fix: system health is a Settings tab, not a page only the dot reached

The surface shipped at /system with no nav entry, reachable only by
clicking the health dot beside the brand — a target you have to already
suspect something is wrong to go looking for. Operator-flagged: it needs
a path someone can walk to.

Settings is where you go to ask the instance about itself, so the view
becomes a tab there, beside Activity — Activity answers "what is the
queue doing", System answers "is anything left to do it".

- SystemView.vue moves to components/settings/SystemHealthTab.vue; the
  content is unchanged apart from shedding its own container and h1.
- SettingsView adopts useTabQuery (the composable Browse and
  Subscriptions already use) so a tab can be linked TO. The health dot
  now points at ?tab=system, and /system redirects there so the previous
  build's link and any bookmark still land.
- The tab drops its own 10s poll. v-window keeps a visited item mounted
  rather than destroyed, so that timer would have gone on firing behind
  Maintenance — and TopNav already polls the same store every 15s for
  the dot.

+# TEMPORARY — milestone 328. Delete once the baseline has shipped and settled.
+#
+# Collapsing 89 alembic revisions into one baseline has exactly one dangerous
+# failure: the baseline does not reproduce the schema the chain produced, and
+# the divergence surfaces later, on the operator's live data, in whatever
+# migration comes next.
+#
+# So the comparison happens in CI, against a throwaway pgvector Postgres, where
+# nothing is at risk. It answers one question: does `upgrade head` on the
+# collapsed tree produce the same schema as `upgrade head` on the full chain?
+#
+# The chain is read out of GIT, not the working tree, which is what lets this
+# keep working now that the revisions are deleted — `chain_ref` names a commit
+# that still carries 0001..0089. That is the whole reason this is a workflow
+# rather than a script someone ran once.
+#
+# WHAT THIS CANNOT SEE, and it matters: the comparison is of SCHEMA. Migrations
+# 0002 and 0003 also INSERTED rows (the import_settings and ml_settings
+# singletons), and the application reads those with scalar_one(), which raises
+# on an empty result. A baseline that omitted them would produce an identical
+# schema, pass this check with a perfect diff, and crash a fresh install on its
+# first settings access. Only running the app against a new database finds
+# that class of defect. Do not read a green run here as "the baseline is
+# correct" — read it as "the schema is correct".
+#
+# Autogenerate now emits nearly all of the baseline unaided, which was NOT true
+# before #3275 put the previously migration-only objects onto the models — the
+# HNSW index with its opclass, the COALESCE expression index, the partial
+# unique indexes, 107 server_defaults, the enum CHECKs. An earlier attempt at
+# this squash was reverted precisely because the generator dropped them all
+# silently. What still needs hand-adding is only what cannot live in a model:
+# the two CREATE EXTENSION statements, the two seed rows, and the pgvector
+# import the generator forgets to write.

+      # should fail — blank lines, SQL comments, trailing whitespace, and:
+      #
+      #   \restrict / \unrestrict — a per-invocation RANDOM NONCE that newer
+      #   pg_dump emits to fence the dump against injection during restore. It
+      #   differs on every run by construction, so it is noise by definition,
+      #   not a schema difference. Measured on run 4960, the control: two dumps
+      #   of the SAME schema came back 1123 lines each and differed on exactly
+      #   these two lines and nothing else. That control is what licenses this
+      #   filter — it was observed to be the only false positive, rather than
+      #   assumed to be one.
+      # Column ORDER inside a CREATE TABLE is compared separately from column
+      # CONTENT, and only content is fatal.
+      #
+      # A table built by 87 migrations has its columns in ADD COLUMN order; the
+      # same table built in one shot has them in declaration order. That is a

