Commuted-Telegraphy 0.4.3

A data-driven story brief generator for the Commuted fiction universe.

Telegraphy

Telegraphy is a Python package and command-line tool for generating structured story briefs from a versioned, data-driven canon dataset.

It exposes two user-facing entry points:

• story-brief (CLI)
• telegraphy-gui (desktop GUI)

Telegraphy does not write prose. It generates the feedstock: YAML front matter, scenario constraints, style guidance, date-aware character and setting selections, optional sexual-content metadata, and a Markdown drafting scaffold. The result is a repeatable prompt artifact that can be copied into a writing workflow or saved as a Markdown seed file.

What is this?

Telegraphy is the focused story-brief generator for the Commuted fiction universe.

At a practical level, it is:

• a Python package named telegraphy;
• a CLI named story-brief;
• a packaged JSON dataset under telegraphy/story_brief/data/;
• validation and linting tools for keeping that dataset usable;
• tests and CI for preserving deterministic generation behavior.

A generated brief includes:

• title;
• protagonist and secondary character;
• date;
• setting;
• weather;
• central conflict;
• inciting pressure;
• ending type;
• style guidance;
• sexual content level;
• sexual partner metadata when applicable;
• sexual scene tags when applicable;
• word-count target;
• a Markdown story-draft heading.

The generator is date-aware. Character availability, setting availability, and partner distributions are constrained by configured date ranges. That is the point of the tool: it lets the fiction machine throw sparks without setting the continuity barn on fire.

Install

Telegraphy requires Python 3.12 or newer.

For normal local use from a clone:

git clone https://github.com/jeffreywevans/Telegraphy.git
cd Telegraphy
python -m pip install -e .

For development:

python -m pip install -e ".[dev]"

The development extra installs the tools used by the repository:

• pytest
• pytest-cov
• ruff
• mypy
• types-PyYAML

You can verify that the CLI is available with:

story-brief --help

You can also run it as a module:

python -m telegraphy.story_brief --help

You can verify that the GUI launcher is available with:

telegraphy-gui --help

If you prefer module execution:

python -m telegraphy.gui.tablet_app

Quickstart

Print a generated brief to the terminal:

story-brief --print-only

Generate a reproducible brief for a specific date:

story-brief --seed 42 --date 2000-01-01 --print-only

Write a brief to the default output directory:

story-brief

By default, Telegraphy writes Markdown files under:

output/story-seeds/

Use an explicit filename:

story-brief --filename brief.md

Overwrite an existing file only when you mean it:

story-brief --filename brief.md --force

Run dataset linting without generating a brief:

story-brief --lint-dataset

Example clean report:

Dataset lint: no blocking coverage gaps found.
Dataset lint: no warnings.

Run strict validation before generation:

story-brief --validate-strict --print-only

GUI quickstart

Start the GUI:

telegraphy-gui

Press GENERATE! to run the same generator used by the CLI (python -m telegraphy.story_brief --print-only).

Use the Seed and Date fields to forward --seed and --date to the CLI for reproducible GUI runs.

Press COPY! to copy the most recent successful brief to your clipboard.

Using the GUI

The 0.4.3 GUI is intentionally focused: it is a tablet-shaped desktop wrapper around the existing story-brief engine.

What happens when you click GENERATE!

1. The GUI disables both buttons to avoid overlapping runs.
2. It starts a background worker thread so the window stays responsive.
3. The worker executes: python -m telegraphy.story_brief --print-only.
4. On success, the generated Markdown is displayed in the output pane and cached as the latest output.
5. On failure, stderr/stdout diagnostics are shown in the output pane and copy is disabled for empty output.

GUI layout

• Header: app title and subtitle.
• Toolbar:
  • GENERATE!: run generation.
  • COPY!: copy last successful output.
  • Status: live state (Ready, Generating, Generated, Failed, Copied).
• Output pane: read-only text area with scrollbar showing Markdown output or errors.

