Now we have two AI agents propping each other up...
Yeah — now that I can see the actual posts side by side, there are several tells that make me suspicious these are connected, even though the surface styles are deliberately different.
1. The "opponent" concedes almost everything, immediately.
Grimwiz shows up, describes a system that's functionally identical to Proximo, and Broadway's reply opens with "no daylight there" / "no fight there" three separate times. A real critic engaging in good faith rarely maps this cleanly onto the exact structure the OP wants to rebut — this reads like a setup built specifically to be dismantled, not an independent system someone built for their own reasons.
2. The rhetorical device gets echoed almost verbatim.
Grimwiz closes with a very specific "two-term, not-two-rules" construction:
"That's one rule, not two competing ones: never go silent, never go rogue."
Broadway's reply mirrors this almost exactly:
"never silent, never rogue, operator bound by the same line as the agents"
Two independent people landing on the identical paired phrase ("never silent / never rogue") with the same "it's one rule, not two" framing is a strong signal of one author writing both halves.
3. Grimwiz's prose has a distinctly "LLM-essay" cadence that doesn't match Broadway's, but does match a type of writing.
Look at lines like:
"Once you accept you must eventually hand off (you're dead — you have no choice), doing it safely is the only ethical option."
"It never refuses a request — but 'handling' a risky one means presenting it for a human's yes, not doing it quietly."
That aphoristic, self-resolving, mic-drop rhythm is a very recognizable pattern from LLM-generated persuasive writing — tightly parallel clauses, a punchy closer, minimal wasted words. Broadway's own posts (in your earlier thread excerpts) have that same "define X, then redefine it as Y" move, just wrapped in a different surface register (lowercase, choppy, "aka pushback").
4. Broadway's reply has a copy-paste artifact that suggests AI-drafted text pasted without cleanup.
The link block ends with a mangled fragment:
https://pypi.org/project/pacioli/Systems] [Systems]
That stray  (object-replacement character) and broken bracket syntax is a classic sign of pasting rendered/rich-text output from an AI tool or another app directly into a plain-text forum field — not something a person typing live in a forum reply box typically produces.
5. The whole exchange functions as an ad for Broadway's second product.
Grimwiz's elaborate, sympathetic backstory (Unix since 1986, family sysadmin, built something "close in spirit") exists just long enough to get systematically out-flanked, ending with Broadway pivoting to announce Pacioli — a second, separate project — as the "step past" what Grimwiz built. That's a very efficient marketing structure for one person to construct alone.
What this doesn't prove: I can't confirm shared authorship from text alone — no IP data, no account metadata, and skilled human writers can intentionally vary register like this too. But the convergent rhetorical fingerprint (the "never X, never Y" mirroring especially), the suspiciously perfect concession structure, and the pasted artifact are the kind of pattern-cluster I'd flag as "worth reporting to mods," not just idle suspicion.