+# Contributing
+
+FabledCurator is developed by a single maintainer for their own use, and
+published because it may be useful to others. That shapes what contribution
+looks like here.
+
+**Issues are welcome** — bug reports, and questions about running it, are
+genuinely useful and often the fastest way to find out that something is
+broken outside the one environment it was built in.
+
+**Open an issue before writing a pull request.** Not as a formality: the
+project has opinions that are not obvious from the code, and it is unpleasant
+for everyone when a finished patch turns out to conflict with one. A short
+issue first costs you nothing and may save you an evening.
+
+**Contributions are licensed under the AGPL-3.0**, like the rest of the
+project. By submitting one you agree it ships under that licence. There is no
+CLA and no copyright assignment.
+
+## Running it for development
+
+```bash
+docker compose up -d          # UI on http://localhost:8080
+```
+
+The dev override (`docker-compose.override.yml`) is auto-merged and builds the
+app images locally from source, so this needs no `.env` and no registry
+access. Postgres and Redis ports are exposed on the host.
+
+## What CI checks
+
+Every push runs these, and they are the definition of done for a change:
+
+```bash
+ruff check backend/ tests/ alembic/ agent/ scripts/   # lint (and import order)
+pytest tests/ -m "not integration"                    # backend unit tests
+pytest tests/ -m integration                          # needs pgvector + redis
+cd frontend && npm run test:unit && npm run build     # frontend
+```
+
+The integration lane builds its schema by running the real migrations
+(`alembic upgrade head`), never from ORM metadata — so a migration that does
+not apply cleanly fails CI rather than being discovered later.
+
+Note for the linter: ruff's isort runs with `order-by-type`, which sorts
+ALL-CAPS names ahead of CamelCase. `from sqlalchemy import JSON, DateTime, ...`
+is correct; putting `JSON` alphabetically between `Integer` and `String` is
+not. This catches people out.
+
+## Database changes
+
+The ORM models and the migration chain must agree. This is enforced, and it is
+enforced because they silently diverged for a long time and nobody noticed
+until they were compared: the models were missing indexes, defaults and
+uniqueness guarantees that only ever existed inside a migration, which made
+`alembic revision --autogenerate` actively unsafe to run.
+
+So: if you change a model, write the migration; if you write a migration,
+change the model to match. Both, in the same commit.
+
+Adding a value to a CHECK-constrained column means swapping the constraint in
+the same change — the constraint is not documentation, and a new value without
+it fails at insert time.
+
+## Branch model
+
+`dev` is where work happens. `main` is production and is only reached by a
+merge from `dev`, never pushed to directly. If you are sending a pull request,
+target `dev`.
+
+## Style
+
+Match the surrounding code. The one convention worth stating explicitly is
+that comments here explain *why*, especially where a choice looks wrong at a
+glance — a comment recording which migration a constraint came from, or why a
+default is a `text()` rather than a string, is the kind that has repeatedly
+turned out to be worth its space.

+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are 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.
+
+  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.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  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 Affero 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. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  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 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 work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero 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 Affero 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 Affero 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 Affero 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 Affero 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 Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  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 AGPL, see

 # FabledCurator
 
-Self-hosted media curation — gallery, ML tagging, and subscription-driven downloading in one app. Part of the FabledSword family.
+<!-- overview:start -->
+Self-hosted media curation — a gallery, ML auto-tagging, and subscription-driven
+downloading in one application. Part of the FabledSword family.
 
-Combines what was [ImageRepo](https://git.fabledsword.com/bvandeusen/ImageRepo) (gallery, ML, importer) and [GallerySubscriber](https://git.fabledsword.com/bvandeusen/GallerySubscriber) (gallery-dl wrapper, subscriptions, credential capture) into a single product.
+## What it does
 
-## Status
+You point it at creators you follow. It downloads what they post, files it,
+tags it, and gives you something better than a folder full of images to look
+through afterwards.

