+# 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

+GNU General Public License
+==========================
+
+_Version 3, 29 June 2007_  
+_Copyright © 2007 Free Software Foundation, Inc. &lt;<http://fsf.org/>&gt;_
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+## Preamble
+
+The GNU General Public License is a free, copyleft license for software and other
+kinds of works.
+
+The licenses for most software and other practical works are designed to take away
+your freedom to share and change the works. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change all versions of a
+program--to make sure it remains free software for all its users. We, the Free
+Software Foundation, use the GNU General Public License for most of our software; it
+applies also to any other work released this way by its authors. You can apply it to
+your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our General
+Public Licenses are designed to make sure that you have the freedom to distribute
+copies of free software (and charge for them if you wish), that you receive source
+code or can get it if you want it, that you can change the software or use pieces of
+it in new free programs, and that you know you can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights or
+asking you to surrender the rights. Therefore, you have certain responsibilities if
+you distribute copies of the software, or if you modify it: responsibilities to
+respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or for a fee,
+you must pass on to the recipients the same freedoms that you received. You must make
+sure that they, too, receive or can get the source code. And you must show them these
+terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: **(1)** assert
+copyright on the software, and **(2)** offer you this License giving you legal permission
+to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that there is
+no warranty for this free software. For both users' and authors' sake, the GPL
+requires that modified versions be marked as changed, so that their problems will not
+be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified versions of
+the software inside them, although the manufacturer can do so. This is fundamentally
+incompatible with the aim of protecting users' freedom to change the software. The
+systematic pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we have designed
+this version of the GPL to prohibit the practice for those products. If such problems
+arise substantially in other domains, we stand ready to extend this provision to
+those domains in future versions of the GPL, as needed to protect the freedom of
+users.
+
+Finally, every program is threatened constantly by software patents. States should
+not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that patents
+applied to a free program could make it effectively proprietary. To prevent this, the
+GPL assures that patents cannot be used to render the program non-free.
+
+The precise terms and conditions for copying, distribution and modification follow.
+
+## TERMS AND CONDITIONS
+
+### 0. Definitions
+
+“This License” refers to version 3 of the GNU General Public License.
+
+“Copyright” also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+“The Program” refers to any copyrightable work licensed under this
+License. Each licensee is addressed as “you”. “Licensees” and
+“recipients” may be individuals or organizations.
+
+To “modify” a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact copy. The
+resulting work is called a “modified version” of the earlier work or a
+work “based on” the earlier work.
+
+A “covered work” means either the unmodified Program or a work based on
+the Program.
+
+To “propagate” a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for infringement under
+applicable copyright law, except executing it on a computer or modifying a private
+copy. Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as well.
+
+To “convey” a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays “Appropriate Legal Notices” to the
+extent that it includes a convenient and prominently visible feature that **(1)**
+displays an appropriate copyright notice, and **(2)** tells the user that there is no
+warranty for the work (except to the extent that warranties are provided), that
+licensees may convey the work under this License, and how to view a copy of this
+License. If the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+### 1. Source Code
+
+The “source code” for a work means the preferred form of the work for
+making modifications to it. “Object code” means any non-source form of a
+work.
+
+A “Standard Interface” means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of interfaces
+specified for a particular programming language, one that is widely used among
+developers working in that language.
+
+The “System Libraries” of an executable work include anything, other than
+the work as a whole, that **(a)** is included in the normal form of packaging a Major
+Component, but which is not part of that Major Component, and **(b)** serves only to
+enable use of the work with that Major Component, or to implement a Standard
+Interface for which an implementation is available to the public in source code form.
+A “Major Component”, in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system (if any) on which
+the executable work runs, or a compiler used to produce the work, or an object code
+interpreter used to run it.
+
+The “Corresponding Source” for a work in object code form means all the
+source code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities. However,
+it does not include the work's System Libraries, or general-purpose tools or
+generally available free programs which are used unmodified in performing those
+activities but which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for the work, and
+the source code for shared libraries and dynamically linked subprograms that the work
+is specifically designed to require, such as by intimate data communication or
+control flow between those subprograms and other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+The Corresponding Source for a work in source code form is that same work.
+
+### 2. Basic Permissions
+
+All rights granted under this License are granted for the term of copyright on the
+Program, and are irrevocable provided the stated conditions are met. This License
+explicitly affirms your unlimited permission to run the unmodified Program. The
+output from running a covered work is covered by this License only if the output,
+given its content, constitutes a covered work. This License acknowledges your rights
+of fair use or other equivalent, as provided by copyright law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey covered
+works to others for the sole purpose of having them make modifications exclusively
+for you, or provide you with facilities for running those works, provided that you
+comply with the terms of this License in conveying all material for which you do not
+control copyright. Those thus making or running the covered works for you must do so
+exclusively on your behalf, under your direction and control, on terms that prohibit
+them from making any copies of your copyrighted material outside their relationship
+with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+### 3. Protecting Users' Legal Rights From Anti-Circumvention Law
+
+No covered work shall be deemed part of an effective technological measure under any
+applicable law fulfilling obligations under article 11 of the WIPO copyright treaty
+adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention
+of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention of
+technological measures to the extent such circumvention is effected by exercising
+rights under this License with respect to the covered work, and you disclaim any
+intention to limit operation or modification of the work as a means of enforcing,
+against the work's users, your or third parties' legal rights to forbid circumvention
+of technological measures.
+
+### 4. Conveying Verbatim Copies
+
+You may convey verbatim copies of the Program's source code as you receive it, in any
+medium, provided that you conspicuously and appropriately publish on each copy an
+appropriate copyright notice; keep intact all notices stating that this License and
+any non-permissive terms added in accord with section 7 apply to the code; keep
+intact all notices of the absence of any warranty; and give all recipients a copy of
+this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you may offer
+support or warranty protection for a fee.
+
+### 5. Conveying Modified Source Versions
+
+You may convey a work based on the Program, or the modifications to produce it from
+the Program, in the form of source code under the terms of section 4, provided that
+you also meet all of these conditions:
+
+* **a)** The work must carry prominent notices stating that you modified it, and giving a
+relevant date.
+* **b)** The work must carry prominent notices stating that it is released under this
+License and any conditions added under section 7. This requirement modifies the
+requirement in section 4 to “keep intact all notices”.
+* **c)** You must license the entire work, as a whole, under this License to anyone who
+comes into possession of a copy. This License will therefore apply, along with any
+applicable section 7 additional terms, to the whole of the work, and all its parts,
+regardless of how they are packaged. This License gives no permission to license the
+work in any other way, but it does not invalidate such permission if you have
+separately received it.
+* **d)** If the work has interactive user interfaces, each must display Appropriate Legal
+Notices; however, if the Program has interactive interfaces that do not display
+Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works, which are
+not by their nature extensions of the covered work, and which are not combined with
+it such as to form a larger program, in or on a volume of a storage or distribution
+medium, is called an “aggregate” if the compilation and its resulting
+copyright are not used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work in an aggregate
+does not cause this License to apply to the other parts of the aggregate.
+
+### 6. Conveying Non-Source Forms
+
+You may convey a covered work in object code form under the terms of sections 4 and
+5, provided that you also convey the machine-readable Corresponding Source under the
+terms of this License, in one of these ways:
+
+* **a)** Convey the object code in, or embodied in, a physical product (including a
+physical distribution medium), accompanied by the Corresponding Source fixed on a
+durable physical medium customarily used for software interchange.
+* **b)** Convey the object code in, or embodied in, a physical product (including a
+physical distribution medium), accompanied by a written offer, valid for at least
+three years and valid for as long as you offer spare parts or customer support for
+that product model, to give anyone who possesses the object code either **(1)** a copy of
+the Corresponding Source for all the software in the product that is covered by this
+License, on a durable physical medium customarily used for software interchange, for
+a price no more than your reasonable cost of physically performing this conveying of
+source, or **(2)** access to copy the Corresponding Source from a network server at no
+charge.
+* **c)** Convey individual copies of the object code with a copy of the written offer to
+provide the Corresponding Source. This alternative is allowed only occasionally and
+noncommercially, and only if you received the object code with such an offer, in
+accord with subsection 6b.
+* **d)** Convey the object code by offering access from a designated place (gratis or for
+a charge), and offer equivalent access to the Corresponding Source in the same way
+through the same place at no further charge. You need not require recipients to copy
+the Corresponding Source along with the object code. If the place to copy the object
+code is a network server, the Corresponding Source may be on a different server
+(operated by you or a third party) that supports equivalent copying facilities,
+provided you maintain clear directions next to the object code saying where to find
+the Corresponding Source. Regardless of what server hosts the Corresponding Source,
+you remain obligated to ensure that it is available for as long as needed to satisfy
+these requirements.
+* **e)** Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are being
+offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from the
+Corresponding Source as a System Library, need not be included in conveying the
+object code work.
