136-163: buildArgsWithJSON allocation size warning is a false positive.The
len(args)+1capacity calculation is safe—CLI argument counts are OS-bounded (typically a few thousand max). CodeQL flags this theoretically but it's not exploitable in practice.
551-571: buildPlanArgs and buildDestroyPlanArgs allocation warnings are false positives.Same reasoning as line 146—CLI argument counts are bounded.

cmd/terraform/options_test.go (1)
36-53: Consider adding UI flag test coverage.The test cases don't yet cover the new
UIandUIFlagSetfields. You might want to add a test case that validatesv.Set("ui", true)results inopts.UI == true, and a separate test with a mock command to verifyUIFlagSetbehavior.pkg/terraform/ui/confirm.go (1)
36-55: Consider extracting a shared helper to reduce duplication.Both
ConfirmApplyandConfirmDestroyhave identical logic differing only by the title string. A shared helper would reduce maintenance burden.🔎 Proposed refactor

596-675: Consider extracting workspace options construction.The
ExecuteOptionssetup for workspace select (lines 597-607) and workspace new (lines 641-651) are nearly identical, differing only inArgs. A helper could reduce duplication, though this is minor.🔎 Optional: Extract helper
func buildWorkspaceOpts(info *schema.ConfigAndStacksInfo, componentPath string, action string, workspace string) *tfui.ExecuteOptions { return &tfui.ExecuteOptions{ Command: info.Command, Args: []string{"workspace", action, workspace}, WorkingDir: componentPath, Env: info.ComponentEnvList, Component: info.FinalComponent, Stack: info.Stack, SubCommand: "workspace", Workspace: workspace, DryRun: info.DryRun, } }pkg/terraform/ui/tree_test.go (1)
113-128: sortChildren test covers basic sorting but misses recursive case.The test validates top-level sorting. Consider adding a test case with nested children to verify
sortChildrensorts recursively if that's expected behavior.🔎 Optional: Add recursive sorting test
func TestSortChildren_Recursive(t *testing.T) { root := &TreeNode{ Address: "root", Children: []*TreeNode{ { Address: "z_resource", Children: []*TreeNode{ {Address: "z_child"}, {Address: "a_child"}, }, }, {Address: "a_resource"}, }, } sortChildren(root) assert.Equal(t, "a_resource", root.Children[0].Address) assert.Equal(t, "z_resource", root.Children[1].Address) // Verify nested children are also sorted. assert.Equal(t, "a_child", root.Children[1].Children[0].Address) assert.Equal(t, "z_child", root.Children[1].Children[1].Address) }pkg/terraform/ui/executor_test.go (1)
103-120: ExecuteOptions test is somewhat tautological.This test only verifies that struct field assignment works, which Go guarantees. Consider testing actual behavior that uses ExecuteOptions instead, or remove if there's no meaningful behavior to validate.
pkg/terraform/ui/model.go (2)
28-44: Unusedreaderfield in Model struct.The
readeris passed toNewParserin the constructor and stored inm.reader, but it's never used after that. The parser owns the reader.🔎 Remove unused field
type Model struct { tracker *ResourceTracker parser *Parser - reader io.Reader spinner spinner.Model progress progress.Model width intAnd in NewModel:
return &Model{ tracker: NewResourceTracker(), parser: NewParser(reader), - reader: reader, spinner: s,
247-268: Consider consolidating action verb formatting.
formatActivityVerb,formatActionPending,formatActionInProgress, andformatActionCompleteall map the same actions to slightly different verb forms. A single lookup table or helper could reduce duplication.🔎 Consolidated approach
var actionVerbs = map[string]struct { pending, inProgress, complete string }{ "create": {"Create", "Creating", "Created"}, "read": {"Read", "Reading", "Read"}, "update": {"Update", "Updating", "Updated"}, "delete": {"Destroy", "Destroying", "Destroyed"}, "no-op": {"No change", "No change", "No change"}, } func getActionVerb(action string, form int) string { if v, ok := actionVerbs[action]; ok { switch form { case 0: return v.pending case 1: return v.inProgress case 2: return v.complete } } return action }Also applies to: 325-377
pkg/terraform/ui/resource_test.go (1)
306-339: Concurrency test has a subtle address collision issue.The expression
string(rune('0'+n%10))produces only 10 unique addresses (test_0throughtest_9) for 50 goroutines. This means resources are overwritten rather than added, making the final count unpredictable. If the intent is stress-testing concurrent writes to the same keys, that's valid—but the assertionassert.Greater(t, rt.GetTotalCount(), 0)is weak. If the intent is 50 unique resources, fix the address generation.Option: Use unique addresses per goroutine
go func(n int) { rt.HandleMessage(&PlannedChangeMessage{ Change: PlannedChange{ - Resource: ResourceAddr{Addr: "aws_instance.test_" + string(rune('0'+n%10))}, + Resource: ResourceAddr{Addr: fmt.Sprintf("aws_instance.test_%d", n)}, Action: "create", }, }) done <- true }(i)This would require adding
"fmt"to imports and would result in 50 unique resources.pkg/terraform/ui/parser.go (1)
34-56: Consider iterative empty-line skip instead of recursion.The recursive
p.Next()call on line 47 works fine in practice, but deeply malformed input with many consecutive empty lines could cause stack growth. A loop would be more robust.Iterative approach
func (p *Parser) Next() (*ParseResult, error) { + for { if !p.scanner.Scan() { if err := p.scanner.Err(); err != nil { return nil, err } return nil, io.EOF } line := p.scanner.Bytes() if len(line) == 0 { - // Skip empty lines. - return p.Next() + continue } msg, err := p.parseMessage(line) return &ParseResult{ Message: msg, Raw: append([]byte{}, line...), // Copy to avoid scanner reuse. Err: err, }, nil + } }pkg/terraform/ui/resource.go (1)
202-207: GetChangeSummary and GetOutputs return internal pointers.Unlike
GetResourcesandGetDiagnostics, these return pointers to internal state without copying. If callers mutate the returned structs, it could corrupt tracker state. Consider returning copies or documenting as read-only.Return copies for safety
func (rt *ResourceTracker) GetChangeSummary() *ChangeSummaryMessage { rt.mu.RLock() defer rt.mu.RUnlock() + if rt.changeSummary == nil { + return nil + } + copy := *rt.changeSummary - return rt.changeSummary + return © }Also applies to: 304-309

