- Replace the 'missing ?tail means reload' overload with an explicit ?full=1
query param: the frontend's first buffer load after a page load (selectSession)
now requests full=1, tab switches keep ?tail=, and the legacy no-param callers
(response-viewer fallback, clearTerminal refresh) keep the cheap visible-frame
path — the COD-47 feature was previously unreachable from a real reload.
- When the full-history capture succeeds, return it ALONE instead of prepending
the byte buffer + \x1b[H\x1b[2J: the capture is the rendered superset of the
byte history, and ED2 clears only the viewport so the concat replayed the whole
conversation twice in xterm scrollback. The history+clear+frame concat stays
for the visible-frame/tab-switch path.
- Pass an explicit execSync maxBuffer for the full-history capture (configured
terminalBufferMaxBytes + slack) — the 1MB Node default ENOBUFS-killed exactly
the multi-MB captures the feature exists for; log ENOBUFS concisely instead of
dumping the truncated stdout.
- Bound the capture itself via -S -<N> derived from the configured tmux
history limit (was unbounded -S -), and add -J so lines hard-wrapped at the
capture-time pane width reflow in the browser xterm.
- Cap the concatenated buffer to terminalBufferMaxBytes EARLY (before the
regex normalization passes) so multi-MB captures don't stall the event loop
normalizing bytes that get sliced away.
- Tests: route tests updated for ?full=1 semantics (capture-alone response,
config-forwarded capture bounds, byte-history fallback, no-param requests
stay on the visible-frame path); source-scan tests cover the bounded -J -S -<N>
flags and explicit maxBuffer.

A full page reload (GET /api/sessions/:id/terminal with no ?tail=) now captures
the ENTIRE tmux scrollback via capture-pane -p -e -S -, so users get back history
that scrolled off Codeman's byte buffer. Tab switches (?tail=N) keep the fast
visible-frame capture.
- tmux-manager capturePaneBuffer/captureActivePaneBuffer take { fullHistory }:
full-history returns raw linear scrollback (skips the single-screen
formatPaneSnapshot repaint, which would clip multi-screen history).
- /terminal selects full-history on full reload, visible on tail; caps the
payload at the configured terminalBufferMaxBytes (keeps most-recent bytes,
line-aligned) and returns source/fullSize/truncated metadata.
Verified: tsc 0, tmux-capture-full-history 5/5, session-routes 68/68.
Caveat: lines tmux already evicted past its history-limit can't be recovered.
