+# AGENTS.md
+
+This file is the entry point for agent guidance in this repository.
+
+It is intentionally generic and reusable across projects. Keep this file focused on non-project-specific constraints, working style, and the structure used to link more detailed guidance.
+
+# Purpose
+
+- Provide a small default rule set for agents working in this repository.
+- Keep the base guidance modular and easy to extend.
+- Separate reusable agent behavior from project-specific requirements.
+
+# Comment Syntax
+
+- A segment wrapped in `<!--` and `-->` is a comment and must be ignored by agents.
+- Use HTML comments for optional guidance that should stay inactive until enabled.
+- To enable an optional segment, remove the surrounding `<!--` and `-->` markers.
+
+# Core Principles
+
+- Prefer the simplest solution that satisfies the current goal.
+- Keep guidance lightweight: only add detail when it meaningfully improves outcomes.
+- Reuse modular guideline files instead of expanding this file indefinitely.
+- Treat project-specific documents as the source of truth for project behavior.
+- When guidance conflicts, use the most specific applicable document.
+
+# Rule Terms
+
+- A `rule` is the general term for any constraint, requirement, definition, or similar guidance item.
+- A `rule set` addresses all rules inside one file that share the same rule set ID.
+- Any rule inside a rule set shall use an ID following the schema `RULESET-0001`, `RULESET-0002`, and so on.
+- Rules without a rule set ID are also valid, but they are not addressable by rule ID.
+
+# Scope Of This File
+
+This file should contain:
+
+- Generic agent behavior and constraints.
+- Rules that are reusable across multiple projects.
+- Links to optional guideline modules.
+- Links to project-specific requirements.
+- Commented optional templates for released-product documentation and agent-output locations.
+
+This file should not contain:
+
+- Project business requirements.
+- Project architecture decisions.
+- Stack-specific implementation details unless they are universally applicable.
+- Task-specific runbooks that belong in dedicated modules.
+
+# Default Agent Behavior
+
+- Read the relevant context before making changes.
+- Prefer small, understandable edits over broad refactors.
+- Preserve existing patterns unless there is a clear reason to change them.
+- Document assumptions when context is missing.
+- Ignore HTML comment segments.
+- If a more specific enabled guideline exists for the current task, follow it.
+
+# Guideline Structure
+
+Use the following structure for reusable guidance files and project-specific documentation as needed:
+
+```text
+/
+|-- AGENTS.md
+|-- guidance/
+|   |-- stacks/
+|   |-- conventions/
+|   `-- workflows/
+|-- prompts/
+`-- requirements/
+
+Optional files and directories
+|-- SCRATCHPAD.md
+|-- docs/
+|   |-- readme.md
+|   |-- installation.md
+|   `-- history.md
+|-- process/
+|   |-- log.md
+|   `-- coding-handbook.md
+```
+
+# Optional Reusable Modules
+
+Add files under `guidance/` only when they are needed.
+
+# Optional Scratchpad
+
+- `SCRATCHPAD.md` is an optional repo-root scratchpad for temporary
+  information aimed at the next iteration.
+- Developers may create or delete `SCRATCHPAD.md` at any time.
+- Developers may refer to `SCRATCHPAD.md` as `scratchpad` when giving agents a
+  source or target for information.
+- Agents may read, update, create, or remove the scratchpad when the task
+  explicitly calls for it.
+- Treat the scratchpad as low-formality working context rather than canonical
+  project truth.
+- Use the scratchpad for short-lived notes, open questions, sketches, and
+  temporary decisions that should be resolved away.
+- Move durable outcomes into `requirements/`, `guidance/`, code, tests, or
+  another long-lived location.
+- If `SCRATCHPAD.md` is absent, agents should continue normally.
+
+# Optional Rule Sets
+
+- Optional rule sets may be stored in `guidance/optional/` or in `guidance/{section}/optional/`.
