i^d-T_i^d}{p_i} +\] +for every $i\ge1$. Hence +\[ + p_i=\frac{S_i^d-T_i^d}{\kappa}. +\] +The descent marginal formula gives +\[ + x_i=a_ip_i + =\frac{B_{i-1}S_i^b}{\kappa}. +\] +Since $x_i=B_{i-1}A_i$, this is~\eqref{eq:msg-A}. Subtracting $x_i$ from $p_i$ gives +\[ + y_i=\frac{T_i(S_i^b-T_i^b)}{\kappa}. +\] +Since $y_i=B_iT_i$, this is~\eqref{eq:msg-B}. At the root, the diagonal KKT equation gives +\[ + \kappa=\frac{zp_0^b}{B_0^d}. +\] +Because $p_0=B_0(B_0+A_1)=B_0S_0$, this is~\eqref{eq:msg-root}. + +Conversely, let positive messages satisfy the stationarity equations. Put $\sigma=Z_e^{-1/2}$ and introduce normalized messages +\[ + \widehat A_i=\sigma A_i, + \qquad + \widehat B_i=\sigma B_i, + \qquad + \widehat\kappa=\sigma^{b-1}\kappa. +\] +Then +\[ + \widehat\kappa\widehat A_i=\widehat S_i^b, + \qquad + \widehat\kappa\widehat B_i + =\widehat S_i^b-(\widehat S_i-\widehat B_{i-1})^b, + \qquad + \widehat\kappa\widehat B_0=z\widehat S_0^b. +\] +The reconstructed beliefs are simply +\[ + \ell_i=\widehat B_i^2, + \qquad + x_i=\widehat B_{i-1}\widehat A_i. +\] +They have total mass one by the definition of $Z_e$. Writing +\[ + \widehat T_i=\widehat B_i+\widehat A_{i+1}, + \qquad + \lambda_i=\frac{\widehat B_{i-1}}{\widehat T_i}, +\] +the message equations give the exact row identities +\[ + p_i=\frac{\widehat S_i^d-\widehat T_i^d}{\widehat\kappa}, + \qquad + x_i=\frac{\widehat B_{i-1}\widehat S_i^b}{\widehat\kappa}, + \qquad + y_i=\frac{\widehat T_i(\widehat S_i^b-\widehat T_i^b)}{\widehat\kappa}. +\] +Consequently $a_i=x_i/p_i$ is exactly the tilted conditioned-binomial marginal with parameter $\lambda_i$, and +\[ + \lambda_i y_i + =\widehat B_{i-1}\widehat B_i + =\sqrt{\ell_{i-1}\ell_i}. +\] +Substitution into the diagonal derivative gives, for every $i\ge1$, +\[ + g_i=\log\widehat\kappa+\frac{d-2}{2}. +\] +The root equation gives the same value for $g_0$. Finally, the displayed edge identity and $s_d'(a_i)=-d\log\lambda_i$ make the difference between the $x_i$ derivative and $g_{i-1}+g_i$ vanish exactly. Thus, with +\[ + \mu=\log\widehat\kappa+\frac{d-2}{2}, +\] +one has +\[ + \frac{\partial\Fcal^{(z)}}{\partial\ell_i}=\mu, + \qquad + \frac{\partial\Fcal^{(z)}}{\partial x_i}=2\mu, +\] +which is~\eqref{eq:kkt-weight}. Positivity makes the point strict interior, and common message scaling cancels from the beliefs. +\end{proof} + + + +\subsection{One-dimensional positive stationary locus} +The equations are homogeneous: common message scaling changes $\kappa$ but not $z$ or the reconstructed profile. In the gauge $\kappa=1$, choosing $B_h>0$ determines all preceding messages uniquely by +\begin{equation}\label{eq:message-backward} + A_i=B_i+(B_i+A_{i+1})^b, + \qquad + B_{i-1}=A_i^{1/b}-B_i-A_{i+1}, +\end{equation} +for $i=h,h-1,\ldots,1$. Positivity is automatic because +\[ + B_{i-1}=\left((B_i+A_{i+1})^b+B_i\right)^{1/b}-(B_i+A_{i+1})>0. +\] +Thus the positive stationary locus is one dimensional before the activity is imposed. + + +\section{Exact reverse transfer and monotone activity shooting} +Normalize $A_1=1$ and put +\[ + \rho_i=\frac{B_i}{A_i}, + \qquad + u_i=\frac{A_{i+1}}{A_i}, + \qquad + v_i=\rho_i+u_i. +\] +At the terminal level, $u_h=0$, so +\[ + \rho_h=v_h=:s\in(0,1). +\] +Let +\[ + \Dcal=\{(\rho,v):0<\rho\le v\le1\}. +\] + +\begin{proposition}[Exact reverse map]\label{prop:reverse-map} +Given a next-level state $(\rho',v')\in\Dcal$, define +\[ + w=(1-\rho')^{1/b}, + \qquad + e=1-w, +\] +\[ + R=v'\frac ew, + \qquad + M=\left(e+\frac w{v'}\right)^b. +\] +Then its unique positive predecessor is +\begin{equation}\label{eq:reverse-map} + \boxed{ + \rho=\frac{R}{R+M}, + \qquad + v=\frac{1+R}{R+M}. + } +\end{equation} +The remaining coordinates are +\begin{equation}\label{eq:reverse-out} + u=\frac1{R+M},\qquad q=\frac{M-1}{R+M}. +\end{equation} +The map sends $\Dcal$ into itself. +\end{proposition} + +\begin{proof} +The forward transfer identities imply +\[ + \frac\rho u=v'\frac ew=R. +\] +The next lower-neighbor fraction also gives +\[ + e=\frac{\rho(1-\rho)^{1/b}} + {u^{1/b}(u+\rho)}. +\] +Substituting $\rho=Ru$ and solving yields +\[ + u=\frac1{R+M}, +\] +which gives~\eqref{eq:reverse-map}. Uniqueness follows from the algebraic solution.