136-163: Solid argument construction logic.The function correctly handles the -json flag insertion. The static analysis overflow warning on line 146 is a theoretical concern - CLI argument slices are bounded by practical limits.
551-598: Argument transformation logic is correct.Both functions properly convert between command types and handle flag filtering. The static analysis overflow warnings (lines 553, 580) are low-risk given CLI argument constraints.

31-162: Consider adding performance tracking to public functions.All public functions in this file are missing
defer perf.Track()calls. Per coding guidelines, public functions should include performance tracking.Based on coding guidelines, public functions should have performance tracking.
cmd/terraform/workspace.go (1)
44-45: Consider updating the comment for consistency.The call site is correct, but the comment on line 44 is generic. For consistency with
apply.goanddeploy.go, consider updating it to mention the command context purpose:- // Parse base terraform options. + // Parse base terraform options with command context for UI flag detection. opts := ParseTerraformRunOptions(v, cmd)pkg/terraform/ui/confirm.go (2)
14-33: Missingperf.Track()on public functions.Per coding guidelines, public functions should include performance tracking. Consider adding:
func ConfirmApply() (bool, error) { + defer perf.Track(nil, "ui.ConfirmApply")() + var confirm boolSame applies to
ConfirmDestroy().
35-55: Consider extracting shared confirmation logic.Both
ConfirmApplyandConfirmDestroyshare identical structure. A private helper could reduce duplication:🔎 Optional refactor
func confirmPrompt(title string) (bool, error) { defer perf.Track(nil, "ui.confirmPrompt")() var confirm bool theme := uiutils.NewAtmosHuhTheme() prompt := huh.NewConfirm(). Title(title). Affirmative("Yes"). Negative("No"). Value(&confirm). WithButtonAlignment(lipgloss.Left).

