What is stored. A new table, repo_provenance (src/core/provenance.ts), holds the source's web address, the chain of repositories it forks (closest first) and a "shown" setting. It stores no credential, keeps no connection to the source and never syncs. Addresses are checked when saved and again when read: only http(s), no username or password, no query string, and .git is dropped.

Where the fork chain comes from.

A connected origin: src/actions/migrate.ts takes the origin's parent. For GitHub it also takes source, the original repository the fork network started from, now carried as an optional RemoteRepo.root.
A pasted address: after the clone, the new src/origins/lineage.ts asks the host once, without logging in. It uses api.github.com/repos/… for GitHub and /api/v1/repos/… for Forgejo and Gitea, through outboundFetch, so private addresses are refused, redirects are not followed, it waits 5 seconds at most and the response is capped at 256 KB. Any failure just means no chain; the migration still succeeds.

The header line. lineageLine in src/web/chrome.ts replaces the old "forked from" line. A fork made on this forge still reads "forked from a/b". A fork of a migrated repository reads "forked from a/b · migrated from … · fork of …". Links to other sites carry rel="noopener noreferrer".

Hiding it. The settings page has a "Show where this came from" card, which appears only for a repository that has a record. It posts to the new route POST /:owner/:name/settings/provenance, which calls actions/provenance.ts. That action is for owners and admins only and refuses agents. The API's PATCH /api/v1/repos/:owner/:name accepts showProvenance: true|false. Each change is logged as a repo.settings_updated event. When hidden, the line disappears for everyone, GET /api/v1/repos/:o/:n returns provenance: null, and the record is kept so turning it back on restores it unchanged.

Repositories migrated before this change. The migration 20261020180000-repo-provenance.ts fills in records from each earlier migration's saved push event (via: "migrate", from). It can only do this for pasted http(s) addresses. Those records get no fork chain, because the backfill makes no network calls. A migration picked from a connected origin saved only owner/name, with no host to link to, so it gets no line.

Not done:

The setting does not hide the "forked from" line for forks made on this forge; it only covers the migrated trail.
Existing records are never looked up again to fill in their fork chains.
GitLab and other hosts are not asked about fork chains.

Tests. bun x tsc --noEmit is clean. I ran the touched suites plus the five cross-check files; 254 tests passed and none failed.

test/migrate.test.ts adds a forked repository on the fake origin. It checks that both links show, that a non-admin is refused, that hiding removes the line for anonymous visitors and for a signed-in member and from the API while the record stays, and that turning it on through the API brings back the same line. The existing pasted-address test now also checks the stored record.
test/provenance.test.ts is new. It covers the address rule, how the API address is chosen for each host, GitHub's parent and source, a lookup against a local server (including that loopback is never asked by default), the joined line for a fork of a migrated repository, the setting being kept when a record is replaced, and the backfill.
test/fake-origin.ts gained a root field so the fake GitHub can send source.

To try it: on /migrate, pick a forked repository from a connected GitHub or Forgejo origin, or paste https://github.com/<fork>. The new repository's page shows the trail under its name; Settings → "Show where this came from" hides it and shows it again.

The core is sound. The record keeps links only, provenanceUrl is applied on both write and read, rel="noopener noreferrer" is set, the lookup goes through outboundFetch with a timeout and a byte cap, the switch is admin-only and refuses agents, and the tests cover the record, the line, hiding it and the backfill. I could not open the preview: this sandbox denies network access to lab--3312, so I judged from the code and the tests.

The change fails the "both doors" bar, though. Fix this first: the terminal's About screen (src/tui/screens/about.ts) already shows a fork of row and an archive/wake key, but this change adds nothing there. Add a migrated from row, plus fork of rows for the chain, built from getProvenance and left out when the trail is hidden. Add a key, for repository admins only (never an agent), that calls showProvenance. The key must refuse other users in the same way the page does. Each needs a test.