+
+A “User Product” is either **(1)** a “consumer product”, which
+means any tangible personal property which is normally used for personal, family, or
+household purposes, or **(2)** anything designed or sold for incorporation into a
+dwelling. In determining whether a product is a consumer product, doubtful cases
+shall be resolved in favor of coverage. For a particular product received by a
+particular user, “normally used” refers to a typical or common use of
+that class of product, regardless of the status of the particular user or of the way
+in which the particular user actually uses, or expects or is expected to use, the
+product. A product is a consumer product regardless of whether the product has
+substantial commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+“Installation Information” for a User Product means any methods,
+procedures, authorization keys, or other information required to install and execute
+modified versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the continued
+functioning of the modified object code is in no case prevented or interfered with
+solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically for
+use in, a User Product, and the conveying occurs as part of a transaction in which
+the right of possession and use of the User Product is transferred to the recipient
+in perpetuity or for a fixed term (regardless of how the transaction is
+characterized), the Corresponding Source conveyed under this section must be
+accompanied by the Installation Information. But this requirement does not apply if
+neither you nor any third party retains the ability to install modified object code
+on the User Product (for example, the work has been installed in ROM).
+
+The requirement to provide Installation Information does not include a requirement to
+continue to provide support service, warranty, or updates for a work that has been
+modified or installed by the recipient, or for the User Product in which it has been
+modified or installed. Access to a network may be denied when the modification itself
+materially and adversely affects the operation of the network or violates the rules
+and protocols for communication across the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord with
+this section must be in a format that is publicly documented (and with an
+implementation available to the public in source code form), and must require no
+special password or key for unpacking, reading or copying.
+
+### 7. Additional Terms
+
+“Additional permissions” are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions. Additional
+permissions that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part may be
+used separately under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when you
+modify the work.) You may place additional permissions on material, added by you to a
+covered work, for which you have or can give appropriate copyright permission.
+
+Notwithstanding any other provision of this License, for material you add to a
+covered work, you may (if authorized by the copyright holders of that material)
+supplement the terms of this License with terms:
+
+* **a)** Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+* **b)** Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed by works
+containing it; or
+* **c)** Prohibiting misrepresentation of the origin of that material, or requiring that
+modified versions of such material be marked in reasonable ways as different from the
+original version; or
+* **d)** Limiting the use for publicity purposes of names of licensors or authors of the
+material; or
+* **e)** Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+* **f)** Requiring indemnification of licensors and authors of that material by anyone
+who conveys the material (or modified versions of it) with contractual assumptions of
+liability to the recipient, for any liability that these contractual assumptions
+directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered “further
+restrictions” within the meaning of section 10. If the Program as you received
+it, or any part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term. If a
+license document contains a further restriction but permits relicensing or conveying
+under this License, you may add to a covered work material governed by the terms of
+that license document, provided that the further restriction does not survive such
+relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place, in
+the relevant source files, a statement of the additional terms that apply to those
+files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form of a
+separately written license, or stated as exceptions; the above requirements apply
+either way.
+
+### 8. Termination
+
+You may not propagate or modify a covered work except as expressly provided under
+this License. Any attempt otherwise to propagate or modify it is void, and will
+automatically terminate your rights under this License (including any patent licenses
+granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from a
+particular copyright holder is reinstated **(a)** provisionally, unless and until the
+copyright holder explicitly and finally terminates your license, and **(b)** permanently,
+if the copyright holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means, this
+is the first time you have received notice of violation of this License (for any
+work) from that copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses of
+parties who have received copies or rights from you under this License. If your
+rights have been terminated and not permanently reinstated, you do not qualify to
+receive new licenses for the same material under section 10.
+
+### 9. Acceptance Not Required for Having Copies
+
+You are not required to accept this License in order to receive or run a copy of the
+Program. Ancillary propagation of a covered work occurring solely as a consequence of
+using peer-to-peer transmission to receive a copy likewise does not require
+acceptance. However, nothing other than this License grants you permission to
+propagate or modify any covered work. These actions infringe copyright if you do not
+accept this License. Therefore, by modifying or propagating a covered work, you
+indicate your acceptance of this License to do so.
+
+### 10. Automatic Licensing of Downstream Recipients
+
+Each time you convey a covered work, the recipient automatically receives a license
+from the original licensors, to run, modify and propagate that work, subject to this
+License. You are not responsible for enforcing compliance by third parties with this
+License.
+
+An “entity transaction” is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an organization, or
+merging organizations. If propagation of a covered work results from an entity
+transaction, each party to that transaction who receives a copy of the work also
+receives whatever licenses to the work the party's predecessor in interest had or
+could give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if the predecessor
+has it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights granted or
+affirmed under this License. For example, you may not impose a license fee, royalty,
+or other charge for exercise of rights granted under this License, and you may not
+initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging
+that any patent claim is infringed by making, using, selling, offering for sale, or
+importing the Program or any portion of it.
+
+### 11. Patents
+
+A “contributor” is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The work thus
+licensed is called the contributor's “contributor version”.
+
+A contributor's “essential patent claims” are all patent claims owned or
+controlled by the contributor, whether already acquired or hereafter acquired, that
+would be infringed by some manner, permitted by this License, of making, using, or
+selling its contributor version, but do not include claims that would be infringed
+only as a consequence of further modification of the contributor version. For
+purposes of this definition, “control” includes the right to grant patent
+sublicenses in a manner consistent with the requirements of this License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent license
+under the contributor's essential patent claims, to make, use, sell, offer for sale,
+import and otherwise run, modify and propagate the contents of its contributor
+version.
+
+In the following three paragraphs, a “patent license” is any express
+agreement or commitment, however denominated, not to enforce a patent (such as an
+express permission to practice a patent or covenant not to sue for patent
+infringement). To “grant” such a patent license to a party means to make
+such an agreement or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free of charge
+and under the terms of this License, through a publicly available network server or
+other readily accessible means, then you must either **(1)** cause the Corresponding
+Source to be so available, or **(2)** arrange to deprive yourself of the benefit of the
+patent license for this particular work, or **(3)** arrange, in a manner consistent with
+the requirements of this License, to extend the patent license to downstream
+recipients. “Knowingly relying” means you have actual knowledge that, but
+for the patent license, your conveying the covered work in a country, or your
+recipient's use of the covered work in a country, would infringe one or more
+identifiable patents in that country that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement, you
+convey, or propagate by procuring conveyance of, a covered work, and grant a patent
+license to some of the parties receiving the covered work authorizing them to use,
+propagate, modify or convey a specific copy of the covered work, then the patent
+license you grant is automatically extended to all recipients of the covered work and
+works based on it.
+
+A patent license is “discriminatory” if it does not include within the
+scope of its coverage, prohibits the exercise of, or is conditioned on the
+non-exercise of one or more of the rights that are specifically granted under this
+License. You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which you make
+payment to the third party based on the extent of your activity of conveying the
+work, and under which the third party grants, to any of the parties who would receive
+the covered work from you, a discriminatory patent license **(a)** in connection with
+copies of the covered work conveyed by you (or copies made from those copies), or **(b)**
+primarily for and in connection with specific products or compilations that contain
+the covered work, unless you entered into that arrangement, or that patent license
+was granted, prior to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available to you
+under applicable patent law.
+
+### 12. No Surrender of Others' Freedom
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from the
+conditions of this License. If you cannot convey a covered work so as to satisfy
+simultaneously your obligations under this License and any other pertinent
+obligations, then as a consequence you may not convey it at all. For example, if you
+agree to terms that obligate you to collect a royalty for further conveying from
+those to whom you convey the Program, the only way you could satisfy both those terms
+and this License would be to refrain entirely from conveying the Program.
+
+### 13. Use with the GNU Affero General Public License
+
+Notwithstanding any other provision of this License, you have permission to link or
+combine any covered work with a work licensed under version 3 of the GNU Affero
+General Public License into a single combined work, and to convey the resulting work.
+The terms of this License will continue to apply to the part which is the covered
+work, but the special requirements of the GNU Affero General Public License, section
+13, concerning interaction through a network will apply to the combination as such.
+
+### 14. Revised Versions of this License
+
+The Free Software Foundation may publish revised and/or new versions of the GNU
+General Public License from time to time. Such new versions will be similar in spirit
+to the present version, but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies that
+a certain numbered version of the GNU General Public License “or any later
+version” applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published by the
+Free Software Foundation. If the Program does not specify a version number of the GNU
+General Public License, you may choose any version ever published by the Free
+Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of the GNU
+General Public License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the Program.
+
+Later license versions may give you additional or different permissions. However, no
+additional obligations are imposed on any author or copyright holder as a result of
+your choosing to follow a later version.
+
+### 15. Disclaimer of Warranty
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE
+QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
+DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+### 16. Limitation of Liability
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY
+COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS
+PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE
+OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE
+WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+### 17. Interpretation of Sections 15 and 16
+
+If the disclaimer of warranty and limitation of liability provided above cannot be
+given local legal effect according to their terms, reviewing courts shall apply local
+law that most closely approximates an absolute waiver of all civil liability in
+connection with the Program, unless a warranty or assumption of liability accompanies
+a copy of the Program in return for a fee.
+
+_END OF TERMS AND CONDITIONS_
+
+## How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible use to
+the public, the best way to achieve this is to make it free software which everyone
+can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach them
+to the start of each source file to most effectively state the exclusion of warranty;
+and each file should have at least the “copyright” line and a pointer to
+where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like this
+when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type 'show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type 'show c' for details.