+  similarity-driven Explore view, and a page-turning reader for series.
+- **Subscriptions.** Follows creators on Patreon, SubscribeStar, Pixiv and
+  anything `gallery-dl` supports, on a schedule. Handles paywalled posts using
+  your own logged-in session.
+- **ML tagging.** Runs image models in-container to suggest tags, group
+  characters, find near-duplicates and power similarity search. Suggestions are
+  reviewable — it proposes, you confirm, and it learns which proposals you keep
+  rejecting.
+- **Deduplication and provenance.** Everything that arrives is hashed and
+  deduplicated by content, metadata sidecars are read wherever the source
+  writes them, and every file keeps a record of where it came from.
+- **Maintenance.** Backups, library audits, thumbnail and embedding backfills,
+  orphan cleanup — all from the UI, all as background jobs you can watch.
+
+Everything is configured from the Settings UI and stored in the database. There
+is no config file to edit beyond a handful of bootstrap environment variables.
+<!-- overview:end -->
+
+## Before you expose it
+
+**FabledCurator has no login.** There are no user accounts, no passwords and no
+permission model. Anything that can reach the port is an administrator.
+
+That matters more here than it would in most self-hosted apps, because of what
+this one stores: **live platform session cookies for Patreon, SubscribeStar and
+Pixiv** — accounts that usually have a payment method attached. Whoever reaches
+the port can read them, alongside your entire library.
+
+So:
+
+- Bind it to a LAN, a VPN, or a tunnel you control.
+- Do not port-forward it. Do not put it on a public hostname.
+- A reverse proxy that adds TLS but no authentication **does not help**. If you
+  want it reachable from outside, put an authenticating proxy in front of it —
+  a forward-auth provider, HTTP basic auth, an identity-aware tunnel — and treat
+  that layer as the only thing standing between the internet and your accounts.
+
+This is a deliberate design decision for a single-operator tool on a trusted
+network, not a bug and not an oversight. It is stated here because it decides
+how you are allowed to deploy it. [SECURITY.md](SECURITY.md) covers the rest of
+the threat model.
+
+## Requirements
+
+- **Docker** with Compose v2.
+- **~4 GB RAM** for the app, plus whatever Postgres needs for your library size.
+- **Disk** for your media, plus several GB for ML model weights.
+- **No GPU required.** The ML worker runs on CPU — tagging and embedding are
+  slower, and that is the whole difference. A GPU is only involved if you
+  separately run the optional agent (below), which is a different machine's job.
+
+## Install
+
+```bash
+git clone https://git.fabledsword.com/bvandeusen/FabledCurator.git
+cd FabledCurator
+
+cp .env.example .env
+$EDITOR .env          # set DB_PASSWORD and SECRET_KEY
+
+docker compose -f docker-compose.yml up -d
+```
+
+Then open <http://localhost:8080>.
+
+**The `-f docker-compose.yml` is required, not decoration.** Compose
+auto-merges `docker-compose.override.yml` when you leave it off, and that
+override builds the images locally from source — the contributor path, not
+yours. Naming the file explicitly skips the override and pulls the published
+`:latest` images, which is the stable channel built from `main`.
+
+If you forget it, the symptom is a long build instead of a quick pull.
+
+## First run
+
+The database schema is created automatically on first start — the web container
+runs its migrations before serving. Nothing to initialise by hand.
+
+**One thing does need a deliberate act, and the app will not start without it.**
+FabledCurator encrypts your stored platform credentials with a key it keeps at
+`./images/secrets/credential_key.b64`. On a brand-new install that file does not
+exist, and rather than quietly creating one the app stops:
+
+```
+MissingCredentialKey: Fernet key file not found at /images/secrets/credential_key.b64
+```
+
+Set `CURATOR_BOOTSTRAP_NEW_KEY=1` in your `.env` for the first `up`, then delete
+the line once the container is running. `.env.example` ships it with that
+instruction attached.
+
+The refusal is deliberate, and worth understanding rather than working around:
+auto-creating a key is indistinguishable from the disaster case — a restore that
+brought the database back but lost `./images/secrets` — where it would mint a key
+that cannot decrypt anything, leaving an instance that looks healthy while every
+paywalled download fails. Making you say so once, on an empty install, is the
+price of that not happening silently later.
+
+**Which means: back up `./images/secrets/` alongside your database.** It is the
+only thing that can read your stored credentials. A database restored without it
+needs every credential entered again by hand.
+
+A few other things are worth knowing about the first few minutes:
+
+- **The ML worker downloads its model weights on first boot**, several GB from
+  HuggingFace into `./models`. Until that finishes, tagging is queued rather
+  than broken. It is idempotent — a restart resumes rather than refetches.
+- **The gallery starts empty**, and that is the expected state. Add a creator
+  under **Subscriptions** and it fills as posts come down.
+- **If you already have a library on disk**, there is no screen that imports
+  it, and there is not going to be one. Folder ingestion had a UI until July
+  2026; it was retired once posts began arriving entirely through
+  subscriptions and the browser extension, and the decision to leave it
+  retired is deliberate — the folder path carries complexity the product does
