…orpus Records the full-residency survey (what the cache already answers, the four hard parts refined, the global couplings beyond them, and a staged path), the provider coverage check (codex/agy bypass the fragment store and render pool entirely), and clarifies that every --all-projects timing uses the 8-largest-by-trunk-bytes subset of downloads/projects, not the full corpus.

memory_capped_workers applies even to a pinned RENDER_JOBS, so a sweep row could claim a fan-out width that never ran. Compute the effective count with the converter's own formula (a pinned count is not clamped to the CPU count, only to memory) and label capped rows as e.g. 'both (64->48 workers)'.

Streaming stage 2 (work/render-format-once.md): when the cache is fresh, the combined output current, and only session files stale, load only the files holding those sessions' entries and render them through the unchanged per-session pass — byte-identical to the full path, verified on two coupling-heavy real archives (85 and 187 output files identical; 64 and 129 sessions regenerated partially) and pinned by fixture + synthetic tests with the full loader monkeypatched to raise. Three pieces make the partial load faithful: - A cross-session sidecar (migration 008), persisted by every full unfiltered load from the tree it already built: per-session parent linkage, junction points with ordered targets, and the dedup winner for every uuid carried by more than one session. The partial load enforces winners up front, patches parent/junction facts whose other end isn't loaded, and adds empty ancestor stub lines for depth. - Discovery via the cache's messages table (get_session_file_map), not filename stems — real archives have files whose entries span two sessions and sessions with no file of their own. Archived stale sessions are skipped outright (the full path loads everything and still renders nothing for them). - A pagination-aware combined-freshness check: the Phase-1b gate used to ask after combined_transcripts.html, a name paginated projects have no cache row for, so they never early-exited and full-loaded on every direct conversion even when fully current. The check now replays the pagination plan from cached session data alone, which also makes the plain early exit fire for paginated projects. Measured on the 8-core VM against the 803MB reference archive, warm cache: one stale session 4.6s -> 0.6s (7.9x); a fully-fresh direct conversion -> 0.4s. CLAUDE_CODE_LOG_SESSION_SCOPED=0 disables the path for bisecting; every decline falls back to the full load unchanged. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
application_model.md gains § 2.12 (mechanism, sidecar, fidelity bar, measurements) plus the migration-list and cache-subsystem updates; CONTRIBUTING points at the bisecting knob; the render-format-once diary records phase 8 — including the three things the implementation surfaced: sessionId->file is not 1:1 in real archives, paginated projects never reached the Phase-1b early exit at all, and archived-stale sessions pinned projects to the slow path forever. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Streaming stage 3 (work/render-format-once.md): when a paginated HTML
project's combined output is stale and available memory is under 2.4x
the project's transcript bytes (the same knee where the fragment store
declines — CLAUDE_CODE_LOG_STREAMING=1 forces, =0 kills), the
conversion no longer loads the whole project. It plans the session→page
assignment from cached session data alone, then per page needing work
loads only the files holding that page's sessions through the stage-2
partial-load machinery, renders the page and its stale session files
together against a per-page fragment store, and drops it all before
the next page. Peak residency becomes one page, not the archive:
measured on the 8-core/16GB VM, a full rebuild of the 803MB reference
archive went 1490MB → 591MB peak RSS at slightly lower wall
(28.2s → 25.2s), byte-identical across 187 output files; the 296MB
document-processing project 454MB → 305MB across 85 files.
ensure_fresh_cache now persists the cross-session sidecar too, so a
run whose cache was just refreshed streams instead of loading the
project a second time. Every decline — missing sidecar, any page
session with an incomplete source-file set (strict resolution) —
falls through to the unchanged full path.
Two correctness traps found and pinned on the way:
- The sidecar recorded *branch-qualified* dedup winners
("{trunk}@{uuid12}", the id branch splitting stamps onto tree
nodes), which match no raw entry.sessionId — so partial loads
dropped every copy of such uuids, silently deleting whole branches
from partially-rendered sessions. A latent stage-2 bug, caught by
this phase's hash runs. Winners are now the surviving entry's raw
sessionId, with a load-side normalization so sidecars written by
the buggy code still enforce correctly
(test_session_scoped_render.py::TestBranchWinnerMechanics).
- A page load can carry a partially-loaded co-resident session from
another page (a source file spanning two sessions), which the
session pass would render truncated — and its cache row would then
read current forever. The per-page session pass is restricted to
the page's own stale sessions
(test_streaming_render.py::TestFileSpanningSessions pins it; the
mutation reproduces the truncation).