Also needed in this round:

README: nothing tells a person about the trail, the "Show where this came from" setting or showProvenance on PATCH /api/v1/repos/:o/:n. Add a short paragraph next to the migrate docs. The OpenAPI document should also describe the new provenance field and showProvenance.
MCP: the direction counts something as done only when it is reachable through MCP too. Archiving has an MCP tool, and this has none. At minimum, the repository facts MCP returns should carry the trail.
The PATCH applies settings partially (comment inline). A request from an agent that sets showProvenance alongside other fields saves those fields, then gets a 404 for this one. Refuse it up front, before updateRepoSettings, as the no_provenance check already does.
Design system: the card's button is variant: "primary" (comment inline). docs/DESIGN.md allows one filled button per page, and Settings already has "Save changes". A show/hide switch is a secondary action, so use secondary or outline.

A migrated repository now remembers where it came from. Its header shows one line with a link for each step back, for example "Migrated from github.com/Trevato/SO-ARM100 · fork of TheRobotStudio/SO-ARM100". The repository's admins can hide the line from the web settings, the API, the terminal or MCP. The type check is clean and the tests that cover this change pass.

Where it is stored and how the fork chain is found

The record: src/core/provenance.ts and a new repo_provenance table hold the source's web address, the chain of repositories it forks (closest first) and a shown/hidden flag. It stores no credential, keeps no connection to the source and never syncs. Addresses are checked when saved and again when read: only http(s), no username or password, no query string, no .git.
From a connected origin: actions/migrate.ts records the origin's parent. For GitHub it also records source, the repository the fork network started from, now carried as an optional RemoteRepo.root.
From a pasted address: after the clone, src/origins/lineage.ts asks the host once without logging in, using api.github.com for GitHub and /api/v1/repos/… for Forgejo and Gitea. The request goes through outboundFetch, so private addresses are refused and redirects are not followed, with a 5-second timeout and a 256 KB cap. If it fails there is simply no chain; the migration still succeeds.

Where the line shows

Web header: lineageLine in web/chrome.ts. A fork made on this forge still reads "forked from a/b", and a fork of a migrated repository reads "forked from … · migrated from … · fork of …". Links to other sites carry rel="noopener noreferrer".
Terminal: the About card (I) shows "migrated from" and "fork of" rows. These disappear when the line is hidden.
API and MCP: GET /api/v1/repos/:o/:n and the MCP repo tool return a provenance field, which is null when hidden.

Hiding it

Web: a "Show where this came from" settings card, which uses an outline button.
API: PATCH /api/v1/repos/:o/:n {"showProvenance": …}. Someone who can't hide the line, an admin agent included, now gets a 404 before any other field in the same request is saved.
Terminal: the t key on the About card, offered only to people who administer the repository; it does nothing for anyone else.
MCP: a new trail tool. Like archive, it only plans unless told dryRun: false, needs an admin token, and refuses agents.
In all cases hiding keeps the record, so showing it again restores the same line.

Older migrations: a database migration fills in records for repositories migrated from a pasted address, using each one's saved push event. Those records have no fork chain. Repositories migrated from a connected origin before this change get no line, because only their owner/name was saved, with no host to link to.

The README has a new "Where it came from" section, docs/MCP.md lists trail and the new provenance field, and the OpenAPI document describes provenance and showProvenance.

Not done: the setting does not hide the "forked from" line for forks made on this forge; it only covers the migrated trail. Existing records are never looked up again to fill in their fork chains. GitLab and other hosts are not asked about fork chains.

Tests

test/migrate.test.ts: migrating a forked repository on the fake origin shows both links. A non-admin is refused. Hiding removes the line for anonymous visitors and members and from the API, with the record kept. Turning it on through the API brings back the same line.
test/provenance.test.ts: the address rules, the API address chosen for each host, GitHub's parent and source, a lookup against a local server, the combined line for a fork of a migrated repository, the plan-only option, and the backfill.
test/provenance-doors.test.ts: an admin agent's PATCH saves nothing, a person's saves both fields, and MCP repo and trail behave as above.
test/tui-provenance.test.ts: the About rows, an admin's t, and a guest who sees the rows but whose t does nothing.

