Correct the sweep provenance in both summaries.

The PR objectives state that the workflow engine was unavailable and that the migration used the sanctioned LLM-only process plus manual finalization. Update both documents to record that process instead of claiming the triage-friction-log workflow performed the sweep.

In `@docs/kit-friction-log-archive.md` at line 8, Update both summary attributions
to state that the workflow engine was unavailable and the sweep used the
sanctioned LLM-only process with manual finalization. Apply this change in
docs/kit-friction-log-archive.md:8 and docs/kit-friction-log.md:16-18; remove
the claim that triage-friction-log performed the sweep while preserving the
entry count and accounting status.

**twelve graduated** into eight issues ([#70](https://github.com/topij/agentic-dev-kit/issues/70)–[#77](https://github.com/topij/agentic-dev-kit/issues/77)),
four of which each merge two entries recorded on separate days; **one** recorded a
measurement with *"No change proposed"*. All thirteen are kept below for the trail,
along with the prior graduation marker.

### 2026-07-26 — Backlog migrated to GitHub Issues (#54–#56)

The inbox was swept by the `triage-friction-log` workflow. Three entries graduated:

- [#54](https://github.com/topij/agentic-dev-kit/issues/54) — every verification claim
must name the command that establishes it (supersedes the narrower "wrap-up should
fact-check the handoff" proposal).
- [#55](https://github.com/topij/agentic-dev-kit/issues/55) — `safety-critical-changes.md`
rule 1 should name a tightening threshold.
- [#56](https://github.com/topij/agentic-dev-kit/issues/56) — removing a mechanism
requires enumerating what it was rejecting.

Three further entries needed no ticket: their proposed fixes had **already shipped** in
PR #31 — the panel contract now requires lenses to execute and mutation-test (contract
items 4–5), rule 3 carries the blast-radius stopping criterion, and contract item 7
mandates isolated worktrees.

The remaining five: four were already tagged with an issue id (#10, #18, #19, #33), and one
recorded a guard working correctly with *"No change proposed"*. Eleven entries in, eleven
accounted for.

Everything above now lives in [`kit-friction-log-archive.md`](kit-friction-log-archive.md).

### 2026-07-27

- **A mutation harness that restores outside `finally` leaves the repo mutated.** My
restore line was unreachable when the script died parsing pytest output (a bare
`python3` with no pytest returned no stdout, and `splitlines()[-1]` raised). The
working tree kept a live mutant until `git status` caught it. Neither existing warning
covers it: `#50` is about stale `.pyc`, and `fallback-review-panel.md` contract item 5
warns only about **false kills** from a checksum/drift test (it does not mention
`.pyc` at all). Both frame the hazard as "the result may be wrong"; neither says the
repo may be left broken. **H** —
proposed fix: contract item 5 should say the restore belongs in a `finally` (or a
git-clean check) and that any harness must verify the tree is clean *after* it exits,
not only after a successful run.
- **The closing-keyword trap fired again, because I weakened a correct rule on the
strength of an experiment that did not test what I thought.** `#61` was closed by the
squash-merge of `#68` and reopened by hand.

**What is actually measured** — three data points, with their confounds stated,
because two earlier write-ups of this stated more than the data supports:

| artifact | form | outcome |
| --- | --- | --- |
| `#68` body | `Closes #61` inside a **fenced block** | inert (`closingIssuesReferences: []`) |
| `9c6ab3a` commit message | `Closes #61` in an **inline** span | **fired** — closed `#61` |
| `#63` body | `Does NOT close #60` **and** a plain `fix #60` | fired; which one is **not isolated** |

**What is NOT measured, though I twice wrote as if it were:** whether an *inline* span
is inert in a PR body. The two backtick data points differ in **two** variables at once
— fenced-vs-inline *and* body-vs-commit — so "GitHub excludes inline code spans" and
"fenced blocks are inert everywhere, inline spans fire everywhere" fit the evidence
equally well. Under the second reading, the fix I proposed last round (strip inline
code from a PR body before checking) reopens the exact hole that closed `#61`.

