infrastructure-gemini-cdp

Gemini adapter via Chrome DevTools Protocol: the composer is found by an ordered, ratified candidate list and a miss is a typed refusal naming what was tried; prompts go in as trusted input (Input.insertText, Input.dispatchMouseEvent), never Runtime.enable. B-086 step 2.

What it is for

Gemini adapter via Chrome DevTools Protocol (B-086 step 2).

The composer is found by an ordered, ratified candidate list (candidates::COMPOSER_CANDIDATES), tried in order inside one Runtime.evaluate; the outcome names the candidate that matched, or is a typed refusal carrying every candidate tried. Nothing here guesses.

Input is trusted: text goes in through Input.insertText after the matched element is focused, and the send button is clicked with Input.dispatchMouseEvent at its bounding-box centre. The CDP safety policy in docs/research/PRIVACY_RESEARCH_SYSTEM.md holds: no Runtime.enable, no Page.addScriptToEvaluateOnNewDocument, no user-agent override.

Requires Chrome running with --remote-debugging-port and a logged-in Gemini tab open.

Public surface

`candidates`

Item	What it is
`pub struct Candidate`	One thing to try, by name, with the CSS that tries it.
`pub const COMPOSER_CANDIDATES: & Candidate`	Composer candidates, in ratified order.
`pub const SEND_CANDIDATES: & Candidate`	Send-button candidates, in ratified order.
`pub struct Rect`	Bounding box of the matched element, viewport CSS pixels.
`Rect :: fn centre(& self) ->(f64, f64)`	Where a trusted click lands.
`pub struct ComposerMatch`	The candidate that matched, with what the page said about the element.
`pub enum ProbeOutcome`	What the probe found.
`fn probe_js(cands : & Candidate) -> String`	Build the one expression that tries `cands` in order and returns JSON
`fn parse_probe(raw : & str) -> Result <ProbeOutcome, String>`	Parse what the page returned from `probe_js`.

Boundary

Depends on no other workspace tier.

Shares tier infrastructure with 82 other crates: infrastructure-acquire, infrastructure-adapters-google-calendar, infrastructure-adapters-google-gmail, infrastructure-adapters-google-places, infrastructure-adapters-google-trends, infrastructure-adapters-shodan, infrastructure-adapters-yelp, infrastructure-agent, … (82 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._

Feature flags

No Cargo features are defined: every capability is unconditional, so no consumer can receive a half-wired crate.

Targets

Kind	Name	Source
bin	`gemini-cdp`	`src/bin/gemini-cdp.rs`
lib	`infrastructure_gemini_cdp`	`src/lib.rs`

Error model

No public error type was detected: no public item declares a type named *Error, and no public signature returns one.

Operational characteristics

Property	Evidence
async public surface	none detected
async runtime	none detected
database access	none detected
network I/O	none detected
unsafe code	none detected
environment variables	none detected

No unsafe block, unsafe fn, unsafe impl or unsafe trait was found by the parser anywhere in this crate's source.

Configuration

No environment variable is read with a literal name anywhere in this crate. A variable whose key is computed at run time cannot be listed here, and is not claimed to be absent.

No workspace crate depends on this one.