+  not need in order to do its job. The supported way to fill a new install is
+  to add the creators you follow under **Subscriptions** and let it pull.
+
+  The `/api/import/trigger` endpoint is still wired up for anyone who wants to
+  script a one-off against a folder mounted at `./import`, and its progress
+  shows under **Settings → Activity**. Treat it as an unsupported escape
+  hatch rather than a feature: nothing in the UI drives it and nothing else
+  in this README depends on it.
+- **To download from a paywalled account**, FabledCurator needs that account's
+  session — see the browser extension below. Without one it can still fetch
+  public posts.
+- **Check Settings → Overview** to confirm the workers are alive. Every long
+  operation in FabledCurator is a background job, so if the queues are not
+  running, the UI will look like it is ignoring you rather than like it is
+  broken.
+
+## The browser extension
+
+A Firefox extension does two jobs: it hands your logged-in platform sessions to
+FabledCurator so it can download on your behalf, and it adds a creator as a
+subscription in one click from their page.
+
+It ships **inside the web image** — there is no add-on store listing to find.
+Go to **Subscriptions → Settings**, find the *Browser extension* card, and click
+**Install Firefox extension**. The XPI is Mozilla-signed, so Firefox installs it
+like any other add-on; the button serves it directly rather than making you
+download and side-load a file.
+
+It pairs with your instance using an API key generated automatically on first
+use. The bar directly under that card shows the key and can rotate it.
+
+See [extension/README.md](extension/README.md) for what it does in detail.
+
+## The GPU agent
+
+Optional, and separate. If you have a desktop with a graphics card, you can run
+an agent on it that leases ML jobs from FabledCurator over HTTP, does them on
+the GPU, and hands the results back. It never touches the database or Redis, so
+it is safe to run somewhere the rest of the stack is not.
+
+Run it for a burst of tagging, stop it to get your card back. It deploys from
+`agent/docker-compose.yml`, not the main stack — see
+[agent/README.md](agent/README.md).
+
+## Upgrading
+
+```bash
+docker compose -f docker-compose.yml pull
+docker compose -f docker-compose.yml up -d
+```
+
+Migrations run automatically on start. Take a database backup first — Settings →
+Maintenance has one — because the schema moves forward and does not move back.
+
+## Deployment posture
+
+FabledCurator is built to run inside a homelab over plain HTTP. It does not
+generate certificates, redirect to HTTPS, or set HSTS. If you want TLS,
+terminate it at your reverse proxy. See [Before you expose it](#before-you-expose-it)
+for why TLS alone is not enough.
+
+## Troubleshooting
+
+**The UI loads but nothing ever finishes.** The web container is up and the
+workers are not. `docker compose -f docker-compose.yml ps` — check `worker`,
+`scheduler` and `ml-worker` are healthy, not restarting.
+
+**`docker compose up` started building instead of pulling.** You left off
+`-f docker-compose.yml`, so the dev override took over. See [Install](#install).
+
+**Downloads fail with an auth error.** The stored session for that platform has
+expired. Re-capture it with the extension; sessions do not last forever.
+
+**Which build am I running?** The foot of Settings shows a version and a
+channel, and `/api/health` returns the same two fields. There are no version
+tags on the images, so this is the authoritative answer.
+
+---
+
+# Developing FabledCurator
+
+Everything below is about working on FabledCurator rather than running it. If
+you are installing it, you are done — see [CONTRIBUTING.md](CONTRIBUTING.md) if
+you want to send a patch.
+
+## Status and channels
+
+In production. `main` is continuously deployed — every merge builds and
+publishes `:latest`, so whatever is on `main` is what is running. Day-to-day
+work happens on `dev`, which publishes `:dev`.
+
+For local development, the dev override handles everything:
+
+```bash
+docker compose up -d          # note: no -f, so the override applies
+```
+
+That builds the images from source, turns on DEBUG logging, and exposes
+Postgres and Redis on the host. No `.env` required.
+
+## Versions and tags
+
+Three image tags exist, and no others:
+
+| Tag | Branch | Meaning |
+| --- | --- | --- |
+| `:latest` | `main` | Production. Moves on every merge. |
+| `:c-<sha>` | `main` | Immutable — the rollback unit, all three images together. |
+| `:dev` | `dev` | The rolling test channel. Moves on every push. |
+
+There are deliberately **no version tags**. Nothing pins one, and a per-build
+name nobody reads is upkeep for a model FC does not run (family rule 145; the
+reasoning is note #3127 §5). Rolling back is `docker pull …:c-<sha>`.
+
+Each artifact still has a version, derived rather than chosen: the commit time
+of the newest change to that artifact's *own* shipped files, as
+`YYYY.MM.DD.HHMM` UTC (rule 148). Four artifacts, four independent versions —
+a push touching only `agent/` re-versions the agent and leaves web and ml
+alone, and CI skips the builds whose content did not move.
+
+Because no registry name carries it, the running instance's own report is the
+only answer to "which build is this?". The foot of Settings shows
+`FabledCurator 2026.08.29.0201 · dev`, and `/api/health` returns the same two
+fields.
+
+Release tags are optional bookmarks — FC went twelve weeks without one and
+nothing was wrong. Pushing `v<version>` publishes a Forgejo release listing the
+commits since the previous tag; it builds no image.

