Claude Code deletes its transcripts after ~30 days, so between one run and
the next a day can go from fully sourced to PARTIALLY sourced. On such a
day the daily cache re-derives a smaller slice from the surviving files
and that slice REPLACES the baseline one rather than being unioned with
it, so the aged-out portion is lost. A day that aged out completely is
carried forward correctly, which is what makes this a hole in never-lose
rather than a missing feature.
The check ages the corpus the way retention does: two days keep a single
anchoring transcript each, a third loses every one. It then compares the
(date, provider) slices in daily-cache.v19.json against the ones the
0.9.20 baseline recorded in daily-cache.v17.json, requiring the partial
days never to shrink and the fully sourceless day to come back exactly.
This is a hard failure, not a note. It is expected to be red until the
fix lands: on the generated corpus the two partial days currently lose
76.6% and 56.8% of their cost, while the fully sourceless control day
returns to the cent.
It runs last and on its own cache dir, so mutating the corpus cannot
disturb the payload parity comparison. The shard-republication defect
found earlier stays a note, now naming its pending follow-up issue.
Everyone upgrading from the last published CLI crosses the session-cache
v7 -> v9 re-layout (#1005/#1007) and the daily-cache v17 -> v19
re-derivation (#1015) on their first run. That path was covered by unit
tests on one platform against caches the tests wrote themselves.
`npm run verify:upgrade` (and the matching matrix job over
{ubuntu, windows, macos} x node {22.13.0, 22}) instead installs the real
codeburn@0.9.20 into an isolated global prefix, points it at a generated
seven-provider corpus in a HOME whose path contains a space, and lets it
write a genuine session-cache.v7.json + daily-cache.v17.json. This build
then runs against that same cache dir, installed the same way, so
dist/parse-worker.js has to resolve from an entry point outside the
checkout.
It asserts the v7 file is retired, the v9 envelope and shards publish,
the daily history does not shrink, and per-provider calls/tokens/cost
match the baseline exactly for claude, codex, gemini, kiro and cursor.
grok is reported rather than asserted (its accounting changed in #1015)
and dsh is required to be new. It also smoke-tests serve --stdio against
the one-shot payloads, pins CODEBURN_PARSE_WORKERS to 0 and 3 and
requires identical shards and payloads either way, and checks that a
second run re-parses nothing.
Mythos 5 ($10/$50) is not in LiteLLM or the models.dev/OpenRouter gap-fill
yet (Fable is), so dropping the manual patch left it priced at $0. Add it to
MANUAL_ENTRIES + the snapshot and map the "Mythos 5" display name.
Keep model pricing automatic instead of hand-coding new models. The bundler
now layers three sources in priority order: LiteLLM (broad list prices),
hand-curated MANUAL_ENTRIES overrides, then a separate last-resort fallback
file gap-filled from models.dev first-party makers (official direct prices)
and OpenRouter (resale backstop). New models such as MiniMax-M3 ($0.6/$2.4)
now price correctly with no per-model code.
The fallback is written to its own pricing-fallback.json and consulted only
case-insensitively as the final step in getModelCosts, so a reseller variant
name can never shadow a canonical or aliased match.
Fixes surfaced while building and verifying this:
- Alias precedence: LiteLLM ships snowflake/claude-4-opus ($5), which the
bundler strips to a bare claude-4-opus key that shadowed the curated alias
to claude-opus-4 ($15 official). An explicit alias for a bare name now wins
over a coincidental stripped reseller key; the prefixed gateway price is
still returned for the fully-qualified id.
- Zero-stub guard: LiteLLM [0,0] price stubs (e.g. GigaChat-2-Max) are
excluded from the case-insensitive index so a case-mismatched query stays
null and keeps firing the unknown-model warning instead of silently
reporting $0.
- Negative-sentinel guard: OpenRouter returns -1 for variable/BYOK-priced
models. The bundler now rejects any non-positive rate pair (and strips the
sentinel from cache fields) so a negative per-token cost can never ship and
subtract from spend totals.
Bundler hardening: bareKey strips @pin and date suffixes to match the runtime
canonical form, seen-set dedupes on both full and bare key shapes, and it logs
MANUAL_ENTRIES now covered upstream plus models.dev allowlist drift. Extracted
buildCosts so the cache-cost heuristics live in one place. Added a data-hygiene
test that fails CI if a rebundle reintroduces negative, free, or unreachable
fallback entries.
New Claude releases no longer need a hand-maintained SHORT_NAMES entry or
FAST_MULTIPLIERS row. Display names are derived from the claude-<family>-<major>-<minor>
id, and the fast-mode multiplier rides along as a 5th element in the LiteLLM
snapshot tuple (provider_specific_entry.fast). Fixes#420: claude-opus-4-8 gets
its own line and correct pricing instead of falling into the Opus 4 bucket.
