Summary

Implements DAG-based message ordering (Phases A+B from dev-docs/dag.md), replacing timestamp-based sorting with parentUuiduuid graph traversal. This is the foundation for proper resume/fork rendering (#85) and future async agent (#90) / teammate (#91) support.

Key capabilities added:

  • Structural message ordering via DAG traversal instead of fragile timestamp sorting
  • Hierarchical session navigation with parent/child relationships and backlinks
  • Within-session fork (rewind) visualization with branch pseudo-sessions
  • Robust handling of real-world JSONL quirks (compaction replays, progress gaps, tool-result side-branches)
  • Debug UUID toggle for DAG analysis

Changes by phase

Phase A — DAG Infrastructure (dag.py, 644 lines new)

  • MessageNode graph built from uuid/parentUuid links
  • extract_session_dag_lines() walks each session's chain, splitting at fork points into branch pseudo-sessions ({session_id}@{child_uuid[:12]})
  • build_session_tree() discovers parent/child session relationships from attachment points
  • traverse_session_tree() depth-first traversal producing render order
  • Junction point detection for forward/back navigation links
  • Heuristics for real-world data:
    • Compaction replay detection: same-timestamp children → follow first, skip replays
    • Tool-result stitching (2 variants): dead-end side-branches linearized
    • Progress gap repair: parent pointers rewritten to skip over skipped progress entries
    • Orphan promotion: dangling parentUuid → promoted to root (sidechain parents silently suppressed)

Phase B — Rendering Integration

  • converter.py: DAG-based loading in load_directory_transcripts() returns (messages, SessionTree) — tree is reused by the renderer to avoid rebuilding the DAG. Dedup fix for user text messages (use UUID as content key). Sidechain UUID scanning for false orphan suppression.
  • renderer.py: Session hierarchy extraction from pre-built tree, branch detection, render_session_id tracking, junction target propagation, branch-aware session navigation
  • models.py: is_branch / original_session_id on SessionDAGLine and SessionHeaderMessage
  • Templates: Branch/fork nav items, junction forward links, branch backlinks, debug UUID overlay
  • html/system_formatters.py: Branch-specific header formatting ("branched from" with context)

Cleanup

  • Removed dead code: has_cache_changes, extract_working_directories
  • Eliminated redundant DAG rebuild: _extract_session_hierarchy() now reuses the SessionTree built during loading instead of rebuilding from scratch

Test coverage

  • test/test_dag.py (1106 lines): Unit tests for DAG build, session extraction, fork detection, compaction replays, tool-result stitching, nested forks, orphan handling
  • test/test_dag_integration.py (710 lines): End-to-end tests with real JSONL data (sessions with forks, resumes, agent transcripts)
  • test/test_version_deduplication.py: Updated — user text messages with distinct UUIDs are no longer collapsed
  • Snapshot tests: Updated for new debug toggle and branch rendering
  • 4 new JSONL test fixtures: dag_simple.jsonl, dag_resume.jsonl, dag_fork.jsonl, dag_within_fork.jsonl
  • 2 real-project test sessions: Fork session 03eb5929, resume session a95fea4a

Diffstat

28 files changed, ~4500 insertions(+), ~250 deletions(-)

What's NOT in this PR (future phases)

  • Phase C: Agent transcript rework (DAG-line splicing instead of _reorder_sidechain_template_messages)
  • Phase D: Async agent (Support async agents #90) and teammate (Support "teammates" #91) support
  • UUID-based anchors for cross-session-page linking (documented in dev-docs/dag.md)

Test plan

  • just test — unit tests pass
  • just test-all — full suite including TUI
  • Visual check: uv run claude-code-log --clear-cache test/test_data/real_projects/-experiments-ideas/ — fork branches render correctly
  • Visual check on a project with frequent compaction — no spurious fork branches
  • ruff format && ruff check — clean

Note: Use --clear-cache for visual testing. The DAG changes affect how entries are ordered and grouped, so caches built by older versions will produce stale results (e.g., false orphan warnings). A breaking_changes entry should be added to cache.py when the version is bumped for release.