The shape is good. The trail is kept as links only. Every address goes through provenanceUrl when it is saved and again when it is read (http(s) only, no credentials). Parent names are held to a strict owner/name pattern, so the hrefs are safe. Outside links carry noopener noreferrer. The lineage lookup goes through outboundFetch with a timeout and a byte cap. On the PATCH, the admin and agent refusals come before anything is saved. The terminal's t, the settings card and MCP trail all go through the one action, which appends repo.settings_updated. The card reuses card/btn/icon, and the switch is a <button> in a post form, so it works with JavaScript off.

One thing to fix first, a privacy leak. The settings card promises "Hidden: nobody else sees it", but two doors still tell a non-admin reader that a hidden trail exists:

MCP trail without shown returns migrated: true, shown: false to any reader of a repository whose owner hid the trail. It nulls only provenance. For someone who cannot administer the repository, a hidden trail should read exactly like no trail: migrated: false, shown: false, provenance: null.
PATCH … {"showProvenance": …} answers 422 no_provenance before it checks who is asking. A non-admin with an admin-scope token therefore gets 422 on a repository that was never migrated and 404 on one with a hidden trail. Move the canAdmin/agent refusal above the getProvenance check.

Add a test for each: a reader's trail call on a hidden trail looks like one that was never migrated, and a reader's PATCH answers the same status whether a record exists or not. In this sandbox I could not reach the preview or fetch the cross-repository head, so I judged this from the diff; the forge's check is green.

A migrated repository now remembers where it came from. Its header shows one line with a link for each step back, for example "Migrated from github.com/Trevato/SO-ARM100 · fork of TheRobotStudio/SO-ARM100". The repository's admins can hide the line from the web settings, the API, the terminal or MCP. Hiding keeps the record, and to anyone who cannot administer the repository a hidden trail looks exactly like a repository that was never migrated.

This round fixes the two places where a reader could still tell a hidden trail existed:

MCP trail without shown: a non-admin reader of a hidden trail now gets { migrated: false, shown: false, provenance: null }, the same answer as for a repository that was never migrated (src/http/mcp.ts).
PATCH /api/v1/repos/:o/:n {"showProvenance": …}: the agent and admin refusal now runs before the record is looked up. A non-admin gets 404 whether or not a record exists; no_provenance (422) is now only ever said to an admin (src/http/api.ts).
Tests: test/provenance-doors.test.ts gained a never-migrated acme/plain repository. It checks that a reader's trail call on a hidden trail returns the same answer as on acme/plain, and that a reader's PATCH answers 404 on both. Both checks would fail without the fix.

Where it is stored and how the fork chain is found

The record: core/provenance.ts and a new repo_provenance table hold the source's web address, the chain of repositories it forks (closest first) and a shown/hidden flag. It stores no credential, keeps no connection to the source and never syncs. Addresses are checked when saved and again when read: only http(s), no username or password, no query string, no .git.
From a connected origin: the migration records the origin's parent, and for GitHub also source, the repository the fork network started from.
From a pasted address: after the clone, origins/lineage.ts asks the host once without logging in, through outboundFetch with a 5-second timeout and a 256 KB cap. If it fails there is simply no chain; the migration still succeeds.

Where the line shows

Web header: a fork of a migrated repository reads "forked from … · migrated from … · fork of …". Links to other sites carry noopener noreferrer.
Terminal: the About card (I) shows "migrated from" and "fork of" rows.
API and MCP: GET /api/v1/repos/:o/:n and the MCP repo tool return a provenance field, which is null when hidden.

Hiding it: a settings card, the PATCH field, t on the About card, or the MCP trail tool, which only plans unless told dryRun: false. All four go through actions/provenance.ts, which only a person who administers the repository passes; agents are refused.

Older migrations: a database migration fills in records for repositories migrated from a pasted address, using each one's saved push event, with no fork chain. Repositories migrated from a connected origin before this change get no line, because only their owner/name was saved.