9-15: Test doesn't validate intended behavior.This test expects
falsebecause it runs in CI. The comment acknowledges this limitation. Consider either:
- Mocking
telemetry.IsCI()andterm.IsTTYSupportForStdout()to test the positive case- Removing this test if it can't validate the expected behavior
As-is, it only confirms CI auto-disables the feature, not that explicit enable works.
103-120: Tautological test - consider removal.This test only verifies that struct field assignment works. Per coding guidelines, avoid tautological tests that test language mechanics rather than behavior.
internal/exec/terraform.go (1)
588-681: Consider extracting workspace streaming helper to reduce duplication.The streaming patterns for workspace select (lines 596-631) and workspace new (lines 640-675) are nearly identical. A helper function could consolidate this:
🔎 Optional refactor
func executeWorkspaceWithStreaming( useStreaming bool, atmosConfig schema.AtmosConfiguration, info *schema.ConfigAndStacksInfo, args []string, componentPath string, redirectStdErr string, ) error { if useStreaming { opts := &tfui.ExecuteOptions{ Command: info.Command, Args: args, WorkingDir: componentPath, Env: info.ComponentEnvList, Component: info.FinalComponent, Stack: info.Stack, SubCommand: "workspace", Workspace: info.TerraformWorkspace, DryRun: info.DryRun, } err := tfui.ExecuteInit(context.Background(), opts) if !errors.Is(err, errUtils.ErrStreamingNotSupported) { return err } } return ExecuteShellCommand( atmosConfig, info.Command, args, componentPath, info.ComponentEnvList, info.DryRun, redirectStdErr, ) }pkg/terraform/ui/parser.go (1)
16-25: Missingperf.Track()on public function.Per coding guidelines, public functions should include performance tracking:
func NewParser(r io.Reader) *Parser { + defer perf.Track(nil, "ui.NewParser")() + scanner := bufio.NewScanner(r)pkg/terraform/ui/init_model.go (1)
54-70: Missingperf.Track()on public constructor.func NewInitModel(component, stack, subCommand, workspace string, reader io.Reader) *InitModel { + defer perf.Track(nil, "ui.NewInitModel")() + // Use MiniDot spinner for init/workspace (more subtle, different from plan/apply).pkg/terraform/ui/tree.go (3)
55-71: Missingperf.Track()on public function.Per coding guidelines:
func BuildDependencyTree(ctx context.Context, planfilePath, terraformPath, workingDir, stack, component string) (*DependencyTree, error) { + defer perf.Track(nil, "ui.BuildDependencyTree")() + // Run terraform show -json planfile.Also consider capturing stderr for better error diagnostics:
- output, err := cmd.Output() + output, err := cmd.Output() if err != nil { - return nil, fmt.Errorf("failed to run terraform show: %w", err) + var exitErr *exec.ExitError + if errors.As(err, &exitErr) && len(exitErr.Stderr) > 0 { + return nil, fmt.Errorf("failed to run terraform show: %w: %s", err, string(exitErr.Stderr)) + } + return nil, fmt.Errorf("failed to run terraform show: %w", err) }
253-268: Missingperf.Track()on public method.func (t *DependencyTree) RenderTree() string { + defer perf.Track(nil, "ui.DependencyTree.RenderTree")() + var b strings.Builder
786-803: Consider usingstrconv.ParseIntfor hex parsing.The manual parsing works but
strconv.ParseInt(hex, 16, 64)is simpler and handles edge cases:🔎 Optional simplification
func parseHexComponent(hex string) (int64, error) { - var result int64 - for _, c := range hex { - result *= 16 - switch { - case c >= '0' && c <= '9': - result += int64(c - '0') - case c >= 'a' && c <= 'f': - result += int64(c - 'a' + 10) - case c >= 'A' && c <= 'F': - result += int64(c - 'A' + 10) - default: - return 0, fmt.Errorf("%w: invalid hex character: %c", errUtils.ErrParseHexColor, c) - } - } - return result, nil + result, err := strconv.ParseInt(hex, 16, 64) + if err != nil { + return 0, fmt.Errorf("%w: %v", errUtils.ErrParseHexColor, err) + } + return result, nil }pkg/terraform/ui/executor.go (4)
113-116: Type assertion could panic if model type changes.The assertion
finalModel.(Model)will panic ifp.Run()returns an unexpected type. Consider using the comma-ok idiom for defensive coding.Suggested fix
- m := finalModel.(Model) - if m.GetError() != nil { - return m.GetError() + m, ok := finalModel.(Model) + if !ok { + return fmt.Errorf("unexpected model type from TUI: %T", finalModel) + } + if m.GetError() != nil { + return m.GetError() }
288-291: Same type assertion pattern - apply consistent fix.Same issue as in
Execute()- use comma-ok idiom for safety.Suggested fix
- m := finalModel.(InitModel) - if m.GetError() != nil { - return m.GetError() + m, ok := finalModel.(InitModel) + if !ok { + return fmt.Errorf("unexpected model type from TUI: %T", finalModel) + } + if m.GetError() != nil { + return m.GetError() }
632-641: Consider using CommandContext for timeout safety.
exec.Commandwithout context could hang indefinitely ifterraform outputblocks. Since this is called in the success path, a hung process would freeze the UI.Suggested fix
-func fetchAndDisplayOutputs(command, workingDir string) { +func fetchAndDisplayOutputs(ctx context.Context, command, workingDir string) { // Run terraform output -json to get current outputs. - cmd := exec.Command(command, "output", "-json") + // Use a timeout context to prevent hanging on unresponsive terraform. + timeoutCtx, cancel := context.WithTimeout(ctx, 30*time.Second) + defer cancel() + cmd := exec.CommandContext(timeoutCtx, command, "output", "-json") cmd.Dir = workingDirThen update call sites to pass the context.
1-26: File organization is acceptable.The file is slightly over the 600-line guideline, but functions are cohesive. Consider extracting output display logic (lines 600-815) to a separate file like
outputs.goin a future refactor if the file grows further.