GUI behavior details

• Uses your local Python interpreter (sys.executable) and inherited environment (os.environ) by design; this is convenient for virtualenv workflows, but also means local environment changes can alter behavior.
• GUI CLI worker has a default 30-second timeout (override with telegraphy-gui --timeout <seconds>).
• telegraphy-gui --help is supported without launching a window.
• In headless environments, startup fails cleanly with a user-facing error instead of a tkinter traceback.
• Decodes CLI output using your preferred locale encoding, then falls back to UTF-8 with replacement for robust display.
• Never writes files directly; it always requests --print-only output from the CLI.
• Clipboard copy only works after a successful generation.

GUI troubleshooting

• If telegraphy-gui fails to launch, ensure tkinter is available in your Python build.
• If generation fails, read the output pane: the GUI surfaces the underlying CLI error message.
• For reproducible debugging, run the CLI directly with explicit flags (for example story-brief --seed 42 --date 2000-01-01 --print-only).

CLI examples

CLI reference

Option	Purpose
--print-only	Print Markdown to the terminal and skip file writing.
--seed <int>	Use deterministic randomness for reproducible briefs; omit it to use OS-backed entropy.
--date YYYY-MM-DD	Force the story date for scenario testing.
-o, --output-dir <path>	Choose the output directory. Defaults to output/story-seeds.
--filename <name.md>	Choose the output filename.
--force	Allow overwriting an existing output file.
--validate-strict	Validate date-range generation preconditions before generating.
--lint-dataset	Run dataset lint diagnostics and exit.
-h, --help	Show command help.

Print only

Use this when you want to copy the generated prompt directly from the terminal.

story-brief --print-only

Reproducible generation

Seeded output is intended for debugging, tests, reviews, and repeatable creative workflows.

story-brief --seed 8675309 --print-only

Lock both the random seed and the story date:

story-brief --seed 42 --date 2000-01-01 --print-only

That command produces Markdown shaped like this:

---
title: It's Only Profound if You're Not Stoned
protagonist: Cremeans
secondary_character: Bill Davenport
time_period: '2000-01-01'
setting: Lenovo Center - Raleigh, NC, USA
weather: lousy
sexual_content_level: none
sexual_partner: null
sexual_scene_tags: []
word_count_target: 6000
---

# It's Only Profound if You're Not Stoned

## Story Draft

*Write a story of approximately 6000 words using the YAML brief above.*

Write to a specific directory

story-brief --output-dir output/story-seeds

The output directory is resolved under the current working directory. Telegraphy intentionally refuses output paths that escape that tree.

Pick the filename

story-brief --filename "first-pass.md"

Filenames are sanitized and checked for cross-platform safety. Telegraphy rejects path separators, dot-segments, leading or trailing spaces, Windows device names, and other file-system traps.

Validate before generating

story-brief --validate-strict --seed 42 --date 2000-01-01 --print-only

Strict validation checks generation preconditions across the configured date range before creating output.

Lint the dataset

story-brief --lint-dataset

Linting emits a concise report and exits without generating a brief.

A clean dataset reports:

Dataset lint: no blocking coverage gaps found.
Dataset lint: no warnings.

Data override

Telegraphy ships with its canonical dataset inside the package:

telegraphy/story_brief/data/

The packaged dataset contains five required JSON files:

config.json
entities.json
partner_distributions.json
prompts.json
titles.json

For experiments, alternate timelines, review fixtures, or private datasets, point Telegraphy at another directory:

TELEGRAPHY_DATA_DIR=/absolute/path/to/story-data story-brief --print-only

TELEGRAPHY_DATA_DIR is the only supported environment variable override. The legacy COMMUTED_STORY_BRIEF_DATA_DIR override was removed and is intentionally ignored.

Override directories must:

• be absolute paths after optional current-user ~ expansion;
• already exist;
• contain all five required JSON files;
• avoid parent-directory traversal;
• avoid ~user expansion;
• avoid NUL bytes.