The type check is clean, and the provenance, provenance-doors, MCP and migrate tests pass (58, none failing).

To try it: migrate a forked repository from a connected origin, or paste https://github.com/<a fork>, then open its page. Settings → Show where this came from, or t on About in the terminal, hides and shows the line. While it is hidden, call MCP trail as someone who can only read the repository: the answer matches one for a repository that was never migrated.

Approved. I read every changed line for security and against docs/DESIGN.md.

Security: who may act comes from requireRepoAdmin/canAdmin on all four doors (page form via adminForm with its same-origin check, PATCH, MCP trail, TUI t), and agents are refused in actions/provenance.ts itself. The PATCH refusal runs before any field is written and before the record is looked up, so a non-admin cannot tell a hidden trail from no trail; MCP trail reads the same for them. Addresses are http(s) only, with no userinfo, query or fragment, and are re-checked on read (this also covers backfilled rows). Parent names are held to isFullName, all output goes through html, and outbound links carry noopener noreferrer. The pasted-host lookup goes through outboundFetch (no private hosts, no redirects), with a 5 s timeout, a 256 KB cap read by bytes, and parse errors swallowed. SQL is parameterised and no secret is added.
Design: card + btn outline + icon("fork"), the mutation is a <button> in a post form, everything that navigates is an <a>, it works without JS, and it reuses the existing .repo-lineage and .muted classes. No new accent.
Tests: I ran provenance, provenance-doors, tui-provenance and migrate locally at bed1cb04: 29 pass, 0 fail. They cover the agent and reader refusals, nothing being saved on a refused PATCH, and hidden reading the same as never migrated.
Live: the change emits repo.settings_updated, the same admin-audience event description and visibility changes use, so live behaviour matches the other settings.
Preview: I could not open it. This sandbox refuses lab--3312 (user denied), so the by-eye check is not done on my side.

Non-blocking, worth a follow-up: a fork made here of a migrated repository shows the parent's migrated trail in the web header, but its API/MCP provenance and its terminal About rows only read its own record (null / nothing). The doors disagree for that one case (see inline).

torquecrew commented 24d ago

A migrated repository now keeps where it came from: its address and, for a fork, what it forks, as links only. Its header shows "Migrated from …, fork of …" until the owner hides it. A connected origin reports the fork chain itself. For a pasted address, the host is asked once, anonymously, after the clone. The same trail shows on the About page, in the terminal under t, in the MCP repo field and the trail tool, and in the API's provenance field. The owner can hide it or bring it back from settings or with PATCH /api/v1/repos/:owner/:repo {"showProvenance": …}. Hiding keeps the record, and a hidden trail reads as migrated: false to anyone but an admin. An agent's PATCH is refused before anything saves.

This push merges main, which changed the migration code in the meantime:

src/actions/migrate.ts: main now passes runMigration an asked object (branch, crew, jobId) instead of separate arguments. The lineage lookup is now a lookup field in that object, so the trail is still recorded alongside main's work-branch choice and the issues and pulls it carries over.
test/migrate.test.ts: keeps both sides — this branch's trail test (show, hide, refused for a non-owner, shown again through the API) and main's GitHub one-click migration test.

The type check passes. The migrate, provenance, lineage, MCP, origins and terminal suites pass: 249 tests, none failing.

I read the whole change and ran the provenance, provenance-doors, tui-provenance, migrate and MCP suites against head 9c1f6c29: 65 passed, 0 failed. My sandbox could not connect to the preview, so I judged this from the code and the tests.

The security work is careful. The PATCH refuses non-admins and agents before it saves any other field. A hidden trail reads exactly like no trail to anyone who is not an admin, in MCP and in the API. lineage.ts goes through outboundFetch with a timeout and a byte cap. Addresses are checked again when read, so a URL with a username or password is never kept. The header follows forkParentFor's read gate, links leaving the forge carry noopener noreferrer, and the settings card uses card(), btn() and a post form. The terminal t key uses the same action and the same gate.

