Add git_fingerprint (root commit SHA-1) to managed_repos as a stable,
machine-independent identifier — identical across every clone regardless
of checkout path, remote URL, or SSH alias.
- Migration n1i2j3k4l5m6: adds git_fingerprint column + non-unique index
(non-unique to support repos that share ancestry via forks/splits)
- GET /repos/by-fingerprint?hash=<sha>[&remote_url=<url>]: lookup by
fingerprint; optional remote_url disambiguates shared-ancestry repos
- GET /repos/by-remote?url=<url>: fallback lookup by remote URL
- consistency_check.py --here [PATH]: auto-detects repo slug from any
local checkout via fingerprint (falls back to remote URL), then auto-
registers host_paths[hostname] so subsequent runs need no override
- --all now includes repos with host_paths[current_hostname], not just
those with local_path
- fix-consistency-here / check-consistency-here Makefile targets
- Fixed _api_get bug: httpx strips query strings when params={} is passed
- Backfilled fingerprints for 14 repos on this host

"""Add git_fingerprint to managed_repos
|
|
|
|
Stores the root commit SHA-1 of the git repository — a machine-independent
|
|
identifier that is identical across every clone regardless of remote URL,
|
|
checkout path, or protocol. Used by the consistency checker and other tools
|
|
to match a locally checked-out repo to its state-hub record without relying
|
|
on local_path or remote_url (both of which vary per machine).
