Tree page (/) gains every navigation dimension m asked for:
- Debounced search input matching title/slug/aliases/content_md/paths
case-insensitively (?q=…)
- Tag chip row (?tag=a,b — AND within tags, as before)
- Management chip row with ?mgmt=mai,self,external,unmanaged
(OR within management; "unmanaged" is the synthetic empty-array case)
- Status chip row with ?status=active,done,archived (default = active;
archived rows only surface when the separate show-archived toggle is on)
- Has-link chip row ?has=caldav-list,gitea-repo
- Each chip carries the count it would yield if toggled — honest user
cue, computed via per-dimension recomputation in pure Go (cheap at
m's scale)
- URL is the source of truth — every filter goes through the query
string, so any view is bookmarkable; HTMX swaps the tree-section in
place with hx-push-url=true on every chip click and on search keyup
- Empty-state copy with a clear-all link
Implementation:
- web/tree_filter.go new: TreeFilter struct + ParseTreeFilter +
QueryString/URL + Toggle* helpers + Matches + applyTreeFilter
(replacement for buildForest) + computeChipCounts.
- web/tree_filter_test.go: parse defaults + every dimension's match +
URL round-trip + ancestor-keep semantics + chip counting.
- Linkages: linkKindsByItem on Server fans across the two has-link
ref_types in one pass and feeds the filter.
- tree.tmpl reduced to a one-liner that calls tree-section; new
tree_section partial powers both the initial page render and HTMX
fragment swaps (matches the pattern from phases 2.a/b/d).
docs/design.md §4: tree-filter contract — URL keys, AND/OR rules,
count semantics, archived ergonomics.
caldav package:
- Todo carries URL, ETag, Raw so ListTodos rows can be PUT/DELETEd in place
- BuildVTodoICS for new VTODOs, ApplyVTodoEdit for in-place edits that
preserve unknown properties (DESCRIPTION, CATEGORIES, X-*)
- PutTodo/DeleteTodo with If-Match optimistic concurrency
- ErrPreconditionFailed/ErrNotFound for 412/404
- RFC 5545 fold-at-75 + CRLF + text escape, hand-rolled UUID v4
- httptest round-trip (create -> list -> complete -> delete) plus 412 path
web:
- POST /i/{path}/caldav/todo/{complete,reopen,edit,delete,todo-create}
- Re-fetches the live ETag before each PUT/DELETE so ordinary use never
trips 412; on actual 412 the section reloads with a banner
- Calendar URL must already be linked to the item (anti-forgery guard)
- tasks_section partial drives both the initial page render and HTMX
swaps; detail.tmpl reduces to a one-liner template call
docs/design.md §5: rewrite for full read/write semantics + ETag concurrency.
Big task. Five migrations, full store + web rewrite, and a model upgrade
that turns the parent_id tree into a parent_ids[] DAG.
Schema (db/migrations)
- 0006_tags_management_unify: adds tags + management text[] (GIN-indexed),
collapses the area/project distinction (kind keeps the slot but 'area'
is no longer a special value), drops the structural rules from the
path trigger so root projects + non-root projects are both legal.
- 0007_backfill_mai_projects: one-shot, idempotent — for every row in
mai.projects without a 'mai-project' item_link, create a projax.items
row under a heuristic-chosen area (mhealth→health, msports/manjin→
sports, kanzlai/hlckm/work/mworkrepo/paliad or HL/* repo→work,
mhome→home, default→dev), insert the item_link, and tag the row
management=['mai']. Also flips management='mai' on any already-linked
pre-Phase-1.5 promotions.
- 0008_mai_projects_sync: bidirectional triggers. sync_to_mai runs as
projax_admin and writes mai.projects directly (after the operator-run
grant + RLS policy widening — documented in the migration header).
sync_from_mai is SECURITY DEFINER so writes by the mai role fan out
into projax.items. pg_trigger_depth() + projax.in_sync GUC keep the
cycle suppressed. Slug stays the join key for new rows; the
item_link pointer survives renames.
- 0009_items_unified_simplify: view collapses to a thin projection over
projax.items now that mai.projects is a derived projection.
- 0010_multi_parent: parent_id → parent_ids uuid[], path → paths text[].
compute_item_paths walks via parents' precomputed paths (no recursive
CTE in the hot path; cycle detection uses one). New triggers:
items_check_slug_collision (multi-parent uniqueness),
items_after_delete (manual cascade since arrays don't carry FK).
Trigger refresh_item_paths_recursive does parent-first DFS over
descendants, guarded by projax.refreshing_paths GUC.
Go store + handlers
- Item gains ParentIDs []string + Paths []string. PrimaryPath /
OtherPaths helpers feed the detail breadcrumb. Source always
'projax' now; SourceRefDeref still surfaces the mai-id pointer.
- Update / Reparent / Create take ParentIDs []string. AddParent helper
for the multi-parent UI's "also list under" action.
- GetByPath uses '$1 = any(paths)' so /i/work.paliad and /i/dev.paliad
resolve to the same row.
- buildForest renders a multi-parent item under each of its parents
(duplicated nodes in distinct branches). Tag-filter prune is
branch-preserving.
Templates
- detail.tmpl: multi-select parents, tags + management chip inputs,
"Also at: …" breadcrumb for multi-parent items.