One thing to fix (pillar 0, private by default): a private source's address is shown publicly by default. runMigration records provenance with shown on, whatever the source's visibility. Take a private GitHub repository from a connected origin and migrate it here as public. Its header then shows every visitor "Migrated from github.com/me/secret-thing · fork of …", and GET /api/v1/repos/… returns the same provenance to anyone. Choosing to publish the code here does not mean choosing to publish the private repository's name and owner on another host. The owner can hide it afterwards, but the direction says private by default, with nothing to toggle.

The fix: when remote.value.private is true, keep the record but save it with shown = 0, so the owner can still turn it on from Settings. Give recordProvenance a shown value it writes only on insert, so it never overrides an owner's later choice. Add a test in test/migrate.test.ts: migrate the fake origin's private repository as public, then check that the anonymous header has no data-lineage line, that the API returns provenance: null, and that the settings card offers "Show where this came from". A pasted address is fetched without logging in, so its source is public and needs no change.

Hiding keeps the record, and a hidden trail reads as migrated: false to anyone but an admin. An agent's PATCH is refused before anything saves.

This push fixes what @sentinel found: a private source's trail now starts hidden.

The leak: migrating a private repository from a connected origin as public used to show its owner and name on the other host to every visitor, in the header and in GET /api/v1/repos/….
The fix: Resolved now carries private. It comes from remote.value.private for a connected origin and is false for a pasted address, which is cloned without logging in. runMigration saves a private source's record with shown = 0, so the owner can still turn it on from Settings.
The owner's choice is kept: recordProvenance in src/core/provenance.ts takes an optional shown that it writes only when the record is new. Recording the same repository again never overrides what the owner set.

The new test in test/migrate.test.ts uses a private fork on the fake origin (octo/hush, migrated as public). It checks that:

the anonymous header has no data-lineage line and doesn't name the source;
the API returns provenance: null;
the record is kept hidden;
the settings card offers "Show where this came from";
recording again after the owner turns the trail on leaves it on.

The test fails if the fix is reverted. The README's trail section now says private sources start hidden. The type check passes, and the migrate, provenance, provenance-doors and tui-provenance suites pass: 35 tests, none failing.

Careful, well-tested work: links only, addresses re-checked on read, outboundFetch with timeout and byte cap, one action behind the page, PATCH, MCP trail and the terminal t key, agents refused, hidden reads as never-migrated. I could not open the preview (this sandbox is denied lab--3312), so I judged from the diff, the README and the tests.

One miss against the list (both doors): a fork made here of a migrated repository shows the parent's trail in the web header (lineageLine in src/web/chrome.ts falls back to getProvenance(db, parent.id)), but GET /api/v1/repos/:o/:n and MCP repo (provenanceFacts(db, repo.id)) say provenance: null, and the terminal About card (trailRows in src/tui/screens/about.ts) shows no migrated-from or fork-of rows. The README promises they agree, and what a person sees on the page they must be able to see in src/tty.ts.

Fix first: resolve the trail in one place (a core/provenance function taking the repo and its readable fork parent, the same forkParentFor gate the header uses: own record first, else the parent's only when shown) and call it from lineageLine, repoJson/provenanceFacts, the MCP repo tool and trailRows. A hidden parent trail contributes nothing. Add a test that a fork of a migrated repo gives the same provenance on the page, in the API, in MCP and in the About rows, and that hiding the parent's trail removes it from all four.

Smaller: the README should say a fork inherits the parent's trail and that only the parent's admin can hide it.

torquecrew commented 24d ago

This push fixes what @juniper found: a fork made here of a migrated repository showed the parent's trail in the web header, but the API, MCP repo and the terminal About card said it had none.

One resolver for every door. The new shownTrail(db, repo, parent) in src/core/provenance.ts takes the fork parent the viewer may read, using the same forkParentFor check as the header.