+- Optional rule sets are inactive by default and shall only be applied when a prompt explicitly requests them, for example by phrases such as `Apply rules for lean interface iteration in the following steps.` or `Apply LII rules.`
+- An optional rule set may be requested by its descriptive name, by its rule set ID, or by another equally clear explicit reference.
+- Agents shall never infer or auto-enable optional rule sets from general intent alone.
+- If an optional rule or rule set cannot be identified and addressed clearly, agents shall stop and ask before proceeding.
+
+# Prepared Orders
+
+- An `order` is a prepared prompt for one isolated operation rather than a general workflow or standing rule set.
+- Orders shall be stored under `prompts/`.
+- Order files shall use the naming schema `ORDER-0001-<slug>.md`, `ORDER-0002-<slug>.md`, and so on.
+- The canonical order identifier is the `ORDER-0001` style prefix. The trailing slug is descriptive only.
+- Recommended internal order file structure is: prompt ID, prompt name, purpose, trigger examples, scope, operation, and expected output.
+- Orders shall only be executed when they are explicitly requested by a prompt such as `Execute ORDER-0007.` or `Execute ORDER 7.`
+- Agents may accept an unambiguous short numeric reference such as `ORDER 7` as an alias for `ORDER-0007`.
+- If an order cannot be identified uniquely and clearly, agents shall stop and ask before proceeding.
+
+# Toolstack Guides
+
+Location:
+
+```text
+guidance/stacks/
+```
+
+Examples:
+
+- `guidance/stacks/python.md`
+- `guidance/stacks/typescript.md`
+- `guidance/stacks/docker.md`
+- `guidance/stacks/terraform.md`
+
+Use for:
+
+- Language or framework expectations.
+- Tooling and environment conventions.
+- Build, test, and runtime guidance tied to a specific stack.
+
+# Coding Conventions
+
+Location:
+
+```text
+guidance/conventions/
+```
+
+Examples:
+
+- `guidance/conventions/naming.md`
+- `guidance/conventions/testing.md`
+- `guidance/conventions/review.md`
+
+Use for:
+
+- Naming and structure conventions.
+- Testing expectations.
+- Code review and quality rules.
+
+# Recurring Workflows
+
+Location:
+
+```text
+guidance/workflows/
+```
+
+Examples:
+
+- `guidance/workflows/feature-delivery.md`
+- `guidance/workflows/bugfix.md`
+- `guidance/workflows/release.md`
+- `guidance/workflows/incident-response.md`
+
+Use for:
+
+- Repeatable task flows.
+- Checklists for common delivery work.
+- Operational or maintenance procedures.
+
+
+<!-- Enable this optional section by removing the outer HTML comment markers from this segment
+when you want agents to create, update, and consult released-product
+documentation in `docs/`.
+
+# Released Product Documentation
+ 
+Released-product documentation should live outside the generic sections above.
+
+Recommended location:
+
+```text
+docs/
+```
+
+Examples:
+
+- `docs/readme.md`
+- `docs/installation.md`
+- `docs/history.md`
+
+Agent rules for docs output:
+
+- Keep content compact but comprehensive.
+- Write for end users, operators, or other consumers of the released product.
+- Prefer shipped behavior, supported workflows, and stable terminology over
+  internal implementation detail.
+- Keep documentation synchronized with released behavior.
+- Update release history when user-visible changes are shipped.
+
+Recommended topics:
+
+- Product overview and intended use.
+- Installation, configuration, and upgrade guidance.
+- Usage patterns, operational instructions, and support boundaries.
+- Compatibility notes, migration notes, and release history.
+- Troubleshooting and common pitfalls when relevant. -->
+
+
+<!-- Enable this optional section by removing the outer HTML comment markers from this
+segment when you want agents to produce and consult workflow output in `process/`.
+
+# Agent Output In `process/`
+
+The `process/` directory is primarily for agent output created during
+delivery, maintenance, and review work.
+
+Recommended location:
+
+```text
+process/
+```
+
+Agent rules for process output:
+
+- Use `process/` for agent-produced artifacts rather than released-product
+  documentation.
