Implementation Details
Table Inspector (/tables/[tableId]):
TableMetadataHeader: Displays native table identity, namespace, engine badge (postgresql, sqlite, mysql, mariadb), completeness status (COMPLETE, PARTIAL, RESTRICTED), snapshot indicator, and action links to the ER Canvas, Dependency Explorer, and Schema Explorer.
TableSummaryCards: Stat counters for columns, primary keys, foreign keys, unique constraints, check constraints, and indexes. Clicking any card switches the active tab.
ColumnsTab: Ordinal column table with client-side sorting, text filtering, primary/foreign key badges, and expandable column inspection rows.
ConstraintsTab: Constraint inspection supporting multi-column composite primary keys, composite foreign key mappings, referential actions (ON UPDATE, ON DELETE), unique constraints, and inert check constraint expressions.
IndexesTab: Index inspection displaying indexed columns, uniqueness, and primary status.
DependenciesTab: Immediate upstream and downstream dependencies with cycle status detection and direct link to the Dependency Explorer.
RawMetadataTab: Formatted JSON representation of the canonical table object with clipboard copy action.
Advanced Schema Search (/search):
SchemaSearchStudio: Cross-schema search coordinator with 300ms debouncing, in-flight cancellation via AbortController, and keyboard shortcut (/).
SearchFiltersPanel: Object type pills (tables, views, columns, constraints, indexes, namespaces), schema selector, namespace selector, constraint category filter, active filter badges with reset.
AccessibleDependencyTable: Semantic HTML table for 100% WCAG 2.2 AA non-visual dependency inspection.
Universal Object Inspector Abstraction:
InspectorObjectKind (table, view, materialized_view, collection, document_type, database_resource) and InspectorObject model for future NoSQL/Cloud resource extensibility without misrepresenting document collections as relational tables.
Strict Security & Zero-AI:
Zero AI/LLM dependencies, zero heuristic guessing, 100% untrusted text rendering preventing XSS, and workspace isolation headers.

Review comments at @apps/web/src/app/(app)/dependencies/[objectId]/page.tsx:
- Around line 16-19: The dynamic dependencies route reads objectId but does not
use it, so deep links open the default explorer instead of focusing the
requested object. Extract the DependenciesPage body into a shared
DependenciesView that accepts focusTableId, use it from both routes, and render
it here with objectId; do not add props to the page default export.
Review comments at @apps/web/src/app/(app)/tables/[tableId]/page.tsx:
- Around line 145-146: Set isSnapshot to false instead of deriving it from
snapshotId, so an unverified query parameter cannot trigger the immutable
snapshot banner; keep snapshot metadata from being presented as verified until a
snapshot response is available.
Review comments at
@apps/web/src/components/schema-search/SchemaSearchStudio.tsx:
- Around line 96-97: Update the search crawl in SchemaSearchStudio to check
cancelled before each schema iteration and each table-detail request, exiting
the stale search before it issues further API calls; preserve the existing final
setRawResults guard.
- Around line 105-106: Update the table filtering logic around matchesTable to
derive each result’s kind from t.table_type before applying the objectType
filter. Match that kind so “Views” returns views and “Tables” excludes them,
then reuse the derived kind for the result’s objectType.
- Line 93: Update the search collection flow in SchemaSearchStudio so table,
view, and namespace searches skip getTableDetail, and ensure every advertised
filter and constraint category produces results; otherwise remove unsupported
options and documentation claims, including the claims in SCHEMA_SEARCH.md. Add
namespace, unique, check, completeness, table-comment, and check-expression
handling only if retaining those advertised features.