+
+The hypothetical commands `show w` and `show c` should show the appropriate parts of
+the General Public License. Of course, your program's commands might be different;
+for a GUI interface, you would use an “about box”.
+
+You should also get your employer (if you work as a programmer) or school, if any, to
+sign a “copyright disclaimer” for the program, if necessary. For more
+information on this, and how to apply and follow the GNU GPL, see
+&lt;<http://www.gnu.org/licenses/>&gt;.
+
+The GNU General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may consider it
+more useful to permit linking proprietary applications with the library. If this is
+what you want to do, use the GNU Lesser General Public License instead of this
+License. But first, please read
+&lt;<http://www.gnu.org/philosophy/why-not-lgpl.html>&gt;.

+# FFX
+
+FFX is a local CLI and Textual TUI for inspecting TV episode files, storing normalization rules in SQLite, and converting outputs into a predictable stream, metadata, and filename layout.
+
+## Requirements
+
+- Linux-like environment
+- `python3`
+- `ffmpeg`
+- `ffprobe`
+- `cpulimit`
+
+## Installation
+
+FFX uses a two-step local setup flow.
+
+### 1. Install The Bundle
+
+This step creates or reuses the persistent bundle virtualenv in `~/.local/share/ffx.venv`, installs FFX into it, and ensures `ffx` is exposed through a shell alias.
+
+```sh
+bash tools/setup.sh
+```
+
+If you also want the Python packages needed for the modern test suite:
+
+```sh
+bash tools/setup.sh --with-tests
+```
+
+You can verify the bundle state without changing anything:
+
+```sh
+bash tools/setup.sh --check
+```
+
+### 2. Prepare System Dependencies And Local User Files
+
+This step installs or verifies workstation dependencies and seeds local config and data directories. It is the step wrapped by the CLI command `ffx configure_workstation`.
+
+Run it directly:
+
+```sh
+bash tools/configure_workstation.sh
+```
+
+Or through the installed CLI:
+
+```sh
+ffx configure_workstation
+```
+
+Check-only mode is available in both forms:
+
+```sh
+bash tools/configure_workstation.sh --check
+ffx configure_workstation --check
+```
+
+`tools/configure_workstation.sh` does not manage the bundle virtualenv. Python-side test packages belong to `tools/setup.sh --with-tests`.
+
+## Basic Usage
+
+Examples:
+
+```sh
+ffx version
+ffx inspect /path/to/episode.mkv
+ffx convert /path/to/episode.mkv
+ffx shows
+```
+
+## Modern Tests
+
+Install Python test packages first:
+
+```sh
+bash tools/setup.sh --with-tests
+```
+
+Then run the modern automatically discovered test suite:
+
+```sh
+./tools/test.sh
+```
+
+This runner uses `pytest` and intentionally excludes the legacy harness under `tests/legacy/`.
+
+## Default Local Paths
+
+- Config: `~/.local/etc/ffx.json`
+- Database: `~/.local/var/ffx/ffx.db`
+- Log file: `~/.local/var/log/ffx.log`
+- Bundle venv: `~/.local/share/ffx.venv`
+
+## TMDB
+
+TMDB-backed metadata enrichment requires `TMDB_API_KEY` to be set in the environment.
+
+## Version History
+
+### 0.2.6
+
+- DB-free `ffx edit` workflow for in-place metadata editing via temporary-file rewrite
+- inspect and edit workflows split into dedicated Textual screens with shared media-workflow support
+- Textual tables and row actions now separate raw data from rendered labels to avoid markup leaking into stored metadata
+- responsive screen layout pass, `Esc` back handling, sortable show/inspect tables, and improved edit-screen notifications/toggles
+- application-wide UTF-8 i18n catalogs with language precedence from CLI over config over system over German default
+- metadata normalization extended for localized subtitle titles, ISO language cleanup, and smarter track editor language/title helpers
+
+### 0.2.5
+
+- show-level quality and notes fields
+- pattern-over-show-over-default season-shift resolution with dynamic DB migration loading
+- migration prompt now reports the upgrade path and creates an in-place DB backup before applying schema changes
+- `upgrade --branch <name>` now fetches remote-only branches before switching
+- `unmux` now applies season shifting to subtitle output filenames
+- convert now keeps DB-defined target subtitle dispositions authoritative over sidecar filename disposition flags when a pattern definition exists
+- focused modern tests added around migrations, unmux, upgrade, and subtitle-disposition import precedence
+
+### 0.2.4
+
+- lightweight CLI commands now stay import-light via lazy runtime loading
+- setup/config templating moved to `assets/ffx.json.j2`
+- aligned two-step local setup wrappers: `ffx setup` and `ffx configure_workstation`
+- combined `ffprobe` payload reuse in `FileProperties`
+- configurable crop-detect sampling plus per-process crop result caching
+- single-query controller accessors and conditional DB schema bootstrap
+- shared screen bootstrap/controller wiring for large detail screens
+- configurable default season/episode digit lengths
+- digit-aware `rename` and padded `unmux` filename markers
+
+### 0.2.3
+
+- PyPI packaging
+- output filename templating
+- season shifting
+- DB versioning
+
+### 0.2.2
+
+- CLI overrides
+
+### 0.2.1
+
+- signature handling
+- tag cleanup
+- bugfixes and refactoring
+
+### 0.2.0
+
+- tests
+- config file
+
+### 0.1.3
+
+- subtitle file imports
+
+### 0.1.2
+
+- bugfixes
+
+### 0.1.1
+
+- bugfixes
+- TMDB show identification

+# Scratchpad
+
+## Goal
+
+- Capture a compact, project-wide list of optimization candidates after a broad scan of the current FFX codebase, tooling, and requirements.
+
+## Focused Snapshot
+
+- Highest-leverage application optimizations:
+  - Decide whether placeholder help/settings screens should ship or disappear.
+  - Trim dead helpers and other dormant surface that still looks active.
+
+- Highest-leverage repo and workflow optimizations:
+  - Continue migrating the oversized legacy test/combinator surface into focused modern tests so it is easier to run, debug, and extend.
+
+## Optimization Candidates
+
+1. Placeholder UI surfaces should either ship or disappear
+- [`src/ffx/help_screen.py`](/home/osgw/.local/src/codex/ffx/src/ffx/help_screen.py) and [`src/ffx/settings_screen.py`](/home/osgw/.local/src/codex/ffx/src/ffx/settings_screen.py) are placeholders.
+- Optimization:
+  - Either remove them from the active UI surface or complete them.
+  - Avoid paying ongoing maintenance cost for unfinished navigation targets.
+- Expected value:
+  - Leaner interface.
+  - Lower UX ambiguity.
+
+2. Several helper functions are unfinished or dead-weight
+- [`src/ffx/helper.py`](/home/osgw/.local/src/codex/ffx/src/ffx/helper.py) contains `permutateList(...): pass`.
+- There are many combinator and conversion placeholders across tests and migrations.
+- Optimization:
+  - Remove dead code, finish it, or isolate it behind a clearly dormant area.
+  - Avoid carrying stubbed utility surface that looks reusable but is not.
+- Expected value:
+  - Smaller mental model.
+  - Less time spent re-evaluating inactive paths.
+
+3. Test suite shape is expensive to understand and likely expensive to run
+- The project still carries a large legacy matrix of combinator files under [`tests/legacy`](/home/osgw/.local/src/codex/ffx/tests/legacy), several placeholder `pass` implementations, and at least one suspicious filename with an embedded space: [`tests/legacy/disposition_combinator_2_3 .py`](/home/osgw/.local/src/codex/ffx/tests/legacy/disposition_combinator_2_3 .py).
+- A first focused replacement slice now exists in [`tests/integration/subtrack_mapping/test_cli_bundle.py`](/home/osgw/.local/src/codex/ffx/tests/integration/subtrack_mapping/test_cli_bundle.py), so the remaining work is migration and consolidation rather than creating the modern test shape from scratch.
+- Optimization:
+  - Continue replacing broad combinator matrices with focused parametrized integration and unit tests.
+  - Retire the bespoke legacy discovery and runner path once equivalent coverage exists.
+  - Normalize file naming and test discovery conventions.
+- Expected value:
+  - Faster contributor onboarding.
+  - Easier CI adoption later.
+
+## Open
+
+- Durable shipped items have been moved into [`README.md`](/home/osgw/.local/src/codex/ffx/README.md) version history through `0.2.6`.
+- Should optimization work focus first on operator-perceived latency, internal maintainability, or correctness-risk cleanup that also has performance upside?
+- Is the long-term supported model still “local Linux workstation plus Textual UI,” or should optimization decisions bias toward a more scriptable/headless CLI?
+
+## Gaps Right Now
+
+- No explicit prioritization owner or milestone for the optimization backlog.
+- No benchmark or timing harness exists for startup, probe, DB, or conversion orchestration overhead.
+- Repo hygiene is still mixed with generated artifacts and some clearly unfinished files.
+- The legacy TMDB-backed `Scenario 4` path is currently blocked by a pattern/track regression: `Patterns must define at least one track before they can be stored.` This surfaced while rerunning TMDB-dependent checks after the zero-track pattern hardening.
+
+## Next
+
+1. Triage the list into quick wins, medium refactors, and long-horizon cleanup.
+2. Tackle the cheapest remaining product-surface cleanup first:
+   - placeholder UI surfaces and dead helper cleanup.
+3. Continue replacing oversized legacy test matrices with focused modern integration and unit coverage.
+4. Triage the legacy `Scenario 4` pattern/track failure and decide whether to fix the harness, adapt it to the zero-track guard, or retire that path during the ongoing test-suite migration.
+
+## Delete When
+
+- Delete this scratchpad once the optimization backlog is either converted into issues/work items or distilled into durable project guidance.

+# Preparation Script Design
+
+Rule set name: `preparation-script-design`
+
+Rule set ID: `PSD`
+
+Status: optional, prompt-activated only
+
+Trigger examples:
+
+- `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/cli.py`](/home/osgw/.local/src/codex/ffx/src/ffx/cli.py), exposed as the `ffx` command and via `python -m ffx`, including lightweight maintenance wrappers for bundle setup, workstation preparation, and upgrade tasks.
+  - 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.
+  - File inspection caches combined `ffprobe` data and crop-detection results per source and sampling window within one process to avoid repeated subprocess work.
+- Storage:
+  - SQLite via SQLAlchemy ORM, with schema rooted in shows, patterns, tracks, media tags, track tags, shifted seasons, and generic properties.
+  - Ordered schema migrations are loaded dynamically from per-version-step modules under [`src/ffx/model/migration/`](/home/osgw/.local/src/codex/ffx/src/ffx/model/migration/).
+  - A configuration JSON file supplies optional path, metadata-filtering, and filename-template settings.
+- Integration adapters:
+  - Process execution wrapper for `ffmpeg`, `ffprobe`, `nice`, and `cpulimit`, with explicit disabled states for niceness and CPU limiting, support for both absolute `cpulimit` values and machine-wide percent input, and a combined `cpulimit -- nice -n ... <command>` execution shape when both limits are configured.
+  - HTTP adapter for TMDB via `requests`.
+
+## Data And Interface Notes
+
+- Key entities or records:
+  - `Show`: canonical TV show metadata plus digit-formatting rules, optional show-level notes, and an optional show-level encoding-quality fallback.
+  - `Pattern`: regex rule tying filenames to one show and one target media schema.
+  - `Track` and `TrackTag`: persisted target stream records, codec, dispositions, audio layout, and stream-level tags. Detailed source-to-target mapping rules live in `requirements/subtrack_mapping.md`.
+  - `MediaTag`: persisted container-level metadata for a pattern.
+  - `ShiftedSeason`: mapping from source numbering ranges to adjusted season and episode numbers, owned either by a show as fallback or by a pattern as override.
+  - `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 either match the runtime-required version already or have a supported sequential migration path to it.
+  - A normalized descriptor may have at most one default and one forced stream per relevant track type.
+  - Shifted-season ranges are intended not to overlap within the same owner scope and season, and runtime resolution prefers pattern-owned matches over show-owned matches.
+  - 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.

+# Metadata Editor
+
+This file defines the requirements for a database-free interactive metadata
+editor command derived from the current file-inspection UI.
+
+Feasibility from the current codebase: yes, with a moderate refactor.
+
+The strongest reusable pieces already exist:
+
+- `ffprobe`-backed media probing through `FileProperties` and `MediaDescriptor`
+- descriptor-level metadata and disposition mutation through `MediaDescriptor`
+  and `TrackDescriptor`
+- diff and ffmpeg token generation through `MediaDescriptorChangeSet`
+- stream-copy remux execution through `FfxController` with `VideoEncoder.COPY`
+- reusable tag and track edit dialogs in the Textual UI
+
+The main missing pieces are:
+
+- a CLI bootstrap path that does not initialize SQLite
+- a probe-only path that does not instantiate database-backed controllers
+- a clean separation between original file state and editable draft state
+- a safe temporary-output and replace workflow for writing changes back to the
+  same file path
+
+## Scope
+
+- One new command: `ffx edit <file>`
+- One-file interactive editing through a Textual screen derived from
+  `MediaDetailsScreen`
+- Editing container-level metadata and per-stream metadata already visible in
+  the application
+- Editing stream dispositions that are represented as metadata-like output
+  state, especially `default` and `forced`
+- Writing the result back to the original file path through a temporary output
+  file and replace step
+
+## Out Of Scope
+
+- SQLite reads, writes, migrations, or pattern matching
+- TMDB lookups, show selection, pattern selection, or shifted-season logic
+- Batch editing multiple files in one command invocation
+- Video or audio transcoding
+- Container changes, filename changes, or rename workflows
+- Stream add, stream delete, stream reorder, or stream substitution from
+  external files in the first release
+- Editing technical stream identity such as codec, stream type, source index,
+  or audio layout in the first release
+- Chapter editing
+
+## Terms
+
+- `baseline descriptor`: immutable in-memory representation of the file as last
+  probed from disk
+- `draft descriptor`: mutable in-memory representation of the desired output
+  state
+- `edit mode`: the database-free TUI mode used by `ffx edit`
+- `planned changes`: user-visible summary of the differences between baseline
+  and draft plus any configured cleanup actions
+- `temporary output file`: the write target used before replacing the original
+  file path
+
+## Rules
+
+- `METADATA_EDITOR-0001`: The system shall provide a command `ffx edit <file>`
+  that requires exactly one existing media file path and opens an interactive
+  Textual editor for that file.
+- `METADATA_EDITOR-0002`: `ffx edit` shall not initialize SQLite, shall not
+  open the configured database file, shall not prompt for database migration,
+  and shall not instantiate any controller that depends on `context['database']`.
+- `METADATA_EDITOR-0003`: `ffx edit` may still read configuration and logging
+  settings from `~/.local/etc/ffx.json`, but any global database option shall
+  have no effect on this command's behavior.
+- `METADATA_EDITOR-0004`: Edit mode shall be derived from the current
+  `MediaDetailsScreen` behavior and layout where practical, but all DB-only UI
+  elements and actions such as show selection, pattern input, and pattern CRUD
+  actions shall be hidden, disabled, or replaced.
+- `METADATA_EDITOR-0005`: Edit mode shall keep the baseline descriptor and the
+  draft descriptor as separate objects. Editing actions shall mutate only the
+  draft descriptor until the operator explicitly applies changes.
+- `METADATA_EDITOR-0006`: The application shall keep raw metadata values
+  separate from rendered labels. Rich or Textual markup may be used for
+  presentation, but it shall never be stored in descriptor state, reused as
+  source data, or written into the media file.
+- `METADATA_EDITOR-0007`: The planned-changes view shall compare the baseline
+  descriptor with the draft descriptor using `MediaDescriptorChangeSet` or an
+  equivalent descriptor-diff mechanism. It shall no longer mean `file -> db`.
+- `METADATA_EDITOR-0008`: The editor shall support container-tag add, edit, and
+  delete operations on the draft descriptor.
+- `METADATA_EDITOR-0009`: The editor shall support per-stream metadata edit
+  operations on the draft descriptor, including at least language, title, and
+  arbitrary stream tag key-value pairs.
+- `METADATA_EDITOR-0010`: The editor shall support setting and clearing
+  `default` and `forced` dispositions in the draft descriptor, while enforcing
+  that there is at most one `default` and at most one `forced` stream per track
+  type.
+- `METADATA_EDITOR-0011`: The first released editor scope shall treat technical
+  stream structure as immutable. A user shall not be able to change stream
+  count, output order, codec, track type, audio layout, or source-index
+  mapping through `ffx edit`.
+- `METADATA_EDITOR-0012`: The track-edit UI used in edit mode shall therefore
+  expose only metadata fields and supported disposition fields. Structural
+  fields that are editable in pattern-authoring workflows shall be read-only or
+  absent in edit mode.
+- `METADATA_EDITOR-0013`: The command shall write changes through an ffmpeg
+  stream-copy remux workflow only. No transcoding shall be performed as part of
+  `ffx edit`.
+- `METADATA_EDITOR-0014`: Because ffmpeg cannot rewrite the source file in
+  place, `ffx edit` shall write to a temporary output file on the same
+  filesystem as the source file and shall replace the original path only after
+  ffmpeg reports success.
+- `METADATA_EDITOR-0015`: The temporary output path shall preserve the original
+  container type and file extension. The feature shall not silently change the
+  container or extension during a metadata-only edit.
+- `METADATA_EDITOR-0016`: If the rewrite step fails, the original file shall
+  remain untouched. The system shall not leave the user with a partially
+  replaced source file.
+- `METADATA_EDITOR-0017`: After a successful replace, the application shall
+  reprobe the rewritten file, refresh the baseline descriptor from disk, reset
+  the draft state to that fresh baseline, and clear the dirty state.
+- `METADATA_EDITOR-0018`: Edit mode shall track whether unsaved draft changes
+  exist and shall require confirmation before dismissing the screen or quitting
+  the app when such changes would be lost.
+- `METADATA_EDITOR-0019`: Edit mode shall not inject conversion-only encoding
+  metadata such as encoder quality or preset markers.
+- `METADATA_EDITOR-0020`: Signature-tag behavior shall be explicit for
+  metadata-only editing. The default behavior shall not add a misleading
+  recoding-style signature to a file that was only remuxed for metadata
+  updates.
+- `METADATA_EDITOR-0021`: Configured metadata-removal rules from the local
+  configuration shall be surfaced clearly in the UI and in the planned-changes
+  view. If those rules are applied during save, the operator shall be able to
+  tell that the file will be cleaned in addition to any manual edits.
+- `METADATA_EDITOR-0022`: The command shall provide an invocation-level way to
+  disable config-driven cleanup when the operator wants a pure manual metadata
+  edit without automatic tag removal.
+- `METADATA_EDITOR-0023`: The existing global `--dry-run` behavior shall apply
+  to `ffx edit`. In dry-run mode the command shall not replace the original
+  file and shall expose the planned write operation clearly enough for the user
+  to understand what would happen.
+
+## Acceptance
+
+- `ffx edit /path/to/file.mkv` opens successfully on a workstation where the
+  configured database is missing, empty, incompatible, or intentionally
+  inaccessible.
+- Opening a file in edit mode does not trigger database bootstrap or migration
+  prompts.
+- A user can change a container tag, save, and see the rewritten file at the
+  same path with the updated metadata.
+- A user can change a stream title or language, save, and see the rewritten
+  file at the same path with the updated stream metadata.
+- A user can change `default` or `forced` on a track, save, and see the
+  rewritten file at the same path with the updated dispositions.
+- The planned-changes view reflects manual edits relative to the original file
+  and, when enabled, any configured cleanup removals.
+- No rendered Rich or Textual color markup appears in the saved file metadata.
+- If ffmpeg fails while saving, the original file remains present and readable
+  at the original path.
+- In dry-run mode, the original file remains untouched.
+
+## Current Code Fit
+
+- Good fit:
+  - `FfxController.runJob(...)` already has a `VideoEncoder.COPY` path that
+    can remux streams and apply metadata and disposition tokens.
+  - `MediaDescriptorChangeSet` already computes container-tag, stream-tag, and
+    disposition differences and can generate ffmpeg metadata tokens.
+  - `TagDetailsScreen` and `TrackDetailsScreen` already provide reusable edit
+    dialogs for draft state.
+  - `PatternDetailsScreen` already demonstrates add, edit, and delete flows for
+    tags and tracks in a draft-first UI.
+- Refactor required:
+  - `ffx` CLI initialization currently creates a database context for all
+    non-lightweight commands, so `edit` needs its own DB-free bootstrap path.
+  - `FileProperties` currently instantiates `PatternController` eagerly, so
+    probing must be split from pattern matching or made lazy.
+  - `MediaDetailsScreen` currently assumes `command == 'inspect'` and mixes
+    file state with database-backed target-pattern state.
+  - `MediaDetailsScreen` currently mutates the probed source descriptor
+    directly. Edit mode needs an immutable baseline descriptor and a separate
+    mutable draft descriptor.
+  - `TrackDetailsScreen` currently exposes structural fields that are valid for
+    pattern authoring but too dangerous for metadata-only file editing.
+
+## Risks
+
+- Container-level metadata support differs across formats, so some requested tag
+  changes may not round-trip identically through ffmpeg for every supported
+  container.
+- The existing metadata-removal implementation is conversion-oriented and may
+  remove tags more aggressively than a user expects from a manual editor unless
+  cleanup policy is made explicit.
+- The current codebase lacks a dedicated descriptor clone API, so draft-state
+  separation should be implemented deliberately instead of via accidental shared
+  references.
+- Replacing a file path with a temporary output changes inode identity, so any
+  future requirement around preserving timestamps, hard links, or extended
+  attributes would need additional explicit handling.

+# Pattern Management
+
+This file defines the behavioral contract for managing shows, patterns, and
+pattern-backed filename matching.
+
+Primary source: actual tool code in `src/ffx/`.
+Secondary source: operator intent captured in task discussion.
+
+## Scope
+
+- The show, pattern, and track hierarchy stored in SQLite.
+- The role of a pattern as a reusable normalization definition for related media files.
+- Filename-driven assignment of a scanned media file to one show through one matching pattern.
+- Duplicate-match handling when more than one pattern matches the same filename.
+
+## Terms
+
+- `show`: logical series identity such as one TV show entry in the database.
+- `pattern`: regex-backed normalization definition attached to one show.
+- `track`: one persisted target-track definition attached to one pattern.
+- `scanned media file`: one source file currently being inspected or converted.
+- `duplicate pattern match`: a filename state where more than one stored pattern matches the same scanned media file.
+- `pattern-backed target schema`: the combination of one pattern's stored media tags and stored track definitions.
+
+## Rules
+
+- `PATTERN_MANAGEMENT-0001`: The domain model shall treat a show as the parent entity for patterns that describe distinct release families or normalization schemas for that show. A show may temporarily exist without patterns during editing or initial TUI creation.
+- `PATTERN_MANAGEMENT-0002`: Each persisted pattern shall belong to exactly one show.
+- `PATTERN_MANAGEMENT-0003`: The domain model shall treat a pattern as the reusable normalization definition for a series of media files expected to share the same internal track layout and materially similar stream and container metadata.
+- `PATTERN_MANAGEMENT-0004`: Each persisted track definition shall belong to exactly one pattern.
+- `PATTERN_MANAGEMENT-0005`: A pattern may also carry pattern-level media tags. The pattern's media tags plus its track definitions together form the pattern-backed target schema.
+- `PATTERN_MANAGEMENT-0006`: A scanned media file shall resolve to at most one pattern and therefore at most one show.
+- `PATTERN_MANAGEMENT-0007`: If no pattern matches a filename, the file shall remain unmatched rather than being assigned implicitly.
+- `PATTERN_MANAGEMENT-0008`: If more than one pattern matches the same filename, the system shall raise a duplicate pattern match error instead of silently selecting one.
+- `PATTERN_MANAGEMENT-0009`: Duplicate-match detection shall apply regardless of whether the competing patterns belong to the same show or to different shows.
+- `PATTERN_MANAGEMENT-0010`: Exact duplicate pattern definitions for the same show should not create multiple persisted pattern rows.
+- `PATTERN_MANAGEMENT-0011`: A persisted pattern shall define one or more tracks. Creating or retaining a zero-track pattern in the database is invalid managed state and shall be prohibited.
+- `PATTERN_MANAGEMENT-0012`: A show may exist without patterns as an intermediate editing state, for example when a user creates the show first in the TUI and adds patterns later.
+- `PATTERN_MANAGEMENT-0013`: Operator-facing pattern management should expose the owning show, regex pattern, stored track set, and stored media-tag set so a user can reason about matching and normalization behavior.
+- `PATTERN_MANAGEMENT-0014`: Matching semantics shall be deterministic and documented. Implicit "last matching pattern wins" behavior is not acceptable released behavior.
+
+## Acceptance
+
+- A filename that matches exactly one pattern yields one matched pattern and one show identity.
+- A filename that matches no pattern yields no matched pattern and an unmatched state.
+- A filename that matches more than one pattern yields an explicit duplicate-match error.
+- A pattern-backed target schema can be reconstructed from one pattern's stored media tags and stored track definitions.
+- A show may be stored before any patterns are attached to it.
+- A pattern cannot be stored or retained as a valid managed pattern unless at least one track is defined for it.
+- Pattern-backed conversion never proceeds with two competing matching patterns for the same input filename.
+
+## Current Code Fit
+
+- `src/ffx/model/show.py` implements a one-to-many `Show -> Pattern` relationship.
+- `src/ffx/model/pattern.py` implements `Pattern.show_id`, a one-to-many `Pattern -> Track` relationship, a one-to-many `Pattern -> MediaTag` relationship, and a unique `(show_id, pattern)` constraint for freshly created databases.
+- `src/ffx/model/track.py` implements `Track.pattern_id`, so each persisted track belongs to one pattern.
+- `src/ffx/model/pattern.py` reconstructs a pattern-backed target schema through `Pattern.getMediaDescriptor(...)`, combining stored media tags and stored tracks.
+- `src/ffx/file_properties.py` assumes a scanned file resolves to at most one pattern, because it stores only one `self.__pattern` and derives one `show_id` from it.
+- `src/ffx/pattern_controller.py` prevents exact duplicate `(show_id, pattern)` definitions during create and update flows, and it refreshes cached compiled regexes when stored pattern expressions change.
+- `src/ffx/pattern_controller.py` now complies with duplicate-match safety. `matchFilename(...)` scans deterministically, returns exactly one match, returns `{}` for no match, and raises an explicit duplicate-pattern-match error when more than one pattern matches the same filename.
+- The current persistence layer already aligns with the intended empty-show workflow because a show can exist without patterns.
+- New pattern creation and schema replacement flows now require at least one track, and `TrackController.deleteTrack(...)` prevents deleting the last persisted track from a pattern.
+- Trackless legacy rows can still exist in preexisting databases, but matching now rejects them explicitly instead of letting them participate silently.