Likewise the *negation* hypothesis: `#63`'s body carries a plain, non-negated `fix #60`
alongside the negated mention, so a check that only flags keywords **near a negation**
would have passed that body clean.

**H** — **stop deriving a mechanism; take the conservative rule.** Three attempts to
state this precisely have each been wrong, which is rule 1's threshold. The original
2026-07-26 rule below — never write a closing keyword adjacent to an issue number you
do not intend to close, in any form, on any surface — would have prevented all three
incidents; the measurement talked me *out* of a correct rule. It stands as written, and
the proposed check follows it rather than any theory of markdown:

- flag **every** match on **every** surface — PR body, every commit message, and the
squash message — with **no stripping** of code spans or fenced blocks;
- cover the forms the naive regex misses and GitHub honours: `owner/repo#61`, a full
issue URL, and `Closes: #61` (a colon, not whitespace);
- check the **squash message at merge time** specifically. It is composed *after* the
PR body was reviewed, and nothing reviews it — verified: `9c6ab3a`'s message matches
neither `#68`'s title, its body, nor any of its three branch commits, and no hook in
`scripts/` inspects commit messages at all;
- the operator confirms each match. Over-firing is the acceptable failure here.

Occurrence count, corrected: **three occurrences across two sessions** (`#63` and `#64`
were the same session; `9c6ab3a` is this one).
- **A review bot with an incremental model keeps a stale review across a rewrite.**
CodeRabbit reviewed the pre-split head, then declined `@coderabbitai review`
("does not re-review already reviewed commits") and hit its Fair Usage limit on
`@coderabbitai full review`. The PR was force-pushed and then substantially rewritten,
so the only bot review covered code that no longer existed. `pr_watch`'s
`bots_behind_head` recorded it correctly — the friction is that **nothing warns at
push time**, when re-requesting is still cheap. **M** — proposed fix: have `pr-watch`
surface `covers_head: false` as a distinct, louder line right after a push that
changes the diff shape, rather than only at receipt time. Related: `#27`, `#44`.
- **The panel's worth is disjointness, and this run measured it.** Round 1: the
adversarial lens found the enclosing-repo and `GIT_DIR` regressions; the correctness
lens independently found the `~`-expansion disagreement between `init.sh` and the new
detector. Almost no overlap. Round 2's correctness lens then found the *misattributed
defect* — a false sentence in the commit message written to describe round 1's own
outcome, which could not have existed when round 1 ran. **No change proposed** —
recording it because `fallback-review-panel.md` argues disjointness from one prior
data point, and this is a second, stronger one worth citing there. Note the honest
framing of what the panel beat: the four regressions were missed by CI, by the suite
**as it then stood**, and by the mutation run **at that head** — not by the 372-test
suite quoted elsewhere, which only exists *because* those findings were fixed.
- **The archive sweep broke a cross-reference again — and this time it broke one the
PREVIOUS sweep had written.** The 2026-07-26 entry below reports the sweep orphaning
*"see the Phase 3b block above"*. Today's sweep moved Phase 3b itself into the history
file, so the surviving text — *"see the Phase 3b block, still live in
kit-handoff.md"* — became false in a second way: the target is now in the very file
the sentence sits in. Fixed by hand in this commit. **M** — the entry below proposes
warning on `(above|below)`-style references in *moved* blocks; this instance shows the
warning must also cover references **into** a moved block from anywhere in either
document, since the block that moved was the reference's *target*, not its location.
Same family as `#53`.
- **The doc-budget remedy no-op reproduced a third time** (see the 2026-07-26 entry
below). `check_doc_budget` reported 421/400; the remedy it names printed *"nothing to
move: 5 session block(s) <= --keep 6"*; `--keep 4` was needed and found by guessing.
**No new fix proposed** — recording the third occurrence. The entry below already
records two; this makes it three, two of them in *this* repo, which is a pattern
rather than a run of bad luck.
- **A review lens's isolated worktree pointed at the wrong ref again — 5 of 5 this
session, 9 of 9 across two.** (Last session's entry below records 4 of 4; this session
ran 2 lenses × 2 rounds on `#65` plus 1 on `#68`.) Every lens detected it and cloned
the target itself, because the prompt required reporting the path and diff stat.
**H** — proposed fix: this is no longer a
caveat, it is the default behaviour. Contract item 7 should stop saying "verify" and
start saying "assume the worktree is wrong; clone the target yourself first", with the
path/diff-stat report as a required field of the lens output (the existing 2026-07-26
entry proposed the report; this one is about inverting the default).