Merge Risk: Moderate · up to 71135
Several new features do not work as described. The ER diagram shows tables without columns, some search filters return nothing, the dependency deep link ignores the requested table, and the table inspector can claim an immutable snapshot that was never loaded. These should be fixed or explicitly accepted before merge. Nothing here causes data loss or exposes data.
Security architecture risk: Low · up to 71135
The new views preserve the inspected server-side workspace authorization controls. A new relationship request allows URL-supplied schema identifiers to alter the intended API route, with a demonstrated routing and response-shape failure rather than unauthorized workspace access. Asynchronous relationship results also lack selection-identity guards, although cross-user exposure has not been established.
Retained concerns
Low · security · observed: The newly reachable schema-relationship client inserts a URL-derived schema identifier directly into an authenticated API path. Embedded route syntax can select a different relationship endpoint and violate the graph response contract. The traced alternate endpoint retains workspace authorization, so this is a bounded request-routing flaw rather than demonstrated unauthorized metadata access.
Security review details
Security Blast Radius
observed — The demonstrated path-manipulation outcome affects a credentialed GET to the configured API base and the caller's graph response contract. The traced schema-wide and table-specific relationship endpoints independently authorize workspace access. The evidence does not demonstrate cross-workspace access, credential disclosure, or gained write authority.
Security Findings and Attack Paths
observed — Both retained findings concern the new schema-relationship request path. URL-derived schemaId reaches raw path interpolation and fetch; a crafted identifier can select the table-relationships endpoint and return an incompatible response shape. The unit-test anchor uses mocked fetch to exercise that production method and does not establish a separate production sink.
Trust Boundaries and Controls
observed — The new table-inspector caller supplies its current workspace and URL-selected schema/table identifiers to the pre-existing table-detail API. That endpoint resolves the authorized workspace before looking up the schema and table, preserving server-side object ownership enforcement despite the new frontend reachability.
Resilience and Maintainability Implications
observed — The relationship loader retains graph state while requests run and renders its status independently of loading/error gates. This limits client-side context separation during reload and failure recovery even though server-side authorization is recomputed for each request.
Hardening Proposals
proposed — Apply consistent identifier-segment encoding to schema-wide relationship requests, matching the per-table relationship method, so identifiers cannot act as API route syntax.
proposed — Associate relationship-view state with a workspace/schema request generation, invalidate previous display state on identity changes, and accept success, error, and completion updates only from the current generation.

These three buttons switch the visible content on the same route. Give the container role="tablist". Give each button role="tab" and aria-selected. Give the content region role="tabpanel". Without this, assistive technology cannot report the active sub-view.

Update the ordering sub-tabs driven by orderingTab: mark their container as a
tablist, give each button tab semantics with aria-selected reflecting the active
tab, and mark the corresponding visible content region as a tabpanel.
These buttons switch the visible panel on the same route. A <nav> with plain buttons is therefore the wrong pattern. Screen readers receive no active-state information. The PR also claims WCAG 2.2 AA.
Use role="tablist" on the container. Give each button role="tab", aria-selected, aria-controls, and an id. Give the panel container role="tabpanel" and aria-labelledby.
Also add role="tabpanel", id={inspector-panel-${activeTab}}, and aria-labelledby={inspector-tab-${activeTab}} to the panel wrapper at Line 106.

Move the asserted logic into production code, or remove these tests.
These tests assert on fixtures declared in the same file. The "creation order" and "drop order" tests check a hand-written array and its reverse. The "search matching" tests run an inline filter on a local array. The only production imports are types.
No production code runs, so these tests cannot fail on a regression. The BFS and search logic lives inside React components (TransitiveReachabilityPanel, SchemaSearchStudio).
Extract pure helpers, such as computeReachability and a search matcher, and test those helpers.

Move orientation out of the loadGraphData dependencies.
orientation is in the dependency array. Toggling the orientation recreates loadGraphData, and the effect on line 208 then refetches the relationship graph and table list.
Each toggle therefore:
shows the loading skeleton,
clears selection,
resets the viewport,
discards manual node positions.
Fetching is only needed when the workspace or schema changes. Keep the fetched rawGraph and model in state. Run computeDeterministicLayout in a separate effect or handler that depends on orientation.

Remove orientation from the loadGraphData dependencies so workspace or schema
changes alone trigger fetching; keep rawGraph and the graph model in state, and
recompute layout separately when orientation changes using
computeDeterministicLayout.
Toggle buttons do not expose their state to assistive technology.
The view-mode, Filters, and Legend buttons show their on/off state only through the variant color. Screen reader users cannot tell whether the filter bar or legend is open. Add aria-pressed to the Filters and Legend buttons. The view-mode button already changes its visible label, so it is lower priority.

complete, or clearly notify users when results are truncated.
- Around line 61-64: Separate schema loading from namespace loading in the
component’s effects: load schemas only when the workspace changes, and load
namespaces keyed by the workspace and `filters.schemaId`. Clear namespace
options when `schemaId` is empty, and reset `filters.namespace` whenever the

Fix node column enrichment. It never produces columns.
apiClient.listTables returns TableSummaryItem[]. That type has column_count but no columns array. The local tableSummaries type (columns?: any[]) hides this, so matched?.columns is always undefined. Every node gets columns: [].
Effects:
Cards show "0 cols" and no PK/FK markers.
Card height is computed for zero columns.
Column-name search in the filter finds nothing.
The AccessibleGraphTable primary key column is always "None".
RelationshipDetails shows an empty column list.
limit: 100 also silently drops tables beyond 100 even if columns existed.
Fetch real column data. Options:
Call apiClient.getTableDetail for each node, in bounded batches.
Add a backend endpoint that returns columns with the relationship graph.
Map ColumnDetailItem to ColumnItem (is_foreign_key is computed in buildGraphModel). Remove the any[] cast.
The unit and component tests build columns by hand, so they do not catch this.