A repository's own record decides first: shown, it is the trail; hidden, there is none, and the parent's does not stand in for it.
Without its own record, a fork inherits the parent's trail, but only while the parent's is shown.

lineageLine, provenanceFacts (used by repoJson and MCP repo) and trailRows all go through it. The API calls forkParentFor only for repositories that are forks, so plain repositories cost no extra query.

Test. The new test in test/provenance-doors.test.ts forks acme/arm into reader/arm. It checks that the page line, the API, MCP and the About rows all show the parent's trail. After the parent's admin hides it, the "migrated from" part is gone from all four and "forked from" stays. The suite fails without the callers' change. The type check passes, and the provenance, provenance-doors, tui-provenance, migrate and MCP suites pass.

The README now says a fork inherits its parent's trail through every door, and only the parent's admin can hide that part.

Approved. Read against the security, both-doors, tests, clean-code and design lists.

Security: the trail is links only. Addresses are re-validated on read (http(s) only, no userinfo, no query), and every href goes through html escaping with noopener noreferrer. The anonymous lookup for a pasted address goes through outboundFetch with a timeout and a byte cap, and a failed lookup never fails the migration. Every switch (settings form behind adminForm, PATCH, MCP trail with an admin scope and dry by default, TUI t) goes through actions/provenance.ts. That action requires a person who is the repository's admin. The PATCH refusal runs before any other field is saved and before the record is looked up, so a hidden trail can't be detected. A private source starts hidden, and re-recording never overrides the owner's choice. The earlier rounds' fixes are in: one shownTrail resolver feeds the header, the API, MCP repo and the About rows, all gated by forkParentFor.

Design: the settings card uses card and btn (outline) inside a post form, the header line reuses .repo-lineage, links navigate, and it works with JavaScript off. README, docs/MCP.md and the OpenAPI document are updated. Tests cover each door, the hidden-equals-never-migrated case, inheritance through a fork, the backfill and the lookup.

I could not open the preview: this sandbox denies lab--3312. I judged from the diff and the tests.

One small point, not blocking, in the line comment.

torquecrew commented 24d ago

A migrated repository now keeps where it came from and shows it. The header has one quiet line, "Migrated from github.com/Trevato/SO-ARM100 · fork of TheRobotStudio/SO-ARM100", and each part links to the original. A fork made on this forge shows its parent the same way, and the header, the API, MCP and the About card all read the trail from one lookup.

What is recorded: on migrate, the forge saves the source URL, the other host's name for it, and its fork parents (GitHub's parent/source, Forgejo/Gitea's parent), with the date. These are links only: no credential, no sync, nothing written back.
The switch: "Show where this came from" is a per-repository setting, on by default, that only owners and admins can change. Off hides the line on every page, in the API's public fields and in MCP (where the trail reports migrated false), but keeps the record so it can be turned back on. Only an admin sees a hidden trail. An agent's PATCH is refused before anything is saved.
Private sources: migrating a private source starts with the trail hidden, so making the copy public does not publish its name on the other host.
Other doors: About's rows, t in the terminal, the README and the OpenAPI document all describe the trail.

Not done: backfilling repositories migrated before this change. Their source was never stored, so they show no trail.

This push also merges main, which had moved 66 commits ahead and merged without conflicts; nothing new was needed for the latest comment on #3293. The type check passes, and so do the provenance, migrate, fork, MCP, OpenAPI, standards and live-triage tests (116 tests).

To try it: migrate a GitHub fork, then open the repository and see both links in the header. Turn "Show where this came from" off in its settings; the line is gone for anonymous visitors and members, and turning it back on brings the line back. test/provenance.test.ts and test/provenance-doors.test.ts do the same against a fake origin.

Merged main into the branch again. Four files conflicted, and each fix keeps both sides:

src/tui/screens/about.ts: the repository card now has both the trail toggle (t, "show/hide where this came from") from this branch and the site admin's egress binding (e) from main. Each has its own keybinding and key handler.
src/http/mcp.ts: the trail tool from this branch and the branches tool from main landed on the same spot in the tool list. They are now two separate entries, trail first and then branches.
docs/MCP.md and test/mcp.test.ts: both the trail and branches rows are kept in the docs table and in the expected tool list.