Closes #85 (DAG of Conversations — Phase A+B)
Relates to #79, #90, #91

578-580: Keep UUID references consistent when remapping UUIDs in fixtures.

Only uuid is rewritten; related reference fields (parentUuid, leafUuid) are left unchanged. That can create dangling links in test transcripts.

♻️ Suggested refactor pattern
 for session_id in ["session-1", "session-2"]:
+    uuid_map = {
+        e["uuid"]: f"{e['uuid']}-{session_id}"
+        for e in sample_jsonl_data
+        if "uuid" in e
+    }
     jsonl_file = project_dir / f"{session_id}.jsonl"
     with open(jsonl_file, "w") as f:
         for entry in sample_jsonl_data:
             entry_copy = entry.copy()
             if "sessionId" in entry_copy:
                 entry_copy["sessionId"] = session_id
-            if "uuid" in entry_copy:
-                entry_copy["uuid"] = f"{entry_copy['uuid']}-{session_id}"

1837-1839: Thread session_tree into renderer.generate_session() call at line 1863.

Line 1837 captures _tree but doesn't pass it to generate_session() at line 1863. Both parameters are already in scope. The generate_session() method accepts an optional session_tree parameter (see renderer.py:2656) to avoid redundant DAG reconstruction. The converter module (converter.py:1689) already follows this pattern—apply the same optimization here:

session_content = renderer.generate_session(
    messages,
    session_id,
    session_title,
    self.cache_manager,
    self.project_path,
    session_tree=_tree,

239-239: Remove quotes from font-family name for consistency.

The quoted font-family name 'SFMono-Regular' is inconsistent with standard CSS practices (unquoted font family names are preferred when not required). While the .stylelintrc.json configuration suggests this pattern, stylelint is not currently integrated into the CI/CD pipeline, so removing quotes would be for code consistency rather than fixing an enforced violation.

Suggested fix
-    font-family: 'SFMono-Regular', Consolas, monospace;
+    font-family: SFMono-Regular, Consolas, monospace;

Note: The same pattern appears in message_styles.css line 901 and should also be updated for consistency.

Inline comments:
In `@claude_code_log/converter.py`:
- Around line 140-144: The parent-chain traversal in converter.py (variables
parent, progress_chain, current) can loop forever on cycles; fix it by detecting
cycles with a visited set: in the while loop, track visited node ids and stop if
you encounter a node already visited, then set msg.parentUuid to None (or a safe
fallback) when a cycle is detected; otherwise, proceed to set msg.parentUuid =
current as now computed. Ensure you add the visited checks inside the loop that
assigns current = progress_chain[current] to prevent infinite loops.

In `@claude_code_log/dag.py`:
- Around line 168-180: The cycle detection loop currently only warns but leaves
cycles intact; modify the handler inside the loop so that when a cycle is
detected (current in visited) you both log and break the cycle by clearing the
offending parent link (e.g., set nodes[current].parent_uuid = None or
nodes.get(current).parent_uuid = None) so further parent-chain walks cannot loop
indefinitely; keep the logger.warning call and then mutate the node's
parent_uuid to None before breaking out of the while.
- Around line 475-476: The coverage check overcounts because walked_uuids and
skipped_uuids may overlap; replace the sum-based calculation with a union-based
distinct count (e.g., compute covered as the size of the set union of
walked_uuids and skipped_uuids) so duplicates aren't double-counted, ensuring
you convert to sets if those variables are lists; update the conditional that
compares covered to len(snodes) accordingly so missed nodes are detected
correctly.
- Around line 188-204: The recursive _collect_descendants function can overflow
on deep trees; replace its recursion with an iterative stack-based traversal
that preserves the same behavior: use a stack (e.g., list) seeded with uuid, pop
nodes in a loop, skip already-seen ids using result, add each visited id to
result, lookup node via nodes.get(uuid) and push its children_uuids onto the
stack only if they exist in session_uuids; ensure the checks for node None,
membership in session_uuids, and avoidance of duplicates remain identical to the
original logic to keep semantics unchanged.
- Around line 604-617: The child-session lists in children_at are iterated
unsorted, violating the docstring's chronological visitation guarantee; after
populating children_at (built from tree.sessions) sort each children_at[uuid] by
the session timestamp (e.g., tree.sessions[child_sid].created_at or .timestamp /
start_time field) so _visit_session is called in chronological order for each
uuid in dag_line.uuids; update the code that builds children_at to either insert
in sorted order or call sort(key=lambda sid: tree.sessions[sid].created_at)
(with the actual timestamp attribute used in SessionLine) before iterating.