### 2026-07-26

- **The doc-budget remedy does not fire at the default `--keep`.** `check_doc_budget`
measures **lines**; `archive_plan_sessions` keeps **blocks**. This handoff hit
448/400 lines with 5 blocks, so the remedy the warning names printed *"nothing to
move: 5 session block(s) <= --keep 6"* and the file stayed over budget. The agent has
to guess a `--keep` and re-run until the line count drops — which is exactly the
manual fiddling the deterministic engine exists to remove. **M** — proposed fix: give
`archive_plan_sessions` a `--target-lines` mode (sweep oldest-first until under
budget), or have `check_doc_budget`'s remedy string compute and name the `--keep` that
would work. Reproduced twice this session (kit and cs-toolkit).
- **A runtime's isolated worktree points at the session's base ref, not the PR head.**
All **four** review-lens launches this session (2 lenses × 2 rounds) landed on `main`
with an empty `git diff main...HEAD`. Every one detected it and cloned the real target
— because the launch prompt required them to *report the path and diff stat they saw*.
`fallback-review-panel.md` contract item 7 says to verify; what actually surfaced it
was making the report **mandatory output**. **H** — proposed fix: promote "state the
path reviewed and the diff stat" from advice to a required field of the lens report in
contract item 8, and say plainly that a lens which cannot show a non-empty diff has not
reviewed anything. A clean pass over an empty diff is indistinguishable from a real one.
- **`--record-review` has no way to record honest partial coverage.** It correctly
refuses a receipt bound to a stale head (`PR head changed during review`), but the only
alternative is a receipt claiming the current head — which the panel did not review. So
the honest choice is **no receipt at all**, and the audit trail then loses the fact that
a two-lens panel ran at all. **M** — proposed fix: allow recording against the reviewed
sha with the head-gap represented rather than rejected (the existing `bots_behind_head`
field is the precedent). Related: #32.
- **Negating a GitHub closing keyword still arms it.** A PR body was edited before merge
to retract a closure claim; the retraction read *"Does NOT close #60"*. GitHub matched
`close #60`, and merging closed an issue documenting an **unfixed** bug. Caught after
the fact and reopened. **M** — proposed fix: one line in the wrap-up / pr-watch
doctrine — never write a closing keyword adjacent to an issue number you do not intend
to close, even negated; write "#60 stays open". cs-toolkit's `CLAUDE.md` already carries
the Linear-side twin of this hazard.
- **The cockpit edited the shared tree while lenses were reviewing it.** A lens reported
the shared checkout changing mid-run (5 files, mtimes inside its window) and correctly
noted it was not the author. Its own review was unaffected — it worked from an isolated
clone — but it had to spend output distinguishing "concurrent editor" from "corruption".
Contract item 7 constrains the **lenses**; nothing constrains the **cockpit**. **M** —
proposed fix: add a cockpit-side clause — do not mutate the shared tree between
launching a panel and reading its findings.
- **The archive sweep breaks *relative* cross-references, and its docstring says it
doesn't.** `archive_plan_sessions.py:20` claims *"It only ever moves content — every
cross-reference (ticket ids, PR links, commit shas, …) is preserved."* Every kind it
enumerates is **absolute**. A relative one is not preserved: this session's sweep moved
the Phase 3a block into the history file while Phase 3b stayed live, orphaning
*"see the Phase 3b block above"* — the target is now in a different file. Caught by
CodeRabbit on the wrap-up PR, not by the sweep, which reported success. **M** —
proposed fix: have the sweep scan moved blocks for `(above|below)`-style references
and warn (not rewrite — rewriting is the class of surgery `init.sh`'s deleted marker
migration proved dangerous). Same family as #53, which is about the pointer the sweep
*writes*; this is about the references it *carries*.
