ML Input → Output — H-Bracket Transformation Concepts
The H as a transformation gate • 8 variants • 100 / 32 / 16px • both polarities
The shift: the input→output idea is now the construction logic of the H, not blocks added to it. Left stem = input (open/fragmented), centre crossbar = the model/processing gate, right stem = output (solid/resolved). Left→right transformation without arrows.
Every cue is engineered to simplify into a bold bracket-H at 16px; htx-v7-favicon-master is the dedicated small-size carrier.

RationaleThe clearest mapping of the idea onto the H's three zones; the baseline.
I/O transformationFragmented left stem (input) vs. solid right stem (output) — the verticals literally change state.
Model / processingThe dominant bold crossbar is the model the signal passes through.
16px legibilityStrong; left gaps close into a solid stem, reads as a clean H.
RiskLeft gaps can read as "broken" if scaled with too much contrast; keep gaps modest.
RecommendationReliable primary; compare head-to-head with V8.

RationaleTreats the crossbar as a funnel — the most active "processing" read.
I/O transformationA wide split mouth (many inputs) narrows to one solid output block: many→one.
Model / processingThe narrowing throat IS the compression/model step, geometric not illustrated.
16px legibilityFair; mouth cuts close to a solid funnel — still a legible H bar.
RiskMost complex silhouette; the funnel can read as a play/arrow shape if over-tapered.
RecommendationDistinctive large-format option; watch the arrow-adjacency.

RationaleIntroduces a central vertical gate — a literal threshold the signal crosses.
I/O transformationThin pre-process bar (left) vs. thick post-process bar (right), divided by the gate.
Model / processingThe tall central gate is the model/threshold function; it anchors the asymmetry.
16px legibilityRisky; the thin left bar and the gate can merge, muddying the crossbar.
RiskThe vertical gate slightly fights the H's two verticals; can read as three uprights.
RecommendationConceptually strong but the weakest H-read; large sizes only.

RationaleKeeps stems calm and puts all the meaning in a hero crossbar.
I/O transformationThin input segment steps up to a bold output segment across one cut.
Model / processingThe single cut is the processing point; the step is the resolved gain.
16px legibilityGood; the small gap closes and the stepped bar holds the H.
RiskSubtle — at a glance it can read as a plain H with a slightly uneven bar.
RecommendationElegant, restrained; a strong quiet alternative to V8.

RationaleEncodes the brand story — bracket syntax becoming structure — into one mark.
I/O transformationLight open bracket (left) resolves into a heavy closed letter-post (right).
Model / processingThe crossbar is the bridge that carries weight from syntax to structure.
16px legibilityGood; the weight asymmetry survives, both verticals stay present.
RiskAsymmetric weight can look unbalanced/unstable rather than intentional.
RecommendationMost ownable concept; needs careful optical balancing in Illustrator.

RationaleThe most minimal, premium take — output expressed by absence.
I/O transformationSolid input mass (left of bar) vs. a carved, defined output unit (right of bar).
Model / processingThe bar is the process; the void is the structured result it produces.
16px legibilityStrong silhouette; the void shrinks to a bold H below ~22px.
RiskThe single void can read as a generic "play/stop" UI cut if proportions slip.
RecommendationBest calm/premium hero; pair with V7 for small sizes.

RationaleBuilt to win at 16px: heaviest silhouette, one robust cue.
I/O transformationA connected step in the bar — thin input rising to thick output.
Model / processingThe step is the processed gain; no gap means it never disintegrates.
16px legibilityBest of the set; reads instantly in both polarities.
RiskMost reduced meaning; relies on the family to carry the full story.
RecommendationAdopt as the favicon / app-icon master.