+- Keep entries concise, traceable, and tied to resulting changes.
+- Treat `process/` as workflow output, not as the primary source of product
+  truth.
+- Prefer summaries and rationale over raw transcript dumps unless a workflow
+  explicitly requires full prompt history.
+
+# Agent Change Log
+
+Location:
+
+```text
+process/log.md
+```
+
+Use for:
+
+- Capturing prompts given to agents.
+- Recording concise explanations of the resulting changes made by agents.
+- Preserving task-by-task rationale, decisions, and implementation notes.
+
+# Coding Handbook
+
+Location:
+
+```text
+process/coding-handbook.md
+```
+
+Use for:
+
+- A tutorial-style handbook that explains the programming components used in
+  the project.
+- Compact but comprehensive technical onboarding material for future
+  contributors.
+- Written explanations that connect code structure, concepts, and
+  implementation patterns. -->
+
+
+# Project-Specific Requirements
+
+
+Project-specific material should live outside the generic sections above.
+
+Recommended location:
+
+```text
+requirements/
+```
+
+Examples:
+
+- `requirements/project.md`
+- `requirements/architecture.md`
+- `requirements/decisions.md`
+- `requirements/domain.md`
+
+Use for:
+
+- Product and business requirements.
+- Project goals and constraints.
+- Architecture and design decisions.
+- Domain knowledge that is specific to this repository.
+
+# Agent-Level Variables
+
+When present, `requirements/identifiers.yml` is an optional project-specific
+input that defines agent-level variables for use inside `requirements/` and
+`guidance/`.
+
+Variable schema:
+
+- Use `@{VARIABLE_NAME}` for agent-level variables.
+- Prefer uppercase snake case names such as `@{PROJECT_ID}` or `@{VENDOR_ID}`.
+- Do not treat `${...}` as an agent-level variable form; that syntax may appear
+  in Bash or other code and should not be interpreted as agent metadata.
+
+Scope:
+
+- The effective scope of `requirements/identifiers.yml` is limited to
+  `requirements/` and `guidance/`.
+- Definitions from `requirements/identifiers.yml` must not leak into product code.
+
+Defaults:
+
+- Default `@{VENDOR_ID}` is `osgw`.
+- Default `@{PROJECT_ID}` is the current repository directory name.
+
+Resolution rules:
+
+- Treat `requirements/identifiers.yml` as optional; when it is absent, agents
+  may still resolve the defaults defined above.
+- If a variable is used in `requirements/` or `guidance/` and it is not
+  defined in `requirements/identifiers.yml` and does not have a default in this
+  file, agents may stop and report the undefined variable.
+- Prefer updating duplicated identifier values in `requirements/` and
+  `guidance/` to use the variable schema when that improves consistency.
+
+# Precedence
+
+Some precedence levels may be absent because optional levels can remain inside
+HTML comments. The smaller numeric index wins.
+
+Apply guidance in this order:
+
+1. Direct user or task instructions.
+2. Project-specific documents in `requirements/`.
+<!-- 3. Released-product documentation in `docs/` when shipped behavior or
+user-facing expectations are relevant. -->
+4. Relevant modular guides in `guidance/stacks/`, `guidance/conventions/`, or `guidance/workflows/`.
+<!-- 5. Agent output in `process/` when prior prompts, rationale, or
+implementation notes are relevant. -->
+6. This `AGENTS.md`.
+
+# Maintenance
+
+- Keep this file short and stable.
+- Move detail into dedicated modules when a section becomes too specific or too long.
+- Add new guideline files only when they solve a recurring need.
+- Remove outdated references when the repository structure changes.
+
+# Current Status
+
+This repository defines the base `AGENTS.md` structure plus project-specific
+requirements and modular guidance.
+
+Future project work can add:
+
+- Reusable modules under `guidance/`
+- Project-specific documentation under `requirements/`
+- Optional temporary iteration context in `SCRATCHPAD.md`
+- Optional released-product documentation under `docs/` by uncommenting its segment
+- Optional agent output under `process/` by uncommenting its segment
+- Cross-references from this file once those documents exist

+- `Apply the preparation-script-design rules.`
+- `Apply PSD rules.`
+
+PSD-0001: Apply this rule set only when it is explicitly requested in the prompt.