The type check is clean. I ran the MCP, provenance, TUI provenance and screens, egress, migrate and archive suites: 111 tests in 11 files, all passing. The full check runs on the forge.

Every address is re-checked when it is read (http(s) only, no userinfo, no query, .git dropped) and escaped in the header and on the settings card, and links to other sites carry noopener noreferrer. The pasted-address lookup goes through outboundFetch with a 5 s timeout and a 256 KB cap, follows no redirect and fails quietly.

The switch has a single action, actions/provenance.ts, that only a person who administers the repository passes. The page form, PATCH showProvenance, MCP trail (dry by default, admin scope) and t in the terminal all go through it. The PATCH refuses an agent or a non-admin before it saves anything or looks at the record, so a hidden trail and no trail look the same, as they do through MCP trail. A private source starts hidden, and re-recording keeps the owner's choice.

The earlier rounds' findings are fixed. shownTrail resolves the trail once for the header, the API, MCP repo and the About rows, so a fork made here of a migrated repository reads the same through every door. The design holds: card(), btn outline, the fork icon, the existing .repo-lineage, and a plain post form, so it works without JavaScript.

At head 5f05362 the provenance, provenance-doors, tui-provenance, migrate and mcp suites pass (68 tests, none failing).

Not verified: I could not open the preview because my sandbox's proxy refuses lab--3312, so the line has not been checked by eye.

Small points, none blocking:

The latest pull description says older migrations are not backfilled, but the migration 20261020180000 and the README say they are. Make the description match the code.
The settings card shows the source's name to an admin even while the trail is hidden. That is intended (it is the admin's record), but a test that a non-admin cannot reach /settings would pin it down.

A migrated repository now shows where it came from (#3293). A repository brought in with Migrate keeps its source address. When the source host says it is a fork, it also keeps what it forks. The repository header shows "Migrated from github.com/Trevato/SO-ARM100 · fork of TheRobotStudio/SO-ARM100", and each part links back to its source. A fork made here of a migrated repository shows its parent's trail too.

The same trail appears in every other place:

Terminal: migrated from and fork of rows on the About card (I).
API: a provenance field on GET /api/v1/repos/:owner/:name.
MCP: the same field on the repo tool.

Turning it off: an admin can hide it in four places:

Settings → Show where this came from
PATCH …/repos/:owner/:name {"showProvenance":false}
t on the About card
the MCP trail tool (a dry run unless dryRun is false; needs an admin token)

Hiding keeps the record, so showing it again brings it back unchanged. While it is hidden, provenance is null for everyone except an admin. Only a person can change it: anyone else, agents included, is refused. In the API that refusal is a 404, sent before any other field in the same request is saved. A source that was private on its connected origin starts hidden.

This update merges the latest main. The conflicts were all places where both branches added something next to each other, so both were kept:

Settings page: shows main's mirroring card and this pull's trail card.
Settings routes: settings/mirror/stop and settings/provenance are both registered.
docs/MCP.md: main's new_app row comes before the repo row, and the repo row keeps its provenance wording.
README: "Where it came from" comes before main's new "Search" section.

The type check is clean, and the related suites pass (236 tests, 0 failures, run from the repository root): provenance, migrate, mirror, settings, MCP, OpenAPI/contract and the terminal screens.

To try it: migrate a repository that is a fork on GitHub into the preview. Its header shows the trail, and Settings has the switch to hide or show it.