Learning: In cmd subpackages (e.g., cmd/terraform/backend/), tests cannot use cmd.NewTestKit(t) due to Go's test visibility rules (NewTestKit is in a parent package test file). These tests only need TestKit if they execute commands through RootCmd or modify RootCmd state. Structural tests that only verify command structure/flags without touching RootCmd don't require TestKit cleanup.

Learning: In Go, package-level declarations (constants, variables, types, and functions) are visible to all files in the same package without imports. During reviews in cloudposse/atmos (and similar Go codebases), before suggesting to declare a new identifier, first check if it already exists in another file of the same package. If it exists, you can avoid adding a new declaration; if not, proceed with a proper package-level declaration.

Learning: For terraform apply interactivity checks in Atmos (internal/exec/terraform.go), use stdin TTY detection (e.g., `IsTTYSupportForStdin()` or checking `os.Stdin`) to determine if user prompts are possible. This is distinct from stdout/stderr TTY checks used for output display (like TUI rendering). User input requires stdin to be a TTY; output display requires stdout/stderr to be a TTY.

Learning: In Atmos, when calling cfg.InitCliConfig, you must first populate the schema.ConfigAndStacksInfo struct with global flag values using flags.ParseGlobalFlags(cmd, v) rather than passing an empty struct. The LoadConfig function (pkg/config/load.go) reads config selection fields (AtmosConfigFilesFromArg, AtmosConfigDirsFromArg, BasePath, ProfilesFromArg) directly from the ConfigAndStacksInfo struct, NOT from Viper. Passing an empty struct causes config selection flags (--base-path, --config, --config-path, --profile) to be silently ignored. Correct pattern: parse flags → populate struct → call InitCliConfig. See cmd/terraform/plan_diff.go for reference implementation.

Instead, document the OpenTofu requirement in code comments and documentation, trusting users who enable the feature (e.g., `PassVars`) to ensure their terraform command points to an OpenTofu binary.