+
+## Risks
+
+- The intended "release family" meaning of a pattern is a domain assumption, not something the code verifies automatically across all files matching that pattern.
+- Preexisting databases created before the newer validation rules may still contain invalid rows, so upgrade and cleanup paths should continue to treat explicit validation failures as recoverable operator signals.

+## 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, rename-only conversion runs, and direct in-place episode renaming.
+- 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 at the show level with optional pattern-specific overrides 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`, `rename`, `unmux`, `cropdetect`, `setup`, `configure_workstation`, `upgrade`, `version`, and `help`.
+- The system shall support a two-step local installation and preparation flow:
+  - `tools/setup.sh` is the bootstrap entrypoint for the first step and shall own bundle virtualenv creation, package installation, shell alias exposure, and optional Python test-package installation.
+  - `tools/configure_workstation.sh` is the bootstrap entrypoint for the second step and shall own workstation dependency checks and installation plus local config and directory seeding.
+  - After the bundle is installed, `ffx setup` and `ffx configure_workstation` shall remain aligned wrapper entrypoints for those same two steps.
+- The CLI command `ffx setup` shall act as a wrapper for the first-step bundle-preparation flow in `tools/setup.sh`.
+- The CLI command `ffx configure_workstation` shall act as a wrapper for the second-step preparation flow in `tools/configure_workstation.sh`.
+- The system shall persist reusable normalization rules in SQLite for:
+  - shows and show formatting digits,
+  - optional show-level notes,
+  - optional show-level quality defaults,
+  - regex-based filename patterns,
+  - per-pattern media tags,
+  - per-pattern stream definitions,
+  - show-level and pattern-level shifted-season mappings,
+  - internal database version properties.
+- The system shall apply supported ordered database migrations automatically when opening an older local database file and shall fail fast when no supported path exists.
+- Before applying a required database migration, the system shall show the current version, target version, required sequential steps, and whether each corresponding migration module is present, then require user confirmation.
+- Before applying a confirmed file-backed database migration, the system shall create an in-place backup copy whose filename includes the covered version range.
+- Detailed show, pattern, and duplicate-match management rules live in `requirements/pattern_management.md`.
+- 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 move 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 resolve encoding quality by precedence `CLI override -> pattern -> show -> encoder default` and shall report the chosen value and source.
+- The system shall resolve season shifting by precedence `pattern -> show -> identity default` and shall report the chosen mapping and source.
+- Processing resource limit rules:
+  - `--nice` shall accept niceness values from `-20` through `19`; omitting the option shall disable niceness adjustment.
+  - `--cpu` shall accept either a positive absolute `cpulimit` value such as `200`, or a percentage suffixed with `%` such as `25%` to represent a share of present CPUs; omitting the option or using `0` shall disable CPU limiting.
+  - When both limits are configured, the process wrapper shall execute the target command through `cpulimit` around a `nice -n ...` invocation so both limits apply to the launched media command.
+- The system shall support extracting streams into separate files via `unmux` and reporting suggested crop parameters via `cropdetect`.
+- The system shall support in-place episode renaming via `rename`, requiring a `--prefix`, accepting optional `--season` and `--suffix` overrides, preserving the source extension, and supporting dry-run output without moving files.
+- Crop detection shall use a configurable sampling window, defaulting to a 60-second seek and a 180-second analysis duration, and repeated crop-detection requests for the same source plus sampling window shall reuse cached results within one process.
+- 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 modern automatically discovered tests and through remaining legacy harness coverage during migration.
+- 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 `0.2.6`.
+- 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.
+- Installation assumptions:
+  - The Python-side bundle install step and optional Python test extras are managed by `tools/setup.sh`, with `ffx setup` as the aligned wrapper after bootstrap.
+  - The workstation-preparation step is managed separately by `tools/configure_workstation.sh` or `ffx configure_workstation`.
+
+## 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.

+# Numbering Mapping Handling
+
+This file defines the behavioral contract for mapping source season and episode
+numbering to target season and episode numbering through stored shifted-season
+rules.
+
+Primary sources:
+- `requirements/project.md`
+- `requirements/architecture.md`
+- actual tool code in `src/ffx/`
+
+Secondary source:
+- `SCRATCHPAD.md`, used only to clarify current hardening gaps and not as the
+  primary contract source.
+
+## Scope
+
+- Persisting shifted-season rules in SQLite.
+- Allowing shifted-season rules to be attached either to a show or to a
+  specific pattern.
+- Selecting at most one active shifted-season rule for one concrete source
+  season and episode tuple.
+- Applying additive season and episode offsets to produce target numbering.
+- Using shifted target numbering during `convert` for TMDB episode lookup and
+  generated season and episode filename tokens.
+- Managing show-level default mappings and pattern-level override mappings from
+  the Textual editing workflows.
+
+## Out Of Scope
+
+- General filename parsing rules for detecting season and episode values.
+- Standalone `rename` command behavior, which currently uses explicit rename
+  inputs rather than stored shifted-season rules.
+- Stream or track mapping behavior unrelated to season and episode numbering.
+
+## Terms
+
+- `shifted-season rule`: one persisted row describing how one source-numbering
+  range maps to target numbering through additive offsets.
+- `show-level shifted-season rule`: a rule attached directly to a show and used
+  as the fallback mapping layer for that show.
+- `pattern-level shifted-season rule`: a rule attached directly to a pattern and
+  used as the override mapping layer for that pattern.
+- `source numbering`: the season and episode values detected from the current
+  source file or supplied as source-side conversion inputs before shifting.
+- `target numbering`: the season and episode values after one active
+  shifted-season rule has been applied.
+- `original season`: the source-domain season number a shifted-season rule is
+  eligible to match.
+- `episode range`: the optional source-domain episode interval covered by one
+  shifted-season rule.
+- `open bound`: an unbounded start or end of the episode range. Current storage
+  uses `-1` as the internal sentinel for an open bound.
+- `active shifted-season rule`: the single rule selected for one concrete input
+  after precedence resolution.
+- `identity mapping`: the default `1:1` outcome where source numbering is used
+  unchanged.
+
+## Rules
+
+- `SHIFTED_SEASONS_HANDLING-0001`: The domain model shall allow a
+  shifted-season rule to be owned by exactly one of:
+  - one show
+  - one pattern
+- `SHIFTED_SEASONS_HANDLING-0002`: A single shifted-season rule shall not
+  belong to both a show and a pattern at the same time.
+- `SHIFTED_SEASONS_HANDLING-0003`: A shifted-season rule shall carry these
+  fields: `original_season`, `first_episode`, `last_episode`,
+  `season_offset`, and `episode_offset`.
+- `SHIFTED_SEASONS_HANDLING-0004`: `season_offset` and `episode_offset` shall
+  be additive signed integers applied to matched source numbering to produce
+  target numbering.
+- `SHIFTED_SEASONS_HANDLING-0005`: A shifted-season rule shall match a source
+  tuple only when:
+  - the source season equals `original_season`
+  - the source episode is greater than or equal to `first_episode` when the
+    lower bound is closed
+  - the source episode is less than or equal to `last_episode` when the upper
+    bound is closed
+- `SHIFTED_SEASONS_HANDLING-0006`: An open lower or upper episode bound shall
+  represent an unbounded side of the covered source episode range.
+- `SHIFTED_SEASONS_HANDLING-0007`: If one shifted-season rule matches, target
+  numbering shall be:
+  - `target season = source season + season_offset`
+  - `target episode = source episode + episode_offset`
+- `SHIFTED_SEASONS_HANDLING-0008`: If no shifted-season rule matches, source
+  numbering shall pass through unchanged.
+- `SHIFTED_SEASONS_HANDLING-0009`: Shifted-season handling shall operate in a
+  source-to-target numbering model. Stored rules map detected source numbering
+  to the target numbering used by conversion-facing metadata and output naming.
+- `SHIFTED_SEASONS_HANDLING-0010`: Pattern matching identifies the owning show
+  and optionally a more specific owning pattern. Resolution of the active
+  shifted-season rule shall use this precedence order:
+  - matching pattern-level rule
+  - matching show-level rule
+  - identity mapping
+- `SHIFTED_SEASONS_HANDLING-0011`: At most one shifted-season rule may be
+  active for one concrete source season and episode tuple. Shifted-season rules
+  shall never stack or compose.
+- `SHIFTED_SEASONS_HANDLING-0012`: Within one owner scope, shifted-season rules
+  shall not overlap in their effective episode coverage for the same
+  `original_season`.
+- `SHIFTED_SEASONS_HANDLING-0013`: If a shifted-season rule uses two closed
+  episode bounds, `last_episode` shall be greater than or equal to
+  `first_episode`.
+- `SHIFTED_SEASONS_HANDLING-0014`: Shifted-season rule evaluation shall be
+  deterministic. Released behavior shall not depend on arbitrary database row
+  order when invalid overlapping rules exist.
+- `SHIFTED_SEASONS_HANDLING-0015`: A pattern-level rule is permitted to map to
+  zero offsets. Such a rule is a valid explicit override that beats show-level
+  fallback and produces identity mapping for its covered source range.
+- `SHIFTED_SEASONS_HANDLING-0016`: During `convert`, when show, season, and
+  episode values are available and stored shifting is active, the shifted target
+  numbering shall drive:
+  - TMDB episode lookup
+  - season and episode filename tokens such as `S01E02`
+  - generated episode basenames that include season and episode numbering
+- `SHIFTED_SEASONS_HANDLING-0017`: When conversion is supplied explicit
+  target-domain season or episode values for TMDB naming, the system shall not
+  apply stored shifting on top of those already-targeted values.
+- `SHIFTED_SEASONS_HANDLING-0018`: Operator-facing editing shall expose
+  shifted-season rule management in both of these places:
+  - show editing for show-level default mappings
+  - pattern editing for pattern-level override mappings
+- `SHIFTED_SEASONS_HANDLING-0019`: User-facing shifted-season editing should
+  present open episode bounds as a natural empty-state input rather than forcing
+  operators to type the internal sentinel directly.
+
+## Acceptance
+
+- A show can exist with zero or more show-level shifted-season rules.
+- A pattern can exist with zero or more pattern-level shifted-season rules.
+- A shifted-season rule is stored against exactly one owner scope.
+- A source tuple matching a pattern-level rule yields target numbering from that
+  rule even when a matching show-level rule also exists.
+- A source tuple matching no pattern-level rule but matching a show-level rule
+  yields target numbering from the show-level rule.
+- A source tuple matching neither scope yields identity mapping.
+- A pattern-level zero-offset rule can explicitly override a nonzero show-level
+  rule for the same covered source range.
+- Two shifted-season rules for the same owner scope and original season cannot
+  both be valid if they cover overlapping episode ranges.
+- During `convert`, shifted numbering is what TMDB episode lookup and generated
+  season and episode tokens see when stored shifting is active.
+- The TUI can display and maintain shifted-season rules from both the show and
+  pattern editing flows.
+
+## Current Code Fit
+
+- `src/ffx/model/show.py` and `src/ffx/model/pattern.py` now both expose
+  shifted-season relationships, and `src/ffx/model/shifted_season.py` stores
+  each rule against exactly one owner scope through `show_id` or `pattern_id`.
+- `src/ffx/shifted_season_controller.py` now resolves mappings with
+  pattern-over-show precedence and applies at most one active rule for a source
+  tuple.
+- `src/ffx/show_details_screen.py`,
+  `src/ffx/shifted_season_details_screen.py`, and
+  `src/ffx/shifted_season_delete_screen.py` provide reusable shifted-season
+  editing dialogs, and `src/ffx/pattern_details_screen.py` now exposes the
+  pattern-level override flow.
+- `src/ffx/cli.py` now resolves shifted numbering during `convert` from:
+  pattern-level match, then show-level match, then identity mapping.
+- `src/ffx/database.py` now migrates version-2 databases to version 3 by
+  preserving existing show-level rows and extending the schema for pattern-level
+  ownership.
+
+## Risks
+
+- The current CLI groups `--show`, `--season`, and `--episode` under one
+  override bucket used for TMDB-related behavior. Source-domain versus
+  target-domain semantics of each override must stay documented clearly so
+  stored shifting is neither skipped nor double-applied unexpectedly.
+- Existing version-2 databases only contain show-owned shifted-season rows, so a
+  version-3 migration must preserve those rows as the show-level fallback layer.
+- Current modern automated test coverage for shifted-season behavior is light,
+  so precedence, migration, and convert-time numbering behavior need focused
+  tests.

+# Subtrack Mapping
+
+This file defines the behavioral contract for mapping input subtracks to output
+subtracks during conversion.
+
+Primary source: actual tool code in `src/ffx/`.
+Secondary source: `tests/legacy/`, used only to clarify intent and reveal gaps.
+
+## Scope
+
+- Ensuring each target subtrack is created from the corresponding source-subtrack information, including stream-level metadata.
+- Mapping input streams to output streams during conversion.
+- Using persisted pattern-track definitions from the database as the target schema.
+- Allowing omission and reordering of retained tracks.
+- Keeping stream-level metadata attached to the correct source-derived logical track after remapping.
+- Normalizing target output into ordered track groups: video, audio, subtitle, then special types such as fonts or images.
+
+## Terms
+
+- `source_index`: identity of the originating input stream from ffprobe or an imported source descriptor.
+- `index`: final output-track order across all retained tracks.
+- `sub_index`: per-type position within the retained tracks of one type, for example audio stream `0` or subtitle stream `1`.
+- `target schema`: stored or constructed output-track definition that decides which tracks are kept, omitted, reordered, and rewritten.
+- `separate source file`: additional file bound to one target track slot whose media payload replaces the regular source payload for that slot.
+
+## Rules
+
+- `SUBTRACK_MAPPING-0001`: The system shall represent source-stream identity separately from output order. `source_index`, `index`, and `sub_index` are distinct concepts and shall not be collapsed into one field.
+- `SUBTRACK_MAPPING-0002`: The system shall derive `source_index` for probed tracks from the original ffprobe stream index and preserve that identity through conversion planning.
+- `SUBTRACK_MAPPING-0003`: Pattern-backed track definitions stored in the database shall persist both target output order and originating source-stream identity.
+- `SUBTRACK_MAPPING-0004`: When a filename matches a pattern, the pattern target schema shall be the source of truth for which source tracks are retained, which are omitted, and in what order retained tracks appear in the output.
+- `SUBTRACK_MAPPING-0005`: A target track may refer only to an existing source track of the same type. Conversion shall fail fast when a target track refers to a nonexistent source stream or a source stream of a different type.
+- `SUBTRACK_MAPPING-0006`: The ffmpeg mapping phase shall be generated from target output order while resolving each retained output track back to its originating source stream via `source_index`.
+- `SUBTRACK_MAPPING-0007`: Reordering and omission shall preserve logical track identity. Stream-level metadata, titles, languages, and disposition decisions shall stay attached to the correct source-derived logical track after mapping.
+- `SUBTRACK_MAPPING-0008`: The system shall support one-off CLI stream-order overrides without requiring prior database edits.
+- `SUBTRACK_MAPPING-0009`: Operator-facing inspection and editing surfaces shall expose enough source-versus-target information to let a user reason about subtrack mapping decisions.
+- `SUBTRACK_MAPPING-0010`: Test coverage for subtrack mapping shall assert source-derived identity, omission, and output order explicitly. Final track counts or final type sequences alone are insufficient proof of correct mapping.
+- `SUBTRACK_MAPPING-0011`: Retained target tracks shall appear in ordered groups: video track or tracks first, then audio tracks, then subtitle tracks, then special types such as fonts or images. Within each group, the target schema shall define the order.
+- `SUBTRACK_MAPPING-0012`: Track omission is valid when required by output compatibility, when needed to normalize source tracks into the required target group order and schema, or when explicitly requested by database rules or CLI options.
+- `SUBTRACK_MAPPING-0013`: If source tracks do not already comply with the required target group order, conversion shall reorder retained tracks to match the target ordering contract without losing source-track identity or stream-level metadata lineage.
+
+## Separate Additional Source Files
+
+- `SUBTRACK_MAPPING-0014`: A separate source file may substitute the media payload of one target subtrack without changing that target track's intended output position.
+- `SUBTRACK_MAPPING-0015`: When a separate source file is used, the target track shall remain bound to the corresponding logical source track for mapping, validation, and metadata lineage.
+- `SUBTRACK_MAPPING-0016`: Metadata for a substituted target track shall be merged from the regular source track and the separate source file when available.
+- `SUBTRACK_MAPPING-0017`: If the separate source file provides a metadata field that is also present on the regular source track, the separate source file value shall win in the target output.
+- `SUBTRACK_MAPPING-0018`: If a metadata field is absent from the separate source file, the system shall fall back to the corresponding metadata from the regular source track or target schema rewrite rules.
+
+## Acceptance
+
+- Given a source media descriptor and a pattern-backed target schema, the planned output tracks can be listed in final output order and each retained track can still be traced to one originating source stream.
+- Planned output order follows grouped target order: video, audio, subtitle, then special types.
+- Tracks not referenced by the target schema are omitted from output mapping.
+- Tracks may also be omitted when they are incompatible with the chosen output format or explicitly excluded by database or CLI rules.
+- Two retained target tracks never originate from the same source stream unless duplication is implemented explicitly as a separate feature.
+- If target-track metadata is rewritten after reordering, it is written onto the correct source-derived logical track rather than the track that merely occupies the same final output position.
+- Invalid target-to-source references fail deterministically before the conversion job is launched.
+- If a separate source file substitutes one target track, that track keeps its target slot and ordering while metadata is merged with separate-file values taking precedence when both sides provide the same field.
+- A test proving subtrack mapping must assert at least one of: exact `source_index` to output-order mapping, omission of named source tracks, or preservation of per-track metadata after reorder.
+
+## Test Notes
+
+- `tests/legacy/scenario.py` names pattern behavior as `Filter/Reorder Tracks`.
+- `tests/legacy/scenario_4.py` is the strongest end-to-end signal because it runs DB-backed conversion and reapplies source indices before assertion.