apps/web/src/components/er-diagram/layout.ts:310-313 Major · Functional Correctness · Quick win
Fix TB layout. Rank rows overlap when rank heights differ.
y is CANVAS_PADDING + r * (maxHeight + rankSeparation). maxHeight is the maximum height of the current rank only. The offset for rank r is not the sum of the previous ranks' heights.
Example: rank 0 has a 300px table and rank 1 has 100px tables. Rank 1 starts at 60 + 1 * (100 + 100) = 260. Rank 0 ends at 60 + 300 = 360. The cards overlap. Card heights vary with column count (up to 8 visible columns), so this is common.
Accumulate a running currentY across ranks.
Proposed fix
- sortedRanks.forEach((r) => {+ let rankY = CANVAS_PADDING;+ sortedRanks.forEach((r) => {
const bucket = rankBuckets.get(r)!;
let currentX = CANVAS_PADDING;
// Find max height in this rank for consistent Y spacing
const maxHeight = Math.max(...bucket.map((n) => n.height));
bucket.forEach((node) => {
- const y = CANVAS_PADDING + r * (maxHeight + options.rankSeparation);+ const y = rankY;
node.x = currentX;
node.y = y;
...
});
+ rankY += maxHeight + options.rankSeparation;
});
The sketch assumes the elided lines inside the bucket.forEach callback stay unchanged. The doc formula in ER_LAYOUT_ALGORITHMS.md for TB should then use a cumulative sum of rank heights.

Wire completeness and provenance fields before documenting these badges.
The relationship route renders GraphStatus without completeness or collectionTimestamp. GraphStatus therefore defaults to "complete" and omits the timestamp. A partial or restricted graph will appear complete, and the documented collection time never appears. Pass the selected schema metadata into GraphStatus, or narrow this specification.

Provide column data before documenting column search.
The relationship API returns nodes without columns, and the table-list API returns summaries with column_count, not columns. The relationship route then assigns columns: matched?.columns || [], so real graph nodes receive empty column lists. Column search and column rows therefore do not work. Extend the response contract or fetch table details before relying on this feature. (raw.githubusercontent.com)

These three buttons switch the visible content on the same route. Give the container role="tablist". Give each button role="tab" and aria-selected. Give the content region role="tabpanel". Without this, assistive technology cannot report the active sub-view.

Move the asserted logic into production code, or remove these tests.
These tests assert on fixtures declared in the same file. The "creation order" and "drop order" tests check a hand-written array and its reverse. The "search matching" tests run an inline filter on a local array. The only production imports are types.
No production code runs, so these tests cannot fail on a regression. The BFS and search logic lives inside React components (TransitiveReachabilityPanel, SchemaSearchStudio).
Extract pure helpers, such as computeReachability and a search matcher, and test those helpers.

Move orientation out of the loadGraphData dependencies.
orientation is in the dependency array. Toggling the orientation recreates loadGraphData, and the effect on line 208 then refetches the relationship graph and table list.
Each toggle therefore:
shows the loading skeleton,
clears selection,
resets the viewport,
discards manual node positions.
Fetching is only needed when the workspace or schema changes. Keep the fetched rawGraph and model in state. Run computeDeterministicLayout in a separate effect or handler that depends on orientation.