In `@claude_code_log/html/system_formatters.py`:
- Around line 99-107: The code inserts content.original_session_id into HTML
unescaped (see content.original_session_id and orig_id variables) which can lead
to XSS; before slicing/assigning orig_id, escape the session id using the same
HTML-escaping utility used for escaped_title (e.g., html.escape or the module's
existing escape function), assign the escaped and then truncated value to
orig_id, and use that escaped orig_id in the return expression so no raw session
id is rendered into the link text.

In `@claude_code_log/html/templates/components/message_styles.css`:
- Line 901: Update the font-family declaration on the line containing
"font-family: 'SFMono-Regular', Consolas, 'Liberation Mono', Menlo, monospace;"
so it complies with stylelint: remove quotes around the single-token
SFMono-Regular and change the single-quoted Liberation Mono to use double quotes
(keep Consolas, Menlo and monospace unquoted); modify the font-family property
in the same CSS rule accordingly.

In `@claude_code_log/html/templates/components/session_nav.html`:
- Around line 15-28: The fork/branch nav items always use a hard href '#msg-d-{{
session.message_index }}' which breaks when the view is in mode="expandable";
update the session-nav-item rendering (the blocks using session.is_fork_point
and session.is_branch) to avoid emitting the dead href in expandable mode—use
the session or parent context flag (mode or is_expandable) to conditionally
render the anchor's href (or render a non-navigating element or data-attribute
like data-target instead) so links are only active when navigation by id is
supported; modify the anchor generation in those two blocks to check mode before
outputting href='#msg-d-{{ session.message_index }}' and keep the existing
classes (fork-link/branch-link) for styling/JS hooks.

In `@claude_code_log/renderer.py`:
- Around line 2006-2012: The current_render_session variable is being kept
across non-branch line starts, causing unrelated messages to be attributed to a
stale branch; update the logic that builds and consumes branch_start_uuids and
current_render_session so a non-branch start clears or switches
current_render_session to None (or the correct session) rather than retaining
the previous branch ID. Concretely: when iterating session_hierarchy to build
branch_start_uuids only map entries where hier.get("is_branch") is true (already
done) but when processing input lines (the code that looks up branch_start_uuids
and assigns current_render_session) add an explicit branch membership check and
set current_render_session = None if the line/start_uuid isn't in
branch_start_uuids or if the session_hierarchy entry is not a branch; ensure the
same reset logic is applied in the two places that assign current_render_session
so stale branch IDs cannot be reused for unrelated messages.
- Around line 639-644: The code adds junction_forward_links for branch_sids even
when ctx.session_first_message.get(branch_sid) returns None, causing broken
`#msg-d-None` links; update the loop in renderer.py (the branch_targets /
uuid_to_msg logic) to only append (branch_sid, branch_idx) to
fork_msg.junction_forward_links when branch_idx is not None (optionally log or
skip silently when missing) so no entries with None indices are emitted.