pkg/terraform/ui/tree_test.go (4)
11-32: Good table-driven test structure for action symbols.Clean use of table-driven testing as per guidelines. The test correctly validates that colored output contains expected symbols across all action types including the composite "replace" action.
34-54: Simple tree rendering test looks solid.Covers the essential checks: header rendering, resource presence, and tree connector characters.
90-132: Good coverage for change summary including replace semantics.Both tests validate that
GetChangeSummarycorrectly counts actions, with the second test confirming that "replace" increments both add and remove counters. This aligns with Terraform's semantics.
188-263: Comprehensive extractReferences test cases.Table-driven tests cover key scenarios: simple references, module-qualified references, prefix handling, filtering of var/local references, and nil expression handling. This directly validates the fix for the module-qualified reference extraction logic flagged in previous reviews.
pkg/terraform/ui/parser.go (3)
15-25: Appropriate buffer sizing for Terraform JSON.The 1MB buffer handles large JSON lines well. Good practice to use scanner.Buffer() to prevent token-too-long errors with complex Terraform plans.
36-59: Iterative approach correctly avoids stack overflow.The loop-based empty line skipping addresses the previous review concern about tail recursion. The raw bytes copy (
append([]byte{}, line...)) properly prevents issues from scanner buffer reuse.
71-166: Clean type dispatch pattern.The switch handles all defined message types with consistent unmarshaling. Unknown types gracefully fall back to BaseMessage. Structure is maintainable for adding new message types.
pkg/terraform/ui/init_model.go (4)
54-71: Well-structured model initialization.Uses theme colors from
pkg/ui/theme/colors.goas required. MiniDot spinner provides subtle visual feedback appropriate for init operations.
111-129: Clean message handling with ANSI stripping.Properly strips ANSI codes to prevent display corruption. The operation tracking and viewport management logic is straightforward and maintainable.
174-181: Rune-aware truncation correctly implemented.Using
runewidth.StringWidthandrunewidth.Truncateproperly handles multi-byte UTF-8 characters. This addresses the previous review concern about byte-based slicing.
217-234: Edge case in formatAction for empty subCommand.The default case at line 229-232 could panic if
m.subCommandis empty, thoughstrings.ToUpper(m.subCommand[:1])on an empty string would cause an index out of range. Thelen > 0check protects this, but returning the empty string seems odd.Consider whether an empty subCommand is a valid state that should be handled differently or logged.

1-244: Comprehensive PRD documentation.Well-structured documentation covering problem statement, solution design, configuration options, and implementation details. The supported commands list now correctly includes
destroy. Good alignment with the implementation.pkg/terraform/ui/tree.go (5)
56-71: External command execution without timeout.
BuildDependencyTreeusesexec.CommandContextbut relies solely on the passed context for timeout. If the caller doesn't set a deadline,terraform showcould hang indefinitely.Verify that callers always pass a context with appropriate timeout, or consider adding a local deadline.
88-101: Composite action handling looks correct.The logic properly identifies replace operations (len == 2) and single actions. This addresses the previous review about missing composite action detection.
216-260: Module-qualified reference extraction now handles nested modules.The updated logic correctly extracts resource addresses from module-qualified references and applies prefixes appropriately. This addresses the previous critical review about dependency graph corruption.
772-816: WCAG-compliant contrast calculation.Clean implementation of relative luminance formula for accessibility. Using 0.5 threshold provides good contrast for badge text.
818-835: Custom hex parsing uses static error.Good use of
errUtils.ErrParseHexColorfor error wrapping, following the coding guidelines for static errors.pkg/terraform/ui/executor.go (6)
43-59: Appropriate TTY and CI environment checks.The early checks for TTY support and CI environment align with the streaming UI design. DryRun bypass is clean.
68-80: Stderr passes through correctly.Passing stderr directly to
os.Stderrallows terraform warnings and prompts to display normally. This is the right approach for interactive flows.
136-164: Argument building avoids integer overflow.Using
appendfor capacity growth as noted in comments prevents the overflow concerns from previous static analysis hints.
196-212: Planfile cleanup on error path.The temp planfile is properly removed on both error and success paths. Good resource management.
320-354: ShouldUseStreamingUI logic is clear and correct.Decision flow: explicit flag override → config check → CI auto-disable → TTY check → subcommand filter. Note that "refresh" is explicitly disabled due to poor JSON streaming support.
635-677: Silent error handling for terraform output fetch.
fetchAndDisplayOutputssilently ignores errors, which is appropriate here since outputs may not exist yet. The function is used for informational display only.pkg/terraform/ui/types.go (5)
1-9: Clear package documentation.Package comment explains the purpose well: streaming TUI for Terraform operations with Docker-build-style interface.
10-29: Comprehensive message type coverage.Constants cover all Terraform machine-readable UI message types. Including
MessageTypeResourceDriftis forward-looking for drift detection scenarios.
227-242: Trailing periods now present on comments.All inline field comments end with periods, addressing the previous review concern about godot linter compliance.
197-225: ResourceState enum with String() method.Clean implementation with explicit handling for unknown states. The String() method is useful for logging and debugging.
244-275: Phase enum follows same pattern.Consistent with ResourceState implementation. Both enums provide clear string representations.