application_model.md § 2.13 (the as-built reference: gating, the memory-valve ladder, the two load-bearing correctness details), CONTRIBUTING's knob note, and the diary's phase-9 entry with the measurements and the branch-winner post-mortem. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Single-project mode now benchmarks the page-granular streaming pass alongside the memo/fan-out rows (on paginated projects), adds an incremental scenario — page 1 + a few session files stale, the daily-run shape — and reports each configuration's peak RSS via a getrusage(RUSAGE_CHILDREN) wrapper, since streaming is precisely a wall-vs-residency trade. Every row now pins CLAUDE_CODE_LOG_STREAMING explicitly: on a memory-tight machine auto mode would otherwise stream under the full-path labels. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Answering "if streaming is faster anyway, should we always use it?": no — but the memory valve was leaving wins on the table. Benchmarked against a 137MB/26-page archive on the 8-core VM (the comparison phase 9 never ran: streaming vs the *parallel* full path), a full rebuild belongs to the fan-out (6.7s vs streaming's 11.1s), but the incremental daily-run shape streams faster than the fan-out — 2.0s vs 3.3s — at half the peak RSS and less total CPU, because a couple of page loads replace the whole-project load that dominates such runs. So auto mode on a roomy (or unmeasurable-memory) machine now runs the streaming pass in sparse mode: it plans its pages, counts the ones needing work (cache/stat queries only — the staleness scan moved out of the render loop into a pre-pass), and declines itself past 1/3 of the plan, a margin under the measured ~36% crossover, falling through to the full load + fan-out. Force and memory-tight modes are unchanged, as is the kill switch. Pinned in TestSparseGate (sparse streams with the full loader forbidden; dense declines; a stale session pulls its page into the count); docs updated in CONTRIBUTING, application_model § 2.13, and the diary's phase-10 entry. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The streaming/fan-out sweep in bench_render.py needs a paginated archive above the fan-out's 25k-message floor, which not every machine has lying around; this generates one from any real project (bijective UUID rotation + requestId suffixing per copy, so copies never collide or dedup together). Referenced from the diary's phase-10 entry instead of a session-scratchpad path that would orphan. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Both reference archives re-measured with the extended bench (byte- identical across all configurations), auto-mode spot checks on real copies and inside hierarchy runs, the crossover bracket, and the pre-existing hierarchy-planner gap found along the way (a manually deleted non-first page alone is not detected as staleness).

Survey-grounded (identities I1-I3 hold across the full 78-project corpus; cross-session distinct-uuid requestIds ~never occur): closure fixpoint over modified files, re-election exemptions, junction merge semantics, delta aggregates over hidden-flagged session rows, and the decline ladder. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The last full-residency step: one changed file made ensure_fresh_cache re-walk every file to recompute session rows, project aggregates and the sidecar. It now recomputes all three from a bounded coupling closure of the modified files — dedup partners of their uuids, attachment-point owners, the complete old target list of any junction they touch, and the sessions their summaries/ai-titles name — loaded through the stage-2/3 partial-load machinery with two refresh-mode deviations (modified uuids re-elect natively; touched junctions keep their locally built target list instead of the stale sidecar row). Two migrations make the aggregate delta exact. 009 persists warmup-only and empty sessions as hidden rows, so every session's contribution is on record while the visible set stays byte-identical. 010 adds residual_count — entries a session owns that compute_session_data skips — counted from the *traversed* list, because attachments are parsed into the cache yet can be dropped by DAG traversal, so cached row counts over-count the project total. Both columns decline (rather than guess) on rows written before them. Anything hairy declines to the unchanged full refresh: deleted files, rewritten history, cross-boundary token attribution, strict-resolution gaps, closures past a third of the project. Measured on the 803MB archive, first conversion after three new sessions: 1131MB -> 582MB peak RSS at 10.6s -> 6.7s. With the render already streaming, the refresh's full load was the peak — so the pipeline now scales with what changed, not with the archive. Verified by DB-state equivalence (session rows incl. hidden, aggregates, all three sidecar tables) plus rendered byte-identity: 15 tests, holdback runs on four real archives, an in-place upgrade from a pre-009 cache, and the total-count identity re-checked across all 78 corpus projects.