In `@dev-docs/dag.md`:
- Around line 70-88: The fenced example blocks showing the session topology,
session tree, rendered message sequence and the A(tool_...) examples should
include a language identifier to satisfy markdownlint MD040; update each
triple-backtick fence that currently has no language to use ```text (e.g., the
block containing "Session 1: a → b → c...", the block with "- Session 1 / -
Session 2...", the block with "s1, a, b, c...", and the A(tool_use...) example
blocks) and do the same for the additional similar blocks elsewhere in the file
so all non-code examples are fenced as ```text.
- Around line 43-45: The doc currently states that a non-linear parentUuid chain
within a session falls back to timestamp ordering; instead update the assertion
about session linearity to reflect the implemented behavior: when a
within-session branch (fork) occurs the system creates branch pseudo-sessions
for rewinds rather than simply falling back to timestamp ordering, and only uses
timestamp ordering when branch pseudo-sessions are not applicable; revise the
sentence mentioning parentUuid and "timestamp ordering within that session" to
explicitly mention branch pseudo-sessions for rewinds and clarify when timestamp
ordering is used, referencing the terms parentUuid, session, branch
pseudo-session, and rewind so readers can find the corresponding implementation
details.

In `@dev-docs/rendering-architecture.md`:
- Line 347: Update the DAG wording in dev-docs/rendering-architecture.md to
reflect that the DAG-based message architecture is now implemented and shipped
rather than a “planned replacement”: edit the sentence referencing [dag.md] (the
DAG-based message architecture) to state it is the current replacement for
timestamp ordering and briefly note it is deployed/active; ensure any phrasing
like “planned replacement” or future-tense is changed to present-tense and
optionally add a short pointer to dev-docs/dag.md for implementation details.

In `@test/test_dag.py`:
- Around line 26-44: The helper load_entries_from_jsonl claims to skip
unparseable lines but currently calls json.loads(...) and
create_transcript_entry(...) directly, which will raise and stop processing; fix
this by wrapping the parsing and entry creation in a try/except inside
load_entries_from_jsonl (around json.loads(line) and
create_transcript_entry(data)), catch JSONDecodeError/ValueError and errors from
create_transcript_entry (or a broad Exception if needed), optionally log the
error, and continue to the next line so malformed lines are skipped.

In
`@test/test_data/real_projects/-experiments-ideas/03eb5929-52b3-4b13-ada3-b93ae35806b8.jsonl`:
- Around line 2-61: The fixture contains hard-coded user/home paths and
identifiers (e.g. "/home/cboos/...") that must be redacted before committing.
Replace absolute paths and user names in the JSONL fixture entries with neutral
placeholders (for example "<REDACTED_HOME>" or "<USER>") wherever the string
"/home/cboos" appears and any occurrences of the username "cboos"; ensure
embedded tool outputs and file references (e.g. the Read tool result referencing
"work-and-dev-docs.md" and the stdout lines containing the absolute path) are
sanitized consistently so tests keep structure but no real user or filesystem
identifiers remain. Make the change in the JSONL fixture content and run the
test that loads this fixture to confirm parsing still works.

and _tree but _tree is not passed into renderer.generate_session; update the
renderer.generate_session invocation (the call that builds session_content) to
forward session_tree=_tree along with messages, session_id, session_title,
self.cache_manager and self.project_path so generate_session
(renderer.generate_session) can reuse the DAG instead of reconstructing it.

In `@test/test_cache_integration.py`:
- Around line 578-580: When remapping entry_copy["uuid"] to include session_id,
also update any related reference fields so links remain consistent: if keys
"parentUuid" or "leafUuid" exist in entry_copy, append the same "-{session_id}"
suffix to them (preserving their original values when absent), and do the same
in the other similar block (the similar code around the other occurrence).
Locate the code manipulating entry_copy and f.write (where entry_copy["uuid"] is
rewritten) and apply the same rewrite logic to parentUuid and leafUuid before
serializing.

Recursive descendant walk can overflow on deep branches.

Large/deep session trees can trigger RecursionError here. Use an iterative stack traversal.