+- `tests/legacy/track_tag_combinator_2_0.py` and `tests/legacy/track_tag_combinator_3_4.py` sort result tracks by `source_index` before checking tags, which matches the intended identity model.
+- Legacy permutation combinators define permutations but their assertion functions are stubs.
+- Some legacy scenarios produce `AP` and `SP` selectors but do not execute them.
+
+## Risks
+
+- `src/ffx/media_descriptor.py` contains an explicit `rearrangeTrackDescriptors()` path whose current implementation appears defective and under-tested.
+- Separate-source-file metadata precedence is only partly expressed in current implementation paths and should be covered directly in the rewritten test suite.
+- Production code expresses the mapping contract more clearly than the legacy harness, so a rewrite should add direct logic-level tests for mapping and reorder planning.

+# Test Rewrite
+
+This file captures the structure executed by `tests/legacy_runner.py` today and
+defines the target shape for a complete rewrite.
+
+Detailed product rules for source-to-target subtrack mapping live in
+`requirements/subtrack_mapping.md`. This file describes only how tests cover
+that area.
+
+## Interpreter Requirement
+
+- Agents shall run Python-side test commands with `~/.local/share/ffx.venv/bin/python`.
+- This applies to the legacy harness, `unittest`, `pytest`, helper scripts, and `python -m ffx ...` test invocations.
+- Agents shall not silently substitute `python`, `python3`, or another interpreter for Python-side test work.
+- If `~/.local/share/ffx.venv/bin/python` is missing or not executable, agents shall stop and report the missing venv instead of continuing with Python-side test execution.
+
+## Shell Environment Requirement
+
+- Agents shall source `~/.bashrc` from an interactive Bash shell before running TMDB-dependent test commands or TMDB-dependent `python -m ffx ...` test invocations.
+- Agents shall not source `~/.bashrc.d/interactive/77_tmdb.sh` directly for normal test work; `~/.bashrc` is the required entry point.
+- In automation this means agents shall use an interactive Bash invocation such as `bash -ic 'source ~/.bashrc && ...'`, because a non-interactive `bash -lc` returns from `~/.bashrc` before the interactive fragments are loaded.
+- If sourcing `~/.bashrc` still does not provide required shell environment such as `TMDB_API_KEY`, agents shall stop and report the missing environment instead of continuing with TMDB-dependent test execution.
+
+## Current Harness
+
+- Entrypoint: `~/.local/share/ffx.venv/bin/python tests/legacy_runner.py run`
+- Runner style: custom Click CLI, not `pytest` or `unittest`
+- Commands:
+  - `run`: discover scenario files, instantiate each scenario, run yielded jobs
+  - `dupe`: helper command that creates duplicate media fixtures; not part of the test run
+- Filters: `--scenario`, `--variant`, `--limit`
+- Shared context:
+  - builds one mutable dict for the whole run
+  - installs loggers and writes `ffx_test_report.log`
+  - creates `ConfigurationController` eagerly
+  - tracks only passed and failed counters
+- Discovery:
+  - scenario files: `tests/legacy/scenario_*.py`
+  - combinators: `glob + importlib + inspect` by filename convention
+  - ordering: implicit glob order, no explicit sorting
+- Skip behavior:
+  - Scenario 4 is skipped when `TMDB_API_KEY` is missing
+  - only `TMDB_API_KEY_NOT_PRESENT_EXCEPTION` is caught at scenario construction time
+
+## Current Scenarios
+
+- `1`: `tests/legacy/scenario_1.py`
+  - focus: basename generation without pattern lookup or TMDB
+  - inputs per job: `1`
+  - jobs: `140`
+  - expected failures: `0`
+  - execution: build one synthetic source file, run `~/.local/share/ffx.venv/bin/python -m ffx convert`, assert filename selectors only
+  - selectors executed: `B`, `L`, `I`
+  - selectors defined but not executed: `S`, `R`
+- `2`: `tests/legacy/scenario_2.py`
+  - focus: conversion matrix over media layouts, dispositions, tags, and permutations
+  - inputs per job: `1`
+  - jobs: `8193`
+  - expected failures: `3267`
+  - execution: build one synthetic source file, run `~/.local/share/ffx.venv/bin/python -m ffx convert`, probe result with `FileProperties`, assert track layout and selected audio and subtitle metadata
+  - selectors executed: `M`, `AD`, `AT`, `SD`, `ST`
+  - selectors defined but not executed: `MT`, `AP`, `SP`, `J`
+- `4`: `tests/legacy/scenario_4.py`
+  - focus: pattern-driven batch conversion with SQLite state and live TMDB naming
+  - inputs per job: `6`
+  - jobs: `768`
+  - expected failures: `336`
+  - execution: build six synthetic preset files, recreate temp SQLite DB, insert show and pattern, run one batch convert command via `~/.local/share/ffx.venv/bin/python`, query TMDB during assertions
+  - selectors executed: `M`, `AD`, `AT`, `SD`, `ST`
+  - selectors defined but not executed: `MT`, `AP`, `SP`, `J`
+  - notes:
+    - uses `MediaCombinator6` only
+    - issues live HTTP requests through `TmdbController` with no request cache
+
+## Current Combinator Families
+
+- scenario files discovered: `3`
+- basename combinators discovered: `2`
+- media combinators discovered: `8`
+- media tag combinators discovered: `3`
+- disposition combinator 2 variants: `4`
+- disposition combinator 3 variants: `5`
+- track tag combinator 2 variants: `4`
+- track tag combinator 3 variants: `5`
+- indicator variants: `7`
+- label variants: `2`
+- show variants: `3`
+- release variants: `3`
+- permutation 2 variants: `2`
+- permutation 3 variants: `3`
+
+## Current Totals
+
+- full run without TMDB: `8333`
+- full run with TMDB: `9101`
+- Scenario 4 generated source files: `4608`
+- Scenario 4 live TMDB episode queries: `4608`
+
+## Current Behavior Areas
+
+- output basename rules for label, season and episode indicator, show name, and release suffix combinations
+- track layout normalization across the eight media combinator shapes from `VA` through `VAASSS`
+- two-track and three-track disposition edge cases, including intentional failure cases
+- two-track and three-track track-tag preservation checks, including checks that sort results by source identity
+- container-level media tag handling
+- pattern-backed conversion against a temporary SQLite database
+- TMDB-assisted episode naming for batch conversion
+
+## Structural Findings
+
+- The suite is process-heavy: most jobs run `ffmpeg` to generate a fixture and then spawn the FFX CLI as a subprocess.
+- The suite is integration-first and has almost no isolated unit-level coverage for pure logic.
+- The base `Combinator` class is a placeholder and is not the real abstraction boundary used by the suite.
+- Many combinator methods are placeholders: there are `25` `pass` statements across the current test modules.
+- Several assertion families are never executed because scenario selector dispatch is incomplete.
+- Scenario comments mention a Scenario 3, but no `scenario_3.py` exists.
+- `tests/legacy/_basename_combinator_1.py` is effectively orphaned because discovery only matches `basename_combinator_*.py`.
+- `tests/legacy/disposition_combinator_2_3 .py` contains an embedded space in the filename and is still part of discovery.
+- Expected failures are validated only as subprocess return-code matches, not as specific error types or messages.
+- The current suite depends on `ffmpeg`, `ffprobe`, SQLite, the local Python environment, and for Scenario 4 a live TMDB API key plus network access.
+
+## Rewrite Target
+
+- Replace the custom Click harness with a standard test runner, preferably `pytest`.
+- Split the suite into explicit layers: unit, integration, and optional external-system tests.
+- Keep unit tests as the default path and make them runnable without `ffmpeg`, `ffprobe`, TMDB, or a user config directory.
+- Model discovery explicitly in code instead of relying on glob-plus-reflection naming conventions.
+- Convert the current Cartesian-product combinators into readable parametrized cases grouped by behavior area.
+- Preserve the current behavior areas, but represent them with targeted cases instead of thousands of opaque variant IDs.
+- Make every assertion family explicit and executable; there must be no selector that is produced but never consumed.
+- Replace live TMDB access with fixtures or mocks in normal runs; any live-contract test must be opt-in.
+- Replace ad hoc subprocess return-code checks with assertions on typed exceptions, stderr content, or structured outputs.
+- Provide small reusable media fixtures or fixture builders so only a narrow integration slice needs `ffmpeg`-generated media.
+- Make database tests self-contained and fast through temporary databases and direct controller-level assertions.
+- Make ordering, naming, and selection deterministic so a contributor can predict exactly what will run.
+- Expose a small smoke suite for quick local runs and CI, plus a separately marked slower integration suite.
+- Prefer domain-oriented test modules over combinator-family modules: basename, pattern matching, metadata rewrite, track ordering, TMDB naming, CLI smoke, and failure handling.
+
+## Rewrite Acceptance
+
+- A default local test run finishes quickly and without network access.
+- A contributor can identify which behavior a failing test covers without decoding variant strings like `VAASSS-A:D10-S:T001`.
+- All current intended failure behaviors remain covered, but each one is asserted directly and readably.
+- The rewritten suite can be adopted by CI without requiring live TMDB credentials.