Measured a 0.26s backwards jump in a 4-second sample while time.monotonic() advanced normally, which explains an mtime-assertion test that flakes ~1 run in 6 and the occasional negative duration in CLI output. Unrelated to this branch (reproduced with every knob disabled); the real fix is time.monotonic() for elapsed measurements, left for a separate change. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The dev box's wall clock is not monotonic (a 0.26s backwards jump measured inside a 4-second sample, guest clock sync), which made the CLI print negative per-project durations and made seven "was it regenerated?" mtime assertions flake. Every production duration now reads time.monotonic(): the eight elapsed sites in converter.py plus renderer_timings.py, renderer.py and html/renderer.py — those three share a clock domain through log_timing(t_start=...), so they had to move together, and its docstring now states the reading must be monotonic. Genuine timestamps (cache.py's datetime.now() rows, the mtime freshness compare) stay on time.time(). File mtimes come from the OS, so monotonic can't fix those assertions; they move to conftest.assert_regenerated, which compares for *change* rather than "later" — what the call sites mean, and what survives a clock that can step backwards. It sits beside bump_mtime, whose comment block already documents the sibling filesystem-clock flake. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The fan-out's batch gate required 8 units, on the premise that "units average well under 200ms". That holds for session units — cheap, because the page pass already put their fragments in the store — and not at all for page units, which carry ~page_size messages each and are where nearly all of a conversion's render time lives. So a project with fewer than 8 pages (~16k messages at the default page size) rendered its expensive page batch inline and fanned out only its cheap session batch: it paid the pool's ~1s of spawn + import for the batch with the least to gain. _worth_dispatching weighs the batch instead: a lone unit never dispatches (it would render in a worker while the parent waits); once the pool has started, any multi-unit batch does, since the startup is sunk — which is how the session batch rides along behind the page batch that paid for it; otherwise the batch must carry _MIN_ENTRIES_FOR_RENDER_POOL (4,000) worth of entries, twice what that startup costs at the render phase's measured throughput. Measured on 16 real projects, full rebuild off a warm cache, every configuration byte-identical: projects between 4k and 15k messages went from 0.86-1.05x to 1.27-2.27x, and projects below the gate went from 0.82-0.94x — the count gate fanning out a batch with nothing to gain — back to 1.00x. Archive-level scenarios are unchanged (full rebuild 1.13x, incremental 3.43x), since a full rebuild's core split already grants one render worker per project. _MIN_MESSAGES_FOR_RENDER_POOL follows the gate down to the same number and becomes a pure short-circuit: every batch is a subset of the project's message list, so a project below the gate cannot form a batch that clears it. The hold-back's eligibility floor was reading that constant and is now its own _MIN_MESSAGES_FOR_HOLDBACK (25,000, unchanged in effect) — _fanned_speedup promises 2.5x at 8+ workers, which a 3-page project does not deliver, and over-estimating there serializes a project that was better off pooled. Closes the § 7.5 threshold revisit: memory_capped_workers needed nothing (re-measured, project-to-project variance exceeds any drift) and per_project_render_jobs is unchanged.

`pytest -m browser` — the parallel default, and what `just ci` runs — reaches ~93% and stops dead with zero CPU in both pytest and Chromium, so `just ci` never returns. `-n0` runs the same 90 tests green in 75s. Reproduced at the pre-change commit, so it is environmental rather than anything on this branch; recorded with the workaround so the next session doesn't spend an hour rediscovering it.

"Top-level *.jsonl, excluding agent- sidecars" was written out at eight call sites — four of them the identical byte sum that every memory heuristic is calibrated against (the render pool's worker cap, the fragment-store valve, the streaming valve, a plan's source_bytes). They are now utils.trunk_jsonl_files / project_transcript_bytes. That also fixes a drift the duplication had already allowed: scripts/bench_render.py computed the same quantity *without* the agent- exclusion, so its memory preview and its "both (N->M workers)" labels predicted a cap the converter would not apply — 16 of the 79 corpus projects carry top-level agent files, one inflating its measured size by 30%. It now calls the shared helper, so the harness and the code it benchmarks cannot disagree again. The benchmark's 8-project reference subset is unchanged (same projects, largest still 329MB); only its quoted total moves, 1539MB -> 1493MB, and the diary says so. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The fragment store and the streaming path each carried their own 2.4x constant, each documented as deliberately the *same* knee "so the ladder is continuous". Two constants that must move together will eventually drift — exactly what had already happened with the transcript-byte sum the previous commit consolidated — so they are now one `_MIN_AVAILABLE_MEMORY_PER_TRANSCRIPT_BYTE`, with the derivation stated once and both consumers listed under it. No behaviour change: same number, same two comparisons. Also drops a stale comment block above the fragment-store valve. It was the justification for `_MIN_MESSAGES_FOR_RENDER_POOL = 25_000`, orphaned from its constant by an earlier insertion and left behind when the batch gate replaced it; its conclusion (crossover between 15.5k and 25.2k) now contradicts the measurements above `_MIN_ENTRIES_FOR_RENDER_POOL`, and `_MIN_MESSAGES_FOR_RENDER_POOL` has carried its own comment since.