In `@claude_code_log/dag.py` around lines 188 - 204, The recursive
_collect_descendants function can overflow on deep trees; replace its recursion
with an iterative stack-based traversal that preserves the same behavior: use a
stack (e.g., list) seeded with uuid, pop nodes in a loop, skip already-seen ids
using result, add each visited id to result, lookup node via nodes.get(uuid) and
push its children_uuids onto the stack only if they exist in session_uuids;
ensure the checks for node None, membership in session_uuids, and avoidance of
duplicates remain identical to the original logic to keep semantics unchanged.

Update the DAG status wording to reflect current implementation.

Line 347 still says DAG is a “planned replacement,” but this PR already ships that replacement. Please update the phrasing to avoid stale architecture docs.

load_entries_from_jsonl does not currently “skip unparseable lines” as documented.

json.loads(...) / create_transcript_entry(...) exceptions will terminate this helper instead of skipping malformed lines.

In practice, files end up in the wrong folder or never get moved, making the structure misleading rather than helpful.\n\n- **Fragmented context**: Understanding a feature often requires both its technical reference *and* its work history (decisions made, alternatives rejected).

Forcing them into a rigid two-tree structure mid-session interrupts flow, and retroactively sorting them is tedious busywork.\n\n- **Scales poorly with multiple contributors/actors**: When several actors (alice, bob, monk) generate documents concurrently, the `work/` subdirectory hierarchy (`archive/`, `backlog/`, `future/`, active) becomes a coordination bottleneck — everyone needs to agree on status transitions, and conflicts arise over what's \"active\" vs \"backlog\" vs \"done.\""}],"stop_reason":null,"stop_sequence":null,"usage":{"input_tokens":3,"cache_creation_input_tokens":2750,"cache_read_input_tokens":24675,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":2750},"output_tokens":9,"service_tier":"standard","inference_geo":"not_available"}},"requestId":"req_011CYCJ4kzMHiqbRgiFGuZQh","type":"assistant","uuid":"469c1506-89fc-47ae-934a-b6f569fd575e","timestamp":"2026-02-16T19:24:43.794Z"}

Design doc for replacing timestamp-based ordering with parentUuid graph
traversal. Covers session trees, junction points, agent transcript
splicing, and phased implementation plan (A-D). Foundation for #79,
#85, #90, #91.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
New dag.py module that builds a parentUuid→uuid graph from transcript
entries, replacing timestamp-based ordering with structural traversal.
Purely additive — no existing code modified.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Replace timestamp-based sorting in load_directory_transcripts() with
DAG traversal: partition sidechains, build DAG from main entries,
traverse depth-first, re-append summaries/queue-ops/sidechains.

Fix coverage bug in extract_session_dag_lines() where chain walk from
root only covers one node when all parentUuid values are null — now
falls back to timestamp sort when chain < total nodes.

…Phase B)

Build session hierarchy from DAG inside the renderer pipeline, enriching
SessionHeaderMessage and session nav with parent_session_id, depth, and
backlinks. Child sessions appear indented in the navigation and show
"continues from" labels in both the nav and session headers.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Backlinks in session headers and session nav are now <a href> links
that scroll to the parent session header. Uses d-{index} anchors which
are stable within the combined transcript (regenerated whole).

Also documents future UUID-based cross-page linking approach in
dev-docs/dag.md for when individual session pages need stable
cross-references.

Progress entries (type: "progress") carry UUID/parentUuid fields but are
skipped during parsing, creating gaps that make child entries appear as
orphans. Pre-scan JSONL files to collect progress uuid→parentUuid mappings,
then rewrite real entries' parentUuid to skip over progress gaps before
any DAG build.

Detect and render within-session forks where a user rewinds in Claude
Code, creating multiple same-session children from one parent node.
Branch pseudo-sessions use synthetic IDs ({session_id}@{child_uuid[:12]})
so existing session tree/junction/rendering machinery handles them.