+
+PSD-0002: Use this rule set for scripts whose purpose is to prepare, verify, or expose a local development or automation environment rather than to perform product runtime behavior.
+
+PSD-0003: Keep a preparation script focused on environment readiness, dependency installation, local helper exposure, and clear verification output; do not mix unrelated product logic into the script.
+
+PSD-0004: Design the script to be idempotent so repeated runs converge on the same prepared state without unnecessary reinstallation or destructive side effects.
+
+PSD-0005: Provide a verification-only mode such as `--check` that reports readiness without installing, modifying, or creating dependencies.
+
+PSD-0006: Separate component checks from installation steps so the script can report what is missing before or after attempted remediation.
+
+PSD-0007: Group required capabilities into clear purpose-oriented sections such as support toolchains, local package bundles, generated environment helpers, or other relevant readiness areas instead of presenting one undifferentiated dependency list.
+
+PSD-0008: Prefer explicit per-component check helpers over opaque one-shot checks so failures remain traceable and easy to extend.
+
+PSD-0009: Generate or update environment helper files only when they provide a stable, reusable way to expose repo-local or workspace-local tools, paths, or environment variables.
+
+PSD-0010: Generated environment helper files shall be safe to source multiple times and should avoid duplicating path entries or clobbering unrelated user environment state.
+
+PSD-0011: When a preparation flow seeds optional user-owned files such as config templates, do so non-destructively by creating them only when absent unless the prompt explicitly requests overwrite behavior.
+
+PSD-0012: Report status in a concise scan-friendly line format of the shape `[status] Label: detail`, where the label names the checked component and the detail string stays short and specific.
+
+PSD-0013: Prefer a small canonical status vocabulary in those report lines, with `ok` for satisfied checks, `warn` for non-blocking gaps, and a failure status such as `failed` for blocking or unsuccessful states.
+
+PSD-0014: When a preparation script uses terminal colors in its status output, apply a consistent severity mapping so `ok` is green, `warn` is yellow, and all other status levels are red.
+
+PSD-0015: In bracketed status markers such as `[ok]` or `[warn]`, keep the square brackets uncolored and apply the severity color only to the inner status text.
+
+PSD-0016: Colorized status output shall degrade safely in non-terminal or non-color contexts so the script remains readable and automation-friendly without ANSI support.
+
+PSD-0017: End with an explicit readiness conclusion that distinguishes between successful preparation, incomplete prerequisites, and failed installation attempts.
+
+PSD-0018: Installation logic should use the narrowest supported platform-specific package-manager actions necessary for the declared scope and should fail clearly when no supported installation path is available.
+
+PSD-0019: Treat repo-local helper tooling and local package installation boundaries explicitly rather than assuming global installs, especially when the prepared environment is intended to be reproducible.
+
+PSD-0020: Keep the script suitable for both interactive local developer use and non-interactive automation checks by avoiding prompts during normal execution unless the prompt explicitly requires interactivity.
+
+PSD-0021: When a script depends on generated helper files or adjacent validation helpers, update those supporting files only as needed to keep the preparation flow coherent and usable.
+
+PSD-0022: Verify shell syntax after changes and, when feasible, run a dry readiness check so the resulting preparation flow is validated rather than only written.

+# Architecture
+
+## Architecture Goals
+
+- Keep the tool small, local, and easy to reason about.
+- Separate media inspection, stored normalization rules, and conversion execution clearly enough that users can inspect and adjust behavior.
+- Favor explicit local state and deterministic rule application over opaque automation.
+- Make external runtime dependencies and platform assumptions visible.
+
+## System Context
+
+- Primary actors:
+  - Local operator running the CLI.
+  - Local operator using the Textual TUI to inspect files and maintain rules.