Only the known dataset filenames are loaded. Telegraphy refuses unknown data-file requests and checks that resolved files remain inside the configured data directory.

Data-file responsibilities

titles.json contains title templates. Supported title tokens are:

@protagonist
@setting
@time_period

entities.json contains date-bounded character and setting availability.

prompts.json contains narrative prompt pools such as conflicts, pressures, endings, style guidance, and weather.

config.json contains schema metadata, dataset version, date range, output key order, word-count targets, sexual-content options and weights, tag groups, and the writing preamble.

partner_distributions.json contains date-aware weighted partner pools by protagonist. An empty partner list means intentional celibacy for that era. A missing era means absent data and should be treated as a dataset problem.

Validation and linting

Telegraphy has two related safety nets: validation and linting.

Validation checks whether the dataset can be loaded and normalized. It rejects malformed schema, missing keys, unsupported title tokens, overlapping availability windows for the same entity, invalid dates, broken weight tables, bad ordered keys, invalid partner distributions, and other hard failures.

Strict validation goes farther:

story-brief --validate-strict --print-only

It checks date-range generation preconditions at availability checkpoints, including:

• at least two distinct available characters for each checked date;
• at least one available setting for each checked date.

Linting looks for dataset coverage gaps and fragile areas:

story-brief --lint-dataset

Lint exits with code 0 when no blocking issues are found and code 1 when the report contains errors. Strict validation also exits nonzero on hard failures.

Use linting before committing dataset edits. Use strict validation before trusting a new or heavily edited dataset.

A good minimum review loop for data changes is:

story-brief --lint-dataset
story-brief --validate-strict --seed 42 --date 2000-01-01 --print-only
pytest -q tests/story_brief

Software bill of materials (SBOM)

Telegraphy ships a CycloneDX SBOM at:

sbom.cdx.json

You can use this file for dependency transparency, supply-chain review, and security tooling that ingests CycloneDX JSON.

To regenerate the SBOM after dependency or version changes:

python -m telegraphy.scripts.generate_sbom

The repository includes sbom.cdx.json in source distributions via MANIFEST.in.

How the generator works

Telegraphy follows a small, deliberate pipeline:

JSON dataset
    -> data_io.load_data()
    -> validation.validate_story_data()
    -> normalized StoryData
    -> generation.pick_story_fields()
    -> rendering.to_markdown()
    -> terminal output or safe Markdown write

The main modules are:

Module	Responsibility
telegraphy.story_brief.cli	Argument parsing and CLI orchestration.
telegraphy.story_brief.data_io	Dataset discovery, package resources, environment overrides, JSON loading, cache management.
telegraphy.story_brief.validation	Schema validation, semantic validation, strict date-range preconditions.
telegraphy.story_brief.linting	Dataset coverage diagnostics and human-facing lint reports.
telegraphy.story_brief.generation	Date selection, availability filtering, weighted choices, field selection.
telegraphy.story_brief.partner_models	Partner-distribution parsing and date-aware weighted partner pools.
telegraphy.story_brief.rendering	YAML front matter and Markdown output.
telegraphy.story_brief.filenames	Slugging, filename sanitization, output-path safety, write protection.
telegraphy.story_brief.generate_story_brief	Compatibility facade over the refactored implementation.

Seeded generation is designed to be stable. When you supply --seed, Telegraphy uses a deterministic random source and sorted selection pools so that the same inputs produce the same brief.

When no seed is supplied, Telegraphy uses secrets.SystemRandom, so unseeded runs draw OS-backed entropy instead of using a deterministic PRNG.

Output files and safety

Telegraphy is conservative about writes.

By default it writes into:

output/story-seeds/

It refuses to overwrite existing files unless --force is provided.

It confines output to the current working directory tree. This is intentional: generated files should not be able to wander out of the project and bite the furniture.