Key changes:
- dag.py: _walk_session_with_forks() splits sessions at fork points into
  separate DAG-lines, with coverage fallback for degenerate cases
- renderer.py: branch detection moved before system message handling so
  system hooks are correctly assigned to their branch via _render_session_id
- Templates: lightweight fork-point/branch nav items, junction forward
  links at fork points, branch backlinks pointing to fork point message
- Models: is_branch/original_session_id on SessionDAGLine and
  SessionHeaderMessage

entry.sessionId is never mutated — only internal MessageNode.session_id
is updated for branch nodes, keeping cache/dedup/session files unaffected.

Branch nav items and headers now show the first user message text
instead of opaque IDs. Branch headers truncate at 80 chars for
readability.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Fork point nav shows parent message preview (walks past system hooks)
- Branch backlinks say "branched from" with fork point context
- Branch headers include original session ID for orientation

Context compaction replays created hundreds of false branch pseudo-sessions
(573 in clmail project) because replayed entries share the same parentUuid
but get new UUIDs. Tool-result entries from parallel tool calls also created
false forks by pointing back to their tool_use parent alongside the next
tool_use in the chain.

Two detection heuristics in _walk_session_with_forks():
- Compaction replays: same-timestamp children → follow first, skip rest
- Tool-result stitching: dead-end User + single Assistant continuation →
  stitch into linear chain

Also: orphan promotion (dangling parentUuid → root), multi-root walking
with trunk merging, and coverage tracking that excludes skipped replays.

Result on clmail project: 573 → 56 branches, 207 → 29 junction points.

Adds a small "uuid" button in the floating button stack that toggles

When an Assistant child's subtree eventually terminates while the User
child continues the main chain, stitch them linearly instead of creating

deduplicate_messages() used an empty content_key for user text messages,
collapsing distinct messages that shared the same timestamp. This dropped
DAG parent entries, causing false orphan warnings. Fix: use message.uuid
as the content key so only true duplicates (same UUID) are deduped.

…branches

Three improvements to the DAG rendering pipeline:

1. Suppress false orphan warnings for sidechain parents: scan UUIDs from
   unloaded subagent files (e.g. aprompt_suggestion agents) so progress-gap
   repair chains that land on sidechain entries don't trigger warnings.

2. Eliminate redundant DAG rebuild: load_directory_transcripts() now returns
   (messages, SessionTree) tuple; the tree is threaded through the entire
   render pipeline (converter → renderer → html/markdown renderers) so the
   DAG is built exactly once per run, including paginated pages.

3. Depth-based branch header indentation: branch headers use inline
   margin-left based on their tree depth instead of a fixed 2em, making
   nested fork structure visually apparent.

generate_session() and _generate_individual_session_files() were not
passing the pre-built SessionTree, causing the fallback DAG rebuild

CodeRabbit items considered and intentionally not changed:

#8 (dag.md fenced blocks): No language identifiers on non-code blocks
    — project convention, not using markdownlint.

#10 (dag.py:204 recursive → iterative): Max recursion depth is bounded
    by session message count. Python's default limit (1000) is more than
    sufficient for any real conversation.

#11 (converter.py:463 queue ops at tail): Queue operations are metadata
    entries, not user-visible conversation content. Appending at tail is
    the intended behavior.

#12 (renderer.py:2012 current_render_session leak): By design — branch
    context applies to all subsequent messages until the next line start.
    The variable is reset when a new DAG-line starts.

#13 (session_nav.html:28 fork rows in expandable mode): Non-issue.
    Fork/branch nav items only appear in ToC mode (combined transcript
    and individual session pages). Expandable mode is only used in the
    project index page where fork items wouldn't be generated. Verified
    that individual session pages DO correctly include fork/branch nav.

#14 (message_styles.css:901 font quoting): Cosmetic stylelint preference,
    no stylelint configured in this project.

#15 (test_dag.py:44 error handling): Test helper — should fail loudly on
    bad test data, not silently skip.

session_tree can become stale after filtering/dedup but is still reused for rendering.