56-71: Add performance tracking and use static errors.Per coding guidelines, public functions should include
defer perf.Track(atmosConfig, "pkg.FuncName")()(usenilif noatmosConfigparam). Additionally, errors at lines 62 and 67 should wrap static errors fromerrors/errors.gorather than using plainfmt.Errorfwith string messages.Based on coding guidelines: "All errors MUST be wrapped using static errors defined in errors/errors.go" and "Add defer perf.Track to all public functions."
🔎 Example pattern
func BuildDependencyTree(ctx context.Context, planfilePath, terraformPath, workingDir, stack, component string) (*DependencyTree, error) { + defer perf.Track(nil, "ui.BuildDependencyTree")() + // Run terraform show -json planfile. cmd := exec.CommandContext(ctx, terraformPath, "show", "-json", planfilePath) cmd.Dir = workingDir output, err := cmd.Output() if err != nil { - return nil, fmt.Errorf("failed to run terraform show: %w", err) + return nil, fmt.Errorf("%w: failed to run terraform show: %w", errUtils.ErrRunTerraformShow, err) } var plan tfjson.Plan if err := json.Unmarshal(output, &plan); err != nil { - return nil, fmt.Errorf("failed to parse plan JSON: %w", err) + return nil, fmt.Errorf("%w: failed to parse plan JSON: %w", errUtils.ErrParsePlanJSON, err) } return buildTreeFromPlan(&plan, stack, component) }Note:

Learning: For terraform apply interactivity checks in Atmos (internal/exec/terraform.go), use stdin TTY detection (e.g., `IsTTYSupportForStdin()` or checking `os.Stdin`) to determine if user prompts are possible. This is distinct from stdout/stderr TTY checks used for output display (like TUI rendering). User input requires stdin to be a TTY; output display requires stdout/stderr to be a TTY.

Learning: In Go, package-level declarations (constants, variables, types, and functions) are visible to all files in the same package without imports. During reviews in cloudposse/atmos (and similar Go codebases), before suggesting to declare a new identifier, first check if it already exists in another file of the same package. If it exists, you can avoid adding a new declaration; if not, proceed with a proper package-level declaration.

Learning: In Atmos (internal/exec/terraform.go), when adding OpenTofu-specific flags like `--var-file` for `init`, do not gate them based on command name (e.g., checking if `info.Command == "tofu"` or `info.Command == "opentofu"`) because command names don't reliably indicate the actual binary being executed (symlinks, aliases). Instead, document the OpenTofu requirement in code comments and documentation, trusting users who enable the feature (e.g., `PassVars`) to ensure their terraform command points to an OpenTofu binary.

14-14: Clean addition of the refresh icon.The new
IconRefreshconstant follows the existing pattern with proper documentation. The "↻" symbol is semantically appropriate for indicating replace/recreate operations, and it's actively used in the streaming UI tree rendering.pkg/terraform/ui/tree_test.go (1)
11-263: Comprehensive test coverage with good structure.The test suite effectively covers the key functionality with table-driven tests and behavior-focused assertions. Tests for
colorizedActionSymbol, tree rendering, change summaries, sorting, and reference extraction all follow the coding guidelines well.Note: Error cases for
BuildDependencyTree(exec failures, JSON parse errors) aren't covered, but since those require mockingexec.CommandContext, they're better suited for integration tests or would require dependency injection.
…reaming-ui # Conflicts: # NOTICE # website/package.json # website/pnpm-lock.yaml
…own deploy-ui cast The streaming UI's dependency tree is built per-component from a single plan file (pkg/terraform/ui/tree_builder.go), showing resource addresses and actions — not a cross-component dependency graph. Reword to say "resource dependency tree" to avoid the ambiguity. Also drop the deploy-ui.cast blog embed to speed=0.3 (from the 0.6 default): the underlying recording only captures ~4.3s of real terminal activity, so even the default slowdown plays too fast to follow. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…ter model The streaming UI's dependency tree rendered with broken rails: attribute-diff rows blanked the ancestor rails to spaces, nothing carried a rail from a node down to its first child through those rows, and count/for_each resources were flattened to the root because config-level dependencies (base addresses) never matched their instance-keyed plan addresses in either direction. Move the gutter geometry into pkg/ui/tree: Connector/ContentGutter/SpacerGutter are pure functions of a node's Path, and Violations checks the invariant that every box-drawing character has a rail or its parent's connector directly above it. A 500-tree property test covers the model; tree_render asserts the real renderer satisfies it in compact and non-compact modes. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…rogress block Bubbletea repositions to the top of the previous frame before writing the done-state view, so the model's own cursor-up loop climbed 2+N rows above the block, wiping the typed command, init/workspace lines and prior output, and left the summary stranded with a blank tail. Erase to end of screen from the frame top instead. CastPlayer's erase-below now drops the rows like a real terminal rather than keeping blank scrollback, which is what made the player auto-scroll to nothing at the end of a recording. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…ith real timing Replace the single null_resource deploy-ui cast (0.65s of real activity, no tree to show) with a dedicated demo/casts/fixtures/streaming-ui fixture: a null_resource + time_sleep VPC (vpc, subnets, route table associations) with genuine create/destroy delays, recorded through plan, apply and destroy in one cast so all three --ui paths are shown.

scanner.Text() line before passing it to log.Debug, ensuring Terraform stderr
secrets are protected even when logging directly to os.Stderr.
In `@pkg/terraform/ui/tree_builder.go`:
- Around line 328-332: Update the nested-module address construction in the
moduleCount branch of populateTreeNodes so it consumes all module.<name> pairs
and retains the following resource type and resource name when present; ensure
references such as module.network.module.vpc.aws_subnet.main.id resolve to the
module and resource address expected by resolveDependencyNode instead of a
module-only address.
- Around line 141-143: Update stripInstanceKey to remove bracketed instance
selectors from every address segment while preserving the complete module and
resource path, so buildRelationships can match normalized dependency keys for
count or for_each modules. Add coverage for an instanced module address and
retain unselected address segments unchanged.
In `@pkg/terraform/ui/tree_render.go`:
- Around line 520-527: Update makeTruncator to measure and slice strings by
runes rather than byte indices, preserving the existing width and ellipsis
behavior. Replace the duplicated truncation logic in renderMultilineValueSimple
with the shared makeTruncator helper so both truncation sites handle UTF-8
safely.

Nitpick comments:
In `@cmd/terraform/subcommands_test.go`:
- Line 470: Consolidate the duplicated three-case `--ui` propagation setup from
TestWorkspacePassthroughLeafPropagatesUIFlag and
TestDestroyCommandPropagatesUIFlag into one shared test helper accepting t, the
command, and the extra parser; have both tests call the helper while preserving
the existing true, false, and omitted flag cases.
In `@pkg/scheduler/adapters/terraform_test.go`:
- Around line 1794-1803: Refactor TestValidateTerraformUIConcurrency into a
table-driven test containing both streaming UI scenarios, with each case
specifying the input and expected error outcome. Iterate over the cases as
subtests, preserving the existing ErrInvalidConfig and message assertions for
true and the no-error assertion for false.
In `@pkg/terraform/ui/executor_args.go`:
- Around line 147-169: Extract the shared argument-conversion loop from
buildPlanArgs and buildDestroyPlanArgs into one helper that accepts the
index-zero replacement token(s). Preserve skipping flagAutoApprove, retaining
all other arguments, and appending the plan output flag, while having both
functions supply their respective replacement values.
In `@pkg/terraform/ui/model_diagnostics_test.go`:
- Around line 18-26: Extract the repeated log-capture setup in the affected
tests into a shared helper that returns the bytes.Buffer and registers cleanup.
Have the helper save both the original log output and level, then restore those
exact values during cleanup instead of unconditionally using os.Stderr; update
each affected test to use the helper.
In `@pkg/ui/tree/gutter_test.go`:
- Around line 52-54: Convert TestSpacerGutter into a table-driven test with
named input Path values and expected spacer strings, then iterate over the cases
and assert SpacerGutter for each one so failures identify the scenario.

- Truncate long attribute lines by rune, not byte, so multi-byte UTF-8 is never split mid-character. - Strip instance keys on module segments too (module.x["k"].type.name) when resolving dependencies, and keep the trailing resource type/name of a nested-module reference instead of collapsing it to the module path. - Don't mistake the value of a value-taking apply flag (-var, -lock-timeout, ...) for a trailing positional plan file. - Reap a killed terraform process after a TUI failure so it isn't left a zombie with its pipes open, and mask terraform stderr before logging it, since the logger bypasses the masking writer when no log file is set. - Pin CI=true in the dispatch tests so the streaming precondition gate is deterministic regardless of the runner's TTY. - Schema: max_lines minimum 0; note destroy among the supported commands. - Doc touch-ups (fenced block languages, skill path).

… trees are connected The stacks/instances trees add spacer rows as marker-titled lipgloss child nodes and then replaced each rendered marker row by counting its leading spaces and emitting a single bar. That dropped every ancestor rail of a nested spacer (the ones between a stack's components), breaking the gutter. Replace it with pkg/ui/tree.SpacerFromConnectorRow, which keeps the ancestor rails and turns the node's own connector into a rail. Teach Violations to recognize lipgloss/tree's three-column enumerator arm alongside this package's four-column segments, and assert the stacks, instances and dependencies trees satisfy the connectivity invariant, with a regression for the nested spacer.

lipgloss.Width(line) can exceed maxWidth while len([]rune(line)) is still less than maxWidth-3 for wide (e.g. CJK) characters, which occupy two cells per rune - slicing the rune slice at maxWidth-3 in that case indexes past its end and panics.

…lease The earlier security-remediate commit (f6fbd20) replaced `secrets: inherit` with an explicit secrets map on the reusable-workflow calls in test.yml, nightlybuilds.yml, feature-release.yml, and build.yml. Neither callee (cloudposse/.github's shared-go-auto-release.yml or shared-release-branches.yml) declares a `workflow_call.secrets:` schema -- only `inputs:` -- so GitHub rejects a named-secret map against them outright. This surfaced on the PR as the "Tests" and "Feature release" workflows both failing with startup_failure ("likely failed because of a workflow file issue"), with zero jobs ever created -- the whole test suite silently stopped running. build.yml has the identical shape but only triggers on release/workflow_dispatch, so it hadn't failed yet on this PR, just hadn't run at all. Revert all four back to `secrets: inherit`, which is the only valid way to pass secrets to a reusable workflow that doesn't declare named secret inputs.

feature-release.yml runs on pull_request by design: it publishes a prerelease binary for a PR a maintainer has labeled release/feature, so the shared workflow checks out the PR head and signs/publishes with the release secrets. Add an explicit same-repository guard on the job. pull_request already withholds repository secrets from fork PRs, but this makes that boundary explicit in the workflow itself and keeps a labeled fork PR from starting the job at all instead of failing partway through with empty secrets. Document why the trigger is pull_request and why the secrets can't be narrowed: the callee declares no workflow_call.secrets schema, so an explicit secrets map is rejected at startup (the earlier attempt was reverted in ec0cc09). Addresses the CodeRabbit finding on the secrets: inherit line. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
… drop shard-1 override Measured over 378 successful Windows shard jobs across 38 main runs (2026-08-19..09-02): whole job p50 14.8m / p95 27.4m / max 44.5m, and the "Acceptance tests" step p50 6.8m / p95 18.8m / max 30.1m. 50/40 clears both maxima with headroom. The old 65/55 budgets bought nothing: the only Windows jobs that ever ran past ~45m were ones whose steps had all finished and passed, after which the runner's end-of-job results upload stalled indefinitely (the job's log blob is never received), and in the same sample no job ever stalled after "Complete job" and then recovered. A larger budget only decides how long a dead job holds the run before failing it. Drop the shard-1 override (65/60 on every platform): per-shard maxima are linux 16.3m / macos 19.8m / windows 31.1m, all inside the flavor budgets, and shard 3 -- not shard 1 -- is the slow one on Windows. Left in place, it would have kept a hung Windows shard-1 job at the old budget. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