- new.tmpl: same multi-select + chip inputs.
- tree.tmpl: tag-filter chip bar, "×N" badge on multi-parent rows,
management chips visible on every row.
- classify.tmpl: re-parent workflow (no more promote-to-projax — the
bidirectional sync removed the dichotomy).
Tests (DB + HTTP, all skip without env)
- TestMultiParentResolvesBothPaths inserts an item with two parents,
asserts both inherited paths.
- TestSlugCollisionUnderCommonParent refuses a sibling clash.
- TestMultiParentBothPathsRouteToSameRow HTTP-level: /i/dev.X and
/i/work.X both 200, same row.
- TestReparentRoundTrip rewritten for parent_ids[] semantics.
- TestPathTriggerNestAndRename / Reparent rewritten to query paths[].
Docs (docs/design.md)
- §2 rewritten: items in a DAG, no area/project distinction.
- §3 schema: parent_ids + paths + tags + management + indices.
- §3.1 path-trigger overhaul incl. cycle detection via recursive CTE
and slug-collision-under-common-parent guard.
- §3.2 view simplified.
- §3.4 NEW: mai.projects bidirectional sync, including the manual
prereq.
- §4.1 + §4.2: classify becomes re-parent, tags+management UI section.
mai head start / mai hire / mai status / mai instruct keep working
because mai.projects retains its FK-target shape; the projax sync just
mirrors the row in lock-step.
mgmt.msbls.de is being retired; depending on it for auth was the wrong
direction. Match the mBrian / flexsiebels pattern instead — same
Supabase backend, but every tool runs its own login page and scopes
cookies to its own host.
Routes
- GET /login render a sign-in form (mBrian dark visual). If the
request already has a valid session, jump to a safe
redirectTo (or /).
- POST /login exchange email+password at /auth/v1/token?grant_type=
password, set cookies, 302 → redirectTo or /. On
Supabase 4xx, re-render the form with the error.
- POST /logout clear both cookies (Max-Age=-1) + 302 → /login.
Cookies
- access_token + refresh_token only. No Domain attribute → scope is
projax.msbls.de exclusively. HttpOnly, Secure, SameSite=Lax, Path=/,
Max-Age=1y. Matches mBrian + flexsiebels per-host pattern.
Middleware
- /healthz, /login, /logout always pass through (otherwise infinite
redirect on the probe / login page).
- On invalid/expired session → 302 /login?redirectTo=<safe-path>,
RELATIVE to projax. No more cross-host bounce.
- Cookie refresh on expiry still rotates both cookies in place.
- Bearer header path kept for scripted clients.
safeRedirect
- Path-only. Rejects "", "//*", "https://*", "\*", control-char
injection. Cross-host or scheme bounces fall back to "/". Tested
against the obvious bypasses.
Cleanup
- Drop PROJAX_LOGIN_URL + PROJAX_COOKIE_DOMAIN env vars (unused now).
- main.go: log "auth: own-login enabled" with the supabase URL on
startup; warn loudly when SUPABASE_URL is unset.
- README trust-model section rewritten: own login, per-host cookies,
same backend.
- layout.tmpl gains a "sign out" form-button in the nav so the tree /
detail / classify pages can log out without curl.
Tests (14, no DB needed): stub Supabase via httptest covers
healthz/login/logout exemption, anonymous→/login redirect, valid
cookie + Bearer pass-through, stale-refresh rotation with NO Domain
attribute, hard-fail redirect, GET form render with redirectTo carry,
already-signed-in short-circuit, POST success with correct cookies,
POST bad-creds error surface, redirectTo safety (path-only, no //,
no absolute URLs), logout cookie clearance.
Full suite (incl. DB-backed): 27/27 green with PROJAX_SKIP_MIGRATE=1.
cmd/projax/main.go boots a pgxpool against PROJAX_DB_URL (falls back to
SUPABASE_DATABASE_URL), auto-applies embedded migrations on start
(disable with PROJAX_AUTO_MIGRATE=off), and serves on PROJAX_LISTEN_ADDR
(default :8080).
store package wraps the unified view + projax.items writes. Item has
helper methods for templates: IsArea, Editable, SourceRefDeref. The
Promote() flow runs the insert + item_links link inside a single
transaction so the source row drops out of items_unified atomically.
web package: per-page html/template instances parsed against a shared
layout.tmpl, embedded static/style.css, HTMX from CDN. Pages:
GET / tree of items_unified
GET /i/{path} detail (editable for projax, read-only +
promote form for mai.projects)
POST /i/{path} update projax-native item
POST /i/{path}/promote one-page promote (HTMX-aware fragment for
inline classify)
GET /new?parent={path} create form
POST /new create projax-native item
GET /admin/classify orphan list with inline HTMX promote
GET /healthz DB ping
GET /static/* embedded assets
Auth is intentionally out of scope for v1 — service binds to whatever
PROJAX_LISTEN_ADDR points at, deploy guidance pins it to the Tailscale
interface (covered in 1d README).
Tests (skip when DB env is unset):
TestTreeRenders, TestHealthz,
TestDetailProjaxNativeEditable, TestDetailMaiProjectsReadOnly,
TestClassifyListsOrphans, TestPromoteRoundTrip.