In `@claude_code_log/converter.py` around lines 1142 - 1145, The session_tree is
built before messages are filtered/deduped and thus becomes stale; after calling
filter_messages_by_date and deduplicate_messages you must rebuild/update
session_tree from the new messages list before passing it into any render paths.
Locate where session_tree is initially constructed (the variable named
session_tree) and move or duplicate that construction to occur after messages =

ensure all downstream render calls use the rebuilt session_tree; apply the same

check used at the message attribution sites) so every DAG-line start (not just
branches) updates the context used by the later attribution logic.

In `@test/test_dag.py`:
- Around line 26-44: The loader load_entries_from_jsonl currently calls
json.loads and create_transcript_entry directly, which can raise and abort
processing; wrap the per-line parsing and entry creation in a try/except that
catches JSONDecodeError and any exceptions from create_transcript_entry, log or
ignore the malformed line, and continue to the next line so the function honors
its “skip unparseable” contract; reference load_entries_from_jsonl, json.loads,
and create_transcript_entry to locate where to add the try/except.

Nitpick comments:
In `@claude_code_log/html/templates/transcript.html`:
- Line 181: The debug toggle button currently only changes visual state; add
accessibility by initializing aria-pressed="false" on the <button
id="toggleDebug" class="debug-toggle"> and update the click handler that toggles
the visual state to also toggle aria-pressed between "true" and "false" (mirror
the CSS/state change). Apply the same change for the other debug button(s) with
class "debug-toggle" (lines ~199-203): ensure each has an initial aria-pressed
value and that their event handlers set aria-pressed consistently when toggling.

In `@claude_code_log/tui.py`:
- Around line 1837-1839: The code calls load_directory_transcripts(... ) and
receives both messages and _tree but then drops _tree and later rebuilds the
SessionTree inside generate_session/export/view flows; update calls to
generate_session (and the equivalent calls around the other block at lines
1863-1869) to accept and use the already-loaded _tree instead of reconstructing
it—i.e., change the signature/usage so generate_session (or whichever function
builds the DAG) takes the provided _tree from load_directory_transcripts and
uses it for session output/export/view paths to avoid redundant DAG
reconstruction.

In `@test/__snapshots__/test_snapshot_html.ambr`:
- Around line 5580-5589: The UUID toggle button handling in the DOMContentLoaded
listener needs a null check and accessible state management: ensure the element
fetched by document.getElementById('toggleDebug') (debugButton) is guarded
before use, and initialize/maintain its toggle state via the aria-pressed
attribute (e.g., set a boolean state, update aria-pressed on click, and reflect
initial state on load) so the toggle is resilient across template variants;
update the event hookup logic in the DOMContentLoaded handler that references
toggleDebug/debugButton to bail out if debugButton is null and to always
read/write aria-pressed when toggling.

In `@test/test_cache_integration.py`:
- Around line 575-580: The test fixture rewriting updates entry_copy["uuid"] but
leaves related UUID fields (e.g., "leafUuid") unchanged, breaking DAG
references; when you detect and rewrite entry_copy["uuid"] to include
session_id, also find and rewrite any related fields that reference UUIDs (for
example keys like "leafUuid", "parentUuid", "childUuid" or any key ending with
"Uuid") by appending or substituting the same session_id pattern so references
remain consistent; apply this change in the block handling entry_copy (the code
around entry_copy = entry.copy() and the subsequent session_id/uuid handling)
and replicate the same update in the similar block later (the one referenced
around lines 714-719).

Pass session_tree from load_directory_transcripts() to
generate_template_messages() so the pre-built tree reuse path
is exercised in tests, not just the DAG rebuild fallback.

The changes are quite significant, and I won't "commit" on those until I've given more testing (and maybe a closer look at the code); but for the testing to be "solid" I need to advance to the next phases C and D (#90, #91), as well as checking how #96 would work on top of that... but not in this PR. So, expect more PRs on top of this one!

In the meantime, review welcome ;-)