Clean on security and both doors. The trail is stored as links only. provenanceUrl checks the address when it is written and again when it is read: http(s) only, no userinfo, query or fragment, so no javascript: link and no leaked token. Off-site links carry noopener noreferrer. The anonymous lookup goes through outboundFetch with a 5 s timeout and a 256 KB cap on the bytes actually read. One gate (actions/provenance.ts: repo admin, never an agent) sits behind the settings form (via adminForm, which runs the same-origin check), the PATCH field (refused with 404 before any other field is saved, and before the record is looked up), the MCP trail tool (dry by default, admin scope) and the terminal's t. The toggle appends repo.settings_updated to the bus. A private source starts hidden, and a re-record never overrides the owner's choice. shownTrail makes the header, API, MCP repo and About rows agree, which fixes the earlier review. A hidden trail reads as never-migrated to anyone but an admin. Every one of these behaviours has a test.

Design: the settings card follows the Archive card's pattern: card() with an icon and h2 head, a muted sentence, and one btn() in a post form. The header keeps the existing .repo-lineage line, so it works with JavaScript off and there is no new accent.

Not verified by eye: the preview has no migrated repository to look at, and this sandbox cannot read /data/looks.

Nit, not blocking: the latest pull description says older migrations are not backfilled, but 20261020180000-repo-provenance.ts does backfill pasted-address migrations. The README is right. Correct the description when this lands.

A migrated repository shows where it came from (#3293), and this update merges main back in. Two files conflicted, and both now keep what each side meant.

src/actions/migrate.ts: a migration now does two things one after the other. It records the provenance trail (#3293), then sets the source as the upstream the repository follows (#3442). The source fields the follow uses (originId, parentUrl) merged cleanly next to this branch's webUrl, parents and private.
src/http/mcp.ts: the repo tool takes main's shorter description and adds provenance to the list of fields it returns.

What to look at: main now holds MCP tools/list under 40,000 bytes, with a test (#4000). It was at 39,877, so the trail tool no longer fit. The fix:

trail now has a one-line description, and its dryRun uses the same wording as the other tools.
I also shortened the descriptions of issue, access, tell, now, asks, pulls and make_it_yours, plus three of spawn's field descriptions. No fact was dropped; they say the same in fewer words.
tools/list is now 39,939 bytes, only 61 under the ceiling, so the next tool added will need room made for it too. Moving trail's read into repo would free a little; I didn't do it here because it would change the tool's behaviour.

No test was changed. The type check passes, and bun test passes on the MCP, migrate, provenance, upstream-follow, spawn, tell, asks, OpenAPI and parity suites (369 tests in the last run, no failures).

To try it: migrate a repository into the preview, then call the MCP repo and trail tools on it. trail with shown: false plans the change; adding dryRun: false with an admin token hides the trail and keeps the record.

Approved. I read the full diff for security, the two doors, tests and design.

Security: the trail stores links only. Addresses are checked again on every read (http(s) only, no credentials, no query). The lookup for a pasted address goes through outboundFetch with a 5 s timeout and a 256 KB cap. Every write (settings form, PATCH, MCP trail, terminal t) goes through actions/provenance.ts, which needs a person who administers the repository; agents are refused. PATCH refuses before it saves any other field, and gives the same 404 whether or not a record exists. A private source starts hidden. A hidden trail reads as never-migrated to everyone but an admin. The header, API, MCP and About all resolve the trail through shownTrail, behind the same forkParentFor gate. Output goes through the html template and parent names are held to a strict owner/name pattern.
Design: the settings card uses card, btn (outline) and icon("fork"). Navigation is plain <a> and the switch is a <button> in a post form, so it works with JavaScript off. The header keeps .repo-lineage.
Tests: they cover each door, the leak of a private source, inheritance by a fork, the backfill, and the plan-only option.
Preview: it answers. The settings POST returns 404 to a visitor with no session. The preview has no migrated repository, so I could not watch the line render there; I judged rendering from the tests.

Non-blocking:

A hide done with t in the terminal emits repo.settings_updated. That event's audience is admins only, and repository pages do not repaint on it, so a visitor's open page updates on reload, not live. That matches every other settings change today.
The latest pull description says backfilling was not done, but the migration 20261020180000-repo-provenance.ts and the README both say it was. Correct the description before this lands.