-## Quick start
-
-For local development and testing, just:
-
-```bash
-docker compose up -d
-# UI: http://localhost:8080
-```
-
-That uses sane dev defaults baked into `docker-compose.yml` and the dev
-override (`docker-compose.override.yml`, auto-merged) — local builds, DEBUG
-logging, exposed Postgres + Redis ports on the host. No `.env` required.
-
-For a production-like deployment, override the dev defaults via shell env
-or a `.env` file (see `.env.example` for the variable names) and use:
-
-```bash
-docker compose -f docker-compose.yml up -d
-# (skips the override so containers pull registry images)
-```
-
-The GPU agent is deployed separately, on the machine with the card —

+issue on the repository that says only that you have a security report — no
+reproduction steps, no affected endpoint, no payload — and a maintainer will
+reply with a private contact to send the details to.
+
+That is a deliberately awkward first step, and it exists because the
+alternative is worse: an issue tracker is public the moment it is written to,
+and every self-hosted instance stays vulnerable until its operator has had a
+chance to update.
+
+Please include, once you have a private channel:
+
+- what an attacker can do, and what access they need to start
+- the version or commit you tested
+- reproduction steps
+
+## Scope — what this software actually handles
+
+FabledCurator is self-hosted and holds things worth stating plainly, because
+they shape what counts as a serious bug here:
+
+- **Platform credentials.** The app captures and stores session cookies for
+  third-party subscription sites (Patreon, SubscribeStar, Pixiv) so it can
+  download on the operator's behalf. These are live credentials for accounts
+  that usually carry a payment method. Anything that discloses them, decrypts
+  them, or lets one user of a shared instance read another's is high severity.
+- **An extension API key.** The Firefox extension authenticates to the backend
+  with a shared key. Anything that leaks it or lets it be bypassed is a way in.
+- **No authentication of its own.** This is the most important thing on this
+  page. FabledCurator has no login, no user accounts and no permission model —
+  there is no `User` table and no session auth anywhere in the backend. Every
+  HTTP client that can reach the port is the administrator, with full read and
+  write access to everything above, including the stored platform credentials.
+  Access control is entirely the operator's job, done at the network layer.
+  Reports that an unauthenticated caller can reach an endpoint are therefore
+  describing the design; reports that something *crosses the network boundary
+  the operator drew* — an SSRF, a request forgery that rides a browser the
+  operator already has open, a path that leaks state to an origin the operator
+  did not authorise — are in scope and are serious.
+- **Arbitrary media from the internet.** Downloaded files are decoded, hashed,
+  thumbnailed and fed to ML models. Anything that turns a hostile file into
+  code execution is in scope.
+
+## Deployment posture — read this before reporting
+
+FabledCurator is designed to run **inside a private network, over plain HTTP,
+reachable only by its operator**. It does not terminate TLS, redirect to
+HTTPS, or set HSTS; if you want transport security, terminate it at your
+reverse proxy. It also does not authenticate anyone — see above. These are
+documented design decisions, not oversights.
+
+Putting this on the public internet, with or without TLS, hands whoever finds
+it your Patreon, SubscribeStar and Pixiv sessions. A reverse proxy that adds
+TLS but not an authentication layer does not change that.
+
+Reports that reduce to "the application is served over HTTP", "there is no
+HSTS header", or "the API needs no credentials" describe those decisions
+rather than vulnerabilities. Reports that the operator can cause the software
+to do something destructive are usually also by design — the operator is the
+administrator of their own instance.
+
+What remains in scope is everything that crosses a boundary the software is
+actually supposed to hold: between untrusted downloaded content and the host,
+between a third-party origin and an operator's open browser session, and
+between the credentials at rest and anything that is not the operator.
+
+## Supported versions
+
+Fixes land on the `main` branch and reach the `:latest` image. There are no
+maintained release branches — the supported version is the current one, and
+the remedy for a security issue is to update.

