Routes #502. Every finding checked against the current tree before touching anything — TEAMLEAD (session 15b69750), 2026-09-07.

⛔ The audit is half the value: four were already fixed

I nearly "repaired" three things that were already done. The code even cites this issue by number:

status evidence
A1 ✅ already fixed the copy table names .daintree/bootstrap.sh and cites #502 A1/A2
A2 ✅ already fixed the same row states the commit-and-push precondition
A3 ✅ already fixed step 1 tests cli-control.json beside cli.sock
A4 ✅ already fixed step 8 reads "9 of 10, measured 2026-09-06", not the stale "1 of 9"
C5b ✅ already fixed check-orientation returns "void" on an unreadable README — measured: hiding tools/README.md gives exit 2, not a pass

⇒ An open issue listing 14 findings read as 14 open findings. Five were discharged and nothing said so.

Fixed here — five, each with a two-sided control

C1 · validate-recipe.py crashed on valid JSON that isn't an object. json.load accepts any JSON value, so [] reached recipe.get and raised AttributeError. For a validator whose purpose is refusing malformed input, crashing rather than reporting means a caller cannot tell a rejected recipe from a broken validator.

[]          → ERR "top-level JSON is list, not an object"   exit 1
"a string"  → same                                          exit 1
✅ the real recipe                                          exit 0

C2 · fleet-worktree.sh truncated any worktree path containing a space. --porcelain emits worktree <path> with the path as the rest of the line; awk '{print $2}' takes the first word.

worktree /Users/x/Program Files/repo
   old awk → /Users/x/Program              ⛔ silently wrong
   new sed → /Users/x/Program Files/repo

B3 · No .gitattributes, so CRLF re-broke the scripts on every checkout. Committed blobs are LF, but core.autocrlf=true — the Git-for-Windows default — makes the working tree CRLF, and bash executes the working tree: fleet-preflight.sh: line 10: $'\r': command not found. A one-time dos2unix does not hold.

git check-attr eol → lf on .sh/.py/.json/.md      ⛔ CONTROL: LICENSE → unspecified

B4 · The checkers crashed exactly when they found something. The / glyphs appear almost only on FAIL branches, and Windows Python defaults stdout to cp1252 — so a checker ran clean when all was well and died when it detected a defect. A crashed checker reports nothing at all.

Reproduced here, three-way so the cause is not assumed:

OLD + cp1252  →  exit 1, UnicodeEncodeError on '⚠'
OLD + utf-8   →  exit 0            ⇒ the ENCODING, not the file
NEW + cp1252  →  exit 0, zero errors

errors="replace", not a hard switch: a mangled glyph is a legible finding, an exception is not. Applied to all five scripts/check-*.py.

C4 · Three places claimed exit code is always 0 and the implementation disagreed. Measured: forcing one FAIL gives preflight exit 1.

⇒ This is documentation rot, not an open decision. The exit code was deliberately given a verdict — there is a comment block in the Summary section explaining why an acceptance test that cannot fail is worse than none — and two comments plus prompts/README.md were never updated. The docs now state what the code does: 0 clean · 1 blocking · 2 could not establish.

⚠ Whether the pane should gate is untouched and unasked.

Not addressed, named rather than dropped

  • B1 / B2 — Daintree hardcodes PowerShell on Windows; bash from PowerShell resolves to the WSL launcher, so the PREFLIGHT pane measures a different machine than the agents run on. Both need a Windows host to verify and neither is repairable from here.
  • C3 (NODOCTRINE counted but its remediation branch missing), C6 (shell=True blocks vendoring into a repo with a security gate), and Dthe vendoring path defeats the scope discriminator — are doctrine/routing items left for their own disposition. D is the one the reporter most wanted a read on, and it deserves more than a side-effect of this PR.

    • Preflight exit codes now accurately communicate clean, blocking, or indeterminate results.
  • Documentation

    • Updated preflight documentation to describe its exit-code behavior accurately.
  • Chores

    • Standardized line endings for supported text files across platforms.

…h verified before acting

An outside installer vendored this fleet into a foreign repo on Windows 11 / Git Bash and
filed 14 measured findings. Nobody had recorded which were still live. I checked every one
against the current tree before touching anything, and the audit is half the value:

⛔ ALREADY FIXED, and the code says so by issue number — I nearly "repaired" three of these:
  A1  onboard.md's copy table names `.daintree/bootstrap.sh` and cites #502 A1/A2
  A2  the same row states the commit-AND-PUSH precondition
  A3  step 1 now tests `cli-control.json` beside `cli.sock`
  A4  step 8 reads "9 of 10, measured 2026-09-06", not the stale "1 of 9"
  C5b check-orientation returns "void" on an unreadable README — the comment quotes this
      issue's own words. MEASURED: hiding tools/README.md gives exit 2, not a pass.