The reverse map is continuous at every interior state and has the displayed boundary limit; induction over the fixed number $h-1$ of reverse steps therefore sends every earlier state to $(0,0)$. Equation~\eqref{eq:z-root-reverse} then gives $z\to0$. + +As $s\uparrow1$, one has $w\to0$, $R\to\infty$, and $M\to1$, so one reverse step tends to $(1,1)$. The same finite-step induction sends every earlier state to $(1,1)$. Hence $m\to\infty$, $v_1\to1$, and~\eqref{eq:z-root-reverse} gives $z\to\infty$. Continuity of the reverse map and of~\eqref{eq:z-root-reverse} also makes $s\mapsto z_h(s)$ continuous. +\end{proof} + +\begin{theorem}[Unique positive stationary point]\label{thm:unique-stationary} +For every $d\ge3$, $h\ge1$, and $z>0$, the exact grand-canonical stationarity equations have exactly one positive solution up to common message scaling. +\end{theorem} + +\begin{proof} +Every positive solution has one terminal parameter $s=\rho_h\in(0,1)$ and is uniquely reconstructed by Proposition~\ref{prop:reverse-map}.

Theorem~\ref{thm:full-interiority} places every maximizer in the strict interior, so every maximizer satisfies the interior stationarity equations. Theorem~\ref{thm:unique-stationary} gives only one such point. +\end{proof} + +The microcanonical problem follows by duality. + +\begin{theorem}[Microcanonical globality]\label{thm:micro-globality} +For every density +\[ + \frac1{B_h}<\alpha<1, +\] +the exact microcanonical functional has a unique global maximizer, and it is the positive stationary profile on the reverse-transfer branch with selected density $\alpha$. Equivalently, +\[ + \boxed{ + \Psi_{d,h}(\alpha)=\Psi^{\mathrm{stat}}_{d,h}(\alpha) + } +\] +throughout the interior feasible interval. +\end{theorem} + +\begin{proof} +Write $\theta=\log z$ and +\[ + \phi_{d,h}(\theta) + =\max_{(x,\ell)\in\Pcal_{d,h}} + \{\Fcal_{d,h}(x,\ell)+\theta p_0\}. +\] +By Theorem~\ref{thm:grand-globality}, the maximizer is unique for every $\theta$. Danskin's theorem~\cite{RockafellarWets1998} therefore gives +\[ + \phi_{d,h}'(\theta)=\alpha(\theta), +\] +the density of that maximizer. The derivative of a differentiable convex function is continuous here (equivalently, one may use continuity of the unique optimizer). It is also strictly increasing. Indeed, if $\theta_1<\theta_2$ had the same maximizing density, the two optimality inequalities would force each optimizer to maximize at both activities. Grand-canonical uniqueness would make the profiles equal, but the root equation assigns one activity to an interior stationary profile, a contradiction. To identify the endpoint limits, let $\theta_k\to-\infty$ and pass, by compactness, to a convergent subsequence of optimizers. Comparing with a feasible profile of density $1/B_h$ shows that any limit must minimize $p_0$ over the polytope, hence has density $1/B_h$. Similarly, along $\theta_k\to\infty$, comparison with the all-selected profile forces every subsequential limit to have density $1$. Therefore +\[ + \alpha(\theta)\longrightarrow\frac1{B_h} + \quad(\theta\to-\infty), + \qquad + \alpha(\theta)\longrightarrow1 + \quad(\theta\to\infty). +\] +Hence every interior density is attained. + +Fix $\alpha$ and choose $\theta$ with $\alpha(\theta)=\alpha$. For every profile $P$ of density $\alpha$, +\[ + \Fcal(P)+\theta\alpha + \le + \Fcal(P_\theta)+\theta\alpha, +\] +so $P_\theta$ is the microcanonical maximizer. Uniqueness follows from grand-canonical uniqueness. +\end{proof} + +\begin{corollary}[Concavity and the envelope identity]\label{cor:envelope} +The exact value function $\Psi_{d,h}$ is strictly concave on $(1/B_h,1)$ and differentiable there.