-
-Revision ID: 0022
-Revises: 0021
-Create Date: 2026-05-26
-
-Closes the operator-flagged 2026-05-26 issue where the filesystem importer
-called _find_or_create_source(url=sd.post_url), creating one Source row per
-imported post URL. Operator's Atole artist had 406 Source rows where there
-should have been 1 (the /cw/Atole subscription Source).
-
-Source represents a subscription feed (one per artist+platform — the
-gallery-dl URL polled by the FC-3 downloader). Posts hang off it. The
-filesystem importer was misusing Source as a per-post key.
-
-Migration steps per (artist_id, platform) group with >1 Source:
-  1. Pick canonical — prefer a URL NOT matching '/posts/<id>$' (real
-     campaign URL like /cw/Atole); else min(id).
-  2. PRE-merge any Posts under non-canonical sources whose
-     external_post_id ALREADY exists under the canonical source. (Same
-     gallery-dl post imported via two different sidecar paths can plant
-     two Post rows with identical external_post_id under different
-     Sources for the same artist.) Repoint ImageProvenance +
-     ImageRecord.primary_post_id to the canonical-side Post, dedupe
-     ImageProvenance against alembic 0021's uq, then delete the
-     non-canonical-side Post. This MUST happen before step 3 — Postgres
-     fires uq_post_source_external_id row-by-row during the bulk UPDATE
-     and the merge-after-reparent ordering 500s on first collision
-     (operator-hit during v26.05.26.1 deploy, 2026-05-26).
-  3. Reparent remaining Posts onto canonical (no collisions possible now).
-  4. Reparent ImageProvenance.source_id off the non-canonical sources.
-  5. Delete the orphan Source rows.
-  6. If the canonical Source's URL still looks like a per-post URL (no
-     campaign URL existed among candidates), rewrite it to
-     'sidecar:<platform>:<artist_slug>' so the artist detail page shows

-"""sidecar-audit followup: correct external_post_id + post_url across all platforms
-
-Revision ID: 0025
-Revises: 0024
-Create Date: 2026-05-27
-
-Closes the operator-flagged 2026-05-27 sidecar audit findings. Three
-data-correctness bugs across non-Patreon platforms had been silently
-corrupting Posts since FC-3 shipped; the parser fix (sidecar.py, same
-commit) addresses new imports. This migration cleans up existing rows.
-
-Per-platform actions:
-
-  subscribestar — gallery-dl wrote the per-attachment id in `id` and
-    the actual post id in `post_id`. FC's parser picked `id`, so every
-    multi-image SubscribeStar post was fragmented into N Post rows.
-    1. For each SubscribeStar Post, read its sidecar (via the related
-       ImageRecord's on-disk path), pull `post_id`, overwrite
-       external_post_id and post_url.
-    2. Merge groups of Posts under one source that now share an
-       external_post_id (fragments of the same actual post). Same
-       ImageProvenance pre-delete + repoint dance as alembic 0022.
-
-  hentaifoundry — sidecars have NO `url` field; `src` is the image
-    URL. FC's parser stored post_url=NULL. Read each HF Post's sidecar
-    for `user` + `index`, derive the canonical /pictures/user/<u>/<i>
-    permalink. external_post_id (= `index`) was already correct.
-
-  discord — gallery-dl wrote the CDN attachment URL in `url`. FC's
-    parser stored that as post_url. Read each Discord Post's sidecar
-    for the server/channel/message triple, derive the proper
-    discord.com/channels/.../<message> permalink. external_post_id (=
-    `message_id`) was already correct.
-
-  pixiv — pure-SQL backfill: replace any `i.pximg.net`-style URL on
-    Post.post_url with the derived `/artworks/<id>` permalink. Pixiv
-    external_post_id (= `id`) was already correct; no sidecar IO
-    needed.
-
-Idempotent: re-running on already-corrected data is a no-op (skips
-rows whose derived value matches what's already stored).
-
-Posts whose related ImageRecord paths don't resolve on disk (orphaned
-filesystem state) are skipped with a count in the migration output —
-those will be picked up by a future deep-scan.