`just ci` could sit forever. A browser-suite run under xdist was observed stopping dead at ~93% with zero CPU accumulation in both pytest and Chromium, and it stayed there for 75+ minutes before being killed — which reads as "still running", not as a failure, so the suite has no way to report it and nothing records which test was stuck. pytest-timeout with a 300s per-test ceiling turns that into a normal failure. Nothing in the suite is remotely near it (slowest measured: 5.6s browser, 4.5s otherwise), so it only ever fires on the pathological case. `thread` rather than the default `signal` method, because SIGALRM only lands while the main thread is running Python and so cannot break a hang inside a C extension or a blocked driver pipe — the shape of hang worth catching. Under xdist the killed worker surfaces as `worker 'gwN' crashed while running <nodeid>`, which names the test; re-run that one with `-n0` for the thread dump. Doesn't fix the hang itself — it has not reproduced since (six clean xdist browser runs, including at -n 16 and with available memory squeezed to 2.8GB, plus a full green `just ci`) so there is nothing to bisect. This makes the next occurrence self-reporting. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Three passes have to agree on it — `convert_jsonl_to`'s `use_pagination`, which makes the real decision; the Phase-1b staleness replay in `_combined_output_is_stale`; and the Phase-1c streaming gate — and all three spelled the rule out inline. The latter two exist precisely to predict what the pagination pass will do without loading the project, so a drift between the three copies would surface as pages silently not regenerating: exactly the coupling `_plan_page` was factored out to protect, one level up. `_is_paginated` states it once, including why the page-count clause is there (an already-paginated project stays paginated when its message count drops back under `page_size`, rather than stranding the pages it has). Callers still source the counts themselves, since they read them from a cache row, a loaded message list, or both. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Phase 1b and Phase 1c were ~165 lines of inline gate-and-dispatch in the
middle of a 610-line function, and they have the identical shape — check
preconditions, attempt a path that avoids loading the project, return or
fall through. That shape is this branch's central contract, so it is now
stated once in a section comment and expressed twice as a signature:
`_try_current_or_session_scoped(...) -> Optional[Path]` and
`_try_streaming(...) -> Optional[Path]`, where None means "did nothing,
try the next path" and a Path means "handled it".
Both blocks kept their nested conditionals as early returns, which is
what makes the decline paths readable: the invariant that a decline must
be indistinguishable from never having been attempted (no output
written, `report` untouched) is now checkable per branch instead of by
tracing indentation.
Phase 1b stays one function rather than two despite covering two
outcomes ("nothing is stale" and "only session files are stale"): they
share the preconditions and both staleness queries, so splitting would
run `_combined_output_is_stale` and `get_stale_sessions` twice.
Pure extraction. Verified beyond the suite on a real 13-session,
2-page project, running fresh convert -> changed-file convert ->
no-op convert -> deleted-session convert, which fires all three partial
paths (streaming, all-current early exit, session-scoped): every output
byte-identical before and after.