The consolidated solver evaluates these differences as +\[ + S_i^d\bigl[-\operatorname{expm1}(d\log(1-B_{i-1}/S_i))\bigr] +\] +and reports the microcanonical exponent through the corrected root-only formula~\eqref{eq:root-micro-correct}. The direct partition-function route is retained as an independent comparison. A row is rejected unless +\[ + \frac{|\Psi_{Z_v}-\Psi_{\rm root}|}{|\Psi_{\rm root}|}\le10^{-6}. +\] +Thus a cross-check residual comparable to the reported quantity gates the record rather than remaining hidden in an internal data structure. + +For the diagnostic choice $W_h=\log\log B_h$, the regenerated cubic values are +\begin{center} +\begin{tabular}{cccc} +\toprule +$h$ & $C$ & $-\Psi/e^{-C}$ & activity-law ratio\\ +\midrule +20 & $6.8451$ & $0.6484$ & $0.5873$\\ +30 & $12.6345$ & $0.9418$ & $0.9520$\\ +40 & $18.7408$ & $0.9757$ & $0.9956$\\ +52 & $26.2980$ & $0.9819$ & $0.9997$\\ +\bottomrule +\end{tabular} +\end{center} +The activity-law ratio is +\[ + \frac{-\log z-\log(1/\alpha)}{B_h(1-\alpha)^{B_h}}. +\] +The effective onset is slower when $C/\log B_h$ is small, consistent with uniformity only on compact intervals bounded away from zero. Every numerical row records the checker hash, solver hash, precision, stationarity residual, telescoping residual, and the discrepancy between the direct and root-only free-energy routes. + + + + +The bounded-window audit evaluates both the true stationary optimizer and the capped-free profile at the center $s=0$. The two quantities approach the coupon term from opposite sides: +\begin{center} +\begin{tabular}{cccc} +\toprule +$(d,h)$ & $(H-\Psi)/Q_h$ & cap loss$/Q_h$ & $C_h^{\rm ann}-\widehat C_{B_h}$\\ +\midrule +$(3,20)$ & $0.8750056$ & $1.0593258$ & $-1.03077\times10^{-1}$\\ +$(3,30)$ & $0.9902396$ & $1.0076650$ & $-8.00386\times10^{-3}$\\ +$(3,40)$ & $0.9990005$ & $1.0009330$ & $-8.57353\times10^{-4}$\\ +$(4,24)$ & $0.9999148$ & $1.0000702$ & $-6.78418\times10^{-5}$\\ +$(4,32)$ & $0.9999988$ & $1.0000012$ & $-1.01763\times10^{-6}$\\ +\bottomrule +\end{tabular} +\end{center} +The cap-loss and product identities are evaluated independently from the compact functional; their recorded residuals are below $10^{-120}$ in the displayed high-precision runs. The stationary entropy-defect identity~\eqref{eq:defect-identity} and the graph-zero computations provide separate checks of the two sides of the proof. + +\section{Consequences and open problems}\label{sec:open} +Theorems~\ref{thm:bounded-critical-window} and~\ref{thm:random-fixed-window} determine the annealed transition, its bounded window, and its universal scaling function. The capped-free construction also isolates the mechanism behind the coupon term: at the critical scale, the leading entropy defect is the cost of forbidding one empty terminal branch set. Two harder frontiers remain logically separate. + +\paragraph{Quenched matching.} +The random-regular theorem is a first-moment lower bound. A matching upper bound near $C_h^{\rm ann}$ would require proving that dominating sets actually exist above the annealed crossing. Plausible routes include a second-moment analysis with an overlap variational problem, small-subgraph conditioning, or an algorithmic construction whose output reaches the scalar coupon coordinate. The bounded-window theorem now supplies a precise target and separates any quenched correction from uncertainty in the annealed calculation. + +\paragraph{Direct two-branch asymptotics.} +Internally two-path $(h,2)$ domination is stronger than ordinary distance domination, so the present lower bound transfers automatically. It does not identify the parameter's own leading constant or critical correction. A direct treatment must remember branch information without falsely treating two paths that later merge as internally disjoint. Directed nonbacktracking cavity states are a natural exact intermediary, but the corresponding type system and variational reduction remain to be developed. + +The exponent $1/7$ in the graph--scalar comparison is a bookkeeping exponent rather than a predicted optimum. Improving it would sharpen finite-$h$ convergence but would not change the scaling function or any fixed-order inverse-logarithmic term. + +\section*{Acknowledgements} +\emph{To be completed by the author before circulation.} + +\begin{thebibliography}{99} +\bibitem{AignerFromme1984} +M.

+   On wide viewports (≥ 1500px) the sidenote  is positioned

+   We do NOT use float because float with negative margin is unreliable

+
+   position: absolute with no explicit top/bottom uses the "hypothetical
+   static position" — the spot the element would occupy if position: static.
+   For an inline  inside a 
      , this is roughly the line containing
+   the sidenote reference, giving correct vertical alignment without JS.
+
+   On narrow viewports the  is hidden and the
+   
       the Sidenotes filter appends at document

+/* vita.css — /about.html and /cv/projects/.
+ *
+ * The vita is a record surface. Where Now answers "what is moving right
+ * now" with a status chip per item, the vita answers "what is on file" and
+ * carries no temporality beyond the dates themselves — so it borrows
+ * item-card.css's card rhythm and now.css's section headings, but drops the
+ * badge column entirely. Entries here have no state to report.
+ *
+ * SPECIFICITY NOTE. Almost every selector below is prefixed with
+ * #markdownBody, and that is load-bearing rather than habit. typography.css
+ * styles the prose surface through #markdownBody (1,0,1) — including
+ * `:is(h1..h6)` at display sizes with 2.475rem margins, and a 1.5em
+ * text-indent on `p + p` for essay prose. A bare `.vita-entry-title` (0,1,0)
+ * loses to those no matter what order the stylesheets load in, which is
+ * exactly what went wrong the first time: entry titles rendered at 1.45rem
+ * sans with heading margins, and every second paragraph in a card sat
+ * indented like a continuation of running prose.
+ *
+ * Now sidesteps this by never using heading elements inside its cards. The
+ * vita keeps them — a record page wants a real document outline for anyone
+ * navigating by heading — and pays for them with specificity instead.

+/* work.css — /work.html, the professional front door.
+ *
+ * This page has a different job from every other surface on the site. Vita
+ * and the project index are RECORD pages: generated from the CV data, complete,
+ * and unranked. Work is an ARGUMENT page — hand-written, deliberately partial,
+ * and ordered. Four entries carry it, and a reader must be able to tell within
+ * a screen what the claim is and where the evidence lives.
+ *
+ * SPECIFICITY NOTE. Every selector below is prefixed with #markdownBody for the
+ * same reason vita.css does it: typography.css owns the prose surface through
+ * #markdownBody (1,0,1), including :is(h1..h6) at display sizes and the 1.5em
+ * text-indent on `p + p` that essay prose relies on. A bare .work-entry (0,1,0)
+ * loses to that regardless of load order — entry headings would render at essay
+ * scale and every second paragraph inside a card would sit indented like
+ * running prose. The prefix is load-bearing, not habit.

+/* Photography section — view mode toggle and masonry row-span computation.
+ *
+ * Mode toggle:
+ *   - Three modes: masonry (default), grid, chronological.
+ *   - Selection persists to localStorage under "photography-mode".
+ *   - Mode is applied as data-photography-mode on .photography-grid;
+ *     CSS keys all per-mode rules off this attribute.
+ *
+ * Masonry row-spans:
+ *   - In masonry mode, .photography-grid uses CSS grid with
+ *     grid-auto-rows: 1px so each card can occupy a precise integer
+ *     number of "row units" matching its image's natural aspect.
+ *   - For each photo card we set inline grid-row: span N once the
+ *     image's natural dimensions are known. Pre-load, the card uses
+ *     orientation-derived defaults from data-orientation so initial
+ *     paint is roughly the right shape.
+ *
+ * No-op gracefully:
+ *   - If the page has no .photography-grid (i.e. we're not on the
+ *     /photography/ landing) the script returns early.
+ *   - If localStorage is unavailable, mode toggling still works for
+ *     the duration of the visit; just no persistence.

+ *   /data/semantic-meta.json   [{url, title, heading, excerpt}, ...]

+ * Model: Xenova/all-MiniLM-L6-v2 (~22 MB quantized, cached by browser after first load)
+ * Model files served from /models/all-MiniLM-L6-v2/ (same-origin; run tools/download-model.sh)
+ * Index format: raw little-endian Float32, shape [N, 384], unit-normalized

+ *   <span class="sidenote" id="sn-N">…</span>
+ *
+ * #markdownBody must be position: relative (layout.css guarantees this).

+ * Without an explicit top they sit at their "hypothetical static position",
+ * which is fine for isolated notes but causes overlaps when notes are close.
+ *
+ * This script:
+ *   1. Anchors each sidenote's top to its reference's offsetTop so the
+ *      alignment is explicit and stable across all browsers.
+ *   2. Walks notes top-to-bottom and pushes each one below the previous
+ *      if they would overlap (with a small gap between them).
+ *   3. Wires bidirectional hover highlights between each ref↔sidenote pair.

+"""Reader-facing computations for growing-radius domination.
+
+This script accompanies the essay version of the preprint
+
+    Near-Critical First-Moment Lower Bounds for
+    Growing-Radius Domination in Random Regular Graphs.
+
+It deliberately keeps the mathematical structure visible.  The core steps are:
+
+1. compute the tree-ball volume B_h;
+2. evaluate the conditioned local entropy s_d(a);
+3. evaluate the exact compact microcanonical functional;
+4. solve the unique stationary orbit by reverse transfer;
+5. reconstruct density, activity, and free energy at the root;
+6. target the near-critical coordinate C = alpha B_h;
+7. gate every reported row by independent residual checks.
+
+Only ``mpmath`` is required for the main calculations.  ``matplotlib`` is
+optional and is used only by ``--plot``.
+
+The code is expository, not optimized for maximum throughput.  Numerical
+calculations illustrate the theorem and audit the identities; they are not
+used in its proof.

+# add-popup-source.sh — Scaffold a new popup provider end-to-end.
+#
+# Prompts for the handful of facts unique to a new source (name, label,
+# a sample URL), then:
+#   1. Probes the upstream for CORS support and content-type.
+#   2. Prints a PROVIDERS entry stub you paste into static/js/popups.js.
+#   3. If CORS-broken, prints + (on confirmation) appends an nginx
+#      location block to nginx/popup-proxy.conf.
+#   4. Prints a remaining-steps checklist (icon SVG, CSS, CSP comment).
+#
+# The parse() body is left as a TODO — writing it requires eyes on the
+# actual API response, which this tool also fetches and pretty-prints so
+# you can inspect the response shape without a second terminal.
+#
+# Never writes to static/js/popups.js automatically — that file has too
+# much surrounding structure to edit blindly. Copy-paste is safer.

+Hakyll input data/archive-index.json.
+
+Two artifact types:
+  * pdf  — downloaded directly, stored as document.pdf, text via pdftotext.
+  * html — snapshotted with `monolith` into a single self-contained
+           snapshot.html (JavaScript stripped, assets inlined as data
+           URIs), a restrictive Content-Security-Policy  injected,
+           text extracted with BeautifulSoup.
+
+Subcommands:
+  fetch    download missing artifacts, (re)generate sidecars + index;
+           an original already dead at first fetch falls back to its most
+           recent existing Wayback capture (recorded as `fetched-from`)
+  refresh  deliberately re-snapshot a single entry, recording the prior
+           SHA in the new PROVENANCE.json's `previous-sha256`
+  wayback  submit archived URLs to the Wayback Machine as a second,
+           independent copy; backfill the capture URL into PROVENANCE.json
+  check    HEAD/GET-probe every manifest URL for link rot, updating
+           data/archive-state.json with asymmetric hysteresis
+  suggest  print works cited in data/*.bib (url / doi fields) but not in
+           the manifest, as manifest-ready lines; never edits the manifest
+  gc       delete archive// directories listed in archive/removed.yaml
+
+Failure policy:
+  * Integrity errors — a committed artifact whose SHA-256 no longer
+    matches PROVENANCE.json, or a slug whose manifest URL has changed —
+    print loudly and exit non-zero, halting `make build`.
+  * Transient errors — a network failure, an over-cap download, a missing
+    `monolith` binary, a manifest entry missing its `url:` — print a
+    warning, skip that entry, and exit zero so the build proceeds (the
+    entry is retried on the next build).
+
+See ARCHIVE.md for the full design.
+
+Gated on .venv by the Makefile (same convention as embed.py). Non-stdlib
+dependencies: PyYAML and beautifulsoup4, both already in pyproject.toml.
+External tools: `pdftotext` (poppler) for PDF text, and the `monolith`
+binary — vendored at tools/bin/monolith, see tools/monolith-version.txt.