FIXED HERE, each with a two-sided control:

C1 · validate-recipe.py CRASHED on valid JSON that is not an object. `json.load` accepts
   any JSON value, so `[]` reached `recipe.get` and raised AttributeError — a validator
   whose purpose is refusing malformed input, crashing instead of reporting, so a caller
   cannot tell a rejected recipe from a broken validator.
     [] -> ERR "top-level JSON is list, not an object", exit 1
     "a string" -> same · ✅ the real recipe still exits 0

C2 · fleet-worktree.sh TRUNCATED any worktree path containing a space. `--porcelain`
   emits `worktree <path>` with the path as the REST of the line; `awk '{print $2}'`
   takes the first word. Not hypothetical on Windows.
     `worktree /Users/x/Program Files/repo`
        old awk -> /Users/x/Program        ⛔ silently wrong
        new sed -> /Users/x/Program Files/repo

B3 · NO .gitattributes, so CRLF re-broke the scripts on every checkout. Committed blobs
   are LF, but `core.autocrlf=true` — the Git-for-Windows DEFAULT — makes the WORKING TREE
   CRLF, and bash executes the working tree: `fleet-preflight.sh: line 10: $'\r': command
   not found`. A one-time dos2unix does not hold; this pins it.
     git check-attr eol -> lf on .sh/.py/.json/.md · CONTROL: LICENSE -> unspecified

B4 · THE CHECKERS CRASHED EXACTLY WHEN THEY FOUND SOMETHING. The ⛔/⚠ glyphs appear almost
   only on FAIL branches, and Windows Python defaults stdout to cp1252 — so a checker ran
   clean when all was well and died with UnicodeEncodeError when it detected a defect. A
   crashed checker reports nothing at all. Reproduced here under PYTHONIOENCODING=cp1252,
   three-way so the cause is not assumed:
     OLD + cp1252 -> exit 1, UnicodeEncodeError on '⚠'
     OLD + utf-8  -> exit 0        ⇒ the ENCODING, not the file
     NEW + cp1252 -> exit 0, zero errors
   errors="replace", not a hard switch: a mangled glyph is a legible finding, an exception
   is not. Applied to all five scripts/check-*.py.

C4 · THREE PLACES CLAIMED "exit code is always 0" AND THE IMPLEMENTATION DISAGREED.
   Measured: forcing one FAIL gives preflight exit 1. ⇒ This is DOCUMENTATION ROT, not an
   open decision — the exit code was deliberately given a verdict, with a comment block
   explaining why, and two comments plus prompts/README.md were never updated. So the docs
   now state what the code does (0 clean · 1 blocking · 2 could not establish). ⚠ Whether
   the pane should GATE remains untouched and unasked.

NOT ADDRESSED, and named rather than dropped: A3-adjacent Windows behaviour, B1/B2
(Daintree hardcodes PowerShell; `bash` resolves to the WSL launcher) — both need a Windows
host to verify and neither is repairable here. C3, C6 and D (the vendoring path defeats the
scope discriminator) are left for their own routing.

📝 Walkthrough

Walkthrough

The pull request adds cross-platform text and checker-output handling, documents preflight exit statuses, preserves worktree paths containing spaces, and returns validation errors for non-object recipe JSON values.

Changes

Cross-platform validation

Layer / File(s) Summary
Platform line endings and checker output
.gitattributes, scripts/check-*.py
LF endings are enforced for selected file types. Five Python checkers configure UTF-8 output with replacement handling when stream reconfiguration is available.
Preflight exit-status documentation
scripts/fleet-preflight.sh, prompts/README.md
Documentation records exit codes 0, 1, and 2, and states that the preflight reports status without gating fleet execution.
Worktree path extraction
scripts/fleet-worktree.sh
The main worktree path is extracted with sed so spaces remain part of the path.
Recipe JSON shape validation
scripts/validate-recipe.py
Non-object top-level JSON values now produce a validation error instead of an AttributeError.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 2da60

This change improves cross-platform validation, but worktrees located in paths with spaces can still produce an incorrect preflight repository value, and custom output wrappers can cause checkers to fail at startup. These are bounded tooling issues that should be corrected before relying on the new behavior in those environments.

… I found by sweeping

1. PER-STREAM GUARDS. I wrote `if hasattr(sys.stdout, "reconfigure")` and then
   reconfigured BOTH streams inside it. `hasattr` on stdout says nothing about stderr —
   a harness may replace one and not the other, and this repo's own stubbed suites
   capture streams — so the guard meant to prevent an AttributeError could raise one.
   Demonstrated both ways against a stderr with no `.reconfigure`:
     buggy guarded form -> ATTRIBUTEERROR 'Fake' object has no attribute 'reconfigure'
     per-stream form    -> EXIT 0
   Applied to all five scripts/check-*.py.

2. ⛔ THE SPACE-TRUNCATION FIX WAS INCOMPLETE, AND THE REVIEW FOUND ONE MORE SITE THAN
   I HAD. `scripts/fleet-preflight.sh:36` carried the same `awk '{print $2}'` over the
   same porcelain output. ⇒ So I stopped fixing FILES and swept for the PATTERN — which
   turned up a THIRD site the review did not name: `fleet-worktree.sh:59`, inside
   `where()`, doing `p = $2` on the same input.

   All three now take the rest of the line:
     worktree /srv/Program Files/repo
        sed    -> /srv/Program Files/repo
        substr -> /srv/Program Files/repo
        ⛔ $2  -> /srv/Program
   ⛔ CONTROL: zero field-2 porcelain parses survive anywhere under scripts/.

★ THE LESSON IS THE SWEEP, NOT THE PATCH. I had fixed the instance named in the issue and
called the finding routed. It was a CLASS with three members, and the third would have
survived both the original report and the review that caught the second.