`converter.py` is five modules in one file, and the fan-out glue is the seam that comes away cleanest: `_make_render_pool`, `_worth_dispatching` and `_dispatch_render_units` have no back-edges into the rest of the converter, and both thresholds they read exist only for them. They now live in `render_dispatch.py` as `build_render_pool`, `worth_dispatching` and `dispatch_render_units`. Not inside `render_pool.py`, which they are about: that module is the mechanism — what a worker is, what crosses the process boundary, how many workers memory allows — and deliberately knows nothing about projects, transcripts or pages. What moved is the conversion-side policy, and it reads exactly those things. Keeping it a layer above also keeps the dependency one-way, so a worker process never imports the policy it is executing, and avoids a `make_render_pool` / `_make_render_pool` pair in one namespace. converter.py loses ~230 lines. Tests that reached the thresholds and gates through `converter.` now reach them through `render_dispatch.`; the cross-references in `fragment_store.py`, `render_pool.py` and dev-docs § 2.10 follow, and § 2.10 gains the module split plus a row in the subsystem table. No behaviour change: the same real-project sequence used for the previous commit (fresh -> changed-file -> no-op -> deleted-session convert over a 13-session, 2-page project) is byte-identical to the pre-refactor baseline. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`process_projects_hierarchy` runs each project either inline or in a pool worker, and the argument set for `convert_jsonl_to` was written out separately for each: the inline call, the `pool.submit` payload dict, and `_convert_project_worker`'s unpacking of that dict back into a call. Three copies of one signature, so adding a parameter to `convert_jsonl_to` meant remembering all three — and forgetting one would not fail, it would make pooled projects convert differently from inline ones, silently and only under `--jobs > 1`. `_conversion_kwargs(plan, silent=, render_jobs=)` builds it once. The inline path applies it, the pool ships the same dict, and the worker just does `convert_jsonl_to(**worker_args)` — it no longer knows the signature at all. It's a closure rather than a module-level function because it reads a dozen of the hierarchy call's own parameters, which a module-level version would only re-list. Paths now cross the process boundary as `Path`, not `str` (they pickle fine); the two per-path notes that were attached to the copies — workers always run silent, render_jobs is the parent-computed nested-pool share — moved to where the values are set. Verified on three real projects converted as a hierarchy: `--jobs 4` with the render fan-out on produces output byte-identical to `--jobs 1` with it off, across all 31 files.

The xdist browser hang entry stood as an open environmental problem with a `-n0` workaround. It has stopped reproducing — six clean parallel runs including `-n 16` and one under a memory squeeze, plus a full green `just ci` — so the entry now says what was seen, what was ruled out, and that the standing suspect (conftest's shared persistent Chromium context) was never confirmed. It also records what replaced the workaround: a hang is now a test failure, not a stalled suite. Adds § 8 for the structural review of `converter.py`: what landed, and what was deferred with the reason. The deferrals matter more than the list — splitting `process_projects_hierarchy` wants a conversion-request parameter object sweeping five call sites, which is a design change rather than a refactor, and doing half of it would be worse than none.

In `@CONTRIBUTING.md`:
- Around line 304-318: Update the streaming guarantee in the documented
paginated conversion flow: clarify that CLAUDE_CODE_LOG_STREAMING=1 bypasses
only the memory and sparse gates, while conversion still requires the paginated
HTML path, a resolvable page, and sufficient memory for the largest page’s
source files. Replace the unconditional “any machine, any staleness” and “no
archive is too big” claims with wording that states these limits.

overwrite earlier ones. Either derive the UUID rotation from the full copy index
or explicitly reject copy counts above 16 while preserving unique session
identity.
- Around line 54-56: Update the destination validation before dst.mkdir in the

Impressive! Makes me wonder if, once we have that in, we could even consider an incremental rendering mode (a continuation of your idea of a ccl server, but that would also render the HTML of a session as it grows) |

Thanks 😸 first I thought updating a modified session's HTML and was going to say that should already work, but then I realised probably what you mean is to do a full pipeline streaming update so if you run this watch mode, the HTML in the page would get updated real-time with SSE or something? |

Yes, that's what I meant. Since .jsonl is append-only, if you have rendered one session "up to a point", it should be easy to ingest new messages by remembering the length corresponding to the last read, then seeking to that position and reading the newly added lines. The tricky part, of course, is properly updating the data structures we have: given the multiple passes, making the updates incremental is not trivial. And once we have the updated messages, rendering just the delta and injecting that into the right place(s) (plural, as it's a tree) would also be challenging. If we did that for the currently loaded sessions, it would enable a "live update" effect. However, the usefulness of such a feature is largely mitigated now by the fact that if you enable |

This branch has solved most of the incremental challenges to make streaming work, we have some more metadata written in the cache db to make it possible to save the data structures too. That was the only way to prevent having to load entire projects and sessions in memory and reparse for every change. I wasn't sure if all this added complexity was worth it (especially as the union of people doing agentic coding and very memory constrained devices is probably not huge), but sounds like we'll be able to do some cool new features like this so I'm more positive about it! I've gone pretty much sandbox only with agents and also a bit uneasy about Anthropic streaming all my local sessions by default, so no I'm just finishing this up, wanted to do one more round of adversarial review, please hold #316 as it will need to mesh into this refactored pipeline. |

I was annoyed by the fact that the library is unbounded by RAM usage when it comes to the single biggest project archive so set Claude on implementing streaming conversion, but this work also got us some performance gains elsewhere.
In Claude's own words:
