CB-WP-0007 T01+T03: window the metric, budget it, cap meta at 25%
Scope cut first, on the maintainer's decision after a spend review: the project is 38% product / 62% loop-meta, cost per response is 2.9x worse than its best window, and INTENT stage 0 still lacks a CLI player and bots. CB-WP-0005 and CB-WP-0006 cost ~$74 — 31% of all spend — for zero measured efficiency gain. T02 and T04 are cancelled unstarted. T01: SH-1/SH-2/SH-3 now report over the window since the last commit, and the cumulative figure is retained but labelled "history, NOT the metric". The prediction held decisively — window 655,744 mean context against cumulative 255,307, a 2.6x gap against a 20% refutation threshold. A cumulative mean over 1,094 responses cannot detect a worsening trend because the history outvotes the present. T03: `make shape-budget`, modelled on CB-01/CB-02. Soft thresholds are the existing SessionShape targets; hard is 1.5x, set before the next measurement per §Step 4. Deliberately not in `make all` — failing the build on context would block committing, and committing is what closes the attribution window and is the natural point to compact, so a gate that blocks the remedy is a trap. It fires HARD on its first run: 656,574 against a 300,000 ceiling. InnerLoop v1.5 establishes the soft 25% meta budget. Workplans declare kind: product|meta|mixed and `make status` reports the share; mixed splits 50/50 and says so. Soft on purpose — a task already started may be finished, because stopping mid-task to satisfy a ratio wastes the work. What it forbids is opening new meta work above the line. A pass that exceeds it must say so in its evidence and name the product work displaced. First reading: 68% OVER, of $74.22 attributed. Product reads $0.00 because the only product workplan, CB-WP-0001, predates qualified task ids and its bare T## labels collide across passes — stated in the output rather than papered over.

A spend review before starting found the project **38% product / 62%
|

loop-meta**, with cost per response degraded 2.9× from its best window and
|
||||
INTENT stage 0 still missing a CLI player and bots. CB-WP-0005 and

||||
CB-WP-0006 cost **~$74 — 31% of all spend — for zero measured efficiency
|
||||
gain** (their return was correctness of claims, which is real but is not
|
||||
optimization).
|
||||
|
||||
So this workplan is **cut to T01 and T03**, the two tasks that attack the
|
||||
2.9× regression directly. **T02 and T04 are cancelled**, not deferred —
|
||||
SH-4 trend reporting and the batching trial are more instrument work, and
|
||||
the instrument-failure taxonomy is not converging. T06 becomes the
|
||||
project-level retrospective the maintainer asked for.
|

|

**A soft 25% meta budget is established here** (T03), because the review's
|
||||
finding needs a standing number, not a memory.