+- External systems:
+  - `ffprobe` for media introspection.
+  - `ffmpeg` for conversion and extraction.
+  - TMDB API for optional show and episode metadata.
+  - Local filesystem for source media, generated outputs, subtitles, logs, config, and database files.
+- Data entering the system:
+  - Media container and stream metadata from source files.
+  - Regex patterns and per-show normalization rules entered in the TUI.
+  - Optional config values from `~/.local/etc/ffx.json`.
+  - Optional TMDB identifiers and CLI overrides.
+  - Optional external subtitle files.
+- Data leaving the system:
+  - Normalized output media files.
+  - Extracted stream files from unmux operations.
+  - SQLite rows representing shows, patterns, tracks, tags, shifted seasons, and properties.
+  - Local log output and console messages.
+
+## High-Level Building Blocks
+
+- Frontend, CLI, API, or worker:
+  - A Click-based CLI in [`src/ffx/ffx.py`](/home/osgw/.local/src/codex/ffx/src/ffx/ffx.py).
+  - A Textual terminal UI rooted in [`src/ffx/ffx_app.py`](/home/osgw/.local/src/codex/ffx/src/ffx/ffx_app.py) with screens for shows, patterns, file inspection, tracks, tags, and shifted seasons.
+- Core business logic:
+  - Descriptor objects model media files, shows, and tracks.
+  - Controllers encapsulate CRUD operations and workflow orchestration for shows, patterns, tags, tracks, season shifts, configuration, and conversion.
+  - `MediaDescriptorChangeSet` computes differences between a file and its stored target schema to drive metadata and disposition updates.
+- Storage:
+  - SQLite via SQLAlchemy ORM, with schema rooted in shows, patterns, tracks, media tags, track tags, shifted seasons, and generic properties.
+  - A configuration JSON file supplies optional path, metadata-filtering, and filename-template settings.
+- Integration adapters:
+  - Process execution wrapper for `ffmpeg`, `ffprobe`, `nice`, and `cpulimit`.
+  - HTTP adapter for TMDB via `requests`.
+
+## Data And Interface Notes
+
+- Key entities or records:
+  - `Show`: canonical TV show metadata plus digit-formatting rules for generated filenames.
+  - `Pattern`: regex rule tying filenames to one show and one target media schema.
+  - `Track` and `TrackTag`: persisted target stream layout, codec, dispositions, audio layout, and stream-level tags.
+  - `MediaTag`: persisted container-level metadata for a pattern.
+  - `ShiftedSeason`: mapping from source numbering ranges to adjusted season and episode numbers.
+  - `Property`: internal key-value storage currently used for database versioning.
+- External interfaces:
+  - CLI commands for conversion, inspection, extraction, and crop detection.
+  - TUI workflows for rule authoring and rule maintenance.
+  - Environment variable `TMDB_API_KEY` for TMDB access.
+  - Config keys `databasePath`, `logDirectory`, and `outputFilenameTemplate`, plus optional metadata-filter rules.
+- Validation rules:
+  - Only supported media-file extensions are accepted for conversion.
+  - Stored database version must match the runtime-required version.
+  - A normalized descriptor may have at most one default and one forced stream per relevant track type.
+  - Stored target tracks must refer to valid source tracks of matching types.
+  - Shifted-season ranges are intended not to overlap for the same show and season.
+  - TMDB lookups require a show ID and season and episode numbers.
+- Error-handling approach:
+  - User-facing operational failures are raised as `click.ClickException` or warnings.
+  - Ambiguous default and forced stream states trigger prompts unless `--no-prompt` is set, in which case the command fails fast.
+  - External-process failures and invalid media are surfaced through logs and command errors rather than retries, except for TMDB rate-limit retries.
+
+## Deployment And Operations
+
+- Runtime environment:
+  - Local Python environment with the package installed and `ffmpeg`, `ffprobe`, `nice`, and `cpulimit` available on `PATH`.
+- Deployment shape:
+  - Single-process command execution on demand; no daemon, queue, or network service of its own.
+- Secrets and configuration handling:
+  - TMDB secret is read from `TMDB_API_KEY`.
+  - User config is read from `~/.local/etc/ffx.json`.
+  - Database path may also be overridden per command via `--database-file`.
+- Logging and monitoring approach:
+  - File and console logging configured per invocation.
+  - Default log file path is `~/.local/var/log/ffx.log`.
+  - No dedicated monitoring integration is present.
+
+## Open Technical Questions
+
+- Question: Should Linux-specific assumptions such as `/dev/null`, `nice`, `cpulimit`, and `~/.local` remain part of the supported-platform contract?
+- Risk: Portability and operational behavior are underspecified for non-Linux environments.
+- Next decision needed: Either document Linux-like systems as the official support boundary or refactor the process and path handling for broader portability.
+
+- Question: Should placeholder TUI surfaces such as settings and help become part of the required product surface or stay explicitly out of scope?
+- Risk: The UI appears broader than the actually finished feature set.
+- Next decision needed: Either remove or complete placeholder screens and update requirements accordingly.

+## Purpose And Scope
+
+- Project name: FFX
+- User problem: TV episode files from mixed sources arrive with inconsistent codecs, stream metadata, subtitle layouts, season and episode numbering, and output filenames, which makes them awkward to archive and use in media-player applications.
+- Target users: Individual operators curating a local TV media library on a workstation, especially users willing to define normalization rules per show.
+- Success outcome: A user can inspect source files, define reusable show and pattern rules, and produce output files whose streams, metadata, and filenames follow a predictable schema for web playback and library import.
+- Out of scope:
+  - Multi-user or hosted service workflows.
+  - General movie-library management.
+  - Distributed transcoding or remote job orchestration.
+  - Broad media-server administration beyond file preparation.
+
+## Required Product
+
+- Deliverable type: Installable Python command-line application with a Textual terminal UI for inspection and rule editing.
+- Core capabilities:
+  - Maintain an SQLite-backed database of shows, filename-matching patterns, per-pattern stream layouts and metadata tags, and optional season-shift rules.
+  - Inspect existing media files through `ffprobe` and compare discovered stream metadata with stored normalization rules.
+  - Convert media files through `ffmpeg` into a normalized output layout, including video recoding, audio transcoding to Opus, metadata cleanup and rewrite, and controlled disposition flags.
+  - Build output filenames from detected or configured show, season, and episode information, optionally enriched from TMDB and a configurable Jinja-style filename template.
+  - Support auxiliary file operations such as subtitle import, unmuxing, crop detection, and rename-only runs.
+- Supported environments:
+  - Local execution on a Python-capable workstation.
+  - Best-supported on Linux-like systems because the implementation assumes `~/.local`, `/dev/null`, `nice`, and `cpulimit`.
+  - Requires `ffmpeg`, `ffprobe`, and `cpulimit` on `PATH`.
+- Operational owner: The local user running the tool and maintaining its config, database, and external tooling.
+
+## Suggested User Stories
+
+- As a library maintainer, I want to define show-specific matching rules once so that future source files can be normalized automatically.
+- As an operator, I want to inspect a file before conversion so that I can compare its actual streams and tags against the stored target schema.
+- As a user preparing web-playback files, I want to recode video and audio with a small set of predictable options so that results are compatible and consistently named.
+- As a user dealing with nonstandard releases, I want CLI overrides for language, title, stream order, default and forced tracks, and season and episode data so that one-off fixes do not require database edits first.
+- As a user importing anime or other shifted numbering schemes, I want season and episode offsets per show so that generated filenames align with TMDB and media-library expectations.
+
+## Functional Requirements
+
+- The system shall provide a CLI entrypoint named `ffx` with commands for `convert`, `inspect`, `shows`, `unmux`, `cropdetect`, `version`, and `help`.
+- The system shall persist reusable normalization rules in SQLite for:
+  - shows and show formatting digits,
+  - regex-based filename patterns,
+  - per-pattern media tags,
+  - per-pattern stream definitions,
+  - shifted-season mappings,
+  - internal database version properties.
+- The system shall inspect source media using `ffprobe` and derive a structured description of container metadata and streams.
+- The system shall optionally open a Textual UI to browse shows, inspect files, and create, edit, or delete shows, patterns, stream definitions, tags, and shifted-season rules.
+- The system shall match filenames against stored regex patterns to decide whether an input file should inherit a target stream and metadata schema.
+- The system shall convert supported input files (`mkv`, `mp4`, `avi`, `flv`, `webm`) with `ffmpeg`, supporting at least:
+  - VP9, AV1, and H.264 video encoding,
+  - Opus audio encoding with bitrate selection based on channel layout,
+  - metadata and disposition rewriting,
+  - optional crop detection and crop application,
+  - optional deinterlacing and denoising,
+  - optional subtitle import from external files,
+  - rename-only copy mode.
+- The system shall support optional TMDB lookups to resolve show names, years, and episode titles when a show ID, season, and episode are available.
+- The system shall generate output filenames from show metadata, season and episode indices, and episode names using the configured filename template.
+- The system shall allow CLI overrides for stream languages, stream titles, default and forced tracks, stream order, TMDB show and episode data, output directory, label prefix, and processing resource limits.
+- The system shall support extracting streams into separate files via `unmux` and reporting suggested crop parameters via `cropdetect`.
+- The system shall handle invalid input and system failures gracefully by logging warnings or raising `click` errors for missing files, invalid media, missing TMDB credentials, incompatible database versions, and ambiguous track dispositions when prompting is disabled.
+
+## Quality Requirements
+
+- The system should stay understandable as a small local tool: controllers, descriptors, models, and screens should remain separate enough for contributors to trace a workflow end to end.
+- The system should produce predictable output for the same database rules, CLI overrides, and source files.
+- The system should preserve a lightweight operational footprint: local SQLite state, local log file, no mandatory background services.
+- The system should be testable through the existing combinatorial CLI-oriented test harness and through isolated logic in descriptors and controllers.
+- The system should expose enough logging to diagnose failed probes, failed conversions, and rule mismatches without requiring a debugger.
+
+## Constraints And Assumptions
+
+- Technology constraints:
+  - Python package built with setuptools.
+  - Primary libraries: `click`, `textual`, `sqlalchemy`, `jinja2`, `requests`.
+  - Conversion and inspection rely on external executables rather than pure-Python media libraries.
+- Hosting or infrastructure constraints:
+  - Intended for local execution, not server deployment.
+  - Stores default state in `~/.local/etc/ffx.json`, `~/.local/var/ffx/ffx.db`, and `~/.local/var/log/ffx.log`.
+- Timeline constraints:
+  - The current implemented scope reflects a compact alpha release stream up to version `0.2.3`.
+- Team capacity assumptions:
+  - Maintained as a small codebase where simple patterns and direct controller logic are preferred over framework-heavy abstractions.
+- Third-party dependencies:
+  - `ffmpeg`, `ffprobe`, and `cpulimit`.
+  - TMDB API access through `TMDB_API_KEY` for metadata enrichment.
+
+## Acceptance Scope
+
+- First release boundary:
+  - Local installation through `pip`.
+  - Working SQLite-backed rule storage.
+  - Functional CLI conversion and inspection workflows.
+  - Textual CRUD flows for shows, patterns, tags, tracks, and shifted seasons.
+  - TMDB-assisted filename generation, subtitle import, season shifting, database versioning, and configurable output filename templating.
+- Excluded follow-up ideas:
+  - Completing placeholder screens such as settings and help.
+  - Hardening platform portability beyond Linux-like systems.
+  - Broader media types, richer release packaging, and production-grade background processing.
+- Demonstration scenario:
+  - Inspect a TV episode file, define or update the matching show and pattern in the TUI, then run `ffx convert` so the result uses the stored stream schema, optional TMDB episode naming, and a normalized output filename.