-"""collapse-sidecar-synthetic: repoint Posts/ImageProvenance/DownloadEvents
-from `sidecar:<platform>:<slug>` synthetic Source anchors onto the real
-Source for the same (artist, platform) when one exists, then delete the
-synthetic.
-
-Revision ID: 0028
-Revises: 0027
-Create Date: 2026-05-31
-
-Background: alembic 0022 (2026-05-26) consolidated the old per-post-URL
-Source rows into one canonical Source per (artist, platform). When NO
-real campaign URL was salvageable among the candidates, it rewrote the
-canonical row to url='sidecar:<platform>:<slug>' enabled=false as a
-disabled anchor for any Posts already attached.
-
-That was fine while it was the only Source for that artist+platform.
-But: the unique constraint on Source is (artist_id, platform, url), not
-(artist_id, platform). When the operator later added the real
-subscription via the UI / extension / etc., a SECOND row landed —
-the real one — with id > the synthetic. Both coexisted.
-
-Two follow-on problems surfaced 2026-05-31:
-
-  1. The Subscriptions UI listed both rows. The synthetic was disabled
-     so the scheduler never polled it, but it looked like a phantom
-     subscription. (Fixed in same commit by SourceService.list filter.)
-  2. importer._source_for_sidecar picked Source by `ORDER BY id ASC
-     LIMIT 1`, so EVERY gallery-dl download since the real Source was
-     added attached its Post to the SYNTHETIC anchor, not the real
-     Source. (Fixed in same commit by preferring non-sidecar URLs.)
-
-This migration is the data half of the cleanup: for every (artist,
-platform) with both a synthetic AND a real Source, repoint the
-synthetic's children (Posts, ImageProvenance, DownloadEvents) onto the
-real Source and delete the synthetic. Reuses the same epid/provenance
-collision dance from alembic 0022 because the same uniqueness
-constraints fire row-by-row during bulk UPDATEs.
-
-Lone synthetic anchors — those where no real Source for the same
-(artist, platform) exists (e.g., filesystem-imported artist with no
-subscription added) — are LEFT INTACT. They anchor real imported
-content; deleting them would CASCADE-delete the Posts the operator
-imported. The SourceService.list filter hides them from the UI; the
-operator can delete them by hand if they want the underlying imports
-gone.

-"""nullable post.source_id + denormalized post.artist_id; retire sidecar synthetics
-
-Revision ID: 0030
-Revises: 0029
-Create Date: 2026-06-01
-
-Operator-asked 2026-06-01 after the Dymkens orphan investigation: the
-sidecar synthetic Source pattern (`sidecar:<platform>:<slug>` rows
-with enabled=false) was technically correct but misled the operator
-into thinking they had phantom subscriptions. The synthetics existed
-solely to satisfy `Post.source_id NOT NULL` for filesystem-imported
-content with no real subscription.
-
-This migration makes the data model honest:
-
-1. **Post gets a denormalized `artist_id` column** so artist filters
-   work without traversing `Post → Source.artist_id`. Backfilled from
-   the existing Source linkage, then NOT NULL'd.
-2. **`Post.source_id` becomes nullable**, FK ondelete `CASCADE` → `SET
-   NULL`. Deleting a Source detaches its Posts instead of destroying
-   imported content (semantically: subscription ends, archive stays).
-3. **`ImageProvenance.source_id` becomes nullable** with the same FK
-   semantic change.
-4. **Sidecar synthetic Sources are deleted** — first NULL out the
-   FKs from Post + ImageProvenance pointing at them (so the implicit
-   CASCADE doesn't fire), then delete. DownloadEvent FK is unchanged
-   (still CASCADE'd, NOT NULL'd) — synthetics have `enabled=false`
-   so no events exist for them.
-
-Uniqueness handling: the existing `uq_post_source_external_id`
-(source_id, external_post_id) keeps working for source-bound Posts
-(Postgres treats NULL != NULL so NULL-source rows aren't deduped by
-it). A second partial unique index covers the NULL-source case on
-(artist_id, external_post_id) so filesystem-imported posts still
-dedupe within an artist.

-predictions had no other consumer), and the allowlist was a second, un-earned
-auto-apply path parallel to heads. Both are retired — drop their storage.