preserves exact correspondence only when `source_columns` and `target_columns`
have equal length; do not change the implementation.
Review comments at @docs/frontend/ER_DIAGRAM_ARCHITECTURE.md:
- Around line 37-40: Replace the “100% WCAG 2.2 AA” claim in the Accessible
Table View diagram with a qualified, audited status; do not imply full
compliance without verified evidence.
Review comments at @docs/frontend/ER_EDGE_RENDERING.md:
- Around line 34-35: Update the Hit Targets section to document that cross-table
edges use an 18px stroke while self-loop edges use a 16px stroke; keep the
documented values aligned with the behavior in RelationshipEdge.
Review comments at @docs/frontend/ER_INTERACTIONS.md:
- Line 20: Update the click handler in ERCanvas to treat clicks on the full-size
SVG background rectangle as deselection targets, alongside clicks on the
container or SVG, so the selected node or edge is cleared.
Review comments at @docs/frontend/ER_LAYOUT_ALGORITHMS.md:
- Around line 44-45: Update computeDeterministicLayout so each TB rank’s y
position accounts for the heights of all preceding ranks, using cumulative rank
offsets or a consistent global maximum height; ensure later ranks never overlap
earlier ones.
Review comments at @docs/frontend/ER_PERFORMANCE.md:
- Around line 13-14: Update the performance description to distinguish
buildGraphModel, which builds and sorts the model, from
computeDeterministicLayout, which calculates coordinates and bounds afterward.
Replace the O(V + E) claim with an accurate or measured bound that accounts for
node and edge sorting and queue.includes, and clarify that changing orientation
reloads and recomputes the graph rather than relying on the current caching
description.
Review comments at @docs/frontend/ER_TESTING.md:
- Line 22: Update the API Client bullet in the ER testing documentation to
describe that the unit tests verify the X-Workspace-Id header on mocked
requests; do not characterize this header check as authorization coverage.
Review comments at @docs/frontend/INSPECTOR_ACCESSIBILITY.md:
- Around line 28-29: Update the Search Studio and Table Tabs entries in
INSPECTOR_ACCESSIBILITY.md to remove the unsupported shortcut and arrow-key
claims, and describe only keyboard navigation actually available for the search
controls and inspector buttons.
Review comments at @docs/frontend/INSPECTOR_SECURITY.md:
- Line 49: Update the Graph Traversal Limits statement to say the maximum depth
is 999 hops, matching the full transitive traversal limit used by
TransitiveReachabilityPanel.
- Line 40: Update the “No Direct Database Connections” claim in
INSPECTOR_SECURITY.md to apply specifically to inspector responses, and describe
credential entry separately to acknowledge that the connection form holds the
entered database password in React state and sends it to the API.
- Around line 47-48: Update the Search Debouncing and Bounded Result Sets claims
to describe stale-result cleanup without claiming in-flight requests are
aborted, and clarify that pagination slices results after collection rather than
limiting collected results or backend requests; do not present these controls as
denial-of-service protection.
Review comments at @docs/frontend/INSPECTOR_TESTING.md:
- Around line 33-49: Update the test paths and commands in the documentation to
target the existing `inspector_and_dependencies.test.ts` files, and revise the
unit and component coverage lists to describe only tests and symbols actually
present in those files. Remove claims about `toInspectorObject()`, sorting, BFS
depth, execution ordering, `TableInspector`, `SearchStudio`, and
`DependencyExplorerStudio` where unsupported by the test files.
Review comments at @docs/frontend/SCHEMA_SEARCH.md:
- Around line 17-21: Update the searchable-entity and keyboard/request behavior
descriptions in the schema search documentation to match SchemaSearchStudio:
omit table comments, check expressions, and namespaces from searchable results,
and describe that stale request results are ignored rather than aborted and that
`/` does not focus the input.

Nitpick comments:
Review comments at @apps/web/src/app/(app)/relationships/page.tsx:
- Line 206: Remove orientation from the loadGraphData dependencies so workspace
or schema changes alone trigger fetching; keep rawGraph and the graph model in
state, and recompute layout separately when orientation changes using
computeDeterministicLayout.
Review comments at
@apps/web/src/components/dependency-explorer/DependencyExplorerStudio.tsx:
- Around line 118-137: Update the view switcher around views and activeView to
use ARIA tabs: give the nav a tablist role, each button a tab role with
aria-selected and aria-controls linked to its panel, and the corresponding panel
wrapper a tabpanel role with aria-labelledby linked to its tab. Follow the
existing pattern in TableInspector.
Review comments at
@apps/web/src/components/dependency-explorer/ExecutionOrderingPanel.tsx:
- Around line 27-61: Update the ordering sub-tabs driven by orderingTab: mark
their container as a tablist, give each button tab semantics with aria-selected
reflecting the active tab, and mark the corresponding visible content region as
a tabpanel.
Review comments at @apps/web/src/components/er-diagram/ERToolbar.tsx:
- Around line 56-63: Add aria-pressed to the Filters and Legend buttons in
ERToolbar, using showFilters and showLegend respectively so their expanded
states are exposed to assistive technology; leave the view-mode button
unchanged.
Review comments at @apps/web/src/components/table-inspector/TableInspector.tsx:
- Around line 72-79: Update the section switcher around tabs.map to use an
accessible tab pattern: make its container a tablist, and give each tab button
an id, tab role, aria-selected state from isActive, and aria-controls pointing
to its panel. Add the matching tabpanel role, id, and aria-labelledby to the
active panel wrapper, wired to activeTab.
Review comments at @apps/web/tests/unit/inspector_and_dependencies.test.ts:
- Around line 65-86: Update the creation-order, drop-order, and search-matching
tests to exercise production logic rather than hand-written fixture arrays and
inline filtering. Extract reusable pure helpers from TransitiveReachabilityPanel
and SchemaSearchStudio, then test those helpers; remove any assertions that only
verify fixture data.