It also performs filename checks and sanitization, including:

• cross-platform unsafe characters;
• path separators;
• dot-segments;
• leading or trailing spaces;
• Windows reserved device names;
• UTF-8 byte-length limits;
• optional O_NOFOLLOW protection on platforms that provide it.

Development

Create and activate a virtual environment, then install the development extra:

python -m pip install -e ".[dev]"

Run the local quality checks:

ruff check .
ruff format .
mypy telegraphy
pytest

Install tox if it is not already available:

python -m pip install tox

Run the full tox workflow:

tox -e py312

Run fast tests only:

tox -e py312-fast

Run slow or integration tests:

tox -e py312-slow

The repository uses:

• Ruff for linting and formatting;
• mypy in strict mode for the package;
• pytest for the test suite;
• pytest-cov and coverage settings for branch coverage;
• tox for repeatable local test environments;
• GitHub Actions for CI;
• SonarQube Cloud for quality reporting.

GitHub Actions pinning policy

This repository has a strong preference for pinning GitHub Actions to immutable commit SHAs. Pinned SHAs reduce supply-chain risk from mutable tags and make CI behavior easier to reproduce.

Where practical, workflow uses: references should follow this style:

- uses: owner/action@<40-character-commit-sha> # v1.2.3

In a small number of cases, we intentionally keep a trusted GitHub-maintained action (for example, from the actions/ or github/ organizations) on a major tag (for example @v4) instead of a SHA. When we do this, the trade-off is explicit: the repository chooses to trust GitHub's managed release process for that core toolchain, and to accept the small reduction in strict immutability in exchange for simpler maintenance.

Project metadata

The package metadata lives in pyproject.toml.

Current package facts:

Field	Value
Package	telegraphy
Current version	0.4.3
Python	>=3.12
Runtime dependency	PyYAML>=6.0.3
Console script	story-brief = telegraphy.story_brief.cli:main
License	MIT

Contribution expectations

Before opening a pull request, run the relevant checks and include the commands you ran in the PR notes.

For code changes, include tests that cover success and failure behavior.

For dataset changes, keep diffs focused and run:

story-brief --lint-dataset
story-brief --validate-strict --print-only

For generation changes, preserve deterministic seeded behavior unless the PR explicitly and intentionally changes it.

Release notes and status

Current status: 0.4.3.

This release establishes the 0.4.3 line, preparing for PyPI Trusted Publishing plus follow-up build consistency updates across metadata, docs, and SBOM artifacts.

Highlights:

• launched the desktop telegraphy-gui command with a tablet-style interface backed by the existing CLI engine;
• strengthened GUI reliability with threaded generation flow, robust subprocess decode fallback, and expanded GUI unit coverage;
• kept package metadata, changelog references, README status text, and SBOM artifact versioning aligned for build consistency.

See CHANGELOG.md for release notes.

Stability note

Telegraphy is usable as a local CLI and developer tool. The command-line interface and data schema are still young enough that maintainers should treat changes carefully and document migration impact in PRs.

No published package distribution is assumed by this README. Install from the repository unless and until a release workflow says otherwise.

Troubleshooting

story-brief is not found

Install the package in the current environment:

python -m pip install -e .

For development:

python -m pip install -e ".[dev]"

Then retry:

story-brief --help

The selected date is rejected

The date must be inside the configured dataset range. Use ISO format:

story-brief --date 2000-01-01 --print-only

The data override is rejected

Check that the override is absolute and contains the required JSON files:

ls /absolute/path/to/story-data

Expected files:

config.json
entities.json
partner_distributions.json
prompts.json
titles.json

An output file already exists

Telegraphy will not overwrite files by accident. Use another filename or pass --force:

story-brief --filename brief.md --force

Output path is rejected

Keep --output-dir inside the current working directory tree. Absolute paths are allowed only when they resolve inside that tree.

Linting passes but generation still fails

Run strict validation:

story-brief --validate-strict --print-only

Linting reports dataset health. Strict validation checks generation preconditions across key date boundaries.