+"""The whole schema, in one migration.
+
+This replaces alembic revisions 0001..0089 — the entire build-out of the
+project, 89 files and ~6,000 lines that a new installation used to replay in
+order to arrive at a schema this file creates in one pass. Nothing about the
+resulting database changes; what goes away is the requirement that a stranger
+re-run our development history to get it.
+
+## Why the revision id is 0089
+
+`revision = "0089"` and `down_revision = None` are both deliberate, and the
+combination is the entire migration strategy for existing installations.
+
+An already-deployed database has `alembic_version = '0089'`, because it ran the
+real 0089. This file claims that same id, so alembic reads the version table,
+sees head already reached, and does nothing at all. No stamp is needed — which
+matters because `alembic stamp` writes a version string without validating
+anything about the schema it is writing it against, and a stamp that is wrong
+is indistinguishable from one that is right until the next migration fails.
+
+An empty database has no version row, so alembic runs this file and then
+records `0089`. Both paths converge on the same schema and the same version,
+and neither requires anyone to assert anything by hand.
+
+The next migration written after this one is `0090`, exactly as it would have
+been. The numbering is continuous across the collapse on purpose.
+
+## What was added to the generated output, and why
+
+`alembic revision --autogenerate` produced almost all of this from the models,
+which is only true because #3275 first made the models actually describe the
+schema. Before that reconciliation the generator silently omitted eleven
+indexes and three uniqueness guarantees, and an earlier attempt at this squash
+had to be reverted for exactly that reason.
+
+Four things still had to be added by hand, because they are not in the models:
+
+1. **`CREATE EXTENSION vector`** (from 0001) and **`tsm_system_rows`** (0004).
+   Extensions are database objects, not table metadata, so no model can carry
+   them. `IF NOT EXISTS` because a re-run must not fail.
+
+2. **Three seed inserts** — the two settings singletons (0002, 0003) and the
+   three hygiene system tags (0075). Some migrations did not only build schema;
+   they inserted rows the product needs in order to function, and nothing in
+   the application ever creates them. Every consumer reads them with
+   `scalar_one()`, which RAISES `NoResultFound` on an empty result rather than
+   returning None, so their absence is a crash and not a degradation.
+
+   Distinguishing these from the other data statements in the chain is the
+   whole trick, and the rule turns out to be mechanical:
+
+     * `INSERT ... VALUES (...)` with literal values is a SEED. It creates
+       something the product ships. It must be carried.
+     * `INSERT ... SELECT ... FROM <table>` is a BACKFILL. It derives rows
+       from rows that already exist, so on an empty database it inserts
+       nothing and carrying it would be pointless. 0034 (artist_visit), 0040
+       and 0047 (series_chapter) are all of this shape and are correctly
+       absent here.
+
+   This category is invisible to every automated check this project has:
+   `baseline.yml` compares SCHEMA, and a baseline missing all three seeds still
+   produces a byte-identical schema and a perfectly green diff. What caught the
+   system tags was the integration suite — 36 tests failing on
+   `NoResultFound` — after a first version of this file shipped with only the
+   two settings rows. A first-run check against the real application is the
+   only thing that finds this class of defect.
+
+3. **The `pgvector` import.** Autogenerate emits qualified
+   `pgvector.sqlalchemy.vector.VECTOR(...)` references without importing the
+   package, so the file it writes cannot execute — `NameError: name 'pgvector'
+   is not defined`, observed on run 4988.
+
+The other data statements in the old chain were deliberately NOT carried over.
+0023's `DELETE FROM tag WHERE kind IN (...)`, and 0047's `series_page` /
+`series_chapter` deletes, are historical cleanups that operate on rows an empty
+database does not have.
+
+## Downgrade
+
+There is none. A baseline's downgrade would be "drop the entire schema", which
+is not a migration but a data-loss event wearing one as a disguise. Restore
+from a backup instead — that is what backup_run exists for.

+Milestone 365. Nothing in FabledCurator knew what was SUPPOSED to be running:
+`celery inspect` reports the workers that answer, so a dead worker was a
+shorter list rather than a red light, and the only surface that could tell an
+operator otherwise was Portainer. This table is the memory that turns an
+absence into something the app can see.
+
+Keyed on the queue set for a celery role and on agent_id for the GPU agent —
+NOT on the celery worker name, which here is `celery@<container id>` and is
+minted fresh on every deploy. See the model docstring for why that choice is
+the whole design.
+
+## First migration on the collapsed baseline
+
+0089 is the single generated baseline that replaced revisions 0001..0089
+(milestone 328). This is the first revision written on top of it, so it is
+also the first evidence that the chain steps forward from the collapse rather
+than merely reproducing the schema — which nothing had demonstrated yet.
+
+An existing install is at 0089 because it ran the real 0089; a fresh one is at
+0089 because it ran the baseline. Both arrive here identically, which was the
+property the collapse was designed around.
